§ 50.043 WASTES SUBJECT TO APPROVAL; PRETREATMENT INTERCEPTORS.
   (A)   The admission into the town sewerage system of any waters or wastes having a five-day biochemical oxygen demand greater than 300 parts per million by weight of suspended solids, containing any quantity of substances having the characteristics described above, or having an average daily flow of greater than 25,000 gallons shall be subject to the review and approval of the Public Works Director.
   (B)   (1)   If necessary, the Public Works Director may require an owner to provide, at his or her sole expense, such preliminary treatment of wastes as may be necessary to reduce the BOD to 300 parts per million and the suspended solids to 350 parts per million by weight, reduce the objectionable characteristics or constituents to within the maximum limits provided in this section, or control the quantities and rates of discharge of such waters or wastes. Plans, specifications, and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for approval of the Public Works Director and the Engineering Division of the State Board of Health. No construction of such facilities shall be commenced until approved by the Director in writing.
      (2)   Where preliminary treatment facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her own expense. The owner shall submit compliance reports from a qualified testing laboratory when required by the Director.
   (C)   If necessary for the proper handling of liquid wastes containing grease or oil in excessive amounts or any flammable wastes, sand, or other harmful ingredients, the Public Works Director may require the owner to provide, at his or her sole expense, grease, oil, and sand interceptors; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Director and shall be located as to be readily and easily accessible for cleaning and inspection. Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, water-tight, and equipped with easily removable covers which, when bolted in place, shall be gas-tight and water-tight.
