1 <br /> ' SOIL REMEDIATION <br /> WORK PLAN <br /> 6540 E JAHANT ROAD <br /> ACAMPO, CALIFORNIA 95220 <br /> ' 1 0 INTRODUCTION AND BACKGROUND <br /> This work plan has been prepared to provide a detailed discussion of the planned remedial activities <br /> for the site located at 6540 E Jahant Road in Acampo, California <br /> The site resides in a rural area northeast of the city of Acampo The property is used for <br /> agricultural and residential purposes The location of the site is shown on Figure I <br /> In 1946, a 300 gallon underground fuel storage tank was installed on the property The tank was <br /> used for the fueling of both farming equipment and personnel vehicles Use of the tank continued <br /> ' through 1986 when it was removed from service During the operating period for the tank, both <br /> leaded and unleaded gasoline were stored in it <br /> On July 17, 1991, the underground storage tank was removed The tank was visually observed to <br /> be in poor condition and petroleum hydrocarbon odors were noticed within the excavation <br /> overburden Soil sampling of the tank excavation bottom sod was conducted The analysis of the <br /> soils samples indicated a significant presence of petroleum hydrocarbon compounds within the <br /> ' soils <br /> Subsequent over-excavation of the tank area has removed all of the in place impacted soils These <br /> soils were stockpiled onsite and amounted to approximately 600 cubic yards (cu yds) Soil samples <br /> bk were collected from these stockpiled soils The analytical results for the soil stockpile samples are <br /> enclosed as Appendix A These results indicated that the stockpiled sods contained total petroleum <br /> ' hydrocarbon compounds as gasoline in concentrations up to 907 milligrams per kilogram (mg/kg) <br /> Varying levels of Benzene, Toluene, Xylene and Ethyl-benzene (BTX&E) were also detected in these <br /> sods No EDB was detected in these sods In order to completely remediate the site, the property <br /> owner contacted TreaTek Inc (TreaTek) to evaluate available remedial options and to conduct the <br /> ' remediation <br /> It was determined, based on the sod characteristics, the compound concentrations and the available <br /> ' area at the site, that remediation via biological means would be the most effective and expeditious <br /> remedial alternative <br /> ' The following sections of this report provide a description of TreaTek's planned site remedial <br /> activities <br /> 20 SCOPE OF WORK <br /> ' TreaTek intends to remediate the onsite sods containing petroleum hydrocarbon residues via <br /> biological means Biological remediation of petroleum hydrocarbon residues in soils is a widely <br /> ' accepted and effective technology A description of this technology as well as a treatment system <br /> description and a detailed discussion of the planned remedial activities are contained in the <br /> following sections <br /> 1 <br /> 1 <br /> 1 <br />
