(a) No person shall cause or permit an unusual discharge to the public sewers without first obtaining the approval of the Director. An unusual discharge to the City sewer system is one that meets any of the following criteria: (i) is discharged through a non-permanent entry point into the sewer system; (ii) is not the result of a normal business operation; or (iii) is a one-time special discharge.
(b) The unusual discharge shall not exceed any of the concentrations listed in Section 930.05(c). In addition, the discharge shall not exceed the concentrations except as stated in Appendix A.
(c) Any person seeking to release an unusual discharge to the sanitary sewer system shall submit an application and pay an application fee to the Division of Environmental Services as stated in Appendix A.
(d) If the unusual discharge application is approved, the User shall be issued a discharge permit after paying a permit fee to the Division of Environmental Services based upon the volume of flow as stated in Appendix A.
(e) The unusual discharge permit shall be valid for a period of one month from the date of issuance. In the event a request is made to discharge for a period in excess of one month, the Director may grant an extension of the existing permit or may enter the User into the Industrial Pretreatment Program for the period of time corresponding to the discharge. The User shall make arrangements with the Division of Sewers and Drainage to determine an acceptable discharge point to the sanitary sewer system. A flow meter or other method acceptable to Division of Environmental Services must be used to determine the amount of waste discharged to the sewer system. If the User is unable to obtain a meter, the City will use the full capacity of the containment device used to hold the wastewater prior to discharge for billing purposes.
(f) In addition to the fees charged under this section, any person discharging wastewater with an unusual strength or character shall also pay the charges specified in Section 929.03(c).
(g) No provision of this chapter shall prevent an agreement between the City and the User whereby wastewater with unusual strength or character may be discharged to the treatment works subject to additional charges and fees set forth in the agreement. No agreement entered into between the City and a User will violate the general and specific discharge limitations set forth in this chapter or any other federal or state or local regulations or standards including, without limitation, the National Categorical Pretreatment Standards.
(h) Unusual waste includes, without limitation, unregulated process waste, leachate, condensate or any other discharge related to a landfill or landfill type operation as set forth in Section 929.03(c). Each User will submit analytical data and the maximum proposed volumes to be discharged, and the Control Authority will allocate concentrations on an individual basis. The allocated concentrations may not exceed the City of Toledo's MAIL's. Each individual limit will be based on the mass based limits for all pollutants of concern as set forth in Section 930.05(c).
