GROUND ZERO ANALYSIS, INC. <br /> 1714 Main Street <br /> Fscalon,California 95320-1927 <br /> Telephone: (209)838-9888 <br /> Facsimile: (209)838-9883 MAR 1 <br /> 12005 <br /> E"RONMENT HEALTH <br /> March 11, 2005 PERMIT/SEIRV7CES <br /> Mr. Harlin Knoll <br /> San Joaquin County Environmental Health Department <br /> 304 E. Weber Ave., Third Floor <br /> Stockton, CA 95202 <br /> Subject: Workplan for Soil Boring Investigation <br /> Former Tiger Lines Truck Yard, 1430 Cherokee Lane, Lodi, CA(Figure 1) <br /> Dear Mr. Knoll: <br /> We are writing on behalf of LTS Rentals to present a workplan for a Phase II investigation at the <br /> subject property. The site previously operated multiple above ground storage tanks (ASTs) in a <br /> containment unit (Figure 2). The proposed work is intended to evaluate whether soil and <br /> groundwater have been impacted by previous site activities. In addition, if contamination is <br /> present, the proposed work is intended to delineate the vertical and horizontal extent of the <br /> contamination. The work is in anticipation of the possible lease of the property. <br /> Workplan <br /> We propose to conduct the following scope of work: <br /> • Utilize C-57 licensed Fisch Environmental to advance four(4) soil borings to maximum depths <br /> of 50-55 feet below grade using a direct push drill rig. Upon completion the borings will be <br /> backfilled to the surface with neat cement grout. The proposed boring locations are shown on <br /> Figure 2. <br /> • Collect soil samples at five-foot intervals for lithologic identification, field screening, and <br /> possible laboratory analysis. In addition, one groundwater sample will be collected from each <br /> boring. <br /> • Submit selected soil samples (up to five per boring) and groundwater samples to a state- <br /> certified laboratory for analysis of total petroleum hydrocarbons as gasoline (TPHg) and diesel <br /> (TPHd) and benzene, toluene, ethylbenzene, and total xylenes (BTEX). Selected samples will <br /> also be analyzed for gasoline oxygenate additives. <br /> All work will be conducted in accordance with Ground Zero's Quality Assurance/Quality Control <br /> Plan(Attachment A) and our Site Specific Health and Safety Plan (Attachment B). <br />
