Mr. Marty Hartzell <br /> Re: Former American Forest Facility <br /> 2801 West Lane <br /> Stockton,California <br /> URS Project No.41-15884019.00 <br /> Dear Mr. Hartzell: <br /> Pursuant to our conversation on November 15, 2001, I have prepared copies of the following three documents <br /> for your reference: <br /> • Closure Request Report prepared by URS and dated July 31, 2001; <br /> • Fate and Transport excerpt from Draft Amended Request for Closure prepared by Dames&Moore and dated . <br /> August 1, 1994;and <br /> • Risk Assessment excerpt from Feasibility Study/Remedial Action Plan prepared by Dames &Moore and <br /> .dated July 13, 1988. <br /> A.copy of the Closure Request Report was issued to you on November 28, 2001. Attached please find copies <br /> of the two excerpt documents. <br /> Tables 5 and 6 of the 2001 Closure Request Report summarize analytical results for non-diesel compounds in <br />` groundwater samples collected at the site. As the tables indicate, the only non-diesel contaminant of concern <br /> documented at the site is 1,2-dichloroethane,which has only been detected more than once at two of the seven <br /> wells at the site. This indicates an impact that is limited in areal extent,and in concentration.Based on this data, <br /> I and other criteria including the low-level impacts of diesel and the lack of a receptor,closure for the site has been <br /> requested. <br /> fAn additional groundwater monitoring event will be conducted during December 2001. Analytical parameters <br /> will include diesel using EPA Method 8015M, and organic compounds using Method 8260B. <br /> Finally, in order to maintain communication between all participating parties, you will receive a copy of any <br /> future reports which are issued to the San Joaquin PHS/FHD. <br /> k <br /> If you have questions regarding this project, please contact me at (9I6) 679-2000. <br /> 4 Sincerely, <br /> i URS <br /> ack Ke <br /> i Senior eologist <br /> c: Mr. Sam Savig, San Joaquin PHSIEHD <br /> William Bergvall, attorney for AFPC <br /> uas CorporafSn <br /> Crown Corporate Center <br /> 2870 Gateway Oaks Drive, Suite 300 <br /> Sacramento,CA 95833 <br /> TeL 916.679.2000 K:1WINctters11,120301.doc <br /> Fax: 916.679.2900 <br />
