If lead pollution is verified,the Discharger shall continue quarterly monitoring for dissolved lead. If the presence of dissolved lead is not confirmed,no further test is required. 'Fuel oxygenates,including MTBE,methanol,ethanol,tertiary butyl alcohol(TBA),tertiary amyl methyl ether (TAME),di-isopropyl ether(DIPE),and ethyl tertiary butyl ether(ETBE)shall be analyzed in all monitoring wells during two monitoring events in the first and third quarters. If results are nondetectable for fuel oxygenates for both sampling events,no further monitoring for oxygenates is required in that well. If a fuel oxygenate is detected,it shall be added to the quarterly monitoring program for the well in which it was detected. REPORTING When reporting data, the Discharger shall arrange the information in tabular form so that the date, the constituents, and the concentrations are.readily discernible. The data shall be summarized in such a manner as to illustrate clearly the compliance with this Order. In addition, the Discharger shall notify the Board within 48 hours of any unscheduled shutdown of any soil vapor and/or groundwater extraction system.
