I. Introduction

1.1 General

On October 27, 2000, a Consent Decree (CD) executed in 1999 by the General Electric Company (GE), theUnited States Environmental Protection Agency (EPA), the Massachusetts Depament of EnvironmentalProtection (&WEP), and several other government agencies was entered by the United States District Court forthe District of Massachusetts. The CD governs (among other things) the perfomance of response actions toaddress polychlorinated biphenyls (PCBs) and other hazardous constituents in soils, sediment, and groundwaterin several Removal Action Areas (RAAs) located in or near Pittsfield, Massachusetts that are included withinthe GE-PiltsfieldiWousatonic River Site (the Site). For each Removal Action, the CD and accompanyingStatement of Work for Removal Actions Outside the River (SOW) (Appendix E to the CD) establish PerformanceStandards that must be achieved, as well as specific work plans and other documents that must be prepared tosupport the response actions for each RAA. For most of the Removal Actions, these work plansldocumentsinclude the following: Pre-Design Investigation Work Plan, Pre-Design Investigation Report, ConceptualRemoval DesignRemoval Action (IUl/RA) Work Plan, and Final R D M Work Plan.

This Pre-Design Investigatiorz Work Plan for East Srt-eet Area I -Nortlz (PDI Work Plan) describes the soilinvestigations proposed by GE to support the evaluation and design of soil-related response actions for the EastStreet Area 1-North RAA, one of several RAAs that comprise the "GE Plant Area" under the CD. The results ofthese investigations, in combination with usable information from prior investigations within East Street Area 1-North, will support the development of a Conceptual RDRA Work Plan. Following EPA approval of thatdocument, GE will then prepare a Final RDiRA Work Plan for this Removal Action.

This PDI Work Plan includes a summary of available soils information related to East Street Area I-North, anassessment of the adequacy of this information to characterize this area (relative to the soil investigationrequirements established in the CD and SOW), and a proposal for additional soil investigations. Although theCD and SOW establish Performance Standards for response actions relating to soil, groundwater, and non-aqueous-phase liquid (;"I'APL), this PDI Work Plan focuses only on soils. Response actions related togroundwater and NAPL at East Street Area I-North are being addressed separately as part of activities for thePlant Site 1 Groundwater Management Area (GMA 1) pursuant to the CD and SOW. At the present time, theseactivities consist of the performance of a baseline monitoring program in accordance with GE's Baseline~Zrlbnitoring Program Proposal for Plant Site I Groundwater finagenzent Area, as conditionally approved byEPA.

It should also be noted that certarn existing areas and bulldings wthin the CE Plant Area are included m anagreement b o r n as the Definitive Economic De~elopment Agreement (DEDA) executed by GE, the City ofPiMsfield, arid the P~tlsfield Economic Development Aut-horiv (PEDA) refatmg to the redevelopment of certainareas of GE's P~ttsfield facility. Under the DEDA, GE will demolrsh the above-gade portrons of the exist~ngCE-otvned building in East Street Area I-North (Building 69). Foflowrng demoltt~on of Bu~ldlng 69, theexrst~ng floor slab and subsurface bu~ld~ng foundatton wrll remam. As such, for the purposes of the GD, SOW,and th~s PDI Work Plan, the foo"ipnnt of Building 69 wd'l be eonsldexed a paved area and fle sorIs underlymgthe buniding wrll "o subject to pre-des~gn so11 lnvesbgaaons consrstent with the requnements esbbl~shed for GE-owed paved areas at the GE Plant Area.

2. Background Information

2.1 General

Tlxs section of the PDI Work Plan provides a general summary of information concerning East Street Area 1-Worth, with an emphasis on the soil analytical data available from prior investigations perfomed by GE in thisarea. Section 2.2 describes the physical boundaries and site features of East Street Area 1-North, while Section2.3 summarizes the prior soil investigations and available soil analytical data. Several tables and figures areincluded in this PDI Work Plan to supplement the information presented in this section.

2.2 Description of East Street Area 1 -North

East Street Area 1 -North occupies an area of approximately 5 acres and is located immediately south of the EastStreet Area 2-North RAA and east of the 20s Complex. This area is generally bounded by a non-GE-ownedrailway property and right-of-way to the north, Merrill Road to the west, East Street to the south, and a non-GE-owned commercial area to the east (Figure 1). East Street Area 1-North is located outside of the ZOO-yearfloodplain of the Housatonic River, Silver Lake, and Unkamet Brook.

As shown on Figure 2, there are seven separate tax parcels (as well as certain adjacent City-owned roadeasements andor rights-of-way) within East Street Area 1-North. The separate parcels consist of the following:

• Parcel J10-8-1;• Parcel J10-8-2;• Parcel J1O-8-3;• Parcel J1 0-8-4;• Parcel J10-8-5;• Parcel 510-8-6; and• Parcel K10-14-1.

Pursuant to the CD and SOW, all of East Street Area 1-North is considered a "commercial/indushia17' area. Ofthe parcels identified above, the first six are owned by GE and the remaining parcel (Parcel K10-14-1) is ownedby another private party. Present within Parcel K10-14-1 is an existing structure that extends onto a portion ofGE-owed property; the portion of the structure located on GE-owned Parcel 510-8-6 is referred to as Building69. The area to the west of this structure (owned by GE) is unpaved, while the area to the east of the structure(non-GE-okwed) is mostly paved, as show on Figure 2. The GE-omed property also contarns a NAPLcontarnmentirecovery system, referred to as the East Street Area 1 Norths~de Recovery System.

2.3 Summary of Available Soil Analflical Data

Pnor to executrng the CD, the area cmmtly referred to as East Street Area I -Nonh was part of a larger areaknokvx as East Sbeet Area IiljSEPA Area 3. Revlous sod investlgatrons focused on the larger East Street AreaIKSEPA Area 3; however, for the purposes of &is PDl Work Plan, only data obtained from withm East StreetArea l -P.;ofih have been cons~dered and sumanzed In th~s sectlon.

Begiming in the early 19XOs, several soil investigations have been conducted within East Streel Area 1-Hodh.These included mvestigations conducted by GCE in the 1990s pursuant to an Adm~nzstrative Consent Orderexecuted in July 1990 by GE and h4DEP andor a Resoufce Conservation and Recovery Act (RCR.1) CorrectiveAction Pennit issued by EPA to GE effective in Januav 1994.

hformation concerning East Street Area 1-Korth and, in particular, the results of the prior soil investigarionshave been presented in numerous documents submitted by GE to EPA andor MDEP. Certain of thesedocuments include sumaries of earlier existing data. The primary documents that provide such informationinclude:

• East Street Area 1 MCP Phase I1 Supplemental Data Sztmma~ Blasland & Bouck Engineers, P.C., May1990;

• Inrerim Phase If — Comprelzensive Site Assessment/Current Assessment Stimmary Report for East StreetArea INSEPA Area 3, Geraghty & Miller, November 1991;

• MCP Interim Phase 11 Report and Current Assessment Summaly for East Street Area I/USEPA Area 3,Blasland, Bouck & Lee, Znc. (BBL), October 1994;

• Addendum to MCP Supplemental Phase 11 Scope of Work and Proposal for RCRA Facility Investigation ofEast Street Area I/ USEPA Area 3, Golder Associates, November 1996.

The investigations previously performed by GE that are described in the reports listed above have resulted in thecollection of 34 soil samples (including duplicates) for PCB analysis &om or adjacent to this RAA. h addition,5 soil samples (including duplicates) collected from this RAA during prior investigations have been analyzed forone or more groups of non-PCB constituents listed in Appendix LX of 40 CFR Part 264, plus three additionalconstituents (benzidine, 2-chloroethyl vinyl ether, and 1,2-diphenylhydrazlne) (Appendix IX-t-3). Figure 2illustrates the prior sampling locations and includes (on that figure) tabular summaries of the resulting PCB data.The soil sampling locations and depths previously sampled for PCBs are also listed in Table 1. The soilsampling locations and depths previously sampled for non-PCB Appendix Dli.3 constituents, along w~th the~oups of such constituents that were analyzed for, are listed in Table 2. The analytical results from thesesamples for both PCBs and other Appendix LX+3 constituents are presented in Appendix A in tables from priorreports.

Subject to certain conditions, the CD and SO%V allow the existing soil data to be incorporated into the pre-design soil investigations for East Street Area 1-North. Section 4.3 of this PDI Work Plan describes the processby sYhrch these data were emluated for usability and, if appropriate, ~ncluded m the development of theproposed pre-des~gn investigations.

3. Applicable Performance Standards and RelatedRequirements

3.1 General

This section summarizes the Perfomance Standards established in the CD and SOW that are applicable to theEast Street Area 1-North soils, as well as the applicable pre-design soil investigation requirements.

3.2 Soil-Related Performance Standards

Response actions for soils at East Street Area I-North must achieve the relevant Performance Standardsincluded in the CD and SOW for the GE Plant Area. The Performance Standards established for soils at the GEPlant Area, including East Street Area $-North, are set forth in Paragraph 26 of the CD and Section 2.2.2 of theSO%'. In general, the need for and extent of response actions to address PCBs and non-PCB Appendix IX+3constituents in soils are to be determined based on the available soils data and using evaluation proceduresestablished in the CD and SOW.

For PCBs, response actions are to be based on the results of spatial averaging conducted for soils at East StreetArea I-North. Attachment E to the SOW identifies the averaging areas, the methods to be used to determineexisting spatial average PCB concentrations, and the procedures to be used to assess whether the anticipatedresponse actions will achieve the PCB Performance Standards. For non-PCB Appendix IX+3 constituents insoils, the evaluation is to address the same areas evaluated for PCBs, to take into account the response actionsnecessary to address the PCBs, and to be conducted in accordance with the protocols described in Attachment Fto the SOW. For both PCBs and other Appendix 0(+3 constituents, there are two averagingievaluation areas atEast Street Area 1-North - one consisting of the GE-owned portion and the other consisting of the non-GE-owned property. (For purposes of this PDI Work Plan, the areas described as the GE-owned portion and thenon-GE-owned property are considered to include the adjacent City-owned road easementsirights-of-way exceptwith respect to property ownership considerations.)

The applicable Performance Standards for PCBs in soils at East Street Area 1-North are summarized below:

For the GE-owned portion of East Street Area I-North, GE shall conduct the following response actions asneeded based on the results of PCB spatial average calculations:

• For the unpaved portion of this area, if the spatial average PCB concentration in the top foot exceeds 25parts per million @prnj, GE shall either remove and replace soils or install a soil cover 1x1 accordance withthe specifications for soil covers descri'oed in Atzachent G of the SOW as necessary to aeh~eve a spatla1average PCB concentration of 25 ppm or less. Zn addifion, srnce this ent~re area will constlrute a singleaveraging area in excess of I a m in slze, GE shall remve any so~ls conta~n~ng PCB concentsations greaterthan 125 ppm tiom the top foot m this mpaved portion.

• For the entire area — including both the unpaved pomon and the slab at Bulldmg 68 (wh~ch will beconsidered a paved area) -- if the spatial average PCB concentration in the top foot exceeds 25 ppm, CEshall recalculate the spatla1 average PCB coneenkation for the top foot after incorporat~ng the anticipatedperfamnee of the response actions described above for the unpaved portion. If that recalculated spatial

average PCB concenh-ation still exceeds 25 pprn, GE shall maintarn and enhance the existing concrete slabsurface in those areas of the slab detemined to cause the exceedance of the 25 ppm spatial averageconcenwation for the top hot in the entire area. Such enhancements will be in accordance with thespecifications described for pavement enhancement in At-Tachment G of the SOW.

• If the spatial average PCB concentration in the 1- to 6-foot depth increment in the entire area exceeds 200ppm, CE shall undertake a combination of removal and replacement of soils in the unpaved portion andlorenhancement of the existing concrete slab surface in the paved area (in accordance with the specificationsfor pavement enhancement in AMachment G of the SOW) as necessary to ensure that the PCBconcentrations causing the spatial average to exceed 200 pprn are removed or covered by enhancedpavement.

• If, after incorporating the anticipated performance of response actions in accordance with the foregoingPerformance Standards, the spatial average PCB concentration for the 0- to 15-foot depth increment exceeds100 ppm, GE shall install an engineered barrier either over the soil (in the unpaved portion) or over theconcrete slab (in the Building 69 area) in accordance with the specifications for engineered barriers inAttachment G of the SOW.

• Where utilities potentially subject to emergency repair requirements are present and the spatial average PCBconcentration for the soils in the utility corridor that may need to be removed during an emergency repairexceeds 200 pprn in the 1- to 6-foot depth increment, GE shall evaluate whether additional response actionsare necessary for that corridor and submit that evaluation, and a proposal for such response actions ifneeded, to EPA. In addition, if a new subgrade utility is installed or an existing subgrade utility is repairedor replaced in the future, GE shall ensure that the spatial average PCB concentration of the backfill materialdoes not exceed 25 ppm.

For the non-GE-owned property within East Street Area 1-North (i.e., Parcel K10-14-I), GE shall make "bestefforts" (as defined in the CD) to obtain a Grant of Environmental Restriction and Easement (ERE). If an EREcannot be obtained, GE shall implement a Conditional Solution in accordance with Paragraph 34 of the CD.The applicable Performance Standards for PCB response actions at this property depend on whether an ERE isobtained or a Conditional Solution will be implemented. Those Performance Standards are as follows:

If an ERE is obtained:

• If the spatial average PCB concentration in the top foot in the unpaved portion of this property exceeds 25ppm, GE shall remove and replace soils as necessary to achieve that spatial average PCB concentration. Inaddition, GE shall remove any soils containing PCB concen&ations greater than 125 ppm in the top foot ofthis unpaved portlon.

• If the spatla1 average PCB concentration in the top foot in the paved porrion of this property exceeds 25ppm, GE shall eitha remove and replace soils as necessary to achie~e that spat~al average concenh.ation orenhance the exlsting concreteiasphalt surface m accordance with the spec~fications for pavementenhancement in Ateachment G to rhe SOW,

• If the spatial average PCB concentrat~on in the I - to 6-foot depth xncrernent at this property exceeds 200ppm (eons~denng the paved and unpaved portions rogether), GE shall remove and replace soils as necessavto achieve that sparial average PCB coneentratlon.

• If the remaining spatial average PCB concentration In the top 15 feet of soil exceeds 100 pprn (afterincorporating the anticipated perfomance of any response actions for the top foot and 1- to &foot depthincrement), GE shall install an engineered barrier in those areas detemined ro cause the excecdance of the100 pprn spatial average concentration.

• %%ere utilit~es potentially subject to emergency repair requirements are present and the spatial average PCBconcentration for the soils in the utility corridor that may need to be removed during an emergency repairexceeds 200 ppm, GE shall evaluate whether additional response actions are necessary for that corridor andsubmit that evaluation, and a proposal for such response actions if needed, to EPA. In addition, if a newsubgrade utility is installed or an existing subgrade utility is repaired or replaced in the future, GE shallensure that the spatial average PCB concentration of the backfill material does not exceed 25 ppm,

If aiz ERE is not obtained:

• GE shall conduct response actions as necessary to meet the same Performance Standards described above,except that GE must remove and replace soils as necessary to meet a spatial average PCB concentration of25 ppm in both the top foot and 0- to 3-foot depth increment.

• GE must also meet the other conditions for a Conditional Solution specified in the CD.

The CD provides, in Paragraph 56.b, that GE must notify EPA and MDEP at the time of submittal of the PDIWork Plan for a given Removal Action, or within such other time as is proposed by GE and approved by EPA,whether each person who owns or controls a non-GE-owned property within that RAA agrees to execute andrecord an ERE on the property. As documented in a February 15, 2002 letter from GE to EPA, EPA agreed thatGE's written ERE notice for East Street Area I-North will be submitted one month after submission of the Pre-Design Investigation Report for this M , or at such other time as is proposed by GE and approved by EPA atthe time of submission of that report.

3.3 Pre-Design Soil Sampling Requirements

To achieve the Performance Standards discussed in Section 3.2 above, Section 2.2.3 and Attachment D to theSOW establish specific requirements for soil sampling at the GE Plant Area within the GE-Pittsfield'HousatonicRiver Site. Those that are applicable to East Street Area 1-North are summarized below.

For the CE-owned portion of this RA4, the applicable pre-design soil sampling requirements for PCBs differbetrveen unpaved and paved areas. For unpaved areas, the SOW requires the perfbmance of a grid-basedsampling program, taking into account the existing, usable PCB data. Specifically, the SOW requires thecollection of sudace and subsurface soil samples on an approximate 100-foot p d sampling pattern, withsamples to be collected Corn the 0- to I-, I- to 6-, and 6- to 15-foot depth miervals. For paved areas, soilsampling and analysis must be conducted at an approximate frequency of two locations per acre, with aneaphasis on those areas wlth t~rnited or no exrsting data. At each of these sampling locat~ons, soil samples areto be collected from the same depth intewals as in unpaved areas, to the extent pract~cable given the cond~tronsin the area. As prec-iously discussed, the so11 beneath the area oecupled by the GE-owed Building 69(scheduled for future demolition) will be treated as a paved area for the puposes of this PDI Work Plan,

For the non-CE-owed property tvithin thts RAA (Parcel K1 8-1 4-11, the SOW does not set out any drfferenr so11sampi~ng requiremen& &om those specified for the remainder of East Street Area 1 -North. However, due to thenon-GE owership of this property and current uncerta~nties regarding whether an ERE w1l1 be obtained for the

BLASLANT;, BOUCK & LEE, ING.

5,22B2 engineers & scientists 3-3\\BBL_DOCS\VOLI\GEWiE_Pittifield_CD_ESA_l_Nonh\Reponj and Prcsentaions\3302i99.doc

property, GE believes that it makes sense to sample this property in accordance with the same requirementsspecified in the SOW for non-GE-owned commercial/industrial properties located in the Unkamet Brook Area(which are likewise contained within the overall GE Plant Area under the CD). For PCBs, those requirementscall for the collection of surface soil samples (from the 0- to 1-foot depth increment) on an approximate 50-footgrid pattern and the collection of subsurface samples on an approximate 100-foot grid pattern, with suchsamples to be collected from the 1- to 3-, 3- to 6-, and 6- to 15-foot depth intervals. The soil beneath thebuilding on this parcel is not required to be sampled.

In addition to PCBs, certain soil samples must be analyzed for other Appendix IX+3 constituents. As providedin Attachment D to the SOW, the total number of non-PCB Appendix EX+3 analyses must be approximatelyone-third the number of PCB samples (existing and proposed) needed to meet pre-design investigationrequirements, and must be approximately evenly distributed between surface soil samples (from the top foot ofsoil) and subsurface soils (from the various deeper intervals). The actual selection of sample locations anddepths for Appendix IX+3 analyses is to be based on the spatial distribution of the available data and may bemodified based on field observations at the time of sampling (e.g., photoionization detector [PED] readings,evidence of staining, etc.).

4. Identification of Data Needs and Proposed Pre-Design Investigations

4.1 General

As sumarized in Section 3.3 of this PDI Work Plan, the SOW establishes soil investigation requirements tosupport the perfomance of RD/RA activities and achievement of applicable Performance Standards for soilswithin East Street Area 1-North. This section considers these requirements and the soil data currently availablefrom prior investigations in this area to identify the necessary pre-design soil investigations for East Street Area1-North. Section 4.2 identifies the sampling data needs to satisfy pre-design investigation requirements, andSection 4.3 summarizes the available soil analytical data and provides an assessment of the usability of thosedata to satisfy such data needs. Section 4.4 then describes the additional soil sampling proposed by GE toaddress the remaining data needs, while Section 4.5 summarizes the sampling procedures.

The Data Quality Objective (DQO) for the pre-design investigations is to collect the necessary soil analyticaldata on PCBs and other Appendix IXI-3 constituents to meet the applicable soil sampling requirements specifiedin the SOW, and thus to support future R D M evaluations to assess achievement of the applicable PerformanceStandards for this area.

4.2 Identification of Data Needs

As discussed in Section 3.3 of this PDI Work Plan, the pre-design soil sampling requirements for PCBs at EastStreet Area I-North call for the collection (or availability) of sampling data: (1) on an approximate 100-foot gridpattern in the unpaved portion of the GE-owned area; (2) at a frequency of approximately two locations per acrewithin the area of existing Building 69 (to be considered as a 0.35-acre paved area); and (3) on approximate 50-foot and 100-foot grid patterns at Parcel K10-14-1 (for surface and subsurface soil samples, respectively).Accordingly, the relevant grids were established for the unpaved portion of the GE-owned area and for ParcelKl O-14-1, as shown on Figure 3. In identifying proposed sample locations, grid nodes that fall outside of, butare within 15 feet of, the RAA boundary were relocated to a position within the RAA; and grid nodes that fallwithin the fooQrint of the building on Parcel K10-14-1, but are within 15 feet of the exterior of that structurewere relocated to a position outside the structure. In addition, as d~scussed below, the locations of subsurfaceutilities potentially subject to emergency repair were considered and due to the narrow configuration of thisM , certain sampling Iocations at the GE-omed portion were relocated inward from the precise grid nodes toprovide more representat~ve spatial coverage of the RAA.

Based on the applicable pre-design soil samplmg requirements and the relevant g~ds, and without considwarionof any exist~ng usable PCB sampling data, the pre-design soil invest~gation criteria requrre PCB data from a totalof 78 samples. These Include 30 samples tiom 10 locations at the CE-owned portron of this U 4 and 48samples (27 surface soil samples from 27 locations and 21 subsuface soil samples from seven locations) atParcel K10-14-1. An assessment of the extent to whch the ex~st.tng PCB data can be used to sat~sfy these dataneeds 1s provided in Section 4.3.1 below.

For non-PCB Append~x EX-+-3 constiluents, based on the pre-desrp invesr~gatron reqmrements presented tn theSOW, the number of avatlable Appendix IX1-3 analyses must be approx~mately one-ththnd the number of PCBsamples requzred to charactenze the RAA, w~th these data approximately evenly d~sh-tbuted between the top foot

of soil and vanous subsurface sampling increments. Based on the PCB soil sampling requirements sumanzedabove, this will require approximately 26 samples for Appendix D(+3 analyses. An assessment of the usabiIrtyof the existing Appendix IX+3 data to satis& these data needs is provided in Sectron 4.3.2.

4.3 Assessment of Existing Soil Analytical Data for Usability

The existing soil data for East Street Area 1-North are listed in Tables 1 and 2 (for PCBs and non-PCBconsfituents, respectively) and summaries of the analytical data from those samples are provided in Appendix A.These data have been reviewed to assess their usability to satisfy pre-design investigation requirements and/or tootherwise support future RDirW activities for this area. As provided in Attachment D to the SOW, the criteriafor determining the usability of existing data to support RD/R.A activities include: (I) an evaluation of whethersuch data reflect the appropriate locations and depth increments necessary to meet the soil samplingrequirements specified in the SOW, and to apply the Performance Standards for the Removal Action inquestion; and (2) an assessment of the quality of such data in terms of qual~ty assuranceiquality control. Toperform this review, the existing soil analytical data were reviewed to determine whether and to what extentthey meet the spatial- and depth-related pre-design sampling requirements (i.e., their location and depthincrements relative to the requirements of the SOW). The data were also assessed for overall analytical usabilitybased on several considerations, as discussed below.

4.3.1 Assessment of Existing PCB Data

For the existing soil PCB data set (33 total samples, excluding duplicate samples), the usability assessmentinvolved, at the outset, review of the depth increments from which the samples were taken. This reviewindicated that three sample results are not usable for pre-design or RD/RA evaluation purposes because thesamples were collected from an unspecified depth interval or one specified only as a single depth (i.e., "10feet").

The remaining data, consisting of 30 PCB sample results, were then assessed to determine their overall dataquality and usability to satisfy pre-design investigation requirements and/or in future R D M evaluations. Thisassessment indicated the following categories of PCB data:

• Twenty-four samples were collected and analyzed in 1996. For these data, full laboratory data packages areavailable. These data packages were reviewed for reporting completeness, analytical methodologies, andany apparent methodianalytical discrepancies or other significant data quality issues noted in the datapackages. Review of that documentation showed no deficiencies that would preclude the use of these PCBdata in the response action evaluations for this . Hence, these data are considered usable to satisfy thepre-design investigation requirements (if they meet the specific sampilng requrrements) or, alternately, assupplemental data in future m M activities.

• One PCB sample was collected from just outside this U 4 and analyzed in 1994. For this result, no form oflaboratory documentat~on has been located. Nevertheless, GE proposes to use this result m future m i R devaluations since, based on the other PCB sample results for wh~ch taboratory doeumentatlon has beenrerriewed, there is no reason to klieve t a t this PCB result would not be salfabIe for use in Bf>lWevaiuatrons. However, as a consemative measure, GE w~li only utilize thls result as stlpplemenbl data andnot to satisfy sgecrfic pre-design, sod investtgatlon requirements.

• Five samples were collected and analyzed m f980. For these results, no form of laboratory documentat~onhas been located and the PCB analytical methodology used at that hme was somewhat dtfferent from thecurrent method. Accordingly, these data will not be used to satisfy the pre-design invest~gahonrequirements. However, GE has seen no evldence at the GE-PiMsfieid,Xous&onic R~ver Site that PCB dataanalyzed by the pnor method are significantly different from those analyzed by the current method. Hence,GE may use the 1980 data as supplemental data in future R D M evaluat~ons, subject to further review.

The next step in the assessment was to determine which of the 24 PCB sample results from 1996 could be usedto satisfy the pre-design sampling requirements. First, the sample locations were reviewed in relation to thesampling gnds (and Building 69 area) shown on F~gure 2 (and d~scussed in Section 4.2). Consistent with otherpre-design investigations performed pursuant to the CD and SOW, an existing PCB sample location wasassumed to represent a sample grid node if it is 1oca"ied no more than one-half of the gr~d node spacing from thesample node in question (e.g., an existing sample location that is within 50 feet of a grid node was used torepresent that grid node). Further, existing sample depths were assumed to satlsfy a depth interval requirementif the existing depth(s) constitutes 50% or more of the depth requirement. Based on this evaluation, the usableexisting PCB data adequately address the pre-design sampling requirements for seven soil sampleloeationsidepths, as shown in Table 3.

Table 1 provides a summary of the categorization of all prior PCB samples based on their proposed use relatedto pre-design and future R D M activities. Specifically, the prior PCB data are categorized into one of thefollowing three categories:

• PCB data that will be used to satisfy pre-design soil investigation requirements and will be incorporated intofuture R D M activities (designated "Characterization");

• PCB data that have not been incorporated into the proposed pre-design investigations but will be used infuture R D M evaluations (designated "Supplemental");

• PCB data from analyses performed in 1980 that have not been incorporated into the proposed pre-designinvestigations but may potentially be used in future R D M evaluations, subject to fkrther review(designated "Potential Supplemental"); or

• PCB data that have not been incorporated into the proposed pre-design investigations and will not be used inany future RD/R.A activities (designated "Rejected").

4.3.2 Assessment of Existing Data on Nan-PCB Appendix fX+3 Constituents

For non-PCB Appendix lX+3 constituents, data are available from four samples and one dupl~cate sample for allconstituent groups (except pesac~des and herbicides), as summarized m Table 2. These samples were allcollected from depth increments that can be used in the RDRA evaluat~ons for th~s ; however, for pre-design evaluation purposes, the sarnpleiduplicate pair w~ll be considered as one sample. Full laboratorqf datapachges are available for each of these samples. These data packages were rer4ewed for completeness and theanalyt~cal techn~ques used, as well as to ldennfy any apparent d~screpanc~es or other srgnifrcant data qual~~Issues noted by the analyhcai laboratory that would seem Irkeiy to render the data unusable. Thrs revrew of thelaboratory documntat~on revealed no deftc~encies of the rjrpe that, based on GE's prior assessment of s~rniiardata, seem I~kely to cause these data to be rejected; and thus, these data appear to be of acceptable quality foruse in future R D k 4 evaIuat~ons, Accordingly, GE proposes to use these data to satis@ the pre-designlnvesrtgatlon requrrements for non-PCB constituents.

4.4 Proposed Soit SampIing Activities

This section describes the pre-design soil samplmg proposed by GE to satisfy the pre-design investigationrequirements, taking into account the ex~sting data that are usable for these purposes as described in Sectlon 4.3.To assist in describing the proposed sampling activitres, Figure 3 shows the relevant sampling grids, the extentof the paved areas and buildings, the locat~ons of the prior PCB soif samples that will be used to satisfy spec~ficgrid sampling requirements, and the proposed additional PCB soil sampling locations and depths. Figures 4through 6 show, for each relevant depth increment, the locations of the prior Appendix K i 3 soil samplesproposed for use to meet Appendix Ki-3 pre-design chasacterization requirements and the proposed additionalAppendix K+3 soil sampling locations and depths to satisfy such requirements. Table 3 summarizes theexisting and proposed soil sampling locations and depths that will collectively satisfy the PCB pre-designsampling requirements. Table 4 presents an overall summary of the proposed pre-design soil sampling program,listing, on a sample-by-sample basis, the proposed sampling locations, depths, and analyttcal parameters. Asummary of the proposed pre-design activities is provided below.

PCB Sampling. As discussed in Section 4.3.1, existing PCB data ean be used to satisfy the pre-design samplingrequirements for seven soil sample locationsidepths, GE proposes to collect soil samples for PCB analysis at theadditional locations and depths necessary to satisfy the pre-design soil sampl~ng requirements for PCBs. Theproposed sampling locations are shown on Figure 3. Specifically, at the GE-owned area of East Street Area 1 -North, GE proposes to install soiI borings and collect soil samples at or near each of the remaining 100-foot gridlocations in the unpaved portion of this area, plus one location within Building 69. However, due to the narrowconfiguration of the RAA, GE is proposing to adjust some of the proposed sampling locations slightly inwardfrom the grid nodes, as shown on Figure 3, so as to provide more representative spatial coverage of this area. AtParcel K10-14-1, GE proposes to collect surface soil samples at or near each of the 50-foot grid locations and toinstall soil borings and collect soil samples from them at or near each of the 1 00-foot grid locations (in bothcases, excluding the soil under the existing building).

In addition, based on recent discussions with EPA, GE has evaluated the locations of existing and proposed soilsamples in relation to the known locations of existing subsurface utilities within East Street Area 1-North.Based on review of the available mapping (obtained from the City of Pittsfield), most of the utilities in thisvicinity are located within East Street, rather than within this RAA. However, two service connections to thesewer line and I0 service connections to the water main under East Street have been identified within this RAAfrom available mapping and are shown on Figure 3, although one of the water main connect~ons (theeasternmost connection on Parcel KlO-14-1) may no longer exist. This information has been utilized to ensurethat sufficient PCB data will be available to represent the soil in these utility corridors (considered to beadequately represented by data collected within approximately 25 feet on either side of these ut~lltyconnections). In addition to the service connections mentioned above, the possible existence of other subsurfaceutilrt~es will be assessed as part of the initla1 pre-design site actiwt~es, and this assessment may lead tomodificationsiadditions to the program presented herein. Any such changes would be proposed to EPA forapproval.

The proposed PCB samplmg Iocalrons are shown on Frgure 3 and the proposed sample iocatlons and depths areI~sted in Tables 3 and 4. 73-11s sampf~ng effort will consrst of the co'ilection of a total of 71 samples fbr PCBana'iys~s. In the event that slte conditions (e.g., standmgiflowmg water. large trees, subsurface ut~l~t~es, or otherobsmct~ons) prevent sampling at any of the proposed Iocai~ons, the samples m quefhon will be collected asclose to the ongmai locatron as slte condltlons allow.

Sampling for Other Appendix IX+3 Constituents, As noted above, the SOW requires that the total number ofnon-PCB Appendix K+3 analyses for the pre-deslt&n investigat~on must be approximately one-third of the

BIASLAND, BOUCK & LEE, ING

512102 engineers & scientists 4-4\\BBL_DOCSWOLI\GESGE_Piiafieid_CD_ESA_l_North\RqwitniKl PresemationiU302l99.doc

number of PCB samples required to satisfy the pre-deslm investigat~on requirements. Based on the es~aluationof PCB sampling requirements, the total number of PCB samples needed to satisfy the PCB characterizationrequirements is 78 samples. Thus, for non-PCB Appendix K+3 constrtuents, there must be 26 sample analyses.Of these, approx~mately half must come from the top foot of so~l, wrth the remarning samples distributed amongthe relevant subsurface sampling mcrements.

As discussed in Section 4.3.2, the existing Appendix IX+3 data can be used to satis@ four of these 26 requiredsamples. GE proposes to obtain the remaining Appendix LX13 data by collecting new samples for analysis ofAppend~x IX+3 constituents (excluding pesticides and herbicides, as discussed below). For the GE-ownedportion of the RAA, these will include six soil samples from the top foot of soil and three soil samples (total)from the relevant subsurface depth increments (i.e., the 1- to 6-foot and 6- to 15-foot depths). For the non-GE-owned property, GE proposes to collect seven soil samples from the top foot and six soil samples (total) fromthe relevant subsurface depth increments (i.e., 1- to 3-foot, 3- to 6-foot, and 6- to 15-foot depths). U?len thesenew samples are considered along with the usable existrng Appendix IX+3 data, 12 Appendix lX+3 samplingresults will be available at the GE-owed area (six from the top foot and six from deeper increments) and 14 suchsampling results will be available for Parcel K10-14-1 (seven from the top foot and seven from deeperincrements). The locations of these samples are shown, for each relevant depth mcrement, on Figures 4 through6, and the locations and depths of these samples are listed in Table 4.

For samples collected for Appendix IX+3 analyses as part of the pre-design soil investigations, GE proposes toexclude analyses for pesticides and herbicides for the following reasons: (1) in prior sampling and analysisactivities performed at the GE Plant Area, including East Street Area 1-North, with EPA and/or MDEPapproval, analyses for pesticides and herbicides were not required; and (2) the presence of these compounds, ifdetected, would likely be attributable to the application of weed and pest control materials in accordance withtheir intended and appropriate commercial application.

Table 4 lists on a sample-by-sample basis the proposed sampling locations, depths, and analytical parameters.However, the specific locationsidepths of some of the non-PCB Appendix lX+3 samples may be modified in thefield considering PID readings or other observations (e.g., odors or evidence of staining) or if site conditions(e.g., standingiflowing water, large trees, subsurface utilities, other obstructions) prevent sampling at any of thedesignated locations. If such field modifications are made, GE will endeavor to maintain the proper ratio of thenumber of non-PCB Appendix IX+3 analyses at the various depth intervals (e.g., approximately half from thetop foot and half from deeper increments), to the extent practical.

4.5 Soil Sampling Analytical Procedures

The collection and analysis of the soil samples at East Street Area I-North rn.111 be conducted following theprocedures set forth in GE's approved Field Sanzpling PlanlQualifj Assuratzce Project Plan (FSP/QAPP),Spec~fically, the analq-tlcal procedures for the analysis of soil samples wrll be consistent with the EPA-approvedprocedures presented in Table 1 of the FSP,'QAPP. The field procedures w~ll follow the Standard OperatingProcedures (SOPS) presented in Append~ces B through X of the FSPiQAQP.Sot1 samples collected during the East Street Area 1-North prc-deslp ~nvest~gation will ut~hze EPA Method8082 for the analys~s of Aroclor-spec~fic PCBs. Results for PCBs w~ll be reported on a dTy-weight bas~s wrth adeteet~on Iimrt of 0.05 ppm for ail A4roelors,

So11 samples to be analyzed for other Appendix DC4-3 constituents (exeiuding pestic~des and herb~cldes) will beanalyzed foliosqng the methods presented In Table 1 of the FSP/Qx4PP. Sample results will be presented on adry-we~ght bass with detect~on I~rn~ts consrstent wrth those presented m Table 3 of the FSPIQAPP.

Analysis of samples for polychlorinated d~benzo-p-d~oxms (PCDDs) and polychlorinated dibenzofurans(PCDFs) will be perfomed using EPA Method 8290 for samples collected %om the top hot of soil at all areasof this RA4 and Method 8280A for all other samples. Since Method 8290 has lower detection and reportingIlrnits, it will be used for samples from depth increments for which the SOW prescribes lower PerfomanceStandards for PCDDiPCDF Toxicity Equivalency Quotients (TEQs) [~.e., 5 parts per billion (ppb) for the topfoot in commercialiindustrial areas], while Method 8280A is \vhoIly adequate to ensure achievement of thehigher Perfomance Standard set forth in the SOW for subsurface soil at comerctaliindushial areas (20 ppb).PCDDRCDF results will be reported on a dry-weight basis for both total homologues and 2,3,7,8-substitutedcongeners, using sample detection limits consistent with those presented in Table 3 of the FSP/QAPP. Inaddition, total TEQ concentrations will be calculated for the PCDDiPCDF compounds using the ToxicityEquivalency Factors (TEFs) derived by the World Health Organization (WHO) and representing non-detectedcompounds as one-half the analytical detection limit.

Quality control samples (i.e., matrix spikelmatrix spike duplicates, field duplicates, trip blanks, and field blanks)will be collected at the frequency specified in Table 4 of the FSPiQAPP for each sample matrix collected.Tables 4 and 5 of the FSPIQAPP present the quality control criteria and corrective action procedures to befollowed for each of the analytical procedures listed in Table 1 and for field-generated quality control samples.Overall project quality assurance will be ensured by following the procedures specified in the FSPIQAPP forsample collection and analysis, corrective action, and data reporting and validation.

5. Schedule

GE proposes to complete the invest~gatlons described in this PDI Work Plan and submit a Pre-Designhvestigation Report for East Street Area 1-North within 6 months after EPA's approval of this PDI Work Plan,subject to possible changes due to delays in obtaining access permission or weather-related delays. In the eventthat delays to th~s proposed schedule are identified, GE will notify EPA and propose a revised schedule forcompleting the investigations and submitting a Pre-Design Investigation Report. With respect to access, if GE isunable to obtain access permission from particular property owners after using "best efforts" (as defined in theCD) to do so, it will so advise EPA and MDEP and seek their assistance in obtaining such access pursuant toParagraph 60.f(i) of the CD.

The Pre-Design Investigation Report will present the results of all investigations conducted pursuant to this PDIWork Plan. It will also consider the sufficiency of the available data to support RDI'RA activities for thisRemoval Action. If it is determined that further data are needed to support RDRA activities to achieve the soil-related Performance Standards, that report will propose supplemental investigations to fill those data needs and aschedule for performing those supplemental investigations and submitting a Supplemental Pre-DesignInvestigation Report. If GE concludes in the Pre-Design Investigation Report that the available data aresufficient to support RDRA activities for the Removal Action at this RAA, then that report will include aproposed schedule for submission of a Conceptual RD/RA Work Plan for the East Street Area 1 -North RemovalAction.

6. Summary of Anticipated Post-Removal SiteConfro1 Activities

Following the completion of construction activities to implement the necessary response actions, CE willcontinue to inspect, maintain, and monitor the completed actions and to perform repairs and replacement asneeded, so as to ensure that the completed response actions are performing as designed. The specific scope andmethodologies for such inspection and maintenance activities will be detailed m a Post-Removal Site ControlPlan for the East Street Area I -North Removal Action. Such activities will include the periodic inspection andmaintenance of any surface covers installed (e.g., engineered barriers, enhanced pavement), inspection andmaintenance of any ancillary components of the response actions (em&., fencing and warning signs, if any), andrepair or replacement of response actions at areas exhibiting deficiencies or potential problems.

The Post-Removal Site Control activities will be conducted in accordance with the pertinent requirementsspecified in Attachment J (Inspection and Maintenance Activities) to the SOW, except as otherwise proposed inthe specific Post-Removal Site Control Plan and approved by EPA. In addition, inspection reports on theseactivities will be prepared and submitted periodically in accordance with the requirements of Section 4 ofAttachment J to the SO'CV.

2 Other evlstlng sot1 data wtll not be utrlized in support of the pre-destgn sampling requtrements, but may be used tn the

deslgn of the Removal Action (as dtscussed In the text)

3 Shaded depth increments indicate that soil sampiing 1s not requrred

4. Extsttng samples are assumed to represent a grrd node tf they are located less than 50 feet from 100-foot grrd nodes
