(10) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Town Council in compliance with applicable state or federal regulations.
(C) (1) No person shall discharge or cause to be discharged the following described substances, materials, or wastes if it appears likely in the opinion of the Town Council that such wastes can harm either the sewers, sewage treatment process, or equipment, have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property, or constitute a nuisance.
(2) In forming its opinion as to the acceptability of these wastes, the Town Council will give consideration to the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, and other pertinent factors.
(3) The substances prohibited are:
(a) Any liquid or vapor having a temperature higher than 150º F or 65º C;
(b) Any water or waste containing fats, wax, grease, or oils, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between 32ºF and 150º F or 0º C and 65º C;
(c) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the Town Council;
(d) Any waters or wastes containing strong acid iron pickling wastes or concentrated plating solutions whether neutralized or not;
(e) Any waters or wastes containing iron, chromium, copper, zinc, and similar objectionable or toxic substances; or wastes exerting an excessive chlorine requirement, to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Superintendent for such materials;
(f) Any waters or wastes containing phenols or other taste or odor producing substances, in such concentrations exceeding limits which may be established by the Town Council as necessary, after treatment of the composite sewage, to meet the requirements of the state, federal or other public agencies of jurisdiction for such discharge to the receiving waters;
(g) Any waters or wastes having a pH in excess of 9.0;
(h) Materials which exert or cause:
1. Unusual concentrations of inert S.S. (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);
3. Unusual S.S., CBOD, BOD, ammonia-nitrogen, phosphorus, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works; or
4. Unusual volume of flow or concentration of wastes constituting “slugs” as defined herein.
(i) Waters or wastes containing substances which are not amendable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment only to such degree that the sewage treatment plant effluent will be compromised; and
(j) It shall be unlawful for any person to place, deposit, permit to be deposited, or discharged in any manner whatsoever, any substance into a sewer at a point different than the proposed sewer connection to the sanitary sewer system.
(D) If any waters or wastes are discharged, or are proposed to be discharged, to the public sewers, which waters contain the substances or possess the characteristics enumerated in this section, and which in the judgment of the Town Council may have a deleterious effect upon the sewage works, processes, equipment, or receiving waters, or otherwise create a hazard to life or constitute a public nuisance, the Town Council may:
(1) Require new industries or industries with significant increase in discharges to submit information on wastewater 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 domestic sewage as defined;
(4) Require control of flow equalization of such wastes so as to avoid any “slug” loads or excessive loads that may be harmful to the treatment works; and/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, if the Town Council 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 Town Council and subject to the requirements of all applicable codes, ordinances, and laws.
(E) Interceptors shall be provided by the discharger as necessary for the removal of grease, flammable wastes, sand, or other harmful substances. All interceptors shall be of a type and capacity approved by the Town Council or its designee, and shall be readily accessible for cleaning and inspection. The owner and/or operator of interceptor equipment shall be required to maintain certified records as to time and date of cleaning and inspection.
(F) When a discharger is required to provide preliminary treatment, including interceptors or flow equalization facilities, such equipment shall be maintained by the discharger in satisfactory operating condition as determined by the Town Council or its designee.
(G) When required by the Superintendent, the owner or 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 town. The manhole shall be installed by the owner at his or her expense, and shall be maintained by him or her so as to be safe and accessible at all times. Agents of the town, the State Water Pollution Control Agencies and the USEPA shall be permitted to enter all properties for the purpose of inspection, observation, measurement, sampling, and testing.
(H) All measurements, tests, and analyses of the characteristics of water and wastes to which reference is made in this chapter, shall be conducted using the methods and procedures in 40 C.F.R. part 136, and shall be determined at the control manhole provided, or upon suitable samples taken at said control manhole, except for application for NPDES permits and report thereof such shall be conducted in accordance with rules and regulations adopted by the USEPA, 40 C.F.R. Part 136 and any subsequent revisions subject to approval by the town. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect to 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 S.S. analyses are obtained from 24-hour composites of all outfalls whereas pHs are determined from periodic grab samples.
(I) No statement contained in this subchapter shall be construed as preventing any special agreement or arrangement between the town and any industrial concern whereby an industrial waste or 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 the rate ordinance, provided, however, that no special agreement or arrangement may be made with the town which results in the violation of National Pretreatment Standards or local limits.
