sec®R <br /> • delivery under chain-of-custody to a laboratory certified by the State of California Department of <br /> Health Services Environmental Laboratory Accreditation Program to perform the specified tests. <br /> To help assure the quality of the collected samples and to evaluate the potential for cross <br /> contamination during transport to the laboratory, a distilled-water trip blank accompanies the <br /> samples in the cooler. The trip blank is analyzed for the presence of volatile organic compounds <br /> of concern. For petroleum hydrocarbons, the trip blank is typically analyzed for TPHg, BTEX, and <br /> MTBE by EPA Method 8260. <br /> Containment and Disposal of GeneratedNater/LPH <br /> Purge water generated during the field activities is temporarily stored within a polyethylene tank <br /> kept at the Tesoro Terminal. The purge water is typically pumped through the carbon filter <br /> system, stored in a second polyethylene tank at the Tesoro Terminal site, and sampled. Upon <br /> satisfactory analytical results from the samples, the water is then discharged into the sanitary <br /> sewer. <br /> Related Procedures: I <br /> Standard Procedure for Equipment Dedontamination <br /> • <br /> • <br /> STTC 1Q06 Final Report D-2 May 1,2006 <br /> 770T.43673.12.0002 <br />
