(a) If the Director determines that an Industrial User's wastes may be harmful to the structures, processes or operation of the POTW, the User shall provide, operate and maintain, at its own expense, such pretreatment or processing facilities as may be determined necessary to render the wastes acceptable for admission to the public sewers. Such pretreatment shall achieve compliance with this chapter and all Categorical Pretreatment Standards, Local Limits, and the prohibitions set out in Sections 930.03 and 930.04 of this chapter within the time limitations specified by USEPA, the Ohio EPA, or the Control Authority, whichever is more stringent.
(b) Any User producing a slug discharge into the public sewers or a discharge requiring flow equalization as determined by the Control Authority shall construct, operate and maintain, at the User's own expense, a suitable storage and flow-control facility to insure equalization of discharge over a twenty-four (24) hour period. This facility shall have a capacity of at least twenty percent (20%) of the total normal volume of a twenty-four (24) hour production period, and the outlet to the sewer shall be equipped with a rate discharge controller or other approved device, the regulation of which shall be directed by the Control Authority. An individual wastewater discharge permit may be issued solely for flow equalization.
(c) If the Director permits the pretreatment or equalization of discharges, the design and installation of the facilities for pretreatment or equalization shall be subject to review by and approval of the Director of the Ohio EPA and the Director of Public Utilities in accordance with ORC 6111.03. Plans, specifications, operating procedures and any other pertinent information relating to the proposed pretreatment or equalization facilities shall be submitted for approval and both approvals, obtained in writing prior to the start of construction if the effluent from such facilities is to be discharged into the public sewers. The review of such plans by the Approval Authority and the Control Authority shall in no way relieve the User from the responsibility of modifying the facilities as necessary to produce a discharge acceptable to the City of Toledo under the provisions of this chapter.
(d) Users with the potential to discharge flammable substances may be required to install, operate and maintain an approved combustible gas detection meter at the User's expense.
(e) As required in the City of Toledo's Industrial Waste Release Minimization Plan (IWRMP), the Control Authority, whenever deemed necessary, may require Users to restrict their discharge during peak flow periods or wet weather events; designate that certain wastewater be discharged only into specific sewers; relocate and/or consolidate points of discharge; separate sewage waste streams from industrial waste streams; and implement such other conditions as may be necessary to protect the POTW and determine the User's compliance with the requirements of this chapter.
