File No. 20-3978-0 LWR6 k" KLEINFELDER <br /> November 19, 1996 <br /> ATTACHMENT A <br /> SCOPE OF WORK <br /> RAILROAD SPUR SAMPLING AND ANALYSIS <br /> (PHASE I ESA RECOMMENDATION NUMBER 21) <br /> FORMER SPRECKELS SUGAR PLANT <br /> 18800 S. SPRECKELS ROAD <br /> MANTECA, CALIFORNIA <br /> 20-3978-O1.WR6 <br /> November 19, 1996 <br /> INTRODUCTION <br /> The Manteca Sugar Factory was constructed in 1917 and has been operated by Spreckels <br /> Sugar Company (Spreckels) since its construction. Railroad spurs have been located on <br /> site since the construction of the factory. Various herbicides or waste oil may have been <br /> used for weed control along the railroad tracks. Hazardous substances may have been <br /> transported on site via railcars. Creosote and/or pentachlorophenol may have been used <br /> to treat the railroad ties in the railbed. Locomotive maintenance was conducted on site <br /> wherever necessary. Polychlorinated biphenyls (PCBs), oils, and solvents may be <br /> associated with said maintenance. <br /> SCOPE OF SERVICES <br /> Kleinfelder proposes to visually inspect the railbed for obvious signs of contamination <br /> such as staining, and collect soil samples along the railbed. The soil samples will be <br /> collected using a hand auger and slide hammer sampler. The samples will be collected at <br /> the surface and at a depth of five feet below grade. The surface soil samples will be <br /> collected from 27 locations spaced at approximate 300 foot intervals on alternating sides <br /> of the railbed. The deeper five foot samples will be collected wherever soil staining is <br /> noted, or at eight randomly selected locations. The proposed sampling locations are <br /> shown on Plate 2. The hand auger borings will not require permits from the San Joaquin <br /> County Public Health Services Department Environmental Health Division (PHS/EHD). <br /> 20-3978-01.WR61MI3960138 Page 1 of 0/996, Klernfelder, Inc. <br />
