Readwell&Rollo <br /> 22 December 2003 'U4>, II!11Y7771111 <br /> Project: 2597.10 <br /> DED 2 6 Z003 <br /> Jeffery Wong ENVIRONMENT HEALTH <br /> San Joaquin County Environmental Division PERMIT/SERVICES <br /> 304 East Weber Street, Third Floor <br /> Stockton, California 95202 <br /> Subject: Investigation Workplan <br /> 424 North Van Buren Street (Chase West, Area 16) <br /> Stockton, California <br /> Dear Mr. Wong: <br /> This workplan describes the well destruction proposed for 424 North Van Buren Street (Figure <br /> 1). Treadwell & Rollo has been retained by the City of Stockton to coordinate the environmental <br /> issues at this site and three other sites within the North Shore Banner Island project currently <br /> being supervised by the San Joaquin County Environmental Health Department (SJCEHD) in the <br /> underground storage tank program. The other three sites are: <br /> 1. 420 North Madison Street (Carando) <br /> 2. 423 North Madison Street (Chase East) <br /> 3. 404 West Fremont Street (Crystal Creamery), <br /> Treadwell & Rollo and City of Stockton representatives met with you and Margaret Lagorio on 5 <br /> December 2003 and discussed the planned Banner Island Northshore redevelopment and how it <br /> will impact these four sites. <br /> BACKGROUND <br /> This site was originally developed in the early 1900s and re-developed sometime after the mid <br /> 1960s for use as an auto dealership. Currently the site has several buildings which are vacant. <br /> Areas between buildings are mostly unpaved, but there are areas of pavement or are covered with <br /> concrete slabs (Figure 1). The Site is enrolled in the Underground Storage Tank cleanup fund. <br /> A 1,000 gallon UST which reportedly stored gasoline and diesel, identified as Tank No 7, was <br /> removed in 1986 and petroleum hydrocarbon contamination was documented during the <br /> removal. A free product skimmer was used at MW-3, located adjacent to the former UST <br /> location from prior to 1994 until 1996. A soil vapor extraction system, including 23 air sparging <br /> wells, began operation in November 1999 and operated until February 2001. In June 2003 an <br /> ozone sparging system with 17 wells began operation began operation at the site. <br /> Treadwell&Rollo,Inc.Environmental&Geotechnical Consultants <br /> 555 Montgomery Street,Suite 1300,San Francisco,CA 94111 <br /> Telephone(415)955-9040 Facsimile(415)955-9041 <br />
