SACRAMENTO STREET <br /> LODI, CALIFORNIA <br /> OUR PROJECT NUMBER: E07087A <br /> 1.0 SUMMARY <br /> Neil 0. Anderson & Associates, Inc. (NOA) has been retained by Andy Stephens of A. M. <br /> Stephens Construction, to conduct a Limited Phase II Environmental Site Assessment for the <br /> property located at 1225 South Sacramento Street, Lodi, San Joaquin County, California. The <br /> property is planned for purchase. <br /> The subject property is located adjacent to Holz Rubber. Our office previously completed a <br /> Phase I Environmental Site Assessment (May 2007) in which we identified several areas of <br /> concern. Based on the Phase I, two possible USTs were located at the subject property and no <br /> records were located for the tanks' removal. In addition, the properties to the north, south and <br /> east are part of a known SLIC site (Holz Rubber). Impacts from the neighboring property may <br /> have migrated onto the subject property. This Phase II is intended to address concerns related <br /> to the potential for soil and soil vapor contamination from the Holz property and to probe the <br /> UST locations to identify if contamination is located near the tank pits. <br /> The San Joaquin County Environmental Health Department (EHD) requires a workplan be <br /> prepared before drilling permits can be issued for environmental investigations. A drilling <br /> permit will be required for the proposed borings near the possible underground storage tank <br /> locations, the exploratory boreholes and the soil vapor boreholes. <br /> The workplan is organized into the following sections: general information, health and safety <br /> plan, soil sampling procedures, proposed time schedule for work, and report preparation. We <br /> understand the investigation may not proceed until after EHD staff approval of the workplan <br /> and issuance of a drilling permit. A California licensed geologist and engineer will oversee the <br /> investigation on the site. <br /> 1.0 GENERAL INFORMATION <br /> 1.1 Soil Sample Purpose, Location, and Depth <br /> The basic purpose for collecting soil samples is to identify any impacts to on-site soils or soil <br /> vapors which may have occurred as a result of leakage from the possible underground storage <br /> tanks and to identify possible impacts from the adjacent properties. <br /> LODI • SACRAMENTO WALNUT CREEK • RENO • MODESTO <br /> L 0 D 1 902 Industrial Way Lodi,CA 95240 • 209.367.3701 • FAX 209.369.4228 <br />
