f L) MONITORING AND REPORTING PROGRAM NO.R5-2003-0044 _4_ GENERAL ORDER FOR LAND DISPOSAL OF GROUNDWATER OR SURFACE WATER FROM CLEANUP OF PETROLEUM FUEL POLLUTION volumes of extracted groundwater and product, gradient maps, remediation system operational information, and recommendations/conclusions must be included. All monthly information obtained during the calender quarter is to be included in the respective quarterly report. REPORTING Annually, by 30 January, the Discharger shall submit to the Regional Board a report evaluating the effectiveness and progress of the groundwater cleanup, including at a minimum: both tabular and graphical summaries of the monitoring data obtained during the previous year; trends in the concentrations of the pollutants in groundwater monitoring wells; whether the contaminant plume is being captured by the extraction system or is continuing to spread; plans for improvements to the groundwater monitoring, extraction or treatment system; status of any other cleanup activities such as soil excavation or soil venting systems; and the anticipated date for completion of cleanup activities. The annual report shall also include the reasons for and durations of all interruptions in the operation of the treatment systems. Quarterly monitoring reports shall be submitted to the Regional Board by the 30th day of the month following the end of the calendar quarter. In reporting the monitoring data, the Discharger shall arrange the data in tabular format so that the date, the constituents, and the concentrations are readily discernible. The data shall be summarized in such a manner to illustrate clearly the compliance with Waste Discharge Requirements. Monitoring Reports will also include an evaluation of the ground water cleanup progress, trends, monitoring well analyses and plume containment. If this evaluation is already submitted to the Regional Board in a separate groundwater monitoring report, then the Discharger may reference the date and title of the most recent report in lieu of including it with the monitoring report required under this Order. In addition, the Discharger shall discuss the compliance record and the corrective actions taken or planned, which .may be needed to bring the discharge into full compliance with Waste Discharge Requirements. The results of any monitoring done more frequently than required at the locations specified in the Monitoring and Reporting Program shall be reported to the Regional Board. The results of all monitoring done shall report: 1. a concentration, if the result is above the analytical quantitation limit, 2. "trace", if the result is below the analytical quantitation limit but above the detection limit, 3. "ND", if the result is below the detection limit, and 4. a discussion regarding all peaks displayed,whether a fuel petroleum fuel component or not. (Nate: The detection limit is the minimum concentration of a substance that can be measured and reported with 99 percent confidence that the true value is greater than zero. The quantitation limit is the lowest level that can be reliably achieved within the specific limits of precision and accuracy during routine laboratory operating conditions.) The Discharger shall implement the above monitoring program immediately upon the 'I
