§ 54.004 PRETREATMENT FACILITIES.
   (A)   Users shall provide wastewater treatment as necessary to comply with this code and shall achieve compliance with all categorical pretreatment standards, local limits and the prohibitions set out in § 54.020 of this chapter within the time limitations specified by EPA, the state or the Town Manager, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated and maintained at the user’s expense. Detailed plans describing such facilities and operating procedures shall be submitted to the Town Manager for review, and shall be acceptable to the Town Manager before such facilities are constructed. The Town Manager may request such additional information as is necessary for a full review of the plans.
      (1)   Within ten days of receiving all information requested by the Town Manager, the Town Manager shall schedule a consultation meeting with the user or the user’s representative at which time the Town Manager may request the user to prepare a mitigation plan that modifies the facility operation or design to ensure compliance with the town code and pretreatment standards.
      (2)   Within 20 days of the consultation meeting, the Town Manager may, by written memorandum, approve the facility plan incorporating any alterations, modifications or conditions deemed necessary to ensure that the facility will comply with town code and pretreatment standards, or may deny the facility plan if the constructed facility will not meet town code or pretreatment standards.
      (3)   In the event that the Town Manager determines that plans submitted by the user require further technical expertise may authorize the use of appropriate technical assistance in evaluating and/or modifying the plan and shall further establish at that time a time table for the completion of the study and construction or installation of the proposed facility.
      (4)   As to significant industrial users, the timetable for the construction of pretreatment facilities may, at the discretion of the Town Manager, be coordinated with the issuance of a wastewater discharge permit as set forth in §§ 54.035 through 54.042 of this chapter.
   (B)   (1)   Whenever deemed necessary, the Town Manager 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 waste streams, and such other conditions as may be necessary to protect the POTW and determine the user’s compliance with the requirements of this code.
      (2)   The Town Manager may require any person discharging into the POTW to install and maintain, on his, her or 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 Town Manager, 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 Town Manager 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, her or their expense.
      (4)   Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
   (C)   (1)   At least once every two years, the Town Manager shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan. the Town Manager may require any user to develop, submit for approval and implement such a plan. Alternatively, the Town Manager may develop such a plan for any user.
      (2)   An accidental discharge/slug control plan shall address, at a minimum, the following:
         (a)   Description of discharge practices, including non-routine batch discharges;
         (b)   Description of stored chemicals;
         (c)   Procedures for immediately notifying the Town Manager of any accidental or slug discharge, as required by § 54.060 of this chapter; and
         (d)   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.
