1 INTRODUCTION

This Health and Safety Plan (HSP) has been designed to protect the health and

safety of project personnel and the surrounding community The purpose of the plan is to

assign responsibilities establish personal protection standards and mandatory safety

practices and procedures and provide for contingencies that may arise while operations

are being conducted at the WR Grace amp Co - Conn (Grace) Acton Superfund Site (the

Site) The HSP incorporates the Occupational Health and Safety (OSHA) requirements

presented in 29 CFR Part 1910 The selection of the level of personal protective

equipment (PPE) is based on OSHA Permissible Exposure Limits (PELs) the American

Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values

(TLVs) and the National Institute for Occupational Safety and Health (NIOSH)

Recommended Exposure Limits (RELs) The Workplace Hazard Assessment

Certification required by 29 CFR Part 1910132 is provided following the signature page

for this HSP Detailed information on the HSI GeoTrans comprehensive corporate health

and safety program is contained in the Terra Tech Inc Health and Safety Manual (HSI

GeoTrans is a wholly owned subsidiary of Tetra Tech) Included in this manual is

information on corporate programs including the Health and Safety Audit Program

(Volume 1 Section 1-3) and the Personnel Protective Equipment Program (Volume 1

Section 2-7)

The provisions of the HSP are mandatory for all on-Site HSI GeoTrans

employees They set forth minimum requirements for other contractors involved in the

field activities For contamination investigations it is required that each field contractor

provide a HSP for its employees covering any exposure to hazardous materials and

complete all work in accordance with that plan HSI GeoTrans maintains no

responsibility whatsoever for the safety and welfare of any on-Site personnel except for

their own employees

1123 SITE EMERGENCY PROCEDURES

FireExplosion

A fire that cannot be readily extinguished with one ten pound fire extinguisher

will be considered major and may require evacuation of Site personnel to safe areas The

SSO will call the fire department and will coordinate with fire emergency personnel as to

the selection of protective clothing and equipment as well as the use of proper fire

FOR wR GRACE amp Co - CONN M Wgt DOCSN0992000FINA1 PHASE I RIX02251600 wpo APR D1-6 HSI GeoTrans inc

fighting techniques The air downwind from any fireexplosion is to be monitored

immediately in order to protect workers and the nearby community If so required by the

air monitoring results the Vapor Emission Response Plan will be placed into effect If

personal injuries result from any fire or explosion the procedures outlined in the Personal

Injury Response Plan will be followed

Hazardous Spill

Any release or threat of release occurring during the work that constitutes an

emergency or may present an immediate threat to public health welfare or the

environment will be reported by the SSO or clients representative to the government

parties In the event of a spill the two main goals are to contain the spill as much as

possible and to minimize vapor emissions In order to accomplish these goals the

following equipment should be available at the Site

(1) an empty container

(2) polyethylene sheets

(3) absorbent materials and

(4) a shovel

Vapor Emission Response Plan

If any of the following conditions are identified at the Site exclusion zone

boundary all activities must be halted

(1) organic levels observed on air monitoring equipment of unknown

constituents are greater than 5 ppm above known background or

action levels requiring evacuation are reached or

(2) LEL levels greater than 10

If following the cessation of activities or as the result of an emergency

such as that described in the section on FireExplosion any of the above levels

persist downwind from the Site at the boundary of the exclusion zone then this

FOR W R GRACE amp Co - CONN MWP_DOCSW0992000F1NALPHASEIRI022SI600WPD APP D1-7 HSI GfiOTfanS lllC

Emergency Plan will automatically be placed into effect Upon activation of the

Emergency Plan the nearest perimeter of the closest downwind residential or

commercial property will immediately be monitored If organic levels from an

unknown source approach 5 ppm the local police authorities or property owner

will immediately be contacted by the SSO or clients representative and advised of

the situation

Personal Injury Response Plan

Accidents - Depending on the seriousness of the injury treatment may be

given at the Site by the SSO For more serious injuries additional assistance by

ambulance may be required at the Site or the victim may have to be treated at a

medical facility The SSO will assess the seriousness of the injury and will

consult by phone with a physician if necessary The SSO will file a complete

incident report with the Office Health and Safety Officer and the Project

Coordinator as soon as possible

Chemical Overexposure - Personnel including unauthorized personnel

that suffer chemical overexposure shall be treated in the following manner

bull Skin Contact Remove contaminated clothing Wash immediately with water Use soap if available

bull Inhalation Remove from contaminated atmosphere Artificial respiration if necessary Transport to hospital

bull Ingestion Never induce vomiting on an unconscious person Also never induce vomiting when acids alkalis or petroleum products are suspected Contact the poison control center

These personnel shall be observed by the SSO to ascertain whether there

are any symptoms resulting from overexposure If there is any visible

manifestation of overexposure such as skin irritation Project Personnel should be

FOR WR GRACE amp Co - CONN MWP DOCSN0992000F1NAL PHASE I RI02251600 WPD APP D1-8 HSI GeOTfanS IRC

examined by a physician All episodes of obvious chemical contamination are to

be reviewed by the SSO in order to determine whether changes are needed in

work procedures The SSO will file a complete incident report with the Office

Health and Safety Representative and the Project Coordinator as soon as possible

Radiation

Background for ionizing radiation is normally 001 to 005 mRhr

Background levels at the site that exceed these values should be listed under

background information If levels exceed background but are less than 1 mRhr

the investigation may continue with caution If levels exceed 1 mRhr all

activities must stop and personnel must evacuate the Site or portions of the Site

that exceed 1 mRhr

113 BACKGROUND INFORMATION

Overall Risk is High Moderate _

Low Unknown

1131 FACILITY DESCRIPTION

The Site is located in Acton and Concord Massachusetts on Independence Road

The Grace property is bordered by residential property on the northwest east and west

and industrial properties to the south and northeast Fort Pond Brook bounds the Grace

property to the northwest and the Assabet River bounds the Grace property to the

southeast The Assabet well field which supplies water for the Town of Acton is located

southwest of the Grace property Two inactive sand and gravel pits Massachusetts

Broken Stone Pit and Assabet Sand and Gravel are located south of the Grace property

Former occupants of the Site include American Cyanamid Company which

manufactured explosives and Dewey amp Almy Chemical Company Dewey amp Almy

acquired the property in 1946 and manufactured synthetic rubber container sealant

products An organic chemical plant which produced latex products plasticizers and

resins commenced operation in 1949 A paper battery separator production facility was

constructed in 1951

Grace acquired Dewey and Almy in 1954 and chemical operations were

continued at the Site Grace produced materials used to make concrete and organic

chemicals container sealing compounds latex products and paper and plastic battery

separators Wastewater and solid industrial wastes from these operations were disposed

in several on-site lagoons and an on-site landfill In addition the by-products of some

chemical processes were disposed of in the Slowdown Pit located in the central portion of

the property (Figure 1-2) Discharge to these areas ceased in 1980 Production of organic

chemicals was discontinued in 1982 A small distribution center for concrete additives

(Grace Construction Products) was moved to another location in September 1996 A

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINAL PHASE I RI022S1600 WPD APPD1-11 HSI GeOTianS lllC

second battery separator plant (Daramic) was constructed in 1979 and operations there

continued until 1991 The Daramic facility has not been considered part of the Site All

buildings with the exception of the building associated with the ARS have been

demolished

In 1978 groundwater contamination consisting mainly of 11-dichloroethene

(VDC) and lesser amounts of vinyl chloride ethylbenzene and benzene was detected in

two Acton municipal supply wells Assabet 1 and Assabet 2 located southwest of the

Grace property This discovery prompted a series of investigations which culminated in

the installation of the ARS beginning in late 1983 The ARS is a network of eleven

extraction wells designed to contain and cleanup contaminated groundwater and it is

currently operational

Following installation of the ARS extensive investigations were done by Grace

on in beneath and immediately surrounding the source areas to determine the nature and

extent of contamination by waste disposal practices Following a complete engineering

analysis of cleanup and remedial alternatives for the sources referred to as Operable

Unit-1 (OU-1) a remedy was selected for OU-1 Implementation of the remedy began in

November 1994 and was completed in July 1997 Following completion of the OU-1

remedy a comprehensive review of the groundwater quality and groundwater flow

conditions observed at the Site since the early 1980s and an evaluation of the

effectiveness of the ARS to contain and remediate groundwater affected by the Site was

done in the Initial Site Characterization Report (ISCR) (HSI GeoTrans 1998) While

data reviewed in the ISCR indicated that most areas of the Site containing groundwater

contamination are within the ARS capture zone and that contaminant concentrations in

most wells located outside of the capture zone have decreased significantly since 1984

uncertainties remain regarding the flow of groundwater and the distribution of

contaminants in certain areas of the Site The RIFS is designed to evaluate the extent of

FOR WR GRACE amp Co - CONN M wp_DocsN0992ooofiNALpnASEiRno225i6oowpo APPD1-12 HSI GeoTrans inc

groundwater contamination on- and off-Site and to determine whether additional remedial

measures are necessary to ensure accelerated restoration of the groundwater affected by

the Site to a fully usable condition

The Site property is now inactive as a manufacturing center The perimeter is

identified but due to the size is not secured Access to the Site is controlled through

locked gated entrances and exits The surrounding area is heavily wooded and restricts

the entrance of vehicles to the Site

1132 EXISTING CHEMICAL DATA

The existing historical chemical data for the Site has been compiled through a

thorough review of past activities at the Site and a review of the Site electronic database

For the purposes of this HSP only data collected after the completion of the source

removal activities will be used to evaluate health and safety concerns at the Site The

electronic database was queried in March of 1999 to determine the maximum

concentration and frequency of compounds detected in groundwater at the Site since

January 1 1996 (Table 1-1)

The volatile organic compounds (VOCs) with the highest frequency of detections

and maximum detection shown in parentheses at the Site are benzene (8600 ugL)

VDC (1000 ugL) and vinyl chloride (280 ugL) The semi-volatile organic compounds

(SVOCs) with the highest frequency of detections and maximum detection shown in

parenthesis at the Site are diethlyphthalate (110 ugL) bis(2-ethylhexyl)phthalate (120

ugL) and bis(2- chloroethyl)ether (41 ugL) The inorganic compounds with the highest

frequency of detections and maximum detection shown in parenthesis at the Site are

arsenic (13000 ugL) aluminum (42000 yUgL) nickel (890 ugL) and cadmium (16

ugL) The groundwater data collected indicate that pesticides and PCBs are not a

concern at the Site (HSI GeoTrans 1998) Therefore no pesticides or PCBs will be

monitored for during work tasks at the Site

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINM PHASE I RI0225I600 wro APPD1-13 HSI GeOTfanS lllC

Other compounds have been detected at varying concentrations and at a wide

range of frequencies at the Site Because such a wide range of VOCs SVOCs and

inorganics have been detected at the Site it was necessary to screen these compounds for

potential health hazards and exposure risks A full discussion of the potential health

hazard and exposure risk screening is provided in Attachment A Attachment A also

includes tables which indicate the physical description and associated health hazards for

each compound detected at the Site (Attachment A Table A-l) the exposure limits and

monitoring properties for each compound detected at the Site (Attachment A Table A-2)

compounds with gas and vapor exposure limits less than 5 ppm (Attachment A Table Ashy

3) compounds with particulate exposure limits less than 1 mgm3 (Attachment A Table

A-4) and a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) (Attachment A Table A-5)

Based on the screening discussed in Attachment A it was determined that the

compounds listed in Table 1-2 are contaminants of monitoring concern These

compounds have vapor exposure limits less than 5 ppm have been detected at least four

times and have a maximum detection concentration greater than 10 ppb (ugL) The

compounds found at the highest frequency and with greatest maximum concentration at

the Site benzene VDC and vinyl chloride are included in the list of compounds of

monitoring concern and comprise the lowest exposure limits Therefore benzene VDC

and vinyl chloride will be used as indicator compounds for vapor monitoring during work

tasks No dust monitoring will be conducted Work practices and investigation derived

waste (IDW) management practices will be used that will minimize the potential for

contaminated soil to be suspended in breathing space air Because vapor monitoring

action levels are lower than LEL action levels (10 percent of the LEL) no LEL

monitoring is required aside from that associated with confined space entry of the

recovery well vaults

POTENTIAL HEALTH HAZARD AND EXPOSURE RISK SCREENING

FOR WR GRACE amp Co - CONN M wp_Docswo992oooFiNALpiiASE i wo225 i6oo wro ATTA1-1 HSI GeoTrans inc

POTENTIAL HEALTH HAZARD AND EXPOSURE RISK SCREENING

The historical chemical data for the Site has been compiled through a thorough

review of past activities at the Site and a review of the Site electronic database For the

purposes of this HSP only data collected after the completion of the source removal

activities will be used to evaluate health and safety concerns at the Site The electronic

database was queried in March of 1999 to determine the maximum concentration and

frequency of compounds detected in groundwater at the Site since January 1 1996 (see

Table 1-1)

A hazard screening evaluation was performed for each compound identified in the

database search described above Table A-l indicates the associated health hazards

(exposure routes symptoms and target organs) for compounds detected at the Site and

the physical description (eg color solidliquidgas phase odor) Compounds for which

the NIOSH guide (NIOSH 1998) did not contain health hazard or physical description

information are shown with no information in the table row Some physical descriptions

for compounds were gathered from other sources (See Table A-l citation notes)

Table A-2 provides the exposure limits a summary of daily time weighted

average (Per Day TWA) and the 15 minute short term (15 min STEL) ceiling and

immediately dangerous to life or health (IDLH) exposure limits The limits shown are the

most stringent quantified exposure limits put forth by OSHA NIOSH and ACGIH for

each exposure limit category

Compounds that NIOSH considers to be potential occupational carcinogens are

designated with a check in the CA box in Tables A-2 A-3 and A-4 NIOSH usually

recommends that occupational exposures to carcinogens be limited to the lowest feasible

concentration (LFC) Those compounds NIOSH has identified as potential carcinogens

but has not quantified recommended exposure limits (REL) are designated with LFC

under the Most Stringent Exposure Limit column in Attachment A Table A-3 The

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINA1 PHASE I RT02251600 WPD ATT A1 -2 HSI GeOTiaHS lllC

ACGIH has categorized compounds into five carcinogenicity groups based on available

information Al for confirmed human carcinogens A2 for suspected human carcinogens

A3 for confirmed animal carcinogen with unknown relevance to humans A4 for not

classifiable as a human carcinogen and A5 for compounds not suspected as a human

carcinogen The carcinogenicity category for compounds which ACGIH has designated

is also shown in Tables A-2 A-3 and A-4

The compounds that have potential air monitoring concerns for this Site are those

compounds designated in Table A-3 with LFC an ACGIH carcinogenicity of Al or A2

a gas and vapor exposure limit of 5 ppm or less or with a suspended-in-air particulate

exposure limit of 1 mgm3 or less Tables A-3 and A-4 summarize the most stringent gas

and vapor and particulate exposure limits for these compounds respectively

The compounds with gas and vapor exposure limits of 5 ppm or less which were

detected at low frequency and low concentration (three or fewer times and at a

concentration less than 10 ppb (^gL)) are not considered to be of monitoring concern

(Table A-3) The remaining compounds in Table A-3 have only been detected at

locations where the concentration of benzene VDC and vinyl chloride represent the

majority of the total concentration of chemicals with monitoring concerns Because the

exposure limits for benzene VDC and vinyl chloride are low and these compounds make

up the majority of contamination in groundwater at the Site monitoring for benzene

VDC and vinyl chloride is a conservative means to evaluate work task exposure risks

which establish action level PPE modifications In order to screen for the compounds in

Table A-3 detector tubes or other compound specific monitoring devices for the indicator

parameters (benzene VDC and vinyl chloride) will be used according to action levels

associated with the tasks to be performed

The compounds with a suspended-in-air particulate exposure limit of 1 mgm3 or

less which were detected at low frequency and low concentration (three or fewer times

and at a concentration less than 10 ppb (^gL)) are not considered to be of monitoring

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FlNALPHAbElRI02251600 WO ATTA1-3 HSI GCOTfanS 1HC

concern (Table A-4) Work practices and investigation derived waste (1DW)

management practices will be used that will minimize the potential for contaminated soil

to be suspended in breathing space air above the exposure levels for the remaining

compounds

Table A-5 is a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) Because vapor monitoring action

levels are lower than LEL action levels (10 percent of the LEL) no LEL monitoring is

required

PERSONAL INJURY RESPONSE PLAN

Accidents

Physical injuries can range from a sprained ankle to a compound fracture or from a

minor cut to massive bleeding Depending on the seriousness of the injury treatment

may be given at the site by the Site Safety Officer For more serious injuries additional

assistance by ambulance may be required at the site or the victim may have to be treated

at a medical facility The Safety Officer will assess the seriousness of the injury and will

consult by phone with a physician if necessary

Chemical Exposure

Personnel including unauthorized personnel that suffer chemical overexposure shall

be treated in the following manner

bull Skin Contact Remove contaminated clothing Wash immediately with water Use soap if available

bull Inhalation Remove from contaminated atmosphere Artificial respiration is necessary Transport to hospital

bull Ingestion Never induce vomiting on an unconscious person Also never induce vomiting when acids alkalis or petroleum products are suspected Contact the poison control center

bull Ionizing Radiation Normal background 001 to 005 mRhr If less than 1 mRhr continue investigation with caution If greater than 1 mRhr evacuate site

These personnel shall be observed by the Site Safety Officer to ascertain whether

there are any symptoms resulting from overexposure If there is any visible manifestation

of overexposure such as skin irritation Project Personnel should be examined by a

physician All episodes of obvious chemical contamination are to be reviewed by the Site

Safety Officer in order to determine whether changes are needed in work procedures

Cold Stress

Persons working outdoors in temperatures at or below freezing may be frostbitten

Exposure to extreme cold for a short time may cause severe injury to the surface of the

body or result in profound generalized cooling causing death Areas of the body that

have a high surface-area-to-volume ratio such as fingers toes and ears are the most

susceptible Two factors influence the development of a cold injury ambient temperature

and the velocity of the wind Wind chill is used to describe the chilling effect of moving

air in combination with low temperature For instance 10degF with a wind of 15 mph is

equivalent in chilling effect to still air at -18degF

As a general rule the greatest incremental increase in wind chill occurs when a wind

of 5 mph increases to 10 mph Additionally water conducts heat 240 times faster than

air Thus the body cools suddenly when chemical-protective equipment is removed if the

clothing underneath is soaked with perspiration Local injury resulting from cold is

included in the generic term frostbite There are several degrees of damage

Systemic hypothermia is caused by exposure to freezing or rapidly dropping

temperature Its symptoms are usually exhibited in five stages (1) shivering (2) apathy

listlessness sleepiness and (sometimes) rapid cooling of the body to less than 95 degF (3)

unconsciousness glassy stare slow pulse and slow respiratory rate (4) freezing of the

extremities and finally (5) death

Prevention of Cold Stress can be achieved by (1) Modification of work schedules as

required by site conditions and personnel monitoring (2) Provision of shelters to protect

workers during rest periods (3) Maintenance of body heat at normal levels by wearing

adequate layers of clothing (4) Training site personnel to recognize and treat cold stress

(5) Frequent warm up breaks (6) Acclimation

Heat Stress

Wearing personal protective equipment puts a field worker at considerable risk of

developing heat stress This can result in health effects ranging from transient heat

fatigue to serious illness or death Heat stress is an aggregate of all the heat factors both

internal and external that work on the body

FOR WR GRACE amp Co - CONN MWP_DOCSNON2000F[NALP11ASEIRI0225600WPO ATT B1-18 HSI GCOTfanS IHC

External factors that contribute to heat stress include ambient air temperature

radiant temperature air velocity and the relative humidity Internal factors include

metabolic heat body core temperature respiration rate and acclimation

Early symptoms of heat stress include mental confusion and the inability to

concentrate heat rash and heat cramps (muscle spasms andor pain in hands feet and

abdomen) Acute and chronic heat stress impacts a workers temperament causing

impulsive aggressive and violent acts to be committed by the victim Signs of heat

exhaustion include pale cool moist skin heavy sweating dizziness nausea and fainting

Heat stroke is the most serious form of heat stress Immediate action must be taken to

cool the body and prevent serious injury Competent medical help must be obtained

Signs include red hot dry skin lack of or reduced perspiration nausea dizziness and

confusion strong rapid pulse and coma The case-fatality of heat-stroke and heat

exhaustion is probably no lower than 10 percent Because heat stress is one of the most

common (and potentially serious) illnesses at field sites regular monitoring and other

preventative precautions are vital

To monitor for heat stress measure

(1) Heart rate mdash Count the radial pulse during a 30-second period as early as possible during rest periods If the heart exceeds 110 beats per minute at the beginning of the rest period shorten the next work cycle by one-third and keep the rest period the same If the heart rate still exceeds 110 beats per minute at the next rest period shorten the following work cycle by one-third again

(2) Oral temperatures mdash Use an oral thermometer to measure the oral temperature at the end of the work period (before drinking) If oral temperature exceeds 996 degrees F shorten the next work cycle by one-third without changing the rest period Repeat if necessary Do not permit a worker to wear PPE when the workers oral temperature is above 1006 degrees F

(3) Body weight mdash If possible measure weight at the beginning and end of each day to see if enough fluids are being taken during the day The body water loss should not exceed 15 percent of total body weight in a work day

FOR WR GRACE amp Co - CONN M wp_DocsN099v2oooFiNALpHASFinjo22si6oowpD A I I B1-19 HSI GeoTrans inc

Prevention of heat stress can be achieved by

(1) Modification of work schedules as required by site conditions and personnel monitoring

(2) Provision of shelters or shaded areas to protect workers during rest periods

(3) Maintenance of body fluids at normal levels by drinking cold water and

(4) Training Site Personnel to recognize and treat heat stress signs

(5) Acclimation

First Aid

Bites (Animal) mdash Thoroughly wash the wound with soap and water Flush the area with running water and apply a sterile dressing Immobilize affected part until the victim has been attended by a physician See that the animal is kept alive and in quarantine Obtain name and address of the owner of the animal

Bites (Insect) ~ Remove stinger if present Keep affected part down below the level of the heart Apply ice bag For minor bites and stings apply soothing lotions such as calamine

Burns (minor) ~ Do not apply Vaseline or grease of any kind Apply cold water applications until pain subsides Cover with a dry sterile gauze dressing Do not break blisters or remove tissue Seek medical attention

Burns (severe) mdash Do not remove adhered particles of clothing Do not apply ice or immerse in cold water Do not apply ointment grease or Vaseline Cover burns with thick sterile dressings Keep burned feet or legs elevated Seek medical attention immediately

Chemical Burns ~ Wash away the chemical soaked clothing with large amounts of water Remove victims chemical soaked clothing If dry lime brush away before flushing Apply sterile dressing and seek medical attention

Terra Tech Inc Safe Work Practices Issue Date July 1998 Non-Permit-Required Confined Space Entry Practices Revision No 1 SWPNo 6-24 Page 1

NON-PERMIT-REQUIRED CONFINED SPACE ENTRY PRACTICES

The following safe work practices (SWP) apply to entry into confined spaces classified as non-permitshy

required The confined space must conform to the definition of a non-permit-required confined space as

discussed in the Confined Space Entry Program (see Document Control No 2-5 in Volume I) Entry into

spaces classified as non-permit-required are preferable over entry into permit-required spaces When

feasible efforts shall be directed to prepare confined spaces so they meet the definitions of non-permitshy

required confined space

If any of the procedures discussed in this SWP cannot be completed or an unanticipated hazard is

identified the non-permit-required status of the space will be revoked until the space is re-evaluated and

reapproved as a non-permit-required space by a technically qualified individual such as a Tetra Tech

health and safety specialist

Non-permit-required confined space entry procedures before entry into the space are listed below

bull The project manager and the site safety coordinator (SSC) should be notified of the need to enter into a confined space This notification must allow sufficient time to assemble necessary safety equipment

bull A blank Preparation and Testing of Non-Permit Required Confined Space form (Form CS-2) must be obtained (see Volume HI)

bull The necessary safety equipment can include but is not limited to atmospheric testing meters and devices a mechanical ventilator and a ladder for entry and exit

bull All equipment to be used during entry must be tested and inspected before use Atmospheric testing equipment shall be calibrated in accordance with the manufacturers instructions to ensure proper operation Calibration parameters shall be documented in the field logbook and the equipment will be tagged with a label specifying these parameters

bull Hazardous conditions associated with the removal of the entrance cover should be eliminated before opening the confined space After removal of the entrance cover the opening should be promptly barricaded by a railing temporary cover or other temporary barrier to prevent employees and equipment from accidentally falling through the opening

bull The internal atmosphere should be tested for the following conditions in the order given

Disclaimer This safe work practice (SWP) is the property of Tetra Tech Inc (Tetra Tech) and its subsidiaries Any reuse of the SWP without Terra Techs permission is at the sole nsk of the user The user will hold harmless Tetra Tech for any damages that result from unauthorized reuse of this SWP Authorized users are responsible for obtaining proper training and qualification from their employer before performing operations described in this SWP

- Oxygen content (should be between 195 to 235 percent)

- Combustible gases (should be less than 10 percent of the lower explosive limit)

- Potential toxic air contaminants

bull The space should be tested at all levels (top middle and bottom) and in all areas where work may occur The atmosphere within the space must not be hazardous whenever an employee is inside the space

bull If forced-air ventilation is used the following conditions apply

mdash Ventilation should not be used to control continuous sources of hazardous contaminants

- There must be a clean source of air that will not increase the hazard within the space

bull The entrant shall document on Form CS-2 that the space is safe for entry and that preshyentry measures required by this SWP have been taken The form shall be made available to each employee entering the space and shall be kept at the work site until completion of confined space work The certificate will then become part of the permanent project file

The atmosphere within the confined space must be tested periodically while entrants are within the

confined space Frequency of testing shall be every 30 minutes during the first 2 hours then hourly

afterwards when entrants are in the confined space If at any time during occupancy a hazardous

atmosphere is detected the entrants shall leave the space immediately The space shall then be evaluated

to determine how the hazardous atmosphere developed and measures shall be implemented to protect

employees from the hazardous atmosphere before any subsequent entry Re-entry shall not be allowed

until atmospheric testing demonstrates acceptable conditions

When changes in the use or configuration of a non-permit-required space cannot be eliminated or

controlled the SSC shall re-evaluate the space and if necessary reclassify it as a permit-required

confined space

Disclaimer This safe work practice (SWP) is the property of Tetra Tech Inc (Tetra Tech) and its subsidiaries Any reuse of the SWP without Tetra Techs permission is al the sole risk of the user The user will hold harmless Tetra Tech for any damages chat result from unauthorized reuse of this SWP Authorized users are responsible for obtaining proper training and qualification from their employer before performing operations described in this SWP

Potential Health Effects

Inhalation Corrosive Inhalation of vapors can cause coughing choking inflammation of the nose throat and upper respiratory tract and in severe cases pulmonary edema circulatory failure and death Ingestion Corrosive Swallowing hydrochloric acid can cause immediate pain and bums of the mouth throat esophagus and gastrointestinal tract May cause nausea vomiting and diarrhea Swallowing may be fatal Skin Contact Corrosive Can cause redness pain and severe skin burns Concentrated solutions cause deep ulcers and discolor skin Eye Contact Corrosive Vapors are irritating and may cause damage to the eyes Contact may cause severe burns and permanent eye damage Chronic Exposure Long-term exposure to concentrated vapors may cause erosion of teeth Long term exposures seldom occur due to the corrosive properties of the acid Aggravation of Pre-existing Conditions Persons with pre-existing skin disorders or eye disease may be more susceptible to the effects of this substance

4 First Aid Measures

Inhalation Remove to fresh air If not breathing give artificial respiration If breathing is difficult give oxygen Get medical attention immediately Ingestion DO NOT INDUCE VOMITING Give large quantities of water or milk if available Never give anything by mouth to an unconscious person Get medical attention immediately Skin Contact hi case of contact immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes Wash clothing before reuse Thoroughly clean shoes before reuse Get medical attention immediately

HYDROCHLORIC ACID 33 - 40 httpwwwjtbakercommsdsh3880htm

Eye Contact Immediately flush eyes with plenty of water for at least 15 minutes lifting lower and upper eyelids occasionally Get medical attention immediately

5 Fire Fighting Measures

Fire Extreme heat or contact with metals can release flammable hydrogen gas Explosion Not considered to be an explosion hazard Fire Extinguishing Media If involved in a fire use water spray Neutralize with soda ash or slaked lime Special Information In the event of a fire wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode Structural firefighters protective clothing is ineffective for fires involving hydrochloric acid Stay away from ends of tanks Cool tanks with water spray until well after fire is out

6 Accidental Release Measures

Ventilate area of leak or spill Wear appropriate personal protective equipment as specified in Section 8 Isolate hazard area Keep unnecessary and unprotected personnel from entering Contain and recover liquid when possible Neutralize with alkaline material (soda ash lime) then absorb with an inert material (e g vermiculite dry sand earth) and place in a chemical waste container Do not use combustible materials such as saw dust Do not flush to sewer US Regulations (CERCLA) require reporting spills and releases to soil water and air in excess of reportable quantities The toll free number for the US Coast Guard National Response Center is (800) 424-8802

J T Baker NEUTRASORB(tm) or TEAM(tm) Low Na+ acid neutralizers are recommended for spills of this product

7 Handling and Storage

Store in a cool dry ventilated storage area with acid resistant floors and good drainage Protect from physical damage Keep out of direct sunlight and away from heat water and incompatible materials Do not wash out container and use it for other purposes When diluting the acid should always be added slowly to water and in small amounts Never use hot water and never add water to the acid Water added to acid can cause uncontrolled boiling and splashing When opening metal containers use non-sparking tools because of the possibility of

mdash- hydrogen gas being present Containers of this material may be hazardous when empty since they retain product residues (vapors liquid) observe all warnings and precautions listed for the product

8 Exposure ControlsPersonal Protection

Airborne Exposure Limits -OSHA Permissible Exposure Limit (PEL) 5 ppm Ceiling -ACGIH Threshold Limit Value (TLV) 5 ppm Ceiling

Ventilation System A system of local andor general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source preventing dispersion of it into the general work area Please refer to the ACGIH document Industrial Ventilation A Manual of Recommended Practices most recent edition for details Personal Respirators (NIOSH Approved) If the exposure limit is exceeded a full facepiece respirator with an acid gas cartridge may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier whichever is lowest For emergencies or instances where the exposure levels are not known use a full-facepiece positive-pressure air-supplied respirator WARNING Air purifying respirators do not protect workers in oxygen-deficient atmospheres Skin Protection Rubber or neoprene gloves and additional protection including impervious boots apron or coveralls as needed in areas of unusual exposure to prevent skin contact Eye Protection Use chemical safety goggles andor a full face shield where splashing is possible Maintain eye wash fountain and quick-drench facilities in work area

Menzie-Cura amp Associates Addendum to the HIS Geotrans Health and Safety Plan WR Grace Superfund Site

Acton Massachusetts

Menzie-Cura amp Associates Inc adopts the HSI Geotrans Health and Safety Plan (HSP) The HSP contains a hazard assessment for contaminants found at the Site historically In addition to HSI Geotrans HSP Menzie-Cura amp Associates Inc personnel will following the boating safety procedures identified here when sampling in Sinking Pond and the reference pond

This work will take place in a small boat (possibly using a gasoline run outboard motor) All personnel will wear a United States Coast Guard approved personal flotation device (PFD) whenever working from the boat No smoking is allowed at any time in the boat or within 50 feet of it during refueling The Captain will be named at a later date At the Captains discretion he or she can modify or cancel any on-board operation for safety reasons Such reasons may include but are not limited to weather condition of boat or motor condition of sampling equipment or preparedness of personnel All personnel working on board will follow his or her orders

We will follow small boat safety procedures The boats transom or seats will contain a plate which describes the total weight capacity and other limitations of the particular boat used We will not exceed these The boats equipment will include motor full spare gasoline tank oars installed oar locks Danforth anchor 50 feet of half inch nylon anchor line terminated in three feet of half inch galvanized chain a metered and weighted line to estimate depth personal flotation devices (PFDs) for everyone on board a two quart canteen of drinking water (otherwise there should be no food on-board) and a cell phone

Personnel on board will each carry a belted and sheathed jack knife or rigging knife On-board personnel will be aware of the position of their bodies relative to coiled or faired lines or lines under tension Especially do not put hands or feet in any basket containing a faired line or sit upon a coiled deck line Always position yourself to one side of a line under tension Never position yourself behind a line under tension or between such a line and the gunnel of the boat or any other immovable object During over the side operations lower all lines Never let a weighted line free fall The most common way to drown is to go over the side with a free falling anchor or equipment line tangled around a leg arm or neck Grab samplers are not intended to free fall they are designed to be lowered It may be necessary to let certain samplers free fall a short distance (ie several feet) from above the bottom Lower them to that height above bottom Always know the depth to bottom before deploying equipment

Generally stay seated in the boat It is sometimes necessary to stand when deploying equipment Do this keeping your center of gravity as low as possible and as near the center line of the boat as possible Before standing or changing your position in the boat announce your intentions to all on-board

1 INTRODUCTION

This Health and Safety Plan (HSP) has been designed to protect the health and

safety of project personnel and the surrounding community The purpose of the plan is to

assign responsibilities establish personal protection standards and mandatory safety

practices and procedures and provide for contingencies that may arise while operations

are being conducted at the WR Grace amp Co - Conn (Grace) Acton Superfund Site (the

Site) The HSP incorporates the Occupational Health and Safety (OSHA) requirements

presented in 29 CFR Part 1910 The selection of the level of personal protective

equipment (PPE) is based on OSHA Permissible Exposure Limits (PELs) the American

Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values

(TLVs) and the National Institute for Occupational Safety and Health (NIOSH)

Recommended Exposure Limits (RELs) The Workplace Hazard Assessment

Certification required by 29 CFR Part 1910132 is provided following the signature page

for this HSP Detailed information on the HSI GeoTrans comprehensive corporate health

and safety program is contained in the Terra Tech Inc Health and Safety Manual (HSI

1123 SITE EMERGENCY PROCEDURES

FireExplosion

A fire that cannot be readily extinguished with one ten pound fire extinguisher

will be considered major and may require evacuation of Site personnel to safe areas The

SSO will call the fire department and will coordinate with fire emergency personnel as to

the selection of protective clothing and equipment as well as the use of proper fire

FOR wR GRACE amp Co - CONN M Wgt DOCSN0992000FINA1 PHASE I RIX02251600 wpo APR D1-6 HSI GeoTrans inc

fighting techniques The air downwind from any fireexplosion is to be monitored

immediately in order to protect workers and the nearby community If so required by the

air monitoring results the Vapor Emission Response Plan will be placed into effect If

personal injuries result from any fire or explosion the procedures outlined in the Personal

Injury Response Plan will be followed

Hazardous Spill

Any release or threat of release occurring during the work that constitutes an

emergency or may present an immediate threat to public health welfare or the

environment will be reported by the SSO or clients representative to the government

parties In the event of a spill the two main goals are to contain the spill as much as

possible and to minimize vapor emissions In order to accomplish these goals the

following equipment should be available at the Site

(1) an empty container

(2) polyethylene sheets

(3) absorbent materials and

(4) a shovel

Vapor Emission Response Plan

If any of the following conditions are identified at the Site exclusion zone

boundary all activities must be halted

(1) organic levels observed on air monitoring equipment of unknown

constituents are greater than 5 ppm above known background or

action levels requiring evacuation are reached or

(2) LEL levels greater than 10

If following the cessation of activities or as the result of an emergency

such as that described in the section on FireExplosion any of the above levels

persist downwind from the Site at the boundary of the exclusion zone then this

FOR W R GRACE amp Co - CONN MWP_DOCSW0992000F1NALPHASEIRI022SI600WPD APP D1-7 HSI GfiOTfanS lllC

Emergency Plan will automatically be placed into effect Upon activation of the

Emergency Plan the nearest perimeter of the closest downwind residential or

commercial property will immediately be monitored If organic levels from an

unknown source approach 5 ppm the local police authorities or property owner

will immediately be contacted by the SSO or clients representative and advised of

the situation

Personal Injury Response Plan

Accidents - Depending on the seriousness of the injury treatment may be

given at the Site by the SSO For more serious injuries additional assistance by

ambulance may be required at the Site or the victim may have to be treated at a

medical facility The SSO will assess the seriousness of the injury and will

consult by phone with a physician if necessary The SSO will file a complete

incident report with the Office Health and Safety Officer and the Project

Coordinator as soon as possible

Chemical Overexposure - Personnel including unauthorized personnel

that suffer chemical overexposure shall be treated in the following manner

bull Skin Contact Remove contaminated clothing Wash immediately with water Use soap if available

bull Inhalation Remove from contaminated atmosphere Artificial respiration if necessary Transport to hospital

bull Ingestion Never induce vomiting on an unconscious person Also never induce vomiting when acids alkalis or petroleum products are suspected Contact the poison control center

These personnel shall be observed by the SSO to ascertain whether there

are any symptoms resulting from overexposure If there is any visible

manifestation of overexposure such as skin irritation Project Personnel should be

FOR WR GRACE amp Co - CONN MWP DOCSN0992000F1NAL PHASE I RI02251600 WPD APP D1-8 HSI GeOTfanS IRC

examined by a physician All episodes of obvious chemical contamination are to

be reviewed by the SSO in order to determine whether changes are needed in

work procedures The SSO will file a complete incident report with the Office

Health and Safety Representative and the Project Coordinator as soon as possible

Radiation

Background for ionizing radiation is normally 001 to 005 mRhr

Background levels at the site that exceed these values should be listed under

background information If levels exceed background but are less than 1 mRhr

the investigation may continue with caution If levels exceed 1 mRhr all

activities must stop and personnel must evacuate the Site or portions of the Site

that exceed 1 mRhr

113 BACKGROUND INFORMATION

Overall Risk is High Moderate _

Low Unknown

1131 FACILITY DESCRIPTION

The Site is located in Acton and Concord Massachusetts on Independence Road

The Grace property is bordered by residential property on the northwest east and west

and industrial properties to the south and northeast Fort Pond Brook bounds the Grace

property to the northwest and the Assabet River bounds the Grace property to the

southeast The Assabet well field which supplies water for the Town of Acton is located

southwest of the Grace property Two inactive sand and gravel pits Massachusetts

Broken Stone Pit and Assabet Sand and Gravel are located south of the Grace property

Former occupants of the Site include American Cyanamid Company which

manufactured explosives and Dewey amp Almy Chemical Company Dewey amp Almy

acquired the property in 1946 and manufactured synthetic rubber container sealant

products An organic chemical plant which produced latex products plasticizers and

resins commenced operation in 1949 A paper battery separator production facility was

constructed in 1951

Grace acquired Dewey and Almy in 1954 and chemical operations were

continued at the Site Grace produced materials used to make concrete and organic

chemicals container sealing compounds latex products and paper and plastic battery

separators Wastewater and solid industrial wastes from these operations were disposed

in several on-site lagoons and an on-site landfill In addition the by-products of some

chemical processes were disposed of in the Slowdown Pit located in the central portion of

the property (Figure 1-2) Discharge to these areas ceased in 1980 Production of organic

chemicals was discontinued in 1982 A small distribution center for concrete additives

(Grace Construction Products) was moved to another location in September 1996 A

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINAL PHASE I RI022S1600 WPD APPD1-11 HSI GeOTianS lllC

second battery separator plant (Daramic) was constructed in 1979 and operations there

continued until 1991 The Daramic facility has not been considered part of the Site All

buildings with the exception of the building associated with the ARS have been

demolished

In 1978 groundwater contamination consisting mainly of 11-dichloroethene

(VDC) and lesser amounts of vinyl chloride ethylbenzene and benzene was detected in

two Acton municipal supply wells Assabet 1 and Assabet 2 located southwest of the

Grace property This discovery prompted a series of investigations which culminated in

the installation of the ARS beginning in late 1983 The ARS is a network of eleven

extraction wells designed to contain and cleanup contaminated groundwater and it is

currently operational

Following installation of the ARS extensive investigations were done by Grace

on in beneath and immediately surrounding the source areas to determine the nature and

extent of contamination by waste disposal practices Following a complete engineering

analysis of cleanup and remedial alternatives for the sources referred to as Operable

Unit-1 (OU-1) a remedy was selected for OU-1 Implementation of the remedy began in

November 1994 and was completed in July 1997 Following completion of the OU-1

remedy a comprehensive review of the groundwater quality and groundwater flow

conditions observed at the Site since the early 1980s and an evaluation of the

effectiveness of the ARS to contain and remediate groundwater affected by the Site was

done in the Initial Site Characterization Report (ISCR) (HSI GeoTrans 1998) While

data reviewed in the ISCR indicated that most areas of the Site containing groundwater

contamination are within the ARS capture zone and that contaminant concentrations in

most wells located outside of the capture zone have decreased significantly since 1984

uncertainties remain regarding the flow of groundwater and the distribution of

contaminants in certain areas of the Site The RIFS is designed to evaluate the extent of

FOR WR GRACE amp Co - CONN M wp_DocsN0992ooofiNALpnASEiRno225i6oowpo APPD1-12 HSI GeoTrans inc

groundwater contamination on- and off-Site and to determine whether additional remedial

measures are necessary to ensure accelerated restoration of the groundwater affected by

the Site to a fully usable condition

The Site property is now inactive as a manufacturing center The perimeter is

identified but due to the size is not secured Access to the Site is controlled through

locked gated entrances and exits The surrounding area is heavily wooded and restricts

the entrance of vehicles to the Site

1132 EXISTING CHEMICAL DATA

The existing historical chemical data for the Site has been compiled through a

thorough review of past activities at the Site and a review of the Site electronic database

For the purposes of this HSP only data collected after the completion of the source

removal activities will be used to evaluate health and safety concerns at the Site The

electronic database was queried in March of 1999 to determine the maximum

concentration and frequency of compounds detected in groundwater at the Site since

January 1 1996 (Table 1-1)

The volatile organic compounds (VOCs) with the highest frequency of detections

and maximum detection shown in parentheses at the Site are benzene (8600 ugL)

VDC (1000 ugL) and vinyl chloride (280 ugL) The semi-volatile organic compounds

(SVOCs) with the highest frequency of detections and maximum detection shown in

parenthesis at the Site are diethlyphthalate (110 ugL) bis(2-ethylhexyl)phthalate (120

ugL) and bis(2- chloroethyl)ether (41 ugL) The inorganic compounds with the highest

frequency of detections and maximum detection shown in parenthesis at the Site are

arsenic (13000 ugL) aluminum (42000 yUgL) nickel (890 ugL) and cadmium (16

ugL) The groundwater data collected indicate that pesticides and PCBs are not a

concern at the Site (HSI GeoTrans 1998) Therefore no pesticides or PCBs will be

monitored for during work tasks at the Site

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINM PHASE I RI0225I600 wro APPD1-13 HSI GeOTfanS lllC

Other compounds have been detected at varying concentrations and at a wide

range of frequencies at the Site Because such a wide range of VOCs SVOCs and

inorganics have been detected at the Site it was necessary to screen these compounds for

potential health hazards and exposure risks A full discussion of the potential health

hazard and exposure risk screening is provided in Attachment A Attachment A also

includes tables which indicate the physical description and associated health hazards for

each compound detected at the Site (Attachment A Table A-l) the exposure limits and

monitoring properties for each compound detected at the Site (Attachment A Table A-2)

compounds with gas and vapor exposure limits less than 5 ppm (Attachment A Table Ashy

3) compounds with particulate exposure limits less than 1 mgm3 (Attachment A Table

A-4) and a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) (Attachment A Table A-5)

Based on the screening discussed in Attachment A it was determined that the

compounds listed in Table 1-2 are contaminants of monitoring concern These

compounds have vapor exposure limits less than 5 ppm have been detected at least four

times and have a maximum detection concentration greater than 10 ppb (ugL) The

compounds found at the highest frequency and with greatest maximum concentration at

the Site benzene VDC and vinyl chloride are included in the list of compounds of

monitoring concern and comprise the lowest exposure limits Therefore benzene VDC

and vinyl chloride will be used as indicator compounds for vapor monitoring during work

tasks No dust monitoring will be conducted Work practices and investigation derived

waste (IDW) management practices will be used that will minimize the potential for

contaminated soil to be suspended in breathing space air Because vapor monitoring

action levels are lower than LEL action levels (10 percent of the LEL) no LEL

monitoring is required aside from that associated with confined space entry of the

recovery well vaults

POTENTIAL HEALTH HAZARD AND EXPOSURE RISK SCREENING

FOR WR GRACE amp Co - CONN M wp_Docswo992oooFiNALpiiASE i wo225 i6oo wro ATTA1-1 HSI GeoTrans inc

POTENTIAL HEALTH HAZARD AND EXPOSURE RISK SCREENING

The historical chemical data for the Site has been compiled through a thorough

review of past activities at the Site and a review of the Site electronic database For the

purposes of this HSP only data collected after the completion of the source removal

activities will be used to evaluate health and safety concerns at the Site The electronic

database was queried in March of 1999 to determine the maximum concentration and

frequency of compounds detected in groundwater at the Site since January 1 1996 (see

Table 1-1)

A hazard screening evaluation was performed for each compound identified in the

database search described above Table A-l indicates the associated health hazards

(exposure routes symptoms and target organs) for compounds detected at the Site and

the physical description (eg color solidliquidgas phase odor) Compounds for which

the NIOSH guide (NIOSH 1998) did not contain health hazard or physical description

information are shown with no information in the table row Some physical descriptions

for compounds were gathered from other sources (See Table A-l citation notes)

Table A-2 provides the exposure limits a summary of daily time weighted

average (Per Day TWA) and the 15 minute short term (15 min STEL) ceiling and

immediately dangerous to life or health (IDLH) exposure limits The limits shown are the

most stringent quantified exposure limits put forth by OSHA NIOSH and ACGIH for

each exposure limit category

Compounds that NIOSH considers to be potential occupational carcinogens are

designated with a check in the CA box in Tables A-2 A-3 and A-4 NIOSH usually

recommends that occupational exposures to carcinogens be limited to the lowest feasible

concentration (LFC) Those compounds NIOSH has identified as potential carcinogens

but has not quantified recommended exposure limits (REL) are designated with LFC

under the Most Stringent Exposure Limit column in Attachment A Table A-3 The

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINA1 PHASE I RT02251600 WPD ATT A1 -2 HSI GeOTiaHS lllC

ACGIH has categorized compounds into five carcinogenicity groups based on available

information Al for confirmed human carcinogens A2 for suspected human carcinogens

A3 for confirmed animal carcinogen with unknown relevance to humans A4 for not

classifiable as a human carcinogen and A5 for compounds not suspected as a human

carcinogen The carcinogenicity category for compounds which ACGIH has designated

is also shown in Tables A-2 A-3 and A-4

The compounds that have potential air monitoring concerns for this Site are those

compounds designated in Table A-3 with LFC an ACGIH carcinogenicity of Al or A2

a gas and vapor exposure limit of 5 ppm or less or with a suspended-in-air particulate

exposure limit of 1 mgm3 or less Tables A-3 and A-4 summarize the most stringent gas

and vapor and particulate exposure limits for these compounds respectively

The compounds with gas and vapor exposure limits of 5 ppm or less which were

detected at low frequency and low concentration (three or fewer times and at a

concentration less than 10 ppb (^gL)) are not considered to be of monitoring concern

(Table A-3) The remaining compounds in Table A-3 have only been detected at

locations where the concentration of benzene VDC and vinyl chloride represent the

majority of the total concentration of chemicals with monitoring concerns Because the

exposure limits for benzene VDC and vinyl chloride are low and these compounds make

up the majority of contamination in groundwater at the Site monitoring for benzene

VDC and vinyl chloride is a conservative means to evaluate work task exposure risks

which establish action level PPE modifications In order to screen for the compounds in

Table A-3 detector tubes or other compound specific monitoring devices for the indicator

parameters (benzene VDC and vinyl chloride) will be used according to action levels

associated with the tasks to be performed

The compounds with a suspended-in-air particulate exposure limit of 1 mgm3 or

less which were detected at low frequency and low concentration (three or fewer times

and at a concentration less than 10 ppb (^gL)) are not considered to be of monitoring

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FlNALPHAbElRI02251600 WO ATTA1-3 HSI GCOTfanS 1HC

concern (Table A-4) Work practices and investigation derived waste (1DW)

management practices will be used that will minimize the potential for contaminated soil

to be suspended in breathing space air above the exposure levels for the remaining

compounds

Table A-5 is a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) Because vapor monitoring action

levels are lower than LEL action levels (10 percent of the LEL) no LEL monitoring is

required

PERSONAL INJURY RESPONSE PLAN

Accidents

Physical injuries can range from a sprained ankle to a compound fracture or from a

minor cut to massive bleeding Depending on the seriousness of the injury treatment

may be given at the site by the Site Safety Officer For more serious injuries additional

assistance by ambulance may be required at the site or the victim may have to be treated

at a medical facility The Safety Officer will assess the seriousness of the injury and will

consult by phone with a physician if necessary

Chemical Exposure

Personnel including unauthorized personnel that suffer chemical overexposure shall

be treated in the following manner

bull Skin Contact Remove contaminated clothing Wash immediately with water Use soap if available

bull Inhalation Remove from contaminated atmosphere Artificial respiration is necessary Transport to hospital

bull Ingestion Never induce vomiting on an unconscious person Also never induce vomiting when acids alkalis or petroleum products are suspected Contact the poison control center

bull Ionizing Radiation Normal background 001 to 005 mRhr If less than 1 mRhr continue investigation with caution If greater than 1 mRhr evacuate site

These personnel shall be observed by the Site Safety Officer to ascertain whether

there are any symptoms resulting from overexposure If there is any visible manifestation

of overexposure such as skin irritation Project Personnel should be examined by a

physician All episodes of obvious chemical contamination are to be reviewed by the Site

Safety Officer in order to determine whether changes are needed in work procedures

Cold Stress

Persons working outdoors in temperatures at or below freezing may be frostbitten

Exposure to extreme cold for a short time may cause severe injury to the surface of the

body or result in profound generalized cooling causing death Areas of the body that

have a high surface-area-to-volume ratio such as fingers toes and ears are the most

susceptible Two factors influence the development of a cold injury ambient temperature

and the velocity of the wind Wind chill is used to describe the chilling effect of moving

air in combination with low temperature For instance 10degF with a wind of 15 mph is

equivalent in chilling effect to still air at -18degF

As a general rule the greatest incremental increase in wind chill occurs when a wind

of 5 mph increases to 10 mph Additionally water conducts heat 240 times faster than

air Thus the body cools suddenly when chemical-protective equipment is removed if the

clothing underneath is soaked with perspiration Local injury resulting from cold is

included in the generic term frostbite There are several degrees of damage

Systemic hypothermia is caused by exposure to freezing or rapidly dropping

temperature Its symptoms are usually exhibited in five stages (1) shivering (2) apathy

listlessness sleepiness and (sometimes) rapid cooling of the body to less than 95 degF (3)

unconsciousness glassy stare slow pulse and slow respiratory rate (4) freezing of the

extremities and finally (5) death

Prevention of Cold Stress can be achieved by (1) Modification of work schedules as

required by site conditions and personnel monitoring (2) Provision of shelters to protect

workers during rest periods (3) Maintenance of body heat at normal levels by wearing

adequate layers of clothing (4) Training site personnel to recognize and treat cold stress

(5) Frequent warm up breaks (6) Acclimation

Heat Stress

Wearing personal protective equipment puts a field worker at considerable risk of

developing heat stress This can result in health effects ranging from transient heat

fatigue to serious illness or death Heat stress is an aggregate of all the heat factors both

internal and external that work on the body

FOR WR GRACE amp Co - CONN MWP_DOCSNON2000F[NALP11ASEIRI0225600WPO ATT B1-18 HSI GCOTfanS IHC

External factors that contribute to heat stress include ambient air temperature

radiant temperature air velocity and the relative humidity Internal factors include

metabolic heat body core temperature respiration rate and acclimation

Early symptoms of heat stress include mental confusion and the inability to

concentrate heat rash and heat cramps (muscle spasms andor pain in hands feet and

abdomen) Acute and chronic heat stress impacts a workers temperament causing

impulsive aggressive and violent acts to be committed by the victim Signs of heat

exhaustion include pale cool moist skin heavy sweating dizziness nausea and fainting

Heat stroke is the most serious form of heat stress Immediate action must be taken to

cool the body and prevent serious injury Competent medical help must be obtained

Signs include red hot dry skin lack of or reduced perspiration nausea dizziness and

confusion strong rapid pulse and coma The case-fatality of heat-stroke and heat

exhaustion is probably no lower than 10 percent Because heat stress is one of the most

common (and potentially serious) illnesses at field sites regular monitoring and other

preventative precautions are vital

To monitor for heat stress measure

(1) Heart rate mdash Count the radial pulse during a 30-second period as early as possible during rest periods If the heart exceeds 110 beats per minute at the beginning of the rest period shorten the next work cycle by one-third and keep the rest period the same If the heart rate still exceeds 110 beats per minute at the next rest period shorten the following work cycle by one-third again

(2) Oral temperatures mdash Use an oral thermometer to measure the oral temperature at the end of the work period (before drinking) If oral temperature exceeds 996 degrees F shorten the next work cycle by one-third without changing the rest period Repeat if necessary Do not permit a worker to wear PPE when the workers oral temperature is above 1006 degrees F

(3) Body weight mdash If possible measure weight at the beginning and end of each day to see if enough fluids are being taken during the day The body water loss should not exceed 15 percent of total body weight in a work day

FOR WR GRACE amp Co - CONN M wp_DocsN099v2oooFiNALpHASFinjo22si6oowpD A I I B1-19 HSI GeoTrans inc

Prevention of heat stress can be achieved by

(1) Modification of work schedules as required by site conditions and personnel monitoring

(2) Provision of shelters or shaded areas to protect workers during rest periods

(3) Maintenance of body fluids at normal levels by drinking cold water and

(4) Training Site Personnel to recognize and treat heat stress signs

(5) Acclimation

Terra Tech Inc Safe Work Practices Issue Date July 1998 Non-Permit-Required Confined Space Entry Practices Revision No 1 SWPNo 6-24 Page 1

NON-PERMIT-REQUIRED CONFINED SPACE ENTRY PRACTICES

The following safe work practices (SWP) apply to entry into confined spaces classified as non-permitshy

required The confined space must conform to the definition of a non-permit-required confined space as

discussed in the Confined Space Entry Program (see Document Control No 2-5 in Volume I) Entry into

spaces classified as non-permit-required are preferable over entry into permit-required spaces When

feasible efforts shall be directed to prepare confined spaces so they meet the definitions of non-permitshy

required confined space

If any of the procedures discussed in this SWP cannot be completed or an unanticipated hazard is

identified the non-permit-required status of the space will be revoked until the space is re-evaluated and

reapproved as a non-permit-required space by a technically qualified individual such as a Tetra Tech

health and safety specialist

Non-permit-required confined space entry procedures before entry into the space are listed below

bull The project manager and the site safety coordinator (SSC) should be notified of the need to enter into a confined space This notification must allow sufficient time to assemble necessary safety equipment

bull A blank Preparation and Testing of Non-Permit Required Confined Space form (Form CS-2) must be obtained (see Volume HI)

bull The necessary safety equipment can include but is not limited to atmospheric testing meters and devices a mechanical ventilator and a ladder for entry and exit

bull All equipment to be used during entry must be tested and inspected before use Atmospheric testing equipment shall be calibrated in accordance with the manufacturers instructions to ensure proper operation Calibration parameters shall be documented in the field logbook and the equipment will be tagged with a label specifying these parameters

bull Hazardous conditions associated with the removal of the entrance cover should be eliminated before opening the confined space After removal of the entrance cover the opening should be promptly barricaded by a railing temporary cover or other temporary barrier to prevent employees and equipment from accidentally falling through the opening

bull The internal atmosphere should be tested for the following conditions in the order given

Disclaimer This safe work practice (SWP) is the property of Tetra Tech Inc (Tetra Tech) and its subsidiaries Any reuse of the SWP without Terra Techs permission is at the sole nsk of the user The user will hold harmless Tetra Tech for any damages that result from unauthorized reuse of this SWP Authorized users are responsible for obtaining proper training and qualification from their employer before performing operations described in this SWP

Tetra Tech Inc Safe Work Practices Issue Date July 1998 Non-Permit-Required Confined Space Entry Practices Revision No 1 SWPNo 6-24 Page 2

- Oxygen content (should be between 195 to 235 percent)

- Combustible gases (should be less than 10 percent of the lower explosive limit)

- Potential toxic air contaminants

bull The space should be tested at all levels (top middle and bottom) and in all areas where work may occur The atmosphere within the space must not be hazardous whenever an employee is inside the space

bull If forced-air ventilation is used the following conditions apply

mdash Ventilation should not be used to control continuous sources of hazardous contaminants

- There must be a clean source of air that will not increase the hazard within the space

bull The entrant shall document on Form CS-2 that the space is safe for entry and that preshyentry measures required by this SWP have been taken The form shall be made available to each employee entering the space and shall be kept at the work site until completion of confined space work The certificate will then become part of the permanent project file

The atmosphere within the confined space must be tested periodically while entrants are within the

confined space Frequency of testing shall be every 30 minutes during the first 2 hours then hourly

afterwards when entrants are in the confined space If at any time during occupancy a hazardous

atmosphere is detected the entrants shall leave the space immediately The space shall then be evaluated

to determine how the hazardous atmosphere developed and measures shall be implemented to protect

employees from the hazardous atmosphere before any subsequent entry Re-entry shall not be allowed

until atmospheric testing demonstrates acceptable conditions

When changes in the use or configuration of a non-permit-required space cannot be eliminated or

controlled the SSC shall re-evaluate the space and if necessary reclassify it as a permit-required

confined space

Disclaimer This safe work practice (SWP) is the property of Tetra Tech Inc (Tetra Tech) and its subsidiaries Any reuse of the SWP without Tetra Techs permission is al the sole risk of the user The user will hold harmless Tetra Tech for any damages chat result from unauthorized reuse of this SWP Authorized users are responsible for obtaining proper training and qualification from their employer before performing operations described in this SWP

Potential Health Effects

Inhalation Corrosive Inhalation of vapors can cause coughing choking inflammation of the nose throat and upper respiratory tract and in severe cases pulmonary edema circulatory failure and death Ingestion Corrosive Swallowing hydrochloric acid can cause immediate pain and bums of the mouth throat esophagus and gastrointestinal tract May cause nausea vomiting and diarrhea Swallowing may be fatal Skin Contact Corrosive Can cause redness pain and severe skin burns Concentrated solutions cause deep ulcers and discolor skin Eye Contact Corrosive Vapors are irritating and may cause damage to the eyes Contact may cause severe burns and permanent eye damage Chronic Exposure Long-term exposure to concentrated vapors may cause erosion of teeth Long term exposures seldom occur due to the corrosive properties of the acid Aggravation of Pre-existing Conditions Persons with pre-existing skin disorders or eye disease may be more susceptible to the effects of this substance

4 First Aid Measures

Inhalation Remove to fresh air If not breathing give artificial respiration If breathing is difficult give oxygen Get medical attention immediately Ingestion DO NOT INDUCE VOMITING Give large quantities of water or milk if available Never give anything by mouth to an unconscious person Get medical attention immediately Skin Contact hi case of contact immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes Wash clothing before reuse Thoroughly clean shoes before reuse Get medical attention immediately

Eye Contact Immediately flush eyes with plenty of water for at least 15 minutes lifting lower and upper eyelids occasionally Get medical attention immediately

5 Fire Fighting Measures

Fire Extreme heat or contact with metals can release flammable hydrogen gas Explosion Not considered to be an explosion hazard Fire Extinguishing Media If involved in a fire use water spray Neutralize with soda ash or slaked lime Special Information In the event of a fire wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode Structural firefighters protective clothing is ineffective for fires involving hydrochloric acid Stay away from ends of tanks Cool tanks with water spray until well after fire is out

6 Accidental Release Measures

Ventilate area of leak or spill Wear appropriate personal protective equipment as specified in Section 8 Isolate hazard area Keep unnecessary and unprotected personnel from entering Contain and recover liquid when possible Neutralize with alkaline material (soda ash lime) then absorb with an inert material (e g vermiculite dry sand earth) and place in a chemical waste container Do not use combustible materials such as saw dust Do not flush to sewer US Regulations (CERCLA) require reporting spills and releases to soil water and air in excess of reportable quantities The toll free number for the US Coast Guard National Response Center is (800) 424-8802

J T Baker NEUTRASORB(tm) or TEAM(tm) Low Na+ acid neutralizers are recommended for spills of this product

7 Handling and Storage

Store in a cool dry ventilated storage area with acid resistant floors and good drainage Protect from physical damage Keep out of direct sunlight and away from heat water and incompatible materials Do not wash out container and use it for other purposes When diluting the acid should always be added slowly to water and in small amounts Never use hot water and never add water to the acid Water added to acid can cause uncontrolled boiling and splashing When opening metal containers use non-sparking tools because of the possibility of

mdash- hydrogen gas being present Containers of this material may be hazardous when empty since they retain product residues (vapors liquid) observe all warnings and precautions listed for the product

8 Exposure ControlsPersonal Protection

Airborne Exposure Limits -OSHA Permissible Exposure Limit (PEL) 5 ppm Ceiling -ACGIH Threshold Limit Value (TLV) 5 ppm Ceiling

Ventilation System A system of local andor general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source preventing dispersion of it into the general work area Please refer to the ACGIH document Industrial Ventilation A Manual of Recommended Practices most recent edition for details Personal Respirators (NIOSH Approved) If the exposure limit is exceeded a full facepiece respirator with an acid gas cartridge may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier whichever is lowest For emergencies or instances where the exposure levels are not known use a full-facepiece positive-pressure air-supplied respirator WARNING Air purifying respirators do not protect workers in oxygen-deficient atmospheres Skin Protection Rubber or neoprene gloves and additional protection including impervious boots apron or coveralls as needed in areas of unusual exposure to prevent skin contact Eye Protection Use chemical safety goggles andor a full face shield where splashing is possible Maintain eye wash fountain and quick-drench facilities in work area

Menzie-Cura amp Associates Addendum to the HIS Geotrans Health and Safety Plan WR Grace Superfund Site

Acton Massachusetts

Menzie-Cura amp Associates Inc adopts the HSI Geotrans Health and Safety Plan (HSP) The HSP contains a hazard assessment for contaminants found at the Site historically In addition to HSI Geotrans HSP Menzie-Cura amp Associates Inc personnel will following the boating safety procedures identified here when sampling in Sinking Pond and the reference pond

This work will take place in a small boat (possibly using a gasoline run outboard motor) All personnel will wear a United States Coast Guard approved personal flotation device (PFD) whenever working from the boat No smoking is allowed at any time in the boat or within 50 feet of it during refueling The Captain will be named at a later date At the Captains discretion he or she can modify or cancel any on-board operation for safety reasons Such reasons may include but are not limited to weather condition of boat or motor condition of sampling equipment or preparedness of personnel All personnel working on board will follow his or her orders

We will follow small boat safety procedures The boats transom or seats will contain a plate which describes the total weight capacity and other limitations of the particular boat used We will not exceed these The boats equipment will include motor full spare gasoline tank oars installed oar locks Danforth anchor 50 feet of half inch nylon anchor line terminated in three feet of half inch galvanized chain a metered and weighted line to estimate depth personal flotation devices (PFDs) for everyone on board a two quart canteen of drinking water (otherwise there should be no food on-board) and a cell phone

Personnel on board will each carry a belted and sheathed jack knife or rigging knife On-board personnel will be aware of the position of their bodies relative to coiled or faired lines or lines under tension Especially do not put hands or feet in any basket containing a faired line or sit upon a coiled deck line Always position yourself to one side of a line under tension Never position yourself behind a line under tension or between such a line and the gunnel of the boat or any other immovable object During over the side operations lower all lines Never let a weighted line free fall The most common way to drown is to go over the side with a free falling anchor or equipment line tangled around a leg arm or neck Grab samplers are not intended to free fall they are designed to be lowered It may be necessary to let certain samplers free fall a short distance (ie several feet) from above the bottom Lower them to that height above bottom Always know the depth to bottom before deploying equipment

Generally stay seated in the boat It is sometimes necessary to stand when deploying equipment Do this keeping your center of gravity as low as possible and as near the center line of the boat as possible Before standing or changing your position in the boat announce your intentions to all on-board

1 INTRODUCTION

This Health and Safety Plan (HSP) has been designed to protect the health and

safety of project personnel and the surrounding community The purpose of the plan is to

assign responsibilities establish personal protection standards and mandatory safety

practices and procedures and provide for contingencies that may arise while operations

are being conducted at the WR Grace amp Co - Conn (Grace) Acton Superfund Site (the

Site) The HSP incorporates the Occupational Health and Safety (OSHA) requirements

presented in 29 CFR Part 1910 The selection of the level of personal protective

equipment (PPE) is based on OSHA Permissible Exposure Limits (PELs) the American

Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values

(TLVs) and the National Institute for Occupational Safety and Health (NIOSH)

Recommended Exposure Limits (RELs) The Workplace Hazard Assessment

Certification required by 29 CFR Part 1910132 is provided following the signature page

for this HSP Detailed information on the HSI GeoTrans comprehensive corporate health

and safety program is contained in the Terra Tech Inc Health and Safety Manual (HSI

GeoTrans is a wholly owned subsidiary of Tetra Tech) Included in this manual is

information on corporate programs including the Health and Safety Audit Program

(Volume 1 Section 1-3) and the Personnel Protective Equipment Program (Volume 1

Section 2-7)

The provisions of the HSP are mandatory for all on-Site HSI GeoTrans

employees They set forth minimum requirements for other contractors involved in the

field activities For contamination investigations it is required that each field contractor

provide a HSP for its employees covering any exposure to hazardous materials and

complete all work in accordance with that plan HSI GeoTrans maintains no

responsibility whatsoever for the safety and welfare of any on-Site personnel except for

their own employees

1123 SITE EMERGENCY PROCEDURES

FireExplosion

A fire that cannot be readily extinguished with one ten pound fire extinguisher

will be considered major and may require evacuation of Site personnel to safe areas The

SSO will call the fire department and will coordinate with fire emergency personnel as to

the selection of protective clothing and equipment as well as the use of proper fire

FOR wR GRACE amp Co - CONN M Wgt DOCSN0992000FINA1 PHASE I RIX02251600 wpo APR D1-6 HSI GeoTrans inc

fighting techniques The air downwind from any fireexplosion is to be monitored

immediately in order to protect workers and the nearby community If so required by the

air monitoring results the Vapor Emission Response Plan will be placed into effect If

personal injuries result from any fire or explosion the procedures outlined in the Personal

Injury Response Plan will be followed

Hazardous Spill

Any release or threat of release occurring during the work that constitutes an

emergency or may present an immediate threat to public health welfare or the

environment will be reported by the SSO or clients representative to the government

parties In the event of a spill the two main goals are to contain the spill as much as

possible and to minimize vapor emissions In order to accomplish these goals the

following equipment should be available at the Site

(1) an empty container

(2) polyethylene sheets

(3) absorbent materials and

(4) a shovel

Vapor Emission Response Plan

If any of the following conditions are identified at the Site exclusion zone

boundary all activities must be halted

(1) organic levels observed on air monitoring equipment of unknown

constituents are greater than 5 ppm above known background or

action levels requiring evacuation are reached or

(2) LEL levels greater than 10

If following the cessation of activities or as the result of an emergency

such as that described in the section on FireExplosion any of the above levels

persist downwind from the Site at the boundary of the exclusion zone then this

FOR W R GRACE amp Co - CONN MWP_DOCSW0992000F1NALPHASEIRI022SI600WPD APP D1-7 HSI GfiOTfanS lllC

Emergency Plan will automatically be placed into effect Upon activation of the

Emergency Plan the nearest perimeter of the closest downwind residential or

commercial property will immediately be monitored If organic levels from an

unknown source approach 5 ppm the local police authorities or property owner

will immediately be contacted by the SSO or clients representative and advised of

the situation

Personal Injury Response Plan

Accidents - Depending on the seriousness of the injury treatment may be

given at the Site by the SSO For more serious injuries additional assistance by

ambulance may be required at the Site or the victim may have to be treated at a

medical facility The SSO will assess the seriousness of the injury and will

consult by phone with a physician if necessary The SSO will file a complete

incident report with the Office Health and Safety Officer and the Project

Coordinator as soon as possible

Chemical Overexposure - Personnel including unauthorized personnel

that suffer chemical overexposure shall be treated in the following manner

bull Skin Contact Remove contaminated clothing Wash immediately with water Use soap if available

bull Inhalation Remove from contaminated atmosphere Artificial respiration if necessary Transport to hospital

bull Ingestion Never induce vomiting on an unconscious person Also never induce vomiting when acids alkalis or petroleum products are suspected Contact the poison control center

These personnel shall be observed by the SSO to ascertain whether there

are any symptoms resulting from overexposure If there is any visible

manifestation of overexposure such as skin irritation Project Personnel should be

FOR WR GRACE amp Co - CONN MWP DOCSN0992000F1NAL PHASE I RI02251600 WPD APP D1-8 HSI GeOTfanS IRC

examined by a physician All episodes of obvious chemical contamination are to

be reviewed by the SSO in order to determine whether changes are needed in

work procedures The SSO will file a complete incident report with the Office

Health and Safety Representative and the Project Coordinator as soon as possible

Radiation

Background for ionizing radiation is normally 001 to 005 mRhr

Background levels at the site that exceed these values should be listed under

background information If levels exceed background but are less than 1 mRhr

the investigation may continue with caution If levels exceed 1 mRhr all

activities must stop and personnel must evacuate the Site or portions of the Site

that exceed 1 mRhr

113 BACKGROUND INFORMATION

Overall Risk is High Moderate _

Low Unknown

1131 FACILITY DESCRIPTION

The Site is located in Acton and Concord Massachusetts on Independence Road

The Grace property is bordered by residential property on the northwest east and west

and industrial properties to the south and northeast Fort Pond Brook bounds the Grace

property to the northwest and the Assabet River bounds the Grace property to the

southeast The Assabet well field which supplies water for the Town of Acton is located

southwest of the Grace property Two inactive sand and gravel pits Massachusetts

Broken Stone Pit and Assabet Sand and Gravel are located south of the Grace property

Former occupants of the Site include American Cyanamid Company which

manufactured explosives and Dewey amp Almy Chemical Company Dewey amp Almy

acquired the property in 1946 and manufactured synthetic rubber container sealant

products An organic chemical plant which produced latex products plasticizers and

resins commenced operation in 1949 A paper battery separator production facility was

constructed in 1951

Grace acquired Dewey and Almy in 1954 and chemical operations were

continued at the Site Grace produced materials used to make concrete and organic

chemicals container sealing compounds latex products and paper and plastic battery

separators Wastewater and solid industrial wastes from these operations were disposed

in several on-site lagoons and an on-site landfill In addition the by-products of some

chemical processes were disposed of in the Slowdown Pit located in the central portion of

the property (Figure 1-2) Discharge to these areas ceased in 1980 Production of organic

chemicals was discontinued in 1982 A small distribution center for concrete additives

(Grace Construction Products) was moved to another location in September 1996 A

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINAL PHASE I RI022S1600 WPD APPD1-11 HSI GeOTianS lllC

second battery separator plant (Daramic) was constructed in 1979 and operations there

continued until 1991 The Daramic facility has not been considered part of the Site All

buildings with the exception of the building associated with the ARS have been

demolished

In 1978 groundwater contamination consisting mainly of 11-dichloroethene

(VDC) and lesser amounts of vinyl chloride ethylbenzene and benzene was detected in

two Acton municipal supply wells Assabet 1 and Assabet 2 located southwest of the

Grace property This discovery prompted a series of investigations which culminated in

the installation of the ARS beginning in late 1983 The ARS is a network of eleven

extraction wells designed to contain and cleanup contaminated groundwater and it is

currently operational

Following installation of the ARS extensive investigations were done by Grace

on in beneath and immediately surrounding the source areas to determine the nature and

extent of contamination by waste disposal practices Following a complete engineering

analysis of cleanup and remedial alternatives for the sources referred to as Operable

Unit-1 (OU-1) a remedy was selected for OU-1 Implementation of the remedy began in

November 1994 and was completed in July 1997 Following completion of the OU-1

remedy a comprehensive review of the groundwater quality and groundwater flow

conditions observed at the Site since the early 1980s and an evaluation of the

effectiveness of the ARS to contain and remediate groundwater affected by the Site was

done in the Initial Site Characterization Report (ISCR) (HSI GeoTrans 1998) While

data reviewed in the ISCR indicated that most areas of the Site containing groundwater

contamination are within the ARS capture zone and that contaminant concentrations in

most wells located outside of the capture zone have decreased significantly since 1984

uncertainties remain regarding the flow of groundwater and the distribution of

contaminants in certain areas of the Site The RIFS is designed to evaluate the extent of

FOR WR GRACE amp Co - CONN M wp_DocsN0992ooofiNALpnASEiRno225i6oowpo APPD1-12 HSI GeoTrans inc

groundwater contamination on- and off-Site and to determine whether additional remedial

measures are necessary to ensure accelerated restoration of the groundwater affected by

the Site to a fully usable condition

The Site property is now inactive as a manufacturing center The perimeter is

identified but due to the size is not secured Access to the Site is controlled through

locked gated entrances and exits The surrounding area is heavily wooded and restricts

the entrance of vehicles to the Site

1132 EXISTING CHEMICAL DATA

The existing historical chemical data for the Site has been compiled through a

thorough review of past activities at the Site and a review of the Site electronic database

For the purposes of this HSP only data collected after the completion of the source

removal activities will be used to evaluate health and safety concerns at the Site The

electronic database was queried in March of 1999 to determine the maximum

concentration and frequency of compounds detected in groundwater at the Site since

January 1 1996 (Table 1-1)

The volatile organic compounds (VOCs) with the highest frequency of detections

and maximum detection shown in parentheses at the Site are benzene (8600 ugL)

VDC (1000 ugL) and vinyl chloride (280 ugL) The semi-volatile organic compounds

(SVOCs) with the highest frequency of detections and maximum detection shown in

parenthesis at the Site are diethlyphthalate (110 ugL) bis(2-ethylhexyl)phthalate (120

ugL) and bis(2- chloroethyl)ether (41 ugL) The inorganic compounds with the highest

frequency of detections and maximum detection shown in parenthesis at the Site are

arsenic (13000 ugL) aluminum (42000 yUgL) nickel (890 ugL) and cadmium (16

ugL) The groundwater data collected indicate that pesticides and PCBs are not a

concern at the Site (HSI GeoTrans 1998) Therefore no pesticides or PCBs will be

monitored for during work tasks at the Site

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINM PHASE I RI0225I600 wro APPD1-13 HSI GeOTfanS lllC

Other compounds have been detected at varying concentrations and at a wide

range of frequencies at the Site Because such a wide range of VOCs SVOCs and

inorganics have been detected at the Site it was necessary to screen these compounds for

potential health hazards and exposure risks A full discussion of the potential health

hazard and exposure risk screening is provided in Attachment A Attachment A also

includes tables which indicate the physical description and associated health hazards for

each compound detected at the Site (Attachment A Table A-l) the exposure limits and

monitoring properties for each compound detected at the Site (Attachment A Table A-2)

compounds with gas and vapor exposure limits less than 5 ppm (Attachment A Table Ashy

3) compounds with particulate exposure limits less than 1 mgm3 (Attachment A Table

A-4) and a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) (Attachment A Table A-5)

Based on the screening discussed in Attachment A it was determined that the

compounds listed in Table 1-2 are contaminants of monitoring concern These

compounds have vapor exposure limits less than 5 ppm have been detected at least four

times and have a maximum detection concentration greater than 10 ppb (ugL) The

compounds found at the highest frequency and with greatest maximum concentration at

the Site benzene VDC and vinyl chloride are included in the list of compounds of

monitoring concern and comprise the lowest exposure limits Therefore benzene VDC

and vinyl chloride will be used as indicator compounds for vapor monitoring during work

tasks No dust monitoring will be conducted Work practices and investigation derived

waste (IDW) management practices will be used that will minimize the potential for

contaminated soil to be suspended in breathing space air Because vapor monitoring

action levels are lower than LEL action levels (10 percent of the LEL) no LEL

monitoring is required aside from that associated with confined space entry of the

recovery well vaults

POTENTIAL HEALTH HAZARD AND EXPOSURE RISK SCREENING

FOR WR GRACE amp Co - CONN M wp_Docswo992oooFiNALpiiASE i wo225 i6oo wro ATTA1-1 HSI GeoTrans inc

POTENTIAL HEALTH HAZARD AND EXPOSURE RISK SCREENING

The historical chemical data for the Site has been compiled through a thorough

review of past activities at the Site and a review of the Site electronic database For the

purposes of this HSP only data collected after the completion of the source removal

activities will be used to evaluate health and safety concerns at the Site The electronic

database was queried in March of 1999 to determine the maximum concentration and

frequency of compounds detected in groundwater at the Site since January 1 1996 (see

Table 1-1)

A hazard screening evaluation was performed for each compound identified in the

database search described above Table A-l indicates the associated health hazards

(exposure routes symptoms and target organs) for compounds detected at the Site and

the physical description (eg color solidliquidgas phase odor) Compounds for which

the NIOSH guide (NIOSH 1998) did not contain health hazard or physical description

information are shown with no information in the table row Some physical descriptions

for compounds were gathered from other sources (See Table A-l citation notes)

Table A-2 provides the exposure limits a summary of daily time weighted

average (Per Day TWA) and the 15 minute short term (15 min STEL) ceiling and

immediately dangerous to life or health (IDLH) exposure limits The limits shown are the

most stringent quantified exposure limits put forth by OSHA NIOSH and ACGIH for

each exposure limit category

Compounds that NIOSH considers to be potential occupational carcinogens are

designated with a check in the CA box in Tables A-2 A-3 and A-4 NIOSH usually

recommends that occupational exposures to carcinogens be limited to the lowest feasible

concentration (LFC) Those compounds NIOSH has identified as potential carcinogens

but has not quantified recommended exposure limits (REL) are designated with LFC

under the Most Stringent Exposure Limit column in Attachment A Table A-3 The

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINA1 PHASE I RT02251600 WPD ATT A1 -2 HSI GeOTiaHS lllC

ACGIH has categorized compounds into five carcinogenicity groups based on available

information Al for confirmed human carcinogens A2 for suspected human carcinogens

A3 for confirmed animal carcinogen with unknown relevance to humans A4 for not

classifiable as a human carcinogen and A5 for compounds not suspected as a human

carcinogen The carcinogenicity category for compounds which ACGIH has designated

is also shown in Tables A-2 A-3 and A-4

The compounds that have potential air monitoring concerns for this Site are those

compounds designated in Table A-3 with LFC an ACGIH carcinogenicity of Al or A2

a gas and vapor exposure limit of 5 ppm or less or with a suspended-in-air particulate

exposure limit of 1 mgm3 or less Tables A-3 and A-4 summarize the most stringent gas

and vapor and particulate exposure limits for these compounds respectively

The compounds with gas and vapor exposure limits of 5 ppm or less which were

detected at low frequency and low concentration (three or fewer times and at a

concentration less than 10 ppb (^gL)) are not considered to be of monitoring concern

(Table A-3) The remaining compounds in Table A-3 have only been detected at

locations where the concentration of benzene VDC and vinyl chloride represent the

majority of the total concentration of chemicals with monitoring concerns Because the

exposure limits for benzene VDC and vinyl chloride are low and these compounds make

up the majority of contamination in groundwater at the Site monitoring for benzene

VDC and vinyl chloride is a conservative means to evaluate work task exposure risks

which establish action level PPE modifications In order to screen for the compounds in

Table A-3 detector tubes or other compound specific monitoring devices for the indicator

parameters (benzene VDC and vinyl chloride) will be used according to action levels

associated with the tasks to be performed

The compounds with a suspended-in-air particulate exposure limit of 1 mgm3 or

less which were detected at low frequency and low concentration (three or fewer times

and at a concentration less than 10 ppb (^gL)) are not considered to be of monitoring

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FlNALPHAbElRI02251600 WO ATTA1-3 HSI GCOTfanS 1HC

concern (Table A-4) Work practices and investigation derived waste (1DW)

management practices will be used that will minimize the potential for contaminated soil

to be suspended in breathing space air above the exposure levels for the remaining

compounds

Table A-5 is a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) Because vapor monitoring action

levels are lower than LEL action levels (10 percent of the LEL) no LEL monitoring is

required

PERSONAL INJURY RESPONSE PLAN

Accidents

Physical injuries can range from a sprained ankle to a compound fracture or from a

minor cut to massive bleeding Depending on the seriousness of the injury treatment

may be given at the site by the Site Safety Officer For more serious injuries additional

assistance by ambulance may be required at the site or the victim may have to be treated

at a medical facility The Safety Officer will assess the seriousness of the injury and will

consult by phone with a physician if necessary

Chemical Exposure

Personnel including unauthorized personnel that suffer chemical overexposure shall

be treated in the following manner

bull Skin Contact Remove contaminated clothing Wash immediately with water Use soap if available

bull Inhalation Remove from contaminated atmosphere Artificial respiration is necessary Transport to hospital

bull Ingestion Never induce vomiting on an unconscious person Also never induce vomiting when acids alkalis or petroleum products are suspected Contact the poison control center

bull Ionizing Radiation Normal background 001 to 005 mRhr If less than 1 mRhr continue investigation with caution If greater than 1 mRhr evacuate site

These personnel shall be observed by the Site Safety Officer to ascertain whether

there are any symptoms resulting from overexposure If there is any visible manifestation

of overexposure such as skin irritation Project Personnel should be examined by a

physician All episodes of obvious chemical contamination are to be reviewed by the Site

Safety Officer in order to determine whether changes are needed in work procedures

Cold Stress

Persons working outdoors in temperatures at or below freezing may be frostbitten

Exposure to extreme cold for a short time may cause severe injury to the surface of the

body or result in profound generalized cooling causing death Areas of the body that

have a high surface-area-to-volume ratio such as fingers toes and ears are the most

susceptible Two factors influence the development of a cold injury ambient temperature

and the velocity of the wind Wind chill is used to describe the chilling effect of moving

air in combination with low temperature For instance 10degF with a wind of 15 mph is

equivalent in chilling effect to still air at -18degF

As a general rule the greatest incremental increase in wind chill occurs when a wind

of 5 mph increases to 10 mph Additionally water conducts heat 240 times faster than

air Thus the body cools suddenly when chemical-protective equipment is removed if the

clothing underneath is soaked with perspiration Local injury resulting from cold is

included in the generic term frostbite There are several degrees of damage

Systemic hypothermia is caused by exposure to freezing or rapidly dropping

temperature Its symptoms are usually exhibited in five stages (1) shivering (2) apathy

listlessness sleepiness and (sometimes) rapid cooling of the body to less than 95 degF (3)

unconsciousness glassy stare slow pulse and slow respiratory rate (4) freezing of the

extremities and finally (5) death

Prevention of Cold Stress can be achieved by (1) Modification of work schedules as

required by site conditions and personnel monitoring (2) Provision of shelters to protect

workers during rest periods (3) Maintenance of body heat at normal levels by wearing

adequate layers of clothing (4) Training site personnel to recognize and treat cold stress

(5) Frequent warm up breaks (6) Acclimation

Heat Stress

Wearing personal protective equipment puts a field worker at considerable risk of

developing heat stress This can result in health effects ranging from transient heat

fatigue to serious illness or death Heat stress is an aggregate of all the heat factors both

internal and external that work on the body

FOR WR GRACE amp Co - CONN MWP_DOCSNON2000F[NALP11ASEIRI0225600WPO ATT B1-18 HSI GCOTfanS IHC

External factors that contribute to heat stress include ambient air temperature

radiant temperature air velocity and the relative humidity Internal factors include

metabolic heat body core temperature respiration rate and acclimation

Early symptoms of heat stress include mental confusion and the inability to

concentrate heat rash and heat cramps (muscle spasms andor pain in hands feet and

abdomen) Acute and chronic heat stress impacts a workers temperament causing

impulsive aggressive and violent acts to be committed by the victim Signs of heat

exhaustion include pale cool moist skin heavy sweating dizziness nausea and fainting

Heat stroke is the most serious form of heat stress Immediate action must be taken to

cool the body and prevent serious injury Competent medical help must be obtained

Signs include red hot dry skin lack of or reduced perspiration nausea dizziness and

confusion strong rapid pulse and coma The case-fatality of heat-stroke and heat

exhaustion is probably no lower than 10 percent Because heat stress is one of the most

common (and potentially serious) illnesses at field sites regular monitoring and other

preventative precautions are vital

To monitor for heat stress measure

(1) Heart rate mdash Count the radial pulse during a 30-second period as early as possible during rest periods If the heart exceeds 110 beats per minute at the beginning of the rest period shorten the next work cycle by one-third and keep the rest period the same If the heart rate still exceeds 110 beats per minute at the next rest period shorten the following work cycle by one-third again

(2) Oral temperatures mdash Use an oral thermometer to measure the oral temperature at the end of the work period (before drinking) If oral temperature exceeds 996 degrees F shorten the next work cycle by one-third without changing the rest period Repeat if necessary Do not permit a worker to wear PPE when the workers oral temperature is above 1006 degrees F

(3) Body weight mdash If possible measure weight at the beginning and end of each day to see if enough fluids are being taken during the day The body water loss should not exceed 15 percent of total body weight in a work day

FOR WR GRACE amp Co - CONN M wp_DocsN099v2oooFiNALpHASFinjo22si6oowpD A I I B1-19 HSI GeoTrans inc

Prevention of heat stress can be achieved by

(1) Modification of work schedules as required by site conditions and personnel monitoring

(2) Provision of shelters or shaded areas to protect workers during rest periods

(3) Maintenance of body fluids at normal levels by drinking cold water and

(4) Training Site Personnel to recognize and treat heat stress signs

(5) Acclimation

The following safe work practices (SWP) apply to entry into confined spaces classified as non-permitshy

required The confined space must conform to the definition of a non-permit-required confined space as

discussed in the Confined Space Entry Program (see Document Control No 2-5 in Volume I) Entry into

spaces classified as non-permit-required are preferable over entry into permit-required spaces When

feasible efforts shall be directed to prepare confined spaces so they meet the definitions of non-permitshy

required confined space

If any of the procedures discussed in this SWP cannot be completed or an unanticipated hazard is

identified the non-permit-required status of the space will be revoked until the space is re-evaluated and

reapproved as a non-permit-required space by a technically qualified individual such as a Tetra Tech

health and safety specialist

Non-permit-required confined space entry procedures before entry into the space are listed below

bull The project manager and the site safety coordinator (SSC) should be notified of the need to enter into a confined space This notification must allow sufficient time to assemble necessary safety equipment

bull A blank Preparation and Testing of Non-Permit Required Confined Space form (Form CS-2) must be obtained (see Volume HI)

bull The necessary safety equipment can include but is not limited to atmospheric testing meters and devices a mechanical ventilator and a ladder for entry and exit

bull All equipment to be used during entry must be tested and inspected before use Atmospheric testing equipment shall be calibrated in accordance with the manufacturers instructions to ensure proper operation Calibration parameters shall be documented in the field logbook and the equipment will be tagged with a label specifying these parameters

bull Hazardous conditions associated with the removal of the entrance cover should be eliminated before opening the confined space After removal of the entrance cover the opening should be promptly barricaded by a railing temporary cover or other temporary barrier to prevent employees and equipment from accidentally falling through the opening

bull The internal atmosphere should be tested for the following conditions in the order given

Disclaimer This safe work practice (SWP) is the property of Tetra Tech Inc (Tetra Tech) and its subsidiaries Any reuse of the SWP without Terra Techs permission is at the sole nsk of the user The user will hold harmless Tetra Tech for any damages that result from unauthorized reuse of this SWP Authorized users are responsible for obtaining proper training and qualification from their employer before performing operations described in this SWP

Tetra Tech Inc Safe Work Practices Issue Date July 1998 Non-Permit-Required Confined Space Entry Practices Revision No 1 SWPNo 6-24 Page 2

- Oxygen content (should be between 195 to 235 percent)

- Combustible gases (should be less than 10 percent of the lower explosive limit)

- Potential toxic air contaminants

bull The space should be tested at all levels (top middle and bottom) and in all areas where work may occur The atmosphere within the space must not be hazardous whenever an employee is inside the space

bull If forced-air ventilation is used the following conditions apply

mdash Ventilation should not be used to control continuous sources of hazardous contaminants

- There must be a clean source of air that will not increase the hazard within the space

bull The entrant shall document on Form CS-2 that the space is safe for entry and that preshyentry measures required by this SWP have been taken The form shall be made available to each employee entering the space and shall be kept at the work site until completion of confined space work The certificate will then become part of the permanent project file

The atmosphere within the confined space must be tested periodically while entrants are within the

confined space Frequency of testing shall be every 30 minutes during the first 2 hours then hourly

afterwards when entrants are in the confined space If at any time during occupancy a hazardous

atmosphere is detected the entrants shall leave the space immediately The space shall then be evaluated

to determine how the hazardous atmosphere developed and measures shall be implemented to protect

employees from the hazardous atmosphere before any subsequent entry Re-entry shall not be allowed

until atmospheric testing demonstrates acceptable conditions

When changes in the use or configuration of a non-permit-required space cannot be eliminated or

controlled the SSC shall re-evaluate the space and if necessary reclassify it as a permit-required

confined space

Disclaimer This safe work practice (SWP) is the property of Tetra Tech Inc (Tetra Tech) and its subsidiaries Any reuse of the SWP without Tetra Techs permission is al the sole risk of the user The user will hold harmless Tetra Tech for any damages chat result from unauthorized reuse of this SWP Authorized users are responsible for obtaining proper training and qualification from their employer before performing operations described in this SWP

Eye Contact Immediately flush eyes with plenty of water for at least 15 minutes lifting lower and upper eyelids occasionally Get medical attention immediately

5 Fire Fighting Measures

Fire Extreme heat or contact with metals can release flammable hydrogen gas Explosion Not considered to be an explosion hazard Fire Extinguishing Media If involved in a fire use water spray Neutralize with soda ash or slaked lime Special Information In the event of a fire wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode Structural firefighters protective clothing is ineffective for fires involving hydrochloric acid Stay away from ends of tanks Cool tanks with water spray until well after fire is out

6 Accidental Release Measures

Ventilate area of leak or spill Wear appropriate personal protective equipment as specified in Section 8 Isolate hazard area Keep unnecessary and unprotected personnel from entering Contain and recover liquid when possible Neutralize with alkaline material (soda ash lime) then absorb with an inert material (e g vermiculite dry sand earth) and place in a chemical waste container Do not use combustible materials such as saw dust Do not flush to sewer US Regulations (CERCLA) require reporting spills and releases to soil water and air in excess of reportable quantities The toll free number for the US Coast Guard National Response Center is (800) 424-8802

J T Baker NEUTRASORB(tm) or TEAM(tm) Low Na+ acid neutralizers are recommended for spills of this product

7 Handling and Storage

Store in a cool dry ventilated storage area with acid resistant floors and good drainage Protect from physical damage Keep out of direct sunlight and away from heat water and incompatible materials Do not wash out container and use it for other purposes When diluting the acid should always be added slowly to water and in small amounts Never use hot water and never add water to the acid Water added to acid can cause uncontrolled boiling and splashing When opening metal containers use non-sparking tools because of the possibility of

mdash- hydrogen gas being present Containers of this material may be hazardous when empty since they retain product residues (vapors liquid) observe all warnings and precautions listed for the product

8 Exposure ControlsPersonal Protection

Airborne Exposure Limits -OSHA Permissible Exposure Limit (PEL) 5 ppm Ceiling -ACGIH Threshold Limit Value (TLV) 5 ppm Ceiling

Ventilation System A system of local andor general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source preventing dispersion of it into the general work area Please refer to the ACGIH document Industrial Ventilation A Manual of Recommended Practices most recent edition for details Personal Respirators (NIOSH Approved) If the exposure limit is exceeded a full facepiece respirator with an acid gas cartridge may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier whichever is lowest For emergencies or instances where the exposure levels are not known use a full-facepiece positive-pressure air-supplied respirator WARNING Air purifying respirators do not protect workers in oxygen-deficient atmospheres Skin Protection Rubber or neoprene gloves and additional protection including impervious boots apron or coveralls as needed in areas of unusual exposure to prevent skin contact Eye Protection Use chemical safety goggles andor a full face shield where splashing is possible Maintain eye wash fountain and quick-drench facilities in work area

Menzie-Cura amp Associates Addendum to the HIS Geotrans Health and Safety Plan WR Grace Superfund Site

Acton Massachusetts

Menzie-Cura amp Associates Inc adopts the HSI Geotrans Health and Safety Plan (HSP) The HSP contains a hazard assessment for contaminants found at the Site historically In addition to HSI Geotrans HSP Menzie-Cura amp Associates Inc personnel will following the boating safety procedures identified here when sampling in Sinking Pond and the reference pond

This work will take place in a small boat (possibly using a gasoline run outboard motor) All personnel will wear a United States Coast Guard approved personal flotation device (PFD) whenever working from the boat No smoking is allowed at any time in the boat or within 50 feet of it during refueling The Captain will be named at a later date At the Captains discretion he or she can modify or cancel any on-board operation for safety reasons Such reasons may include but are not limited to weather condition of boat or motor condition of sampling equipment or preparedness of personnel All personnel working on board will follow his or her orders

We will follow small boat safety procedures The boats transom or seats will contain a plate which describes the total weight capacity and other limitations of the particular boat used We will not exceed these The boats equipment will include motor full spare gasoline tank oars installed oar locks Danforth anchor 50 feet of half inch nylon anchor line terminated in three feet of half inch galvanized chain a metered and weighted line to estimate depth personal flotation devices (PFDs) for everyone on board a two quart canteen of drinking water (otherwise there should be no food on-board) and a cell phone

Personnel on board will each carry a belted and sheathed jack knife or rigging knife On-board personnel will be aware of the position of their bodies relative to coiled or faired lines or lines under tension Especially do not put hands or feet in any basket containing a faired line or sit upon a coiled deck line Always position yourself to one side of a line under tension Never position yourself behind a line under tension or between such a line and the gunnel of the boat or any other immovable object During over the side operations lower all lines Never let a weighted line free fall The most common way to drown is to go over the side with a free falling anchor or equipment line tangled around a leg arm or neck Grab samplers are not intended to free fall they are designed to be lowered It may be necessary to let certain samplers free fall a short distance (ie several feet) from above the bottom Lower them to that height above bottom Always know the depth to bottom before deploying equipment

Generally stay seated in the boat It is sometimes necessary to stand when deploying equipment Do this keeping your center of gravity as low as possible and as near the center line of the boat as possible Before standing or changing your position in the boat announce your intentions to all on-board

1123 SITE EMERGENCY PROCEDURES

FireExplosion

A fire that cannot be readily extinguished with one ten pound fire extinguisher

will be considered major and may require evacuation of Site personnel to safe areas The

SSO will call the fire department and will coordinate with fire emergency personnel as to

the selection of protective clothing and equipment as well as the use of proper fire

FOR wR GRACE amp Co - CONN M Wgt DOCSN0992000FINA1 PHASE I RIX02251600 wpo APR D1-6 HSI GeoTrans inc

fighting techniques The air downwind from any fireexplosion is to be monitored

immediately in order to protect workers and the nearby community If so required by the

air monitoring results the Vapor Emission Response Plan will be placed into effect If

personal injuries result from any fire or explosion the procedures outlined in the Personal

Injury Response Plan will be followed

Hazardous Spill

Any release or threat of release occurring during the work that constitutes an

emergency or may present an immediate threat to public health welfare or the

environment will be reported by the SSO or clients representative to the government

parties In the event of a spill the two main goals are to contain the spill as much as

possible and to minimize vapor emissions In order to accomplish these goals the

following equipment should be available at the Site

(1) an empty container

(2) polyethylene sheets

(3) absorbent materials and

(4) a shovel

Vapor Emission Response Plan

If any of the following conditions are identified at the Site exclusion zone

boundary all activities must be halted

(1) organic levels observed on air monitoring equipment of unknown

constituents are greater than 5 ppm above known background or

action levels requiring evacuation are reached or

(2) LEL levels greater than 10

If following the cessation of activities or as the result of an emergency

such as that described in the section on FireExplosion any of the above levels

persist downwind from the Site at the boundary of the exclusion zone then this

FOR W R GRACE amp Co - CONN MWP_DOCSW0992000F1NALPHASEIRI022SI600WPD APP D1-7 HSI GfiOTfanS lllC

Emergency Plan will automatically be placed into effect Upon activation of the

Emergency Plan the nearest perimeter of the closest downwind residential or

commercial property will immediately be monitored If organic levels from an

unknown source approach 5 ppm the local police authorities or property owner

will immediately be contacted by the SSO or clients representative and advised of

the situation

Personal Injury Response Plan

Accidents - Depending on the seriousness of the injury treatment may be

given at the Site by the SSO For more serious injuries additional assistance by

ambulance may be required at the Site or the victim may have to be treated at a

medical facility The SSO will assess the seriousness of the injury and will

consult by phone with a physician if necessary The SSO will file a complete

incident report with the Office Health and Safety Officer and the Project

Coordinator as soon as possible

Chemical Overexposure - Personnel including unauthorized personnel

that suffer chemical overexposure shall be treated in the following manner

bull Skin Contact Remove contaminated clothing Wash immediately with water Use soap if available

bull Inhalation Remove from contaminated atmosphere Artificial respiration if necessary Transport to hospital

bull Ingestion Never induce vomiting on an unconscious person Also never induce vomiting when acids alkalis or petroleum products are suspected Contact the poison control center

These personnel shall be observed by the SSO to ascertain whether there

are any symptoms resulting from overexposure If there is any visible

manifestation of overexposure such as skin irritation Project Personnel should be

FOR WR GRACE amp Co - CONN MWP DOCSN0992000F1NAL PHASE I RI02251600 WPD APP D1-8 HSI GeOTfanS IRC

examined by a physician All episodes of obvious chemical contamination are to

be reviewed by the SSO in order to determine whether changes are needed in

work procedures The SSO will file a complete incident report with the Office

Health and Safety Representative and the Project Coordinator as soon as possible

Radiation

Background for ionizing radiation is normally 001 to 005 mRhr

Background levels at the site that exceed these values should be listed under

background information If levels exceed background but are less than 1 mRhr

the investigation may continue with caution If levels exceed 1 mRhr all

activities must stop and personnel must evacuate the Site or portions of the Site

that exceed 1 mRhr

113 BACKGROUND INFORMATION

Overall Risk is High Moderate _

Low Unknown

1131 FACILITY DESCRIPTION

The Site is located in Acton and Concord Massachusetts on Independence Road

The Grace property is bordered by residential property on the northwest east and west

and industrial properties to the south and northeast Fort Pond Brook bounds the Grace

property to the northwest and the Assabet River bounds the Grace property to the

southeast The Assabet well field which supplies water for the Town of Acton is located

southwest of the Grace property Two inactive sand and gravel pits Massachusetts

Broken Stone Pit and Assabet Sand and Gravel are located south of the Grace property

Former occupants of the Site include American Cyanamid Company which

manufactured explosives and Dewey amp Almy Chemical Company Dewey amp Almy

acquired the property in 1946 and manufactured synthetic rubber container sealant

products An organic chemical plant which produced latex products plasticizers and

resins commenced operation in 1949 A paper battery separator production facility was

constructed in 1951

Grace acquired Dewey and Almy in 1954 and chemical operations were

continued at the Site Grace produced materials used to make concrete and organic

chemicals container sealing compounds latex products and paper and plastic battery

separators Wastewater and solid industrial wastes from these operations were disposed

in several on-site lagoons and an on-site landfill In addition the by-products of some

chemical processes were disposed of in the Slowdown Pit located in the central portion of

the property (Figure 1-2) Discharge to these areas ceased in 1980 Production of organic

chemicals was discontinued in 1982 A small distribution center for concrete additives

(Grace Construction Products) was moved to another location in September 1996 A

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINAL PHASE I RI022S1600 WPD APPD1-11 HSI GeOTianS lllC

second battery separator plant (Daramic) was constructed in 1979 and operations there

continued until 1991 The Daramic facility has not been considered part of the Site All

buildings with the exception of the building associated with the ARS have been

demolished

In 1978 groundwater contamination consisting mainly of 11-dichloroethene

(VDC) and lesser amounts of vinyl chloride ethylbenzene and benzene was detected in

two Acton municipal supply wells Assabet 1 and Assabet 2 located southwest of the

Grace property This discovery prompted a series of investigations which culminated in

the installation of the ARS beginning in late 1983 The ARS is a network of eleven

extraction wells designed to contain and cleanup contaminated groundwater and it is

currently operational

Following installation of the ARS extensive investigations were done by Grace

on in beneath and immediately surrounding the source areas to determine the nature and

extent of contamination by waste disposal practices Following a complete engineering

analysis of cleanup and remedial alternatives for the sources referred to as Operable

Unit-1 (OU-1) a remedy was selected for OU-1 Implementation of the remedy began in

November 1994 and was completed in July 1997 Following completion of the OU-1

remedy a comprehensive review of the groundwater quality and groundwater flow

conditions observed at the Site since the early 1980s and an evaluation of the

effectiveness of the ARS to contain and remediate groundwater affected by the Site was

done in the Initial Site Characterization Report (ISCR) (HSI GeoTrans 1998) While

data reviewed in the ISCR indicated that most areas of the Site containing groundwater

contamination are within the ARS capture zone and that contaminant concentrations in

most wells located outside of the capture zone have decreased significantly since 1984

uncertainties remain regarding the flow of groundwater and the distribution of

contaminants in certain areas of the Site The RIFS is designed to evaluate the extent of

FOR WR GRACE amp Co - CONN M wp_DocsN0992ooofiNALpnASEiRno225i6oowpo APPD1-12 HSI GeoTrans inc

groundwater contamination on- and off-Site and to determine whether additional remedial

measures are necessary to ensure accelerated restoration of the groundwater affected by

the Site to a fully usable condition

The Site property is now inactive as a manufacturing center The perimeter is

identified but due to the size is not secured Access to the Site is controlled through

locked gated entrances and exits The surrounding area is heavily wooded and restricts

the entrance of vehicles to the Site

1132 EXISTING CHEMICAL DATA

The existing historical chemical data for the Site has been compiled through a

thorough review of past activities at the Site and a review of the Site electronic database

For the purposes of this HSP only data collected after the completion of the source

removal activities will be used to evaluate health and safety concerns at the Site The

electronic database was queried in March of 1999 to determine the maximum

concentration and frequency of compounds detected in groundwater at the Site since

January 1 1996 (Table 1-1)

The volatile organic compounds (VOCs) with the highest frequency of detections

and maximum detection shown in parentheses at the Site are benzene (8600 ugL)

VDC (1000 ugL) and vinyl chloride (280 ugL) The semi-volatile organic compounds

(SVOCs) with the highest frequency of detections and maximum detection shown in

parenthesis at the Site are diethlyphthalate (110 ugL) bis(2-ethylhexyl)phthalate (120

ugL) and bis(2- chloroethyl)ether (41 ugL) The inorganic compounds with the highest

frequency of detections and maximum detection shown in parenthesis at the Site are

arsenic (13000 ugL) aluminum (42000 yUgL) nickel (890 ugL) and cadmium (16

ugL) The groundwater data collected indicate that pesticides and PCBs are not a

concern at the Site (HSI GeoTrans 1998) Therefore no pesticides or PCBs will be

monitored for during work tasks at the Site

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINM PHASE I RI0225I600 wro APPD1-13 HSI GeOTfanS lllC

Other compounds have been detected at varying concentrations and at a wide

range of frequencies at the Site Because such a wide range of VOCs SVOCs and

inorganics have been detected at the Site it was necessary to screen these compounds for

potential health hazards and exposure risks A full discussion of the potential health

hazard and exposure risk screening is provided in Attachment A Attachment A also

includes tables which indicate the physical description and associated health hazards for

each compound detected at the Site (Attachment A Table A-l) the exposure limits and

monitoring properties for each compound detected at the Site (Attachment A Table A-2)

compounds with gas and vapor exposure limits less than 5 ppm (Attachment A Table Ashy

3) compounds with particulate exposure limits less than 1 mgm3 (Attachment A Table

A-4) and a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) (Attachment A Table A-5)

Based on the screening discussed in Attachment A it was determined that the

compounds listed in Table 1-2 are contaminants of monitoring concern These

compounds have vapor exposure limits less than 5 ppm have been detected at least four

times and have a maximum detection concentration greater than 10 ppb (ugL) The

compounds found at the highest frequency and with greatest maximum concentration at

the Site benzene VDC and vinyl chloride are included in the list of compounds of

monitoring concern and comprise the lowest exposure limits Therefore benzene VDC

and vinyl chloride will be used as indicator compounds for vapor monitoring during work

tasks No dust monitoring will be conducted Work practices and investigation derived

waste (IDW) management practices will be used that will minimize the potential for

contaminated soil to be suspended in breathing space air Because vapor monitoring

action levels are lower than LEL action levels (10 percent of the LEL) no LEL

monitoring is required aside from that associated with confined space entry of the

recovery well vaults

POTENTIAL HEALTH HAZARD AND EXPOSURE RISK SCREENING

The historical chemical data for the Site has been compiled through a thorough

review of past activities at the Site and a review of the Site electronic database For the

purposes of this HSP only data collected after the completion of the source removal

activities will be used to evaluate health and safety concerns at the Site The electronic

database was queried in March of 1999 to determine the maximum concentration and

frequency of compounds detected in groundwater at the Site since January 1 1996 (see

Table 1-1)

A hazard screening evaluation was performed for each compound identified in the

database search described above Table A-l indicates the associated health hazards

(exposure routes symptoms and target organs) for compounds detected at the Site and

the physical description (eg color solidliquidgas phase odor) Compounds for which

the NIOSH guide (NIOSH 1998) did not contain health hazard or physical description

information are shown with no information in the table row Some physical descriptions

for compounds were gathered from other sources (See Table A-l citation notes)

Table A-2 provides the exposure limits a summary of daily time weighted

average (Per Day TWA) and the 15 minute short term (15 min STEL) ceiling and

immediately dangerous to life or health (IDLH) exposure limits The limits shown are the

most stringent quantified exposure limits put forth by OSHA NIOSH and ACGIH for

each exposure limit category

Compounds that NIOSH considers to be potential occupational carcinogens are

designated with a check in the CA box in Tables A-2 A-3 and A-4 NIOSH usually

recommends that occupational exposures to carcinogens be limited to the lowest feasible

concentration (LFC) Those compounds NIOSH has identified as potential carcinogens

but has not quantified recommended exposure limits (REL) are designated with LFC

under the Most Stringent Exposure Limit column in Attachment A Table A-3 The

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINA1 PHASE I RT02251600 WPD ATT A1 -2 HSI GeOTiaHS lllC

ACGIH has categorized compounds into five carcinogenicity groups based on available

information Al for confirmed human carcinogens A2 for suspected human carcinogens

A3 for confirmed animal carcinogen with unknown relevance to humans A4 for not

classifiable as a human carcinogen and A5 for compounds not suspected as a human

carcinogen The carcinogenicity category for compounds which ACGIH has designated

is also shown in Tables A-2 A-3 and A-4

The compounds that have potential air monitoring concerns for this Site are those

compounds designated in Table A-3 with LFC an ACGIH carcinogenicity of Al or A2

a gas and vapor exposure limit of 5 ppm or less or with a suspended-in-air particulate

exposure limit of 1 mgm3 or less Tables A-3 and A-4 summarize the most stringent gas

and vapor and particulate exposure limits for these compounds respectively

The compounds with gas and vapor exposure limits of 5 ppm or less which were

detected at low frequency and low concentration (three or fewer times and at a

concentration less than 10 ppb (^gL)) are not considered to be of monitoring concern

(Table A-3) The remaining compounds in Table A-3 have only been detected at

locations where the concentration of benzene VDC and vinyl chloride represent the

majority of the total concentration of chemicals with monitoring concerns Because the

exposure limits for benzene VDC and vinyl chloride are low and these compounds make

up the majority of contamination in groundwater at the Site monitoring for benzene

VDC and vinyl chloride is a conservative means to evaluate work task exposure risks

which establish action level PPE modifications In order to screen for the compounds in

Table A-3 detector tubes or other compound specific monitoring devices for the indicator

parameters (benzene VDC and vinyl chloride) will be used according to action levels

associated with the tasks to be performed

The compounds with a suspended-in-air particulate exposure limit of 1 mgm3 or

less which were detected at low frequency and low concentration (three or fewer times

and at a concentration less than 10 ppb (^gL)) are not considered to be of monitoring

concern (Table A-4) Work practices and investigation derived waste (1DW)

management practices will be used that will minimize the potential for contaminated soil

to be suspended in breathing space air above the exposure levels for the remaining

compounds

Table A-5 is a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) Because vapor monitoring action

levels are lower than LEL action levels (10 percent of the LEL) no LEL monitoring is

required

PERSONAL INJURY RESPONSE PLAN

Accidents

Physical injuries can range from a sprained ankle to a compound fracture or from a

minor cut to massive bleeding Depending on the seriousness of the injury treatment

may be given at the site by the Site Safety Officer For more serious injuries additional

assistance by ambulance may be required at the site or the victim may have to be treated

at a medical facility The Safety Officer will assess the seriousness of the injury and will

consult by phone with a physician if necessary

Chemical Exposure

Personnel including unauthorized personnel that suffer chemical overexposure shall

be treated in the following manner

bull Skin Contact Remove contaminated clothing Wash immediately with water Use soap if available

bull Inhalation Remove from contaminated atmosphere Artificial respiration is necessary Transport to hospital

bull Ingestion Never induce vomiting on an unconscious person Also never induce vomiting when acids alkalis or petroleum products are suspected Contact the poison control center

bull Ionizing Radiation Normal background 001 to 005 mRhr If less than 1 mRhr continue investigation with caution If greater than 1 mRhr evacuate site

These personnel shall be observed by the Site Safety Officer to ascertain whether

there are any symptoms resulting from overexposure If there is any visible manifestation

of overexposure such as skin irritation Project Personnel should be examined by a

physician All episodes of obvious chemical contamination are to be reviewed by the Site

Safety Officer in order to determine whether changes are needed in work procedures

Cold Stress

Persons working outdoors in temperatures at or below freezing may be frostbitten

Exposure to extreme cold for a short time may cause severe injury to the surface of the

body or result in profound generalized cooling causing death Areas of the body that

have a high surface-area-to-volume ratio such as fingers toes and ears are the most

susceptible Two factors influence the development of a cold injury ambient temperature

and the velocity of the wind Wind chill is used to describe the chilling effect of moving

air in combination with low temperature For instance 10degF with a wind of 15 mph is

equivalent in chilling effect to still air at -18degF

As a general rule the greatest incremental increase in wind chill occurs when a wind

of 5 mph increases to 10 mph Additionally water conducts heat 240 times faster than

air Thus the body cools suddenly when chemical-protective equipment is removed if the

clothing underneath is soaked with perspiration Local injury resulting from cold is

included in the generic term frostbite There are several degrees of damage

Systemic hypothermia is caused by exposure to freezing or rapidly dropping

temperature Its symptoms are usually exhibited in five stages (1) shivering (2) apathy

listlessness sleepiness and (sometimes) rapid cooling of the body to less than 95 degF (3)

unconsciousness glassy stare slow pulse and slow respiratory rate (4) freezing of the

extremities and finally (5) death

Prevention of Cold Stress can be achieved by (1) Modification of work schedules as

required by site conditions and personnel monitoring (2) Provision of shelters to protect

workers during rest periods (3) Maintenance of body heat at normal levels by wearing

adequate layers of clothing (4) Training site personnel to recognize and treat cold stress

(5) Frequent warm up breaks (6) Acclimation

Heat Stress

Wearing personal protective equipment puts a field worker at considerable risk of

developing heat stress This can result in health effects ranging from transient heat

fatigue to serious illness or death Heat stress is an aggregate of all the heat factors both

internal and external that work on the body

FOR WR GRACE amp Co - CONN MWP_DOCSNON2000F[NALP11ASEIRI0225600WPO ATT B1-18 HSI GCOTfanS IHC

External factors that contribute to heat stress include ambient air temperature

radiant temperature air velocity and the relative humidity Internal factors include

metabolic heat body core temperature respiration rate and acclimation

Early symptoms of heat stress include mental confusion and the inability to

concentrate heat rash and heat cramps (muscle spasms andor pain in hands feet and

abdomen) Acute and chronic heat stress impacts a workers temperament causing

impulsive aggressive and violent acts to be committed by the victim Signs of heat

exhaustion include pale cool moist skin heavy sweating dizziness nausea and fainting

Heat stroke is the most serious form of heat stress Immediate action must be taken to

cool the body and prevent serious injury Competent medical help must be obtained

Signs include red hot dry skin lack of or reduced perspiration nausea dizziness and

confusion strong rapid pulse and coma The case-fatality of heat-stroke and heat

exhaustion is probably no lower than 10 percent Because heat stress is one of the most

common (and potentially serious) illnesses at field sites regular monitoring and other

preventative precautions are vital

To monitor for heat stress measure

(1) Heart rate mdash Count the radial pulse during a 30-second period as early as possible during rest periods If the heart exceeds 110 beats per minute at the beginning of the rest period shorten the next work cycle by one-third and keep the rest period the same If the heart rate still exceeds 110 beats per minute at the next rest period shorten the following work cycle by one-third again

(2) Oral temperatures mdash Use an oral thermometer to measure the oral temperature at the end of the work period (before drinking) If oral temperature exceeds 996 degrees F shorten the next work cycle by one-third without changing the rest period Repeat if necessary Do not permit a worker to wear PPE when the workers oral temperature is above 1006 degrees F

(3) Body weight mdash If possible measure weight at the beginning and end of each day to see if enough fluids are being taken during the day The body water loss should not exceed 15 percent of total body weight in a work day

FOR WR GRACE amp Co - CONN M wp_DocsN099v2oooFiNALpHASFinjo22si6oowpD A I I B1-19 HSI GeoTrans inc

Prevention of heat stress can be achieved by

(1) Modification of work schedules as required by site conditions and personnel monitoring

(2) Provision of shelters or shaded areas to protect workers during rest periods

(3) Maintenance of body fluids at normal levels by drinking cold water and

(4) Training Site Personnel to recognize and treat heat stress signs

(5) Acclimation

discussed in the Confined Space Entry Program (see Document Control No 2-5 in Volume I) Entry into

spaces classified as non-permit-required are preferable over entry into permit-required spaces When

feasible efforts shall be directed to prepare confined spaces so they meet the definitions of non-permitshy

required confined space

If any of the procedures discussed in this SWP cannot be completed or an unanticipated hazard is

identified the non-permit-required status of the space will be revoked until the space is re-evaluated and

reapproved as a non-permit-required space by a technically qualified individual such as a Tetra Tech

health and safety specialist

Non-permit-required confined space entry procedures before entry into the space are listed below

bull The project manager and the site safety coordinator (SSC) should be notified of the need to enter into a confined space This notification must allow sufficient time to assemble necessary safety equipment

bull A blank Preparation and Testing of Non-Permit Required Confined Space form (Form CS-2) must be obtained (see Volume HI)

bull The necessary safety equipment can include but is not limited to atmospheric testing meters and devices a mechanical ventilator and a ladder for entry and exit

bull All equipment to be used during entry must be tested and inspected before use Atmospheric testing equipment shall be calibrated in accordance with the manufacturers instructions to ensure proper operation Calibration parameters shall be documented in the field logbook and the equipment will be tagged with a label specifying these parameters

bull Hazardous conditions associated with the removal of the entrance cover should be eliminated before opening the confined space After removal of the entrance cover the opening should be promptly barricaded by a railing temporary cover or other temporary barrier to prevent employees and equipment from accidentally falling through the opening

bull The internal atmosphere should be tested for the following conditions in the order given

- Oxygen content (should be between 195 to 235 percent)

- Combustible gases (should be less than 10 percent of the lower explosive limit)

- Potential toxic air contaminants

bull The space should be tested at all levels (top middle and bottom) and in all areas where work may occur The atmosphere within the space must not be hazardous whenever an employee is inside the space

bull If forced-air ventilation is used the following conditions apply

mdash Ventilation should not be used to control continuous sources of hazardous contaminants

- There must be a clean source of air that will not increase the hazard within the space

bull The entrant shall document on Form CS-2 that the space is safe for entry and that preshyentry measures required by this SWP have been taken The form shall be made available to each employee entering the space and shall be kept at the work site until completion of confined space work The certificate will then become part of the permanent project file

The atmosphere within the confined space must be tested periodically while entrants are within the

confined space Frequency of testing shall be every 30 minutes during the first 2 hours then hourly

afterwards when entrants are in the confined space If at any time during occupancy a hazardous

atmosphere is detected the entrants shall leave the space immediately The space shall then be evaluated

to determine how the hazardous atmosphere developed and measures shall be implemented to protect

employees from the hazardous atmosphere before any subsequent entry Re-entry shall not be allowed

until atmospheric testing demonstrates acceptable conditions

When changes in the use or configuration of a non-permit-required space cannot be eliminated or

controlled the SSC shall re-evaluate the space and if necessary reclassify it as a permit-required

confined space

Eye Contact Immediately flush eyes with plenty of water for at least 15 minutes lifting lower and upper eyelids occasionally Get medical attention immediately

5 Fire Fighting Measures

Fire Extreme heat or contact with metals can release flammable hydrogen gas Explosion Not considered to be an explosion hazard Fire Extinguishing Media If involved in a fire use water spray Neutralize with soda ash or slaked lime Special Information In the event of a fire wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode Structural firefighters protective clothing is ineffective for fires involving hydrochloric acid Stay away from ends of tanks Cool tanks with water spray until well after fire is out

6 Accidental Release Measures

Ventilate area of leak or spill Wear appropriate personal protective equipment as specified in Section 8 Isolate hazard area Keep unnecessary and unprotected personnel from entering Contain and recover liquid when possible Neutralize with alkaline material (soda ash lime) then absorb with an inert material (e g vermiculite dry sand earth) and place in a chemical waste container Do not use combustible materials such as saw dust Do not flush to sewer US Regulations (CERCLA) require reporting spills and releases to soil water and air in excess of reportable quantities The toll free number for the US Coast Guard National Response Center is (800) 424-8802

J T Baker NEUTRASORB(tm) or TEAM(tm) Low Na+ acid neutralizers are recommended for spills of this product

7 Handling and Storage

Store in a cool dry ventilated storage area with acid resistant floors and good drainage Protect from physical damage Keep out of direct sunlight and away from heat water and incompatible materials Do not wash out container and use it for other purposes When diluting the acid should always be added slowly to water and in small amounts Never use hot water and never add water to the acid Water added to acid can cause uncontrolled boiling and splashing When opening metal containers use non-sparking tools because of the possibility of

mdash- hydrogen gas being present Containers of this material may be hazardous when empty since they retain product residues (vapors liquid) observe all warnings and precautions listed for the product

8 Exposure ControlsPersonal Protection

Airborne Exposure Limits -OSHA Permissible Exposure Limit (PEL) 5 ppm Ceiling -ACGIH Threshold Limit Value (TLV) 5 ppm Ceiling

Ventilation System A system of local andor general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source preventing dispersion of it into the general work area Please refer to the ACGIH document Industrial Ventilation A Manual of Recommended Practices most recent edition for details Personal Respirators (NIOSH Approved) If the exposure limit is exceeded a full facepiece respirator with an acid gas cartridge may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier whichever is lowest For emergencies or instances where the exposure levels are not known use a full-facepiece positive-pressure air-supplied respirator WARNING Air purifying respirators do not protect workers in oxygen-deficient atmospheres Skin Protection Rubber or neoprene gloves and additional protection including impervious boots apron or coveralls as needed in areas of unusual exposure to prevent skin contact Eye Protection Use chemical safety goggles andor a full face shield where splashing is possible Maintain eye wash fountain and quick-drench facilities in work area

Menzie-Cura amp Associates Addendum to the HIS Geotrans Health and Safety Plan WR Grace Superfund Site

Acton Massachusetts

Menzie-Cura amp Associates Inc adopts the HSI Geotrans Health and Safety Plan (HSP) The HSP contains a hazard assessment for contaminants found at the Site historically In addition to HSI Geotrans HSP Menzie-Cura amp Associates Inc personnel will following the boating safety procedures identified here when sampling in Sinking Pond and the reference pond

This work will take place in a small boat (possibly using a gasoline run outboard motor) All personnel will wear a United States Coast Guard approved personal flotation device (PFD) whenever working from the boat No smoking is allowed at any time in the boat or within 50 feet of it during refueling The Captain will be named at a later date At the Captains discretion he or she can modify or cancel any on-board operation for safety reasons Such reasons may include but are not limited to weather condition of boat or motor condition of sampling equipment or preparedness of personnel All personnel working on board will follow his or her orders

We will follow small boat safety procedures The boats transom or seats will contain a plate which describes the total weight capacity and other limitations of the particular boat used We will not exceed these The boats equipment will include motor full spare gasoline tank oars installed oar locks Danforth anchor 50 feet of half inch nylon anchor line terminated in three feet of half inch galvanized chain a metered and weighted line to estimate depth personal flotation devices (PFDs) for everyone on board a two quart canteen of drinking water (otherwise there should be no food on-board) and a cell phone

Personnel on board will each carry a belted and sheathed jack knife or rigging knife On-board personnel will be aware of the position of their bodies relative to coiled or faired lines or lines under tension Especially do not put hands or feet in any basket containing a faired line or sit upon a coiled deck line Always position yourself to one side of a line under tension Never position yourself behind a line under tension or between such a line and the gunnel of the boat or any other immovable object During over the side operations lower all lines Never let a weighted line free fall The most common way to drown is to go over the side with a free falling anchor or equipment line tangled around a leg arm or neck Grab samplers are not intended to free fall they are designed to be lowered It may be necessary to let certain samplers free fall a short distance (ie several feet) from above the bottom Lower them to that height above bottom Always know the depth to bottom before deploying equipment

Generally stay seated in the boat It is sometimes necessary to stand when deploying equipment Do this keeping your center of gravity as low as possible and as near the center line of the boat as possible Before standing or changing your position in the boat announce your intentions to all on-board

1123 SITE EMERGENCY PROCEDURES

FireExplosion

A fire that cannot be readily extinguished with one ten pound fire extinguisher

will be considered major and may require evacuation of Site personnel to safe areas The

SSO will call the fire department and will coordinate with fire emergency personnel as to

the selection of protective clothing and equipment as well as the use of proper fire

FOR wR GRACE amp Co - CONN M Wgt DOCSN0992000FINA1 PHASE I RIX02251600 wpo APR D1-6 HSI GeoTrans inc

fighting techniques The air downwind from any fireexplosion is to be monitored

immediately in order to protect workers and the nearby community If so required by the

air monitoring results the Vapor Emission Response Plan will be placed into effect If

personal injuries result from any fire or explosion the procedures outlined in the Personal

Injury Response Plan will be followed

Hazardous Spill

Any release or threat of release occurring during the work that constitutes an

emergency or may present an immediate threat to public health welfare or the

environment will be reported by the SSO or clients representative to the government

parties In the event of a spill the two main goals are to contain the spill as much as

possible and to minimize vapor emissions In order to accomplish these goals the

following equipment should be available at the Site

(1) an empty container

(2) polyethylene sheets

(3) absorbent materials and

(4) a shovel

Vapor Emission Response Plan

If any of the following conditions are identified at the Site exclusion zone

boundary all activities must be halted

(1) organic levels observed on air monitoring equipment of unknown

constituents are greater than 5 ppm above known background or

action levels requiring evacuation are reached or

(2) LEL levels greater than 10

If following the cessation of activities or as the result of an emergency

such as that described in the section on FireExplosion any of the above levels

persist downwind from the Site at the boundary of the exclusion zone then this

FOR W R GRACE amp Co - CONN MWP_DOCSW0992000F1NALPHASEIRI022SI600WPD APP D1-7 HSI GfiOTfanS lllC

Emergency Plan will automatically be placed into effect Upon activation of the

Emergency Plan the nearest perimeter of the closest downwind residential or

commercial property will immediately be monitored If organic levels from an

unknown source approach 5 ppm the local police authorities or property owner

will immediately be contacted by the SSO or clients representative and advised of

the situation

Personal Injury Response Plan

Accidents - Depending on the seriousness of the injury treatment may be

given at the Site by the SSO For more serious injuries additional assistance by

ambulance may be required at the Site or the victim may have to be treated at a

medical facility The SSO will assess the seriousness of the injury and will

consult by phone with a physician if necessary The SSO will file a complete

incident report with the Office Health and Safety Officer and the Project

Coordinator as soon as possible

Chemical Overexposure - Personnel including unauthorized personnel

that suffer chemical overexposure shall be treated in the following manner

bull Skin Contact Remove contaminated clothing Wash immediately with water Use soap if available

bull Inhalation Remove from contaminated atmosphere Artificial respiration if necessary Transport to hospital

bull Ingestion Never induce vomiting on an unconscious person Also never induce vomiting when acids alkalis or petroleum products are suspected Contact the poison control center

These personnel shall be observed by the SSO to ascertain whether there

are any symptoms resulting from overexposure If there is any visible

manifestation of overexposure such as skin irritation Project Personnel should be

FOR WR GRACE amp Co - CONN MWP DOCSN0992000F1NAL PHASE I RI02251600 WPD APP D1-8 HSI GeOTfanS IRC

examined by a physician All episodes of obvious chemical contamination are to

be reviewed by the SSO in order to determine whether changes are needed in

work procedures The SSO will file a complete incident report with the Office

Health and Safety Representative and the Project Coordinator as soon as possible

Radiation

Background for ionizing radiation is normally 001 to 005 mRhr

Background levels at the site that exceed these values should be listed under

background information If levels exceed background but are less than 1 mRhr

the investigation may continue with caution If levels exceed 1 mRhr all

activities must stop and personnel must evacuate the Site or portions of the Site

that exceed 1 mRhr

113 BACKGROUND INFORMATION

Overall Risk is High Moderate _

Low Unknown

1131 FACILITY DESCRIPTION

The Site is located in Acton and Concord Massachusetts on Independence Road

The Grace property is bordered by residential property on the northwest east and west

and industrial properties to the south and northeast Fort Pond Brook bounds the Grace

property to the northwest and the Assabet River bounds the Grace property to the

southeast The Assabet well field which supplies water for the Town of Acton is located

southwest of the Grace property Two inactive sand and gravel pits Massachusetts

Broken Stone Pit and Assabet Sand and Gravel are located south of the Grace property

Former occupants of the Site include American Cyanamid Company which

manufactured explosives and Dewey amp Almy Chemical Company Dewey amp Almy

acquired the property in 1946 and manufactured synthetic rubber container sealant

products An organic chemical plant which produced latex products plasticizers and

resins commenced operation in 1949 A paper battery separator production facility was

constructed in 1951

Grace acquired Dewey and Almy in 1954 and chemical operations were

continued at the Site Grace produced materials used to make concrete and organic

chemicals container sealing compounds latex products and paper and plastic battery

separators Wastewater and solid industrial wastes from these operations were disposed

in several on-site lagoons and an on-site landfill In addition the by-products of some

chemical processes were disposed of in the Slowdown Pit located in the central portion of

the property (Figure 1-2) Discharge to these areas ceased in 1980 Production of organic

chemicals was discontinued in 1982 A small distribution center for concrete additives

(Grace Construction Products) was moved to another location in September 1996 A

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINAL PHASE I RI022S1600 WPD APPD1-11 HSI GeOTianS lllC

second battery separator plant (Daramic) was constructed in 1979 and operations there

continued until 1991 The Daramic facility has not been considered part of the Site All

buildings with the exception of the building associated with the ARS have been

demolished

In 1978 groundwater contamination consisting mainly of 11-dichloroethene

(VDC) and lesser amounts of vinyl chloride ethylbenzene and benzene was detected in

two Acton municipal supply wells Assabet 1 and Assabet 2 located southwest of the

Grace property This discovery prompted a series of investigations which culminated in

the installation of the ARS beginning in late 1983 The ARS is a network of eleven

extraction wells designed to contain and cleanup contaminated groundwater and it is

currently operational

Following installation of the ARS extensive investigations were done by Grace

on in beneath and immediately surrounding the source areas to determine the nature and

extent of contamination by waste disposal practices Following a complete engineering

analysis of cleanup and remedial alternatives for the sources referred to as Operable

Unit-1 (OU-1) a remedy was selected for OU-1 Implementation of the remedy began in

November 1994 and was completed in July 1997 Following completion of the OU-1

remedy a comprehensive review of the groundwater quality and groundwater flow

conditions observed at the Site since the early 1980s and an evaluation of the

effectiveness of the ARS to contain and remediate groundwater affected by the Site was

done in the Initial Site Characterization Report (ISCR) (HSI GeoTrans 1998) While

data reviewed in the ISCR indicated that most areas of the Site containing groundwater

contamination are within the ARS capture zone and that contaminant concentrations in

most wells located outside of the capture zone have decreased significantly since 1984

uncertainties remain regarding the flow of groundwater and the distribution of

contaminants in certain areas of the Site The RIFS is designed to evaluate the extent of

FOR WR GRACE amp Co - CONN M wp_DocsN0992ooofiNALpnASEiRno225i6oowpo APPD1-12 HSI GeoTrans inc

groundwater contamination on- and off-Site and to determine whether additional remedial

measures are necessary to ensure accelerated restoration of the groundwater affected by

the Site to a fully usable condition

The Site property is now inactive as a manufacturing center The perimeter is

identified but due to the size is not secured Access to the Site is controlled through

locked gated entrances and exits The surrounding area is heavily wooded and restricts

the entrance of vehicles to the Site

1132 EXISTING CHEMICAL DATA

The existing historical chemical data for the Site has been compiled through a

thorough review of past activities at the Site and a review of the Site electronic database

For the purposes of this HSP only data collected after the completion of the source

removal activities will be used to evaluate health and safety concerns at the Site The

electronic database was queried in March of 1999 to determine the maximum

concentration and frequency of compounds detected in groundwater at the Site since

January 1 1996 (Table 1-1)

The volatile organic compounds (VOCs) with the highest frequency of detections

and maximum detection shown in parentheses at the Site are benzene (8600 ugL)

VDC (1000 ugL) and vinyl chloride (280 ugL) The semi-volatile organic compounds

(SVOCs) with the highest frequency of detections and maximum detection shown in

parenthesis at the Site are diethlyphthalate (110 ugL) bis(2-ethylhexyl)phthalate (120

ugL) and bis(2- chloroethyl)ether (41 ugL) The inorganic compounds with the highest

frequency of detections and maximum detection shown in parenthesis at the Site are

arsenic (13000 ugL) aluminum (42000 yUgL) nickel (890 ugL) and cadmium (16

ugL) The groundwater data collected indicate that pesticides and PCBs are not a

concern at the Site (HSI GeoTrans 1998) Therefore no pesticides or PCBs will be

monitored for during work tasks at the Site

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINM PHASE I RI0225I600 wro APPD1-13 HSI GeOTfanS lllC

Other compounds have been detected at varying concentrations and at a wide

range of frequencies at the Site Because such a wide range of VOCs SVOCs and

inorganics have been detected at the Site it was necessary to screen these compounds for

potential health hazards and exposure risks A full discussion of the potential health

hazard and exposure risk screening is provided in Attachment A Attachment A also

includes tables which indicate the physical description and associated health hazards for

each compound detected at the Site (Attachment A Table A-l) the exposure limits and

monitoring properties for each compound detected at the Site (Attachment A Table A-2)

compounds with gas and vapor exposure limits less than 5 ppm (Attachment A Table Ashy

3) compounds with particulate exposure limits less than 1 mgm3 (Attachment A Table

A-4) and a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) (Attachment A Table A-5)

Based on the screening discussed in Attachment A it was determined that the

compounds listed in Table 1-2 are contaminants of monitoring concern These

compounds have vapor exposure limits less than 5 ppm have been detected at least four

times and have a maximum detection concentration greater than 10 ppb (ugL) The

compounds found at the highest frequency and with greatest maximum concentration at

the Site benzene VDC and vinyl chloride are included in the list of compounds of

monitoring concern and comprise the lowest exposure limits Therefore benzene VDC

and vinyl chloride will be used as indicator compounds for vapor monitoring during work

tasks No dust monitoring will be conducted Work practices and investigation derived

waste (IDW) management practices will be used that will minimize the potential for

contaminated soil to be suspended in breathing space air Because vapor monitoring

action levels are lower than LEL action levels (10 percent of the LEL) no LEL

monitoring is required aside from that associated with confined space entry of the

recovery well vaults

POTENTIAL HEALTH HAZARD AND EXPOSURE RISK SCREENING

POTENTIAL HEALTH HAZARD AND EXPOSURE RISK SCREENING

The historical chemical data for the Site has been compiled through a thorough

review of past activities at the Site and a review of the Site electronic database For the

purposes of this HSP only data collected after the completion of the source removal

activities will be used to evaluate health and safety concerns at the Site The electronic

database was queried in March of 1999 to determine the maximum concentration and

frequency of compounds detected in groundwater at the Site since January 1 1996 (see

Table 1-1)

A hazard screening evaluation was performed for each compound identified in the

database search described above Table A-l indicates the associated health hazards

(exposure routes symptoms and target organs) for compounds detected at the Site and

the physical description (eg color solidliquidgas phase odor) Compounds for which

the NIOSH guide (NIOSH 1998) did not contain health hazard or physical description

information are shown with no information in the table row Some physical descriptions

for compounds were gathered from other sources (See Table A-l citation notes)

Table A-2 provides the exposure limits a summary of daily time weighted

average (Per Day TWA) and the 15 minute short term (15 min STEL) ceiling and

immediately dangerous to life or health (IDLH) exposure limits The limits shown are the

most stringent quantified exposure limits put forth by OSHA NIOSH and ACGIH for

each exposure limit category

Compounds that NIOSH considers to be potential occupational carcinogens are

designated with a check in the CA box in Tables A-2 A-3 and A-4 NIOSH usually

recommends that occupational exposures to carcinogens be limited to the lowest feasible

concentration (LFC) Those compounds NIOSH has identified as potential carcinogens

but has not quantified recommended exposure limits (REL) are designated with LFC

under the Most Stringent Exposure Limit column in Attachment A Table A-3 The

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINA1 PHASE I RT02251600 WPD ATT A1 -2 HSI GeOTiaHS lllC

ACGIH has categorized compounds into five carcinogenicity groups based on available

information Al for confirmed human carcinogens A2 for suspected human carcinogens

A3 for confirmed animal carcinogen with unknown relevance to humans A4 for not

classifiable as a human carcinogen and A5 for compounds not suspected as a human

carcinogen The carcinogenicity category for compounds which ACGIH has designated

is also shown in Tables A-2 A-3 and A-4

The compounds that have potential air monitoring concerns for this Site are those

compounds designated in Table A-3 with LFC an ACGIH carcinogenicity of Al or A2

a gas and vapor exposure limit of 5 ppm or less or with a suspended-in-air particulate

exposure limit of 1 mgm3 or less Tables A-3 and A-4 summarize the most stringent gas

and vapor and particulate exposure limits for these compounds respectively

The compounds with gas and vapor exposure limits of 5 ppm or less which were

detected at low frequency and low concentration (three or fewer times and at a

concentration less than 10 ppb (^gL)) are not considered to be of monitoring concern

(Table A-3) The remaining compounds in Table A-3 have only been detected at

locations where the concentration of benzene VDC and vinyl chloride represent the

majority of the total concentration of chemicals with monitoring concerns Because the

exposure limits for benzene VDC and vinyl chloride are low and these compounds make

up the majority of contamination in groundwater at the Site monitoring for benzene

VDC and vinyl chloride is a conservative means to evaluate work task exposure risks

which establish action level PPE modifications In order to screen for the compounds in

Table A-3 detector tubes or other compound specific monitoring devices for the indicator

parameters (benzene VDC and vinyl chloride) will be used according to action levels

associated with the tasks to be performed

The compounds with a suspended-in-air particulate exposure limit of 1 mgm3 or

less which were detected at low frequency and low concentration (three or fewer times

and at a concentration less than 10 ppb (^gL)) are not considered to be of monitoring

concern (Table A-4) Work practices and investigation derived waste (1DW)

management practices will be used that will minimize the potential for contaminated soil

to be suspended in breathing space air above the exposure levels for the remaining

compounds

Table A-5 is a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) Because vapor monitoring action

levels are lower than LEL action levels (10 percent of the LEL) no LEL monitoring is

required

Cold Stress

Persons working outdoors in temperatures at or below freezing may be frostbitten

Exposure to extreme cold for a short time may cause severe injury to the surface of the

body or result in profound generalized cooling causing death Areas of the body that

have a high surface-area-to-volume ratio such as fingers toes and ears are the most

susceptible Two factors influence the development of a cold injury ambient temperature

and the velocity of the wind Wind chill is used to describe the chilling effect of moving

air in combination with low temperature For instance 10degF with a wind of 15 mph is

equivalent in chilling effect to still air at -18degF

As a general rule the greatest incremental increase in wind chill occurs when a wind

of 5 mph increases to 10 mph Additionally water conducts heat 240 times faster than

air Thus the body cools suddenly when chemical-protective equipment is removed if the

clothing underneath is soaked with perspiration Local injury resulting from cold is

included in the generic term frostbite There are several degrees of damage

Systemic hypothermia is caused by exposure to freezing or rapidly dropping

temperature Its symptoms are usually exhibited in five stages (1) shivering (2) apathy

listlessness sleepiness and (sometimes) rapid cooling of the body to less than 95 degF (3)

unconsciousness glassy stare slow pulse and slow respiratory rate (4) freezing of the

extremities and finally (5) death

Prevention of Cold Stress can be achieved by (1) Modification of work schedules as

required by site conditions and personnel monitoring (2) Provision of shelters to protect

workers during rest periods (3) Maintenance of body heat at normal levels by wearing

adequate layers of clothing (4) Training site personnel to recognize and treat cold stress

(5) Frequent warm up breaks (6) Acclimation

Heat Stress

Wearing personal protective equipment puts a field worker at considerable risk of

developing heat stress This can result in health effects ranging from transient heat

fatigue to serious illness or death Heat stress is an aggregate of all the heat factors both

internal and external that work on the body

FOR WR GRACE amp Co - CONN MWP_DOCSNON2000F[NALP11ASEIRI0225600WPO ATT B1-18 HSI GCOTfanS IHC

External factors that contribute to heat stress include ambient air temperature

radiant temperature air velocity and the relative humidity Internal factors include

metabolic heat body core temperature respiration rate and acclimation

Early symptoms of heat stress include mental confusion and the inability to

concentrate heat rash and heat cramps (muscle spasms andor pain in hands feet and

abdomen) Acute and chronic heat stress impacts a workers temperament causing

impulsive aggressive and violent acts to be committed by the victim Signs of heat

exhaustion include pale cool moist skin heavy sweating dizziness nausea and fainting

Heat stroke is the most serious form of heat stress Immediate action must be taken to

cool the body and prevent serious injury Competent medical help must be obtained

Signs include red hot dry skin lack of or reduced perspiration nausea dizziness and

confusion strong rapid pulse and coma The case-fatality of heat-stroke and heat

exhaustion is probably no lower than 10 percent Because heat stress is one of the most

common (and potentially serious) illnesses at field sites regular monitoring and other

preventative precautions are vital

To monitor for heat stress measure

(1) Heart rate mdash Count the radial pulse during a 30-second period as early as possible during rest periods If the heart exceeds 110 beats per minute at the beginning of the rest period shorten the next work cycle by one-third and keep the rest period the same If the heart rate still exceeds 110 beats per minute at the next rest period shorten the following work cycle by one-third again

(2) Oral temperatures mdash Use an oral thermometer to measure the oral temperature at the end of the work period (before drinking) If oral temperature exceeds 996 degrees F shorten the next work cycle by one-third without changing the rest period Repeat if necessary Do not permit a worker to wear PPE when the workers oral temperature is above 1006 degrees F

(3) Body weight mdash If possible measure weight at the beginning and end of each day to see if enough fluids are being taken during the day The body water loss should not exceed 15 percent of total body weight in a work day

FOR WR GRACE amp Co - CONN M wp_DocsN099v2oooFiNALpHASFinjo22si6oowpD A I I B1-19 HSI GeoTrans inc

Prevention of heat stress can be achieved by

(1) Modification of work schedules as required by site conditions and personnel monitoring

(2) Provision of shelters or shaded areas to protect workers during rest periods

(3) Maintenance of body fluids at normal levels by drinking cold water and

(4) Training Site Personnel to recognize and treat heat stress signs

(5) Acclimation

- Oxygen content (should be between 195 to 235 percent)

- Combustible gases (should be less than 10 percent of the lower explosive limit)

- Potential toxic air contaminants

bull The space should be tested at all levels (top middle and bottom) and in all areas where work may occur The atmosphere within the space must not be hazardous whenever an employee is inside the space

bull If forced-air ventilation is used the following conditions apply

mdash Ventilation should not be used to control continuous sources of hazardous contaminants

- There must be a clean source of air that will not increase the hazard within the space

bull The entrant shall document on Form CS-2 that the space is safe for entry and that preshyentry measures required by this SWP have been taken The form shall be made available to each employee entering the space and shall be kept at the work site until completion of confined space work The certificate will then become part of the permanent project file

The atmosphere within the confined space must be tested periodically while entrants are within the

confined space Frequency of testing shall be every 30 minutes during the first 2 hours then hourly

afterwards when entrants are in the confined space If at any time during occupancy a hazardous

atmosphere is detected the entrants shall leave the space immediately The space shall then be evaluated

to determine how the hazardous atmosphere developed and measures shall be implemented to protect

employees from the hazardous atmosphere before any subsequent entry Re-entry shall not be allowed

until atmospheric testing demonstrates acceptable conditions

When changes in the use or configuration of a non-permit-required space cannot be eliminated or

controlled the SSC shall re-evaluate the space and if necessary reclassify it as a permit-required

confined space

Menzie-Cura amp Associates Inc adopts the HSI Geotrans Health and Safety Plan (HSP) The HSP contains a hazard assessment for contaminants found at the Site historically In addition to HSI Geotrans HSP Menzie-Cura amp Associates Inc personnel will following the boating safety procedures identified here when sampling in Sinking Pond and the reference pond

This work will take place in a small boat (possibly using a gasoline run outboard motor) All personnel will wear a United States Coast Guard approved personal flotation device (PFD) whenever working from the boat No smoking is allowed at any time in the boat or within 50 feet of it during refueling The Captain will be named at a later date At the Captains discretion he or she can modify or cancel any on-board operation for safety reasons Such reasons may include but are not limited to weather condition of boat or motor condition of sampling equipment or preparedness of personnel All personnel working on board will follow his or her orders

We will follow small boat safety procedures The boats transom or seats will contain a plate which describes the total weight capacity and other limitations of the particular boat used We will not exceed these The boats equipment will include motor full spare gasoline tank oars installed oar locks Danforth anchor 50 feet of half inch nylon anchor line terminated in three feet of half inch galvanized chain a metered and weighted line to estimate depth personal flotation devices (PFDs) for everyone on board a two quart canteen of drinking water (otherwise there should be no food on-board) and a cell phone

Personnel on board will each carry a belted and sheathed jack knife or rigging knife On-board personnel will be aware of the position of their bodies relative to coiled or faired lines or lines under tension Especially do not put hands or feet in any basket containing a faired line or sit upon a coiled deck line Always position yourself to one side of a line under tension Never position yourself behind a line under tension or between such a line and the gunnel of the boat or any other immovable object During over the side operations lower all lines Never let a weighted line free fall The most common way to drown is to go over the side with a free falling anchor or equipment line tangled around a leg arm or neck Grab samplers are not intended to free fall they are designed to be lowered It may be necessary to let certain samplers free fall a short distance (ie several feet) from above the bottom Lower them to that height above bottom Always know the depth to bottom before deploying equipment

Generally stay seated in the boat It is sometimes necessary to stand when deploying equipment Do this keeping your center of gravity as low as possible and as near the center line of the boat as possible Before standing or changing your position in the boat announce your intentions to all on-board

1123 SITE EMERGENCY PROCEDURES

FireExplosion

A fire that cannot be readily extinguished with one ten pound fire extinguisher

will be considered major and may require evacuation of Site personnel to safe areas The

SSO will call the fire department and will coordinate with fire emergency personnel as to

the selection of protective clothing and equipment as well as the use of proper fire

FOR wR GRACE amp Co - CONN M Wgt DOCSN0992000FINA1 PHASE I RIX02251600 wpo APR D1-6 HSI GeoTrans inc

fighting techniques The air downwind from any fireexplosion is to be monitored

immediately in order to protect workers and the nearby community If so required by the

air monitoring results the Vapor Emission Response Plan will be placed into effect If

personal injuries result from any fire or explosion the procedures outlined in the Personal

Injury Response Plan will be followed

Hazardous Spill

Any release or threat of release occurring during the work that constitutes an

emergency or may present an immediate threat to public health welfare or the

environment will be reported by the SSO or clients representative to the government

parties In the event of a spill the two main goals are to contain the spill as much as

possible and to minimize vapor emissions In order to accomplish these goals the

following equipment should be available at the Site

(1) an empty container

(2) polyethylene sheets

(3) absorbent materials and

(4) a shovel

Vapor Emission Response Plan

If any of the following conditions are identified at the Site exclusion zone

boundary all activities must be halted

(1) organic levels observed on air monitoring equipment of unknown

constituents are greater than 5 ppm above known background or

action levels requiring evacuation are reached or

(2) LEL levels greater than 10

If following the cessation of activities or as the result of an emergency

such as that described in the section on FireExplosion any of the above levels

persist downwind from the Site at the boundary of the exclusion zone then this

FOR W R GRACE amp Co - CONN MWP_DOCSW0992000F1NALPHASEIRI022SI600WPD APP D1-7 HSI GfiOTfanS lllC

Emergency Plan will automatically be placed into effect Upon activation of the

Emergency Plan the nearest perimeter of the closest downwind residential or

commercial property will immediately be monitored If organic levels from an

unknown source approach 5 ppm the local police authorities or property owner

will immediately be contacted by the SSO or clients representative and advised of

the situation

Personal Injury Response Plan

Accidents - Depending on the seriousness of the injury treatment may be

given at the Site by the SSO For more serious injuries additional assistance by

ambulance may be required at the Site or the victim may have to be treated at a

medical facility The SSO will assess the seriousness of the injury and will

consult by phone with a physician if necessary The SSO will file a complete

incident report with the Office Health and Safety Officer and the Project

Coordinator as soon as possible

Chemical Overexposure - Personnel including unauthorized personnel

that suffer chemical overexposure shall be treated in the following manner

bull Skin Contact Remove contaminated clothing Wash immediately with water Use soap if available

bull Inhalation Remove from contaminated atmosphere Artificial respiration if necessary Transport to hospital

113 BACKGROUND INFORMATION

Overall Risk is High Moderate _

Low Unknown

1131 FACILITY DESCRIPTION

The Site is located in Acton and Concord Massachusetts on Independence Road

The Grace property is bordered by residential property on the northwest east and west

and industrial properties to the south and northeast Fort Pond Brook bounds the Grace

property to the northwest and the Assabet River bounds the Grace property to the

southeast The Assabet well field which supplies water for the Town of Acton is located

southwest of the Grace property Two inactive sand and gravel pits Massachusetts

Broken Stone Pit and Assabet Sand and Gravel are located south of the Grace property

Former occupants of the Site include American Cyanamid Company which

manufactured explosives and Dewey amp Almy Chemical Company Dewey amp Almy

acquired the property in 1946 and manufactured synthetic rubber container sealant

products An organic chemical plant which produced latex products plasticizers and

resins commenced operation in 1949 A paper battery separator production facility was

constructed in 1951

Grace acquired Dewey and Almy in 1954 and chemical operations were

continued at the Site Grace produced materials used to make concrete and organic

chemicals container sealing compounds latex products and paper and plastic battery

separators Wastewater and solid industrial wastes from these operations were disposed

in several on-site lagoons and an on-site landfill In addition the by-products of some

chemical processes were disposed of in the Slowdown Pit located in the central portion of

the property (Figure 1-2) Discharge to these areas ceased in 1980 Production of organic

chemicals was discontinued in 1982 A small distribution center for concrete additives

(Grace Construction Products) was moved to another location in September 1996 A

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINAL PHASE I RI022S1600 WPD APPD1-11 HSI GeOTianS lllC

second battery separator plant (Daramic) was constructed in 1979 and operations there

continued until 1991 The Daramic facility has not been considered part of the Site All

buildings with the exception of the building associated with the ARS have been

demolished

In 1978 groundwater contamination consisting mainly of 11-dichloroethene

(VDC) and lesser amounts of vinyl chloride ethylbenzene and benzene was detected in

two Acton municipal supply wells Assabet 1 and Assabet 2 located southwest of the

Grace property This discovery prompted a series of investigations which culminated in

the installation of the ARS beginning in late 1983 The ARS is a network of eleven

extraction wells designed to contain and cleanup contaminated groundwater and it is

currently operational

Following installation of the ARS extensive investigations were done by Grace

on in beneath and immediately surrounding the source areas to determine the nature and

extent of contamination by waste disposal practices Following a complete engineering

analysis of cleanup and remedial alternatives for the sources referred to as Operable

Unit-1 (OU-1) a remedy was selected for OU-1 Implementation of the remedy began in

November 1994 and was completed in July 1997 Following completion of the OU-1

remedy a comprehensive review of the groundwater quality and groundwater flow

conditions observed at the Site since the early 1980s and an evaluation of the

effectiveness of the ARS to contain and remediate groundwater affected by the Site was

done in the Initial Site Characterization Report (ISCR) (HSI GeoTrans 1998) While

data reviewed in the ISCR indicated that most areas of the Site containing groundwater

contamination are within the ARS capture zone and that contaminant concentrations in

most wells located outside of the capture zone have decreased significantly since 1984

uncertainties remain regarding the flow of groundwater and the distribution of

contaminants in certain areas of the Site The RIFS is designed to evaluate the extent of

FOR WR GRACE amp Co - CONN M wp_DocsN0992ooofiNALpnASEiRno225i6oowpo APPD1-12 HSI GeoTrans inc

groundwater contamination on- and off-Site and to determine whether additional remedial

measures are necessary to ensure accelerated restoration of the groundwater affected by

the Site to a fully usable condition

The Site property is now inactive as a manufacturing center The perimeter is

identified but due to the size is not secured Access to the Site is controlled through

locked gated entrances and exits The surrounding area is heavily wooded and restricts

the entrance of vehicles to the Site

1132 EXISTING CHEMICAL DATA

The existing historical chemical data for the Site has been compiled through a

thorough review of past activities at the Site and a review of the Site electronic database

For the purposes of this HSP only data collected after the completion of the source

removal activities will be used to evaluate health and safety concerns at the Site The

electronic database was queried in March of 1999 to determine the maximum

concentration and frequency of compounds detected in groundwater at the Site since

January 1 1996 (Table 1-1)

The volatile organic compounds (VOCs) with the highest frequency of detections

and maximum detection shown in parentheses at the Site are benzene (8600 ugL)

VDC (1000 ugL) and vinyl chloride (280 ugL) The semi-volatile organic compounds

(SVOCs) with the highest frequency of detections and maximum detection shown in

parenthesis at the Site are diethlyphthalate (110 ugL) bis(2-ethylhexyl)phthalate (120

ugL) and bis(2- chloroethyl)ether (41 ugL) The inorganic compounds with the highest

frequency of detections and maximum detection shown in parenthesis at the Site are

arsenic (13000 ugL) aluminum (42000 yUgL) nickel (890 ugL) and cadmium (16

ugL) The groundwater data collected indicate that pesticides and PCBs are not a

concern at the Site (HSI GeoTrans 1998) Therefore no pesticides or PCBs will be

monitored for during work tasks at the Site

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINM PHASE I RI0225I600 wro APPD1-13 HSI GeOTfanS lllC

Other compounds have been detected at varying concentrations and at a wide

range of frequencies at the Site Because such a wide range of VOCs SVOCs and

inorganics have been detected at the Site it was necessary to screen these compounds for

potential health hazards and exposure risks A full discussion of the potential health

hazard and exposure risk screening is provided in Attachment A Attachment A also

includes tables which indicate the physical description and associated health hazards for

each compound detected at the Site (Attachment A Table A-l) the exposure limits and

monitoring properties for each compound detected at the Site (Attachment A Table A-2)

compounds with gas and vapor exposure limits less than 5 ppm (Attachment A Table Ashy

3) compounds with particulate exposure limits less than 1 mgm3 (Attachment A Table

A-4) and a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) (Attachment A Table A-5)

Based on the screening discussed in Attachment A it was determined that the

compounds listed in Table 1-2 are contaminants of monitoring concern These

compounds have vapor exposure limits less than 5 ppm have been detected at least four

times and have a maximum detection concentration greater than 10 ppb (ugL) The

compounds found at the highest frequency and with greatest maximum concentration at

the Site benzene VDC and vinyl chloride are included in the list of compounds of

monitoring concern and comprise the lowest exposure limits Therefore benzene VDC

and vinyl chloride will be used as indicator compounds for vapor monitoring during work

tasks No dust monitoring will be conducted Work practices and investigation derived

waste (IDW) management practices will be used that will minimize the potential for

contaminated soil to be suspended in breathing space air Because vapor monitoring

action levels are lower than LEL action levels (10 percent of the LEL) no LEL

monitoring is required aside from that associated with confined space entry of the

recovery well vaults

POTENTIAL HEALTH HAZARD AND EXPOSURE RISK SCREENING

FOR WR GRACE amp Co - CONN M wp_Docswo992oooFiNALpiiASE i wo225 i6oo wro ATTA1-1 HSI GeoTrans inc

POTENTIAL HEALTH HAZARD AND EXPOSURE RISK SCREENING

The historical chemical data for the Site has been compiled through a thorough

review of past activities at the Site and a review of the Site electronic database For the

purposes of this HSP only data collected after the completion of the source removal

activities will be used to evaluate health and safety concerns at the Site The electronic

database was queried in March of 1999 to determine the maximum concentration and

frequency of compounds detected in groundwater at the Site since January 1 1996 (see

Table 1-1)

A hazard screening evaluation was performed for each compound identified in the

database search described above Table A-l indicates the associated health hazards

(exposure routes symptoms and target organs) for compounds detected at the Site and

the physical description (eg color solidliquidgas phase odor) Compounds for which

the NIOSH guide (NIOSH 1998) did not contain health hazard or physical description

information are shown with no information in the table row Some physical descriptions

for compounds were gathered from other sources (See Table A-l citation notes)

Table A-2 provides the exposure limits a summary of daily time weighted

average (Per Day TWA) and the 15 minute short term (15 min STEL) ceiling and

immediately dangerous to life or health (IDLH) exposure limits The limits shown are the

most stringent quantified exposure limits put forth by OSHA NIOSH and ACGIH for

each exposure limit category

Compounds that NIOSH considers to be potential occupational carcinogens are

designated with a check in the CA box in Tables A-2 A-3 and A-4 NIOSH usually

recommends that occupational exposures to carcinogens be limited to the lowest feasible

concentration (LFC) Those compounds NIOSH has identified as potential carcinogens

but has not quantified recommended exposure limits (REL) are designated with LFC

under the Most Stringent Exposure Limit column in Attachment A Table A-3 The

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINA1 PHASE I RT02251600 WPD ATT A1 -2 HSI GeOTiaHS lllC

ACGIH has categorized compounds into five carcinogenicity groups based on available

information Al for confirmed human carcinogens A2 for suspected human carcinogens

A3 for confirmed animal carcinogen with unknown relevance to humans A4 for not

classifiable as a human carcinogen and A5 for compounds not suspected as a human

carcinogen The carcinogenicity category for compounds which ACGIH has designated

is also shown in Tables A-2 A-3 and A-4

The compounds that have potential air monitoring concerns for this Site are those

compounds designated in Table A-3 with LFC an ACGIH carcinogenicity of Al or A2

a gas and vapor exposure limit of 5 ppm or less or with a suspended-in-air particulate

exposure limit of 1 mgm3 or less Tables A-3 and A-4 summarize the most stringent gas

and vapor and particulate exposure limits for these compounds respectively

The compounds with gas and vapor exposure limits of 5 ppm or less which were

detected at low frequency and low concentration (three or fewer times and at a

concentration less than 10 ppb (^gL)) are not considered to be of monitoring concern

(Table A-3) The remaining compounds in Table A-3 have only been detected at

locations where the concentration of benzene VDC and vinyl chloride represent the

majority of the total concentration of chemicals with monitoring concerns Because the

exposure limits for benzene VDC and vinyl chloride are low and these compounds make

up the majority of contamination in groundwater at the Site monitoring for benzene

VDC and vinyl chloride is a conservative means to evaluate work task exposure risks

which establish action level PPE modifications In order to screen for the compounds in

Table A-3 detector tubes or other compound specific monitoring devices for the indicator

parameters (benzene VDC and vinyl chloride) will be used according to action levels

associated with the tasks to be performed

The compounds with a suspended-in-air particulate exposure limit of 1 mgm3 or

less which were detected at low frequency and low concentration (three or fewer times

and at a concentration less than 10 ppb (^gL)) are not considered to be of monitoring

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FlNALPHAbElRI02251600 WO ATTA1-3 HSI GCOTfanS 1HC

concern (Table A-4) Work practices and investigation derived waste (1DW)

management practices will be used that will minimize the potential for contaminated soil

to be suspended in breathing space air above the exposure levels for the remaining

compounds

Table A-5 is a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) Because vapor monitoring action

levels are lower than LEL action levels (10 percent of the LEL) no LEL monitoring is

required

AIR MONITORING

Air monitoring shall be used during hazardous waste and contamination

investigations to identify and quantify airborne levels of hazardous substances in order to

determine the appropriate level of employee protection needed on site As a first step air

monitoring shall be conducted to identify any IDLH and other dangerous situations such

as the presence of flammable atmospheres oxygen-deficient environments toxic levels of

airborne contaminants and radioactive materials As a minimum periodic monitoring

shall be conducted when

(1) Work begins on a different portion of the site

(2) Contaminants other than those previously identified are being handled

(3) A different type of operation is initiated or

(4) Workers are handling leaking containers or working in areas with obvious liquid contamination

OSHA regulations regarding decontamination at hazardous waste sites are

incorporated into this plan and include the following

(1) A decontamination procedure shall be developed and implemented before workers or equipment can go into areas where exposure to contaminants may occur

(2) Standard operating procedures shall be developed to minimize the exposure to contaminants

(3) Decontamination shall be performed in areas that will minimize the exposure of uncontaminated workers or equipment to contaminated workers or equipment

(4) All employees leaving a contaminated area shall be decontaminated all clothing and equipment leaving a contaminated area shall be appropriately disposed of or decontaminated

(5) Decontamination measures shall be monitored by the Safety Officer and shall be modified to correct any deficiencies

(6) All equipment and solvents used for decontamination shall be disposed of properly

(7) Protective clothing and equipment shall be decontaminated cleaned laundered maintained or replaced as needed to maintain their effectiveness

(8) Impermeable protective clothing which contacts or is likely to have contacted hazardous substances shall be decontaminated before being removed by the worker

(9) Employees whose non-impermeable clothing becomes wetted with hazardous substances shall immediately remove that clothing and proceed to shower The clothing shall be disposed of or decontaminated before it is removed from the work zone

PERSONAL INJURY RESPONSE PLAN

Accidents

Physical injuries can range from a sprained ankle to a compound fracture or from a

minor cut to massive bleeding Depending on the seriousness of the injury treatment

may be given at the site by the Site Safety Officer For more serious injuries additional

assistance by ambulance may be required at the site or the victim may have to be treated

at a medical facility The Safety Officer will assess the seriousness of the injury and will

consult by phone with a physician if necessary

Chemical Exposure

Personnel including unauthorized personnel that suffer chemical overexposure shall

be treated in the following manner

bull Skin Contact Remove contaminated clothing Wash immediately with water Use soap if available

bull Inhalation Remove from contaminated atmosphere Artificial respiration is necessary Transport to hospital

bull Ingestion Never induce vomiting on an unconscious person Also never induce vomiting when acids alkalis or petroleum products are suspected Contact the poison control center

bull Ionizing Radiation Normal background 001 to 005 mRhr If less than 1 mRhr continue investigation with caution If greater than 1 mRhr evacuate site

These personnel shall be observed by the Site Safety Officer to ascertain whether

there are any symptoms resulting from overexposure If there is any visible manifestation

of overexposure such as skin irritation Project Personnel should be examined by a

physician All episodes of obvious chemical contamination are to be reviewed by the Site

Safety Officer in order to determine whether changes are needed in work procedures

Cold Stress

Persons working outdoors in temperatures at or below freezing may be frostbitten

Exposure to extreme cold for a short time may cause severe injury to the surface of the

body or result in profound generalized cooling causing death Areas of the body that

have a high surface-area-to-volume ratio such as fingers toes and ears are the most

susceptible Two factors influence the development of a cold injury ambient temperature

and the velocity of the wind Wind chill is used to describe the chilling effect of moving

air in combination with low temperature For instance 10degF with a wind of 15 mph is

equivalent in chilling effect to still air at -18degF

As a general rule the greatest incremental increase in wind chill occurs when a wind

of 5 mph increases to 10 mph Additionally water conducts heat 240 times faster than

air Thus the body cools suddenly when chemical-protective equipment is removed if the

clothing underneath is soaked with perspiration Local injury resulting from cold is

included in the generic term frostbite There are several degrees of damage

Systemic hypothermia is caused by exposure to freezing or rapidly dropping

temperature Its symptoms are usually exhibited in five stages (1) shivering (2) apathy

listlessness sleepiness and (sometimes) rapid cooling of the body to less than 95 degF (3)

unconsciousness glassy stare slow pulse and slow respiratory rate (4) freezing of the

extremities and finally (5) death

Prevention of Cold Stress can be achieved by (1) Modification of work schedules as

required by site conditions and personnel monitoring (2) Provision of shelters to protect

workers during rest periods (3) Maintenance of body heat at normal levels by wearing

adequate layers of clothing (4) Training site personnel to recognize and treat cold stress

(5) Frequent warm up breaks (6) Acclimation

Heat Stress

Wearing personal protective equipment puts a field worker at considerable risk of

developing heat stress This can result in health effects ranging from transient heat

fatigue to serious illness or death Heat stress is an aggregate of all the heat factors both

internal and external that work on the body

FOR WR GRACE amp Co - CONN MWP_DOCSNON2000F[NALP11ASEIRI0225600WPO ATT B1-18 HSI GCOTfanS IHC

External factors that contribute to heat stress include ambient air temperature

radiant temperature air velocity and the relative humidity Internal factors include

metabolic heat body core temperature respiration rate and acclimation

Early symptoms of heat stress include mental confusion and the inability to

concentrate heat rash and heat cramps (muscle spasms andor pain in hands feet and

abdomen) Acute and chronic heat stress impacts a workers temperament causing

impulsive aggressive and violent acts to be committed by the victim Signs of heat

exhaustion include pale cool moist skin heavy sweating dizziness nausea and fainting

Heat stroke is the most serious form of heat stress Immediate action must be taken to

cool the body and prevent serious injury Competent medical help must be obtained

Signs include red hot dry skin lack of or reduced perspiration nausea dizziness and

confusion strong rapid pulse and coma The case-fatality of heat-stroke and heat

exhaustion is probably no lower than 10 percent Because heat stress is one of the most

common (and potentially serious) illnesses at field sites regular monitoring and other

preventative precautions are vital

To monitor for heat stress measure

(1) Heart rate mdash Count the radial pulse during a 30-second period as early as possible during rest periods If the heart exceeds 110 beats per minute at the beginning of the rest period shorten the next work cycle by one-third and keep the rest period the same If the heart rate still exceeds 110 beats per minute at the next rest period shorten the following work cycle by one-third again

(2) Oral temperatures mdash Use an oral thermometer to measure the oral temperature at the end of the work period (before drinking) If oral temperature exceeds 996 degrees F shorten the next work cycle by one-third without changing the rest period Repeat if necessary Do not permit a worker to wear PPE when the workers oral temperature is above 1006 degrees F

(3) Body weight mdash If possible measure weight at the beginning and end of each day to see if enough fluids are being taken during the day The body water loss should not exceed 15 percent of total body weight in a work day

FOR WR GRACE amp Co - CONN M wp_DocsN099v2oooFiNALpHASFinjo22si6oowpD A I I B1-19 HSI GeoTrans inc

Prevention of heat stress can be achieved by

(1) Modification of work schedules as required by site conditions and personnel monitoring

(2) Provision of shelters or shaded areas to protect workers during rest periods

(3) Maintenance of body fluids at normal levels by drinking cold water and

(4) Training Site Personnel to recognize and treat heat stress signs

(5) Acclimation

Terra Tech Inc Safe Work Practices Issue Date July 1998 Non-Permit-Required Confined Space Entry Practices Revision No 1 SWPNo 6-24 Page 1

NON-PERMIT-REQUIRED CONFINED SPACE ENTRY PRACTICES

The following safe work practices (SWP) apply to entry into confined spaces classified as non-permitshy

required The confined space must conform to the definition of a non-permit-required confined space as

discussed in the Confined Space Entry Program (see Document Control No 2-5 in Volume I) Entry into

spaces classified as non-permit-required are preferable over entry into permit-required spaces When

feasible efforts shall be directed to prepare confined spaces so they meet the definitions of non-permitshy

required confined space

If any of the procedures discussed in this SWP cannot be completed or an unanticipated hazard is

identified the non-permit-required status of the space will be revoked until the space is re-evaluated and

reapproved as a non-permit-required space by a technically qualified individual such as a Tetra Tech

health and safety specialist

Non-permit-required confined space entry procedures before entry into the space are listed below

bull The project manager and the site safety coordinator (SSC) should be notified of the need to enter into a confined space This notification must allow sufficient time to assemble necessary safety equipment

bull A blank Preparation and Testing of Non-Permit Required Confined Space form (Form CS-2) must be obtained (see Volume HI)

bull The necessary safety equipment can include but is not limited to atmospheric testing meters and devices a mechanical ventilator and a ladder for entry and exit

bull All equipment to be used during entry must be tested and inspected before use Atmospheric testing equipment shall be calibrated in accordance with the manufacturers instructions to ensure proper operation Calibration parameters shall be documented in the field logbook and the equipment will be tagged with a label specifying these parameters

bull Hazardous conditions associated with the removal of the entrance cover should be eliminated before opening the confined space After removal of the entrance cover the opening should be promptly barricaded by a railing temporary cover or other temporary barrier to prevent employees and equipment from accidentally falling through the opening

bull The internal atmosphere should be tested for the following conditions in the order given

- Oxygen content (should be between 195 to 235 percent)

- Combustible gases (should be less than 10 percent of the lower explosive limit)

- Potential toxic air contaminants

bull The space should be tested at all levels (top middle and bottom) and in all areas where work may occur The atmosphere within the space must not be hazardous whenever an employee is inside the space

bull If forced-air ventilation is used the following conditions apply

mdash Ventilation should not be used to control continuous sources of hazardous contaminants

- There must be a clean source of air that will not increase the hazard within the space

bull The entrant shall document on Form CS-2 that the space is safe for entry and that preshyentry measures required by this SWP have been taken The form shall be made available to each employee entering the space and shall be kept at the work site until completion of confined space work The certificate will then become part of the permanent project file

The atmosphere within the confined space must be tested periodically while entrants are within the

confined space Frequency of testing shall be every 30 minutes during the first 2 hours then hourly

afterwards when entrants are in the confined space If at any time during occupancy a hazardous

atmosphere is detected the entrants shall leave the space immediately The space shall then be evaluated

to determine how the hazardous atmosphere developed and measures shall be implemented to protect

employees from the hazardous atmosphere before any subsequent entry Re-entry shall not be allowed

until atmospheric testing demonstrates acceptable conditions

When changes in the use or configuration of a non-permit-required space cannot be eliminated or

controlled the SSC shall re-evaluate the space and if necessary reclassify it as a permit-required

confined space

Potential Health Effects

Inhalation Corrosive Inhalation of vapors can cause coughing choking inflammation of the nose throat and upper respiratory tract and in severe cases pulmonary edema circulatory failure and death Ingestion Corrosive Swallowing hydrochloric acid can cause immediate pain and bums of the mouth throat esophagus and gastrointestinal tract May cause nausea vomiting and diarrhea Swallowing may be fatal Skin Contact Corrosive Can cause redness pain and severe skin burns Concentrated solutions cause deep ulcers and discolor skin Eye Contact Corrosive Vapors are irritating and may cause damage to the eyes Contact may cause severe burns and permanent eye damage Chronic Exposure Long-term exposure to concentrated vapors may cause erosion of teeth Long term exposures seldom occur due to the corrosive properties of the acid Aggravation of Pre-existing Conditions Persons with pre-existing skin disorders or eye disease may be more susceptible to the effects of this substance

4 First Aid Measures

Inhalation Remove to fresh air If not breathing give artificial respiration If breathing is difficult give oxygen Get medical attention immediately Ingestion DO NOT INDUCE VOMITING Give large quantities of water or milk if available Never give anything by mouth to an unconscious person Get medical attention immediately Skin Contact hi case of contact immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes Wash clothing before reuse Thoroughly clean shoes before reuse Get medical attention immediately

HYDROCHLORIC ACID 33 - 40 httpwwwjtbakercommsdsh3880htm

Eye Contact Immediately flush eyes with plenty of water for at least 15 minutes lifting lower and upper eyelids occasionally Get medical attention immediately

5 Fire Fighting Measures

Fire Extreme heat or contact with metals can release flammable hydrogen gas Explosion Not considered to be an explosion hazard Fire Extinguishing Media If involved in a fire use water spray Neutralize with soda ash or slaked lime Special Information In the event of a fire wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode Structural firefighters protective clothing is ineffective for fires involving hydrochloric acid Stay away from ends of tanks Cool tanks with water spray until well after fire is out

6 Accidental Release Measures

Ventilate area of leak or spill Wear appropriate personal protective equipment as specified in Section 8 Isolate hazard area Keep unnecessary and unprotected personnel from entering Contain and recover liquid when possible Neutralize with alkaline material (soda ash lime) then absorb with an inert material (e g vermiculite dry sand earth) and place in a chemical waste container Do not use combustible materials such as saw dust Do not flush to sewer US Regulations (CERCLA) require reporting spills and releases to soil water and air in excess of reportable quantities The toll free number for the US Coast Guard National Response Center is (800) 424-8802

J T Baker NEUTRASORB(tm) or TEAM(tm) Low Na+ acid neutralizers are recommended for spills of this product

7 Handling and Storage

Store in a cool dry ventilated storage area with acid resistant floors and good drainage Protect from physical damage Keep out of direct sunlight and away from heat water and incompatible materials Do not wash out container and use it for other purposes When diluting the acid should always be added slowly to water and in small amounts Never use hot water and never add water to the acid Water added to acid can cause uncontrolled boiling and splashing When opening metal containers use non-sparking tools because of the possibility of

mdash- hydrogen gas being present Containers of this material may be hazardous when empty since they retain product residues (vapors liquid) observe all warnings and precautions listed for the product

8 Exposure ControlsPersonal Protection

Airborne Exposure Limits -OSHA Permissible Exposure Limit (PEL) 5 ppm Ceiling -ACGIH Threshold Limit Value (TLV) 5 ppm Ceiling

Ventilation System A system of local andor general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source preventing dispersion of it into the general work area Please refer to the ACGIH document Industrial Ventilation A Manual of Recommended Practices most recent edition for details Personal Respirators (NIOSH Approved) If the exposure limit is exceeded a full facepiece respirator with an acid gas cartridge may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier whichever is lowest For emergencies or instances where the exposure levels are not known use a full-facepiece positive-pressure air-supplied respirator WARNING Air purifying respirators do not protect workers in oxygen-deficient atmospheres Skin Protection Rubber or neoprene gloves and additional protection including impervious boots apron or coveralls as needed in areas of unusual exposure to prevent skin contact Eye Protection Use chemical safety goggles andor a full face shield where splashing is possible Maintain eye wash fountain and quick-drench facilities in work area

Menzie-Cura amp Associates Inc adopts the HSI Geotrans Health and Safety Plan (HSP) The HSP contains a hazard assessment for contaminants found at the Site historically In addition to HSI Geotrans HSP Menzie-Cura amp Associates Inc personnel will following the boating safety procedures identified here when sampling in Sinking Pond and the reference pond

This work will take place in a small boat (possibly using a gasoline run outboard motor) All personnel will wear a United States Coast Guard approved personal flotation device (PFD) whenever working from the boat No smoking is allowed at any time in the boat or within 50 feet of it during refueling The Captain will be named at a later date At the Captains discretion he or she can modify or cancel any on-board operation for safety reasons Such reasons may include but are not limited to weather condition of boat or motor condition of sampling equipment or preparedness of personnel All personnel working on board will follow his or her orders

We will follow small boat safety procedures The boats transom or seats will contain a plate which describes the total weight capacity and other limitations of the particular boat used We will not exceed these The boats equipment will include motor full spare gasoline tank oars installed oar locks Danforth anchor 50 feet of half inch nylon anchor line terminated in three feet of half inch galvanized chain a metered and weighted line to estimate depth personal flotation devices (PFDs) for everyone on board a two quart canteen of drinking water (otherwise there should be no food on-board) and a cell phone

Personnel on board will each carry a belted and sheathed jack knife or rigging knife On-board personnel will be aware of the position of their bodies relative to coiled or faired lines or lines under tension Especially do not put hands or feet in any basket containing a faired line or sit upon a coiled deck line Always position yourself to one side of a line under tension Never position yourself behind a line under tension or between such a line and the gunnel of the boat or any other immovable object During over the side operations lower all lines Never let a weighted line free fall The most common way to drown is to go over the side with a free falling anchor or equipment line tangled around a leg arm or neck Grab samplers are not intended to free fall they are designed to be lowered It may be necessary to let certain samplers free fall a short distance (ie several feet) from above the bottom Lower them to that height above bottom Always know the depth to bottom before deploying equipment

Generally stay seated in the boat It is sometimes necessary to stand when deploying equipment Do this keeping your center of gravity as low as possible and as near the center line of the boat as possible Before standing or changing your position in the boat announce your intentions to all on-board

the selection of protective clothing and equipment as well as the use of proper fire

FOR wR GRACE amp Co - CONN M Wgt DOCSN0992000FINA1 PHASE I RIX02251600 wpo APR D1-6 HSI GeoTrans inc

fighting techniques The air downwind from any fireexplosion is to be monitored

immediately in order to protect workers and the nearby community If so required by the

air monitoring results the Vapor Emission Response Plan will be placed into effect If

personal injuries result from any fire or explosion the procedures outlined in the Personal

Injury Response Plan will be followed

Hazardous Spill

Any release or threat of release occurring during the work that constitutes an

emergency or may present an immediate threat to public health welfare or the

environment will be reported by the SSO or clients representative to the government

parties In the event of a spill the two main goals are to contain the spill as much as

possible and to minimize vapor emissions In order to accomplish these goals the

following equipment should be available at the Site

(1) an empty container

(2) polyethylene sheets

(3) absorbent materials and

(4) a shovel

Vapor Emission Response Plan

If any of the following conditions are identified at the Site exclusion zone

boundary all activities must be halted

(1) organic levels observed on air monitoring equipment of unknown

constituents are greater than 5 ppm above known background or

action levels requiring evacuation are reached or

(2) LEL levels greater than 10

If following the cessation of activities or as the result of an emergency

such as that described in the section on FireExplosion any of the above levels

persist downwind from the Site at the boundary of the exclusion zone then this

FOR W R GRACE amp Co - CONN MWP_DOCSW0992000F1NALPHASEIRI022SI600WPD APP D1-7 HSI GfiOTfanS lllC

Emergency Plan will automatically be placed into effect Upon activation of the

Emergency Plan the nearest perimeter of the closest downwind residential or

commercial property will immediately be monitored If organic levels from an

unknown source approach 5 ppm the local police authorities or property owner

will immediately be contacted by the SSO or clients representative and advised of

the situation

Personal Injury Response Plan

Accidents - Depending on the seriousness of the injury treatment may be

given at the Site by the SSO For more serious injuries additional assistance by

ambulance may be required at the Site or the victim may have to be treated at a

medical facility The SSO will assess the seriousness of the injury and will

consult by phone with a physician if necessary The SSO will file a complete

incident report with the Office Health and Safety Officer and the Project

Coordinator as soon as possible

Chemical Overexposure - Personnel including unauthorized personnel

that suffer chemical overexposure shall be treated in the following manner

bull Skin Contact Remove contaminated clothing Wash immediately with water Use soap if available

bull Inhalation Remove from contaminated atmosphere Artificial respiration if necessary Transport to hospital

bull Ingestion Never induce vomiting on an unconscious person Also never induce vomiting when acids alkalis or petroleum products are suspected Contact the poison control center

These personnel shall be observed by the SSO to ascertain whether there

are any symptoms resulting from overexposure If there is any visible

manifestation of overexposure such as skin irritation Project Personnel should be

FOR WR GRACE amp Co - CONN MWP DOCSN0992000F1NAL PHASE I RI02251600 WPD APP D1-8 HSI GeOTfanS IRC

examined by a physician All episodes of obvious chemical contamination are to

be reviewed by the SSO in order to determine whether changes are needed in

work procedures The SSO will file a complete incident report with the Office

Health and Safety Representative and the Project Coordinator as soon as possible

Radiation

Background for ionizing radiation is normally 001 to 005 mRhr

Background levels at the site that exceed these values should be listed under

background information If levels exceed background but are less than 1 mRhr

the investigation may continue with caution If levels exceed 1 mRhr all

activities must stop and personnel must evacuate the Site or portions of the Site

that exceed 1 mRhr

113 BACKGROUND INFORMATION

Overall Risk is High Moderate _

Low Unknown

1131 FACILITY DESCRIPTION

The Site is located in Acton and Concord Massachusetts on Independence Road

The Grace property is bordered by residential property on the northwest east and west

and industrial properties to the south and northeast Fort Pond Brook bounds the Grace

property to the northwest and the Assabet River bounds the Grace property to the

southeast The Assabet well field which supplies water for the Town of Acton is located

southwest of the Grace property Two inactive sand and gravel pits Massachusetts

Broken Stone Pit and Assabet Sand and Gravel are located south of the Grace property

Former occupants of the Site include American Cyanamid Company which

manufactured explosives and Dewey amp Almy Chemical Company Dewey amp Almy

acquired the property in 1946 and manufactured synthetic rubber container sealant

products An organic chemical plant which produced latex products plasticizers and

resins commenced operation in 1949 A paper battery separator production facility was

constructed in 1951

Grace acquired Dewey and Almy in 1954 and chemical operations were

continued at the Site Grace produced materials used to make concrete and organic

chemicals container sealing compounds latex products and paper and plastic battery

separators Wastewater and solid industrial wastes from these operations were disposed

in several on-site lagoons and an on-site landfill In addition the by-products of some

chemical processes were disposed of in the Slowdown Pit located in the central portion of

the property (Figure 1-2) Discharge to these areas ceased in 1980 Production of organic

chemicals was discontinued in 1982 A small distribution center for concrete additives

(Grace Construction Products) was moved to another location in September 1996 A

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINAL PHASE I RI022S1600 WPD APPD1-11 HSI GeOTianS lllC

second battery separator plant (Daramic) was constructed in 1979 and operations there

continued until 1991 The Daramic facility has not been considered part of the Site All

buildings with the exception of the building associated with the ARS have been

demolished

In 1978 groundwater contamination consisting mainly of 11-dichloroethene

(VDC) and lesser amounts of vinyl chloride ethylbenzene and benzene was detected in

two Acton municipal supply wells Assabet 1 and Assabet 2 located southwest of the

Grace property This discovery prompted a series of investigations which culminated in

the installation of the ARS beginning in late 1983 The ARS is a network of eleven

extraction wells designed to contain and cleanup contaminated groundwater and it is

currently operational

Following installation of the ARS extensive investigations were done by Grace

on in beneath and immediately surrounding the source areas to determine the nature and

extent of contamination by waste disposal practices Following a complete engineering

analysis of cleanup and remedial alternatives for the sources referred to as Operable

Unit-1 (OU-1) a remedy was selected for OU-1 Implementation of the remedy began in

November 1994 and was completed in July 1997 Following completion of the OU-1

remedy a comprehensive review of the groundwater quality and groundwater flow

conditions observed at the Site since the early 1980s and an evaluation of the

effectiveness of the ARS to contain and remediate groundwater affected by the Site was

done in the Initial Site Characterization Report (ISCR) (HSI GeoTrans 1998) While

data reviewed in the ISCR indicated that most areas of the Site containing groundwater

contamination are within the ARS capture zone and that contaminant concentrations in

most wells located outside of the capture zone have decreased significantly since 1984

uncertainties remain regarding the flow of groundwater and the distribution of

contaminants in certain areas of the Site The RIFS is designed to evaluate the extent of

FOR WR GRACE amp Co - CONN M wp_DocsN0992ooofiNALpnASEiRno225i6oowpo APPD1-12 HSI GeoTrans inc

groundwater contamination on- and off-Site and to determine whether additional remedial

measures are necessary to ensure accelerated restoration of the groundwater affected by

the Site to a fully usable condition

The Site property is now inactive as a manufacturing center The perimeter is

identified but due to the size is not secured Access to the Site is controlled through

locked gated entrances and exits The surrounding area is heavily wooded and restricts

the entrance of vehicles to the Site

1132 EXISTING CHEMICAL DATA

The existing historical chemical data for the Site has been compiled through a

thorough review of past activities at the Site and a review of the Site electronic database

For the purposes of this HSP only data collected after the completion of the source

removal activities will be used to evaluate health and safety concerns at the Site The

electronic database was queried in March of 1999 to determine the maximum

concentration and frequency of compounds detected in groundwater at the Site since

January 1 1996 (Table 1-1)

The volatile organic compounds (VOCs) with the highest frequency of detections

and maximum detection shown in parentheses at the Site are benzene (8600 ugL)

VDC (1000 ugL) and vinyl chloride (280 ugL) The semi-volatile organic compounds

(SVOCs) with the highest frequency of detections and maximum detection shown in

parenthesis at the Site are diethlyphthalate (110 ugL) bis(2-ethylhexyl)phthalate (120

ugL) and bis(2- chloroethyl)ether (41 ugL) The inorganic compounds with the highest

frequency of detections and maximum detection shown in parenthesis at the Site are

arsenic (13000 ugL) aluminum (42000 yUgL) nickel (890 ugL) and cadmium (16

ugL) The groundwater data collected indicate that pesticides and PCBs are not a

concern at the Site (HSI GeoTrans 1998) Therefore no pesticides or PCBs will be

Other compounds have been detected at varying concentrations and at a wide

range of frequencies at the Site Because such a wide range of VOCs SVOCs and

inorganics have been detected at the Site it was necessary to screen these compounds for

potential health hazards and exposure risks A full discussion of the potential health

hazard and exposure risk screening is provided in Attachment A Attachment A also

includes tables which indicate the physical description and associated health hazards for

each compound detected at the Site (Attachment A Table A-l) the exposure limits and

monitoring properties for each compound detected at the Site (Attachment A Table A-2)

compounds with gas and vapor exposure limits less than 5 ppm (Attachment A Table Ashy

3) compounds with particulate exposure limits less than 1 mgm3 (Attachment A Table

A-4) and a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) (Attachment A Table A-5)

Based on the screening discussed in Attachment A it was determined that the

compounds listed in Table 1-2 are contaminants of monitoring concern These

compounds have vapor exposure limits less than 5 ppm have been detected at least four

times and have a maximum detection concentration greater than 10 ppb (ugL) The

compounds found at the highest frequency and with greatest maximum concentration at

the Site benzene VDC and vinyl chloride are included in the list of compounds of

monitoring concern and comprise the lowest exposure limits Therefore benzene VDC

and vinyl chloride will be used as indicator compounds for vapor monitoring during work

tasks No dust monitoring will be conducted Work practices and investigation derived

waste (IDW) management practices will be used that will minimize the potential for

contaminated soil to be suspended in breathing space air Because vapor monitoring

action levels are lower than LEL action levels (10 percent of the LEL) no LEL

monitoring is required aside from that associated with confined space entry of the

recovery well vaults

POTENTIAL HEALTH HAZARD AND EXPOSURE RISK SCREENING

FOR WR GRACE amp Co - CONN M wp_Docswo992oooFiNALpiiASE i wo225 i6oo wro ATTA1-1 HSI GeoTrans inc

POTENTIAL HEALTH HAZARD AND EXPOSURE RISK SCREENING

The historical chemical data for the Site has been compiled through a thorough

review of past activities at the Site and a review of the Site electronic database For the

purposes of this HSP only data collected after the completion of the source removal

activities will be used to evaluate health and safety concerns at the Site The electronic

database was queried in March of 1999 to determine the maximum concentration and

frequency of compounds detected in groundwater at the Site since January 1 1996 (see

Table 1-1)

A hazard screening evaluation was performed for each compound identified in the

database search described above Table A-l indicates the associated health hazards

(exposure routes symptoms and target organs) for compounds detected at the Site and

the physical description (eg color solidliquidgas phase odor) Compounds for which

the NIOSH guide (NIOSH 1998) did not contain health hazard or physical description

information are shown with no information in the table row Some physical descriptions

for compounds were gathered from other sources (See Table A-l citation notes)

Table A-2 provides the exposure limits a summary of daily time weighted

average (Per Day TWA) and the 15 minute short term (15 min STEL) ceiling and

immediately dangerous to life or health (IDLH) exposure limits The limits shown are the

most stringent quantified exposure limits put forth by OSHA NIOSH and ACGIH for

each exposure limit category

Compounds that NIOSH considers to be potential occupational carcinogens are

designated with a check in the CA box in Tables A-2 A-3 and A-4 NIOSH usually

recommends that occupational exposures to carcinogens be limited to the lowest feasible

concentration (LFC) Those compounds NIOSH has identified as potential carcinogens

but has not quantified recommended exposure limits (REL) are designated with LFC

under the Most Stringent Exposure Limit column in Attachment A Table A-3 The

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FINA1 PHASE I RT02251600 WPD ATT A1 -2 HSI GeOTiaHS lllC

ACGIH has categorized compounds into five carcinogenicity groups based on available

information Al for confirmed human carcinogens A2 for suspected human carcinogens

A3 for confirmed animal carcinogen with unknown relevance to humans A4 for not

classifiable as a human carcinogen and A5 for compounds not suspected as a human

carcinogen The carcinogenicity category for compounds which ACGIH has designated

is also shown in Tables A-2 A-3 and A-4

The compounds that have potential air monitoring concerns for this Site are those

compounds designated in Table A-3 with LFC an ACGIH carcinogenicity of Al or A2

a gas and vapor exposure limit of 5 ppm or less or with a suspended-in-air particulate

exposure limit of 1 mgm3 or less Tables A-3 and A-4 summarize the most stringent gas

and vapor and particulate exposure limits for these compounds respectively

The compounds with gas and vapor exposure limits of 5 ppm or less which were

detected at low frequency and low concentration (three or fewer times and at a

concentration less than 10 ppb (^gL)) are not considered to be of monitoring concern

(Table A-3) The remaining compounds in Table A-3 have only been detected at

locations where the concentration of benzene VDC and vinyl chloride represent the

majority of the total concentration of chemicals with monitoring concerns Because the

exposure limits for benzene VDC and vinyl chloride are low and these compounds make

up the majority of contamination in groundwater at the Site monitoring for benzene

VDC and vinyl chloride is a conservative means to evaluate work task exposure risks

which establish action level PPE modifications In order to screen for the compounds in

Table A-3 detector tubes or other compound specific monitoring devices for the indicator

parameters (benzene VDC and vinyl chloride) will be used according to action levels

associated with the tasks to be performed

The compounds with a suspended-in-air particulate exposure limit of 1 mgm3 or

less which were detected at low frequency and low concentration (three or fewer times

and at a concentration less than 10 ppb (^gL)) are not considered to be of monitoring

FOR WR GRACE amp Co - CONN M WP_DOCSN0992000FlNALPHAbElRI02251600 WO ATTA1-3 HSI GCOTfanS 1HC

concern (Table A-4) Work practices and investigation derived waste (1DW)

management practices will be used that will minimize the potential for contaminated soil

to be suspended in breathing space air above the exposure levels for the remaining

compounds

Table A-5 is a listing of compounds with explosive limits (LELsUELs) and their

corresponding action levels (10 percent of the LEL) Because vapor monitoring action

levels are lower than LEL action levels (10 percent of the LEL) no LEL monitoring is

required

Personnel including unauthorized personnel that suffer chemical overexposure shall

be treated in the following manner

bull Skin Contact Remove contaminated clothing Wash immediately with water Use soap if available

bull Inhalation Remove from contaminated atmosphere Artificial respiration is necessary Transport to hospital

bull Ingestion Never induce vomiting on an unconscious person Also never induce vomiting when acids alkalis or petroleum products are suspected Contact the poison control center

bull Ionizing Radiation Normal background 001 to 005 mRhr If less than 1 mRhr continue investigation with caution If greater than 1 mRhr evacuate site

These personnel shall be observed by the Site Safety Officer to ascertain whether

there are any symptoms resulting from overexposure If there is any visible manifestation

of overexposure such as skin irritation Project Personnel should be examined by a

physician All episodes of obvious chemical contamination are to be reviewed by the Site

Cold Stress

Persons working outdoors in temperatures at or below freezing may be frostbitten

Exposure to extreme cold for a short time may cause severe injury to the surface of the

body or result in profound generalized cooling causing death Areas of the body that

have a high surface-area-to-volume ratio such as fingers toes and ears are the most

susceptible Two factors influence the development of a cold injury ambient temperature

and the velocity of the wind Wind chill is used to describe the chilling effect of moving

air in combination with low temperature For instance 10degF with a wind of 15 mph is

equivalent in chilling effect to still air at -18degF

As a general rule the greatest incremental increase in wind chill occurs when a wind

of 5 mph increases to 10 mph Additionally water conducts heat 240 times faster than

air Thus the body cools suddenly when chemical-protective equipment is removed if the

clothing underneath is soaked with perspiration Local injury resulting from cold is

included in the generic term frostbite There are several degrees of damage

Systemic hypothermia is caused by exposure to freezing or rapidly dropping

temperature Its symptoms are usually exhibited in five stages (1) shivering (2) apathy

listlessness sleepiness and (sometimes) rapid cooling of the body to less than 95 degF (3)

unconsciousness glassy stare slow pulse and slow respiratory rate (4) freezing of the

extremities and finally (5) death

Prevention of Cold Stress can be achieved by (1) Modification of work schedules as

required by site conditions and personnel monitoring (2) Provision of shelters to protect

workers during rest periods (3) Maintenance of body heat at normal levels by wearing

adequate layers of clothing (4) Training site personnel to recognize and treat cold stress

(5) Frequent warm up breaks (6) Acclimation

Heat Stress

Wearing personal protective equipment puts a field worker at considerable risk of

developing heat stress This can result in health effects ranging from transient heat

fatigue to serious illness or death Heat stress is an aggregate of all the heat factors both

internal and external that work on the body

FOR WR GRACE amp Co - CONN MWP_DOCSNON2000F[NALP11ASEIRI0225600WPO ATT B1-18 HSI GCOTfanS IHC

External factors that contribute to heat stress include ambient air temperature

radiant temperature air velocity and the relative humidity Internal factors include

metabolic heat body core temperature respiration rate and acclimation

Early symptoms of heat stress include mental confusion and the inability to

concentrate heat rash and heat cramps (muscle spasms andor pain in hands feet and

abdomen) Acute and chronic heat stress impacts a workers temperament causing

impulsive aggressive and violent acts to be committed by the victim Signs of heat

exhaustion include pale cool moist skin heavy sweating dizziness nausea and fainting

Heat stroke is the most serious form of heat stress Immediate action must be taken to

cool the body and prevent serious injury Competent medical help must be obtained

Signs include red hot dry skin lack of or reduced perspiration nausea dizziness and

confusion strong rapid pulse and coma The case-fatality of heat-stroke and heat

exhaustion is probably no lower than 10 percent Because heat stress is one of the most

common (and potentially serious) illnesses at field sites regular monitoring and other

preventative precautions are vital

To monitor for heat stress measure

(1) Heart rate mdash Count the radial pulse during a 30-second period as early as possible during rest periods If the heart exceeds 110 beats per minute at the beginning of the rest period shorten the next work cycle by one-third and keep the rest period the same If the heart rate still exceeds 110 beats per minute at the next rest period shorten the following work cycle by one-third again

(2) Oral temperatures mdash Use an oral thermometer to measure the oral temperature at the end of the work period (before drinking) If oral temperature exceeds 996 degrees F shorten the next work cycle by one-third without changing the rest period Repeat if necessary Do not permit a worker to wear PPE when the workers oral temperature is above 1006 degrees F

(3) Body weight mdash If possible measure weight at the beginning and end of each day to see if enough fluids are being taken during the day The body water loss should not exceed 15 percent of total body weight in a work day

Prevention of heat stress can be achieved by

(1) Modification of work schedules as required by site conditions and personnel monitoring

(2) Provision of shelters or shaded areas to protect workers during rest periods

(3) Maintenance of body fluids at normal levels by drinking cold water and

(4) Training Site Personnel to recognize and treat heat stress signs

(5) Acclimation

Terra Tech Inc Safe Work Practices Issue Date July 1998 Non-Permit-Required Confined Space Entry Practices Revision No 1 SWPNo 6-24 Page 1

NON-PERMIT-REQUIRED CONFINED SPACE ENTRY PRACTICES

The following safe work practices (SWP) apply to entry into confined spaces classified as non-permitshy

required The confined space must conform to the definition of a non-permit-required confined space as

discussed in the Confined Space Entry Program (see Document Control No 2-5 in Volume I) Entry into

spaces classified as non-permit-required are preferable over entry into permit-required spaces When

feasible efforts shall be directed to prepare confined spaces so they meet the definitions of non-permitshy

required confined space

If any of the procedures discussed in this SWP cannot be completed or an unanticipated hazard is

identified the non-permit-required status of the space will be revoked until the space is re-evaluated and

reapproved as a non-permit-required space by a technically qualified individual such as a Tetra Tech

health and safety specialist

Non-permit-required confined space entry procedures before entry into the space are listed below

bull The project manager and the site safety coordinator (SSC) should be notified of the need to enter into a confined space This notification must allow sufficient time to assemble necessary safety equipment

bull A blank Preparation and Testing of Non-Permit Required Confined Space form (Form CS-2) must be obtained (see Volume HI)

bull The necessary safety equipment can include but is not limited to atmospheric testing meters and devices a mechanical ventilator and a ladder for entry and exit

bull All equipment to be used during entry must be tested and inspected before use Atmospheric testing equipment shall be calibrated in accordance with the manufacturers instructions to ensure proper operation Calibration parameters shall be documented in the field logbook and the equipment will be tagged with a label specifying these parameters

bull Hazardous conditions associated with the removal of the entrance cover should be eliminated before opening the confined space After removal of the entrance cover the opening should be promptly barricaded by a railing temporary cover or other temporary barrier to prevent employees and equipment from accidentally falling through the opening

bull The internal atmosphere should be tested for the following conditions in the order given

- Oxygen content (should be between 195 to 235 percent)

- Combustible gases (should be less than 10 percent of the lower explosive limit)

- Potential toxic air contaminants

bull The space should be tested at all levels (top middle and bottom) and in all areas where work may occur The atmosphere within the space must not be hazardous whenever an employee is inside the space

bull If forced-air ventilation is used the following conditions apply

mdash Ventilation should not be used to control continuous sources of hazardous contaminants

- There must be a clean source of air that will not increase the hazard within the space

bull The entrant shall document on Form CS-2 that the space is safe for entry and that preshyentry measures required by this SWP have been taken The form shall be made available to each employee entering the space and shall be kept at the work site until completion of confined space work The certificate will then become part of the permanent project file

The atmosphere within the confined space must be tested periodically while entrants are within the

confined space Frequency of testing shall be every 30 minutes during the first 2 hours then hourly

afterwards when entrants are in the confined space If at any time during occupancy a hazardous

atmosphere is detected the entrants shall leave the space immediately The space shall then be evaluated

to determine how the hazardous atmosphere developed and measures shall be implemented to protect

employees from the hazardous atmosphere before any subsequent entry Re-entry shall not be allowed

until atmospheric testing demonstrates acceptable conditions

When changes in the use or configuration of a non-permit-required space cannot be eliminated or

controlled the SSC shall re-evaluate the space and if necessary reclassify it as a permit-required

confined space

Health Rating 3 - Severe (Poison) Flammability Rating 0 - None Reactivity Rating 2 - Moderate Contact Rating 3 - Severe (Corrosive) Lab Protective Equip GOGGLES amp SHIELD LAB COAT amp APRON VENT HOOD PROPER GLOVES Storage Color Code White (Corrosive)

Potential Health Effects

Inhalation Corrosive Inhalation of vapors can cause coughing choking inflammation of the nose throat and upper respiratory tract and in severe cases pulmonary edema circulatory failure and death Ingestion Corrosive Swallowing hydrochloric acid can cause immediate pain and bums of the mouth throat esophagus and gastrointestinal tract May cause nausea vomiting and diarrhea Swallowing may be fatal Skin Contact Corrosive Can cause redness pain and severe skin burns Concentrated solutions cause deep ulcers and discolor skin Eye Contact Corrosive Vapors are irritating and may cause damage to the eyes Contact may cause severe burns and permanent eye damage Chronic Exposure Long-term exposure to concentrated vapors may cause erosion of teeth Long term exposures seldom occur due to the corrosive properties of the acid Aggravation of Pre-existing Conditions Persons with pre-existing skin disorders or eye disease may be more susceptible to the effects of this substance

4 First Aid Measures

Inhalation Remove to fresh air If not breathing give artificial respiration If breathing is difficult give oxygen Get medical attention immediately Ingestion DO NOT INDUCE VOMITING Give large quantities of water or milk if available Never give anything by mouth to an unconscious person Get medical attention immediately Skin Contact hi case of contact immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes Wash clothing before reuse Thoroughly clean shoes before reuse Get medical attention immediately

HYDROCHLORIC ACID 33 - 40 httpwwwjtbakercommsdsh3880htm

Eye Contact Immediately flush eyes with plenty of water for at least 15 minutes lifting lower and upper eyelids occasionally Get medical attention immediately

5 Fire Fighting Measures

Fire Extreme heat or contact with metals can release flammable hydrogen gas Explosion Not considered to be an explosion hazard Fire Extinguishing Media If involved in a fire use water spray Neutralize with soda ash or slaked lime Special Information In the event of a fire wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode Structural firefighters protective clothing is ineffective for fires involving hydrochloric acid Stay away from ends of tanks Cool tanks with water spray until well after fire is out

6 Accidental Release Measures

Ventilate area of leak or spill Wear appropriate personal protective equipment as specified in Section 8 Isolate hazard area Keep unnecessary and unprotected personnel from entering Contain and recover liquid when possible Neutralize with alkaline material (soda ash lime) then absorb with an inert material (e g vermiculite dry sand earth) and place in a chemical waste container Do not use combustible materials such as saw dust Do not flush to sewer US Regulations (CERCLA) require reporting spills and releases to soil water and air in excess of reportable quantities The toll free number for the US Coast Guard National Response Center is (800) 424-8802

J T Baker NEUTRASORB(tm) or TEAM(tm) Low Na+ acid neutralizers are recommended for spills of this product

7 Handling and Storage

Store in a cool dry ventilated storage area with acid resistant floors and good drainage Protect from physical damage Keep out of direct sunlight and away from heat water and incompatible materials Do not wash out container and use it for other purposes When diluting the acid should always be added slowly to water and in small amounts Never use hot water and never add water to the acid Water added to acid can cause uncontrolled boiling and splashing When opening metal containers use non-sparking tools because of the possibility of

mdash- hydrogen gas being present Containers of this material may be hazardous when empty since they retain product residues (vapors liquid) observe all warnings and precautions listed for the product

8 Exposure ControlsPersonal Protection

Airborne Exposure Limits -OSHA Permissible Exposure Limit (PEL) 5 ppm Ceiling -ACGIH Threshold Limit Value (TLV) 5 ppm Ceiling

Ventilation System A system of local andor general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source preventing dispersion of it into the general work area Please refer to the ACGIH document Industrial Ventilation A Manual of Recommended Practices most recent edition for details Personal Respirators (NIOSH Approved) If the exposure limit is exceeded a full facepiece respirator with an acid gas cartridge may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier whichever is lowest For emergencies or instances where the exposure levels are not known use a full-facepiece positive-pressure air-supplied respirator WARNING Air purifying respirators do not protect workers in oxygen-deficient atmospheres Skin Protection Rubber or neoprene gloves and additional protection including impervious boots apron or coveralls as needed in areas of unusual exposure to prevent skin contact Eye Protection Use chemical safety goggles andor a full face shield where splashing is possible Maintain eye wash fountain and quick-drench facilities in work area

Menzie-Cura amp Associates Addendum to the HIS Geotrans Health and Safety Plan WR Grace Superfund Site

Acton Massachusetts

Menzie-Cura amp Associates Inc adopts the HSI Geotrans Health and Safety Plan (HSP) The HSP contains a hazard assessment for contaminants found at the Site historically In addition to HSI Geotrans HSP Menzie-Cura amp Associates Inc personnel will following the boating safety procedures identified here when sampling in Sinking Pond and the reference pond

This work will take place in a small boat (possibly using a gasoline run outboard motor) All personnel will wear a United States Coast Guard approved personal flotation device (PFD) whenever working from the boat No smoking is allowed at any time in the boat or within 50 feet of it during refueling The Captain will be named at a later date At the Captains discretion he or she can modify or cancel any on-board operation for safety reasons Such reasons may include but are not limited to weather condition of boat or motor condition of sampling equipment or preparedness of personnel All personnel working on board will follow his or her orders

We will follow small boat safety procedures The boats transom or seats will contain a plate which describes the total weight capacity and other limitations of the particular boat used We will not exceed these The boats equipment will include motor full spare gasoline tank oars installed oar locks Danforth anchor 50 feet of half inch nylon anchor line terminated in three feet of half inch galvanized chain a metered and weighted line to estimate depth personal flotation devices (PFDs) for everyone on board a two quart canteen of drinking water (otherwise there should be no food on-board) and a cell phone

Personnel on board will each carry a belted and sheathed jack knife or rigging knife On-board personnel will be aware of the position of their bodies relative to coiled or faired lines or lines under tension Especially do not put hands or feet in any basket containing a faired line or sit upon a coiled deck line Always position yourself to one side of a line under tension Never position yourself behind a line under tension or between such a line and the gunnel of the boat or any other immovable object During over the side operations lower all lines Never let a weighted line free fall The most common way to drown is to go over the side with a free falling anchor or equipment line tangled around a leg arm or neck Grab samplers are not intended to free fall they are designed to be lowered It may be necessary to let certain samplers free fall a short distance (ie several feet) from above the bottom Lower them to that height above bottom Always know the depth to bottom before deploying equipment

Generally stay seated in the boat It is sometimes necessary to stand when deploying equipment Do this keeping your center of gravity as low as possible and as near the center line of the boat as possible Before standing or changing your position in the boat announce your intentions to all on-board
