O <br /> 0 <br /> Soil Sampling Work Plan anteagroup <br /> Stockton, CA - SJRRC Property Exchange <br /> 1800 North Marshall Avenue <br /> Stockton, California <br /> 1.0 INTRODUCTION <br /> AnteaTmGroup has prepared this Soil Sampling Work Plan to outline a proposed scope of work to evaluate potential <br /> concerns for future railway workers on the property involved in a potential property exchange between Union <br /> Pacific Railroad (UPRR) and the San Joaquin Regional Rail Commission (SJRRC) near the intersection of Alpine <br /> Avenue and West Lane in Stockton, CA (Figure 1). Provided herein is a site summary, and a proposed scope of <br /> work. <br /> 1.1 Site Description <br /> The area of potential property transfer from the SJRRC to UPRR would include the 100 foot by approximately 1600 <br /> foot rectangular area west of the tracks, included in parcel number 11709014 (Figure 2). Buildings shown on <br /> Figure 2 have been razed, and the property is currently a vacant, dirt lot. The site is relatively flat, and lies at <br /> approximately 20 feet above mean sea level.Surrounding land use is commercial, industrial, protected agricultural <br /> (cemeteries)and residential. <br /> 1.2 Background <br /> The site's case extends to a larger 62 acre area including parcel numbers 117-090-01, 117-090-13 (OU 1), 117-090- <br /> 14, 125-360-04, 127-280-34 (OU-2) (Figure 2). The collective site was used for wood products manufacturing by <br /> several companies (Stockton Box Company, American Forest Products Company (AFPC), and American Moulding <br /> and Millwork Company(AMMO))from 1921 to 1993. During this time, petroleum products and solvents were used <br /> and stored onsite, and burn pits were used to dispose of some waste products. Numerous environmental <br /> investigations and remedial efforts have taken place across the site,and are summarized in AMEC Geomatrix Inc.'s <br /> (AMEC) October 6, 2009 report. MCD-Lazares, LLC (MCD) acquired the site out of bankruptcy in 2006, and <br /> committed to complete the required provisions of the Voluntary Cleanup Agreement for assessment and cleanup <br /> of structures and soil at the site. Concurrently, AFPC and the URS Corporation (URS) conducted groundwater <br /> remediation associated with former underground storage tanks at the site. MCD sold the site to the SJRRC in 2008 <br /> (AMEC 2009). <br /> A Human Health Risk Assessment (HHRA) prepared for the site was approved on December 17, 2007, and the <br /> addendum was approved on October 22, 2008. The HHRA established a risk based remediation goal (RBRG) for <br /> 2,3,7,8-tetrachlorodibenzo-p-dioxin(2,3,7,8-TCDD TEQ)of 0.220 pg/kg for a 1.0x10 5 cancer risk(DTSC 2008). <br /> 1 www.anteagroup.com <br />
