Because it is a <br /> ground water contaminated site 1 a proposal was to be submitted to <br /> both the local health district and to the Regional Board for review and <br /> approval.. As I explained to Diane, the proposal should be based on the <br /> approved Task 3 of the HLA report of 29 April 1988. Namely that the <br /> borings and wells are based upon the work done in the soil/gas survey <br /> in Task 2. <br /> Un 07 Pa t kton <br /> Keith Romstad of Applied Geosystems brought their v�,orkplan proposal <br /> for the site for our review and concurrence <br /> today- The Lab results <br /> from their initial work has been tel <br /> ecopxed to Dave Carls of SJLHD an 21 <br /> June 1988. My review today'shows that the tank cavity has 1900 ppm <br /> r in the NE corner -of the excavation at 22 feet; and 1800 ppm in the <br /> center. This was the extent of the backhoe excavator. Seven other <br /> periphery samples showed levels at 2.4, 1. 8 and five at < 1. 0 ppm. <br /> The report is being prepared for us. Applied Geosystems and Unocal are <br /> aware that the work cannot proceed until the Preliminary Report its <br /> reviewed and approved as complete. Applied Geosystems will modify <br /> their proposed workplan to conform to our Regional Board reporting <br /> requirements. Unocal has provided a letter of agreement to develop a <br /> remediation <br /> plan for the site. The Preliminary Report and revised <br /> workplan with proposers time schedules are due on 8 -Tuly 1988. <br /> If Unocal places their new tanks in the excavation, they are aware <br /> that the operation of the facility will not interfere with the remediation <br />
