(a) Baseline Monitoring Reports. Any discharger subject to a categorical pretreatment standard, upon promulgation of a categorical standard applicable to the category, shall submit to the Director a baseline monitoring report, within 180 days after the effective date of the applicable categorical standard, or within 180 days after a final decision on a category determination request, whichever is later. In the case of a new source discharger, and existing sources that become industrial users subsequent to the promulgation of an applicable categorical standard, the discharger is required to submit a baseline monitoring report at least ninety days prior to commencement of discharge. The report shall contain information identifying the discharger, a list of any environmental permits held by the discharger, a brief description of the discharger's operations, information on the nature and concentration of regulated process pollutants in the discharge, the average and maximum daily flow indicating whether the discharger is in compliance with applicable pretreatment standards, and, if not, what steps are necessary to bring the discharger into compliance. This report shall meet the signatory requirements of 40 CFR 403.12(1).
(b) Ninety-Day Compliance Report. Within ninety days following the date for final compliance with applicable pretreatment standards by the discharger or, in the case of a new industrial discharger, immediately following commencement of the introduction of wastewater into the POTW, any discharger subject to pretreatment standards and requirements shall submit to the Director 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 and M and/or pretreatment is necessary to bring the discharger into compliance with the applicable pretreatment standards or requirements. If a discharger is subject to equivalent categorical limits the report shall include the actual production during the sampling period. If a discharger is subject to equivalent mass or concentration limits, the reports shall include a reasonable measure of the discharger's long-term production rate. This report shall meet the signatory requirements of 40 CFR 403.12(l).
(c) Periodic Compliance Reports. 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 City, shall submit to the Director during the months of June and December, unless required more frequently by the Director, 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. Flows shall be reported on the basis of actual measurement, provided however, where cost or feasibility considerations justify, the Director may accept reports of average and maximum flows estimated by verifiable techniques. The City for good cause shown considering such factors as local high or low rates, holidays, budget cycles or other extenuating factors may authorize the submission of such reports on months other than those specified above. This report shall meet the signatory requirements of 40 CFR 403.12(l).
(d) Reporting of Noncategorical Discharges. Major significant industrial dischargers shall submit to the City at least once every six months, appropriate self-monitoring reports from dischargers concerning the discharge of pollutants that are not covered under categorical pretreatment standards. The subject of what is appropriate is to be made on a case-by-case basis by the City, based on such factors as the size of the discharger, the volume of the discharger's flow relative to the POTW's total flow, and the pollutants of concern being discharged. This report shall meet the signatory requirements of 40 CFR 403.12(1).
(e) Monitoring and Analysis to Demonstrate Continued Compliance.
(1) The reports required by subsections (a) to (d) hereof shall contain the results of sampling and analysis of the discharge, including the flow and the nature and concentration or production and mass where requested by the City, of pollutants contained therein which are limited by the applicable pretreatment standards;
(2) If sampling performed by a discharger indicates a violation, the discharger shall notify the City within twenty-four hours of becoming aware of the violation. The discharger shall also repeat the sampling and analysis and submit the results of the repeat analysis to the City within thirty days after becoming aware of the violation, except the discharger is not required to resample if:
A. The City performs sampling at the discharger at a frequency of at least once per month, or
B. The City performs sampling at the discharger between the time when the discharger performs its initial sampling and the time when the discharger receives the results of this sampling;
(3) The reports required by subsections (a) to (d) hereof shall be based upon data obtained through appropriate sampling and analysis performed during the period covered by the report, which data is representative of conditions occurring during the reporting period;
(4) All analysis shall be performed in accordance with procedures established in Section 304(h) of the Act and contained in 40 CFR Part 136 and any amendments thereto or with any other test procedures approved by the U.S.EPA;
(5) If a discharger subject to the reporting requirements in subsections (a) to (d) hereof monitors any pollutant more frequently than required by the City, using the procedures prescribed in subsection (e)(4) hereof the results of this monitoring shall be included in the report.
