(A) 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 by the tenth day of the months following monitoring months, which shall be 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 flow rates, holidays, budget cycles or other extenuating factors may authorize the submission of said reports on months other than those specified above. Reports from dischargers must be signed by an authorized representative of the discharger. All sampling results obtained by the discharger shall be reported to the Director including any sampling performed more frequently than required. Dischargers shall notify the Director in writing within 24 hours if any sampling results violate applicable pretreatment limits. Discharger shall repeat the sampling and analysis for those parameters in violation and resubmit the results within 30 days of becoming aware of the violation.
(B) Reports of dischargers 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 city. The frequency of monitoring by the discharger shall be as prescribed in the applicable pretreatment standard of this chapter. All analyses shall be performed in accordance with 40 CFR, Part 136 and amendments thereto. Where 40 CFR, Part 136 does not include a sampling or analytical technique for the pollutant in question, sampling and analysis shall be performed in accordance with the procedures set forth in the EPA publication, "Sampling and Analysis Procedures for Screening of Industrial Effluents for Priority Pollutants", April, 1977, and amendments thereto, or with any other sampling and analytical procedures approved by the Administrator of the U.S. EPA.
