(A) Prior approval for certain wastes. Review and acceptance by the Superintendent shall be obtained prior to the discharge into the public sewers by any person of sewage whose wastes have:
(1) A BOD greater than 200 milligrams per liter;
(2) A suspended solids content greater than 250 milligrams per liter; and/or
(3) Other contaminants or characteristics which, from their nature or quantity, might be harmful to the structures, processes or operations of the sewage works or to health, whether by themselves or through interacting with other wastes in the public sewers.
(B) Pretreatment facilities. When, after making such a review, the Superintendent concludes that, before the person discharges his wastes into the public sewers, he must modify or eliminate those constituents which would be harmful to the structures, processes or operations of the sewage works or injurious to health, then the person shall either modify his wastes at the point of origin or shall provide and operate at his own expense such preliminary treatment or processing facilities as may be determined to be necessary to render his wastes acceptable for admission to the public sewers.
(C) Prior approval of pretreatment facilities. Plans, specifications and other pertinent information relating to proposed preliminary treatment or processing facilities shall be submitted to the town for examination and approval and no construction of such facilities shall begin until the town, through its Board of Trustees, has given its written approval. Such approval shall not exempt the person from the obligation to make further reasonable adaptations of such facilities when such adaptations prove necessary to secure the results desired. Plans, specifications and other pertinent information shall also be submitted to the Stream Pollution Control Board for approval in accordance with Stream Pollution Control Board Resolution No. 15.
(D) Operation of pretreatment facilities. When such preliminary treatment facilities are provided, they shall be maintained continuously in satisfactory and effective operating condition by the person at his own expense and shall be subject to periodic inspection by the town. The person shall maintain suitable operating records and shall submit to the Superintendent such monthly summary reports of the character of the influent and effluent as the latter may prescribe.
(E) Grease and sand traps. Whenever the Board of Trustees determines that interceptors or traps are needed to protect the sewerage system or the operations of the wastewater treatment plant from grease, oil, sand or similar substances occurring in a customer's sewage, then such traps shall be installed by the customer on his own lines at his own expense and shall be so maintained by him that none of such substances can be carried over into the public sewers. All traps shall be subject to the town's approval as to construction, location and installation.
