ATTACHMENT B <br />-2- <br />MONITORING AND REPORTING PROGRAM <br />GENERAL ORDER FOR DISCHARGE OF <br />GROUND WATER FROM CLEANUP OF <br />PETROLEUM FUEL POLLUTION <br />TO SURFACE WATERS <br />detectable TPH, Benzene, Ethylbenzene, Toluene, or Xylene, the Discharger <br />shall immediately resample and reanalyze the effluent for the detected <br />constituent(s), and shall continue sampling the effluent on a weekly basis <br />until the constituent(s) concentrations are below detection. <br />* * * Test species shall be either Fathead minnows - Pimephales promelas or Golden <br />shiner - Notemiunus crvsoleucas. <br />RECEIVING WATER MONITORING <br />All receiving water samples shall be grab samples. Receiving water samples shall <br />be taken from the following: <br />Station <br />R-1 <br />R-2 <br /> <br />Description <br /> <br />upstream from the point of discharge at a location approved by <br />staff. <br />downstream from the point of discharge at a location approved <br />by staff. <br />Sampling <br />Constituents Units Station Frequency <br />pH pH Units R-1, R-2 Monthly <br />Temperature °F R-1, R-2 Monthly <br />Specific Conductivity Anhos/cm R-1, R-2 Monthly <br />In conducting the receiving water sampling, a log shall be kept of the receiving <br />water conditions throughout the reach bounded by Stations R-1 and R-2. Attention <br />shall be given to the presence or absence of: <br />a. Floating or suspended matter b. Discoloration <br />c. Bottom deposits d. Aquatic life <br />Notes on receiving water conditions shall be summarized in the monitoring report. <br />REPORTING <br />In reporting the monitoring data, the Discharger shall arrange the data in <br />tabular form so that the date, the constituents, and the concentrations are
