Products Company <br /> 2410 Camino Ramon <br /> San Ramon, CA 94583-0804 <br /> RE: ADDENDUM TO WORK PLAN FOR ADDITIONAL <br /> SOIL ASSESSMENT DATED APRIL 12, 1994 <br /> CHEVRON SERVICE STATION 9-0557 <br /> 739 SOUTH CENTER STREET <br /> STOCKTON, CALIFORNIA <br /> Dear Mr. Hunter: <br /> Groundwater Technology, Inc. submits this letter as an addendum to the work plan dated April 12, <br /> 1994 for Chevron service station #9-0557 located at 139 South Center Street in Stockton, California. <br /> This addendum summarizes the changes to the scope of work outlined in the work plan mentioned <br /> above. After discussions with San Joaquin County Public Health Services - Environmental Health <br /> Division (SJCPHS-EHD) personnel, Chevron requested that Groundwater Technology submit the <br /> following changes to the April 12, 1994 work plan: <br /> The soil boring originally proposed near the southwestern corner of the tank pit has <br /> been moved to the middle of the northern end of the former tank pit as shown on <br /> Figure 1. The new position of this soil boring is closer to the location of soil sample <br /> TP-3 (elevated TPH-G concentrations) collected during tank removal activities in <br /> 1989. The soil boring will be drilled, sampled and analyzed according to the <br /> methods outlined in the April 12, 1994 work plan to a depth of 45 feet below ground <br /> surface (BGS). <br /> • The soil boring proposed for the planter adjacent to the pump islands has been <br /> replaced by two soil borings placed at the southern end of each pump island as <br /> shown on Figure 1. Soil borings near the end of the pump islands are closer to the <br /> locations of soil samples P-2 and P-4 (elevated TPH-G concentrations) collected <br /> during tank removal activities in 1989. The soil borings will be drilled and sampled <br /> and analyzed according to the methods outlined in the April 12, 1994 work plan to a <br /> Offices throughout the U.S.,Canada and Overseas <br />
