The only resources CSEC references for site history information prior to the 1940's (site occupied by Nonotuck Silk Manufacturing Co.) were Historic Altas Map descriptions and information from the current property owner. Please describe the extent to which other potential information resources were researched, including, but not limited to: Sanbom Company maps, Local Historical Commissions, and Libraries; 2. Please provide information concerning types, names, uses, and storage locations of all oil and/or hazardous material historically used at the site, as well as related manufacturing processes. This must include information relative to silk manufacturing, metal plating, and machine shop operations; 3. Please provide information concerning historical waste management and disposal practices at the site (during silk manufacturing, metal plating, and machine shop operations), including any subsurface disposal via floor drains or dry wells, as well as identification of any disposal areas or points of discharge; 4. Please provide further documentation describing the subsurface utilities serving or transecting the disposal site, including any storm drain sewer lines; CSEC's site plan shows the sanitary sewer line which the floor trench reportedly discharges into as running into the "abandoned mill" building located to the southwest of the site. Please provide additional information concerning this sewer line, including its installation date and ultimate discharge point; NOA 1-11303 5 6. Please identify any environmental permits issued to the facility when metal plating and machine shop operations occurred there, including, but not limited to, any local permit(s) to discharge wastewater to the sanitary sewer system; 7. Nickel was identified as one of the materials used in the plating operation Please provide the justification for not including nickel as an analyte in the samples collected at the site; 8. CSEC's reports described the concrete floor trench as a drainage trench, an "overspillage facility", and a floor drain. Please identify when this trench was installed, and if it has always been connected to the sanitary sewer line (if this is not the case, please identify the previous location(s) to which the trench discharged). In addition, please describe the function of this trench (during the various manufacturing processes which occurred at the site), and how oil and/or hazardous material historically used at the site (in silk manufacturing, metal plating, and machine shop operations) would have made their way to this trench; 9. Please describe any testing that was done to demonstrate that the concrete floor trench, sump, and discharge pipe to the sanitary sewer line, or associated connections and joints, did not leak and thus serve as the source of a release(s) of oil and/or hazardous material to the soils and subsurface at the site; 10. Please identify and characterize any suspected source(s) for the oil and hazardous materials (e.g., PCE, TCE, Cadmium, and TPH) found in the soil and/or groundwater at the site. This may include, but not be limited to, floor drain(s), dry well(s), and storage or waste container(s); 11. Please document the approximate horizontal and vertical extent of contamination at the site; 12. Please indicate whether the floor drain's sump collection point/sediment trap also required sampling and cleaning out, and whether this was done; 13. Please provide documentation of the disposal of the two pails of metals-containing sediment that were removed from the concrete floor drain at the site, including documentation of any additional analytical characterization (e.g.,pH, TPH) which was required prior to disposal; 14. Please document any calibration, adjustment, or checking of the Photoionization Detector unit(s) prior to its use to screen soil and sediment samples at the site, and confirm that the appropriate instrument lamp was used; 15. Please document the preservation procedures utilized for the groundwater samples which were analyzed for Halogenated and Aromatic VOCs; 16. Please document any preservation procedures utilized for the groundwater sample (MW-3) the laboratory filtered and analyzed for Cadmium in lune, 1996; 17. Please provide justification for dropping the Cadmium concentration found in MW-3 when sampled in Nov., 1995 (1.4 mg/I) from further consideration (versus e.g.,averaging in this value); and, 18. It appears that the RAO applies to the entire parcel of property at 660 Riverside Drive. Please confirm or revise this, and supply a site plan with the boundaries subject to the RAO highlighted.

Woodard & Curran Inc. is conducting environmental response actions for Bay State Gas at the location of the former Northampton Gas Works Site(the current location of the Roundhouse Parking Lot). The site is a listed Tier II site with the Massachusetts Department of Environmental Protection(MADEP). We plan to complete the test pits in March when it is likely the ambient air temperature is low in order to reduce the release of odors via volatilization from soil. Based on our previous assessment activities at the site, we are preparing to prevent the release of nuisance odors from the excavated soil. Where the soil has been impacted by material from the former gas works, the soil may have a strong naphthalene(or moth- ball like) odor. It is common practice to complete excavations at former gas works sites during the cold weather months to minimize nuisance odors. We have met with Bill Letendre, the Northampton Parking Lot Manager, who has agreed to support our excavation plans within the Roundhouse Parking Lot. We propose to excavate approximately six test pits in the northern portion of the parking lot (see attached drawing) to assess the presence or absence of foundations and other buried structures formerly used by the Gas Works. The test pits are planned to be about 3 feet wide by 6 to 8 feet deep. The length of the test pits will range from about 10 feet to approximately 60 feet. The pits will likely lake about an hour to dig. Soil removed from the excavation will he temporarily stockpiled adjacent to the pit, and used to backlit' the excavation upon completion. We will temporarily install gravel at the ground surface after completing the excavation, and retum to the parking lot to install asphalt patches in April. We will coordinate test pit activities with numerous City departments (DPW, Planning, Parking Lot Authority, and Board of Health). The test pit activities will result in closure of a portion of the parking lot for a few days to safely and efficiently complete the excavations. If you have any questions or comments, please contact me at 800/446-5518. Sincerely. WOODARD& CURRAN INC. Lu ofd Robert W. McGrath Project Manager 980 Washington Street • Dedham,Massachusetts 02026.
