collected UST samples T2-N-16.0 and T3-N-15.0.The other stockpile represents approximately twenty <br /> seven cubic yards of soil that was generated on October 3, 1995 during the removal of hydrocarbon- <br /> impacted soil that was beneath Touchstone's previously collected dispenser sample,D-5-3.0.Total depth <br /> of the resulting excavation was seven feet below grade. Soil samples were collected by Touchstone at the <br /> limits of this excavation on October 3, 1995 without direct oversight by SJCPHS personnel. Chevron will <br /> provide at least forty eight hour notification to SJCPHS of its intent to sample these two stockpiles for <br /> landfill disposal characterization. <br /> On October 3, 1995,Touchstone also collected a soil sample from beneath a sand and grease trap that was <br /> removed from the service bay floor. During this sampling there were approximately two cubic yards of soil <br /> stockpiled onsite. As specified in the Notice To Abate,which was issued at the subject site by Ron Roe of <br /> your staff on October 4, 1995, Chevron will submit a workplan to describe further excavation in this area <br /> and resulting stockpile characterization. <br /> By way of this letter,Chevron is providing notification to your agency that it intends to sample the <br /> remaining two stockpiles(approx. 67-cubic yds:)on-Wednesday,-:October 11;.:1995.-A representative from- <br /> Touchstone Developments will be at the site at 9:00 am. It was my understanding from our telephone <br /> conversation today that this sampling event would be considered valid even without the direct oversight by <br /> SJCPHS personnel. <br /> The analytical results of all stockpile sampling will be forwarded to BFI Landfill in Livermore,California. <br /> Once approval is received from that facility and concurrence received from your agency, Chevron will <br /> then proceed to load and transport soil stockpiles offsite. I will look forward to receiving your <br /> concurrence. <br /> Thank you for your willingness to consider this proposal for the disposal of stockpiled soils at the subject <br /> site.
