For each priority pollutant use an analytical method from the SIP,Appendix 4 <br /> with a Minimum Level(ML)below all applicable pollutant criteria. In accordance with Section 2.4.2 of the <br /> SIP,the Discharger is to instruct the laboratory analyzing samples for priority pollutants to establish <br /> calibration standards so that the ML is the lowest calibration standard. At no time is the Discharger to use <br /> analytical data derived from extrapolation beyond the lowest point of the calibration curve. Report all peaks <br /> identified by the EPA test methods. <br /> ° Concurrent with metals monitoring. <br /> ' Use clean sample collection techniques and EPA Test Method 1669 or 1631,or later amendment for Mercury. <br /> 6 Field measurements. <br /> r Use EPA Test Method 7742,or later amendment for Selenium. <br /> 8 Dissolved Arsenic,Barium,Cyanide,Iron,Manganese, Silver,Zinc. <br /> 9 Total Nitrate(as N). <br /> In conducting the receiving water sampling, a log shall be kept of the receiving water conditions <br /> throughout the reach bounded by Stations R-1 and R-2. Attention shall be given to the presence of: <br /> a. Floating or suspended matter e. Visible films, sheens or coatings <br /> b. Discoloration f. Fungi, slimes, or objectionable growths <br /> c. Bottom deposits g. Potential nuisance conditions <br /> d. Aquatic life <br /> Notes on receiving water conditions shall be summarized in the monitoring reports. <br />
