(a) Any industrial user either: (1) subject to a pretreatment standard; or (2) considered to be a significant industrial user, 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 substance in the effluent which are required by the wastewater discharge permit. In cases where the Pretreatment Standard requires compliance with a Best Management Practice (BMP) or pollution prevention alternative, the user must submit documentation required by the Director or the Pretreatment Standard necessary to determine the compliance status of the user. 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 of feasibility conditions justify, the Director may accept reports of average and maximum flows estimated by verifiable techniques. The Director, 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. Where required by the wastewater discharge permit the report shall include production and operating data.
(b) All wastewater samples must be representative of the user's discharge. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of a user to keep its monitoring facility in good working order shall not be grounds for the user to claim that sample results are unrepresentative of its discharge.
(c) If a user subject to the reporting requirement in this section monitors any regulated pollutant at the appropriate sampling location more frequently than required by the Director, using the procedures prescribed in Section 905.306 of these regulations, the results of this monitoring shall be included in the report. (Ord. 30-14. Passed 3-3-14.)
