O. Box 4050 <br /> Richmond, CA 94804-0054 <br /> CHEVRON PIPE LINE COMPANY, ALDEN PARK SITE, TRACY, SAN JOAQUIN <br /> COUNTY <br /> We have reviewed our files and available reports on the Alden Park Site in the City of Tracy. <br /> Enclosed is a memo describing the status of soil and ground water investigations and cleanup <br /> activities at the site. <br /> Our files show that it has been several years since Chevron conducted pilot tests to develop methods <br /> for soil and ground water cleanup of the petroleum residues. Further action on this site is needed. <br /> In a 22 September 1993 conversation you had with Wendy Cohen, you scheduled a meeting for <br /> 27 October 1993 to review the site and discuss further actions. <br /> In our 9 September 1993 phone conversation, you told me the annual ground water sampling would <br /> take place this month and you agreed to inform me ahead of time of the exact date and time. This <br /> sampling should include all the wells and samples should be tested by EPA Methods 601 and 602 <br /> and for total petroleum hydrocarbons and polynuclear aromatic hydrocarbons. <br /> If you have any questions, please call me at (916) 255-3054. <br /> WN �v L, Uum,, <br /> - by DAVID E.
