(a) Compliance Data Report. Within ninety days following the date for final compliance by a discharger with applicable pretreatment standards set forth in this chapter, or ninety 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 City 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. For dischargers subject to equivalent mass or concentration limits established by the Superintendent, the report shall include the production data requested by the Superintendent pursuant to Section 1050.07(c) of this chapter. The report shall state whether or not the applicable pretreatment standards or requirements are being met on a consistent basis and, if not, what additional operation and maintenance and/or pretreatment is necessary to bring the discharger into compliance with the applicable pretreatment standards or requirements.
(b) Periodic Compliance Reports. Any discharger subject to a national categorical pretreatment standard set forth in this chapter, after the compliance date of such national categorical pretreatment standard, or, in the case of a new discharger, after commencement of the discharge to the City, shall submit to the City, during the months of June and December, unless required more frequently by the City, a report indicating the nature and concentration of prohibited or regulated substances in the effluent which are limited by the pretreatment standards of this chapter. 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 that, where cost or feasibility considerations justify, the City 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 flow rates, holidays, budget cycles or other extenuating factors, may require the submission of such reports on months other than those specified in this paragraph. For dischargers subject to equivalent mass or concentration limits established by the Superintendent, the report shall include the production data requested by the Superintendent pursuant to Section 1050.07(c) of this chapter.
(c) Monitoring and Analysis to Determine Compliance.
(1) Reports of dischargers shall contain all results of sampling and analysis of the discharge, including the flow and the nature and concentration, or the production and mass where required by the City. Reports required in subsection (b) hereof shall be based on data obtained during the period covered by the report and on an amount of sampling appropriate for that discharger. The frequency of monitoring by the discharger shall be as prescribed in the applicable national categorical pretreatment standards or at intervals determined to be necessary by the City. If pollutant concentration in the discharge is of a varying nature, or if the likelihood of a slug of a pollutant is so great that a grab sample of the wastewater cannot be relied upon to furnish a representative analysis of the industry's discharge, then the City may require the installation of special sampling devices. These may include a continuous sampling pump coupled to a flow meter in such a way that the size of the sample is proportional to the total flow. The discharger shall be responsible for the collection and testing of the samples; however, the sampling and analysis may be performed by the Superintendent in lieu of the discharger. All tests shall be done by independent laboratories, with a copy of the results forwarded directly to the Mayor. Samples shall be collected in such a manner as is permissible under 40 C.F.R. Part 136, as amended. Laboratory procedures used in the examination of industrial waste shall be those set forth in 40 C.F.R. Part 136, as amended.
(2) If sampling performed by the discharger indicates a violation, the discharger must notify the Superintendent within twenty-four hours of becoming aware of such violation. The discharger must also repeat the sampling and submit the results of such repeated sampling to the Superintendent within thirty days of becoming aware of the violation. However, resampling by the discharger is not required if the Superintendent monitors the discharger at least once a month or if the Superintendent performs sampling between the time when the discharger performs its initial sampling and when the discharger receives the results of this sampling.
(3) If the discharger monitors more frequently than required by the Superintendent, the results from the additional monitoring shall be included in the report, but only if such results are obtained through the use of test procedures approved in 40 C.F.R. Part 136, as amended.
(d) Noncategorical Discharges. The Superintendent shall require appropriate reporting from those dischargers with discharges that are not subject to national categorical pretreatment standards.
(e) Notification of Changed Discharge. All dischargers shall promptly notify the City in advance of any substantial change in the volume or character of their wastewater.
(f) Signatory Requirements for Industrial User Reports. The reports required under this chapter shall include the certification statement as set forth in 40 C.F.R. 403.6(a)(2)(ii) and shall be signed as follows:
(1) By a responsible corporate officer (as defined in 40 C.F.R. 403.12(l)(1)) if the discharger is a corporation, or by a general partner or proprietor if the discharger is a partnership or sole proprietorship respectively.
(2) By a duly authorized representative of the discharger described in paragraph (1) above if:
A. The authorization is made in writing by the discharger described in paragraph (1);
B. The authorization specifies either an individual or a position having responsibility for the overall operation of the facility from which the discharge originates, such as the position of plant manager, operator of a well, or well field superintendent, or a position of equivalent responsibility, or having overall responsibility for environmental matters for the company; and
C. The written authorization is submitted to the Superintendent.
(3) If an authorization under paragraph (2) above is no longer accurate because a different individual or position has responsibility for the overall operation of the facility, or overall responsibility for environmental matters for the discharger, a new authorization satisfying the requirements of paragraph (2) above must be submitted to the Superintendent prior to or together with any reports to be signed by an authorized representative.
