MONITORING AND REPORTL r PROGRAM NO. R5-2002-0827 <br />Woolsey Oil, Inc. <br />San Joaquin County <br />TABLE 1 <br />-2- <br />1 All wells will be monitored quarterly for water levels and the presence and thickness of free product. <br />2 Wells will be sampled semi-annually during the second and fourth quarters. <br />3 MW -6 will be analyzed for volatile organic compounds (VOCs) for one year (four quarters). If VOCs are <br />not detected during that year, then VOCs sampling will stop for MW -6. <br />° MW -7 will be sampled quarterly for fuel oxygenates, and semi-annually for all other constituents. <br />SAMPLING FREQUENCY' <br />Maximum <br />Quarterly <br />Semi-annually2 <br />Wells <br />MW -3 MW -5 MW -6 MW -7 <br />MW -8 MW -9 MW -1D New Wells <br />MW -2 MW -4 MW -10 <br />1 All wells will be monitored quarterly for water levels and the presence and thickness of free product. <br />2 Wells will be sampled semi-annually during the second and fourth quarters. <br />3 MW -6 will be analyzed for volatile organic compounds (VOCs) for one year (four quarters).

If results are nondetectable for fuel oxygenates in all wells, no <br />further monitoring for oxygenates is required. If a fuel oxygenate is detected, it shall be added to the quarterly <br />monitoring program for the well in which it was detected. <br />4 If VOCs are detected in a fuel oxygenate chromatograph, VOCs shall be added to the quarterly monitoring <br />program for the well in which it was detected, and reported. <br />Analytical <br />Maximum <br />Constituent <br />Method <br />Detection Limit' <br />Depth to water <br />---- <br />---- <br />Benzene <br />8020 or 8260B <br />0.5 µg/1 <br />Toluene <br />8020 or 8260B <br />0.5 µg/1 <br />Ethylbenzene <br />8020 or 8260B <br />0.5 µg/1 <br />Xylenes <br />8020 or 8260B <br />0.5 µg/1 <br />Total Petroleum Hydrocarbons <br />8015M <br />50 µg/1 <br />as diesel2 <br />Total Petroleum Hydrocarbons <br />8015M <br />50 µg/1 <br />as gasoline <br />MTBE' <br />8260B <br />0.5 µg/1 <br />TBA' <br />8260B <br />0.5 µg/1 <br />DIPE' <br />8260B <br />0.5 µg/1 <br />TAME3 <br />8260B <br />0.5 µg/1 <br />ETBE3 <br />8260B <br />0.5 4g/1 <br />Methanol' <br />8260B <br />100 µg/1 <br />Ethano13 <br />8260B <br />50 µg/1 <br />Volatile Organic Compounds4 <br />8260B <br />0.5 µg/l <br />1 For nondetectable results. <br />2 Only MW -6 will be analyzed for TPH-d. <br />3Fuel oxygenates, including MTBE, methanol, ethanol, tertiary butyl alcohol (TBA), tertiary amyl methyl <br />ether (TAME), di -isopropyl ether (DIPE), and ethyl tertiary butyl ether (ETBE) shall be analyzed in all <br />monitoring wells during one monitoring event.
