(A) Pretreatment facilities. Users shall provide wastewater treatment as necessary to comply with this chapter and wastewater permits issued under § 51.051 and shall achieve compliance with all national categorical pretreatment standards, local limits, and the prohibitions set out in § 51.015 within the time limitations as specified by EPA, the state, or the POTW Director, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the county for review, and shall be approved by the POTW Director before construction of the facility. The review of the 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 county under the provisions of this chapter. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be approved by the POTW Director prior to the user's initiation of the changes.
(B) Additional pretreatment measures.
(1) Whenever deemed necessary, the POTW Director may require users to restrict their discharge during 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 any other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this chapter.
(2) The POTW Director may require any person discharging into the POTW to install and maintain, on their property and 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.
(3) Grease, oil, and sand interceptors shall be provided when, in the opinion of the POTW Director, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil, and sand; except that the interceptors shall not be required for residential users. All interception units shall be of type and capacity approved by the POTW Director and shall be so located to be easily accessible for cleaning and inspection. The interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the user at their expense.
(4) Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
