(A) Users shall provide wastewater treatment as necessary to comply with this chapter and shall achieve compliance with all categorical pretreatment standards, local limits and the prohibitions set out in § 52.020 within the time limitations specified by EPA, the state or the city, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated and maintained at the user’s expense. Detailed plans describing the facilities and operating procedures shall be submitted to the Authority for review, and shall be acceptable to the Authority before the facilities are constructed. The review of the plans and operating procedures shall in no way relieve the user from the responsibility of modifying the facilities as necessary to produce a discharge acceptable to the city under the provisions of this chapter.
(‘89 Code, § 105.13)
(B) (1) Whenever deemed necessary, the Authority may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and remedy any other conditions as may be necessary to protect the POTW and determine the user’s compliance with the requirements of this chapter.
(2) The Authority may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
(3) Grease, oil and sand interceptors shall be provided when, in the opinion of the Authority, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil, or sand. All interception units shall be of type and capacity approved by the Authority, and shall be so located to be easily accessible for cleaning and inspection. The interceptors shall be inspected, cleaned, and repaired as needed, according to design specifications of the interceptor by and at the user’s expense. Interceptor maintenance shall be properly documented and records of the same shall be retained for review.
(4) Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.

(C) At least once every two years, the Authority shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan. The Authority may require any user to develop, submit for approval, and implement this type of plan. An accidental discharge/slug control plan shall address, at a minimum, the following elements found at 40 CFR Part 403.8(f)(2)(v)(A)-(D):
(1) Description of discharge practices, including non-routine batch discharges;
(2) Description of stored chemicals;
(3) Procedures for immediately notifying the Authority of any accidental or slug discharge, as required by § 52.065; and
(4) Procedures to prevent adverse impact from any accidental or slug discharge. These procedures include, but are not limited to inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response.
(D) (1) Septic tank waste may be introduced into the POTW only at locations designated by the Superintendent, and at times as are established by the Superintendent. The waste shall not violate §§ 52.20 through 52.24 or any other requirements established by the city. The Authority may require septic tank waste haulers to obtain wastewater discharge permits.
(2) The Authority shall require haulers of industrial waste to obtain industrial wastewater discharge permits. The Authority shall require generators of hauled industrial waste to obtain wastewater discharge permits. The Authority also may prohibit the disposal of hauled industrial waste. The discharge of hauled industrial waste is subject to all requirements of this chapter.
(3) Industrial waste haulers may discharge loads only at locations designated by the Authority. No load may be discharged without prior consent of the Authority. The Authority may collect samples of each hauled load to ensure compliance with applicable standards. The Authority may require the industrial waste hauler to provide a waste analysis of any load prior to discharge.
(4) Industrial waste haulers must provide a waste-tracking form for every load. This form shall include, at a minimum, the name and address of the industrial waste hauler, permit number, truck identification, names and addresses of sources of waste, and volume and characteristics of waste. The form shall identify the type of industry, known or suspected waste constituents, and whether any wastes are RCRA hazardous wastes.
