(A) Any user subject to a categorical pretreatment standard, after the compliance date of such pretreatment standard, or, in the case of a new source, after commencement of the discharge into the POTW, shall submit to the POTW during the months of June and December, unless required more frequently in the pretreatment standard or by the Superintendent, a report indicating the nature and concentration, of pollutants in the effluent which are limited by such pretreatment standards. In addition, this report shall include a record of all daily flows which during the reporting period exceeded the average daily flow reported in § 51.105(D)(4)(b). At the discretion of the Superintendent and in consideration of such factors as local high or low flow rates, holidays, budget cycles, etc., the Superintendent may agree to alter the months during which the above reports are to be submitted.
(B) The POTW may impose mass 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. 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.
(C) 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 division (A) of this section 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 division (A) above shall include the user's actual average production rate for the reporting period.
(D) Significant noncategorical industrial users shall submit to the POTW at least once every six months (on dates specified by the local agency) a description of the nature, concentration, and flow of the pollutants required to be reported by the local agency.
