soil samples will be analyzed ;for Total .Petroleum Hydrocarbons <br /> (TPH, CA DHS/LUFT) , and Benzene, Toluene, !_Ethylbenzene, and <br /> Xylenes (BTEX, EPA Method 8020) . <br /> 5.0 REMEDIATION OF CONTAMINATION <br /> Any soils contaminated above CA DHS guidelines discovered <br /> along the . pipeline will require excavation and treatment or <br /> disposal. USPCI `will provide all personnel and equipment for the <br /> 7 <br /> excavation and will subcontract1transportation .of the material to <br /> an approved :site �for treatment or disposal. Verification sampling <br /> and analysis of ni:.ative soils will, .be .required after excavation of <br /> all suspected contamination. When, the pipeline has been assessed, <br /> a detailed work pian for remediation will be developed. <br /> 6. 0 PIPELINE CLOSURE <br /> During the soil remediation phase, it is likely that sections <br /> of the i eline will be removed. Remaining sections of the lite <br /> P• P <br /> will be closed by grouting in :place. Discussions with concrete <br /> pumping contractors has revealed limits to the distances that grout <br /> can be pumped. In order to ensure that the Jine is completely <br /> grouted, it wily be necessary to expose and break the line every <br /> 750 - 1000 feet.: USPCI personnel will expose and break the line <br /> and attach the necessary couplings. A subcontracted ;concrete. <br /> pumping company will pump the grout into place. USPCI will obtain <br /> wpipeprop.doc f 4-- <br />
