(A) Any user 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 POTW, shall submit to the POTW during the months of June and December, unless required more frequently by the POTW, 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. Flows shall be reported on the basis of actual measurement; however, where cost or feasibility considerations justify, the POTW may accept reports of average and maximum flows estimated by verifiable techniques. The POTW for good cause when considering such factors as local high or low flow rates, holiday, budget cycles, or other extenuating factors, may authorize the submission of said reports on months other than those specified above.
(B) The POTW may impose miss limitations on users which are using dilution to meet applicable pretreatment standards or requirements, or in other cases where the imposition of mass limitations are appropriate. In such cases, the report required by division (A) of this section shall indicate the mass of pollutants regulated by pretreatment standards in the effluent of the user.
(C) These reports 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 Superintendent, of pollutants contained therein which are limited by the applicable pretreatment standards.
(D) For industrial users subject to equivalent mass or concentration limits established by the POTW in accordance with the procedures in 40 CFR 403.6(c), the report required by paragraph (e)(1) shall contain a reasonable measure of the user's long- term production rate. For all other industrial users subject to categorical pretreatment standards expressed only in terms of allowable pollutant discharge per unit of production (or other measure of operation), the report required by paragraph (e)(1) shall include the user's actual average production rate for the reporting period.
(E) Reports of significant industrial users shall contain all results of sampling and analysis of the discharge, including the flow and the nature and concentration, or production and mass where required by the POTW. The frequency of monitoring by the discharger shall be as deemed necessary by the POTW to assess and assure compliance by the industrial user with applicable pretreatment standards and requirements.
