(A) Nothing contained in this chapter shall be construed as preventing any special agreement between the city, the county and any user of the WWF whereby a wastewater of unusual strength or character may be accepted into the WWF subject to agreement between the two parties. No such agreement, however, shall be made that would allow the influent to the WWF to adversely affect operation of the treatment plant. The terms and conditions of such agreement are subject to change by the director during the life of the agreement as required for changes to NPDES permit limitations or limitations contained in permits issued by the State of Florida. Notification of such changes will be made similar to permit modifications as outlined in § 54.76.
(B) In no case (except for the formal grant of removal credits) will a special agreement waive compliance with any pretreatment standard. However, the IU may request a net gross adjustment to a categorical pretreatment standard in accordance with 62625.820, F.A.C, as hereby incorporated. Industrial users may also request a variance from the categorical pretreatment standards from the EPA. Such a request will be approved only if the IU can prove that factors relating to its discharge are fundamentally different from the factors considered by EPA when establishing that categorical pretreatment standard. An IU requesting a fundamentally different factor variance must comply with the procedural and substantive provisions in 62-625.700, F.A.C, as incorporated in § 54.31(E).
(C) Grease, oil and sand interceptors shall be provided by the IU when, in the opinion of the director they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil or sand; except that such interceptors shall not be required for residential users. Interception units shall be of type and capacity approved by the director and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected regularly and cleaned, as needed by the IU at their expense. Wastewater from any source requiring installation of a trap, interceptor, and/or separator, per Chapter 10 of the Florida Plumbing Code (as may be amended from time to time) may be considered industrial wastewater for the purpose of this chapter.
(D) Industrial users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
