or the general and specific prohibitions in Section 10-2 of this Article, as is allowed by 40 CFR 403.4. Section 10-2.6 Dilution. No user shall ever 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 the limitations contained in the National Categorical Pretreatment Standards, unless expressly authorized by an applicable pretreatment standard, or in any other pollutant-specific limitation developed by the County or State. Section 10-2.7 Pretreatment of Wastewater. a. Pretreatment Facilities Users shall provide necessary wastewater treatment as required to comply with this Article, wastewater permits issued under Section 10-4.2 of this Article and shall achieve compliance with all National Categorical Pretreatment Standards, local limits and the prohibitions set out in Section 10-2.1 of the article with in the time limitations as specified by the EPA, the State, or the Executive Director, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user's expense. Users shall not discharge wastewater requiring treatment either directly or indirectly to the County's wastewater treatment system without first notifying and obtaining approval from the Administrator. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the Authority for review, and shall be approved by the Executive Director before construction of the facility. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the Authority under the provisions of this Article. Any subsequent changes in the pretreatment facilities or methods of operation shall be reported to and be acceptable to the Executive Administrator prior to the user's initiation of the changes. Additional Pretreatment Measures. 1. Whenever deemed necessary, the Executive Director may require users to restrict their discharge peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this Article. Grease, oil and sand interceptors shall be provided when, in the opinion of the Executive Director, they are necessary for the proper handling of wastewater containing grease in excessive amount of grease and oil, or sand; except that such interceptors shall not be required for residential users. All restaurants and slaughtering operations shall have grease interceptors or grease removal facilities. All interception units shall be of type and capacity approved by the Executive Director and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the user at their expense. Flow equalization. The Executive Director may require any person discharging into the POTW to install and maintain, on the property at their expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization. Such facility shall have a capacity of at least eighty (80%) percent of the normal volume of one (1) twenty- four hour production period of wastewater and outlet to the sewer controlled by a waterworks-type controller, or other approved device, the setting of which shall be directed by the Executive Director. 45
