Re: GE-Pittsfield/Housatonic River Site Monthly Report for January 2000

Dear Mr. Olson and Ms. Cutler:

Enclosed are copies (five for EPA and four for MDEP) of General Electric's monthly progress report for January 2000 for activities conducted by GE at the GE-Pittsfield/Housatonic River Site (as defined in the Consent Decree lodged on October 7, 1999). Now that the Consent Decree has been lodged, we have revised the format of the monthly report to apply to the various areas of the Site defined in the Consent Decree and to conform to the requirements of Paragraph 67 of the Consent Decree.

The enclosed monthly report follows this revised format. However, since GE is still continuing, prior to entry of the Consent Decree by the Court, to conduct some activities at the Site under prior authorities (i.e., the RCRA Corrective Action Permit from EPA and the 1990 Administrative Consent Orders with the MDEP), we have included such activities in this monthly report where such activities were conducted at the Consent Decree Site. To distinguish those activities from the activities conducted pursuant to the Consent Decree, the latter are marked with an asterisk. GE will be submitting a separate monthly report to MDEP, with a copy to EPA, describing the activities conducted at properties outside the Consent Decree Site (e.g., activities conducted under the off-site fill property program).

The enclosed monthly report includes, where applicable, tables that list the samples collected during the subject month, summarize the analytical results received during that month from sampling or other testing activities (excluding data from miscellaneous soil sampling activities conducted pursuant to GE's Excavation Protocols), and summarize j other groundwater monitoring and oil recovery information obtained during that month, j Also enclosed for each of you, pursuant to Paragraph 67 of the Consent Decree, is a ( diskette that contains in electronic form the same analytical data and monitoring

i

information contained in those tables, as described above. Sampling results from miscellaneous soil sampling conducted pursuant to GE's Excavation Protocols are included in final excavation completion reports submitted to the Agencies during the subject month and also are attached to this monthly report and referenced under the appropriate areas.

Please call John Ciampa or me if you have any questions.

Yours truly,

GE Project Coordinator

Background

The General Electric Company (GE), the United States Environmental Protection Agency (EPA), the Massachusetts Department of Environmental Protection (MDEP), and other governmental entities have entered into a Consent Decree which was lodged in federal District Court on October 7, 1999. The Consent Decree is currently subject to public comment and review by the Court prior to final entry. In accordance with Paragraph 67 of the Consent Decree, GE has prepared the following monthly report that summarizes the status of activities conducted at the GE-Pittsfield/Housatomc River Site ("Site") (as defined in the Consent Decree).

The enclosed report covers activities in the areas listed below (as defined m the Consent Decree and/or the accompanying Statement of Work for Removal Actions Outside the River (SOW)). Only those areas that have had work activities for the month subject to reporting are included. However, prior to entry of the Consent Decree by the Court, where work activities were conducted in a particular area at the Site pursuant to the 1994 RCRA corrective action permit from EPA and/or the 1990 Administrative Consent Orders executed by GE and MDEP, such activities are included in this report. For a particular area, those activities conducted pursuant to or in connection with the Consent Decree are noted with an asterisk.

ITEM 13

HOUSATONIC RIVER AREA UPPER 1/2 MILE REACH

JANUARY 2000

*A11 activities described below for this item were conducted pursuant to the Consent Decree.


- Completed sheetpiling installation m Cells C and D.

- Dewatered Cells C and D.

- Observed and reported an oil sheen on January 6, 2000 during sheetpile installation.

- Continued excavation in Cell C. GE, with concurrence from EPA, decided to remove an additional two feet of black oily river sediment in front of the permanent sheetpiling (approximately 160 CY of TSCA material).

- Completed bank removal activities adjacent to the unstable excavation areas in the upstream section of Cell C Stabilized the upstream end of Cell C where "boiling" occurred.

- Completed sediment removal (except for the downstream end) and began restoration activities m Cell C.

- Continued verification of excavated and restored elevations in Cell C

- Restored an approximate 120 foot section of Cell C, upstream end, including fabric, sand fabnc/geognd, and rock.

- Backfilled area in front of source control sheetpiles where an additional two feet of material was removed.

- Began grouting operations at source control sheets. Remobihzed at upstream end to avoid DNAPL area.

- Encountered pocket of DNAPL at the downstream end of Cell C near the Cell D interface, which resulted in the following action:

- Notification of MDEP, EPA, EPA Region 1 spill response and the NRC of the new oil sheen and visible DNAPL on January 24, 2000.

- Immediate isolation of oil source from other excavated areas.

- Recovered approximately 66 gallons of oil as of January 31, 2000.

- Excavated area where oil source was observed, with further isolation from Cell C.

- Revised containment and product recovery plan based on excavation results

- Maintained stockpiled material in Building 65 and Building 33X (TSCA and non-TSCA).

ITEM 13 (cont'd)


JANUARY 2000

- Conducted air particulate and PCB monitoring.

- Conducted water column (PCB and TSS) monitoring.


- Water column results for TSS from January 3 to January 31, 2000 (see attached table).

- Water column results for PCB on January 7 and January 20, 2000 (see attached table).

- Particulate air monitoring results from January 3 to January 31,200 (see attached table).

- PCB air monitoring results from January 12-13,2000 (see attached table).

- Backfill soil sampling results (see attached table).

- DNAPL sampling results (see attached table).

- Effluent priority pollutant sampling (see attached table).


- Estimated planning timetable for the entire project revised January 7.

- Monthly report for work completed in December 1999.

- Meeting Summaries for project status meetings held weekly.

- Miscellaneous construction material specification submittals.

d. Upcoming Scheduled Activities (next six weekst

- Develop and submit a DNAPL investigation work plan for EPA review and approval and implementation by GE.

- Evaluate results of DNAPL investigation for the effects on other operations.

- Evaluate engineering options for addressing DNAPL in Cell C.

- Continue communication between GE, EPA and DEP on a regular basis to provide updates on the DNAPL situation and discuss various alternatives for collection and containment.

- Continue air and water column monitoring.

ITEM 13 (cont'd)


JANUARY 2000


GE is currently discussing scheduling issues with EPA, including final completion date. Encountering DNAPL has delayed completion of Cell C as well as excavation of Cell D. The grouting subcontractor has been placed on hold pending results of the DNAPL investigation plan. GE has notified EPA and MDEP that the finding of DNAPL in Cell C, together with the necessary response measures, may potentially delay completion of the Upper 1/2-Mile Reach Removal Action and, if so. would constitute a "force majeure" event under the Consent Decree.
