2.7 Dilution A user shall not increase the use of process water, or in any way attempt to dilute a discharge, as a partial or complete substitute for adequate treatment to achieve compliance with an applicable pretreatment standard or requirement unless expressly authorized by an applicable pretreatment standard or requirement. The Director may impose mass limitations on users which he believes may be using dilution to meet applicable pretreatment standards or requirements, or in other cases when the imposition of mass limitations is appropriate. 2.8 Pretreatment Facilities A. General: Users shall provide all known, available, and reasonable methods of prevention, control, and treatment (AKART) as required to comply with this ordinance and shall achieve compliance with all applicable pretreatment standards and requirements set out in this ordinance within the time limitations specified by the EPA, the State, or the Director, whichever is more stringent. Any facilities required to pretreat wastewater to a level acceptable to the City shall be provided, operated, and maintained at the user's expense. In addition, the Director may establish Best Management Practices (BMPs) for particular groups of users. These BMPs may include, but are not limited to types or methods of pretreatment technology to be used, methods of source control, minimum maintenance requirements, dragout prevention practices, spill prevention practices, or other requirements as deemed necessary. When required by the Director, an engineering report, including detailed plans showing the preireatment facilities and operating procedures shall be submitted to the City for review, and shall be acceptable to the City before construction of the facility. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an acceptable discharge to the City under the provisions of this ordinance. Within ninety (90) days after the completion of the wastewater pretreatment facility, the discharger shall furnish as built drawings and its operations and maintenance procedures. Any subsequent significant changes in the pretreatment facility or method of operation shall be reported to and approved by the Director prior to the initiation of the changes. New sources, and new users determined to be Significant Industrial Users (SIU's) must have pretreatment facilities installed and operating prior to discharge, if required. B. Pretreatment Facilities for FOG: The City shall approve installation of grease removal and treatment systems. Systems shall meet the following criteria. 1) All grease traps shall, at a minimum, comply with the requirements of Section 7 of the UPC. 2) No dishwashers are to be discharged to grease traps. 14
