Earnest TEL. NO: 209-583-5571 <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 thermox 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, and west boundaries 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 /> A permit application for a catalytic incinerator was submitted <br /> to the APCD for processing and the unit began operation on <br /> August 23, 1991. <br /> The catalytic unit was removed and granular activated carbon <br /> was installed on September 9, 1992. <br /> SUMMARY OF THIS QUARTER'S ACTIVITIES: <br /> Groundwater Monitoring was performed February 5, 1993. <br /> A Member of the Ultramar Group of Companies #t Quality and Service <br /> UftrBmar <br />
