(A) Any user subject to a 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 City during the months of June and December, unless required more frequently in the pretreatment standard or by the City, 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 exceed the average daily flow. At the discretion of the Mayor and in consideration of such factors as local high or low flow rates, holidays, budget cycles, etc., the Mayor may agree to alter the months during which the above reports are to be submitted.
(B) The City may impose mass limitation on users where the imposition of mass limitations are appropriate. In such cases, the report required by § 50.068(A) shall indicate the mass of pollutants regulated by pretreatment standards in the effluent of the user.
(C) The reports required by this subchapter 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 Mayor, of pollutants contained therein which are limited by the applicable pretreatment standards. The frequency of monitoring shall be prescribed in the wastewater discharge permit or the pretreatment standard. All analyses shall be performed in accordance with procedures established by the Administrator pursuant to Section 304 (g) of the Act and contained in 40 CFR, Part 136, and amendments thereto or with any other test procedures approved by the Mayor. Sampling shall be performed in accordance with the techniques approved by the Superintendent.
