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.
