" <br /> SVE System Start up and Operation <br /> Stratus proposes'to conduct system start=up and source testing programs for the proposed SVE <br /> remediation system during the first 2 days of system operation. Thd following parameters will <br /> be monitored and recorded on field data sheets during the system start"up: <br /> • Vapor extraction rate, <br /> • Applied vacuum at.each vapor extraction well, <br /> • Influent flow in to the system, and <br /> • PID measurements for organic vapors from the extraction wells. <br /> JI <br /> During the source testing, one set of influent and effluent air samples will be collected and <br /> forwarded to a state-certified laboratory for analysis. The air samples will be analyzed on a 24- <br /> hour turnaround basis for total petroleum hydrocarbons as Gasoline (TPHG) by United States <br /> Environmental Protection Agency (USEPA) Method 8015, and for benzene, toluene, <br /> ethylbenzene, and total xylenes (BTEX) and methyl tertiary butyLi ether (MTBE) by USEPA <br /> Method 8260. Analytical. results will be used to -calculate the destruction efficiency of the <br /> system. Manufacturer's literature states that the destruction efficiency for the system for <br /> petroleum hydrocarbons is 95-99.99 percent. F <br /> Stratus will prepare, and submit to San Joaquin Valley Unified Air Pollution Control District, a <br /> source test report presenting the analytical results ofyapor samples, tabulated field observations, <br /> and destruction efficiencies of the system. <br /> If you have any questions, please contact Gowri Kowtha at (530) 676'6001. <br /> Sincerely, <br /> OTRATU5 ENVIRONMENTAL, INC. <br /> . ` <br /> i Kiran Nagaraju Go ri S.
