This <br /> letter also presents a brief description of the well to be <br /> destroyed, its location, and the proposed method of <br /> destruction. <br /> Monitoring well BCS is located approximately 75 feet north of <br /> northwest corner of Georgia-Pacific Corporation's former Tracy, <br /> California, packaging plant, within the right-of-way for a West <br /> Side Irrigation District canal (Figures 1 and 2) . The <br /> packaging plant is located at 75 West Valpico Road in Tracy, <br /> California. <br /> The well was constructed in February 1985 as part of a <br /> groundwater investigation conducted by Brown and Caldwell <br /> Consultants on behalf of Georgia-Pacific Corporation. It <br /> consists of 2-inch diameter polyvinyl chloride (PVC) blank and <br /> slotted casing extending from ground surface to a depth of 40. 5 <br /> feet below grade (Figure 3) . The slotted interval (0. 020-inch <br /> slot size) extends from 20. 5 to 40. 5 feet depth. A cement <br /> grout seal, which extends from ground surface to 14 feet depth, <br /> is separated from the sand filter pack material by a 3. 5 foot <br /> thick bentonite seal (14 to 17. 5 feet) . <br /> The well was used as a water level measurement and groundwater <br /> sampling location through 1988, but its use was discontinued in <br /> January 1989 under an agreement between Georgia-Pacific and the <br /> 11 <br /> Aia A7✓"0 <br />
