(A) No person shall discharge or cause to be discharged any of the following described waters or wastes to a public sewer:
(1) Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid, or gas;
(2) Any waters or wastes containing toxic 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 sewage treatment plant;
(3) Any waters or wastes having a pH lower than 5.5 or higher than 9.5 or having any other corrosive property capable of causing damage or hazard to structure, equipment, and personnel of the sewage works, or that interferes with any treatment process;
(4) Solid or viscous substances in quantities or of a 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, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, underground garbage, whole blood, paunch, manure, hair and fleshings, entrails, paper, dishes, cups, milk containers, and the like, either whole or ground by garbage grinders; and/or
(5) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters of the wastewater works, or to exceed the limitations set forth in the applicable Federal Categorical Pretreatment Standards or other pretreatment standards or regulations issued by USEPA or the IDEM. Toxic pollutants are identified pursuant to 33 U.S.C. § 1317(a), as amended.
(B) 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 Council that the 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. In forming its opinion as to the acceptability of these wastes, the Council will give consideration to the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant and other pertinent factors. The substances prohibited are:
(1) Any liquid or vapor having a temperature higher than 150°F or 65°C;
(2) 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 32°F and 150°F or 0°C and 65°C;
(3) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of 3/4 horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the Council;
(4) Any waters or wastes containing strong acid iron pickling wastes or concentrated plating solutions whether neutralized or not;
(5) Any waters or wastes containing iron, chromium, copper, zinc and similar objectionable or toxic substances; or wastes exerting an excessive chlorine requirement, to the degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Town Engineer for the materials. Under no circumstances shall a discharger release water or wastes containing concentrations of the following substances in amounts exceeding the stated value:
Parameter | 1-Day Maximum | 4-Day Average |
Arsenic |
1.0 | 0.2 |
Cadmium |
2.7 | 1.2 |
Copper |
5.0 | 3.5 |
Parameter | 1-Day Maximum | 4-Day Average |
Parameter | 1-Day Maximum | 4-Day Average |
Cyanide |
1.5 | 0.5 |
Lead |
2.0 | 0.8 |
Mercury |
0.1 | 0.005
|
Nickel |
5.0 | 2.5 |
Total chromium |
7.5 | 5.0 |
Zinc |
10.0 | 6.0 |
*All units mg/l | ||
(6) Any waters or wastes containing phenols or other taste or odor-producing substances in concentrations exceeding limits which may be established by the Council as necessary, after treatment of the composite sewage, to meet the requirements of the state, federal, or other public agencies of jurisdiction for the discharge to the receiving waters;
(7) Any radioactive wastes or isotopes of a half-life or concentration as may exceed limits established by the Council in compliance with applicable state or federal regulations;
(8) Any waters or wastes having a pH in excess of 9.5;
(9) Materials which exert or cause:
(a) 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);
(b) Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions);
(c) Unusual S.S., DBOD, BOD, ammonia, ammonia-nitrogen, phosphorus, or chlorine requirements in quantities as to constitute a significant load on the sewage treatment works; and/or
(d) Unusual volume of flow or concentration of wastes constituting “slugs” as defined in § 51.35.
(10) Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment only to the degree that the sewage treatment plant effluent can not meet the requirements of other agencies having jurisdiction over discharge to the receiving waters; and/or
(11) It shall be unlawful for any person to place, deposit, or 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.
(C) 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 division (B) of this section, and which in the judgment of the 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 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 the wastes to within the limits of normal sewage as defined;
(4) Require control or flow equalization of the 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 the wastes.
(D) If the 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 Board and subject to the requirements of all applicable codes, ordinances, and laws.
(E) 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.
(F) When required by the Town Engineer, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole, together with the necessary meters and other appurtenances in the building sewer, to facilitate observation, sampling, and measurement of the wastes. The manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Town Engineer. 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 at all reasonable hours for the purpose of inspection, observation, measurement, sampling, and testing.
(G) (1) All measurements, tests, and analyses of the characteristics of water and wastes to which reference is made in this subchapter shall be determined in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater, at the control manhole provided, or upon suitable samples taken at the 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.
(2) 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 of constituents upon the sewage works and to determine the existence of hazards to life, limb, and property.
(3) 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.
(H) 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 rates as are compatible with the rate ordinance codified in §§ 51.01 through 51.24.
