For each priority <br /> pollutant use an analytical method from the SIP,Appendix 4 with a Minimum Level(ML)below all applicable pollutant <br /> criteria. In accordance with Section 2.4.2 of the SIP,the Discharger is to instruct the laboratory analyzing samples for <br /> priority pollutants to establish calibration standards so that the ML is the lowest calibration standard. At no time is the <br /> Discharger to use analytical data derived from extrapolation beyond the lowest point of the calibration curve.Report all <br /> peaks identified by the EPA test methods.' <br /> 3 Concurrent with metals monitoring. <br /> Use clean sample collection techniques and EPA Test Method 1669 or 1631,or later amendment for Mercury. <br /> 5 Use EPA Test Method 7742, or later amendment for Selenium <br /> 6 Dissolved Arsenic,Barium,Cyanide, Iron,Manganese, Silver,Zinc. <br /> 7 <br /> Total Nitrate (as N). <br />
