PACIFIC COAST f <br /> PRODUCERS CANNING PLANT, 32 TOKAY, LODI, CALIFORNIA' <br /> Dear Ms. Turkatte: <br /> I want to take this opportunity to thank you for our meeting in your offices on July 1, 1992 <br /> and to inform you of Pacific Coast Producer's proposed next steps based on our discussions <br /> r in that meeting. F " <br /> During our meeting we discussed the;data obtained from the.April 1991 sampling episode <br /> and how it was incorrectly reported in our July 1991 report. It appears that the soil <br /> contamination of potential concern to San'Joaquin County is centered around the five (5), <br /> foot depth as opposed to the originally reported 20 foot depth, and the locations of this _ <br /> contamination of concern are near the center and the eastern perimeter on the original tank , <br /> location, not the southern.,and_westerE p9rime�ters,a :�nreviously,xepnrted. vYon have <br /> corrected version of Table 1 in your-possession. R r <br /> We discussed the cleanup levels which would be imposed on this project in order for Pacific. <br /> Coast Producers (PCP) to obtain "clean closure" for the tank removal and remediation of <br /> contaminated soils. Based.on the data obtained so far regarding the soil contamination a <br /> certification of clean closure would not be'possible without reducing the contaminants to the <br /> County's cleanup level objectives. You conveyed the following cleanup1evels for the soil <br /> at the site to be`protective of groundwaterat the subject site: Non-detectable for BTX&E <br /> (currently 5 ppb), 10 ppm for gasoline; and 100 ppm for diesel. I assume that oil and grease k ' <br /> would have'the same cleanup level as diesel. <br /> Although a majority of discussion during our meeting ;centered on our proposed plan to Y <br /> conduct further investigation to characterize the site,you,did mention that our.'Original April <br /> sampling and analysis could serve as a screening mechanism for the further work at the site. <br /> 819 F Street • Sacramerifo,CA'• 95814 (916)553-3111 • FAX;(916)553-'b250 <br /> ��C'� <br />
