(A) No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
(1) Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas;
(2) Any waters or wastes containing toxic, as described in the Clean Water Act, § 307(a), being 33 U.S.C. 1317(a), or poisonous solids, liquids or gases in a 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 sewage plant;
(3) Any waters or wastes having a pH lower than 5.5 or having any other corrosive property capable of causing damage or a hazard to structures, equipment and personnel of the sewage works or interfering with any treatment process;
(4) Solid or viscous substances in such quantities or of such size as is capable of causing an obstruction to the flow in sewers or otherwise interfering with proper operation of the sewage works, such as, but not limited to, ashes, 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;
(5) Any waters or wastes containing phenols or other taste- or odor-producing substances in concentrations exceeding the 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 over such discharge to the receiving waters;
(6) 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;
(7) Any waters or wastes having a pH in excess of 9.5;
(8) Waters or wastes containing substances which are not amendable to treatment or reduction by the sewage treatment processes employed, or which are amendable to treatment only to such a degree that the sewage treatment effluent cannot meet the requirements of the other agencies having jurisdiction over discharge to the receiving waters; or
(9) Materials which exert or cause:
(a) Unusual concentrations of inert suspended solids, such as, but not limited to, fuller’s earth, lime slurries and lime residues, or unusual concentrations of dissolved solids, such as, but not limited to, sodium chloride and sodium sulfate;
(b) Excessive discoloration, such as, but not limited to, dye wastes and vegetable-tanning solutions;
(c) Unusual BOD, chemical oxygen demand or chlorine requirements in such quantities so as to constitute a significant load on the sewage treatment works; or
(d) Unusual volumes of flow or concentrations of wastes constituting “slugs” as defined herein.
(B) (1) If any waters or wastes are discharged or proposed to be discharged to the public sewers, which waters containing the substances or possessing the characteristics enumerated in division (A) above, and which in works, processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Superintendent may:
(a) Require any industry to submit information on wastewater quantities and characteristics and to obtain prior approval for discharges;
(b) Reject the wastes in whole or in part for any reason deemed appropriate by the town;
(c) Require pretreatment of such wastes to within the limits of normal sewage as defined;
(d) Require control or flow equalization of such wastes so as to avoid any “slug” loads or excessive loads which may be harmful to the treatment works; or
(e) Require the 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.
(2) If the Superintendent permits the pretreatment or equalization of waste flows, then 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.
(C) 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.
(D) When required by the Superintendent, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole in the building sewer together with such necessary meters and other appurtenances 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’s Water Pollution Control Agency and the U.S. Environmental Protection Agency shall be permitted to enter all properties for the purpose of inspection, observation, measurement, sampling and testing.
(E) (1) All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater, published by the American Public Health Association, and shall be determined at the control manhole provided or upon suitable samples taken at said control manhole, except that applications for NPDES permits and reports thereof shall be conducted in accordance with the rules and regulations adopted by the USEPA as per 40 C.F.R. part 136.
(2) In the event that no special manhole has been required, the control manhole shall be considered to be the downstream manhole in the public sewer nearest to the point where the building sewer is connected. Sampling shall be carried out by customarily-accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property. The particular analysis involved will determine whether a 24-hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from 24-hour composites of all outfalls, whereas pH is determined from periodic grab samples.
(F) No statement contained in this section shall be construed as preventing any special agreement or arrangement between the town and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the town for treatment, subject to payment therefor by the industrial concern at such rates as are compatible with rate provisions.
