Re: GE-Pittsfield/Housatonic River Site Newel1 Street Area I (GECD440) Restoration of Parcel 59-23-22

Dear Mr. Tagliaferro:

As you are aware, the General Electric Company (GE) is currently involved in the performance of EPA- approved removal actions at the Newel1 Street Area I Removal Action Area located in Pittsfield, Massachusetts. As part of the access negotiations prior to the initiation of removal actions at Parcel J9- 23-22, GE agreed to certain owner-requested modifications concerning the final restoration surfaces for this property. This letter presents a brief summary of the proposed modifications to the EPA-approved Technical Drawings and an evaluation of the potential impact such changes may have on site drainage.

Prior to the initiation of the removal actions at Parcel J9-23-22, several existing surface cover types were present at that property, including the following:

A gravel drivewaylparking lot which extended from Newel1 Street to approximately 50 feet northwest of the rear building.

Miscellaneous bituminous asphalt and concrete pads.

Compacted earth, including a drainage swale located along the property line between Parcel J9- 23-22 and 59-23-23 which extended from just south of the rear building to a riprap outlet channel at the rear of the property.

Following performance of the required soil removal activities and placement of backfill (as required), the final surface cover for the property will be restored as follows:

The portion of the property located between the northern building and Newel1 Street will be restored with a compacted 12-inch processed gravel base followed by a two-inch layer of asphalt pavement.

The portion of the previously unlined drainage swale extending from just south of the rear building to the riprap drainage swale at the rear of the property will be restored with six inches of compacted gravel and a two-inch layer of asphalt.

The restored surface cover for the remainder of the property -- which includes the engineered barrier area -- will consist of a minimum six-inch compacted gravel layer. However, the area over the barrier will be restored with an 18-inch compacted gravel layer including a layer of geotextile located approximately six inches below grade, to serve as an indication when six inches of gravel have been displaced and maintenance activities are necessary.

To reflect these changes, Technical Drawings 6, 12, 13, and 14 of the August 2003 Final RD/RA Work Plan have been revised and included herein. In addition to these revisions, Technical Drawing 12A was developed to present certain restoration details associated with the drainage swale, among others.

Based on the owner-requested modifications to the surface cover types at Parcel 59-23-22 and as requested by EPA, GE has performed additional evaluations to determine the impact (if any) during future precipitation events, with an emphasis on the existing riprap outlet channel at the rear of the property and the recently restored riverbank. GE has analyzed the pre-construction and post-removal action hydraulic runoff conditions for this property to determine whether changes to the existing riprap outlet channel are appropriate.

Prior to the recently initiated soil removal activities, stormwater runoff from Parcel J9-23-22, along with runoff from adjacent contributing watershed areas, flowed to an unlined drainage swale located along the property boundary between Parcel J9-23-22 and 59-23-23. Flow conveyed by this swale continued into a riprap swale located at the northeast comer of the property. The riprap swale then conveyed the runoff to the aforementioned riprap outlet channel constructed within the southem riverbank of the East Branch of the Housatonic River.

As previously indicated, the final restoration surfaces at Parcel J9-23-22 will consist of compacted gravel and, in some areas (including a portion of the restored drainage swale), asphalt pavement. To determine the drainage impacts (if any) to the riprap outlet channel as a result of the proposed surface cover modifications, the 2-, lo-, and 25-year, 24-hour storm events were analyzed under existing (i.e., pre- construction) and post-restoration conditions for the watershed dischargng to the riprap outlet channel. The following table summarizes this analysis:

As indicated above, the change in surface cover conditions associated with site restoration will result in a minor increase in peak discharge runoff to the riprap outlet channel. Based on site conditions observed on June 17, 2004, the riprap channel constructed within the riverbank (i.e., the portion located below the crest of the riverbank) appears to be well established with no apparent signs of instability. Considering the current condition of the outlet channel and the anticipated minimal increase in peak discharge, the bank portion of the outlet channel should remain stable following completion of the site restoration activities. However, GE proposes to restore the riprap swale upgradient of the outlet channel (i.e., the portion located above the crest of the riverbank) in accordance with Detail D on Technical Drawing 12A to better contain and convey runoff to the riprap outlet channel. Finally, to further improve flow control within the riprap swale and outlet channel, GE proposes to install a check dam at a location approximately 5 feet upgradient of the riverbank crest. The cross-section of this check dam is also included in Detail D on Technical Drawing 12A
