U necessary, affected soil may be relocated to a nearby location <br /> for temporary storage. <br /> Samples of stockpiled soil will be collected to assist in the evaluation of potential <br /> disposal/reuse options. Typically, a three -point composite soil sample will be collected for <br /> every 750 cubic yards of soil. Samples will be sent to the laboratory in separate containers <br /> and the laboratory will composite the three samples into one before performing analysis, <br /> Soil samples will be collected following standard environmental prorocols. Sample <br /> containers will be labeled, stored in an ice-cooled chest, and transported to a California- <br /> certified laboratory,under chain-of-custody procedures. <br /> Soil samples typically will be analyzed for the following constituents: total petroleum <br /> hydrocarbons (TPH) quantified as crude (TPFJc)using U.S.Environmental Protection <br /> Agency(EPA)Method 8015M; benzene, toluene, ethylbenzene, and xylenes(BTEX) using <br /> EPA Method 8021; polyaromatic hydrocarbons (PAHs)using EPA Method 8270 SIMS, and <br /> CAM 17 metals using EPA Methods 6000/7000 series. <br />
