Mr. Maurice Benson <br /> November 12, 2008 <br /> Page 3 <br /> Banta Road, as no data are currently available to prove these mechanisms exist <br /> in this area. <br /> Recommendations: <br /> 1. DESJC should provide the regulatory agencies ample time to review, comment, <br /> and receive responses to regulatory comments prior to the commencement of <br /> proposed/planned fieldwork. Commencement of fieldwork prior to regulatory <br /> review and submittal of comment breaks the rules and conditions specified in <br /> section 7.7 and 18.4 of the DDJC-Tracy Federal Facilities Agreement, including <br /> Comprehensive Environmental Response, Compensation, and Liability Act <br /> process. <br /> 2. DTSC recommends that DESJC delineate the TCE plume east of Banta Road <br /> both vertically and horizontally in future fieldwork efforts. The documentation is <br /> necessary to accurately depict the true areal extent of the TCE plume for Record <br /> of Decision documentation, and it will provide data necessary to determine <br /> whether the natural attenuation processes are occurring as presented in reports. <br /> DTSC recommends that DESJC submit a work plan to the regulatory agencies in <br /> the near future to clearly identify the areal extent of the TCE plume east of Banta <br /> Road for Record of Decision documentation, and to prove whether the natural <br /> attenuation mechanisms truly exist in this area. <br /> If you have any questions or comments regarding this letter, please feel free to contact <br /> me at (916) 255-3713 or e-mail me at pmacnichCar)dtsc.ca.aov. <br /> Sincerely, <br /> Peter MacNicholl, P.E. <br /> Hazardous Substances Engineer <br /> Sacramento Office <br /> Brownfields and Environmental Restoration Program <br /> cc: See next page. <br />
