(A) Compliance date report. Within 90 days following the date for final compliance by the discharger with applicable pretreatment standards set forth in this chapter or 90 days following commencement of the introduction of wastewater into the POTW by a new discharger, any discharger subject to this chapter shall submit to the authority a report indicating the nature and concentration of all prohibited or regulated substances contained in its discharge, and the average and maximum daily flow in gallons. The report shall state whether the applicable pretreatment standards or requirements are being met on a consistent basis and, if not, what additional O & M or pretreatment is necessary to bring the discharger into compliance with the applicable pretreatment standards or requirements. This statement shall be signed by an authorized representative of the discharger and certified to by a qualified engineer licensed to practice in the state.
(B) Periodic compliance reports.
(1) Any discharger subject to a pretreatment standard set forth in this chapter, after the compliance date of such pretreatment standard, or, in the case of a new discharger, after commencement of the discharge to the authority, shall submit to the authority during the months of June and December, unless required more frequently by the authority, a report indicating the nature and concentration of prohibited or regulated substances in the effluent, which are limited by the pretreatment standards hereof. In addition, this report shall include a record of all measured or estimated average and maximum daily flows during the reporting period reported in division (A) above. Flows shall be reported on the basis of actual measurement, provided however, where cost or feasibility considerations justify, the authority may accept reports of average and maximum flows estimated by verifiable techniques. The authority, for good cause shown considering such factors as local high or low flow rates, holidays, budget cycles, or other extenuating factors, may authorize the submission of said reports on months other than those specified above.
(2) Reports of discharges shall contain all results of sampling and analysis of the discharge, including the flow and nature and concentration or production and mass where required by the authority. The frequency of monitoring by the discharger shall be as prescribed in the applicable pretreatment standard of this chapter. All analyses shall be performed in accordance with 40 CFR, Part 136 and amendments thereto.
(3) Where 40 CFR, Part 136 does not include a sampling or analytical technique for the pollutant in question, sampling and analysis shall be performed in accordance with the procedures set forth in the EPA publication, "Sampling and Analysis Procedures for Screening of Industrial Effluent for Priority Pollutants", April, 1977 and amendments thereto, or with any other sampling and analytical procedures approved by the Administrator of the U.S. EPA.
