If the permit contains a report only requirement for a parameter, the analytical method and PQL chosen shall be one that can <br />measure at or below the benchmark, or water quality standard, or other level approved by the Division. If all analytical methods and <br />corresponding PQLs are greater than the benchmark, or water quality standard, or other level, then the analytical method with the <br />lowest PQL shall be used. <br />If the permit contains an interim effluent limitation (a limit is report until such time as a numeric effluent limit becomes effective) for <br />a parameter, the analytical method and PQL chosen for all monitoring conducted in accordance with this permit for the parameter <br />shall be one that can measure to the final numeric effluent limit. If all analytical methods and corresponding PQLs are greater than <br />the final numeric effluent limit (s), then the analytical method with the lowest PQL shall be used. <br />For parameters such as TIN, the analytical methods chosen shall be those that can measure to the potential or final numeric effluent <br />limit, based on the sum of the PQLs for nitrate, nitrite and ammonia. <br />When the analytical method which complies with the above requirements has a PQL greater than the permit limit, and the <br />permittee's analytical result is less than the PQL, the permittee shall report "BDL" on the DMR. Such reports will not be considered <br />as violations of the permit limit, as long as the lowest available PQL is used for the analysis. When the analytical method which <br />complies with the above requirements has a PQL that is equal to or less than the permit limitation, and the permittee's analytical <br />result is less than the PQL, "< X" (where X = the actual PQL achieved by the laboratory) shall be reported on the DMR. For <br />parameters that have a report only limitation, and the permittee's analytical result is less than the PQL, "< X" (where X = the actual <br />PQL achieved by the laboratory) shall be reported on the DMR. <br />In the calculation of average concentrations (i.e. 7- day average, 30 -day average, 2 -year rolling average), any individual analytical <br />result that is less than the PQL shall be considered to be zero for the calculation purposes. When reporting: <br />If all individual analytical results are less than the PQL, the permittee shall report either "BDL" or "<X" (where X = the actual PQL <br />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. Note that it does not <br />matter if the final calculated average is greater or less than the PQL, it must be reported as a value. <br />Note that when calculating T.I.N. for a single sampling event, any value less than the PQL (for total ammonia, total nitrite, or total <br />nitrate) shall be treated as zero. The T.I.N. concentration for a single sampling event shall then be determined as the sum of the <br />analytical results (zeros if applicable) of same day sampling for total ammonia and total nitrite and total nitrate. From these <br />calculated T.I.N. concentrations, the daily maximum and thirty day average concentrations shall be calculated and must be <br />reported as a value. <br />The present lowest PQLs for specific parameters, as determined by the State Laboratory (November 2008) are provided below. If <br />the analytical method cannot achieve a PQL that is less than or equal to the permit limit, then the method, or a more precise <br />method, must achieve a PQL that is less than or equal to the PQL in the Table H -1 below. A listing of the PQLs for organic <br />parameters that must meet the above requirement can be found in the Division's Practical Qliantitation Limitation Guidance <br />Document, July 2008. <br />These limits apply to the total recoverable or the potentially dissolved fraction of metals. <br />
