EXECUTIVE SUMMARY <br /> MAY 1 8 1992 <br /> This report documents results of soil vent and aquifer tsstif IRWit lit !,. tySA � <br /> q �i�ft�u��d;{f�yAegis <br /> Environmental, Inc., and discusses design for a remediation system to be installed at <br /> 1399 East Yosemite Avenue in Manteca, California, currently occupied by Frank's <br /> Exxon #2. <br /> The selected remediation technology for this site will remove and destroy petroleum <br /> hydrocarbons from both soil and groundwater. <br /> The remediation system consists of BSI's "S.A.V.E. System," and includes an internal <br /> combustion (IC) engine, a power take off, a vacuum pump, air compressor, and a water <br /> pump. Petroleum hydrocarbons in soil will be removed by vapor extraction, and <br /> consumed by the IC engine. The air compressor will drive a pneumatic groundwater <br /> pump in well MW-113. The pumped water will be heated by the engine to increase the <br /> volatility of dissolved hydrocarbons. The heated water will be sprayed into an aeration <br /> tank where the hydrocarbons in the water are volatilized and drawn into the vacuum <br /> stream for consumption by the IC engine. The treated water will be pumped through a <br /> flow meter and carbon canisters before being discharged, via underground piping, to an <br /> existing storm sewer. <br /> Fuel for the system will be provided by the hydrocarbons drawn from the soil, and <br /> supplemented with propane, when necessary, during the first 6 months of operation. <br /> Equipment will be located within a 6-foot-high, chain-link fenced enclosure with a locking <br /> gate. A fire extinguisher and a weather-proof document box will be located within the <br /> enclosure. System controls on the pump include a low-water shut off switch and a high- <br /> water start switch. Ports for sampling water are located in the influent and effluent lines. <br /> Vapor ports are located in the vapor intake line, before the vacuum pump and before and <br /> after the catalatic converters. <br /> Effluent rates will be monitored by a flow meter and the rate of flow will be controlled by <br /> a valve located on the discharge side of the spray aerator. During system start-up, it is <br /> proposed that effluent water samples be collected daily for the first 3 days of operation, <br /> then weekly for a period of 1 month. Thereafter, quarterly effluent samples will be <br /> collected and documented in quarterly monitoring reports. Air samples will be collected <br /> during the first 3 days, then weekly for a period of 1 month, then monthly until the system <br /> is shut down. Each sampling event will be documented in quarterly monitoring reports. <br /> The system will be constructed, maintained, and operated according to all federal, state, <br /> and local, guidelines, statutes, laws, and permit requirements. All discharges resulting <br /> from the operation of the system will be permitted, monitored, and reported as required. <br /> If the system is found not to be in compliance with air or water discharge requirements, <br /> the system will be shut down until appropriate modifications can be completed. <br /> 90-098.SU M <br />
