r <br /> Mr. Randy Fischback - 2 - 21 April 2003 <br /> 3. The EA does not include a discussion of facility operations, such as how the <br /> manufactured product is transferred to the warehouse or shipping yard and the potential <br /> for releases from transferring the product. Dow should provide this information. <br /> 4. The EA states motor and hydraulic oil were stored on site, but does not include <br /> information showing that petroleum was analyzed for the soil or groundwater samples. <br /> Dow must include analytical results showing that petroleum constituents have not been <br /> 1eleased at the site. <br /> 5. On 6 May 2002, Regional Board staff sent a letter stating that diethylene glycol could <br /> possibly be a concern,but the EA does not include analytical results for it. The May 2002 <br /> letter also suggested vapor phase samples for volatile organic compounds (VOCs). Dow <br /> needs to collect additional samples to analyze for glycols and soil vapor samples for <br /> VOCs to determine whether there have been releases at the site. <br /> 6. The EA includes the June 2001 Phase II Environmental Site Assessment(Phase II Report) <br /> submitted by O'Brien& Gere Engineers, Inc. but not the November 2000 Phase I <br /> Environmental Site Assessment(Phase I Report) submitted by Environmental Resources <br /> Management Company. The Phase I Report would have been helpful to determine what <br /> materials have been manufactured at the facility because Section 1 of the EA states that <br /> the facility manufactured rigid insulation board, Section 3.2.1 states an aqueous waste <br /> stream and a combustible cleaning solvent were generated at the facility, and the Phase H <br /> Report states it is a foam manufacturing facility. It is also unclear what the facility <br /> manufactures and how the waste streams generated relate to the production of insulation <br /> board or foam. Furthermore, there is no discussion of where these hazardous materials <br /> were generated or stored on site to determine whether sampling locations performed to <br /> date are appropriate. <br /> 7. The EA includes logs of drilling activities but does not include organic vapor meter <br /> readings. Boring logs need to include these readings to help assess whether pollution is <br /> in the vapor phase and for workers safety. <br /> 8. The EA discusses the development of the four monitoring wells but does not include well <br /> development logs. The water sampling logs state the water is moderately turbid to murky <br /> brown, which shows that the wells may not have been properly developed. Regional <br /> Board staff understands that the monitoring wells were not producing sufficient water to <br /> fully develop the monitoring wells, and therefore, Dow needs to attempt to develop the <br /> wells again when there is a sufficient amount of water in the wells. <br /> 9. Appendix D of the EA states that a data diskette is included. Regional Board staff did not <br /> receive the data diskette and requests Dow provide the data diskette if it contains <br /> additional information not already included in the EA. <br /> 10. Based on the conepenetrometer testing (CPT) logs in Appendix D, it does not appear that <br /> the bottom of the gravelly-sand zone was found in CPT-01 or CPT-03. Dow needs to <br />
