L ✓ \..� <br /> WORK PLAN FOR SITE CHARACTERIZATION <br /> 303 SOUTH CHEROKEE LANE <br /> LLODI, CALIFORNIA <br /> L - <br /> 1.0 INTRODUCTION <br /> LThis work plan is for the assessment of soils containingpetroleum product constituents <br /> P P is <br /> (PPCs) at 303 South Cherokee Lane, Lodi, San Joaquin County, California (site). <br /> LPreparation of this work plan was authorized by Mr. Lloyd Gums, site owner. <br /> This work plan was prepared by the Environmental Services Division of The Twining <br /> LLaboratories, Inc. (Twining) in Modesto, California. <br /> L2.0 PURPOSE AND SCOPE <br /> L The purpose of this project is to characterize soils containing selected PPCs in the vicinity <br /> of the northern dispenser island (along Lodi Avenue) and to collect and analyze <br /> confirmation soil samples beneath the former locations of two gasoline underground storage <br /> tanks (USTs) and one diesel UST. The following scope of work is proposed to meet the <br /> objectives stated above: <br /> L • Drill one angle soil boring and two vertical soil borings in the vicinity of the northern <br /> dispenser island to assess the vertical and lateral extent of soils containing PPCs; <br /> • Drill six vertical soil borings to approximately 20 feet below site grade (BSG) at the <br /> former UST locations; <br /> L Analyze selected soil samples for total petroleum hydrocarbons as gasoline (TPH-G), <br /> benzene, toluene, ethylbenzene, total xylenes (BTEX), and total petroleum <br /> hydrocarbons as diesel (TPH-D); and <br /> LPrepare a report documenting field activities and presenting findings, evaluations, <br /> and conclusions. A site location map, site plan showing soil boring locations, final <br /> Lboring logs, and stratigraphic cross-sections (if appropriate) will be included. <br /> It is Twinings opinion that the above-referenced scope of work is the minimum required <br /> L to meet the stated objective. This scope of work would expand in the event that PPCs are <br /> detected through the field screening process. The approach and rationale for an expanded <br /> scope of work are described in section 4.1. <br /> L <br /> L <br />
