ITEM 24 GROUND WATER MANAGEMENT AREAS

PLANT SITE 3 (GMA 4) (GECD340)

DECEMBER 2003

All activities described below for this item were conducted pursuant to the Consent Decree

a Activities UndertakenCompleted

Completed semi-annual groundwater sampling and analysis including re-collection of sample from OPCA-MW-4 for analysis of dioxinsfurans (original sample damaged at laboratory)

b SamplingTest Results Received

See attached tables

Preliminary analytical results received in December 2003 from the fall 2003 GMA 4 interim groundwater quality monitoring activities are shown in Table 24-2 These preliminary results have been compared to the Method 1 GW-2 and GW-3 groundwater standards and UCLs for groundwater set forth in the MCP In these comparisons for PCBs and inorganics the filtered sample results were used for the comparisons to the Method 1 GW-3 standards (there are no GW-2 standards for these constituents) and the unfiltered sample results were used for the comparisons to UCLs These comparisons indicate the following

bull There were no exceedances of UCLs in any of the groundwater sample results received in December 2003

bull The MCP GW-2 standards were not exceeded in any of the GW-2 groundwater sample results received in December 2003

bull The MCP GW-3 standard for PCBs (00003 ppm) was slightly exceeded in the filtered sample from monitoring well OPCA-MW-8 This is the first such exceedance observed in this well No other MCP GW-3 standards were exceeded in any of the groundwater sample results received in December 2003

10 Introduction

11 Background

In 1972 amendments were made to the Clean Water Act (CWA) prohibiting the discharge of any pollutant from a point source to waters of the United States unless the discharge is authorized by a National Pollutant Discharge Elimination System (NPDES) permit Since the passing of the 1972 amendments to the CWA significant progress has been made in cleaning up industrial process wastewater and municipal sewage

The purpose of the National Pollutant Discharge Elimination System (NPDES) Program is to protect human health and the environment The Clean Water Act requires that all point sources discharging pollutants into waters of the United States must obtain an NPDES permit By point sources EPA means discrete conveyances such as pipes or man made ditches

For many years discharge limits were based on available technology for wastewater treatment However in 1984 the US Environmental Protection Agency (EPA) released a national policy statement entitled Policy for the Development of Water Quality-Based Permit Limitations for Toxic Pollutants (US EPA 1984) which addresses the control of toxic pollutants beyond technology-based requirements in order to meet water quality standards To implement the new policy guidance was provided to the respective state and regional permit personnel in the EPAs Technical Support Document for Water Quality-Based Toxics Control (US EPA 1985 US EPA 1991) The EPAs

policy statement and the support document recommended that where appropriate permit limits should be based on effluent toxicity as measured in aquatic toxicity tests

12 Clean Water Act 33 USC ss 1251 et seq (1977)

The Clean Water Act is a 1977 amendment to the Federal Water Pollution Control Act of 1972 which set the basic structure for regulating discharges of pollutants to waters of the United States The law gave EPA the authority to set effluent standards on an industry basis (technology-based) and continued the requirements to set water quality standards for all contaminants in surface waters The CWA makes it unlawful for any person to discharge any pollutant from a point source into navigable waters unless a permit (NPDES) is obtained under the Act The 1977 amendments focused on toxic pollutants In 1987 the CWA was reauthorized and again focused on toxic substances authorized citizen suit provisions and funded sewage treatment plants (POTWs) under the Construction Grants Program The CWA provisions for the delegation by EPA of many permitting administrative and enforcement aspects of the law to state governments In states with the authority to implement CWA programs EPA still retains oversight responsibilities

13 Objective of the General Electric Study The objective of this study was to measure the acute toxicity of the composite wastewater discharged by the General Electric facility located in Pittsfield Massachusetts using Daphnia pufex under static conditions Whereas D pulex are not considered locally important they are routinely used by regulatory agencies and contract laboratories nationwide for toxicity testing A toxicity test was conducted from December 3 2003 to December 5 2003 at SGS Environmental Services Charleston West Virginia All original raw data and the final report produced for this study are stored in SGSs archives at the above location

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 11 SGS

25 Test Organisms

Daphnids (Daphnia pulex) less than 24-hours old were obtained from SGS

laboratory cultures maintained in Charleston The culture system consisted of twenty-four (24) 100 ml disposable plastic beakers each containing 80 ml of culture medium and one (1) daphnid The culture medium was deionized (DI) water for which the hardness was raised by addition of reagent grade chemicals (US EPA 1993) Prior to use the culture water was characterized

Parameter Result Total Hardness within range of 80-110 mgL Alkalinity (as CaCO3) within range of 60-70 mgL pH within range of 70 to 72

The culture area was maintained at a temperature of 20degC (plusmn 1degC) with a

regulated photoperiod of 16 hours of light and 8 hours of darkness

Daphnid cultures were fed a combination of green algae (Setanastrum

capricorium] approximately 40 x 107 cellsml) and YCT (yeast cereal leaves and trout chow) Approximately 10 ml of algae and 05 ml of YCT was added to each culture vessel daily Three times per week daphnids are transferred to fresh culture media

Approximately twenty-four hours before test initiation all immature daphnids were removed from the culture flasks Offspring produced during the period were used in the toxicity test

26 Test Procedures

A subsample of the effluent and the dilution water (approximately 2250 ml) was analyzed by SGS for total phosphorus chloride total suspended solids and total solids The 48-hour toxicity test was conducted at concentrations of 100 75 50 35 15 and 5 effluent Test concentrations were prepared by diluting

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 12 SGS

the appropriate volume of effluent with dilution water to a total volume of 250 ml Test solutions were then divided into replicate (5 replicates per concentration) 30 ml medicine cups each containing 20 ml of test solution One set of five control beakers (containing Housatonic River water) and one set of five reference control beakers (containing moderately hard reconstituted water) were established and maintained under the same conditions as the exposure concentrations A secondary set of five reference control beakers (containing sodium thiosulfate) was also maintained Test solutions were placed in an incubator to maintain solution temperature of 20degC (plusmn 1degC) Light was provided on a 16-hour light and 8-hour dark photoperiod Florescent bulbs provided an illumination of 90 to 100 foot-candles in the test area

Prior to test initiation daphnids less than 24-hours old were culled individually with a plastic pipette and placed into a 1000 ml holding beaker containing approximately 500 ml of reference water The test was initiated when daphnids were individually transferred from the holding beaker to the test solutions (4 daphnids per replicate) The daphnids were fed prior to test initiation but were not fed during the exposure period

27 Test Monitoring

The number of mortalities and observations in each replicate vessel were recorded at 24 and 48 hours of exposure and observed mortalities were removed from the test solutions Biological observations and observations from the physical characteristics of each replicate test solution and control were also made and recorded at 0 24 and 48 hours Dissolved oxygen concentrations pH and temperature were measured at test initiation and at 24-hour intervals thereafter in one replicate vessel (a) for each test concentration in which there were surviving organisms

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 13 SGS

Total hardness concentrations were measured by the EDTA titrimetric method and total alkalinity concentrations were determined by potentiometric titration to an endpoint of pH 45 (APHA 1989) Total residual chorine was measured by Hach test Concentrations of ammonia were determined using a Buchi model 212 distillation unit and titrated automatically with a Brinkman titroprocessor Specific conductivity was measured with a Cole Palmer Model 71250 salinityshyconductivity-temperature meter and probe pH was measured with a Fisher Scientific Accumet 910 pH meter and combination electrode dissolved oxygen concentration was measured with an YSI Model 59 dissolved oxygen meter Daily temperature measurements were performed with a Princo mercury thermometer and a Fisher minimum-maximum thermometer Light intensity was measured with a General Electric type 217 light meter

28 Reference Toxicity Test

A 48-hour reference toxicity test exposing Daphnia pulex to sodium chloride (NaCI) was conducted from December 2 2003 to December 4 2003 The reference test was conducted to establish the health of the test organisms The reference toxicity test included five NaCI concentrations and a dilution water control (moderately hard reconstituted water) The nominal NaCI concentrations for the test with Daphnia pulex ranged from 625 to 10000 mg of NaCIL Test methods were the same as those described above for the effluent test

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 14 SGS

30 Statistics

The concentration-response relationships observed were characterized by the median lethal concentrations (LC50) which is the concentration that is calculated to be lethal to 50 percent of the organisms within the test period If no concentration caused mortality of 50 then the LC50 value was determined to be greater than the highest concentration tested and no statistical analysis were performed If at least one concentration caused mortality of greater than 50 of the test population then a computer program (TOXSTAT 35) was used to calculate the LC50 value Three statistical methods were available in the computer program probit analysis the Trimmed Spearman-Karber and the Spearman-Karber methods The graphical method is available if appropriate Generally to choose the best estimate of the LC50 value for a particular data set the US EPA flow chart on page 15 was followed

The No-Observable-Acute-Effect-Level (NOAEL) was estimated for the acute toxicity test and is defined as the highest concentration of effluent that produced gt 90 survival

10 Summary

This document describes the procedure for the culture of Ceriodaphnia dubia Daphnia pulex Daphnia magna that are used in aquatic toxicity testing

20 Mass Stock Cultures of Ceriodaphnia dubia Daphnia pulex and Daphnia magna

21 Stock cultures are maintained in 1000 ml beakersjars with 900 mis of culture media at 20 plusmn 1deg C These cultures are maintained only as a back-up source of organisms

22 Culture media for Ceriodaphnia dubia and Daphnia pulex is moderately-hard synthetic water Culture media for Daphnia magna is hard synthetic water (see document control number 700504 Culture Waters for Aquatic Toxicity Testing)

23 Many cultures are maintained simultaneously with an informal rotation cycle New cultures are started with young produced by individual cultures These cultures are maintained for approximately 3 weeks after which they are discarded

24 Cultures are fed YCT (yeast cerophyll digested trout chowflake food) and algae (Selanastrum capricorium) on Monday Wednesday and Friday Feeding as well as culture rotation temperature and all other relevant data is recorded by species in a log book

25 Stock cultures are also fed algae and YCT These feedings are recorded in the log book

30 Individual Cultures of Ceriodaphnia dubia Daphnia pulex Daphnia magna

31 Cultures of Daphnia magna and Daphnia pulex are maintained in 100 ml plastic beakers Twenty-four (24) beakers with one organism each are kept at all times to ensure continuous availability of neonates for testing Cultures of individual Ceriodaphnia dubia are maintained in 30 ml sterile plastic medicine cups One to two cultures of approximately 100 organisms each are kept at all times

Document Control Number 7006 Page 2 of 3______________________________________________

32 Cultures are renewed three times per week Organisms are fed daily

40 Obtaining Neonates for Testing

41 Cultures of Ceriodaphnia are started by placing one neonate into a 30 ml disposable plastic cup containing approximately 20 ml of Moderately Hard Synthetic Water New Ceriodaphnia cultures are started every ten to fourteen days D magna and D putex are replaced whenever mortality occurs

42 The individual cultures are transferred to fresh media three times per week Synthetic water algae and YCT are mixed prior to pouring into culture vessel to ensure uniformity of media The old media and neonates are kept for stock cultures for several weeks and then discarded

43 To assure neonates for chronic tests are of a very similar age transfer of individual brood stock to fresh media should be made the morning of the test The cultures are then checked approximately every two hours to find an adequate number of neonates all released with an 8 hour period For acute tests individuals are either transferred less than 24 hours before a test or the young are separated from adults less than 24 hours before a test

44 Young used in chronic testing are obtained from adults who have produced at least three broods with no less than 8 neonates in their third or subsequent brood Neonates are then distributed in a blocking procedure ie neonates from the same organism are placed in one replication of each concentration

50 DAPHNIA Food

51 Digested Flake Food

511 Add 5g flake food to 1 L deionized water Mix well in a blender and place in a 2 L separatory funnel To digest aerate this mixture at room temperature for one week

To insure that healthy organisms are used in testing CTampE performs monthly QAQC tests on all in-house cultured organisms CTampE uses Sodium Chloride as a reference toxicant

20 Plmephales promelas

21 48 hour static acute toxicity tests are run at 20degC (plusmn1degC) using fish 1 to 14 days old

22 This test consists of a control and a dilution series of 10gL 9gL 8gL 7gL and 6gL of sodium chloride Other dilution series may be used

23 The dilutions are prepared in 800 ml disposable plastic beakers using moderately hard synthetic water 500 mis of test solution is placed in each of two replications Water quality values are measured and recorded at this time

24 Ten organisms are placed in each replicate Fish are loaded by first siphoning them into a shallow pan from which they are transferred to the beakers with a large bore pipette

25 The test is terminated at 48 hours At this time mortalities are recorded along with final water quality data

30 Daphnids (Ceriodaphnia dubia Daphnia magna Daphnia pulex)

31 48 hour static acute tests are performed at 25degC (plusmn1degC) using organisms less than 24 hours old

32 These tests consist of a control and a five dilution series The concentration of the reference toxicant is varied depending on species

10 Introduction

11 Background

In 1972 amendments were made to the Clean Water Act (CWA) prohibiting the discharge of any pollutant from a point source to waters of the United States unless the discharge is authorized by a National Pollutant Discharge Elimination System (NPDES) permit Since the passing of the 1972 amendments to the CWA significant progress has been made in cleaning up industrial process wastewater and municipal sewage

The purpose of the National Pollutant Discharge Elimination System (NPDES) Program is to protect human health and the environment The Clean Water Act requires that all point sources discharging pollutants into waters of the United States must obtain an NPDES permit By point sources EPA means discrete conveyances such as pipes or man made ditches

For many years discharge limits were based on available technology for wastewater treatment However in 1984 the US Environmental Protection Agency (EPA) released a national policy statement entitled Policy for the Development of Water Quality-Based Permit Limitations for Toxic Pollutants (US EPA 1984) which addresses the control of toxic pollutants beyond technology-based requirements in order to meet water quality standards To implement the new policy guidance was provided to the respective state and regional permit personnel in the EPAs Technical Support Document for Water Quality-Based Toxics Control (US EPA 1985 US EPA 1991) The EPAs

policy statement and the support document recommended that where appropriate permit limits should be based on effluent toxicity as measured in aquatic toxicity tests

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 8SGS

12 Clean Water Act 33 USC ss 1251 et seq (1977)

The Clean Water Act is a 1977 amendment to the Federal Water Pollution Control Act of 1972 which set the basic structure for regulating discharges of pollutants to waters of the United States The law gave EPA the authority to set effluent standards on an industry basis (technology-based) and continued the requirements to set water quality standards for all contaminants in surface waters The CWA makes it unlawful for any person to discharge any pollutant from a point source into navigable waters unless a permit (NPDES) is obtained under the Act The 1977 amendments focused on toxic pollutants In 1987 the CWA was reauthorized and again focused on toxic substances authorized citizen suit provisions and funded sewage treatment plants (POTWs) under the Construction Grants Program The CWA provisions for the delegation by EPA of many permitting administrative and enforcement aspects of the law to state governments In states with the authority to implement CWA programs EPA still retains oversight responsibilities

13 Objective of the General Electric Study The objective of this study was to measure the acute toxicity of the composite wastewater discharged by the General Electric facility located in Pittsfield Massachusetts using Daphnia pufex under static conditions Whereas D pulex are not considered locally important they are routinely used by regulatory agencies and contract laboratories nationwide for toxicity testing A toxicity test was conducted from December 3 2003 to December 5 2003 at SGS Environmental Services Charleston West Virginia All original raw data and the final report produced for this study are stored in SGSs archives at the above location

22 Effluent Sample

The effluent sample (A5288C) was collected by GE personnel from December 1 2003 to December 2 2003 Upon receipt at SGS on December 3 2003 the sample temperature was 34deg C The effluent sample was characterized as having

25 Test Organisms

Daphnids (Daphnia pulex) less than 24-hours old were obtained from SGS

laboratory cultures maintained in Charleston The culture system consisted of twenty-four (24) 100 ml disposable plastic beakers each containing 80 ml of culture medium and one (1) daphnid The culture medium was deionized (DI) water for which the hardness was raised by addition of reagent grade chemicals (US EPA 1993) Prior to use the culture water was characterized

Parameter Result Total Hardness within range of 80-110 mgL Alkalinity (as CaCO3) within range of 60-70 mgL pH within range of 70 to 72

The culture area was maintained at a temperature of 20degC (plusmn 1degC) with a

regulated photoperiod of 16 hours of light and 8 hours of darkness

Daphnid cultures were fed a combination of green algae (Setanastrum

capricorium] approximately 40 x 107 cellsml) and YCT (yeast cereal leaves and trout chow) Approximately 10 ml of algae and 05 ml of YCT was added to each culture vessel daily Three times per week daphnids are transferred to fresh culture media

Approximately twenty-four hours before test initiation all immature daphnids were removed from the culture flasks Offspring produced during the period were used in the toxicity test

26 Test Procedures

A subsample of the effluent and the dilution water (approximately 2250 ml) was analyzed by SGS for total phosphorus chloride total suspended solids and total solids The 48-hour toxicity test was conducted at concentrations of 100 75 50 35 15 and 5 effluent Test concentrations were prepared by diluting

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 12 SGS

the appropriate volume of effluent with dilution water to a total volume of 250 ml Test solutions were then divided into replicate (5 replicates per concentration) 30 ml medicine cups each containing 20 ml of test solution One set of five control beakers (containing Housatonic River water) and one set of five reference control beakers (containing moderately hard reconstituted water) were established and maintained under the same conditions as the exposure concentrations A secondary set of five reference control beakers (containing sodium thiosulfate) was also maintained Test solutions were placed in an incubator to maintain solution temperature of 20degC (plusmn 1degC) Light was provided on a 16-hour light and 8-hour dark photoperiod Florescent bulbs provided an illumination of 90 to 100 foot-candles in the test area

Prior to test initiation daphnids less than 24-hours old were culled individually with a plastic pipette and placed into a 1000 ml holding beaker containing approximately 500 ml of reference water The test was initiated when daphnids were individually transferred from the holding beaker to the test solutions (4 daphnids per replicate) The daphnids were fed prior to test initiation but were not fed during the exposure period

27 Test Monitoring

The number of mortalities and observations in each replicate vessel were recorded at 24 and 48 hours of exposure and observed mortalities were removed from the test solutions Biological observations and observations from the physical characteristics of each replicate test solution and control were also made and recorded at 0 24 and 48 hours Dissolved oxygen concentrations pH and temperature were measured at test initiation and at 24-hour intervals thereafter in one replicate vessel (a) for each test concentration in which there were surviving organisms

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 13 SGS

Total hardness concentrations were measured by the EDTA titrimetric method and total alkalinity concentrations were determined by potentiometric titration to an endpoint of pH 45 (APHA 1989) Total residual chorine was measured by Hach test Concentrations of ammonia were determined using a Buchi model 212 distillation unit and titrated automatically with a Brinkman titroprocessor Specific conductivity was measured with a Cole Palmer Model 71250 salinityshyconductivity-temperature meter and probe pH was measured with a Fisher Scientific Accumet 910 pH meter and combination electrode dissolved oxygen concentration was measured with an YSI Model 59 dissolved oxygen meter Daily temperature measurements were performed with a Princo mercury thermometer and a Fisher minimum-maximum thermometer Light intensity was measured with a General Electric type 217 light meter

28 Reference Toxicity Test

A 48-hour reference toxicity test exposing Daphnia pulex to sodium chloride (NaCI) was conducted from December 2 2003 to December 4 2003 The reference test was conducted to establish the health of the test organisms The reference toxicity test included five NaCI concentrations and a dilution water control (moderately hard reconstituted water) The nominal NaCI concentrations for the test with Daphnia pulex ranged from 625 to 10000 mg of NaCIL Test methods were the same as those described above for the effluent test

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 14 SGS

30 Statistics

The concentration-response relationships observed were characterized by the median lethal concentrations (LC50) which is the concentration that is calculated to be lethal to 50 percent of the organisms within the test period If no concentration caused mortality of 50 then the LC50 value was determined to be greater than the highest concentration tested and no statistical analysis were performed If at least one concentration caused mortality of greater than 50 of the test population then a computer program (TOXSTAT 35) was used to calculate the LC50 value Three statistical methods were available in the computer program probit analysis the Trimmed Spearman-Karber and the Spearman-Karber methods The graphical method is available if appropriate Generally to choose the best estimate of the LC50 value for a particular data set the US EPA flow chart on page 15 was followed

The No-Observable-Acute-Effect-Level (NOAEL) was estimated for the acute toxicity test and is defined as the highest concentration of effluent that produced gt 90 survival

32 Cultures are renewed three times per week Organisms are fed daily

40 Obtaining Neonates for Testing

41 Cultures of Ceriodaphnia are started by placing one neonate into a 30 ml disposable plastic cup containing approximately 20 ml of Moderately Hard Synthetic Water New Ceriodaphnia cultures are started every ten to fourteen days D magna and D putex are replaced whenever mortality occurs

42 The individual cultures are transferred to fresh media three times per week Synthetic water algae and YCT are mixed prior to pouring into culture vessel to ensure uniformity of media The old media and neonates are kept for stock cultures for several weeks and then discarded

43 To assure neonates for chronic tests are of a very similar age transfer of individual brood stock to fresh media should be made the morning of the test The cultures are then checked approximately every two hours to find an adequate number of neonates all released with an 8 hour period For acute tests individuals are either transferred less than 24 hours before a test or the young are separated from adults less than 24 hours before a test

44 Young used in chronic testing are obtained from adults who have produced at least three broods with no less than 8 neonates in their third or subsequent brood Neonates are then distributed in a blocking procedure ie neonates from the same organism are placed in one replication of each concentration

i 10 Summary

To insure that healthy organisms are used in testing CTampE performs monthly QAQC tests on all in-house cultured organisms CTampE uses Sodium Chloride as a reference toxicant

20 Plmephales promelas

21 48 hour static acute toxicity tests are run at 20degC (plusmn1degC) using fish 1 to 14 days old

22 This test consists of a control and a dilution series of 10gL 9gL 8gL 7gL and 6gL of sodium chloride Other dilution series may be used

23 The dilutions are prepared in 800 ml disposable plastic beakers using moderately hard synthetic water 500 mis of test solution is placed in each of two replications Water quality values are measured and recorded at this time

24 Ten organisms are placed in each replicate Fish are loaded by first siphoning them into a shallow pan from which they are transferred to the beakers with a large bore pipette

25 The test is terminated at 48 hours At this time mortalities are recorded along with final water quality data

30 Daphnids (Ceriodaphnia dubia Daphnia magna Daphnia pulex)

31 48 hour static acute tests are performed at 25degC (plusmn1degC) using organisms less than 24 hours old

32 These tests consist of a control and a five dilution series The concentration of the reference toxicant is varied depending on species

34 Four organisms are placed in each test vessel The Daphnids are loaded with a disposable plastic pipette Organisms are gently released below the surface of the water to minimize risk of injury

35 The test is terminated at 48 hours At this time mortalities are recorded along with final water quality data

40 Data Analysis

41 Toxicity tests are conducted on a monthly basis

42 The LCso is calculated according to ERA protocols

43 Results from these tests are incorporated into Q-sum charts These records are kept in monthly files

b SamplingTest Results Received

See attached tables

Preliminary analytical results received in December 2003 from the fall 2003 GMA 4 interim groundwater quality monitoring activities are shown in Table 24-2 These preliminary results have been compared to the Method 1 GW-2 and GW-3 groundwater standards and UCLs for groundwater set forth in the MCP In these comparisons for PCBs and inorganics the filtered sample results were used for the comparisons to the Method 1 GW-3 standards (there are no GW-2 standards for these constituents) and the unfiltered sample results were used for the comparisons to UCLs These comparisons indicate the following

bull There were no exceedances of UCLs in any of the groundwater sample results received in December 2003

bull The MCP GW-2 standards were not exceeded in any of the GW-2 groundwater sample results received in December 2003

bull The MCP GW-3 standard for PCBs (00003 ppm) was slightly exceeded in the filtered sample from monitoring well OPCA-MW-8 This is the first such exceedance observed in this well No other MCP GW-3 standards were exceeded in any of the groundwater sample results received in December 2003

10 Introduction

11 Background

In 1972 amendments were made to the Clean Water Act (CWA) prohibiting the discharge of any pollutant from a point source to waters of the United States unless the discharge is authorized by a National Pollutant Discharge Elimination System (NPDES) permit Since the passing of the 1972 amendments to the CWA significant progress has been made in cleaning up industrial process wastewater and municipal sewage

The purpose of the National Pollutant Discharge Elimination System (NPDES) Program is to protect human health and the environment The Clean Water Act requires that all point sources discharging pollutants into waters of the United States must obtain an NPDES permit By point sources EPA means discrete conveyances such as pipes or man made ditches

For many years discharge limits were based on available technology for wastewater treatment However in 1984 the US Environmental Protection Agency (EPA) released a national policy statement entitled Policy for the Development of Water Quality-Based Permit Limitations for Toxic Pollutants (US EPA 1984) which addresses the control of toxic pollutants beyond technology-based requirements in order to meet water quality standards To implement the new policy guidance was provided to the respective state and regional permit personnel in the EPAs Technical Support Document for Water Quality-Based Toxics Control (US EPA 1985 US EPA 1991) The EPAs

policy statement and the support document recommended that where appropriate permit limits should be based on effluent toxicity as measured in aquatic toxicity tests

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 8SGS

12 Clean Water Act 33 USC ss 1251 et seq (1977)

The Clean Water Act is a 1977 amendment to the Federal Water Pollution Control Act of 1972 which set the basic structure for regulating discharges of pollutants to waters of the United States The law gave EPA the authority to set effluent standards on an industry basis (technology-based) and continued the requirements to set water quality standards for all contaminants in surface waters The CWA makes it unlawful for any person to discharge any pollutant from a point source into navigable waters unless a permit (NPDES) is obtained under the Act The 1977 amendments focused on toxic pollutants In 1987 the CWA was reauthorized and again focused on toxic substances authorized citizen suit provisions and funded sewage treatment plants (POTWs) under the Construction Grants Program The CWA provisions for the delegation by EPA of many permitting administrative and enforcement aspects of the law to state governments In states with the authority to implement CWA programs EPA still retains oversight responsibilities

13 Objective of the General Electric Study The objective of this study was to measure the acute toxicity of the composite wastewater discharged by the General Electric facility located in Pittsfield Massachusetts using Daphnia pufex under static conditions Whereas D pulex are not considered locally important they are routinely used by regulatory agencies and contract laboratories nationwide for toxicity testing A toxicity test was conducted from December 3 2003 to December 5 2003 at SGS Environmental Services Charleston West Virginia All original raw data and the final report produced for this study are stored in SGSs archives at the above location

20 Materials and Methods

21 Protocol

Procedures used in this acute toxicity test followed those described in the SGS Standard Operating Procedure (SOP) entitled Acute Aquatic Toxicity Testing SGS document control number 7002 version 40 This SOP generally follows the standard methodology presented in Methods for Measuring the Acute Toxicity of Effluents and Receiving Waters to Freshwater and Marine Organisms (US EPA 1993 Additional SOPs used in this study are outlined below

Dissolved oxygen concentration was recorded after sample was aerated and warmed to approximately 20degC)

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 10 SGS

The effluent sample was observed to be clear and colorless

23 Dilution Water

Dilution water consisted of receiving water collected from the Housatonic River The receiving water (A5287R) was collected by General Electric personnel on December 2 2003 Upon receipt at SGS on December 3 2003 the sample temperature was 34degC The dilution water was characterized as having

Dissolved oxygen concentration was recorded after sample was aerated and warmed to approximately 20degC)

The dilution water sample was observed to be slightly cloudy with a straw color

24 Reference Control Water Water used in the reference control vessels was deionized (DI) water adjusted to the appropriate hardness (moderately hard reconstituted water) by the addition

of reagent grade chemicals (US ERA 1993) Characterization of this water resulted in

Parameter Result Total Hardness 100 Alkalinity (as CaC03) 69 pH 712 Specific Conductance 324 Dissolved Oxygen 872

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 11 SGS

25 Test Organisms

Daphnids (Daphnia pulex) less than 24-hours old were obtained from SGS

laboratory cultures maintained in Charleston The culture system consisted of twenty-four (24) 100 ml disposable plastic beakers each containing 80 ml of culture medium and one (1) daphnid The culture medium was deionized (DI) water for which the hardness was raised by addition of reagent grade chemicals (US EPA 1993) Prior to use the culture water was characterized

Parameter Result Total Hardness within range of 80-110 mgL Alkalinity (as CaCO3) within range of 60-70 mgL pH within range of 70 to 72

The culture area was maintained at a temperature of 20degC (plusmn 1degC) with a

regulated photoperiod of 16 hours of light and 8 hours of darkness

Daphnid cultures were fed a combination of green algae (Setanastrum

capricorium] approximately 40 x 107 cellsml) and YCT (yeast cereal leaves and trout chow) Approximately 10 ml of algae and 05 ml of YCT was added to each culture vessel daily Three times per week daphnids are transferred to fresh culture media

Approximately twenty-four hours before test initiation all immature daphnids were removed from the culture flasks Offspring produced during the period were used in the toxicity test

26 Test Procedures

A subsample of the effluent and the dilution water (approximately 2250 ml) was analyzed by SGS for total phosphorus chloride total suspended solids and total solids The 48-hour toxicity test was conducted at concentrations of 100 75 50 35 15 and 5 effluent Test concentrations were prepared by diluting

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 12 SGS

the appropriate volume of effluent with dilution water to a total volume of 250 ml Test solutions were then divided into replicate (5 replicates per concentration) 30 ml medicine cups each containing 20 ml of test solution One set of five control beakers (containing Housatonic River water) and one set of five reference control beakers (containing moderately hard reconstituted water) were established and maintained under the same conditions as the exposure concentrations A secondary set of five reference control beakers (containing sodium thiosulfate) was also maintained Test solutions were placed in an incubator to maintain solution temperature of 20degC (plusmn 1degC) Light was provided on a 16-hour light and 8-hour dark photoperiod Florescent bulbs provided an illumination of 90 to 100 foot-candles in the test area

Prior to test initiation daphnids less than 24-hours old were culled individually with a plastic pipette and placed into a 1000 ml holding beaker containing approximately 500 ml of reference water The test was initiated when daphnids were individually transferred from the holding beaker to the test solutions (4 daphnids per replicate) The daphnids were fed prior to test initiation but were not fed during the exposure period

27 Test Monitoring

The number of mortalities and observations in each replicate vessel were recorded at 24 and 48 hours of exposure and observed mortalities were removed from the test solutions Biological observations and observations from the physical characteristics of each replicate test solution and control were also made and recorded at 0 24 and 48 hours Dissolved oxygen concentrations pH and temperature were measured at test initiation and at 24-hour intervals thereafter in one replicate vessel (a) for each test concentration in which there were surviving organisms

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 13 SGS

Total hardness concentrations were measured by the EDTA titrimetric method and total alkalinity concentrations were determined by potentiometric titration to an endpoint of pH 45 (APHA 1989) Total residual chorine was measured by Hach test Concentrations of ammonia were determined using a Buchi model 212 distillation unit and titrated automatically with a Brinkman titroprocessor Specific conductivity was measured with a Cole Palmer Model 71250 salinityshyconductivity-temperature meter and probe pH was measured with a Fisher Scientific Accumet 910 pH meter and combination electrode dissolved oxygen concentration was measured with an YSI Model 59 dissolved oxygen meter Daily temperature measurements were performed with a Princo mercury thermometer and a Fisher minimum-maximum thermometer Light intensity was measured with a General Electric type 217 light meter

28 Reference Toxicity Test

A 48-hour reference toxicity test exposing Daphnia pulex to sodium chloride (NaCI) was conducted from December 2 2003 to December 4 2003 The reference test was conducted to establish the health of the test organisms The reference toxicity test included five NaCI concentrations and a dilution water control (moderately hard reconstituted water) The nominal NaCI concentrations for the test with Daphnia pulex ranged from 625 to 10000 mg of NaCIL Test methods were the same as those described above for the effluent test

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 14 SGS

30 Statistics

The concentration-response relationships observed were characterized by the median lethal concentrations (LC50) which is the concentration that is calculated to be lethal to 50 percent of the organisms within the test period If no concentration caused mortality of 50 then the LC50 value was determined to be greater than the highest concentration tested and no statistical analysis were performed If at least one concentration caused mortality of greater than 50 of the test population then a computer program (TOXSTAT 35) was used to calculate the LC50 value Three statistical methods were available in the computer program probit analysis the Trimmed Spearman-Karber and the Spearman-Karber methods The graphical method is available if appropriate Generally to choose the best estimate of the LC50 value for a particular data set the US EPA flow chart on page 15 was followed

The No-Observable-Acute-Effect-Level (NOAEL) was estimated for the acute toxicity test and is defined as the highest concentration of effluent that produced gt 90 survival

10 Summary

This document describes the procedure for the culture of Ceriodaphnia dubia Daphnia pulex Daphnia magna that are used in aquatic toxicity testing

20 Mass Stock Cultures of Ceriodaphnia dubia Daphnia pulex and Daphnia magna

21 Stock cultures are maintained in 1000 ml beakersjars with 900 mis of culture media at 20 plusmn 1deg C These cultures are maintained only as a back-up source of organisms

22 Culture media for Ceriodaphnia dubia and Daphnia pulex is moderately-hard synthetic water Culture media for Daphnia magna is hard synthetic water (see document control number 700504 Culture Waters for Aquatic Toxicity Testing)

23 Many cultures are maintained simultaneously with an informal rotation cycle New cultures are started with young produced by individual cultures These cultures are maintained for approximately 3 weeks after which they are discarded

24 Cultures are fed YCT (yeast cerophyll digested trout chowflake food) and algae (Selanastrum capricorium) on Monday Wednesday and Friday Feeding as well as culture rotation temperature and all other relevant data is recorded by species in a log book

25 Stock cultures are also fed algae and YCT These feedings are recorded in the log book

30 Individual Cultures of Ceriodaphnia dubia Daphnia pulex Daphnia magna

31 Cultures of Daphnia magna and Daphnia pulex are maintained in 100 ml plastic beakers Twenty-four (24) beakers with one organism each are kept at all times to ensure continuous availability of neonates for testing Cultures of individual Ceriodaphnia dubia are maintained in 30 ml sterile plastic medicine cups One to two cultures of approximately 100 organisms each are kept at all times

Document Control Number 7006 Page 2 of 3______________________________________________

32 Cultures are renewed three times per week Organisms are fed daily

40 Obtaining Neonates for Testing

41 Cultures of Ceriodaphnia are started by placing one neonate into a 30 ml disposable plastic cup containing approximately 20 ml of Moderately Hard Synthetic Water New Ceriodaphnia cultures are started every ten to fourteen days D magna and D putex are replaced whenever mortality occurs

42 The individual cultures are transferred to fresh media three times per week Synthetic water algae and YCT are mixed prior to pouring into culture vessel to ensure uniformity of media The old media and neonates are kept for stock cultures for several weeks and then discarded

43 To assure neonates for chronic tests are of a very similar age transfer of individual brood stock to fresh media should be made the morning of the test The cultures are then checked approximately every two hours to find an adequate number of neonates all released with an 8 hour period For acute tests individuals are either transferred less than 24 hours before a test or the young are separated from adults less than 24 hours before a test

44 Young used in chronic testing are obtained from adults who have produced at least three broods with no less than 8 neonates in their third or subsequent brood Neonates are then distributed in a blocking procedure ie neonates from the same organism are placed in one replication of each concentration

50 DAPHNIA Food

51 Digested Flake Food

511 Add 5g flake food to 1 L deionized water Mix well in a blender and place in a 2 L separatory funnel To digest aerate this mixture at room temperature for one week

a Activities UndertakenCompleted

Completed semi-annual groundwater sampling and analysis including re-collection of sample from OPCA-MW-4 for analysis of dioxinsfurans (original sample damaged at laboratory)

b SamplingTest Results Received

See attached tables

Preliminary analytical results received in December 2003 from the fall 2003 GMA 4 interim groundwater quality monitoring activities are shown in Table 24-2 These preliminary results have been compared to the Method 1 GW-2 and GW-3 groundwater standards and UCLs for groundwater set forth in the MCP In these comparisons for PCBs and inorganics the filtered sample results were used for the comparisons to the Method 1 GW-3 standards (there are no GW-2 standards for these constituents) and the unfiltered sample results were used for the comparisons to UCLs These comparisons indicate the following

bull There were no exceedances of UCLs in any of the groundwater sample results received in December 2003

bull The MCP GW-2 standards were not exceeded in any of the GW-2 groundwater sample results received in December 2003

bull The MCP GW-3 standard for PCBs (00003 ppm) was slightly exceeded in the filtered sample from monitoring well OPCA-MW-8 This is the first such exceedance observed in this well No other MCP GW-3 standards were exceeded in any of the groundwater sample results received in December 2003

10 Introduction

11 Background

In 1972 amendments were made to the Clean Water Act (CWA) prohibiting the discharge of any pollutant from a point source to waters of the United States unless the discharge is authorized by a National Pollutant Discharge Elimination System (NPDES) permit Since the passing of the 1972 amendments to the CWA significant progress has been made in cleaning up industrial process wastewater and municipal sewage

The purpose of the National Pollutant Discharge Elimination System (NPDES) Program is to protect human health and the environment The Clean Water Act requires that all point sources discharging pollutants into waters of the United States must obtain an NPDES permit By point sources EPA means discrete conveyances such as pipes or man made ditches

For many years discharge limits were based on available technology for wastewater treatment However in 1984 the US Environmental Protection Agency (EPA) released a national policy statement entitled Policy for the Development of Water Quality-Based Permit Limitations for Toxic Pollutants (US EPA 1984) which addresses the control of toxic pollutants beyond technology-based requirements in order to meet water quality standards To implement the new policy guidance was provided to the respective state and regional permit personnel in the EPAs Technical Support Document for Water Quality-Based Toxics Control (US EPA 1985 US EPA 1991) The EPAs

policy statement and the support document recommended that where appropriate permit limits should be based on effluent toxicity as measured in aquatic toxicity tests

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 8SGS

12 Clean Water Act 33 USC ss 1251 et seq (1977)

The Clean Water Act is a 1977 amendment to the Federal Water Pollution Control Act of 1972 which set the basic structure for regulating discharges of pollutants to waters of the United States The law gave EPA the authority to set effluent standards on an industry basis (technology-based) and continued the requirements to set water quality standards for all contaminants in surface waters The CWA makes it unlawful for any person to discharge any pollutant from a point source into navigable waters unless a permit (NPDES) is obtained under the Act The 1977 amendments focused on toxic pollutants In 1987 the CWA was reauthorized and again focused on toxic substances authorized citizen suit provisions and funded sewage treatment plants (POTWs) under the Construction Grants Program The CWA provisions for the delegation by EPA of many permitting administrative and enforcement aspects of the law to state governments In states with the authority to implement CWA programs EPA still retains oversight responsibilities

13 Objective of the General Electric Study The objective of this study was to measure the acute toxicity of the composite wastewater discharged by the General Electric facility located in Pittsfield Massachusetts using Daphnia pufex under static conditions Whereas D pulex are not considered locally important they are routinely used by regulatory agencies and contract laboratories nationwide for toxicity testing A toxicity test was conducted from December 3 2003 to December 5 2003 at SGS Environmental Services Charleston West Virginia All original raw data and the final report produced for this study are stored in SGSs archives at the above location

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 10 SGS

The effluent sample was observed to be clear and colorless

23 Dilution Water

Dilution water consisted of receiving water collected from the Housatonic River The receiving water (A5287R) was collected by General Electric personnel on December 2 2003 Upon receipt at SGS on December 3 2003 the sample temperature was 34degC The dilution water was characterized as having

The dilution water sample was observed to be slightly cloudy with a straw color

24 Reference Control Water Water used in the reference control vessels was deionized (DI) water adjusted to the appropriate hardness (moderately hard reconstituted water) by the addition

of reagent grade chemicals (US ERA 1993) Characterization of this water resulted in

Parameter Result Total Hardness 100 Alkalinity (as CaC03) 69 pH 712 Specific Conductance 324 Dissolved Oxygen 872

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 11 SGS

25 Test Organisms

Daphnids (Daphnia pulex) less than 24-hours old were obtained from SGS

laboratory cultures maintained in Charleston The culture system consisted of twenty-four (24) 100 ml disposable plastic beakers each containing 80 ml of culture medium and one (1) daphnid The culture medium was deionized (DI) water for which the hardness was raised by addition of reagent grade chemicals (US EPA 1993) Prior to use the culture water was characterized

Parameter Result Total Hardness within range of 80-110 mgL Alkalinity (as CaCO3) within range of 60-70 mgL pH within range of 70 to 72

The culture area was maintained at a temperature of 20degC (plusmn 1degC) with a

regulated photoperiod of 16 hours of light and 8 hours of darkness

Daphnid cultures were fed a combination of green algae (Setanastrum

capricorium] approximately 40 x 107 cellsml) and YCT (yeast cereal leaves and trout chow) Approximately 10 ml of algae and 05 ml of YCT was added to each culture vessel daily Three times per week daphnids are transferred to fresh culture media

Approximately twenty-four hours before test initiation all immature daphnids were removed from the culture flasks Offspring produced during the period were used in the toxicity test

26 Test Procedures

A subsample of the effluent and the dilution water (approximately 2250 ml) was analyzed by SGS for total phosphorus chloride total suspended solids and total solids The 48-hour toxicity test was conducted at concentrations of 100 75 50 35 15 and 5 effluent Test concentrations were prepared by diluting

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 12 SGS

the appropriate volume of effluent with dilution water to a total volume of 250 ml Test solutions were then divided into replicate (5 replicates per concentration) 30 ml medicine cups each containing 20 ml of test solution One set of five control beakers (containing Housatonic River water) and one set of five reference control beakers (containing moderately hard reconstituted water) were established and maintained under the same conditions as the exposure concentrations A secondary set of five reference control beakers (containing sodium thiosulfate) was also maintained Test solutions were placed in an incubator to maintain solution temperature of 20degC (plusmn 1degC) Light was provided on a 16-hour light and 8-hour dark photoperiod Florescent bulbs provided an illumination of 90 to 100 foot-candles in the test area

Prior to test initiation daphnids less than 24-hours old were culled individually with a plastic pipette and placed into a 1000 ml holding beaker containing approximately 500 ml of reference water The test was initiated when daphnids were individually transferred from the holding beaker to the test solutions (4 daphnids per replicate) The daphnids were fed prior to test initiation but were not fed during the exposure period

27 Test Monitoring

The number of mortalities and observations in each replicate vessel were recorded at 24 and 48 hours of exposure and observed mortalities were removed from the test solutions Biological observations and observations from the physical characteristics of each replicate test solution and control were also made and recorded at 0 24 and 48 hours Dissolved oxygen concentrations pH and temperature were measured at test initiation and at 24-hour intervals thereafter in one replicate vessel (a) for each test concentration in which there were surviving organisms

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 13 SGS

Total hardness concentrations were measured by the EDTA titrimetric method and total alkalinity concentrations were determined by potentiometric titration to an endpoint of pH 45 (APHA 1989) Total residual chorine was measured by Hach test Concentrations of ammonia were determined using a Buchi model 212 distillation unit and titrated automatically with a Brinkman titroprocessor Specific conductivity was measured with a Cole Palmer Model 71250 salinityshyconductivity-temperature meter and probe pH was measured with a Fisher Scientific Accumet 910 pH meter and combination electrode dissolved oxygen concentration was measured with an YSI Model 59 dissolved oxygen meter Daily temperature measurements were performed with a Princo mercury thermometer and a Fisher minimum-maximum thermometer Light intensity was measured with a General Electric type 217 light meter

28 Reference Toxicity Test

A 48-hour reference toxicity test exposing Daphnia pulex to sodium chloride (NaCI) was conducted from December 2 2003 to December 4 2003 The reference test was conducted to establish the health of the test organisms The reference toxicity test included five NaCI concentrations and a dilution water control (moderately hard reconstituted water) The nominal NaCI concentrations for the test with Daphnia pulex ranged from 625 to 10000 mg of NaCIL Test methods were the same as those described above for the effluent test

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 14 SGS

30 Statistics

The concentration-response relationships observed were characterized by the median lethal concentrations (LC50) which is the concentration that is calculated to be lethal to 50 percent of the organisms within the test period If no concentration caused mortality of 50 then the LC50 value was determined to be greater than the highest concentration tested and no statistical analysis were performed If at least one concentration caused mortality of greater than 50 of the test population then a computer program (TOXSTAT 35) was used to calculate the LC50 value Three statistical methods were available in the computer program probit analysis the Trimmed Spearman-Karber and the Spearman-Karber methods The graphical method is available if appropriate Generally to choose the best estimate of the LC50 value for a particular data set the US EPA flow chart on page 15 was followed

The No-Observable-Acute-Effect-Level (NOAEL) was estimated for the acute toxicity test and is defined as the highest concentration of effluent that produced gt 90 survival

10 Summary

This document describes the procedure for the culture of Ceriodaphnia dubia Daphnia pulex Daphnia magna that are used in aquatic toxicity testing

20 Mass Stock Cultures of Ceriodaphnia dubia Daphnia pulex and Daphnia magna

21 Stock cultures are maintained in 1000 ml beakersjars with 900 mis of culture media at 20 plusmn 1deg C These cultures are maintained only as a back-up source of organisms

22 Culture media for Ceriodaphnia dubia and Daphnia pulex is moderately-hard synthetic water Culture media for Daphnia magna is hard synthetic water (see document control number 700504 Culture Waters for Aquatic Toxicity Testing)

23 Many cultures are maintained simultaneously with an informal rotation cycle New cultures are started with young produced by individual cultures These cultures are maintained for approximately 3 weeks after which they are discarded

24 Cultures are fed YCT (yeast cerophyll digested trout chowflake food) and algae (Selanastrum capricorium) on Monday Wednesday and Friday Feeding as well as culture rotation temperature and all other relevant data is recorded by species in a log book

25 Stock cultures are also fed algae and YCT These feedings are recorded in the log book

30 Individual Cultures of Ceriodaphnia dubia Daphnia pulex Daphnia magna

31 Cultures of Daphnia magna and Daphnia pulex are maintained in 100 ml plastic beakers Twenty-four (24) beakers with one organism each are kept at all times to ensure continuous availability of neonates for testing Cultures of individual Ceriodaphnia dubia are maintained in 30 ml sterile plastic medicine cups One to two cultures of approximately 100 organisms each are kept at all times

Document Control Number 7006 Page 2 of 3______________________________________________

32 Cultures are renewed three times per week Organisms are fed daily

40 Obtaining Neonates for Testing

41 Cultures of Ceriodaphnia are started by placing one neonate into a 30 ml disposable plastic cup containing approximately 20 ml of Moderately Hard Synthetic Water New Ceriodaphnia cultures are started every ten to fourteen days D magna and D putex are replaced whenever mortality occurs

42 The individual cultures are transferred to fresh media three times per week Synthetic water algae and YCT are mixed prior to pouring into culture vessel to ensure uniformity of media The old media and neonates are kept for stock cultures for several weeks and then discarded

43 To assure neonates for chronic tests are of a very similar age transfer of individual brood stock to fresh media should be made the morning of the test The cultures are then checked approximately every two hours to find an adequate number of neonates all released with an 8 hour period For acute tests individuals are either transferred less than 24 hours before a test or the young are separated from adults less than 24 hours before a test

44 Young used in chronic testing are obtained from adults who have produced at least three broods with no less than 8 neonates in their third or subsequent brood Neonates are then distributed in a blocking procedure ie neonates from the same organism are placed in one replication of each concentration

50 DAPHNIA Food

51 Digested Flake Food

511 Add 5g flake food to 1 L deionized water Mix well in a blender and place in a 2 L separatory funnel To digest aerate this mixture at room temperature for one week

See attached tables

Preliminary analytical results received in December 2003 from the fall 2003 GMA 4 interim groundwater quality monitoring activities are shown in Table 24-2 These preliminary results have been compared to the Method 1 GW-2 and GW-3 groundwater standards and UCLs for groundwater set forth in the MCP In these comparisons for PCBs and inorganics the filtered sample results were used for the comparisons to the Method 1 GW-3 standards (there are no GW-2 standards for these constituents) and the unfiltered sample results were used for the comparisons to UCLs These comparisons indicate the following

bull There were no exceedances of UCLs in any of the groundwater sample results received in December 2003

bull The MCP GW-2 standards were not exceeded in any of the GW-2 groundwater sample results received in December 2003

bull The MCP GW-3 standard for PCBs (00003 ppm) was slightly exceeded in the filtered sample from monitoring well OPCA-MW-8 This is the first such exceedance observed in this well No other MCP GW-3 standards were exceeded in any of the groundwater sample results received in December 2003

10 Introduction

11 Background

In 1972 amendments were made to the Clean Water Act (CWA) prohibiting the discharge of any pollutant from a point source to waters of the United States unless the discharge is authorized by a National Pollutant Discharge Elimination System (NPDES) permit Since the passing of the 1972 amendments to the CWA significant progress has been made in cleaning up industrial process wastewater and municipal sewage

The purpose of the National Pollutant Discharge Elimination System (NPDES) Program is to protect human health and the environment The Clean Water Act requires that all point sources discharging pollutants into waters of the United States must obtain an NPDES permit By point sources EPA means discrete conveyances such as pipes or man made ditches

For many years discharge limits were based on available technology for wastewater treatment However in 1984 the US Environmental Protection Agency (EPA) released a national policy statement entitled Policy for the Development of Water Quality-Based Permit Limitations for Toxic Pollutants (US EPA 1984) which addresses the control of toxic pollutants beyond technology-based requirements in order to meet water quality standards To implement the new policy guidance was provided to the respective state and regional permit personnel in the EPAs Technical Support Document for Water Quality-Based Toxics Control (US EPA 1985 US EPA 1991) The EPAs

policy statement and the support document recommended that where appropriate permit limits should be based on effluent toxicity as measured in aquatic toxicity tests

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 8SGS

12 Clean Water Act 33 USC ss 1251 et seq (1977)

The Clean Water Act is a 1977 amendment to the Federal Water Pollution Control Act of 1972 which set the basic structure for regulating discharges of pollutants to waters of the United States The law gave EPA the authority to set effluent standards on an industry basis (technology-based) and continued the requirements to set water quality standards for all contaminants in surface waters The CWA makes it unlawful for any person to discharge any pollutant from a point source into navigable waters unless a permit (NPDES) is obtained under the Act The 1977 amendments focused on toxic pollutants In 1987 the CWA was reauthorized and again focused on toxic substances authorized citizen suit provisions and funded sewage treatment plants (POTWs) under the Construction Grants Program The CWA provisions for the delegation by EPA of many permitting administrative and enforcement aspects of the law to state governments In states with the authority to implement CWA programs EPA still retains oversight responsibilities

13 Objective of the General Electric Study The objective of this study was to measure the acute toxicity of the composite wastewater discharged by the General Electric facility located in Pittsfield Massachusetts using Daphnia pufex under static conditions Whereas D pulex are not considered locally important they are routinely used by regulatory agencies and contract laboratories nationwide for toxicity testing A toxicity test was conducted from December 3 2003 to December 5 2003 at SGS Environmental Services Charleston West Virginia All original raw data and the final report produced for this study are stored in SGSs archives at the above location

25 Test Organisms

Daphnids (Daphnia pulex) less than 24-hours old were obtained from SGS

laboratory cultures maintained in Charleston The culture system consisted of twenty-four (24) 100 ml disposable plastic beakers each containing 80 ml of culture medium and one (1) daphnid The culture medium was deionized (DI) water for which the hardness was raised by addition of reagent grade chemicals (US EPA 1993) Prior to use the culture water was characterized

Parameter Result Total Hardness within range of 80-110 mgL Alkalinity (as CaCO3) within range of 60-70 mgL pH within range of 70 to 72

The culture area was maintained at a temperature of 20degC (plusmn 1degC) with a

regulated photoperiod of 16 hours of light and 8 hours of darkness

Daphnid cultures were fed a combination of green algae (Setanastrum

capricorium] approximately 40 x 107 cellsml) and YCT (yeast cereal leaves and trout chow) Approximately 10 ml of algae and 05 ml of YCT was added to each culture vessel daily Three times per week daphnids are transferred to fresh culture media

Approximately twenty-four hours before test initiation all immature daphnids were removed from the culture flasks Offspring produced during the period were used in the toxicity test

26 Test Procedures

A subsample of the effluent and the dilution water (approximately 2250 ml) was analyzed by SGS for total phosphorus chloride total suspended solids and total solids The 48-hour toxicity test was conducted at concentrations of 100 75 50 35 15 and 5 effluent Test concentrations were prepared by diluting

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 12 SGS

the appropriate volume of effluent with dilution water to a total volume of 250 ml Test solutions were then divided into replicate (5 replicates per concentration) 30 ml medicine cups each containing 20 ml of test solution One set of five control beakers (containing Housatonic River water) and one set of five reference control beakers (containing moderately hard reconstituted water) were established and maintained under the same conditions as the exposure concentrations A secondary set of five reference control beakers (containing sodium thiosulfate) was also maintained Test solutions were placed in an incubator to maintain solution temperature of 20degC (plusmn 1degC) Light was provided on a 16-hour light and 8-hour dark photoperiod Florescent bulbs provided an illumination of 90 to 100 foot-candles in the test area

Prior to test initiation daphnids less than 24-hours old were culled individually with a plastic pipette and placed into a 1000 ml holding beaker containing approximately 500 ml of reference water The test was initiated when daphnids were individually transferred from the holding beaker to the test solutions (4 daphnids per replicate) The daphnids were fed prior to test initiation but were not fed during the exposure period

27 Test Monitoring

The number of mortalities and observations in each replicate vessel were recorded at 24 and 48 hours of exposure and observed mortalities were removed from the test solutions Biological observations and observations from the physical characteristics of each replicate test solution and control were also made and recorded at 0 24 and 48 hours Dissolved oxygen concentrations pH and temperature were measured at test initiation and at 24-hour intervals thereafter in one replicate vessel (a) for each test concentration in which there were surviving organisms

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 13 SGS

Total hardness concentrations were measured by the EDTA titrimetric method and total alkalinity concentrations were determined by potentiometric titration to an endpoint of pH 45 (APHA 1989) Total residual chorine was measured by Hach test Concentrations of ammonia were determined using a Buchi model 212 distillation unit and titrated automatically with a Brinkman titroprocessor Specific conductivity was measured with a Cole Palmer Model 71250 salinityshyconductivity-temperature meter and probe pH was measured with a Fisher Scientific Accumet 910 pH meter and combination electrode dissolved oxygen concentration was measured with an YSI Model 59 dissolved oxygen meter Daily temperature measurements were performed with a Princo mercury thermometer and a Fisher minimum-maximum thermometer Light intensity was measured with a General Electric type 217 light meter

28 Reference Toxicity Test

A 48-hour reference toxicity test exposing Daphnia pulex to sodium chloride (NaCI) was conducted from December 2 2003 to December 4 2003 The reference test was conducted to establish the health of the test organisms The reference toxicity test included five NaCI concentrations and a dilution water control (moderately hard reconstituted water) The nominal NaCI concentrations for the test with Daphnia pulex ranged from 625 to 10000 mg of NaCIL Test methods were the same as those described above for the effluent test

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 14 SGS

30 Statistics

The concentration-response relationships observed were characterized by the median lethal concentrations (LC50) which is the concentration that is calculated to be lethal to 50 percent of the organisms within the test period If no concentration caused mortality of 50 then the LC50 value was determined to be greater than the highest concentration tested and no statistical analysis were performed If at least one concentration caused mortality of greater than 50 of the test population then a computer program (TOXSTAT 35) was used to calculate the LC50 value Three statistical methods were available in the computer program probit analysis the Trimmed Spearman-Karber and the Spearman-Karber methods The graphical method is available if appropriate Generally to choose the best estimate of the LC50 value for a particular data set the US EPA flow chart on page 15 was followed

The No-Observable-Acute-Effect-Level (NOAEL) was estimated for the acute toxicity test and is defined as the highest concentration of effluent that produced gt 90 survival

This document describes the procedure for the culture of Ceriodaphnia dubia Daphnia pulex Daphnia magna that are used in aquatic toxicity testing

20 Mass Stock Cultures of Ceriodaphnia dubia Daphnia pulex and Daphnia magna

21 Stock cultures are maintained in 1000 ml beakersjars with 900 mis of culture media at 20 plusmn 1deg C These cultures are maintained only as a back-up source of organisms

22 Culture media for Ceriodaphnia dubia and Daphnia pulex is moderately-hard synthetic water Culture media for Daphnia magna is hard synthetic water (see document control number 700504 Culture Waters for Aquatic Toxicity Testing)

23 Many cultures are maintained simultaneously with an informal rotation cycle New cultures are started with young produced by individual cultures These cultures are maintained for approximately 3 weeks after which they are discarded

24 Cultures are fed YCT (yeast cerophyll digested trout chowflake food) and algae (Selanastrum capricorium) on Monday Wednesday and Friday Feeding as well as culture rotation temperature and all other relevant data is recorded by species in a log book

25 Stock cultures are also fed algae and YCT These feedings are recorded in the log book

30 Individual Cultures of Ceriodaphnia dubia Daphnia pulex Daphnia magna

31 Cultures of Daphnia magna and Daphnia pulex are maintained in 100 ml plastic beakers Twenty-four (24) beakers with one organism each are kept at all times to ensure continuous availability of neonates for testing Cultures of individual Ceriodaphnia dubia are maintained in 30 ml sterile plastic medicine cups One to two cultures of approximately 100 organisms each are kept at all times

Document Control Number 7006 Page 2 of 3______________________________________________

32 Cultures are renewed three times per week Organisms are fed daily

40 Obtaining Neonates for Testing

41 Cultures of Ceriodaphnia are started by placing one neonate into a 30 ml disposable plastic cup containing approximately 20 ml of Moderately Hard Synthetic Water New Ceriodaphnia cultures are started every ten to fourteen days D magna and D putex are replaced whenever mortality occurs

42 The individual cultures are transferred to fresh media three times per week Synthetic water algae and YCT are mixed prior to pouring into culture vessel to ensure uniformity of media The old media and neonates are kept for stock cultures for several weeks and then discarded

43 To assure neonates for chronic tests are of a very similar age transfer of individual brood stock to fresh media should be made the morning of the test The cultures are then checked approximately every two hours to find an adequate number of neonates all released with an 8 hour period For acute tests individuals are either transferred less than 24 hours before a test or the young are separated from adults less than 24 hours before a test

44 Young used in chronic testing are obtained from adults who have produced at least three broods with no less than 8 neonates in their third or subsequent brood Neonates are then distributed in a blocking procedure ie neonates from the same organism are placed in one replication of each concentration

i 10 Summary

To insure that healthy organisms are used in testing CTampE performs monthly QAQC tests on all in-house cultured organisms CTampE uses Sodium Chloride as a reference toxicant

20 Plmephales promelas

21 48 hour static acute toxicity tests are run at 20degC (plusmn1degC) using fish 1 to 14 days old

22 This test consists of a control and a dilution series of 10gL 9gL 8gL 7gL and 6gL of sodium chloride Other dilution series may be used

23 The dilutions are prepared in 800 ml disposable plastic beakers using moderately hard synthetic water 500 mis of test solution is placed in each of two replications Water quality values are measured and recorded at this time

24 Ten organisms are placed in each replicate Fish are loaded by first siphoning them into a shallow pan from which they are transferred to the beakers with a large bore pipette

25 The test is terminated at 48 hours At this time mortalities are recorded along with final water quality data

30 Daphnids (Ceriodaphnia dubia Daphnia magna Daphnia pulex)

31 48 hour static acute tests are performed at 25degC (plusmn1degC) using organisms less than 24 hours old

32 These tests consist of a control and a five dilution series The concentration of the reference toxicant is varied depending on species

Completed semi-annual groundwater sampling and analysis including re-collection of sample from OPCA-MW-4 for analysis of dioxinsfurans (original sample damaged at laboratory)

b SamplingTest Results Received

See attached tables

Preliminary analytical results received in December 2003 from the fall 2003 GMA 4 interim groundwater quality monitoring activities are shown in Table 24-2 These preliminary results have been compared to the Method 1 GW-2 and GW-3 groundwater standards and UCLs for groundwater set forth in the MCP In these comparisons for PCBs and inorganics the filtered sample results were used for the comparisons to the Method 1 GW-3 standards (there are no GW-2 standards for these constituents) and the unfiltered sample results were used for the comparisons to UCLs These comparisons indicate the following

bull There were no exceedances of UCLs in any of the groundwater sample results received in December 2003

bull The MCP GW-2 standards were not exceeded in any of the GW-2 groundwater sample results received in December 2003

bull The MCP GW-3 standard for PCBs (00003 ppm) was slightly exceeded in the filtered sample from monitoring well OPCA-MW-8 This is the first such exceedance observed in this well No other MCP GW-3 standards were exceeded in any of the groundwater sample results received in December 2003

10 Introduction

11 Background

In 1972 amendments were made to the Clean Water Act (CWA) prohibiting the discharge of any pollutant from a point source to waters of the United States unless the discharge is authorized by a National Pollutant Discharge Elimination System (NPDES) permit Since the passing of the 1972 amendments to the CWA significant progress has been made in cleaning up industrial process wastewater and municipal sewage

The purpose of the National Pollutant Discharge Elimination System (NPDES) Program is to protect human health and the environment The Clean Water Act requires that all point sources discharging pollutants into waters of the United States must obtain an NPDES permit By point sources EPA means discrete conveyances such as pipes or man made ditches

For many years discharge limits were based on available technology for wastewater treatment However in 1984 the US Environmental Protection Agency (EPA) released a national policy statement entitled Policy for the Development of Water Quality-Based Permit Limitations for Toxic Pollutants (US EPA 1984) which addresses the control of toxic pollutants beyond technology-based requirements in order to meet water quality standards To implement the new policy guidance was provided to the respective state and regional permit personnel in the EPAs Technical Support Document for Water Quality-Based Toxics Control (US EPA 1985 US EPA 1991) The EPAs

policy statement and the support document recommended that where appropriate permit limits should be based on effluent toxicity as measured in aquatic toxicity tests

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 8SGS

12 Clean Water Act 33 USC ss 1251 et seq (1977)

The Clean Water Act is a 1977 amendment to the Federal Water Pollution Control Act of 1972 which set the basic structure for regulating discharges of pollutants to waters of the United States The law gave EPA the authority to set effluent standards on an industry basis (technology-based) and continued the requirements to set water quality standards for all contaminants in surface waters The CWA makes it unlawful for any person to discharge any pollutant from a point source into navigable waters unless a permit (NPDES) is obtained under the Act The 1977 amendments focused on toxic pollutants In 1987 the CWA was reauthorized and again focused on toxic substances authorized citizen suit provisions and funded sewage treatment plants (POTWs) under the Construction Grants Program The CWA provisions for the delegation by EPA of many permitting administrative and enforcement aspects of the law to state governments In states with the authority to implement CWA programs EPA still retains oversight responsibilities

13 Objective of the General Electric Study The objective of this study was to measure the acute toxicity of the composite wastewater discharged by the General Electric facility located in Pittsfield Massachusetts using Daphnia pufex under static conditions Whereas D pulex are not considered locally important they are routinely used by regulatory agencies and contract laboratories nationwide for toxicity testing A toxicity test was conducted from December 3 2003 to December 5 2003 at SGS Environmental Services Charleston West Virginia All original raw data and the final report produced for this study are stored in SGSs archives at the above location

Dissolved oxygen concentration was recorded after sample was aerated and warmed to approximately 20degC)

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 10 SGS

The effluent sample was observed to be clear and colorless

23 Dilution Water

Dilution water consisted of receiving water collected from the Housatonic River The receiving water (A5287R) was collected by General Electric personnel on December 2 2003 Upon receipt at SGS on December 3 2003 the sample temperature was 34degC The dilution water was characterized as having

Dissolved oxygen concentration was recorded after sample was aerated and warmed to approximately 20degC)

The dilution water sample was observed to be slightly cloudy with a straw color

24 Reference Control Water Water used in the reference control vessels was deionized (DI) water adjusted to the appropriate hardness (moderately hard reconstituted water) by the addition

of reagent grade chemicals (US ERA 1993) Characterization of this water resulted in

Parameter Result Total Hardness 100 Alkalinity (as CaC03) 69 pH 712 Specific Conductance 324 Dissolved Oxygen 872

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 11 SGS

25 Test Organisms

Daphnids (Daphnia pulex) less than 24-hours old were obtained from SGS

laboratory cultures maintained in Charleston The culture system consisted of twenty-four (24) 100 ml disposable plastic beakers each containing 80 ml of culture medium and one (1) daphnid The culture medium was deionized (DI) water for which the hardness was raised by addition of reagent grade chemicals (US EPA 1993) Prior to use the culture water was characterized

Parameter Result Total Hardness within range of 80-110 mgL Alkalinity (as CaCO3) within range of 60-70 mgL pH within range of 70 to 72

The culture area was maintained at a temperature of 20degC (plusmn 1degC) with a

regulated photoperiod of 16 hours of light and 8 hours of darkness

Daphnid cultures were fed a combination of green algae (Setanastrum

capricorium] approximately 40 x 107 cellsml) and YCT (yeast cereal leaves and trout chow) Approximately 10 ml of algae and 05 ml of YCT was added to each culture vessel daily Three times per week daphnids are transferred to fresh culture media

Approximately twenty-four hours before test initiation all immature daphnids were removed from the culture flasks Offspring produced during the period were used in the toxicity test

26 Test Procedures

A subsample of the effluent and the dilution water (approximately 2250 ml) was analyzed by SGS for total phosphorus chloride total suspended solids and total solids The 48-hour toxicity test was conducted at concentrations of 100 75 50 35 15 and 5 effluent Test concentrations were prepared by diluting

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 12 SGS

the appropriate volume of effluent with dilution water to a total volume of 250 ml Test solutions were then divided into replicate (5 replicates per concentration) 30 ml medicine cups each containing 20 ml of test solution One set of five control beakers (containing Housatonic River water) and one set of five reference control beakers (containing moderately hard reconstituted water) were established and maintained under the same conditions as the exposure concentrations A secondary set of five reference control beakers (containing sodium thiosulfate) was also maintained Test solutions were placed in an incubator to maintain solution temperature of 20degC (plusmn 1degC) Light was provided on a 16-hour light and 8-hour dark photoperiod Florescent bulbs provided an illumination of 90 to 100 foot-candles in the test area

Prior to test initiation daphnids less than 24-hours old were culled individually with a plastic pipette and placed into a 1000 ml holding beaker containing approximately 500 ml of reference water The test was initiated when daphnids were individually transferred from the holding beaker to the test solutions (4 daphnids per replicate) The daphnids were fed prior to test initiation but were not fed during the exposure period

27 Test Monitoring

The number of mortalities and observations in each replicate vessel were recorded at 24 and 48 hours of exposure and observed mortalities were removed from the test solutions Biological observations and observations from the physical characteristics of each replicate test solution and control were also made and recorded at 0 24 and 48 hours Dissolved oxygen concentrations pH and temperature were measured at test initiation and at 24-hour intervals thereafter in one replicate vessel (a) for each test concentration in which there were surviving organisms

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 13 SGS

Total hardness concentrations were measured by the EDTA titrimetric method and total alkalinity concentrations were determined by potentiometric titration to an endpoint of pH 45 (APHA 1989) Total residual chorine was measured by Hach test Concentrations of ammonia were determined using a Buchi model 212 distillation unit and titrated automatically with a Brinkman titroprocessor Specific conductivity was measured with a Cole Palmer Model 71250 salinityshyconductivity-temperature meter and probe pH was measured with a Fisher Scientific Accumet 910 pH meter and combination electrode dissolved oxygen concentration was measured with an YSI Model 59 dissolved oxygen meter Daily temperature measurements were performed with a Princo mercury thermometer and a Fisher minimum-maximum thermometer Light intensity was measured with a General Electric type 217 light meter

28 Reference Toxicity Test

A 48-hour reference toxicity test exposing Daphnia pulex to sodium chloride (NaCI) was conducted from December 2 2003 to December 4 2003 The reference test was conducted to establish the health of the test organisms The reference toxicity test included five NaCI concentrations and a dilution water control (moderately hard reconstituted water) The nominal NaCI concentrations for the test with Daphnia pulex ranged from 625 to 10000 mg of NaCIL Test methods were the same as those described above for the effluent test

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 14 SGS

30 Statistics

The concentration-response relationships observed were characterized by the median lethal concentrations (LC50) which is the concentration that is calculated to be lethal to 50 percent of the organisms within the test period If no concentration caused mortality of 50 then the LC50 value was determined to be greater than the highest concentration tested and no statistical analysis were performed If at least one concentration caused mortality of greater than 50 of the test population then a computer program (TOXSTAT 35) was used to calculate the LC50 value Three statistical methods were available in the computer program probit analysis the Trimmed Spearman-Karber and the Spearman-Karber methods The graphical method is available if appropriate Generally to choose the best estimate of the LC50 value for a particular data set the US EPA flow chart on page 15 was followed

The No-Observable-Acute-Effect-Level (NOAEL) was estimated for the acute toxicity test and is defined as the highest concentration of effluent that produced gt 90 survival

effluent is dechlorinated and the other is not (Dechlorination may be prohibited permit is checked to determine if dechlorination is allowed) The effluent is dechlorinated by the addition of anhydrous sodium thiosulfate The measured amount is recorded on the bench sheet Care is taken to add the least amount of sodium thiosulfate needed to decrease the TRC level below 010 mgL Typically adjustment of effluent is unnecessary

322 Twenty organisms per concentration are used in acute screening tests

323 This is a static non-renewal test using Ceriodaphnia dubia Daphnia pulex Daphnia magna or Pimephales promelas (Fathead minnow)

324 Water quality (DO pH conductivity hardness alkalinity and TRC) is measured at the time of test initiation At test termination temperature DO conductivity and pH are measured The final mortality and percent effected counts are recorded Temperature is maintained at 25degplusmn 1degC for Daphnia and 20deg plusmn 1degC for fathead minnows Facilities exist to perform both fish and Daphnia tests at either temperature

33 Test Results

No statistical analysis is performed on screening data

10 Summary

This document describes the procedure for the culture of Ceriodaphnia dubia Daphnia pulex Daphnia magna that are used in aquatic toxicity testing

20 Mass Stock Cultures of Ceriodaphnia dubia Daphnia pulex and Daphnia magna

21 Stock cultures are maintained in 1000 ml beakersjars with 900 mis of culture media at 20 plusmn 1deg C These cultures are maintained only as a back-up source of organisms

22 Culture media for Ceriodaphnia dubia and Daphnia pulex is moderately-hard synthetic water Culture media for Daphnia magna is hard synthetic water (see document control number 700504 Culture Waters for Aquatic Toxicity Testing)

23 Many cultures are maintained simultaneously with an informal rotation cycle New cultures are started with young produced by individual cultures These cultures are maintained for approximately 3 weeks after which they are discarded

24 Cultures are fed YCT (yeast cerophyll digested trout chowflake food) and algae (Selanastrum capricorium) on Monday Wednesday and Friday Feeding as well as culture rotation temperature and all other relevant data is recorded by species in a log book

25 Stock cultures are also fed algae and YCT These feedings are recorded in the log book

30 Individual Cultures of Ceriodaphnia dubia Daphnia pulex Daphnia magna

31 Cultures of Daphnia magna and Daphnia pulex are maintained in 100 ml plastic beakers Twenty-four (24) beakers with one organism each are kept at all times to ensure continuous availability of neonates for testing Cultures of individual Ceriodaphnia dubia are maintained in 30 ml sterile plastic medicine cups One to two cultures of approximately 100 organisms each are kept at all times

Document Control Number 7006 Page 2 of 3______________________________________________

32 Cultures are renewed three times per week Organisms are fed daily

40 Obtaining Neonates for Testing

41 Cultures of Ceriodaphnia are started by placing one neonate into a 30 ml disposable plastic cup containing approximately 20 ml of Moderately Hard Synthetic Water New Ceriodaphnia cultures are started every ten to fourteen days D magna and D putex are replaced whenever mortality occurs

42 The individual cultures are transferred to fresh media three times per week Synthetic water algae and YCT are mixed prior to pouring into culture vessel to ensure uniformity of media The old media and neonates are kept for stock cultures for several weeks and then discarded

43 To assure neonates for chronic tests are of a very similar age transfer of individual brood stock to fresh media should be made the morning of the test The cultures are then checked approximately every two hours to find an adequate number of neonates all released with an 8 hour period For acute tests individuals are either transferred less than 24 hours before a test or the young are separated from adults less than 24 hours before a test

44 Young used in chronic testing are obtained from adults who have produced at least three broods with no less than 8 neonates in their third or subsequent brood Neonates are then distributed in a blocking procedure ie neonates from the same organism are placed in one replication of each concentration

50 DAPHNIA Food

51 Digested Flake Food

511 Add 5g flake food to 1 L deionized water Mix well in a blender and place in a 2 L separatory funnel To digest aerate this mixture at room temperature for one week

DECEMBER 2003

All activities described below for this item were conducted pursuant to the Consent Decree

a Activities UndertakenCompleted

Completed semi-annual groundwater sampling and analysis including re-collection of sample from OPCA-MW-4 for analysis of dioxinsfurans (original sample damaged at laboratory)

b SamplingTest Results Received

See attached tables

Preliminary analytical results received in December 2003 from the fall 2003 GMA 4 interim groundwater quality monitoring activities are shown in Table 24-2 These preliminary results have been compared to the Method 1 GW-2 and GW-3 groundwater standards and UCLs for groundwater set forth in the MCP In these comparisons for PCBs and inorganics the filtered sample results were used for the comparisons to the Method 1 GW-3 standards (there are no GW-2 standards for these constituents) and the unfiltered sample results were used for the comparisons to UCLs These comparisons indicate the following

bull There were no exceedances of UCLs in any of the groundwater sample results received in December 2003

bull The MCP GW-2 standards were not exceeded in any of the GW-2 groundwater sample results received in December 2003

bull The MCP GW-3 standard for PCBs (00003 ppm) was slightly exceeded in the filtered sample from monitoring well OPCA-MW-8 This is the first such exceedance observed in this well No other MCP GW-3 standards were exceeded in any of the groundwater sample results received in December 2003

10 Introduction

11 Background

In 1972 amendments were made to the Clean Water Act (CWA) prohibiting the discharge of any pollutant from a point source to waters of the United States unless the discharge is authorized by a National Pollutant Discharge Elimination System (NPDES) permit Since the passing of the 1972 amendments to the CWA significant progress has been made in cleaning up industrial process wastewater and municipal sewage

The purpose of the National Pollutant Discharge Elimination System (NPDES) Program is to protect human health and the environment The Clean Water Act requires that all point sources discharging pollutants into waters of the United States must obtain an NPDES permit By point sources EPA means discrete conveyances such as pipes or man made ditches

For many years discharge limits were based on available technology for wastewater treatment However in 1984 the US Environmental Protection Agency (EPA) released a national policy statement entitled Policy for the Development of Water Quality-Based Permit Limitations for Toxic Pollutants (US EPA 1984) which addresses the control of toxic pollutants beyond technology-based requirements in order to meet water quality standards To implement the new policy guidance was provided to the respective state and regional permit personnel in the EPAs Technical Support Document for Water Quality-Based Toxics Control (US EPA 1985 US EPA 1991) The EPAs

policy statement and the support document recommended that where appropriate permit limits should be based on effluent toxicity as measured in aquatic toxicity tests

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 8SGS

12 Clean Water Act 33 USC ss 1251 et seq (1977)

The Clean Water Act is a 1977 amendment to the Federal Water Pollution Control Act of 1972 which set the basic structure for regulating discharges of pollutants to waters of the United States The law gave EPA the authority to set effluent standards on an industry basis (technology-based) and continued the requirements to set water quality standards for all contaminants in surface waters The CWA makes it unlawful for any person to discharge any pollutant from a point source into navigable waters unless a permit (NPDES) is obtained under the Act The 1977 amendments focused on toxic pollutants In 1987 the CWA was reauthorized and again focused on toxic substances authorized citizen suit provisions and funded sewage treatment plants (POTWs) under the Construction Grants Program The CWA provisions for the delegation by EPA of many permitting administrative and enforcement aspects of the law to state governments In states with the authority to implement CWA programs EPA still retains oversight responsibilities

13 Objective of the General Electric Study The objective of this study was to measure the acute toxicity of the composite wastewater discharged by the General Electric facility located in Pittsfield Massachusetts using Daphnia pufex under static conditions Whereas D pulex are not considered locally important they are routinely used by regulatory agencies and contract laboratories nationwide for toxicity testing A toxicity test was conducted from December 3 2003 to December 5 2003 at SGS Environmental Services Charleston West Virginia All original raw data and the final report produced for this study are stored in SGSs archives at the above location

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 11 SGS

25 Test Organisms

Daphnids (Daphnia pulex) less than 24-hours old were obtained from SGS

laboratory cultures maintained in Charleston The culture system consisted of twenty-four (24) 100 ml disposable plastic beakers each containing 80 ml of culture medium and one (1) daphnid The culture medium was deionized (DI) water for which the hardness was raised by addition of reagent grade chemicals (US EPA 1993) Prior to use the culture water was characterized

Parameter Result Total Hardness within range of 80-110 mgL Alkalinity (as CaCO3) within range of 60-70 mgL pH within range of 70 to 72

The culture area was maintained at a temperature of 20degC (plusmn 1degC) with a

regulated photoperiod of 16 hours of light and 8 hours of darkness

Daphnid cultures were fed a combination of green algae (Setanastrum

capricorium] approximately 40 x 107 cellsml) and YCT (yeast cereal leaves and trout chow) Approximately 10 ml of algae and 05 ml of YCT was added to each culture vessel daily Three times per week daphnids are transferred to fresh culture media

Approximately twenty-four hours before test initiation all immature daphnids were removed from the culture flasks Offspring produced during the period were used in the toxicity test

26 Test Procedures

A subsample of the effluent and the dilution water (approximately 2250 ml) was analyzed by SGS for total phosphorus chloride total suspended solids and total solids The 48-hour toxicity test was conducted at concentrations of 100 75 50 35 15 and 5 effluent Test concentrations were prepared by diluting

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 12 SGS

the appropriate volume of effluent with dilution water to a total volume of 250 ml Test solutions were then divided into replicate (5 replicates per concentration) 30 ml medicine cups each containing 20 ml of test solution One set of five control beakers (containing Housatonic River water) and one set of five reference control beakers (containing moderately hard reconstituted water) were established and maintained under the same conditions as the exposure concentrations A secondary set of five reference control beakers (containing sodium thiosulfate) was also maintained Test solutions were placed in an incubator to maintain solution temperature of 20degC (plusmn 1degC) Light was provided on a 16-hour light and 8-hour dark photoperiod Florescent bulbs provided an illumination of 90 to 100 foot-candles in the test area

Prior to test initiation daphnids less than 24-hours old were culled individually with a plastic pipette and placed into a 1000 ml holding beaker containing approximately 500 ml of reference water The test was initiated when daphnids were individually transferred from the holding beaker to the test solutions (4 daphnids per replicate) The daphnids were fed prior to test initiation but were not fed during the exposure period

27 Test Monitoring

The number of mortalities and observations in each replicate vessel were recorded at 24 and 48 hours of exposure and observed mortalities were removed from the test solutions Biological observations and observations from the physical characteristics of each replicate test solution and control were also made and recorded at 0 24 and 48 hours Dissolved oxygen concentrations pH and temperature were measured at test initiation and at 24-hour intervals thereafter in one replicate vessel (a) for each test concentration in which there were surviving organisms

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 13 SGS

Total hardness concentrations were measured by the EDTA titrimetric method and total alkalinity concentrations were determined by potentiometric titration to an endpoint of pH 45 (APHA 1989) Total residual chorine was measured by Hach test Concentrations of ammonia were determined using a Buchi model 212 distillation unit and titrated automatically with a Brinkman titroprocessor Specific conductivity was measured with a Cole Palmer Model 71250 salinityshyconductivity-temperature meter and probe pH was measured with a Fisher Scientific Accumet 910 pH meter and combination electrode dissolved oxygen concentration was measured with an YSI Model 59 dissolved oxygen meter Daily temperature measurements were performed with a Princo mercury thermometer and a Fisher minimum-maximum thermometer Light intensity was measured with a General Electric type 217 light meter

28 Reference Toxicity Test

A 48-hour reference toxicity test exposing Daphnia pulex to sodium chloride (NaCI) was conducted from December 2 2003 to December 4 2003 The reference test was conducted to establish the health of the test organisms The reference toxicity test included five NaCI concentrations and a dilution water control (moderately hard reconstituted water) The nominal NaCI concentrations for the test with Daphnia pulex ranged from 625 to 10000 mg of NaCIL Test methods were the same as those described above for the effluent test

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 14 SGS

30 Statistics

The concentration-response relationships observed were characterized by the median lethal concentrations (LC50) which is the concentration that is calculated to be lethal to 50 percent of the organisms within the test period If no concentration caused mortality of 50 then the LC50 value was determined to be greater than the highest concentration tested and no statistical analysis were performed If at least one concentration caused mortality of greater than 50 of the test population then a computer program (TOXSTAT 35) was used to calculate the LC50 value Three statistical methods were available in the computer program probit analysis the Trimmed Spearman-Karber and the Spearman-Karber methods The graphical method is available if appropriate Generally to choose the best estimate of the LC50 value for a particular data set the US EPA flow chart on page 15 was followed

The No-Observable-Acute-Effect-Level (NOAEL) was estimated for the acute toxicity test and is defined as the highest concentration of effluent that produced gt 90 survival

effluent is dechlorinated and the other is not (Dechlorination may be prohibited permit is checked to determine if dechlorination is allowed) The effluent is dechlorinated by the addition of anhydrous sodium thiosulfate The measured amount is recorded on the bench sheet Care is taken to add the least amount of sodium thiosulfate needed to decrease the TRC level below 010 mgL Typically adjustment of effluent is unnecessary

322 Twenty organisms per concentration are used in acute screening tests

323 This is a static non-renewal test using Ceriodaphnia dubia Daphnia pulex Daphnia magna or Pimephales promelas (Fathead minnow)

324 Water quality (DO pH conductivity hardness alkalinity and TRC) is measured at the time of test initiation At test termination temperature DO conductivity and pH are measured The final mortality and percent effected counts are recorded Temperature is maintained at 25degplusmn 1degC for Daphnia and 20deg plusmn 1degC for fathead minnows Facilities exist to perform both fish and Daphnia tests at either temperature

33 Test Results

No statistical analysis is performed on screening data

recorded If the pH DO or chlorine fall outside the acceptable testing range the effluent may be adjusted (see screening Test Preparation)

4133 The dilutions are prepared in calibrated graduated cylinders using moderately hard synthetic water as dilution water Other dilution water may be used if specified

4134 Approximately 400 ml of test solution is placed in each of two 800 ml disposable plastic beakers

414 Loading

Ten (10) organisms are placed in each beaker CTampE uses fish which are less than 14 days old and are hatched within the same 24 hour period A loading limit of 08 gl is observed Fish are loaded by first transferring them to a shallow dish where they are easily transferred into the test solutions with wide-bore pipettes

415 Test Temperature

20degC(plusmn1)

416 Daily Procedures

4161 At the end of each 24 hours the pH DO and temperatures are checked and recorded At this time mortalities are also recorded

4162 If a 96 hour static acute test is required the test solution may be renewed at 48 hours Renewal is accomplished by siphoning old test solution and debris and replacing with fresh solution of the appropriate concentration

4163 At the end of 48 hours or 96 hours the final mortalities and percent affected are recorded along with the final water qualities (DO pH conductivity)

417 Feeding

Organisms are allowed to feed only prior to test initiation and prior to renewal at 48 hours in a 96 hour test

10 Summary

This document describes the procedure for the culture of Ceriodaphnia dubia Daphnia pulex Daphnia magna that are used in aquatic toxicity testing

20 Mass Stock Cultures of Ceriodaphnia dubia Daphnia pulex and Daphnia magna

21 Stock cultures are maintained in 1000 ml beakersjars with 900 mis of culture media at 20 plusmn 1deg C These cultures are maintained only as a back-up source of organisms

22 Culture media for Ceriodaphnia dubia and Daphnia pulex is moderately-hard synthetic water Culture media for Daphnia magna is hard synthetic water (see document control number 700504 Culture Waters for Aquatic Toxicity Testing)

23 Many cultures are maintained simultaneously with an informal rotation cycle New cultures are started with young produced by individual cultures These cultures are maintained for approximately 3 weeks after which they are discarded

24 Cultures are fed YCT (yeast cerophyll digested trout chowflake food) and algae (Selanastrum capricorium) on Monday Wednesday and Friday Feeding as well as culture rotation temperature and all other relevant data is recorded by species in a log book

25 Stock cultures are also fed algae and YCT These feedings are recorded in the log book

30 Individual Cultures of Ceriodaphnia dubia Daphnia pulex Daphnia magna

31 Cultures of Daphnia magna and Daphnia pulex are maintained in 100 ml plastic beakers Twenty-four (24) beakers with one organism each are kept at all times to ensure continuous availability of neonates for testing Cultures of individual Ceriodaphnia dubia are maintained in 30 ml sterile plastic medicine cups One to two cultures of approximately 100 organisms each are kept at all times

Document Control Number 7006 Page 2 of 3______________________________________________

32 Cultures are renewed three times per week Organisms are fed daily

40 Obtaining Neonates for Testing

41 Cultures of Ceriodaphnia are started by placing one neonate into a 30 ml disposable plastic cup containing approximately 20 ml of Moderately Hard Synthetic Water New Ceriodaphnia cultures are started every ten to fourteen days D magna and D putex are replaced whenever mortality occurs

42 The individual cultures are transferred to fresh media three times per week Synthetic water algae and YCT are mixed prior to pouring into culture vessel to ensure uniformity of media The old media and neonates are kept for stock cultures for several weeks and then discarded

43 To assure neonates for chronic tests are of a very similar age transfer of individual brood stock to fresh media should be made the morning of the test The cultures are then checked approximately every two hours to find an adequate number of neonates all released with an 8 hour period For acute tests individuals are either transferred less than 24 hours before a test or the young are separated from adults less than 24 hours before a test

44 Young used in chronic testing are obtained from adults who have produced at least three broods with no less than 8 neonates in their third or subsequent brood Neonates are then distributed in a blocking procedure ie neonates from the same organism are placed in one replication of each concentration

50 DAPHNIA Food

51 Digested Flake Food

511 Add 5g flake food to 1 L deionized water Mix well in a blender and place in a 2 L separatory funnel To digest aerate this mixture at room temperature for one week

b SamplingTest Results Received

See attached tables

Preliminary analytical results received in December 2003 from the fall 2003 GMA 4 interim groundwater quality monitoring activities are shown in Table 24-2 These preliminary results have been compared to the Method 1 GW-2 and GW-3 groundwater standards and UCLs for groundwater set forth in the MCP In these comparisons for PCBs and inorganics the filtered sample results were used for the comparisons to the Method 1 GW-3 standards (there are no GW-2 standards for these constituents) and the unfiltered sample results were used for the comparisons to UCLs These comparisons indicate the following

bull There were no exceedances of UCLs in any of the groundwater sample results received in December 2003

bull The MCP GW-2 standards were not exceeded in any of the GW-2 groundwater sample results received in December 2003

bull The MCP GW-3 standard for PCBs (00003 ppm) was slightly exceeded in the filtered sample from monitoring well OPCA-MW-8 This is the first such exceedance observed in this well No other MCP GW-3 standards were exceeded in any of the groundwater sample results received in December 2003

10 Introduction

11 Background

In 1972 amendments were made to the Clean Water Act (CWA) prohibiting the discharge of any pollutant from a point source to waters of the United States unless the discharge is authorized by a National Pollutant Discharge Elimination System (NPDES) permit Since the passing of the 1972 amendments to the CWA significant progress has been made in cleaning up industrial process wastewater and municipal sewage

The purpose of the National Pollutant Discharge Elimination System (NPDES) Program is to protect human health and the environment The Clean Water Act requires that all point sources discharging pollutants into waters of the United States must obtain an NPDES permit By point sources EPA means discrete conveyances such as pipes or man made ditches

For many years discharge limits were based on available technology for wastewater treatment However in 1984 the US Environmental Protection Agency (EPA) released a national policy statement entitled Policy for the Development of Water Quality-Based Permit Limitations for Toxic Pollutants (US EPA 1984) which addresses the control of toxic pollutants beyond technology-based requirements in order to meet water quality standards To implement the new policy guidance was provided to the respective state and regional permit personnel in the EPAs Technical Support Document for Water Quality-Based Toxics Control (US EPA 1985 US EPA 1991) The EPAs

policy statement and the support document recommended that where appropriate permit limits should be based on effluent toxicity as measured in aquatic toxicity tests

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 8SGS

12 Clean Water Act 33 USC ss 1251 et seq (1977)

The Clean Water Act is a 1977 amendment to the Federal Water Pollution Control Act of 1972 which set the basic structure for regulating discharges of pollutants to waters of the United States The law gave EPA the authority to set effluent standards on an industry basis (technology-based) and continued the requirements to set water quality standards for all contaminants in surface waters The CWA makes it unlawful for any person to discharge any pollutant from a point source into navigable waters unless a permit (NPDES) is obtained under the Act The 1977 amendments focused on toxic pollutants In 1987 the CWA was reauthorized and again focused on toxic substances authorized citizen suit provisions and funded sewage treatment plants (POTWs) under the Construction Grants Program The CWA provisions for the delegation by EPA of many permitting administrative and enforcement aspects of the law to state governments In states with the authority to implement CWA programs EPA still retains oversight responsibilities

13 Objective of the General Electric Study The objective of this study was to measure the acute toxicity of the composite wastewater discharged by the General Electric facility located in Pittsfield Massachusetts using Daphnia pufex under static conditions Whereas D pulex are not considered locally important they are routinely used by regulatory agencies and contract laboratories nationwide for toxicity testing A toxicity test was conducted from December 3 2003 to December 5 2003 at SGS Environmental Services Charleston West Virginia All original raw data and the final report produced for this study are stored in SGSs archives at the above location

22 Effluent Sample

The effluent sample (A5288C) was collected by GE personnel from December 1 2003 to December 2 2003 Upon receipt at SGS on December 3 2003 the sample temperature was 34deg C The effluent sample was characterized as having

Parameter Result Total Hardness 290 Alkalinity (as CaCO3) 294 pH 791 Specific Conductance 965 Dissolved Oxygen Concentration 885

Dissolved oxygen concentration was recorded after sample was aerated and warmed to approximately 20degC)

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 10 SGS

The effluent sample was observed to be clear and colorless

23 Dilution Water

Dilution water consisted of receiving water collected from the Housatonic River The receiving water (A5287R) was collected by General Electric personnel on December 2 2003 Upon receipt at SGS on December 3 2003 the sample temperature was 34degC The dilution water was characterized as having

Parameter Result Total Hardness 50 Alkalinity (as CaCO3)pHSpecific ConductanceDissolved Oxygen Concentration

122 904

Dissolved oxygen concentration was recorded after sample was aerated and warmed to approximately 20degC)

The dilution water sample was observed to be slightly cloudy with a straw color

24 Reference Control Water Water used in the reference control vessels was deionized (DI) water adjusted to the appropriate hardness (moderately hard reconstituted water) by the addition

of reagent grade chemicals (US ERA 1993) Characterization of this water resulted in

Parameter Result Total Hardness 100 Alkalinity (as CaC03) 69 pH 712 Specific Conductance 324 Dissolved Oxygen 872

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 11 SGS

25 Test Organisms

Daphnids (Daphnia pulex) less than 24-hours old were obtained from SGS

laboratory cultures maintained in Charleston The culture system consisted of twenty-four (24) 100 ml disposable plastic beakers each containing 80 ml of culture medium and one (1) daphnid The culture medium was deionized (DI) water for which the hardness was raised by addition of reagent grade chemicals (US EPA 1993) Prior to use the culture water was characterized

Parameter Result Total Hardness within range of 80-110 mgL Alkalinity (as CaCO3) within range of 60-70 mgL pH within range of 70 to 72

The culture area was maintained at a temperature of 20degC (plusmn 1degC) with a

regulated photoperiod of 16 hours of light and 8 hours of darkness

Daphnid cultures were fed a combination of green algae (Setanastrum

capricorium] approximately 40 x 107 cellsml) and YCT (yeast cereal leaves and trout chow) Approximately 10 ml of algae and 05 ml of YCT was added to each culture vessel daily Three times per week daphnids are transferred to fresh culture media

Approximately twenty-four hours before test initiation all immature daphnids were removed from the culture flasks Offspring produced during the period were used in the toxicity test

26 Test Procedures

A subsample of the effluent and the dilution water (approximately 2250 ml) was analyzed by SGS for total phosphorus chloride total suspended solids and total solids The 48-hour toxicity test was conducted at concentrations of 100 75 50 35 15 and 5 effluent Test concentrations were prepared by diluting

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 12 SGS

the appropriate volume of effluent with dilution water to a total volume of 250 ml Test solutions were then divided into replicate (5 replicates per concentration) 30 ml medicine cups each containing 20 ml of test solution One set of five control beakers (containing Housatonic River water) and one set of five reference control beakers (containing moderately hard reconstituted water) were established and maintained under the same conditions as the exposure concentrations A secondary set of five reference control beakers (containing sodium thiosulfate) was also maintained Test solutions were placed in an incubator to maintain solution temperature of 20degC (plusmn 1degC) Light was provided on a 16-hour light and 8-hour dark photoperiod Florescent bulbs provided an illumination of 90 to 100 foot-candles in the test area

Prior to test initiation daphnids less than 24-hours old were culled individually with a plastic pipette and placed into a 1000 ml holding beaker containing approximately 500 ml of reference water The test was initiated when daphnids were individually transferred from the holding beaker to the test solutions (4 daphnids per replicate) The daphnids were fed prior to test initiation but were not fed during the exposure period

27 Test Monitoring

The number of mortalities and observations in each replicate vessel were recorded at 24 and 48 hours of exposure and observed mortalities were removed from the test solutions Biological observations and observations from the physical characteristics of each replicate test solution and control were also made and recorded at 0 24 and 48 hours Dissolved oxygen concentrations pH and temperature were measured at test initiation and at 24-hour intervals thereafter in one replicate vessel (a) for each test concentration in which there were surviving organisms

Total hardness concentrations were measured by the EDTA titrimetric method and total alkalinity concentrations were determined by potentiometric titration to an endpoint of pH 45 (APHA 1989) Total residual chorine was measured by Hach test Concentrations of ammonia were determined using a Buchi model 212 distillation unit and titrated automatically with a Brinkman titroprocessor Specific conductivity was measured with a Cole Palmer Model 71250 salinityshyconductivity-temperature meter and probe pH was measured with a Fisher Scientific Accumet 910 pH meter and combination electrode dissolved oxygen concentration was measured with an YSI Model 59 dissolved oxygen meter Daily temperature measurements were performed with a Princo mercury thermometer and a Fisher minimum-maximum thermometer Light intensity was measured with a General Electric type 217 light meter

28 Reference Toxicity Test

A 48-hour reference toxicity test exposing Daphnia pulex to sodium chloride (NaCI) was conducted from December 2 2003 to December 4 2003 The reference test was conducted to establish the health of the test organisms The reference toxicity test included five NaCI concentrations and a dilution water control (moderately hard reconstituted water) The nominal NaCI concentrations for the test with Daphnia pulex ranged from 625 to 10000 mg of NaCIL Test methods were the same as those described above for the effluent test

30 Statistics

The concentration-response relationships observed were characterized by the median lethal concentrations (LC50) which is the concentration that is calculated to be lethal to 50 percent of the organisms within the test period If no concentration caused mortality of 50 then the LC50 value was determined to be greater than the highest concentration tested and no statistical analysis were performed If at least one concentration caused mortality of greater than 50 of the test population then a computer program (TOXSTAT 35) was used to calculate the LC50 value Three statistical methods were available in the computer program probit analysis the Trimmed Spearman-Karber and the Spearman-Karber methods The graphical method is available if appropriate Generally to choose the best estimate of the LC50 value for a particular data set the US EPA flow chart on page 15 was followed

The No-Observable-Acute-Effect-Level (NOAEL) was estimated for the acute toxicity test and is defined as the highest concentration of effluent that produced gt 90 survival

effluent is dechlorinated and the other is not (Dechlorination may be prohibited permit is checked to determine if dechlorination is allowed) The effluent is dechlorinated by the addition of anhydrous sodium thiosulfate The measured amount is recorded on the bench sheet Care is taken to add the least amount of sodium thiosulfate needed to decrease the TRC level below 010 mgL Typically adjustment of effluent is unnecessary

322 Twenty organisms per concentration are used in acute screening tests

323 This is a static non-renewal test using Ceriodaphnia dubia Daphnia pulex Daphnia magna or Pimephales promelas (Fathead minnow)

324 Water quality (DO pH conductivity hardness alkalinity and TRC) is measured at the time of test initiation At test termination temperature DO conductivity and pH are measured The final mortality and percent effected counts are recorded Temperature is maintained at 25degplusmn 1degC for Daphnia and 20deg plusmn 1degC for fathead minnows Facilities exist to perform both fish and Daphnia tests at either temperature

33 Test Results

No statistical analysis is performed on screening data

10 Summary

This document describes the procedure for the culture of Ceriodaphnia dubia Daphnia pulex Daphnia magna that are used in aquatic toxicity testing

20 Mass Stock Cultures of Ceriodaphnia dubia Daphnia pulex and Daphnia magna

21 Stock cultures are maintained in 1000 ml beakersjars with 900 mis of culture media at 20 plusmn 1deg C These cultures are maintained only as a back-up source of organisms

22 Culture media for Ceriodaphnia dubia and Daphnia pulex is moderately-hard synthetic water Culture media for Daphnia magna is hard synthetic water (see document control number 700504 Culture Waters for Aquatic Toxicity Testing)

23 Many cultures are maintained simultaneously with an informal rotation cycle New cultures are started with young produced by individual cultures These cultures are maintained for approximately 3 weeks after which they are discarded

24 Cultures are fed YCT (yeast cerophyll digested trout chowflake food) and algae (Selanastrum capricorium) on Monday Wednesday and Friday Feeding as well as culture rotation temperature and all other relevant data is recorded by species in a log book

25 Stock cultures are also fed algae and YCT These feedings are recorded in the log book

30 Individual Cultures of Ceriodaphnia dubia Daphnia pulex Daphnia magna

31 Cultures of Daphnia magna and Daphnia pulex are maintained in 100 ml plastic beakers Twenty-four (24) beakers with one organism each are kept at all times to ensure continuous availability of neonates for testing Cultures of individual Ceriodaphnia dubia are maintained in 30 ml sterile plastic medicine cups One to two cultures of approximately 100 organisms each are kept at all times

Document Control Number 7006 Page 2 of 3______________________________________________

32 Cultures are renewed three times per week Organisms are fed daily

40 Obtaining Neonates for Testing

41 Cultures of Ceriodaphnia are started by placing one neonate into a 30 ml disposable plastic cup containing approximately 20 ml of Moderately Hard Synthetic Water New Ceriodaphnia cultures are started every ten to fourteen days D magna and D putex are replaced whenever mortality occurs

42 The individual cultures are transferred to fresh media three times per week Synthetic water algae and YCT are mixed prior to pouring into culture vessel to ensure uniformity of media The old media and neonates are kept for stock cultures for several weeks and then discarded

43 To assure neonates for chronic tests are of a very similar age transfer of individual brood stock to fresh media should be made the morning of the test The cultures are then checked approximately every two hours to find an adequate number of neonates all released with an 8 hour period For acute tests individuals are either transferred less than 24 hours before a test or the young are separated from adults less than 24 hours before a test

44 Young used in chronic testing are obtained from adults who have produced at least three broods with no less than 8 neonates in their third or subsequent brood Neonates are then distributed in a blocking procedure ie neonates from the same organism are placed in one replication of each concentration

24 Ten organisms are placed in each replicate Fish are loaded by first siphoning them into a shallow pan from which they are transferred to the beakers with a large bore pipette

25 The test is terminated at 48 hours At this time mortalities are recorded along with final water quality data

30 Daphnids (Ceriodaphnia dubia Daphnia magna Daphnia pulex)

31 48 hour static acute tests are performed at 25degC (plusmn1degC) using organisms less than 24 hours old

32 These tests consist of a control and a five dilution series The concentration of the reference toxicant is varied depending on species

10 Summary

This document describes the manner in which sample waters (effluents wastewaters etc) are handled from point of collection to testing

20 Sample Handling

21 Sampling Personnel

CTampEs sampling personnel are trained and experienced in the techniques for collecting samples according to NPDES permit requirements This includes the use of automatic sampling equipment and the measurement of various field parameters

22 Sample Containers

Sample containers used by CTampE are disposable plastic cubitainersreg

23 Sample Collection Points

For NPDES permit required tests the sample will be collected at the point specified in the discharge permit unless otherwise directed by the regulatory agency

24 Sample Shipment

Samples are placed on ice (sufficient to maintain 0-4degC) in a cooler and are transported as quickly as possible to the laboratory

25 Laboratory Handling of Samples

Upon delivery to the laboratory the effluent samples are inspected given a sample control number and stored at 4deg C until used for testing

Document Control Number 7009 Page 2 of 3______________________________________________

26 Sample Holding Time

Samples will be tested within 24 hours upon receipt in the laboratory The maximum lapsed time for collection of a grab or composite sample and the initiation of lest or for test solution renewal will not exceed 36-hours for Chronic and Acute Testing

30 LABORATORY ENVIRONMENT

31 Laboratory Arrangement

The aquatic toxicity testing laboratory is divided into two separate areas (1) the culturing laboratory and (2) the testing laboratory See attached diagram for details of laboratory layout

32 Temperature

The aquatic toxicity testing laboratory air temperature is maintained at 20 plusmn 1deg C throughout the year by a central heating and cooling system which is regulated by thermostats Temperatures are continuously recorded by thermographs

33 Water

Several waters are available for use in the laboratory CTampE has access to municipally supplied water well water and reagent water from which synthetic water is prepared Waters used for culturing and testing are analyzed semiannually for priority pollutants and other contaminants A detailed report is available

34 Lighting

Ambient laboratory lighting is regulated with a 16 hour day8 hour night photoperiod controlled by an electronic timing system in the culturing and testing areas

40 LABORATORY EQUIPMENT

41 General

Instruments used for the measurement of physical and chemical parameters are calibrated prior to use in testing Any instrument that exceeds the calibration limits is taken out of service and corrective action is taken

42 Balances

Analytical balances are calibrated against standard weights prior to use All calibration results and adjustments are recorded in bound books

43 Water Quality Meters

Meters are calibrated prior to use using known standards and the manufacturers instructions Records of calibration are kept in logbooks Detailed procedures for the operation of these meters are found in SOPs for each specific instrument

44 Reagents

All reagents are stored in a separate area Expired reagents and chemicals are discarded

45 Test Containers

All test containers are either clean reusable glassware or new disposable plastic beakers

50 EQUIPMENT CLEANING PROCEDURES

51 Equipment used in culturing or testing is washed in the following manner

511 Soak 15 minutes and scrub with detergent in tap water 512 Rinse three times with tap water 513 Rinse once with 20 nitric acid 514 Rinse twice with deionized water 515 Rinse once with full-strength pesticide-grade acetone 516 Rinse well with deionized water 517 Invert and air dry 518 All equipment and test chambers are rinsed with deionized water

immediately prior to use for each test

DECEMBER 2003

All activities described below for this item were conducted pursuant to the Consent Decree

a Activities UndertakenCompleted

Completed semi-annual groundwater sampling and analysis including re-collection of sample from OPCA-MW-4 for analysis of dioxinsfurans (original sample damaged at laboratory)

b SamplingTest Results Received

See attached tables

Preliminary analytical results received in December 2003 from the fall 2003 GMA 4 interim groundwater quality monitoring activities are shown in Table 24-2 These preliminary results have been compared to the Method 1 GW-2 and GW-3 groundwater standards and UCLs for groundwater set forth in the MCP In these comparisons for PCBs and inorganics the filtered sample results were used for the comparisons to the Method 1 GW-3 standards (there are no GW-2 standards for these constituents) and the unfiltered sample results were used for the comparisons to UCLs These comparisons indicate the following

bull There were no exceedances of UCLs in any of the groundwater sample results received in December 2003

bull The MCP GW-2 standards were not exceeded in any of the GW-2 groundwater sample results received in December 2003

bull The MCP GW-3 standard for PCBs (00003 ppm) was slightly exceeded in the filtered sample from monitoring well OPCA-MW-8 This is the first such exceedance observed in this well No other MCP GW-3 standards were exceeded in any of the groundwater sample results received in December 2003

10 Introduction

11 Background

In 1972 amendments were made to the Clean Water Act (CWA) prohibiting the discharge of any pollutant from a point source to waters of the United States unless the discharge is authorized by a National Pollutant Discharge Elimination System (NPDES) permit Since the passing of the 1972 amendments to the CWA significant progress has been made in cleaning up industrial process wastewater and municipal sewage

The purpose of the National Pollutant Discharge Elimination System (NPDES) Program is to protect human health and the environment The Clean Water Act requires that all point sources discharging pollutants into waters of the United States must obtain an NPDES permit By point sources EPA means discrete conveyances such as pipes or man made ditches

For many years discharge limits were based on available technology for wastewater treatment However in 1984 the US Environmental Protection Agency (EPA) released a national policy statement entitled Policy for the Development of Water Quality-Based Permit Limitations for Toxic Pollutants (US EPA 1984) which addresses the control of toxic pollutants beyond technology-based requirements in order to meet water quality standards To implement the new policy guidance was provided to the respective state and regional permit personnel in the EPAs Technical Support Document for Water Quality-Based Toxics Control (US EPA 1985 US EPA 1991) The EPAs

policy statement and the support document recommended that where appropriate permit limits should be based on effluent toxicity as measured in aquatic toxicity tests

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 8SGS

12 Clean Water Act 33 USC ss 1251 et seq (1977)

The Clean Water Act is a 1977 amendment to the Federal Water Pollution Control Act of 1972 which set the basic structure for regulating discharges of pollutants to waters of the United States The law gave EPA the authority to set effluent standards on an industry basis (technology-based) and continued the requirements to set water quality standards for all contaminants in surface waters The CWA makes it unlawful for any person to discharge any pollutant from a point source into navigable waters unless a permit (NPDES) is obtained under the Act The 1977 amendments focused on toxic pollutants In 1987 the CWA was reauthorized and again focused on toxic substances authorized citizen suit provisions and funded sewage treatment plants (POTWs) under the Construction Grants Program The CWA provisions for the delegation by EPA of many permitting administrative and enforcement aspects of the law to state governments In states with the authority to implement CWA programs EPA still retains oversight responsibilities

13 Objective of the General Electric Study The objective of this study was to measure the acute toxicity of the composite wastewater discharged by the General Electric facility located in Pittsfield Massachusetts using Daphnia pufex under static conditions Whereas D pulex are not considered locally important they are routinely used by regulatory agencies and contract laboratories nationwide for toxicity testing A toxicity test was conducted from December 3 2003 to December 5 2003 at SGS Environmental Services Charleston West Virginia All original raw data and the final report produced for this study are stored in SGSs archives at the above location

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 11 SGS

25 Test Organisms

Daphnids (Daphnia pulex) less than 24-hours old were obtained from SGS

laboratory cultures maintained in Charleston The culture system consisted of twenty-four (24) 100 ml disposable plastic beakers each containing 80 ml of culture medium and one (1) daphnid The culture medium was deionized (DI) water for which the hardness was raised by addition of reagent grade chemicals (US EPA 1993) Prior to use the culture water was characterized

Parameter Result Total Hardness within range of 80-110 mgL Alkalinity (as CaCO3) within range of 60-70 mgL pH within range of 70 to 72

The culture area was maintained at a temperature of 20degC (plusmn 1degC) with a

regulated photoperiod of 16 hours of light and 8 hours of darkness

Daphnid cultures were fed a combination of green algae (Setanastrum

capricorium] approximately 40 x 107 cellsml) and YCT (yeast cereal leaves and trout chow) Approximately 10 ml of algae and 05 ml of YCT was added to each culture vessel daily Three times per week daphnids are transferred to fresh culture media

Approximately twenty-four hours before test initiation all immature daphnids were removed from the culture flasks Offspring produced during the period were used in the toxicity test

26 Test Procedures

A subsample of the effluent and the dilution water (approximately 2250 ml) was analyzed by SGS for total phosphorus chloride total suspended solids and total solids The 48-hour toxicity test was conducted at concentrations of 100 75 50 35 15 and 5 effluent Test concentrations were prepared by diluting

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 12 SGS

the appropriate volume of effluent with dilution water to a total volume of 250 ml Test solutions were then divided into replicate (5 replicates per concentration) 30 ml medicine cups each containing 20 ml of test solution One set of five control beakers (containing Housatonic River water) and one set of five reference control beakers (containing moderately hard reconstituted water) were established and maintained under the same conditions as the exposure concentrations A secondary set of five reference control beakers (containing sodium thiosulfate) was also maintained Test solutions were placed in an incubator to maintain solution temperature of 20degC (plusmn 1degC) Light was provided on a 16-hour light and 8-hour dark photoperiod Florescent bulbs provided an illumination of 90 to 100 foot-candles in the test area

Prior to test initiation daphnids less than 24-hours old were culled individually with a plastic pipette and placed into a 1000 ml holding beaker containing approximately 500 ml of reference water The test was initiated when daphnids were individually transferred from the holding beaker to the test solutions (4 daphnids per replicate) The daphnids were fed prior to test initiation but were not fed during the exposure period

27 Test Monitoring

The number of mortalities and observations in each replicate vessel were recorded at 24 and 48 hours of exposure and observed mortalities were removed from the test solutions Biological observations and observations from the physical characteristics of each replicate test solution and control were also made and recorded at 0 24 and 48 hours Dissolved oxygen concentrations pH and temperature were measured at test initiation and at 24-hour intervals thereafter in one replicate vessel (a) for each test concentration in which there were surviving organisms

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 13 SGS

Total hardness concentrations were measured by the EDTA titrimetric method and total alkalinity concentrations were determined by potentiometric titration to an endpoint of pH 45 (APHA 1989) Total residual chorine was measured by Hach test Concentrations of ammonia were determined using a Buchi model 212 distillation unit and titrated automatically with a Brinkman titroprocessor Specific conductivity was measured with a Cole Palmer Model 71250 salinityshyconductivity-temperature meter and probe pH was measured with a Fisher Scientific Accumet 910 pH meter and combination electrode dissolved oxygen concentration was measured with an YSI Model 59 dissolved oxygen meter Daily temperature measurements were performed with a Princo mercury thermometer and a Fisher minimum-maximum thermometer Light intensity was measured with a General Electric type 217 light meter

28 Reference Toxicity Test

A 48-hour reference toxicity test exposing Daphnia pulex to sodium chloride (NaCI) was conducted from December 2 2003 to December 4 2003 The reference test was conducted to establish the health of the test organisms The reference toxicity test included five NaCI concentrations and a dilution water control (moderately hard reconstituted water) The nominal NaCI concentrations for the test with Daphnia pulex ranged from 625 to 10000 mg of NaCIL Test methods were the same as those described above for the effluent test

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 14 SGS

30 Statistics

The concentration-response relationships observed were characterized by the median lethal concentrations (LC50) which is the concentration that is calculated to be lethal to 50 percent of the organisms within the test period If no concentration caused mortality of 50 then the LC50 value was determined to be greater than the highest concentration tested and no statistical analysis were performed If at least one concentration caused mortality of greater than 50 of the test population then a computer program (TOXSTAT 35) was used to calculate the LC50 value Three statistical methods were available in the computer program probit analysis the Trimmed Spearman-Karber and the Spearman-Karber methods The graphical method is available if appropriate Generally to choose the best estimate of the LC50 value for a particular data set the US EPA flow chart on page 15 was followed

The No-Observable-Acute-Effect-Level (NOAEL) was estimated for the acute toxicity test and is defined as the highest concentration of effluent that produced gt 90 survival

effluent is dechlorinated and the other is not (Dechlorination may be prohibited permit is checked to determine if dechlorination is allowed) The effluent is dechlorinated by the addition of anhydrous sodium thiosulfate The measured amount is recorded on the bench sheet Care is taken to add the least amount of sodium thiosulfate needed to decrease the TRC level below 010 mgL Typically adjustment of effluent is unnecessary

322 Twenty organisms per concentration are used in acute screening tests

323 This is a static non-renewal test using Ceriodaphnia dubia Daphnia pulex Daphnia magna or Pimephales promelas (Fathead minnow)

324 Water quality (DO pH conductivity hardness alkalinity and TRC) is measured at the time of test initiation At test termination temperature DO conductivity and pH are measured The final mortality and percent effected counts are recorded Temperature is maintained at 25degplusmn 1degC for Daphnia and 20deg plusmn 1degC for fathead minnows Facilities exist to perform both fish and Daphnia tests at either temperature

33 Test Results

No statistical analysis is performed on screening data

recorded If the pH DO or chlorine fall outside the acceptable testing range the effluent may be adjusted (see screening Test Preparation)

4133 The dilutions are prepared in calibrated graduated cylinders using moderately hard synthetic water as dilution water Other dilution water may be used if specified

4134 Approximately 400 ml of test solution is placed in each of two 800 ml disposable plastic beakers

414 Loading

Ten (10) organisms are placed in each beaker CTampE uses fish which are less than 14 days old and are hatched within the same 24 hour period A loading limit of 08 gl is observed Fish are loaded by first transferring them to a shallow dish where they are easily transferred into the test solutions with wide-bore pipettes

415 Test Temperature

20degC(plusmn1)

416 Daily Procedures

4161 At the end of each 24 hours the pH DO and temperatures are checked and recorded At this time mortalities are also recorded

4162 If a 96 hour static acute test is required the test solution may be renewed at 48 hours Renewal is accomplished by siphoning old test solution and debris and replacing with fresh solution of the appropriate concentration

4163 At the end of 48 hours or 96 hours the final mortalities and percent affected are recorded along with the final water qualities (DO pH conductivity)

417 Feeding

Organisms are allowed to feed only prior to test initiation and prior to renewal at 48 hours in a 96 hour test

10 Summary

This document describes the procedure for the culture of Ceriodaphnia dubia Daphnia pulex Daphnia magna that are used in aquatic toxicity testing

20 Mass Stock Cultures of Ceriodaphnia dubia Daphnia pulex and Daphnia magna

21 Stock cultures are maintained in 1000 ml beakersjars with 900 mis of culture media at 20 plusmn 1deg C These cultures are maintained only as a back-up source of organisms

22 Culture media for Ceriodaphnia dubia and Daphnia pulex is moderately-hard synthetic water Culture media for Daphnia magna is hard synthetic water (see document control number 700504 Culture Waters for Aquatic Toxicity Testing)

23 Many cultures are maintained simultaneously with an informal rotation cycle New cultures are started with young produced by individual cultures These cultures are maintained for approximately 3 weeks after which they are discarded

24 Cultures are fed YCT (yeast cerophyll digested trout chowflake food) and algae (Selanastrum capricorium) on Monday Wednesday and Friday Feeding as well as culture rotation temperature and all other relevant data is recorded by species in a log book

25 Stock cultures are also fed algae and YCT These feedings are recorded in the log book

30 Individual Cultures of Ceriodaphnia dubia Daphnia pulex Daphnia magna

31 Cultures of Daphnia magna and Daphnia pulex are maintained in 100 ml plastic beakers Twenty-four (24) beakers with one organism each are kept at all times to ensure continuous availability of neonates for testing Cultures of individual Ceriodaphnia dubia are maintained in 30 ml sterile plastic medicine cups One to two cultures of approximately 100 organisms each are kept at all times

Document Control Number 7006 Page 2 of 3______________________________________________

32 Cultures are renewed three times per week Organisms are fed daily

40 Obtaining Neonates for Testing

41 Cultures of Ceriodaphnia are started by placing one neonate into a 30 ml disposable plastic cup containing approximately 20 ml of Moderately Hard Synthetic Water New Ceriodaphnia cultures are started every ten to fourteen days D magna and D putex are replaced whenever mortality occurs

42 The individual cultures are transferred to fresh media three times per week Synthetic water algae and YCT are mixed prior to pouring into culture vessel to ensure uniformity of media The old media and neonates are kept for stock cultures for several weeks and then discarded

43 To assure neonates for chronic tests are of a very similar age transfer of individual brood stock to fresh media should be made the morning of the test The cultures are then checked approximately every two hours to find an adequate number of neonates all released with an 8 hour period For acute tests individuals are either transferred less than 24 hours before a test or the young are separated from adults less than 24 hours before a test

44 Young used in chronic testing are obtained from adults who have produced at least three broods with no less than 8 neonates in their third or subsequent brood Neonates are then distributed in a blocking procedure ie neonates from the same organism are placed in one replication of each concentration

50 DAPHNIA Food

51 Digested Flake Food

511 Add 5g flake food to 1 L deionized water Mix well in a blender and place in a 2 L separatory funnel To digest aerate this mixture at room temperature for one week

Completed semi-annual groundwater sampling and analysis including re-collection of sample from OPCA-MW-4 for analysis of dioxinsfurans (original sample damaged at laboratory)

b SamplingTest Results Received

See attached tables

Preliminary analytical results received in December 2003 from the fall 2003 GMA 4 interim groundwater quality monitoring activities are shown in Table 24-2 These preliminary results have been compared to the Method 1 GW-2 and GW-3 groundwater standards and UCLs for groundwater set forth in the MCP In these comparisons for PCBs and inorganics the filtered sample results were used for the comparisons to the Method 1 GW-3 standards (there are no GW-2 standards for these constituents) and the unfiltered sample results were used for the comparisons to UCLs These comparisons indicate the following

bull There were no exceedances of UCLs in any of the groundwater sample results received in December 2003

bull The MCP GW-2 standards were not exceeded in any of the GW-2 groundwater sample results received in December 2003

bull The MCP GW-3 standard for PCBs (00003 ppm) was slightly exceeded in the filtered sample from monitoring well OPCA-MW-8 This is the first such exceedance observed in this well No other MCP GW-3 standards were exceeded in any of the groundwater sample results received in December 2003

10 Introduction

11 Background

In 1972 amendments were made to the Clean Water Act (CWA) prohibiting the discharge of any pollutant from a point source to waters of the United States unless the discharge is authorized by a National Pollutant Discharge Elimination System (NPDES) permit Since the passing of the 1972 amendments to the CWA significant progress has been made in cleaning up industrial process wastewater and municipal sewage

The purpose of the National Pollutant Discharge Elimination System (NPDES) Program is to protect human health and the environment The Clean Water Act requires that all point sources discharging pollutants into waters of the United States must obtain an NPDES permit By point sources EPA means discrete conveyances such as pipes or man made ditches

For many years discharge limits were based on available technology for wastewater treatment However in 1984 the US Environmental Protection Agency (EPA) released a national policy statement entitled Policy for the Development of Water Quality-Based Permit Limitations for Toxic Pollutants (US EPA 1984) which addresses the control of toxic pollutants beyond technology-based requirements in order to meet water quality standards To implement the new policy guidance was provided to the respective state and regional permit personnel in the EPAs Technical Support Document for Water Quality-Based Toxics Control (US EPA 1985 US EPA 1991) The EPAs

policy statement and the support document recommended that where appropriate permit limits should be based on effluent toxicity as measured in aquatic toxicity tests

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 8SGS

12 Clean Water Act 33 USC ss 1251 et seq (1977)

The Clean Water Act is a 1977 amendment to the Federal Water Pollution Control Act of 1972 which set the basic structure for regulating discharges of pollutants to waters of the United States The law gave EPA the authority to set effluent standards on an industry basis (technology-based) and continued the requirements to set water quality standards for all contaminants in surface waters The CWA makes it unlawful for any person to discharge any pollutant from a point source into navigable waters unless a permit (NPDES) is obtained under the Act The 1977 amendments focused on toxic pollutants In 1987 the CWA was reauthorized and again focused on toxic substances authorized citizen suit provisions and funded sewage treatment plants (POTWs) under the Construction Grants Program The CWA provisions for the delegation by EPA of many permitting administrative and enforcement aspects of the law to state governments In states with the authority to implement CWA programs EPA still retains oversight responsibilities

13 Objective of the General Electric Study The objective of this study was to measure the acute toxicity of the composite wastewater discharged by the General Electric facility located in Pittsfield Massachusetts using Daphnia pufex under static conditions Whereas D pulex are not considered locally important they are routinely used by regulatory agencies and contract laboratories nationwide for toxicity testing A toxicity test was conducted from December 3 2003 to December 5 2003 at SGS Environmental Services Charleston West Virginia All original raw data and the final report produced for this study are stored in SGSs archives at the above location

Dissolved oxygen concentration was recorded after sample was aerated and warmed to approximately 20degC)

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 10 SGS

The effluent sample was observed to be clear and colorless

23 Dilution Water

Dilution water consisted of receiving water collected from the Housatonic River The receiving water (A5287R) was collected by General Electric personnel on December 2 2003 Upon receipt at SGS on December 3 2003 the sample temperature was 34degC The dilution water was characterized as having

Dissolved oxygen concentration was recorded after sample was aerated and warmed to approximately 20degC)

The dilution water sample was observed to be slightly cloudy with a straw color

24 Reference Control Water Water used in the reference control vessels was deionized (DI) water adjusted to the appropriate hardness (moderately hard reconstituted water) by the addition

of reagent grade chemicals (US ERA 1993) Characterization of this water resulted in

Parameter Result Total Hardness 100 Alkalinity (as CaC03) 69 pH 712 Specific Conductance 324 Dissolved Oxygen 872

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 11 SGS

25 Test Organisms

Daphnids (Daphnia pulex) less than 24-hours old were obtained from SGS

laboratory cultures maintained in Charleston The culture system consisted of twenty-four (24) 100 ml disposable plastic beakers each containing 80 ml of culture medium and one (1) daphnid The culture medium was deionized (DI) water for which the hardness was raised by addition of reagent grade chemicals (US EPA 1993) Prior to use the culture water was characterized

Parameter Result Total Hardness within range of 80-110 mgL Alkalinity (as CaCO3) within range of 60-70 mgL pH within range of 70 to 72

The culture area was maintained at a temperature of 20degC (plusmn 1degC) with a

regulated photoperiod of 16 hours of light and 8 hours of darkness

Daphnid cultures were fed a combination of green algae (Setanastrum

capricorium] approximately 40 x 107 cellsml) and YCT (yeast cereal leaves and trout chow) Approximately 10 ml of algae and 05 ml of YCT was added to each culture vessel daily Three times per week daphnids are transferred to fresh culture media

Approximately twenty-four hours before test initiation all immature daphnids were removed from the culture flasks Offspring produced during the period were used in the toxicity test

26 Test Procedures

A subsample of the effluent and the dilution water (approximately 2250 ml) was analyzed by SGS for total phosphorus chloride total suspended solids and total solids The 48-hour toxicity test was conducted at concentrations of 100 75 50 35 15 and 5 effluent Test concentrations were prepared by diluting

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 12 SGS

the appropriate volume of effluent with dilution water to a total volume of 250 ml Test solutions were then divided into replicate (5 replicates per concentration) 30 ml medicine cups each containing 20 ml of test solution One set of five control beakers (containing Housatonic River water) and one set of five reference control beakers (containing moderately hard reconstituted water) were established and maintained under the same conditions as the exposure concentrations A secondary set of five reference control beakers (containing sodium thiosulfate) was also maintained Test solutions were placed in an incubator to maintain solution temperature of 20degC (plusmn 1degC) Light was provided on a 16-hour light and 8-hour dark photoperiod Florescent bulbs provided an illumination of 90 to 100 foot-candles in the test area

Prior to test initiation daphnids less than 24-hours old were culled individually with a plastic pipette and placed into a 1000 ml holding beaker containing approximately 500 ml of reference water The test was initiated when daphnids were individually transferred from the holding beaker to the test solutions (4 daphnids per replicate) The daphnids were fed prior to test initiation but were not fed during the exposure period

27 Test Monitoring

The number of mortalities and observations in each replicate vessel were recorded at 24 and 48 hours of exposure and observed mortalities were removed from the test solutions Biological observations and observations from the physical characteristics of each replicate test solution and control were also made and recorded at 0 24 and 48 hours Dissolved oxygen concentrations pH and temperature were measured at test initiation and at 24-hour intervals thereafter in one replicate vessel (a) for each test concentration in which there were surviving organisms

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 13 SGS

Total hardness concentrations were measured by the EDTA titrimetric method and total alkalinity concentrations were determined by potentiometric titration to an endpoint of pH 45 (APHA 1989) Total residual chorine was measured by Hach test Concentrations of ammonia were determined using a Buchi model 212 distillation unit and titrated automatically with a Brinkman titroprocessor Specific conductivity was measured with a Cole Palmer Model 71250 salinityshyconductivity-temperature meter and probe pH was measured with a Fisher Scientific Accumet 910 pH meter and combination electrode dissolved oxygen concentration was measured with an YSI Model 59 dissolved oxygen meter Daily temperature measurements were performed with a Princo mercury thermometer and a Fisher minimum-maximum thermometer Light intensity was measured with a General Electric type 217 light meter

28 Reference Toxicity Test

A 48-hour reference toxicity test exposing Daphnia pulex to sodium chloride (NaCI) was conducted from December 2 2003 to December 4 2003 The reference test was conducted to establish the health of the test organisms The reference toxicity test included five NaCI concentrations and a dilution water control (moderately hard reconstituted water) The nominal NaCI concentrations for the test with Daphnia pulex ranged from 625 to 10000 mg of NaCIL Test methods were the same as those described above for the effluent test

NPDES Permit No MAOOO 3891 SGS ID number TA3-LO-P037 December 16 2003 Page 14 SGS

30 Statistics

The concentration-response relationships observed were characterized by the median lethal concentrations (LC50) which is the concentration that is calculated to be lethal to 50 percent of the organisms within the test period If no concentration caused mortality of 50 then the LC50 value was determined to be greater than the highest concentration tested and no statistical analysis were performed If at least one concentration caused mortality of greater than 50 of the test population then a computer program (TOXSTAT 35) was used to calculate the LC50 value Three statistical methods were available in the computer program probit analysis the Trimmed Spearman-Karber and the Spearman-Karber methods The graphical method is available if appropriate Generally to choose the best estimate of the LC50 value for a particular data set the US EPA flow chart on page 15 was followed

The No-Observable-Acute-Effect-Level (NOAEL) was estimated for the acute toxicity test and is defined as the highest concentration of effluent that produced gt 90 survival

effluent is dechlorinated and the other is not (Dechlorination may be prohibited permit is checked to determine if dechlorination is allowed) The effluent is dechlorinated by the addition of anhydrous sodium thiosulfate The measured amount is recorded on the bench sheet Care is taken to add the least amount of sodium thiosulfate needed to decrease the TRC level below 010 mgL Typically adjustment of effluent is unnecessary

322 Twenty organisms per concentration are used in acute screening tests

323 This is a static non-renewal test using Ceriodaphnia dubia Daphnia pulex Daphnia magna or Pimephales promelas (Fathead minnow)

324 Water quality (DO pH conductivity hardness alkalinity and TRC) is measured at the time of test initiation At test termination temperature DO conductivity and pH are measured The final mortality and percent effected counts are recorded Temperature is maintained at 25degplusmn 1degC for Daphnia and 20deg plusmn 1degC for fathead minnows Facilities exist to perform both fish and Daphnia tests at either temperature

33 Test Results

No statistical analysis is performed on screening data

10 Summary

This document describes the procedure for the culture of Ceriodaphnia dubia Daphnia pulex Daphnia magna that are used in aquatic toxicity testing

20 Mass Stock Cultures of Ceriodaphnia dubia Daphnia pulex and Daphnia magna

21 Stock cultures are maintained in 1000 ml beakersjars with 900 mis of culture media at 20 plusmn 1deg C These cultures are maintained only as a back-up source of organisms

22 Culture media for Ceriodaphnia dubia and Daphnia pulex is moderately-hard synthetic water Culture media for Daphnia magna is hard synthetic water (see document control number 700504 Culture Waters for Aquatic Toxicity Testing)

23 Many cultures are maintained simultaneously with an informal rotation cycle New cultures are started with young produced by individual cultures These cultures are maintained for approximately 3 weeks after which they are discarded

24 Cultures are fed YCT (yeast cerophyll digested trout chowflake food) and algae (Selanastrum capricorium) on Monday Wednesday and Friday Feeding as well as culture rotation temperature and all other relevant data is recorded by species in a log book

25 Stock cultures are also fed algae and YCT These feedings are recorded in the log book

30 Individual Cultures of Ceriodaphnia dubia Daphnia pulex Daphnia magna

31 Cultures of Daphnia magna and Daphnia pulex are maintained in 100 ml plastic beakers Twenty-four (24) beakers with one organism each are kept at all times to ensure continuous availability of neonates for testing Cultures of individual Ceriodaphnia dubia are maintained in 30 ml sterile plastic medicine cups One to two cultures of approximately 100 organisms each are kept at all times

Document Control Number 7006 Page 2 of 3______________________________________________

32 Cultures are renewed three times per week Organisms are fed daily

40 Obtaining Neonates for Testing

41 Cultures of Ceriodaphnia are started by placing one neonate into a 30 ml disposable plastic cup containing approximately 20 ml of Moderately Hard Synthetic Water New Ceriodaphnia cultures are started every ten to fourteen days D magna and D putex are replaced whenever mortality occurs

42 The individual cultures are transferred to fresh media three times per week Synthetic water algae and YCT are mixed prior to pouring into culture vessel to ensure uniformity of media The old media and neonates are kept for stock cultures for several weeks and then discarded

43 To assure neonates for chronic tests are of a very similar age transfer of individual brood stock to fresh media should be made the morning of the test The cultures are then checked approximately every two hours to find an adequate number of neonates all released with an 8 hour period For acute tests individuals are either transferred less than 24 hours before a test or the young are separated from adults less than 24 hours before a test

44 Young used in chronic testing are obtained from adults who have produced at least three broods with no less than 8 neonates in their third or subsequent brood Neonates are then distributed in a blocking procedure ie neonates from the same organism are placed in one replication of each concentration

50 DAPHNIA Food

51 Digested Flake Food

511 Add 5g flake food to 1 L deionized water Mix well in a blender and place in a 2 L separatory funnel To digest aerate this mixture at room temperature for one week
