If pre-characterization suggests offsite disposal to a Class T facility then direct-loading <br /> should not be performed. Instead, additional sampling and segregation of stockpiles <br /> should be performed to minimize costs related to hazardous waste disposal. <br /> 4. Since groundwater may be located within 40 h bgs, it is possible that groundwater has <br /> been affected by the release. Cambria recommends that concurrent with delineation of the <br /> vertical impact to vadose zone soil, groundwater samples be collected within the most <br /> affected area(s) of the Site and immediately downgradient. Cambria expects that grub <br /> groundwater sampling (using dual-tube direct push technology or other techniques to <br /> help prevent sample contamination by the overlying impacted soils) or temporary wells <br /> would provide sufficiently accurate analytical results. <br /> 5. Sampling within 25 ft of the pipeline will require pot-holing to the pipeline at either end <br /> of the work area. After pot-holing two locations, the surface trace can be approximated <br /> with a chalk line or rope,and the pipeline should be clearly marked in the field. <br /> CLOSING <br /> Please call Bob Schultz at(510)420-3341 with any questions or comments. <br /> Sincerely, <br /> Cambria Environmental Technology, Inc. <br /> RoberL W. `hultz, R.CI. <br /> Senior Project.Geologist <br /> Cc' Mr. Charles Spatafore,4720 S.Lammers Road,Tracy, California 95377 <br /> Mr.Bob Gondek,Chevron Pipe Line Company. 2811 Hayes Road,Houston, <br /> Texas 77082 <br /> Mr.Doug Heard,Kleinfelder,Inc.,2825 E.Myrtle Street, Stockton,California <br /> 95205 <br /> [L\e-0ar ,Pipe Gne\Zicy KLM MP151.5ftAlllcdp307414-w kplm,mmmenLs.d. <br /> TOTAL P.03 <br />
