i <br /> (,;Soil Vapor Extraction and Air Sparging <br /> Performance Monitoring Plan <br /> Stockton Yard Maintenance Facility,Stockton <br /> r Page 3-2 <br /> blower motor contactor installed in the oxidizer control panel. . <br /> C. Check for tripped breaker at the electrical panel breaker box. <br /> d. Verify that blower has voltage at the motor starter coil. <br /> Problem: Low exotherrrm. llhen operating range<100T(<38'C) between the oxidi f'er inlet and outlet. <br /> Potential Solutions: <br /> a. Check for excess dilution air. <br /> b. Check influent concentrations. Optimize SUETS to increase influent concentrations. <br /> C. Check catalyst performance and destruction removal efficiency. <br /> Problem: High outlet tem <br /> peratu% >975°F(>524°C) <br /> Potential Solutions <br /> a. Reset High Temperatute switch. <br /> b. Increase dilution air. <br /> C. Decrease soil vapor flow. <br /> Problem: High effluent concentrations, >5%of influent loading <br /> Potential Solutions: <br /> a. Shut down system and notify regulator if permit conditions are exceeded. <br /> b. Check influent concentrations. Try to maximize influent soil concentrations by closing <br /> manual dilution air valves and extract from higher.concentration wells. <br /> C. Replace catalyst. <br /> d. Contact manufacturer to inquire about raising oxidizer inlet set-point temperature. <br /> Problem: Catalytic oxidiser systemciency, <95% <br /> Potential Solutions: <br /> a. Check operational parameters such as inlet set-point, temperature <br /> b. Shut down system and notify regulator if permit conditions are exceeded. <br /> C. Resample system. <br /> 3.2 System Optimization and troubleshooting for AS <br /> This section provides guidance for operating the AS according to design criteria. Only typical AS <br /> operational problems are addressed. Operational problems outside the scope of this section should <br /> be referred to the project engineer, project manager,.or equipment manufacturer. <br /> DAPMMtockton Yard PMP.doc <br />
