PART I <br />Page 24 of 48 <br />Permit No.: C00038342 <br />If all individual analytical results are less than the PQL, the permittee shall report either "BDL" or "<X" <br />(where X = the actual PQL achieved by the laboratory), following the guidance above. <br />If one or more individual results is greater than the PQL, an average shall be calculated and reported. <br />Note that it does not matter if the final calculated average is greater or less than the PQL, it must be <br />reported as a value. <br />PQLs <br />The PQLs for specific parameters, as determined by the State Laboratory (November 2008) are provided below <br />for reference. If the analytical method cannot achieve a PQL that is less than or equal to the permit limit, <br />then the method, or a more precise method, must achieve a PQL that is less than or equal to the PQL in the <br />table below. A listing of the PQLs for further organic parameters that must meet the above requirement can <br />be found in the Division's Practical Quantitation Limitation Guidance Document, July 2008. This document is <br />available on the Division's website at www.coloradowaterpermits.com. <br />These limits apply to the total recoverable or the potentially dissolved fraction of metals. <br />For hexavalent chromium, samples must be unacidified so dissolved concentrations will be measured rather <br />than potentially dissolved concentrations. <br />Effluent <br />Parameter <br />Practical <br />Quantitation <br />Limits <br />Effluent <br />Parameter <br />Practical <br />Quantitation <br />Limits <br />Aluminum <br />50 pg/l <br />Arsenic <br />1 pg/l <br />N -Ammonia <br />1 mg/1 <br />Barium <br />5 pg/1 <br />N -Ammonia (low-level) <br />50 pg/1 <br />Beryllium <br />1 pg/t <br />N- Nitrate/ Nitrite <br />0.5 mg/l <br />BOD / CBOD <br />1 mg/l <br />N -Nitrate <br />0.5 mg/l <br />Boron <br />50 pg/l <br />N -Nitrite <br />10 pg/l <br />Cadmium <br />1 pg/l <br />Total Nitrogen <br />0.5 mg/1 <br />Calcium <br />20 pg/l <br />Total Phosphorus <br />10 pg/l <br />Chloride <br />2 mg/1 <br />Chlorine <br />0.1 mg/l <br />Radium 226 <br />1 pCi/l <br />Total Residual Chlorine <br />Radium 228 <br />1 pCi/l <br />DPD colorimetric <br />0.10 mg/l <br />Selenium <br />1 pg/l <br />Amperometric titration <br />0.05 mg/1 <br />Silver <br />0.5 pg/l <br />Chromium <br />20 pg/l <br />Sodium <br />0.2 mg/1 <br />Chromium, Hexavalent <br />20 pg/l <br />Sulfate <br />5 mg/l <br />Copper <br />5 pg/l <br />Sulfide <br />0.2 mg/1 <br />Cyanide (Direct / <br />Distilled) <br />10 pg/l <br />Total Dissolved Solids <br />10 mg/t <br />Cyanide, WAD+A47 <br />10 pg/l <br />Total Suspended Solids <br />10 mg/1 <br />Fluoride <br />0.1 mg/l <br />Thallium <br />1 pg/l <br />Iron <br />10 pg/l <br />Uranium <br />1 pg/t <br />Lead <br />1 pg/l <br />Zinc <br />10 pg/l <br />Magnesium <br />20 pg/l <br />Manganese <br />2 pg/l <br />Phenols <br />15 pg/l <br />Mercury <br />0.1 pg/l <br />Nonylphenol D7065 <br />10 pg/t <br />Mercury (low-level) <br />0.003 pg/l <br />Nonylphenol D7485 <br />0.33 pg/t <br />Nickel <br />50 pg/l <br />3.
