Third Quarter 2004 Groundwater Monitoring)Remediation Status Report <br /> lR ` Moore Petroleum Bulk Plant,5491 F Street,Banta,California <br /> Page 6 <br /> REMEDIATION SYSTEM SUMMARY <br /> Soil Vapor Extraction System l <br /> System description: <br /> Petroleum vapors are extracted from the subsurface through three monitoring/vapor wells (VEW- <br /> 3/MW-8, MW-1, and VEW-4/MW-7) and two vapor extraction wells (VEW-1 and VEW-2). The <br /> wells are manifolded together with PVC piping in the remediation compound before connecting <br /> to the extraction system. The vapor extraction system is a 5-horsepower regenerative blower <br /> manufactured by Rotron-Ametek®, Model number EN6F72L. Abatement of the volatile organic <br /> compounds extracted with the SVE system is activated carbon adsorption. 'The system is <br /> operating under the authority of the San Joaquin Valley Air Pollution Control District, Authority <br /> to Construct No. N 560-8-0. The system is currently not operating pending district approval. <br /> System startup date: Pending <br /> Current system mode: Carbon abatement <br /> Active extraction wells: VEW-1 through VEW-4 <br /> Inactive extraction wells/reason: MW-1/system optimization, zero concentrations <br /> Status of system operation during reporting period/.reasons for downtime: <br /> From July 1 through September 13, 2004, the SVE system with the catalytic oxidizer(catox) <br /> operated continuously with the exception of one shut down due to a power outage. On <br /> September 13, the system with the catalytic oxidizer was shutdown and removed from site. The <br /> I <br /> SVE as previously described was installed and tested and remained shut down until the source <br /> test was performed on September 29, 2004. According to hour meter readings and field data,the <br /> catox system operated for a total of 57 days during this period. All effluent samples collected <br /> during this reporting period were non-detect for TPHg and benzene concentrations. <br /> Vapor Analysis Performed: <br /> Analysis Abbreviation Designation USEPA Method No. <br /> Total Petroleum Hydrocarbons TPH Gas-Range 826(18 <br /> as Gasoline g Hydrocarbons <br /> Benzene Aromatic <br /> Toluene BTEX Volatile 8260E <br /> Eth lbenzene Organics <br /> X lenes Total} <br /> Methyl Tertiary Butyl Ether MTBE Fuel 82606 <br /> Oxygenate <br /> �r <br /> t <br /> I <br />
