The First and Second QMRs discuss the groundwater <br /> monitoring events conducted in January and May 2001. The Second QMR recommends discontinuation <br /> of selected fuel oxygenates for various monitoring wells. <br /> We have the following comments on these reports: <br /> 1. The First and Second QMRs are titled"Semi-Annual,"but these report on quarterly, not semi- <br /> annual events. <br /> 2. The First QMR discusses the unusually high concentrations in various wells (i.e.,methyl tertiary <br /> butyl ether (MTBE) detections in monitoring wells MW-4 and MW-8), but the Second QMR <br /> does not discuss the continuing trends in these wells. Quarterly monitoring reports must discuss <br /> continuing trends in wells with uncharacteristic results from the previous quarter. <br /> 3. The Second QMR recommends discontinuing analysis for all fuel oxygenates, with the exception of <br /> MTBE, in two monitoring wells and various fuel oxygenates in five monitoring wells as listed in <br /> Table 3. Board staff concurs with the recommendations in Table 3 of the QMR. In accordance with <br /> Monitoring and Reporting Program No. 5-01-815, Equiva may implement the revised monitoring. <br /> The third quarter groundwater monitoring report is due by 30 October 2001.
