Sec. 15.
(a) Permittees shall report to the commissioner, using discharge monitoring reports (DMR) (EPA Form 3320-1) and, also, in the case of POTWs, semipublic, state, and federal facilities' reports of operation, the results of any monitoring specified by the permit, under section 13 of this rule, as often as required by the permit, but in no case less than once per year. POTWs with pretreatment or hybrid pretreatment requirements in their NPDES permits as well as industrial dischargers shall also submit the results of effluent analysis on the Indiana Monthly Monitoring Report (MMR) for Industrial Discharge Permits (State Form 30530). Alternatively, permittees may be required by the commissioner to utilize agency-approved electronic reporting formats for the submittal of all NPDES-related reports in lieu of submitting paper copies of such documents.(b) If the permittee monitors any pollutant more frequently than required by the permit, using approved analytical methods, the results of this monitoring shall be reported in the DMR. Other monitoring data not specifically required in the permit (such as internal process or internal wastestream data) that is collected by or for the permittee need not be submitted unless requested by the commissioner. Any such additional monitoring data that indicates a violation of a permit limitation shall be followed up by the permittee, whenever feasible, with a monitoring sample obtained and analyzed pursuant to approved analytical methods. The results of the analysis of the follow-up sample shall be reported to the commissioner in the permittee's DMR.(c) All reports required by this section shall be prepared by or under the direction of a certified wastewater treatment plant operator or a certified water treatment plant operator licensed under the provisions of 327 IAC 5-22 or 327 IAC 8 when such reports concern a discharge originating in whole or in part from a wastewater treatment plant or a water treatment plant, respectively, as defined in IC 13-11-2.(d) As used in this section, "approved analytical methods" means those test procedures for the analysis of pollutants under section 13(d) of this rule.(e) NPDES effluent data is to be reported on the monthly DMRs as follows: (1) Effluent concentrations less than the LOD shall be reported as less than the value of the LOD. For example, if a substance is not detected at a concentration of one (1.0) milligram per liter, the value shall be reported as[LESS THAN]1.0 mg/l.(2) Effluent concentrations greater than or equal to the LOD shall be reported at the measured value. Effluent concentrations greater than or equal to the LOD and less than the LOQ that are reported on a DMR shall be annotated on the DMR to indicate that the value is not quantifiable.(3) Except as provided in section 11.6(h)(3) of this rule, when the individual daily values are averaged for the purpose of determining the weekly average or monthly average, values less than the LOQ shall be accommodated in calculation of the averages using statistical methods that have been approved by the commissioner.(4) Mass discharge values that are calculated from concentrations reported as less than the value of the LOD shall be reported as less than the corresponding mass discharge value.(5) Mass discharge values that are calculated from effluent concentrations greater than the LOD shall be reported at the calculated value.(6) Except as provided in section 11.6(h)(3) of this rule, when the individual daily mass discharge values are averaged for the purpose of determining the weekly average or monthly average, values less than the LOQ shall be accommodated in calculation of the averages using statistical methods that have been approved by the commissioner.Water Pollution Control Board; 327 IAC 5-2-15; filed Sep 24, 1987, 3:00 p.m.: 11 IR 629; filed Feb 26, 1993, 5:00 p.m.: 16 IR 1754; filed Jan 14, 1997, 12:00 p.m.: 20 IR 1466; filed Feb 14, 2005, 10:05 a.m.: 28 IR 2126Filed 10/9/2015, 4:07 p.m.: 20151104-IR-327100659FRA
