S REMEDIATION SYSTEM'S OPERATION <br /> OVERVIEW <br /> PumI2 and Treat System <br /> The P&T system was turned off by ASE personnel on February 28, 2002 <br /> That system no longer operates <br /> Air-Snarging/Vapor-ExtractionS System <br /> The ASNE system operated continuously during the month of March 2002 <br /> except for brief periods of downtime for periodic, scheduled <br /> maintenance <br /> Efate <br /> While operating, the system infected an average of 52 cubic feet per <br /> minute (cfm) of air into the 7 AS well manifold, and extracted an average <br /> of 74 cfm of petroleum-hydrocarbon laden air from the 7 VE well <br /> manifold The IC engine operated typically at 1800 RPM <br /> • Maintenance <br /> The IC engine was turned off each 220 to 250 hours of operation to <br /> perform routine maintenance activities Scheduled maintenance included <br /> lube, oil and filter for the engine and blowers, and draining of t h e <br /> moisture knock-out drum <br /> INFLUENT AIR SAMPLE COLLECTION AND <br /> ANALYSES <br /> Influent Air Sample <br /> On March 25, 2002, ASE collected an influent air sample (INF-VE- <br /> 03 25 02) from the manifold of the 7 VE wells This sample was analyzed <br /> by Kiff Analytical of Davis, California (FLAP #2236) for total petroleum <br /> hydrocarbons as gasoline (TPH-G), benzene, toluene, ethylbenzene, a n d <br /> xylenes (collectively known as BTEX), the five fuel oxygenates and lead <br /> scavengers by EPA Method 8260B The analytical results for this sample <br /> • are tabulated in Table One The influent air sample analytical report a n d <br /> chain of custody record is attached in Appendix A <br /> Frank's One Stop Remediation System Monthly Report — March 2002 <br /> -2- <br />
