(A) Pretreatment facilities. Users shall provide wastewater treatment as necessary to comply with this chapter and wastewater permits issued under §§ 50.105 through 50.112 of this code and shall achieve compliance with all national categorical pretreatment standards, local limits and the prohibitions set out in § 50.085 of this code within the time limitations as specified by the 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 town for review, and shall be approved by the POTW Director before construction of the facility. The review of these 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 town 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 or consolidate points of discharge, separate sewage waste streams from industrial waste streams and 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 his or her property and at his or her 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) (a) Grease and oil traps or other interceptors shall be provided at the user’s expense, when that user operates an establishment preparing, processing or serving food or food products. Grease interceptors can be required in other industrial products. Grease interceptors can be required in other industrial or commercial establishments when they are necessary for proper handling of liquid wastes containing oil or grease in amounts in excess of 50 mg/l by weight fat soluble, or for any flammable wastes. All such traps, tanks, chambers or other interceptors shall be of a type and capacity approved by the town and shall be readily and easily accessible for cleaning and inspection. All such interceptors shall be serviced and emptied of the waste content as required, but not less often than every 30 days, in order to maintain their minimum design capability to intercept oils and greases from the wastewater discharged to the publicly owned sanitary sewer. Failure to comply can result in the implementation of the enforcement procedures as written in §§ 50.151 through 50.153 and 50.999 of this code.
(b) Wastes removed from grease interceptors shall not be discharged into the publicly owned sanitary sewer. The owner shall be responsible for the sanitary disposal of these wastes.
(c) A facility must keep interceptor cleaning records on file a minimum of three years. The following information must be kept on file: receipt for job performed signed by contractor and cost, clean out date, person responsible for cleaning, name of firm performing the clean out and the disposal method for and destination of material removed.
(4) Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
