Mr John Benedict Project 880-039 1A ' October 22, 2001 Page 4 Operational Status The treatment system operational uptime was 100 percent during the third quarter 2001 The treatment system was shut down on July 24, 2001 pending contract negotiations Treatment system field data sheets are presented in Appendix D System Performance Status During the third quarter 2001, the system TPH-g emissions were maintained below 0 01 pounds per day, well below the allowable 6 1 pounds per day as specified by the permit to operate TPH-g destruction efficiency was 95 0 percent The benzene destruction efficiency was maintained at 100 percent The burn chamber temperature was ranged from 650°F to 850°F, well above the minimum burn temperature of 600°F as specified by the permit to operate System performance data is summarized below and in Tables D1 through D3, (Appendix D) Calculations for system removal rate, destruction efficiency, and emissions are presented in Appendix D Third Quarter 2001 System Performance Summary Pounds TPH-g removed since startup 2,396 Pounds TPH-g removed during this reporting period 9 TPH-g daily removal rate during reporting period(pounds per day) 007 TPH-g destruction efficiency(%) 950 TPH-g emission rate to atmosphere(pounds per day) <0 01 Pounds benzene removed since startup 26 Pounds benzene removed during this reporting period 00 Benzene Destruction Efficiency(%) 100 Benzene emission rate to atmosphere(pounds per day) <0 00003 Average flow rate for this reporting period(acfm) 40 System operational uptime during this reporting period(%) 100 CONCLUSIONS ' Analytical results of collected groundwater samples from MW-1 R were generally consistent with previous sampling events Groundwater elevation decreased 143 feet from the previous sampling event (May 2001) The observed groundwater gradient was 0 002 ft/ft to the sout Cas • IT CORPORATION SAC W\sacflPV20011PRAP1818800391A lab da 00'ut 1 (01010000)
