(A) Regulatory actions. If wastewaters containing any substance described herein are discharged or proposed to be discharged into the wastewater treatment system of the town or to any sewer system tributary thereto, the Director may take any action necessary to:
(1) Prohibit the discharge of such wastewater;
(2) Require a user to demonstrate that in-plant modifications will reduce or eliminate the discharge of such substances in conformity with this chapter;
(3) Require pretreatment, including storage facilities, or flow equalization necessary to reduce or eliminate the objectionable characteristics or substances so the discharge will not violate this chapter;
(4) Require the person making, causing, or allowing the discharge to pay any additional cost or expense incurred for handling and treating excess loads imposed on the wastewater treatment system; and
(5) Take such other remedial action as may be deemed to be desirable or necessary to achieve the purpose of this chapter.
(B) Submission of plans. Where pretreatment or equalization of wastewater treatment system is required, plans, specifications, and other pertinent data or information relating to such pretreatment or flow-control facilities shall first be submitted to the Director for review and approval. Such approval shall not exempt the discharge of such facilities from compliance with any applicable code, ordinance, rule, regulation, or order of any governmental authority. Any subsequent alterations or additions to such pretreatment of flow-control facilities shall not be made without due notice to and prior approval of the POTW Director.
(C) Pretreatment facilities operations. If pretreatment or control of waste flows is required, such facilities shall be maintained in good working order and operated as efficiently as possible by the user at his or her own cost and expense, subject to the requirements of this chapter and all other applicable codes, ordinances, and laws.
(D) Admission to property.
(1) Whenever it shall be necessary, for the purposes of these rules and regulations, the Director or designated representative, upon the presentation of credentials, may enter upon any property or premises at reasonable times for the purpose of:
(a) Copying any records required to be kept under the provisions of this chapter;
(b) Inspecting any monitoring equipment or method; and/or
(c) Sampling any discharge of wastewater to the treatment works.
(2) The Director or designated representative may enter upon the property at any hour under emergency circumstances.
(E) Protection from accidental discharge. Each industrial user shall provide protection from accidental discharge of prohibited materials or other wastes regulated by this chapter. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the user’s own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the POTW Director for review and shall be approved by him or her before construction of the facility. Review and approval of such plans and operating procedures shall not relieve the industrial user from the responsibility to modify his or her facility as necessary to meet the requirements herein.
(F) Reports of accidental discharge. If, for any reason, a user does not comply with or will be unable to comply with any prohibition or limitation herein, the user responsible for such discharge shall immediately notify the Director so the corrective action may be taken to protect the wastewater treatment system. In addition, a written report addressed to the Director detailing the date, time, and cause of the discharge and corrective action taken to prevent future discharges shall be filed by the responsible user within five days of the occurrence of the noncomplying discharge. Such limitations include:
(1) A BOD greater than 300 mg/l;
(2) Containing COD of more than 600 mg/l;
(3) Containing suspended solids of more than 300 mg/l;
(4) Containing ammonia of more than 15 mg/l; or
(G) Grease, oil, and sand interceptors. Grease, oil, and sand interceptors shall be provided when, in the opinion of the approving authority, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts or any flammable wastes, sand, or other harmful ingredients; except, such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be maintained by the owner at his or her expense in continuously efficient operation at all times.
(H) Notices. Notice shall be given the approving authority when normal industry operations will be interrupted for 72 hours or longer and wastes will not be available for discharge or when a change of process is contemplated or malfunction of the treatment facility occurs or is anticipated which will alter demands on the municipal treatment facilities. Normal operations shall include allowance for legal holidays and other announced plan shutdowns.
(I) Preliminary treatment or holding facilities.
(1) Where preliminary treatment or holding facilities are provided for any purpose, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.
(2) There shall be no discharge of wastes requiring pretreatment either directly or indirectly to the town’s sewer system without first notifying and obtaining approval from the approving authority.
