Additional pretreatment measures shall be installed and maintained at the user’s expense to the satisfaction of the town. If the Superintendent determines it is necessary to protect the POTW and/or ensure compliance with the town’s NPDES permit:
(A) The Superintendent may require users to retreat 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 waste streams from industrial streams, and such other conditions as may be necessary to protect the POTW and determine the user’s compliance with the requirements of this chapter.
(B) The Superintendent may require any person discharging into the POTW to install and maintain, on the user’s property and at the user’s expense, a suitable storage and flow-control facility to insure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
(C) Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
(D) Grease, oil, and sand interceptors shall be provided when, in the opinion of the Superintendent, 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. All interception units shall be of the type and capacity approved by the Superintendent and shall be located to be easily accessible for cleaning and inspection. The interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the user, at the user’s expense.
(E) Users who operate vehicular wash facilities shall provide, operate, and maintain pretreatment facilities and/or operational procedures required and approved by the Superintendent to control solids and preclude the discharge of toxics to the POTW.
(F) Users who operate food preparation facilities shall provide, operate, and maintain pretreatment facilities and/or operational procedures required and approved by the Superintendent to control the discharge of FOG and food solids to the POTW. This shall include the proper installation and maintenance of grease traps. The Superintendent reserves the right to determine appropriate maintenance intervals and to require associated documentation.
