(AGE) has prepared this work plan for the destruction <br /> of groundwater monitoring wells, soil-vapor extraction wells, air-sparge wells, dual phase <br /> extraction wells, and shallow soil-vapor wells at 375 West Hazelton Avenue, Stockton, <br /> California (site). <br /> 1.0. INTRODUCTION <br /> The site area is occupied by Sierra Lumber Manufacturers, a wood-products processing <br /> and manufacturing facility. In 1988 hydrocarbon impact was detected on site during the <br /> removal of a 1 ,000-gallon UST. Monitoring wells MW-1 through MW-8, vapor extraction <br /> wells VW-1 through VW-6, and air sparging wells AW-1 through AW-5 were installed at <br /> the site in relation to this release designated Case #1. In 2004 a separate release on site <br /> related to a tank of unknown size recorded to have been removed in the late 70's or early <br /> 80's was discovered. This release was designated Case #2. Monitoring wells MW-9 <br /> through MW-21, dual phase extraction wells DPE-1 though DPE-4, and the shallow soil- <br /> vapor well SV-1 were installed on the site in relation to Case #2. MW-11 was destroyed <br /> in April 2006. MW-10 and MW-14 were destroyed in December 2006. Well construction <br /> details are summarized in Table 1. <br /> A total of thirty-four (34) wells are located at the site. In relation to Case #1 , eight (8) <br /> groundwater monitoring wells, six (6) soil-vapor extraction wells, and five (5) air-sparge <br /> wells are located at the site. In relation to Case #2, ten (10) groundwater monitoring wells, <br /> four (4) dual-phase extraction wells, and one (1) shallow soil-vapor well are located at the <br /> site. <br /> 837 Shaw Road • Stockton, CA 95215 <br /> Telephone (800) 511-9300 • Fax (888) 445-8786 <br /> An Employee-Owned Company <br />
