Reporting deadlines for industrial wastewater pretreatment compliance

(a) Compliance schedule progress report. The conditions herein shall apply to any compliance schedule required by the director. The schedule shall set forth progress increments in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the industrial user to meet the applicable pretreatment standards (such events include hiring an engineer, completing preliminary and final plans, executing contracts for major components, commencing and completing construction, and beginning and conducting routine operations). No increment set forth herein shall exceed nine months. The industrial user shall submit a progress report to the director no later than 14 days following each date in the schedule and the final date of compliance including, as a minimum, whether or not it complied with steps being taken by the industrial user to return to the established schedule. In no event shall more than nine months elapse between such progress reports to the director. (b) Report on compliance with categorical pretreatment standard deadline. Within 90 days following the date for final compliance with applicable categorical pretreatment standards, or in the case of a new source, following commencement of the introduction of wastewater into the POTW, any industrial user subject to such pretreatment standards and requirements shall submit to the director a report containing the measurement of flow and pollutant and certification of pretreatment standards being consistently met. If pretreatment standards are not being met consistently, a description of additional operation and maintenance requirements or pretreatment shall be included in the report. For industrial users subject to equivalent mass or concentration limits established in accordance with the procedures in 40 CFR § 403.6(c), this report shall contain a reasonable measure of the industrial user’s long-term production rate. For all other industrial users subject to categorical pretreatment standards in terms of allowable pollutant discharge per unit of production (or other measure of operation), this report shall include the industrial user’s actual production during the appropriate sampling period. All compliance reports shall be signed and certified in accordance with § 43-5.11 (c). (c) Periodic compliance reports. (1) Any significant industrial user subject to a pretreatment standard shall, at a frequency determined by the director, but in no case less than twice a year (in June and December), submit a report indicating the nature and concentration of pollutants in the discharge, which are limited by such pretreatment standards, and the measured or estimated average and maximum daily flows for the reporting period. All periodic compliance reports shall be signed and certified in accordance with § 43-5.11 (c). (2) All wastewater samples shall be representative of the industrial user’s daily operations and discharge as described in the permit issued to the user. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure to keep the monitoring facility in good working order shall not be grounds for the user to claim that sample results do not properly report the discharge constituents and characteristics. (3) If an industrial user subject to the reporting requirements of this section monitors any pollutant more frequently than required by the POTW, using the procedures prescribed in § 43-5.11 , the results of this monitoring shall be included in the report.
