(1) Pollutant concentration levels snail not exceed the storm water discharge limits or be outside the ranges indicated in the table. Actual or measured levels which exceed those storm water discharge limits or are outside those ranges shall be reported to the director as required in section 10(c) of this general permit.
(2) The permittee shall collect samples for analysis from a discharge resulting from a representative storm. A representative storm means a rainfall that accumulates more than 0.1 inch of rain and occurs at least seventy-two hours after the previous measurable (greater than 0.1 inch) rainfall event.
"Grab sample" means a sample collected during the first fifteen minutes of the discharge.
"Composite sample" means a combination of at least two sample aliquots, collected at periodic intervals. The composite shall be flow proportional; either the time interval between each aliquot or the volume of each aliquot must be proportional to the total flow of storm water discharge flow since the collection of the previous aliquot. The permittee may collect aliquots manually or automatically, unless otherwise stated.
Samples for analysis shall be collected during the first fifteen minutes of the discharge and at fifteen-minute intervals thereafter for the duration of the discharge, as applicable, if the discharge lasts for over an hour, sample collection may cease.
(3) The value shall not exceed the applicable not to exceed the given value more than ten per cent of the time wet or dry season limit as specified in chapter 11-54 for the applicable classification of the receiving state waters. If no limitation is specified in chapter 11-54, then the permittee shall monitor and report the analytical result. The department may include discharge limitations specified in section 11-55-19 and discharge limitations based on Federal Register, Vol. 73, No. 189, pages 56572-56578, dated September 29, 2008.
(4) if the duration of the discharge event is less than thirty minutes, the sample collected during the first fifteen minutes of the discharge shall be analyzed as a grab sample and reported toward the fulfillment of this composite sample specification. If the duration of the discharge event is greater than thirty minutes, the Permittee shall analyze two or more sample aliquots as a composite sample.
(5) The total nitrogen parameter is a measure of all nitrogen compounds in the sample (nitrate, nitrite, ammonia, dissolved organic nitrogen, and organic matter present as particulates).
(6) Oil and Grease shall be measured by EPA Method 1664, Revision A.
(7) The pH value shall not be outside the range as specified in chapter 11-54 for the applicable classification of the receiving state waters.
(8) The pH shall be measured within fifteen minutes of obtaining the grab sample.
(9) The permittee shall measure for toxic pollutants, as identified in Appendix D of 40 CFR Part 122; in the Federal Register, Vol. 73, No. 189, pages 56572-56578, dated September 29, 2008; or in section 11-54-4. The permittee shall measure for the total recoverable portion of all metals. If monitoring results indicate that the discharge limitation was equaled or exceeded, the storm water pollution control plan shall be amended to include additional best management practices targeted to reduce the parameter which was in excess of the discharge limitation.
(10) Storm water discharge limitations are the acute water quality standards established in section 11-54-4, for either fresh or saline waters. For pollutants which do not have established acute water quality standards, the permittee shall report any detected concentration greater than 0.01 µg/1.
(11) The permittee shall measure for cyanide and the volatile fraction of the toxic organic compounds using a grab sample. The permittee shall measure for all other pollutants, as identified in Appendix D of 40 CFR Part 122; in Federal Register, Vol. 73, No. 189, pages 56572-56578, dated September 29, 2008; or in section 11-54-4 using a composite sample.
