KLEINFELDER <br /> On December 26-27, 1996 and January 13, 1997, twenty-seven (27) soil sampling locations along <br /> the railroad spurs were evaluated. During our field work, Kleinfelder collected a total of thirty-two <br /> (32) soil samples from the 27 locations. Twenty-eight (28) of the 32 samples were subsequently <br /> analyzed. The 28 soil samples were analyzed for one or more of the following analytes: <br /> • CAM 17 Metals by EPA Methods <br /> • Total Extractable Petroleum Hydrocarbons as Referenced to Diesel and <br /> Lubricating Oil by EPA Method 3550.and LUFT Method <br /> • Organochlorine Pesticides and PCBs by EPA Method 8080 <br /> • Chlorinated Herbicides by EPA Method 8150 <br /> • Semi-Volatile Organics by GC/MS by EPA Method 8270, including Tentatively <br /> Identified Compounds (TICS) <br /> Based on the results of the subsurface assessment, Kleinfelder recommended no "further <br /> investigation or clean-up of the railroad spur locations with exception of an isolated area of high <br /> soluble lead (58 mg/L at a depth of 0.5 feet). Kleinfelder recommended that this area of soluble <br /> lead concentrations which exceed the STLC-Regulated Level be excavated and properly disposed <br /> of to improve property marketability. Confirmation soil samples using STLC-Lead analysis <br /> should be obtained to verify the adequacy of excavation(<5 gg/kg)." <br /> During a August 26, 1997 discussion with Mr. Ron Rowe of PHS/EHD, it was decided that <br /> additional delineation of the area should be accomplished prior to excavation. That proposed <br /> additional delineation is outlined in this proposal as follows. <br /> 20-3978-01.W 32/2017P 110 Page 4 of 7 <br /> ® 1997 Kleinfelder,Inc. August 28, 1997 <br />
