(A) (1) No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
(a) Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas;
(b) Any waters or wastes containing toxic (as described in § 307(a) of the Clean Water Act, being 33 U.S.C. § 1317(a)) or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the wastewater treatment plant or cause the town to violate in any manner its NPDES permit;
(c) Any waters or wastes having a pH lower than 5.5 or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works or interfere with any treatment process;
(d) Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewage works such as, but not limited to, ashes, bones, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails, paper, dishes, cups, milk containers and the like, either whole or ground by garbage grinders;
(e) Any waters or wastes containing phenols or other taste or odor producing substances, in such concentrations exceeding limits which may be established by the Superintendent as necessary, after treatment of the composite sewage, to meet the requirements of the state, federal or other public agencies of jurisdiction of such discharge to the receiving waters;
(f) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Superintendent in compliance with applicable state or federal regulations;
(g) Any waters or wastes having pH in excess of 9.5;
(h) Wastewater having a temperature higher than 150°F (65°C);
(i) Wastewater containing more than 25 milligrams per liter of petroleum oil, non- biodegradable cutting oils or product of mineral oil origin;
(j) Wastewater from industrial plants containing floatable oils, fats or grease;
(k) Quantities of flow, concentrations or both which constitute a “slug”, as defined herein;
(l) Materials which exert or cause:
1. Unusual concentrations of inert suspended solids (such as, but not limited to, Fullers earth, lime slurries and lime residues) or of dissolved solids (such as, but not limited to, sodium chloride and sodium sulfate);
2. Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions); and/or
3. Unusual BOD, chemical oxygen demand or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.
(m) Any waters or wastes containing iron, chromium, copper, zinc and similar objectionable or toxic substances to such degree that any such material received in the composite wastewater at the sewage treatment works exceeds the limits established by the Superintendent for such materials;
(n) Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed, or are amenable to treatment only to such degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters;
(o) Any water or wastes which, by interaction with other water or wastes in the public sewer system, release obnoxious gases, from suspended solids which interfere with the collection system, or create a condition deleterious to structures and treatment processes; and
(p) Any water or wastes subject to the categorical pretreatment standards pursuant to 40 C.F.R. part 403 (and the like).
(2) (a) If any wastes or waters are discharged, or are proposed to be discharged, to the public sewers, which waters contain the substances or possess the characteristics enumerated in this division (A) and which, in the judgment of the Superintendent, may have a deleterious effect upon the sewage works, processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Superintendent may:
1. Require any industries to submit information on wastewater quantities and characteristics and obtain prior approval for discharges;
2. Reject the wastes in whole or in part for any reason deemed appropriate by the town;
3. Require pretreatment of such wastes to within the limits of normal sewage, as defined herein;
4. Require control or flow equalization of such wastes so as to avoid any “slug” loads or excessive loads that may be harmful to the treatment works; or
5. Require payment of a surcharge on any excessive flows or loadings discharged to the treatment works to cover the additional costs of having capacity for and treating such wastes.
(b) If the Superintendent permits the pretreatment or equalization of waste flows, the design and installation of the plant and equipment shall be subject to the review and approval of the Superintendent and subject to the requirements of all applicable codes, ordinances and laws.
(3) Where preliminary treatment or flow-equalizing 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 expense.
(4) When required by the Superintendent, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located and shall be constructed in accordance with plans approved by the Superintendent. The manhole shall be installed by the owner at his or her expense and shall be maintained so as to be safe and accessible at all times. Agents of the town, the State Water Pollution Control Agencies and the U. S. Environmental Protection Agency shall be permitted to enter all properties for the purpose of inspection, observation, measurement, sampling and testing.
(5) The Superintendent may require a user of sewer service to provide information needed to determine compliance with this subchapter. These requirements may include:
(a) Wastewater discharge peak rate and volume over a specified time period;
(b) Chemical analyses of wastewater;
(c) Information on raw materials, processes and products affecting wastewater volume and quality;
(d) Quantity and disposition of specific liquid, sludge, oil, solvent or other materials important to sewer use control;
(e) A plot plan of sewers of the user’s property showing sewer and pretreatment facility location;
(f) Details of wastewater pretreatment facilities; and
(g) Details of systems to prevent and control the losses of materials through spills to the municipal sewers.
(B) Unpolluted water from air conditioners, cooling, condensing systems or swimming pools shall not be discharged into the town’s sewer system.
