PHS/EHD has the <br /> following comments for your consideration. <br /> The excavation of soil contamination was initiated and samples collected September 16, 1992 without <br /> PHS/EHD notification or inspection. Subsequently, an office hearing was scheduled to discuss confirmation <br /> sampling. Confirmation samples were collected October 22, 1992 under PHS/EHD inspection. <br /> The results of confirmation sampling indicated that significant soil contamination had been removed. The <br /> contaminated soil which was removed is currently stockpiled on site awaiting final disposition. PHS/EHD <br /> cannot concur with the request for closure until the contaminated stockpiled soil has been either treated or <br /> disposed of at an appropriate facility. <br /> J <br /> Residual soil contamination indicated by confirmation sampling is below concentrations which pose a threat <br /> to groundwater. Therefore,PHS/EHD concurs with the request to backfill the excavations with clean imported <br /> soil. <br /> Once soil disposition documentation has been submitted and the excavations properly backfilled under City <br /> of Stockton grading permit, PHSIEHD will consider the site for closure. <br /> If you have any questions or to schedule a site inspection, please contact Mary Meays,!REHS, of my staff at <br /> (209) 468-0337. <br /> Jogi Khanna, M M.P.H. <br /> Health Offi <br /> I, <br /> A <br /> u e A.
