Re: Modifications to Leachate Collection System,Building 71 On-Plant Consolidation Area -GE-Pittsfield/Housatonic River SitePittsfield, Massachusetts

Dear Mr. Olson:

I. Introduction

This letter summarizes recent activities conducted by the General Electric Company (GE) regardingmodifications to the existing leachate collection system at the Building 71 On-Plant Consolidation Area(OPCA) in Pittsfield, Massachusetts. As you know, in 1999 GE designed and constructed the first phase ofthe Building 71 OPCA for the consolidation of materials resulting from various removal actions within theGE-Pittsfield/Housatomc River Site. In accordance with a document entitled Detailed Work Plan for On-Plant Consolidation Areas [Work Plan; Blasland, Bouck & Lee, Inc. (BBL), June, 1999], an approximate2-acre area of the Building 71 OPCA was constructed. This area included, among other items, theconstruction of the impermeable base liner system, the leachate collection system, and stormwatermanagement facilities. However, remediation materials generated in 1999 were not actively consolidatedwithin the Building 71 OPCA; instead, with approval from the United States Environmental ProtectionAgency (USEPA), these materials (approximately 9,000 cubic yards) were placed and secured in a temporarystockpile located immediately adjacent to the Building 71 OPCA.

In anticipation of consolidating the existing stockpile materials within the Building 71 OPCA in the next fewmonths (and thus, initiating "active" operations of the OPCA), GE has identified certain modifications relatedto the existing leachate collection system. These activities are primarily related to the existing leachatecollection manhole, including physical changes to the manhole and the installation of the permanent leachatepumps (and related piping, controls, and instrumentation). The remainder of this letter summarizes theseconstruction activities and identifies the anticipated implementation schedule. Although this letter is beingprovided to the USEPA for informational purposes, GE would welcome and consider any timely USEPAcomments concerning this letter.

II. Anticipated Construction Activities

The 1999 Building 71 OPCA construction activities included provisions to collect and convey (for subsequenttransport prior to treatment/disposal) any leachate that may be generated from the materials placed in theBuilding 71 OPCA. The existing components of the leachate collection system include the base liner, theleachate collection/conveyance piping, and the leachate collection manhole.

As currently constructed, the existing leachate collection system is fully functional and could support, withmanual attendance, "active" use of the Building 71 OPCA. However, over the last several weeks, GE hasidentified and designed modifications to the existing system that allow its future operation to be moreautomated and closer to the anticipated configuration of the final leachate collection system (once the activeconsolidation activities are concluded and closure activities have been completed). As described below, themajority of these modifications pertain to the existing leachate collection manhole.

Attachment 1 to this letter contains the technical drawings and specifications that Blasland, Bouck & Lee, Inc.(BBL) has prepared. The anticipated modifications to the leachate collection system are fully described withinthese drawings/specifications, and are summarized as follows:

• The existing leachate collection manhole will be extended in height by approximately 5 Vz feet. Thenew section will be consistent with the current manhole section (i.e., double-wall, high-densitypolyethylene construction). The existing manhole cover and access hatch will be removed and reused,and following the manhole extension, an access platform will be constructed and the surrounding areawill be graded.

• Within the collection manhole, two leachate pumps (each with a design pumping rate of approximately40 gallons per minute [gpm] when operated individually, and approximately 65 gpm when operatedconcurrently) will be installed. Also included within the collection manhole will be various equipmentto support the pump operations, including piping and valves, level floats, explosion-proofinstrumentation, and related appurtences.

• External to the leachate collection manhole, several activities will be performed, including a partialrelocation of the existing, double-wall leachate conveyance forcemain, provision of electrical powerfrom an existing source, and installation of instrumentation/control wiring between control panelslocated at the leachate collection manhole and the temporary leachate collection/transfer area (discussedbelow).

In summary, the activities described above are intended to allow future leachate collection and conveyanceoperations to be conducted without full-time attendance by GE personnel. As leachate is generated within theBuilding 71 OPCA, it will be conveyed (via gravity flow) to the leachate collection manhole. There, the levelcontrols within the manhole will initiate pump operations. The control logic within the manhole provides foralternate operation of the two pumps (under dry- or low-flow conditions) and both pumps concurrently, ifneeded, under high flow conditions. The control logic also includes provisions to detect and notify GE (viaan autodialer) of potential alarm conditions (e.g., high water level, pump failure, etc.).

The collection of leachate for subsequent disposition will be conducted in a manner similar to that describedin the Work Plan. In general, leachate pumped from the collection manhole will be routed to a designatedcollection area where a temporary storage tank (e.g., a frac tank) and a remote control panel will be located.Once the final method of leachate treatment is determined, and sufficient data are collected regarding actuallong-term leachate generation rates and characteristics, a final permanent storage facility can be designed, ifwarranted.

III. Anticipated Schedule

This letter provides a summary of the modifications identified by GE related to the leachate collection systemfor the Building 71 OPCA. Separate from this letter, GE has prepared detailed design drawings and technicalspecifications for these modifications, and is currently using these materials to solicit cost proposals fromqualified contractors.

GE anticipates that contractor selection will occur within the next few days and that construction activities willcommence shortly thereafter. Tentatively, construction ~ and subsequent start-up testing — of the modifiedleachate collection system will be completed in early May 2000, to allow "active" operation of the OPCA tocommence in mid-May 2000.

Please contact me with any questions concerning this letter and scope of the leachate collection systemmodification.

Sincerely,

Andrew T. Silfer, P.E.Senior Technical Manager
