Re: GE-Pittsfield/Housatonic River Site Monthly Status Report Pursuant to Consent Decree for September 2011 (GECD900)

Dear Mr. Tagliaferro and Mr. Gorski:

Enclosed are copies of General Electric's (GE's) monthly progress report for September 2011 activities conducted by GE at the GE-Pittsfield/Housatonic River Site. This monthly report is submitted pursuant to Paragraph 67 of the Consent Decree (CD) for this Site, which was entered by the U.S. District Court on October 27,2000.

The enclosed monthly report includes not only the activities conducted by GE under the CD, but also other activities conducted by GE at the GE-Pittsfield/Housatonic River Site (as defined in the CD). The report is formatted to apply to the various areas of the Site as defined in the CD, and to provide for each area, the information specified in Paragraph 67 of the CD. The activities conducted specifically pursuant to or in connection with the CD are marked with an asterisk. GE is submitting a separate monthly report to the Massachusetts Department of Environmental Protection (MDEP), with a copy to the United States Environmental Protection Agency (EPA), describing the activities conducted by GE at properties outside the CD Site pursuant to GE's November 2000 Administrative Consent Order from MDEP.

The enclosed monthly repolt 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, and summarize other groundwater monitoring and oil recovery information obtained during that month. Also, enclosed for each of you (and for Weston) is a CD-ROM that contains these same tables of the analytical data and monitoring information in electronic form.

Please call me if you have any questions.

Sincerely,

Richard W. Gates Remediation Project Manager

ITEM 2

PLANT AREA

EAST STREET AREA 2-SOUTH

(GECD150)

- Performed ambient air monitoring for PCBs and particulate matter in conjunction with remediation actions, as indicated in Table 2-1.* Ambient air PCB sample results are not available for three of the four on-site samples collected during the September 13-14, 2011 sampling event due to a laboratory accident resulting in the loss of those samples (see Table 27). Based on discussions with EPA, GE does not intend to resample since no soil excavation was performed during the time period of collection of these samples.

Notes: All concentrations measured with an EBAM unless otherwise noted. * Measured with a DR-4000. The background monitoring station was located east of Building 9B, between Building 9B and New York Avenue (BK-3) through July 18, 2011. The background monitor

was relocated 120 feet north following sampling on July 18, 2011, due to site activities in close proximity to BK-3, and was renamed BK-3R.

Predominant wind direction determined using hourly wind direction data from the Pittsfield Municipal Airport Weather Station. 1 Monitoring was performed only on days when site activities occurred. 2 The particulate monitors obtain real-time data. The sampling data were obtained by Berkshire Environmental Consultants, Inc. on the sampling date. 3 Sampling period shortened due to power failure. 4 Work week schedule included Saturday from 7:00 AM - 4:00 PM.

SEPTEMBER 2011

e. General Progress/Unresolved Issues/Potential Schedule Impacts (cont’d)

- As noted in prior CD Monthly Reports, several equipment items were removed from Building 9 as part of routine pre-demolition activities in the Building 9 and 10 Complexes, the liquid contents of those items were sampled, and the results of such sampling were verbally reported to EPA on July 19, 2011. As also previously noted, a second sample from one item was collected on August 3, 2011. The final results of the August 3, 2011 sample were received and confirmed on September 20, 2011 and required notification to EPA. GE made the required verbal notification on September 23, 2011. Based on communications between GE and EPA, the formal written follow-up notification for both of these verbally reported sample results will be held in abeyance until the comprehensive pre-demolition work in the Building 9 and 10 Complexes has been completed. If, following completion of that work, additional equipment items requiring notification pursuant to GE’s Consent Agreement and Order (CAO) under the Toxic Substances Control Act (TSCA) are identified, such additional items will be identified, along with the original items (verbally reported on July 19, 2011 and September 23, 2011), in the formal written follow-up report.

The background monitoring station was located east of Building 9B, between Building 9B and New York Avenue (BK-3) through July 18, 2011. The background monitor was relocated 120 feet north following sampling on July 18, 2011, due to site activities in close proximity to BK-3, and was renamed BK-3R.

Predominant wind direction determined using hourly wind direction data from the Pittsfield Municipal Airport Weather Station. 1 Monitoring was performed only on days when site activities occurred. 2 The particulate monitors obtain real-time data. The sampling data were obtained by Berkshire Environmental Consultants, Inc. on the sampling date. 3 Represents workday schedule from 3:30 PM - 5:00 PM. 4 Represents workday schedule from 8:00 AM - 4:00 PM. 5 Sampling period shortened due to a power failure.

Two of these locations are situated in the 1½ Mile Reach: Lyman Street Bridge (Location 4) and Pomeroy Avenue Bridge (Location 6A). A composite grab sample was collected at each location and submitted to Northeast Analytical for analysis of PCBs (total), TSS, POC, and chlorophyll-a, as identified in Table 14-1. The sample collected at Pomeroy Avenue Bridge was also analyzed for volatile suspended solids (VSS). (The other eight locations are discussed under Items 15 and 20 below.)
