(a) Baseline Monitoring Report. Within 180 days after the effective date of a categorical pretreatment standard, or 180 days after the final administrative decision made upon a category determination submission under 40 CFR 403.6(a)(4), whichever is later, any discharger subject to pretreatment standards and requirements and currently discharging or scheduled to discharge to the POTW shall submit to the Director a report containing information as indicated in Section 933.11
(b)(1) through (5), inclusive and a Certification Statement as indicated in Section 933.11
(b) (9). The report shall state whether 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. The compliance schedule shall be as subsequently defined in Section 933.29
. This statement will contain the Certification Statement as indicated in Section 933.11
(b) (9) and shall be signed by an authorized representative of the discharger. At least ninety days prior to commencement of discharge, new sources, and sources that become dischargers subsequent to the promulgation of an applicable categorical standard, shall be required to submit to the Director a report containing information as indicated in Section 933.11
(b)(1) through (5), inclusive and a Certification Statement as indicated in Section 933.11
(b) (9). New sources shall also be required to include in this report information on the method of pretreatment the discharger intends to use to meet applicable pretreatment standards. New sources shall give estimates of the information requested in Section 933.11
(b) (4), (5) and (9).
A minimum of four grab samples shall be used for pH, cyanide, total phenols, oil and grease, sulfide, and volatile organics. For all other pollutants, twenty-four hour composite samples shall be obtained through flow-proportional composite sampling techniques where feasible. The Director may waive flow-proportional composite sampling for any discharger that demonstrates that flow-proportional sampling is not feasible. In such cases, samples may be obtained through time-proportional composite sampling techniques or through a minimum of four grab samples where the discharger demonstrates that this shall provide a representative sample of the effluent being discharged.
(b) Compliance Date Report. Within ninety days following the date for final compliance with applicable pretreatment standards or in the case of a new source following commencement of the introduction of wastewater into the POTW, any discharger subject to pretreatment standards and requirements shall submit to the Director a report containing information as indicated in Section 933.11
(b)(4) through (6), inclusive and a Certification Statement as indicated in Section 933.11
(b) (9). The report shall state whether 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. The compliance schedule shall be as subsequently defined in Section 933.29
. This statement will contain the Certification Statement as indicated in Section 933.11
(b) (9) and shall be signed by an authorized representative of the discharger.
For dischargers subject to equivalent mass or concentration limits established by the Director in accordance with the procedures in 40 CFR 403.6(c), this report shall contain a reasonable measure of the discharger's long term production rate. For all other dischargers subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of operation), this report shall include the discharger's actual production during the appropriate sampling period. This statement shall be signed by an authorized representative of the discharger and will contain the Certification Statement as indicated in Section 933.11
(b) (9).
(c) Periodic Compliance Reports. 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 during 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 such reports on months other than those specified above. Reports from dischargers shall be signed by an "authorized representative" and will contain the Certification Statement as indicated in Section 933.11
(b) (9).
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 twenty-four hours if any sampling results violate applicable pretreatment limits. Dischargers shall repeat the sampling and analysis for those parameters in violation and resubmit the results within thirty days of becoming aware of the violation.
Any discharger subject to the provisions of 933.05 (c) Supplementary Limitations. shall submit to the authority during the months of June and December, unless required more frequently, as report indicating compliance with the BMPs.
(d) Reporting Requirements for Dischargers Not Subject to Categorical Pretreatment Standards. The Director shall require appropriate reporting from those dischargers with discharges that are not subject to categorical pretreatment standards.
