1 PROJECT SUMMARY

11 INTRODUCTION

This Completion of Removal Action Report summarizes the construction quality assurance (CQA) activities performed for the Non-Time Critical Removal Action (NTCRA) design and construction of the Landfill Closure Project at the Saco Municipal Landfill Saco Maine It is provided to fulfill the requirements of the US Environmental Protection Agency (EPA) Statement of Work (SOW) for the NTCRA and also Maine Department of Environmental Protection (MEDEP) Maine Solid Waste Management Regulations

12 PROJECT HISTORY

The Saco Municipal Landfill Saco Maine served as a disposal site for municipal commercial and industrial wastes from approximately 1963 to 1988 The 90plusmn acre site owned by the City of Saco contained four separate landfill areas (Areas 1 2 3 and 4)

In 1990 the EPA placed the site on the National Priorities List and by November 1995 the City of Saco entered into an Administrative Order by Consent (USEPA CERCLA Docket No I-CERCLA-95-1069) to conduct a Remedial Investigation a Feasibility Study and an Engineering Evaluation Cost Analysis (EECA)

Based on the preliminary results of Phase 1A Remedial Investigation the EPA identified conditions at the site that indicated it was appropriate to conduct a NTCRA at Landfill Areas 3 and 4 Landfill Areas 3 and 4 can generally be described as the two disposal areas on the site located southwesterly of Sandy Brook Landfill Areas 3 and 4 are contiguous to each other but with a different history of use Landfill Area 4 was operated from about 1974 to 1989 and accepted primarily municipal solid waste The waste was covered with soil but the area had not received a final cover system prior to the NTCRA Landfill Area 3 was developed around 1985 to serve as an industrial waste storage area A considerable amount of the stored industrial waste material in Area 3 was removed in 1992 with the approval of the MEDEP however some wastes remained

In July 1996 the City of Saco submitted an EECA describing site conditions and proposed remedial alternatives for Landfill Areas 3 and 4 An Action Memorandum documenting the selection of a multi-barrier cover system waste consolidation and focused sediment removal as the preferred remedial activity for these areas was prepared and signed by the EPA in September 1996 The Action Memorandum required

1 Excavation of all sediments in the ground water seep adjacent to Sandy Brook having an arsenic concentration above 19 mgkg

2 The design and construction of a multi-layer low hydraulic conductivity cap over the landfill 3 Long Term Monitoring of ground water surface water and sediments 4 Post-Removal Site Control and 5 Institutional Controls

9606401 1 051299 SacoF-CERT02-99IIdoc

In May 1997 an Administrative Order By Consent for Removal Action (US EPA Region 1 CERCLA Docket No CERCLA-I-97-1009) the Order was signed to allow implementation of the removal action at the Saco Municipal Landfill site

The performance standards for the NTCRA are specified in the Action Memorandum and Statement of Work The performance standards include Sediment Excavation and Consolidation Consolidation of Solid Waste Landfill Cap Surface Waters Air Long Term Monitoring Post Removal Site Control and Institutional Controls

The design for the NTCRA was concurrent with the Order approval process A draft Order was available and on this basis a Design Report Specifications Drawings and Construction Quality Assurance Plan were developed to assure achievement of the anticipated NTCRA Performance Standards The Design Work Plan for Sediment Removal Action dated December 1996 and Design Report (Amended) dated May 29 1997 may be referenced for detailed information of the design

Prior to the Order approval the City of Saco commenced activities to remove ground water seep sediments in December 1996 and to allow work for the landfill cap to start in May 1997 Although these activities were in advance of approval of the Order the City of Saco elected to accept the risk and obtain an early start on NTCRA activities which via understandings from discussions with the EPA and MEDEP would presumably be approved with few if any changes The advanced start by the City was beneficial It shortened the time to project completion by taking advantage of the 1997 construction season thus promptly addressing environmental issues at the site

On July 10 1997 the EPA approved with conditions the Final Design for the NTCRA Efforts to complete the performance standards have ensued The performance standards of the Order have been completed with the exception of Long Term Monitoring and Post Removal Site Control which continue into the future Institutional Controls have been developed and are currently being finalized by the EPA MEDEP and the City of Saco

14 CONSTRUCTION PROJECT DESCRIPTION

Construction for the NTCRA involved removal of sediments from a seep adjacent to Sandy Brook locating the waste boundary of Landfills 3 and 4 consolidation and grading of waste installation of gas vents construction of the composite cap surface drainage controls and permanent stabilization of the disturbed area for erosion prevention

Woodard amp Curran provided resident engineering services and construction administration support to the projects owner City of Saco Maine Woodard amp Curran utilized the services of four firms to support the effort SW Cole Engineering Inc Bangor Maine provided soils testing inspection and consultation services JampL Engineering Inc of Canonsburg Pennsylvania provided geosynthetics inspection consultation and certification services GeoSyntec Consultants Inc of Atlanta Georgia furnished independent review of the JampL Engineering services TRI Environmental Austin Texas provided laboratory testing of geosynthetic materials GeoTesting Express Boxborough Massachusetts provided interface shear testing

The general contractor for the landfill cap construction project was HE Sargent Inc Stillwater Maine As subcontractor RTD Enterprises of Madison Maine provided geomembrane liner installation The approximate cost of the landfill cap construction work was 23 million dollars

141 Waste Limit Determination

Waste boundary determination was an initial task accomplished This work involved excavating test pits along the perimeter of the apparent waste deposit A marker was set at the point where the test pit no

9606401 051299 Saco F-CERT 02-99 Hdoc

longer evidenced waste deposition These markers established the waste limit The markers were surveyed and reset as work proceeded All waste relocation and grading of wastes were performed with the intent of consolidating all wastes within these established bounds

142 Waste Relocation Grading

Waste relocation was the consolidation of wastes from other areas of the site into the Landfills 3 and 4 prior to installation of the cap system The waste relocation was from four waste removal areas and also from a seep adjacent to Sandy Brook

Grading of the landfills waste mass was necessary to obtain suitable surface grades for slope stability and drainage This work was performed by either pushing the wastes or by excavation and hauling with the end result being the prepared grades necessary for installation of the composite cap

143 Cap Construction

Cap construction consisted of the installation of soils and geosynthetic components in layered fashion to produce the completed cap Vent pipes to permit the controlled release of gases through the cap were included in this process Work to construct the cap was staged such that various layers of the cap were being installed at any particular stage of the cap construction

For identification purposes the construction Contractor divided the cap construction into five Work Areas which roughly represented the planned sequence of the cap construction ie Work Area 1 was the first to start and Work Area 5 the last to be completed These work areas were not bound by surveyed divisions of the cap but were only divided by imaginary lines with the intent of providing general nomenclature for discussions and documentation The approximate divisions of the Work Areas may be seen on Plan Sheet 5A Appendix B5 - Record Drawings During execution of the cap construction the work activities were not constrained by nor perfectly sequential with the Work Area numbering As an example geomcmbrane was installed in Work Area 4 before being installed in Work Area 3

144 Surface Drainage

Stormwater drainage from the surface of the landfill cap and immediate surroundings is conveyed by a designed system of slope benches channels and culvert pipes

To control the discharge of sediments from the site a sediment retention basin was constructed downhill of the cap construction area and stormwater flow directed to the basin by channels and culvert pipes During construction activity the basin accumulated but did not discharge sediment laden stormwater Upon stabilization of the majority of the surfaces within the basins drainage the sediments were removed from the basin and an outlet structure installed to control the release rate of future storm flows

145 Surface Stabilization

The surfaces of the landfill cap drainage conveyances and surrounding disturbed soil areas were permanently stabilized against erosion with vegetation use of riprap stone or gabion baskets The specific locations of each type of installation were governed by the design

3 WASTE REMOVAL AND RELOCATION

One aspect of the NTCRA was to excavate the wastes from outside of the landfill limits and move the waste to locations in Landfill 3 and 4 for eventual coverage by the landfill cap Four waste disposal locations outside of the Landfill 3 and 4 boundary were identified during the NTCRA design stages of the project For purposes of identification these locations are called Waste Removal Areas (WRA) and have been assigned letters A B C and D In addition removal of arsenic contaminated sediments from a seep area adjacent to Sandy Brook occurred in December 1996 These seep sediments were excavated and relocated to Landfill 3 at a disposal location depicted on the Plan sheets Additional non-hazardous seep sediments were excavated in November 1998 and disposed of off-site at a licensed disposal facility in Nomdgewock Maine

Locations of each WRA and the seep area can be referenced on Plan Sheet 2 - Area Site Plan

In each WRA vastes and soil were excavated to what appeared to be native soils Upon completion of the excavation removal the excavations were made available to the EPA for observation and for concurrence that waste materials had been removed to native soils

The NTCRA design did not require identification of the waste materials hich were relocated No information regarding the relocated astes or their composition is provided

31 WRA A

Excavation of WRA A began June 30 1997 and was completed July 7 1997 During this activity monitoring ell 95-3S as removed because this shallov well vas set into the soil and aste which vere excavated

Upon completion of the removal the excavation was refilled with borrow soil and final grades established One large concrete mass in excess of one cubic gtard m size was allowed to remain within the excavation The block was moved to ensure no waste was present below the block Afterwards this block was buned within the refill soil approximate) 15 feet northeast of monitoring well 95-3R

32 WRA B

WRA B is adjacent to Landfill 3 on the northwestern comer of the landfill

Excavation of WRA B began June 24 1997 and was completed shortly thereafter Borrow soil was placed in the lowest area of the excavation to restore surface drainage The surface was seeded and mulched to establish vegetation

33 WRA C

WRA C was an extension of Landfill 3 in a southerly direction

Waste removal in WRA C began June 20 1997 and was completed June 24 1997 In portions of WRA C it was necessary to remove material to the underlying bedrock Upon completion of the removal

9606401 10 051299 Saco F-CERT 02-99 II doc

excavation the excavation was refilled with borrow soil to grades necessary for surface water drainage Soil surfaces were covered with topsoil and seeded The bedrock was left exposed

34 WRA D

WRA D is located separately from Landfills 3 and 4 along the easterly side of the entrance road to the site

In preparation for excavation trees and brush were cut however stumps were left in-place to be removed with the wastes Waste removal excavation began June 26 1997 and was completed July 2 1997 The final surface was graded to promote water drainage and seeded to establish vegetation

35 WASTE REGRADING

The landfill waste mass required reshaping to create the initial base which later provided suitable slopes for stability and drainage This work was accomplished by pushing of wastes or by excavating and hauling these wastes to other locations within the landfill Wastes transferred within the landfill during the regrading were compacted upon placement

36 SEEP SEDIMENT REMOVAL

In December 1996 arsenic contaminated sediments from a seep area adjacent to Sandy Brook were mitigated by excavation and consolidation within the Landfill Area 3 This sediment removal action was a first step of the NTCRA to limit exposure to site related contaminates

Removal of the contaminated sediments was accomplished by procedures presented within the Design Work Plan for Sediment Removal Action Saco Municipal Landfill December 12 1997 appearing in Appendix El The overall approach was to implement erosion and sediment control create access to the area stage the construction then systematically excavate the sediments and haul them to a disposal location on Landfill Area 3 Clean refill soils were placed within the excavated area graded and the surface stabilized

The work activity of sediment removal occurred from December 12 1996 through January 9 1997 Information documenting the sediment removal activity memos wetland report and analytical test data are presented in Appendix E2 - Sediment Removal Action Supporting Documents

In November 1998 a second sediment removal action was conducted Arsenic contaminated sediments from a seep area adjacent to Sandy Brook were mitigated by excavation and off site disposal Removal of the sediments was accomplished by procedures presented in the Design Work Plan for the Sediment Removal Action Saco Municipal Landfill October 1998 and included in appendix El Similar to the December 1996 sediment removal action the overall approach was to implement erosion and sediment control and systematically excavate the contaminated sediments and dispose off-site at an appropriate landfill Sediments were tested for hazardous waste characteristics and found to be non-hazardous material Clean refill soil were placed within the excavated area and mulch applied to the surface

The work activity for this sediment removal occurred on November 3 1998 Excavated sediments were stored on-site in roll-off containers until January 7 1999 Analytical results indicated the sediments to be

9606401 11 051299 Saco F-CERT 02-99 Ildoc

non-hazardous and on January 4 1999 a Solid Waste License was approved allowing the off-site disposal of these sediments at a solid waste landfill disposal facility in Norridgewock Maine Information documenting the sediment removal activity are presented in Appendix E2

9606401 12 051299 Saco F-CERT 02-99 Hdoc

4 LANDFILL CAP

Cap design and construction provides for gas release from the wastes subsurface drainage of water above the barrier layer surface drainage of precipitation and a stabilized final surface to protect against erosion

41 PASSIVE GAS VENTING

The landfill cap design incorporated venting structures to collect gas generated from the decomposition of wastes and allow the gas to exit through the cap while preventing a reverse flow of water into the landfill

411 Vents

A total of 20 gas vent structures were installed in the landfill prior to the placement of the barrier layer The gas vents consist of two components a passive collection section buried within the wastes and the vent piping to the atmosphere Perforated piping nine feet below the surface of the landfill is surrounded by a crushed stone and geotextile fabric envelope which passively collect the gases These gases are then vented up through a solid wall pipe which extends six to ten feet above the surface of the landfill

CWDs 25A and 25B allowed dimensional changes to the gas vent riser pipe the soil mound at its base its geomembrane boot and the alignment relative to the vertical position

412 Ambient Air Monitoring

The Air Monitoring Program for Landfill 3 and 4 vas performed on July 2 1998 The results of the monitoring are presented in Appendix H - the Landfill 3 amp 4 Air Sampling Report The testing detected acetone and ethanol at levels well below the most stringent 8-hour exposure standards No other compounds tested were detected

42 SUBSURFACE DRAINAGE

The cap drainage layer consists of sand and perforated pipes placed above the barrier layer Water within the drainage layer is discharged from pipe outlets and a riprap drainage zone located around the perimeter of the cap

421 Drainage Layer

The drainage layer consists of a sand drainage layer and perforated piping installed on top of the geomembrane The pipes discharge to surface locations around the perimeter of the landfill Plan Sheet 5A of Appendix B5 - Record Drawings shows the locations of the underdrain pipes installed within the drainage sand layer of the cap

Per design requirements the drainage pipes located at the bottom of each slope bench are placed within an envelope of geotextile fabric and crushed stone The drainage pipes located at intervals between slope benches consists of perforated pipe which is wrapped in a geotextile fabric No crushed stone surrounds these pipes

9606401 13 051299 Saco F-CERT 02-99 Ildoc

422 Cover Termination

The cover termination design provides for the release of water from the cap drainage layer The majority of the termination construction detail has a riprap stone layer in hydraulic contact with the drainage layer Water from the drainage sand passes into the riprap stone exits the stone and subsequently becomes surface water One segment of cover termination between perimeter stations 19+75 to 25+50 does not have the riprap layer In this section of cover termination perforated piping within the drainage layer is primary point of release for the drainage layer water Refer to CWD 13 for detailing of this particular termination and sheet 5A - Record Drawings Appendix B5 for station locations

Perforated piping within the drainage layer provides another means of releasing water from the drainage layer These pipes day light to the surface at intervals around the perimeter of the landfill From observation of the pipe outlets following an extended period of rainfall during June 1998 water was flowing from the pipes which connect to slope bench piping at stations 0+00 16+70 and 28+00 Very low flows were observed from pipes at 9+83 12+37 and 19+50 Other pipe outlets were dry This observation indicates the primary release of drainage layer water at the cap termination is through the riprap drainage zone and the drainage pipe outlets are a secondary release point

The cover termination received major design changes during the course of construction CWDs 13 14 and 23 revised the riprap and drainage piping in termination Refer to these CWDs in Appendix B2 - Change in Work Directives for additional information

43 SURFACE DRAINAGE

Specific construction issues were identified for the slope benches downdrain channels perimeter channels and culverts which provide surface drainage These are described below

431 Slope Benches

Slope bench channels convey the flow in controlled manner to the dovndrain channels or to surface drainage channels along the perimeter of the cap

Construction of barrier soil to obtain the slope bench V geometry proved to be difficult Significant efforts by the contractor were applied in Test Pads 2 and 3 to be able to demonstrate successful construction A design change with smoother angular transitions was issued as CWD 9 to improve the slope bench construction

The construction of the slope bench channels resulted in variation of the side slopes CWD 24 provided allowable tolerances for channel width depth and side slopes which fulfill the design requirements for capacity

At the time of Substantial Completion inspections portions of the slope bench channels contained sediment deposition within the riprap stone CWD 43 was produced to establish an acceptable depth of these sediments deposits The sediment deposits were removed to the acceptable level before final completion by flushing with water from a hose and using hand tools

432 Downdrain Channels

Downdrains are the gabion mat lined channels which convey stormwater down the steepest slope gradients of the cap

A design issue existed relative to the construction at the confluence of the slope bench channel with the downdrain Here a riprap stone channel blends into the gabion mat channel Concern had been raised by the MEDEP as to whether the riprap stones at the confluence would move with the water flow Observation of the location upon spring thaw and during two heavy precipitation events has not found movement of the riprap stones As such it is proposed to leave the channel intersection as constructed

Inspections also found subtle variations in the width and depth of the downdrains CWD 31 provides the acceptance of the observed channel dimensions Reference Appendix B2 - Change in Work Directives for more information

The Contract Drawings required a gabion wall at the toe of the slope of the downdrain channel on the east side of the landfill After the gabion wall was installed by the Contractor a non-conformance was observed in that the required amount of fasteners were not installed in the gabion baskets The Contractors proposed solution to this problem was to install an additional gabion wall in front of the non-conforming wall rather than dismantle and re-do the existing work This proposal was submitted as CWD 29B was accepted and the additional work was performed to rectify the non-conformance

433 Perimeter channels

Perimeter drainage channels are the water conveyances which exist around a majority of the cap termination Details of cap termination construction provide information regarding construction of the channels

Two CWDs were issued for the perimeter drainage channels CWD 32 was issued to address and accept drainage channel side slopes that were different than original design CWD 49 was issued to address stabilization of channel segments where establishing vegetation was difficult due to the frequent presence of water Stone lining was provided in the bottom portions of the perimeter channels experiencing the problem

434 Culvert Pipes

The culvert pipes installations and associated riprap aprons plunge pools and manholes were observed to have disparities from the design plans CWDs 35 36 37 38 and 39 appearing in Appendix B2 - Change in Work Directives address this issue with changes and acceptance criteria for the culvert pipe systems and their inlet-outlet stabilization The Record Drawings Appendix B5 contain the as-built elevations of the culvert pipe inverts

44 SURFACE STABILIZATION

The surface of the landfill was permanently stabilized by the growth of vegetation and the use of riprap stone and gabion baskets in drainage conveyances Prior to the growth of vegetation on the cover erosion was prevented by the placement of erosion control blanket placed over the topsoil and seed layer on the entire landfill cap With the growth of the vegetative root mat the slopes were stabilized Drainage conveyances were lined with riprap stone and at the main downdrains gabion baskets were installed to provide long term protection against erosion

45 LANDFILL CAP SOILS

Soils comprised a significant component of the landfill cap design A brief description of the soil source for each cap layer and the tests performed to qualify the soil material are described in the following sections

451 Base Cover Soil

The base cover soil was used to cover wastes and to fill irregularities providing a smooth surface for the subsequent gas transmission layer Base cover soil was applied in sufficient thickness to cover the underlying wastes

The base cover soil was obtained from the City Borrow Pit located on the landfill site property Seven samples were collected from the delivered soils and tested for gradation The base cover soil generally consisted of a fine silty sand and is similar in gradation to select borrow which was obtained from the same pit

452 Gas Transmission Sand

The gas transmission sand was obtained by the Contractor from the Fenderson Pit on State Route 5 Saco Maine

Seven samples were collected from test pit excavations at the source pit on July 8 1997 and another 13 samples were collected from the delivered and placed material All soil samples exhibited very similar gradation hydraulic conductivity and physical properties One source sample 127 exhibited marginal hydraulic conductivity of 000098 cmsec nearly equal to the specified 00010 cmsec requirement The marginal hydraulic conductivity of source sample 127 is described in Section 723

Copies of a summary of the test data and met the laboratory reports for the gas transmission sand appear in Appendix C2 - Gas Transmission Sand The results of the in place density and moisture content with their locations appears in Appendix C8 - In-Place Tests of Soil Moisture amp Density

453 Barrier Soil

Barrier soil provided for the project consisted of a silty clay soil obtained from a geologic soil deposit locally known as the Presumpscot Formation

Two soil source locations were required to complete the project These are identified as the Watson Pit and the Cole Dairy Pit

9606401 16^ ~ OJ1299 Sraquoco F-CERT 02-99 Ildoc

4531 Watson Pit

The Watson Pit was located on the westerly side of Louden Road in Saco Maine This pit provided barrier soil used for the project during the period of July 28 to September 17 1997

Appendix Dl - Barrier Soil and Test Pad Construction Report provides details of the soil source exploration and testing program Zone of Acceptance (ZOA) development and construction procedures used for the Watson Pit barrier soil As described in the report a ZOA for the Watson Pit barrier soil was established using compaction hydraulic conductivity and shear strength data as specified

Project design anticipated that measurement of in place soil moisture content using a nuclear device could produce erroneous results due to properties of the soils machine calibration and other factors Accurate moisture content measurements were imperative because testing and acceptance of soil moisture relied heavily upon the nuclear device From testing activity performed on Test Pad 1 in place measurement of the barrier soil moisture content by nuclear method produced results which were generally lower than the laboratory test method ASTM D-2216 A means to correct for the difference in test methods was implemented CWDs 6A and 6B provide discussion of the procedures used to provide quality assurance of the barrier soil moisture content by confirming the validity of the nuclear test device results Refer to these CWDs in Appendix B2 - Change in Work Directives for more information

During placement of the Watson soil it became evident that the Watson Pit had variations in material properties which influenced the compaction of the soil As additional soils data became available it was determined there was greater variability of the soil source than had been identified by the source testing program Section 719 of this report provides further information about the variation Modification of the ZOA was necessary to provide acceptance criteria for barrier soil not qualified in the original source testing program Change in Work Directive 21 was issued to expand the Watson soil ZOA Figure 1 shows the original and expanded ZOA for the Watson Pit soil

4532 Cole Dairy Pit

The first barrier soil source known as the Watson Pit contained insufficient soil material to complete the compacted soil barrier layer The contractor HE Sargent promptly located another soil source known as the Cole Dairy Pit in Dayton Maine and performed preliminary sampling Observed properties and laboratory testing of the preliminary sample indicated a clay material having suitable gradation and hydraulic conductivity for use as a barrier soil Subsequently a source exploration program was done on September 6 1997 Laboratory testing was performed following the requirements of specification Section 02200 306B All tests results from the soil source samples indicated the soils met specified requirements and were favorable for use as the compacted barrier layer A ZOA for the specific soil source was developed from the test program Figure 2 shows the ZOA for the barrier soil obtained at the Cole Dairy Pit

The Cole Dairy Pit provided the barrier soil from September 20 1997 to the completion of the project Approximately 15000 cubic yards of this soil as installed

4533 Test Pad Reports

Test Pads were constructed to verify that the materials and construction procedures used were capable of producing a soil barrier that achieved the desired low hydraulic conductivity Hydraulic conductivity testing was performed on the Test Pads 1 and 4 to verify the relationship between the moisture content density and the hydraulic conductivity of the installed soil Test Pads 2 and 3 were primarily used to evaluate construction methods and did not include hydraulic conductivity tests Refer to Appendix C3 shyBarrier Soil Test Pad Hydraulic Conductivity

45331 Test Pads 1 amp2

Documentation for the Test Pads 1 and 2 appear in Appendix Dl - Barrier Soil and Test Pad Construction Report (Amended) The report is amended in that it contains text and data provided as response to comments from EPA via TRC Environmental dated July 16 1997

9606401 19 051299 Saco F-CERT 02-99 lldoc

The first two test pads revealed potential difficulties with construction and in the testing methods Equipment used to construct the barrier layer affected the barrier soil Placed lift thickness variation occurred at both the top surface and at the gas sand interface below Construction of slope bench geometry was also affected by the type and size of equipment used Heavy rolling equipment tended to move the soil and change its geometry

Testing of density and moisture content of the barrier soil Shelby tube sampling of soil distorted the specimens during the sampling and testing procedure thus affecting the sample volume Whereas measurement of soil density was not the intent of the shelby tube samples this was not a critical measurement and density measurements of soil samples obtained from shelby tubes were not used for comparison with nuclear density measurements made in the field A similar condition was found with using the sand cone test method to determine in place soil density The soil distorted into the test hole dug during the test affecting the sample volume measurement Changes to testing procedures contained within CWD 6 eliminated use of the sand cone test method

45332 Test Pad 3

Test Pad 3 was constructed within the production placement of the first barrier soil on the landfill Its pnmarv purpose was to demonstrate the construction of a slope bench with the bamer soil layer the process used to protect installed bamer soil and verification of soil moisture content measured by nuclear method The approach to performing Test Pad 3 appears in Appendix D2 - Test Pad 3 Activities and Work Plan

A construction difficulty encountered by the Contractor was the ability to construct the slope bench in accordance ith the plans and specifications A high level of effort was necessary The use of an excavator with a flexible wnst grading bucket did allow the required V geometry to be formed in the bamer soil lagtcr However the surface of the clav would have required additional work to prepare it to a geomembrane ready surface Additional) placement of the geomembrane in the V ditch would have consistent) resulted in bridging of the geomembrane which would have resulted in a non-conformance Eentuall) CWD 9 was issued changing the geometn of the slope bench to a shape more easil) constructed

An EPA correspondence of August 1 1997 provides concurrence that Test Pad 3 was constructed in accordance with the Work Plan and demonstrated slope bench configuration could be achieved Refer to CWDs 5 6 and 6A contained in Appendix B2 - Change in Work Directives for the changes resulting from Test Pad 3 execution

45333 Test Pad 4

Test Pad 4 was constructed on September 18 and 19 1997 to test and demonstrate installation of the Cole Dairy- Pit barrier soil source described in Section 4 53 2 of this report would achieve requirements specified for the project Test Pad 4 was constructed per specifications and CQA Plan No separate work plan or report for Test Pad 4 was prepared

Test Pad 4 pass-fail acceptance was based on a proposed ZOA for the Cole Dairy Pit soil which was later modified following the outcome of the test pad work During execution of Test Pad 4 on the first lift of bamer soil Field MoistureDensity Test 498 was taken and was initially determined to be a failing

9606401 20 051299 Saco F-CERT 02-99 II doc

test because the measured density of 982 pcf was below the allowable minimum of the then proposed ZOA for this soil source The Contractor performed additional compactive effort on the area and Test 500 was performed as a retest of Test 498 The density went up slightly to 989 pcf but the moisture content went down to 203 Moisture content was below the minimum 21 allowable for the proposed ZOA Upon completing Test Pad 4 the proposed ZOA was modified to accept lower soil densities and Test 498 then became a passing test in this modified final ZOA The lower than specified moisture content of test 500 was accepted in light of the previous passing test because this particular test was used in a Test Pad circumstance to determine if additional compactor passes increased soil density Although test 500 is formally a non-conformance it does not indicate a lack of quality in the installed barrier material layer

Refer to Change in Work Directive 22 contained in Appendix B2 for the discussion and results of Test Pad 4

4534 Barrier Soil Variants

An empirical evaluation of the barrier soil source in place data and ZOA suggests the soil sources contained variations of the Presumpscot Soil Formation which include both silts and clays

The Watson Pit appears to have contained silt and clay variations both being able to yield a low hydraulic conductivity when compacted The variation identified as silt had higher maximum dry densities (circa 110 lbft3) and lower optimum moisture contents (circa 18) as well as lower plastic indexes (circa 12) and lower percentages of the 0002 mm particle size (circa 35) The variation with a higher clay fraction had lower maximum dry densities (circa 100 lbft3) and higher optimum moisture contents (circa 21) as well as higher plastic indexes (circa 16 to 20) and higher percentages of the 0002 mm particle size (circa 50)

The variation of the Watson Pit source was most apparent on material installed within Work Areas 2 and 5 in the general southeast quadrant of the Landfill 4 Here the Watson soil appeared to have compacted thoroughly provided a firm surface yet remained outside the ZOA Collection of additional soils samples found further evidence of variation in the soil properties Change in Work Directive 21 presents a discussion of the Watson Soil variation and an expansion of the Watson Pit ZOA to address the variation

Per the criteria above soils from the Cole Dairy Pit would qualify as a clay variation The Cole Dairy-soils did not exhibit the silt variations observed with the Watson Pit soil

454 Drainage Sand

Drainage sand provided for the project by the Contractor was obtained from Dayton Sand and Gravel Dayton Maine The drainage sand is a manufactured soil material typically used for concrete

Nine samples of the sand were obtained from the source pile on July 11 1997 and another 22 samples were collected from the delivered and placed material The soil samples exhibited very similar gradation hydraulic conductivity and properties Gradation testing indicated all particles to be less than 38-inch size All samples conformed to specified requirements

Copies of a summary of the test data for the drainage sand with the supporting laboratory reports appear in Appendix C4 - Drainage Sand The results of the in place density and moisture content with their locations appears in Appendix C8 - In-Place Tests of Soil Moisture amp Density

9606401 21 051299 Saco F-CERT 02-99 Hdoc

455 Select Borrow

Select borrow soil was obtained from two sources One source was the City Borrow Pit located on the landfill site property The other source was an extension of an existing soils pit on the abutting Patterson property to the southwest of the landfill Although the soil was obtained from two locations that are approximately 1500 feet distant from each other the soil was of similar geologic origin and exhibited similar gradations and proctor test results Overall the soil would classify as a fine silty sand

Eleven samples were collected from the soil delivered to the landfill and tested for gradation Eight of the samples also had proctor tests performed

Copies of a summary of the test data and the laboratory reports for the select borrow appear in Appendix C5 - Select Borrow The results of the in-place density and moisture content tests with their locations appears in Appendix C8 - In-Place Tests of Soil Moisture amp Density

456 Topsoil

Topsoil used for the landfill cap was a blended mixture of municipal wastewater compost and borrow soil Data regarding the composition of the compost and the nutrient content of the mixed topsoil (before fertilizer amendment) appears in Appendix C7 - Compost amp Topsoil

5 GEOSYNTHETICS DOCUMENTATION

Construction quality assurance testing and inspection of the geotextile fabrics and geomembrane liner components were performed on the project in general conformance with the requirements of the Construction Quality Assurance (CQA) Plan incorporated into the technical specifications of the project The CQA Plan required that the geomembrane and geotextile material and installation quality assurance be provided by a qualified independent Geosynthetics Construction Quality Assurance Representative The Geosynthetics CQA Representative for this project was JampL Engineering Inc of Canonsburg Pennsylvania

A general description of the geosynthetic materials used on this project is the following

All geomembrane products utilized for this project were manufactured by Columbia Geosystems Ltd a wholly owned subsidiary of National Seal Company The geomembrane product installed as the barrier material was Geodex Friction Seal a textured surface LLDPE geomembrane of nominal 60 mil thickness Geodex Friction Seal LLDPE geomembrane of nominal 40 mil thickness was used in slope bench and downdrain channel construction as indicated on the plan drawings

The woven type geotextile fabric utilized for the project was model 700X manufactured by Mirafi The 700X geotextile fabric was generally installed in areas off of the landfill cap beneath riprap stone protection used for drainage channels and culvert outlet protection areas

Non-woven type geotextile fabrics installed were models 180N and the 1160N manufactured by Mirafi The primary use of these fabrics was the separation of soils in drainage layer applications

51 JampL ENGINEERING INC CERTIFICATION REPORT

Material acceptance and installation certification of the geosynthetic components are provided in a separate document Geosynthetics Construction Documentation and Certification Saco Municipal Landfill Closure prepared by JampL Engineering Inc which is presented as Volumes 3 and 4 of this report The roles and responsibilities of the Geosynthetics Construction Quality Assurance Representative for this project are described in the CQA Plan incorporated into the technical specifications of the project and they are outlined in the Certification Report by JampL Engineering Inc JampL Engineering provided a full-time resident project representative during the placement of geosynthetic materials documented the testing of geomembrane materials and installation reviewed the Contractors geosynthetic submittals recommended solutions to geosynthetic construction issues and provided the certification of the geosynthetic installation

After the preliminary Certification report from JampL Engineering was reviewed it was determined that portions of the required documentation of the geomembrane installation was not recorded and that decisions were made by JampL Engineering which did not fully conform with the requirements of the CQA Plan Although JampL Engineering and the Contractors geomembrane installer were positive that all the required testing was performed and that the geomembrane installation was of very high quality the missing documentation and other non-conformance issues resulted in significant questions about the quality of the geomembrane installation Further information about the geomembrane installation non-conformance appears within Section 722

9606401 23 031299 Saco F-CERT 02-99 Ildoc

6 INTERFACE SHEAR TEST

Project specifications required interface direct shear testing for interfaces within the cover system using the materials incorporated into the landfill cap

Testing of the sand - geomembrane interface and the Watson Pit barrier soil - geomembrane interface were performed by GeoTesting Express Boxborough Massachusetts Testing of the Cole Dairy Pit barrier soil - geomembrane interface were performed by TRI Environmental Inc Austin Texas Both laboratories are Geosynthetic Accreditation Institute (GAI) certified for the ASTM D5321 test procedure use

The results of the laboratory testing for the interfaces are presented in Appendix C9 - Interface Shear Test Reports

61 SAND - GEOMEMBRANE

7 SPECIAL ISSUES amp NON-CONFORMANCE

The special issues in Section 71 presents particular events or changes that had occurred during the execution of the work Section 72 non-conformance includes presentation and resolution of nonshyconforming items which were not addressed by rework or replacement and correction

71 SPECIAL ISSUES

This Special Issues section refers to topics that were identified during the execution of the NTCRA design and construction that required supplementary attention The Special Issues result from design approval conditions by EPA observation of the work unanticipated circumstances accidents or other causes

711 Landfill 2

Landfill 2 is a previously closed Municipal Solid Waste located on the same City of Saco land parcel as Landfills 3 and 4 Repairs and improvements to Landfill 2 cap were included in the construction contract for the cap of Landfills 3 and 4 Although part of the construction contract the Landfill 2 work is independent of the NTCRA design and is not elaborated on further in this document

712 Waste Stumps

On July 10 1997 it as observed that site clearing activities were producing a large quantity of tree stumps Some stumps were also being uncovered during waste relocation activities Concern was raised that the placement of whole tree stumps into the landfill would cause voids upon decomposition and this would have potential to introduce settlement and stress on the cover system

To address the concern all stumps exposed by waste grading or clearing activity were temporarily stockpiled together On September 10 1997 a tub grinder machine was used to shred the collected tree stumps The ood shreds were then dispersed into the waste mass primarily within Work Area 5 before placement of base cover soil

713 Frost Protection

Condition 2 of EPA approval of the NTCRA design as issued July 10 1997 required the thickness of the cap above the geomembrane shall be at least 36 inches on all north facing slopes and at least 30 inches on all other areas This condition was included in the approval of the design to ensure adequate frost protection was provided

For purposes of implementing the approval condition a north south dividing line also called the Mason-Dixon line was produced to distinguish the division of the two cap thickness This line appears on Record Drawings Plan Sheet 5A Appendix B6 - Record Drawings The thickness of the select borrow layer of the cap design was increased on the north side of the line to implement the requirement stated above

9606401 30 Oi1299 Saco F-CERT 02-99 II doc

714 In-PIace Measurements of Barrier Soil Moisture

Moisture content of the in-place barrier soil was determined by two methods nuclear device method [ASTM D3017] and laboratory determination by drying [ASTM D2216] The purpose of the two methods was to provide quality assurance by a comparative means of identifying erroneous readings from the nuclear device as well as providing a means to calibrate the nuclear device

Efforts to compare barrier soil moisture commenced during the implementation of Test Pad 1 and continued throughout the installation of barrier soil CWDs 6 6A and 6B presented in Appendix B2 - Change in Work Directives discuss the comparative method the data the results and provide revision of the specifications to accomplish the quality assurance of barrier soil moisture content measurement

Appendix C3 - Barrier Soil Moisture Content Comparisons provides a summary of all paired moisture content measurements statistics of the collected data and graphic plots of the paired data

715 Geotextile Fabric

Non-conforming geotextile fabrics were identified through conformance testing of the delivered materials The non-conformance was specific to identifiable material production lots

Conformance testing of Mirafi geotextile model 180N lot 646 determined non-conformance with AOS grab elongation and trapezoidal tear properties The AOS non-conformance was resolved by retesting where 15 of 15 samples retested positive and thus were accepted Change in Work Directives 16 17 19 and 20 were issued to clarify the design intent and permit acceptance of the material relative to the other non-conforming properties

Conformance testing of Mirafi geotextile model 1160N lot 613 determined non-conformance with permitivitty specifications As a result this lot of material was rejected and not used in the construction nor incorporated into the work

716 Geomembrane Bridging

Geomembrane bridging is tensioning of the sheet resulting from temperature changes and contraction of the material Geomembrane installed at a warm temperature shrinks when cooled

Bridging of the geomembrane was primarily observed in the slope benches following the first two geomembrane installation events At the time the bridging was observed the geomembrane had not been covered with soil The geomembrane installer adjusted sand bag ballast weighting tensioned sections and unweighting loose ends permitting the free ends to move slightly and relieve tension areas Tension was also released as the geomembrane expanded as it warmed during the day The drainage sand layer was not installed over the geomembrane until the bridging was removed

717 Fuel Spill

A vehicle accident on September 22 1997 involving a road sweeper and the water truck resulted in a fuel being spilled from the water truck fuel tank The accident and spill occurred on the southerly access road downhill of MW-95-8R

9606401 31 051299 Saco F-CERT 02-99 Ildoc

Authorities were notified of the spill and cleanup activity of the spilled fuel immediately followed the accident

718 Leachate Breakouts

Following completion of waste grading and base cover soil placement but prior to barrier soil installation breakouts of leachate were observed in the general area of the slope bench down hill of gas vent 12 This location is shown on the Appendix B5 - Record Drawings sheet 5A It was believed that the breakout was a result of open base cover soils and uphill gas vent construction present at this stage of construction which were allowing infiltration of precipitation into the waste as well as the release of leachate to the surface Restrictive layers in the waste mass may have also prevented downward movement of the leachate thus allowing lateral flow of leachate The situation was an interim condition of the construction sequence which would be eliminated by completion of the cap and removal of the infiltration recharge

To address the situation on September 30 1997 wastes in the area of the seep were excavated and the excavation filled with crushed stone The objective was to prevent the breakout of leachate until subsequent construction of the cap could occur This created a very permeable zone within the waste mass allowing the leachate to remain within the waste Observation of the seep area after replacement of the base cover soil indicated the work was effective for the intended purpose

719 Sediment Basin

A Sediment Retention Basin downhill of the landfill work provided the capture of sediment laden runoff water from a majority of the site under construction No outlet structure was operated during the construction work thus allowing no release of water from the basin In time significant amounts of sediments and water accumulated in the basin

Starting September 30 1997 a pumping operation commenced to lower the water level and provide access to remove the sediment accumulation Water was initially pumped to WRA C and allowed to flow overland through the forest Observations of the flow were made and the pump operation sequenced to prevent the pumped water from entering Sandy Brook This discharge location required cycling the pump on and off to regulate the discharge flow The quantity of water removed from the basin was not sufficient to lower the basin water level

An alternative solution was implemented Construction of an earthen berm within the on-site borrow pit to provide an alternate storage basin for the sediment laden water ensued A perforated riser pipe outlet structure with sealed outlet holes was also installed in the borrow pit Water was then pumped from the sediment basin into the borrow pit basin This approach allowed complete removal of water from the sediment basin With the sediment basin emptied of water sediments were removed to restore the design elevations for the bottom of the sediment basin The outlet structure was installed on the sediment basin after the sediment removal to provide the ultimate design intent of the sediment basin

On November 4 1997 the Contractor began pumping the silty water from the Sediment Retention Basin to the on-site borrow pit Within hours after the pumping began it was discovered that some of this pumped water was exiting the pit through a breach in a small berm and traveling approximately 1500 feet before reaching Sandy Brook at a location approximately 2000 feet south of the of the landfill site 1000 feet

9606401 32 ~ OJ1299 Saco F-CERT 02-99 Ildoc

downstream of the confluence of Big Ledge Brook and Sandy Brook As soon as this problem was discovered corrective action was taken The pump was immediately turned off and a larger earthen berm was built to contain the water being pumped to the borrow pit

The water removed to the borrow pit basin remained within the pit basin for approximately 90 days to promote settling and clarification of the water At the end of the period the water was tested to verify compliance with ambient water quality standards The outlet structure holes were opened March 7 1998 to allow controlled discharge of the water By May 1998 the pit basin was empty At this time the containment berm was leveled the outlet structure was removed a riprap outlet channel constructed and the surface stabilized with vegetation


The design termination of the landfill cap was modified to accommodate conditions encountered during the work These conditions being a lack of sufficient elevation difference along the northerly side of the landfill to allow the drainage layer to daylight into perimeter drainage channels an installation of the barrier layer which did not allow the riprap drainage zone to be installed at the appropriate location within the termination and bedrock outcrops which abut the termination and were not anticipated during design Each of the conditions was addressed by CWDs and were characterized as major changes because of the substantial revisions required in the design of the cover termination to accommodate the conditions encountered

Change in Work Directive 13 revises landfill grades for the cover termination on the northerly side of the cover It also includes the installation of drainage pipe extending beneath the access road to a discharge location on the north side of the road A clean out for the pipe is positioned on the southerly side of the road west of Culvert 2 inlet

Further revision of the cover termination detailing is presented in CWDs 14 14A 14B 14C 14C revised 23 23A 28 and 30 as presented in Appendix B2 - Change in Work Directives A Termination Detail Summarj Table indicating the stationing for each termination detail appears on Plan Sheet 8 A of Appendix B5 - Record Drawings hile Plan Sheet 5A contains the perimeter stationing of the landfill referenced within the table

7111 Barrier Soil Repair

On September 22 1997 it as observed that the installed geomembrane in Work Area 1 approximately 60 feet uphill of Gas Vent 18 vas damaged The damage consisting of a short tear in the geomembrane apparently occurring from equipment being used to place the drainage sand above the geomembrane

On September 25 1997 work was performed to uncover the geomembrane and determine the cause and extent of the damage The location of this work is shown on the Appendix B5 - Record Drawings sheet 5A Upon removal of the drainage sand surrounding the tear the surface and the underlying barrier soil were observed to have been deformed into ridges valleys and humps The tear in the geomembrane occurred in an area of a hump Upon observing the deformed surface concern developed as to whether the condition was the result of equipment or a slope failure Removal of the geomembrane was necessary to further examine the area and attribute cause

9606401 33 051299 Saco F-CERT 02-99 II doc

On October 3 1997 the geomembrane above the deformed barrier soil surface was slit open in an H pattern approximately 66 feet long by 35 feet wide and the flaps folded back Upon geomembrane removal it appeared the barrier soil was disturbed by equipment movement and not slope failure This determination resulting from the appearance of parallel ruts similar to what could result from tracked equipment Further exploratory work consisted of excavating the barrier soil in the disturbed region Via the excavation observation of the gas transmission sand-barrier soil interface showed no sign of disturbance or water seepage thus eliminating slope failure or leachate seepage as a possible cause What was observed was a change in the thickness of barrier soil layer from its initial installation and pockets of soft barrier soil located within the second lift of placement From observation of soil conditions it appeared that the second lift of soil had insufficient shear strength to support the equipment operating above The first and third lifts of barrier soil did not exhibit the softness From these observations it was determined that the equipment placing the drainage sand had caused movement of the soft soil pockets within the second barrier soil lift

Repair to the affected area consisted of the removal of all the second and third lifts of barrier soil and most of the third lift within the repair area The removed soil lifts were sequentially replaced with new barrier soil from the Cole Dairy- pit Each lift was individually placed compacted and tested Work to finish the repair consisted of seaming and testing the geomembrane on October 7 1997

Inspection of the barrier soil surface of Work Area 3 found areas where rutting was caused by the tires of the compaction equipment Although the surface was firm it was suspected that the first or second lifts of barrier soil exhibited similar softness described above In order to avoid the condition experienced in Work Area 1 seven discrete areas of soft soil in Work Area 3 were removed and replaced with new lifts of barrier soil obtained from the Cole Dairy pit The specific locations of soil replacements were not recorded

7112 Winter Construction Shutdown

Construction of the NTCRA design continued until December 23 1997 at which time work was suspended for the winter The level of work completed to this date was intended to achieve Substantial Completion

7113 Substantial Completion Inspection amp Punch List

Site inspections for substantial completion were performed by Woodard amp Curran on December 19 1997 by the MEDEP on December 11 16 18 and 19 1997 and by TRC Environmental Corporation on December 18 and 19 1998 Woodard amp Curran presented their inspection findings to the EPA via a December 29 1997 letter submission The MEDEP summarized their inspection findings via a January 15 1998 memorandum while TRC Environmental presented their inspection findings in the Monthly Summary and Substantial Completion Inspection and a technical memorandum both dated January 9 1998

The findings of the three individual substantial completion inspections were combined into a tabular format Punch List indicating the remaining design issues remaining work and non-conformances encountered during these inspections This punch list appears in Appendix F - Punch List

7114 Work Performed for Completion

Commencing in May 1998 the Contractor completed work on the landfill by performing corrective work of non-conformances identified in the substantial completion inspection in December of 1997 and punch list Corrections to the finish grade were performed on the top of the landfill and on its southeast comer the cover termination at Station 19+75 was brought into conformance with the specifications sediment was cleaned out of the slope benches and other miscellaneous items identified in the punch list were corrected The Contractor completed all of the punch list items On June 19 an inspection of the repairs and clean up activity revealed that additional work was required to complete the project This additional work was performed in July 1998

7115 Final Inspection

Pre-final inspections were performed by the EPA on July 30 1998 and MEDEP on July 17 1998 The principal purpose of the inspection events were to identify any remaining issues to enable corrections or modifications prior to the final inspection of August 27 1998

The Maine DEP inspection on July 17 1998 resulted in a Punch List with 20 items of non-conforming work The Pre-final inspection conducted by EPA on July 30 1998 resulted in a Punch List by TRC Environmental with 14 items The majority of these items had been completed by the final completion date of August 27 1998 At a final inspection on August 26 and 27 the EPA and Maine DEP prepared a Punch List with nine items and the completion date vas extended until September 3 1998 The first two items in this final Punch List described the general non-conformance conditions in the slope benches and a detailed list of 26 locations was prepared by Woodard amp Curran The Punch List items from all of the lists were completed by the deadline Correspondence relating to the final inspections and acceptance are included in Appendix F

72 NON-CONFORMANCES

Each component of the construction was considered to be a non-conformance until construction quality assurance procedures determined that materials or completed work conformed to the design requirements shown on the plans and as specified including approved changes Individual qualifying factors to address those non-conformances which were not addressed by change rework replacement or correction follows

721 Base Cover Soil Sample 240

During progression of the work the grain size of base cover soils were observed to be somewhat different than the specification requirements This issue was addressed by revision of the specification by way of Change in Work Directive 7 which appears in Appendix B2 - Change in Work Directive

Base cover soil sample 240 is identified as a non-conformance issue due to its gradation Acceptance for certification of this item is based upon the required performance standard of an unclassified fill material transmissive to gas providing a suitable subgrade for cover construction

722 Geomembrane Installation

As indicated in Section 5 the specific non-conformance issues of geomembrane installation and their resolution are addressed by GeoSyntec Consultants appearing as Volume 5 of this document GeoSyntec Consultants performed a review of the JampL Engineering report conducted a supplemental data collection program and presented their findings

The identified geomembrane non-conformance issues and their resolution are summarized below

7221 Trial Welding

Geomembrane trial welding was not performed in strict conformance with the project specifications The times between trial welds occasionally exceeded the maximum of 4 hours and several tests did not include a test for parent material strength In these cases the manufacturers published minimum strengths were used to accept the test weld Because it appeared that test welds were performed and documented on all days that geomembrane was welded and since the data did not show serious problems with the machine performance the test welds met the intent of the CQA Plan

7222 Seam Welding

Documentation of seam welding was missing for 12 of the more than 145 seams on the project This is addressed by the supplemental testing program by GeoSyntec Consultants

7223 Non-Destructive Tests

Non-destructive testing of production seams was not documented clearly for over 15 of the seams This is addressed by the GeoSyntecs supplemental testing program

Ten of the non-destructive seam tests were performed at pressures lower than specified Since the pressures were not excessively low and destructive tests at two of the seams tested at low pressures were destructively tested the pressure tests met the intent of the CQA Plan This issue is also addressed by the supplemental testing program by GeoSyntec Consultants

One non-destructive test had a pressure drop of 4 psi instead of the specified maximum of 3 psi This seam was tested at a pressure of 32 psi instead of the specified 18-25 psi so the percentage pressure drop was less than the normal allowable percentage The seam was also destructively tested The seam is considered to be acceptable

7224 Record Drawing

The Geomembrane Record Drawing does not show the locations of the repairs and patches as specified Since an accurate survey was not specifically required the data was not available to show on the record drawing The locations are generally noted in the Repair Log documentation The location of the large geomembrane repair required for re-working the barrier soil is shown on the construction record drawing The record documentation is considered to be adequate

9606401 36 051299 Saco F-CERT 02-99 Ildoc

723 Gas Sand Sample 127

Gas sand sample 127 had a hydraulic conductivity of 000098 cmsec which is slightly less than the 00010 cmsec specification value

The source testing program for gas sand was intended to evaluate a soil source and determine where the acceptable soil was within the source and to determine if any or all of the proposed soil source would meet specifications TRC EnvironmentaFs Technical Memo (Draft) of July 22 1997 which reviewed the soils source test data provided to EPA acknowledged that sample 127 would be unacceptable for the intended purpose and states Material from this location is marginal at best and should be avoided Project documentation shows that marginal material within the source pit was avoided Subsequent testing of the installed gas sand indicates that material conforming with specified hydraulic conductivity requirements was provided All other samples 13 of 13 tests performed on delivered in-place soil met specified requirements

724 Barrier Soil In-Place Test 533

Test 533 was a field moisturedensity test taken on the second lift of the barrier soil on September 19 1997 The test is a failed test of moisture content dry without retest and is a non-conformance The previous and following tests 532 and 534 indicate conformance of the soil being installed in a corresponding time frame This one test has been addressed as an outlier

725 Select Borrow In-Place Tests 1058 1071 1112 1115

These four tests were individual field moisture density tests taken over a period of three weeks that failed to meet the minimum requirement of 90 percent compaction and are in non-conformance with the specifications The tests respectively have compaction of 891 899 893 and 894 percent when referenced to the proctor curve 430 having a maximum dry density of 1134 pcf Where each proctor test represents 5000 cubic yards of installed material it is anticipated that within this soil volume there is natural variation of maximum dry density There were eight different proctors used for the select borrow material with a range of maximum dry densities from 986 pcf to 1180 pcf with a mean maximum dry density of 1094 pcf Using the mean maximum dry density for computing percent compaction of these four tests the tests exceed 92 compaction and are within the specifications

726 Cover Termination Station 13+50

A pre-final inspection identified that the pipe outlet from the cover termination near station 13+50 was not built in a manner that was in strict conformance with the cover termination detail required at this location The non-conformance was caused by the pipe outlet projecting through the riprap perimeter strip above the typical detailed location at the bottom edge of the riprap It should also be noted that the cover terminates into a wetland within this general area

After the inspection a corrective action was performed to lower the pipe outlet to the bottom edge of the riprap band to achieve conformance with the cover termination detail This correction at the pipe outlet also caused the pipe outlet to be slightly below the ground surface associated with the adjacent wetland Hence correction of the non-conformance had introduced a performance issue of drainage away from the

9606401 37 051299 Saco F-CERT 02-99 Ildoc

lowered pipe end To provide positive drainage a small parabolic swale was excavated from the pipe outlet to the adjacent wetland

727 Sediment Retention Basin Outlet

The sediment retention basins outlet riser pipe has four two inch diameter dewatering orifice holes near the base Item number 14 on a MEDEP inspection memo of July 17 1998 identified these uncovered holes as a non-conformance Although outlet flow performance with the use of the stone over the dewatering holes has not taken into account within the design documentation a graded crushed stone layer has been placed over the dewatering holes in response to this MEDEP finding of non-conformance

728 Slope Bench Channel Grade

During the Final Inspection of August 27 1998 Channel C was observed to have changes in grade with one location appearing flatter than other segments Subsequent survey of the channel grade located approximately a 70-foot length of channel with a 21 center line grade with steeper grades above and below this channel segment

Acceptance of the channel slope has its basis in the Design Report May 30 1997 which states the 2 is adequate for the cross slope drainage provided by the slope bench

729 Topsoil Organic Matter

Testing of topsoil organic matter content yielded results which were below the 6 specified This is a non-conformance caused by the testing procedure employed and not the material itself

Topsoil organic matter content can be measured by various laboratory methods (eg weight loss on ignition dichromate oxidation colorimetric determination and others) and the percentage of organic matter present within the soil reported by each test method will be different The project specifications did not address which test method to use for organic matter content measurement Therefore it was necessary to determine if the results of the test methodology used indicate sufficient organic matter to support vegetation

The particular laboratory used for testing organic matter performed a loss on ignition (LOI) test of only the organic material which passed through a 2 mm sieve From discussions with the testing laboratory total organic matter content without sieving of the sample would be much greater because the composts organic matter has a discernible component of particles larger than 2 mm In addition to sieving the samples to remove larger organic matter particles the LOI test result was then converted to a Walkley-Black equivalent organic matter using the regression equation organic matter = 104 x LOI -10

The topsoils organic matter content has been accepted based on the knowledge that the testing method removed the organic matter particles larger than 2 mm (of which there were many because of the compost material) and because conversion of the LOI result by empirical equation involved further reduction of the result by approximately 1

8 DEMONSTRATION OF COMPLIANCE

In May 1997 an Administrative Order By Consent for Removal Action (US EPA Region 1 CERCLA Docket No CERCLA-I-97-1009) the Order was signed to allow implementation of the removal action at the Saco Municipal Landfill site The Order required submittal of a Demonstration of Compliance and Removal Action Report to document that all of the performance standards and other requirements of the Action Memorandum and Statement of Work (excluding the Post Removal Site Control and the Long Term Monitoring) have been achieved by the implementation of the NTCRA This Completion of Removal Action Report is to fulfill the requirement

81 NTCRA PERFORMANCE STANDARDS

The performance standards for the NTCRA are specified in the Action Memorandum and Statement of Work The performance standards include

bull Sediment Excavation and Consolidation bull Consolidation of Solid Waste bull Landfill Cap bull Surface Waters bull Air bull Long Term Monitoring bull Post Removal Site Control bull Institutional Controls

Table 8-1 summarizes these performance standards their requirements as contained in the Removal Action Statement of Work and the actual condition that achieved these standards The documentation for achievement of these standards is contained within the descriptive text and appendices of this Completion of Removal Action Report

82 APPLICABLE OR RELEVANT AND APPROPRIATE REQUIREMENTS

Applicable or Relevant and Appropriate Requirements (ARARs) are federal and state human health and environmental statutes and regulations used to evaluate the appropriate extent of site cleanup scope and formulate removalremedial action alternatives and govern the implementation and operation of a selected removal or remedial action Although Congress did not in the 1986 amendments to CERCLA require EPA to meet ARARs during removal actions (Preamble to Final NCP 55 FR 8695 March 8 1990) EPAs policy as established in the National Contingency Plan has been to require that removal actions attain ARARs to the extent practicable considering the exigencies of the situation (40 CFR 300415(i)) Section 30 of the Engineering EvaluationCost Analysis for the Saco Municipal Landfill site identified the potential ARARs for the proposed removal action Based on this information the USEPA identified in Appendix X to the Action Memorandum the ARARs to be attained as part of this project These ARARs are presented in Tables 8-2 through 8-4 along with a synopsis of the requirement the activities to be conducted to comply with each ARAR and the activities that were conducted to ensure compliance with each ARAR
