(Apex), is pleased to provide Moore Petroleum, Inc. (Moore Petroleum} with this Confirmation Soil Boring Workplan for the above-referenced property. A site location map is presented as Figure 1. I BACKGROUND Apex began work at this site on June 14, 1995, after the groundwater monitoring conducted on May 9, 1995, by Emcon. Prior to Emcon, work conducted at the site included subsurface investigations and groundwater monitoring by Delta Environmental Consultants, Inc., of Rancho . Cordova, Nations Groundwater Associates of Sacramento, and Aegis Environmental, Inc. (Aegis), of Roseville, California. Site details maybe found in a "Quarterly Groundwater Monitoring Report," dated April 14, 1995, submitted to Moore Petroleum by Emcon. In early 1995, Emcon installed a soil vapor extraction system and a groundwater treatment system at the site. The soil vapor extraction system consisted of a Remediation Service, Int'I Spray Aeration Vapor Extraction (S.A.V.E.) and was installed per San Joaquin Valley Unified Air I,4 Pollution Control District (SJVUAPCD) permit conditions. The vapor extraction system consists of an internal combustion engine with catalytic converters mounted on the{exhaust pipe. On November 27, 1996, Moore Petroleum received a letter from San Joaquin County Environmental Health Division giving their approval to shut down the vapor extraction system due to low hydrocarbon extraction rates. To date, the vapor extraction system has extracted approximately 2,390 lbs. of TPH, as gasoline, and 7.8 lbs. of benzene.
