Dembroff TEL. NO: 209-583-3374 <br /> BACKGROUND: <br /> Ultramar purchased site from Conoco in July 1990. Several <br /> ground-water monitoring wells had been installed by Conoco <br /> (formerly Kayo Oil Company) at and near the site. At the time <br /> of site purchase, all but one well (MW-20) was dry. A vapor <br /> extraction system was operated at the site until the end of <br /> December 1990. The thermos unit was then removed and <br /> permitting for a catalytic unit was initiated. <br /> In February 1991, three additional ground-water monitoring <br /> wells (MW-34, MW-35, and MW-36) were installed along the <br /> south, east, amd west boundarlies of the site in an effort to <br /> evaluate both ground-water gradient and water quality. Soil <br /> and ground-water analyses showed nondetectable to low TPHg and <br /> benzene concentrations. <br /> i <br /> SUMMARY OF THISQUARTER'S ACTIVITIES: <br /> EVAX Technologies tested the vapor extraction piping installed <br /> previously by DuPont Environmental . A proposal for piping <br /> repair and modification is in preparation. A permit <br /> application for a catalytic incinerator was submitted to the <br /> APCD for processing. This application has been with the APCD <br /> for over 60 days. <br /> As mentioned above, three borings/wells were installed and <br /> sampled in February 1991. Additional ground-water samples <br /> were collected in April 1991 to verify laboratory results and <br /> initiate quarterly a ground-water monitoring program. <br /> BEACi::-N <br /> A Member of the Ultramar Group of Companies #1 Quality and Service <br /> ullramar' <br />
