(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 §§ 50.041 and 50.048 within the time limitations specified by EPA, the state, or the Utility Director, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user's expense.
(B) For existing users, the Utility Director may at any time require a user to install, operate and maintain a pretreatment system based on the pollutants discharged by the user.
(C) If any waters or wastes are discharged, or are proposed to be discharged to the Wastewater Facilities, that contain the substances or possess the characteristics enumerated in §§ 50.041 and 50.048, and which in the judgment of the Utility Director may have a deleterious effect upon the wastewater facilities, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Utility Director may:
(1) Reject the wastes;
(2) Require pretreatment to an acceptable condition for discharge to the public sewers;
(3) Require control over the quantities and rates of discharge; and
(D) Detailed plans describing such facilities and operating procedures shall be submitted to the Utility Director for review. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the utility under the provisions of this chapter.
(E) The Utility Director may require a user of sewer services to provide information needed to determine compliance with this chapter. These requirements may include:
(1) Wastewaters discharge peak rate and volume over a specified period.
(2) Chemical analyses of wastewaters.
(3) Information on raw materials, processes and products affecting wastewater volume and quality.
(4) Quantity and disposition of specific liquid, sludge, oil, solvent or other materials important to sewer use control.
(5) A plot plan of sewers of the user's property showing sewer and pretreatment facility location.
(6) Details of wastewater pretreatment facilities.
(7) Details of systems to prevent and control the losses of materials through spills to the municipal sewer.
(F) When considering the above alternatives in (C), the Utility Director shall consider the economic impact of each alternative on the discharger. If the Utility Director permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Utility Director.
(G) Where pretreatment or flow-equalizing facilities are provided or required for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense.
(H) When required by the Utility Director, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable structure together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling, and measurement of the wastes. Such structure, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Utility Director. The structure shall be installed by the owner at his expense and shall be maintained in a safe and accessible manner at all times by the owner.
(I) The piping/plumbing for new buildings constructed for use by industrial users shall segregate domestic and industrial wastewater discharges. This will apply to construction of new buildings, or additions to buildings after the adoption of this chapter.
(J) All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this section shall be determined in accordance with the latest edition of Standard Methods for sampling methods, location, times, durations and frequencies are to be determined on an individual basis subject to approval by the Utility Director.
(K) No statement contained in this article shall be construed as preventing any special agreement or arrangement between the City and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the City for treatment.
