(A) Upon notification by the Superintendent of Utilities that pretreatment of an industrial user’s wastewater discharges is required, the user shall:
(1) Submit to the Superintendent, within 14 calendar days of notification, a statement acknowledging the notification and indicating the user’s intent to proceed to provide remedial pretreatment equipment and/or procedures; and
(2) Submit to the Superintendent, as directed, a proposed compliance schedule to carry out the necessary work leading to implementation of operations/procedural changes, or installation of pretreatment facilities within the shortest time possible. The compliance schedule shall indicate the separate milestone steps to be taken, the dates for completion of each step and a final date for achieving compliance.
(B) If the original compliance schedule is not acceptable to the Superintendent, the user shall submit additional information, data or a revised schedule within 30 days of notification of the unacceptable provisions submitted. Failure to submit an acceptable compliance program shall be considered unsatisfactory progress and may result in orders to remove the unacceptable discharge from the sewerage system, or refusal to permit a proposed new discharge.
(C) Upon acceptance by the Superintendent of the pretreatment compliance program, the industrial user shall proceed to implement the program in accordance with the compliance schedule as accepted. The user shall submit periodic progress reports as required by the Superintendent, indicating whether or not the scheduled milestone dates are being achieved and, if not, what steps are being taken to return to the approved schedule for meeting the final compliance date.
(D) Failure to meet the compliance schedule milestone dates, final compliance date or reporting requirements shall be subject to enforcement pursuant to the applicable provisions of this chapter, including notice of violation, administrative fees, revocation of treatment service and penalty action.
(Prior Code, § 1054.08) (Ord. 59-1991, passed 4-8-1991; Ord. 149-2013, passed 9-9-2013)
Where installation of new or modified pretreatment facilities is required to comply with pretreatment standards and limitations, all industrial users shall submit applications for a permit to install to the Superintendent of Utilities and the Ohio EPA for approval prior to construction or installation. Applications shall include detailed plans, specifications and sufficient design information to allow proper evaluation of the proposed pretreatment facilities. Approval by the Superintendent does not, in any way, guarantee that the facilities will function satisfactorily or that it will not be necessary to enlarge or otherwise modify the facilities to make them capable of providing satisfactory pretreatment. It remains the responsibility of the user to provide a pretreatment system that will ensure consistent compliance with all discharge limitations.
(Prior Code, § 1054.09) (Ord. 59-1991, passed 4-8-1991; Ord. 149-2013, passed 9-9-2013)
Wastewater pretreatment or control facilities, as required, shall be maintained continuously in satisfactory and effective operation and shall be subject to periodic inspection by the Control Authority. The industrial user shall maintain all records of operation necessary to document performance of the pretreatment system, and shall submit reports on the characteristics of wastewater discharge as required by the Superintendent of Utilities or this chapter to demonstrate compliance with applicable pretreatment standards and requirements.
(Prior Code, § 1054.10) (Ord. 59-1991, passed 4-8-1991; Ord. 149-2013, passed 9-9-2013)
(A) National categorical pretreatment standards for new and existing indirect sources, as promulgated under 40 C.F.R. § 403.6 and 40 C.F.R. Ch. I, Subch. N, are hereby incorporated as part of this chapter by reference. Industrial users subject to the applicable categorical standards shall comply with the more stringent of these standards or the local limitations established and adopted by the city.
(B) The city shall develop limitations for pollutants of concern contributed by industrial users in concentrations that may cause interference or pass through of the POTW treatment works.
(C) Best management practices (BMPs) may be developed by the control authority as a local limit and if so, shall be incorporated in the administrative orders of wastewater acceptance.
(D) The city reserves the right to add to or revise local limitations on discharges to the POTW, as deemed necessary to ensure continued compliance with the POTW’s NPDES permit, or sludge use or disposal practices.
(E) Specific effluent limits shall not be developed and enforced without individual notice to persons or groups who have requested such notice and an opportunity to respond. Industrial users affected by the adoption of new or revised pollutant limitations shall be given a reasonable period of time to comply with such changes.
(F) No industrial user shall discharge wastewater concentrations and/or mass-based loadings to the POTW exceeding the limitations for the regulated pollutants specified in the user’s administrative orders of wastewater acceptance issued by the city, or any discharge violating the prohibited discharges listed in § 1054.04(A) and (B) of this chapter.
(G) (1) No industrial user shall discharge or cause to be discharged into the sewerage system any regulated substance or pollutant in concentrations above the background concentrations as established by the city, unless the pollutant is listed and limitations are provided in administrative orders of wastewater acceptance issued by the city.
(2) Categorical users regulated by concentration-based may now have those limits converted to equivalent mass-based limits according to 40 C.F.R. § 403.6(c)(5).
(H) Sampling and analysis of all pollutants regulated under this chapter shall be performed according to approved test methods established and contained in 40 C.F.R. part 136, and amendments thereto, or analytical methods directly specified by 40 C.F.R. part 403. Where approved test methods or procedures for a given pollutant are not included or are inappropriate, any alternative method developed must be validated and approved by the Administrator of the U.S. EPA.
(I) The authority may impose mass-based limitations on industrial users which are using dilution to meet the pretreatment standards or limitations of this chapter, or in other cases where the imposition of mass limitations is deemed appropriate.
(J) When limits in categorical pretreatment standards are expressed only in terms of mass of pollutants per unit of production, the authority may convert the mass-based limits to equivalent mass-based limitations expressed either as mass discharged per day or as effluent concentration limits. The equivalent concentration- based limitations will be deemed pretreatment standards which industrial users will be required to comply with in lieu of promulgated standards per 40 C.F.R. § 403.6(c)(6).
(K) The Authority may control, by administrative order, any industrial user discharge of conventional pollutants (BOD, COD, TSS and the like), and discharge flow rates, to limit excessive pollutant concentrations and loadings or to prevent an adverse impact on the POTW treatment plant operations.
(L) Any violation of applicable federal, state or city industrial pretreatment standards is a violation of this chapter.
(Prior Code, § 1054.11) (Ord. 59-1991, passed 4-8-1991; Ord. 149-2013, passed 9-9-2013)
Except where expressly authorized by an applicable pretreatment standard, no industrial user shall increase the use of potable or process water, or in any way attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the discharge limitations.
(Prior Code, § 1054.12) (Ord. 59-1991, passed 4-8-1991; Ord. 149-2013, passed 9-9-2013)
(A) At the discretion of the Superintendent of Utilities, any user discharging to the sewerage system shall provide, operate and maintain, at the discharger’s own expense, a monitoring facility to enable inspection, sampling, and flow measurement of each waste water discharge to the POTW. The Superintendent may require the user to install appropriate sampling and flow monitoring equipment where needed to determine compliance with applicable pretreatment standards or extra-strength surcharges.
(B) Each monitoring facility shall be located on the user’s premises, except, where such a location would be impractical; the Superintendent may concur with construction on the public sidewalk or berm. Facility locations shall be free of obstruction by equipment, parked vehicles or landscaping, and be free of moving vehicular traffic hazards. There shall be ample room in or near such sampling facility to allow accurate sampling and preparation of samples for analysis. All monitoring instrumentation required shall be periodically calibrated and maintenance procedures shall be performed to ensure accuracy of measurements. Flow measuring devices shall be calibrated at a minimum of once per year, and a written statement of calibration, giving the date performed and the name of the qualified service agent, shall be submitted to the Superintendent for each calibration performed.
(C) Plans for the monitoring facilities shall be submitted for approval to the Superintendent within 60 days of notification of the need for a facility. The installation shall be completed within 90 days of the plan approval by the Superintendent.
(D) Access to the monitoring facility shall be made available immediately to authorized representatives of the Superintendent for the purpose of inspection, or conducting independent sampling and monitoring activities.
