MONITORING AND REPORTINu PROGRAM NO. <br />Woolsey Oil Company <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 />11 <br />SAMPLING FREQUENCY' <br />Maximum <br />Quarterly <br />Semi-annually2 <br />Wells <br />MW -3 MW -5 MW -6 MW -7 <br />MW -9 New Wells <br />MW -11) MW -2 MW -4 <br />MW -8 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 />11 <br />1 For nondetectable results. <br />2 If dissolved lead is detected, the Discharger shall perform verification sampling within 30 days of submittal <br />of the monitoring report. If lead pollution is verified, the Discharger shall continue quarterly monitoring for <br />dissolved lead. If the presence of dissolved lead is not confirmed, no further test is required. <br />3 Fuel 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. 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 a VOC is detected, it shall be added to the quarterly monitoring program for the well in which it was <br />detected. If VOCs are present in the future oxygenate analysis chromatographs, then the VOCs shall be <br />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/l <br />as diesel <br />Total Petroleum Hydrocarbons <br />8015M <br />50 µg/1 <br />as gasoline <br />Dissolved Lead <br />7421 <br />10 µg/l <br />MTBE' <br />8260B <br />0.5 µg/1 <br />TBA' <br />8260B <br />0.5 µg/l <br />DIPE' <br />8260B <br />0.5 µg/l <br />TAME' <br />8260B <br />0.5 µg/1 <br />ETBE' <br />8260B <br />0.5 µg/1 <br />Methanol' <br />8260B <br />100 µg/1 <br />Ethanol' <br />8260B <br />50 µg/1 <br />Volatile Organic Compounds4 <br />8260B <br />0.5 µg/1 <br />1 For nondetectable results. <br />2 If dissolved lead is detected, the Discharger shall perform verification sampling within 30 days of submittal <br />of the monitoring report.
