§ 52.035  PRETREATMENT FACILITIES.
   (A)   Industrial users shall provide wastewater treatment as necessary to comply with this chapter and shall achieve compliance with all categorical pretreatment standards, local limits and the prohibitions set out in §§ 52.015 through 52.020 within the time limitations specified by the EPA, the commonwealth or the Wastewater Superintendent, whichever is more stringent.
   (B)   Any facilities necessary for compliance shall be provided, operated and maintained at the user’s expense. Detailed plans describing the pretreatment facilities and operating procedures shall be submitted to the Wastewater Superintendent for review and approval, and shall be acceptable to the Wastewater Superintendent before construction of the facilities begin.
   (C)   The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facilities as necessary to produce a discharge acceptable to the town under the provisions of this chapter.
(1996 Code, § 168-11)  Penalty, see § 52.999
§ 52.036  ADDITIONAL PRETREATMENT MEASURES.
   (A)   Whenever deemed necessary, the Wastewater Superintendent may require industrial 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 waste streams from industrial waste streams, and such other conditions as may be necessary to protect the POTW and determine the industrial user’s compliance with the requirements of this chapter.
   (B)   The Wastewater Superintendent 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.
   (C)   Grease, oil and sand interceptors shall be provided when, in the opinion of the Wastewater 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 type and capacity approved by the Wastewater Superintendent 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 his or her expense.
   (D)   Users with the potential to discharge flammable substances may be required to install and maintain one or more approved combustible gas detection meters.
(1996 Code, § 168-12)  Penalty, see § 52.999
§ 52.037  ACCIDENTAL DISCHARGE/SLUG CONTROL PLANS.
   (A)   At least once every two years, the Wastewater Superintendent shall evaluate whether each user needs an accidental discharge/slug control plan.
   (B)   The Wastewater Superintendent may require any user to develop, submit for approval and implement such a plan.
   (C)   Alternatively, the Wastewater Superintendent may develop such a plan for any user.
   (D)   An accidental discharge/slug control plan shall address, at a minimum, the following:
      (1)   Description of discharge practices, including non-routine batch discharges;
      (2)   Description of stored chemicals;
      (3)   Procedures for immediately notifying the POTW of any accidental or slug discharge. As required by §§ 52.090 through 52.103, such notification must also be given for any discharge which would violate any of the prohibited discharges in §§ 52.015 through 52.020; and
      (4)   Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response.

§ 52.038  HAULED WASTEWATER.
   (A)   Septic tank waste may be introduced into the POTW only at locations designated by the Wastewater Superintendent, and at such times as are established by the Wastewater Superintendent. Such waste shall not violate §§ 52.015 through 52.020 or any other requirements established by the town. The Wastewater Superintendent may require septic tank waste haulers to obtain wastewater discharge permits.
   (B)   The Wastewater Superintendent may require haulers of industrial waste to obtain wastewater discharge permits. The Wastewater Superintendent may require generators of hauled industrial waste to obtain wastewater discharge permits. The Wastewater Superintendent also may prohibit the disposal of hauled industrial waste. The discharge of hauled industrial waste is subject to all other requirements of this chapter.
   (C)   Industrial waste haulers shall discharge loads only at locations designated by the Wastewater Superintendent. No load may be discharged without prior consent of the Wastewater Superintendent. The Wastewater Superintendent may collect samples of each hauled load to ensure compliance with applicable standards. The Wastewater Superintendent may require the industrial waste hauler to provide a waste analysis of any load prior to discharge.
   (D)   Industrial waste haulers shall provide a waste-tracking form for every load. This form shall include, at a minimum, the name and address of the industrial waste hauler, permit number, truck identification, names and addresses of sources of waste, and volume and characteristics of waste. The form shall identify the type of industry, known or suspected waste constituents, and whether any wastes are RCRA hazardous wastes.
