All <br />samples shall be taken at the monitoring points specified in this permit and, unless otherwise specified, before the effluent joins or is <br />diluted by any other wastestream, body of water, or substance. Monitoring points shall not be changed without notification to and <br />approval by the Division. <br />If the permittee monitors at the point of discharge any pollutant limited by the permit more frequently than required by the permit, using <br />approved test procedures or as specified in the permit, the result of this monitoring shall be included in the calculation and reporting of <br />data to the Division. <br />4.

When requested in writing, the Division may approve an alternative analytical procedure or and <br />significant modification to an approved procedure. <br />When the most sensitive analytical method which complies with this part, has a detection limit greater than or equal to the permit limit <br />the permittee shall report less than (the detectable limit)," as appropriate. Such reports shall not be considered as violations of the permi <br />limit. The present lowest practical quantitation limits (PQL) for specific parameters (which have limitations that are, in some cases, les: <br />than or equal to the detection limit) are as follows: <br />Effluent Parameter PQLs, µg/1 <br />Arsenic I <br />Cadmium 0.06 <br />Chromium 2 <br />Chromium, 2 <br />Hexavalent <br />Copper 5 <br />Cyanide 10 <br />Iron 10 <br />Lead 1 <br />Manganese 2 <br />Mercury 0.003 <br />Nickel 3 <br />Phenols 15 <br />Selenium 1 <br />Silver 0.5 <br />Uranium 1 <br />Zinc 10 <br />These limits apply to the total recoverable or the potentially dissolved fraction of metals.
