This work plan has been <br /> prepared in response to your letter, dated April 9, 2001 (Attachment A), requesting a <br /> CAP to evaluate potential options for remediating petroleum hydrocarbon impacts to <br /> groundwater beneath the site. During your telephone conversation with Mr. William <br /> Brasher of SECOR on May 1, 2001, it was agreed that the appropriate first step for <br /> preparing a CAP would be the performance of feasibility testing. Therefore, this work <br /> plan fulfills the requirement of your April 9, 2001 letter. <br /> This work plan includes a brief discussion of site background and previous <br /> investigations, proposed scope of work, and schedule. <br /> SITE BACKGROUND <br /> The site is an operating Chevron Service Station located on the northwest corner of <br /> Washington Street and South Center Street in Stockton, California, and is within an area <br /> of primarily commercial use (Figure 2).
