Based on the WEGE data, which will be confirmed during an air sparge and SVE pilot <br /> test, the system proposed will be sized at approximately 100 cfm capacity. <br /> 4.1.3 System Overview <br /> Pinnacle_proposes to-connect to existing groundwater monitoring wells S-1, and S-2. In <br /> addit'on, an air sparge well ,will be installed adjacent to S-1 to evaluate the effectiveness <br /> of air sparging at the site. Based on the data provided in the WEGE SVE pilot test, air <br /> sparging should be effective at addressing the dissolved phase hydrocarbons at the site. <br /> The soil vapor extraction and air sparge wells will be connected to the SVE/AS systems <br /> via subsurface conveyance piping to the treatment system compound. The compound <br /> will consist of piping manifolds, SVE/AS equipment, and electrical equipment. <br /> The proposed treatment system will consist of a catalytic oxidizer unit capable of <br /> approximately 100 cubic feet per minute of air flow and a destruction removal efficiency <br /> greater than 95%. <br /> 4.2 Equipment <br /> • The remediation system will utilize the equipment discussed in section 4.1.3. The <br /> equipment proposed is all standard equipment for the industry and will provide long term <br /> operation for the system. The total cost of the equipment necessary for completing the <br /> system is estimated at $50,000 not including the cost of construction. <br /> 4.3 System Operation and Performance Evaluation <br /> The system is proposed to operate twenty-four hours a day, every day of the year. The <br /> extracted soil vapor will be treated and discharged to the atmosphere under a permit to <br /> operate to be issued by S.IVAPCD. The operational performance of the system will be <br /> monitored on a monthly basis with soil vapor samples collected from the influent, and <br /> effluent of the system. The status of the system will be reported in the quarterly <br /> groundwater monitoring and operation and maintenance report. <br /> 4.4 Implementation Schedule <br /> The proposed implementation schedule for installing the SVE/AS system is presented in <br /> Figure 5. However, the permit application process may take several weeks to accomplish <br /> and the actual start date of the system will depend upon the receipt of the authority to <br /> 4-2 <br /> k51:1E:1USA100651REPORTS10065P201.DOC-98Vsg:1 Rev.0, 1126199 <br /> 20A41-007.001 <br />
