(A) The following described substances, materials, waters, or waste shall be limited in discharges to the municipal system to concentrations or quantities which will not harm either the sewers, wastewater treatment process, or equipment; will not have an adverse effect on the receiving stream; will not cause violations of the NPDES regulations; or will not otherwise endanger lives, limb, public property, or constitute a nuisance. The Board may set limitations more severe than the limitations established in this chapter if in their opinion such more severe limitations are necessary to meet the above objectives. In forming this opinion as to the acceptability, the Board will give consideration to such factors as the quantity of subject waste in relation to flows and velocities in the sewers, materials of construction of the sewers, the wastewater treatment process employed, capacity of the wastewater treatment plant, and other pertinent factors. The limitations or restrictions on material or characteristics of waste or wastewaters discharged to the sanitary sewer which shall not be violated without approval of the Board are as follows:
(1) Wastewater having a temperature higher than 150°F (65°C) at the point of entrance to main sewer;
(2) Wastewater containing more than 25 mg/l of petroleum oil, nonbiodegradable cutting oils, or product of mineral oil origin;
(3) Wastewater from industrial plants containing floatable oils, fat, or grease;
(4) Any garbage that has not been properly shredded; (Garbage grinders may be connected to sanitary sewers from homes, hotels, institutions, restaurants, hospitals, catering establishments, or similar places where garbage originates from the preparation of food in kitchens for the purpose of consumption on the premises or when served by caterers.)
(5) Any waters or wastes containing iron, chromium, copper, zinc, cadmium, and similar objectionable or toxic substances to such degree that any such material received in the composite wastewater at the wastewater treatment works exceeds the limits established by the Board for such materials;
(6) Any waters or wastes containing odor-producing substances exceeding limits which may be established by the Board;
(7) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Board in compliance with applicable state or federal regulations;
(8) Quantities of flow, concentrations, or both which constitute a “slug,” as defined herein;
(9) 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; and
(10) Any water or wastes which, by Interaction with other water or wastes In the public sewer system, release obnoxious gases, form suspended solids which interfere with the collection system, or create a condition deleterious to structures and treatment processes. The Board shall require all discharges to conform to all NPDES permit requirements and any other specified State or Federal regulations.
(B) (1) 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 judgement of the Board may interfere with, pass through, or otherwise be incompatible with the wastewater facilities, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Board of Public Affairs may:
(a) Reject the wastes;
(b) Require pretreatment to an acceptable condition for discharge to the public sewers;
(c) Require control over the quantities and rates of discharge; and/or
(d) Require payment to cover added cost of handling and treating the wastes not covered by existing taxes or sewer charges.
(2) If the Board permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Board.
(3) When considering the above alternatives, the Board shall give consideration to the economic impact of each alternative on the discharger.
(C) Grease, oil, and sand interceptors shall be provided when, in the opinion of the Board, they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts, or any flammable wastes, sand, or other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Board, and shall be located as to be readily and easily accessible for cleaning and inspection. In the maintaining of these interceptors, the owner(s) shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates, and means of disposal which are subject to review by the Board. Any removal and hauling of the collected material not performed by the owner(s) personnel must be performed by currently licensed waste disposal firms.
(D) Where pretreatment or flow-equalizing facilities are provided or required for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner(s) at this expense.
(E) When required by the Board, the owner(s) of any property serviced by a building sewer carrying industrial wastes shall install a suitable structure together with the necessary meters and other appurtenances in the building sewer to facilitate observation, sampling, and measurement of the wastes. The structure, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Board. The structure shall be installed by the owner(s) at his or her expense and shall be maintained by him or her so as to be safe and accessible at all times.
(F) The Board may require a user of sewer services to provide information needed to determine compliance with this subchapter. These requirements may include:
(1) Wastewaters discharge peak rate and volume over a specified time period;
(2) Chemical analyses of wastewaters;
(3) Information on raw materials, processes, and products affecting wastewater volume and quality;
(4) Quantity and disposition of specific liquid, sludge, oil, solvent, or other materials important to sewer use control;
(5) A plot plan of sewers of the user’s property showing sewer and pretreatment facility location;
(6) Details of wastewater pretreatment facilities;
(7) Details of systems to prevent and control the losses of materials through spills to the municipal sewer; and
(8) Such other information as may be required by the village’s NPDES permit.
(G) 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. All tests shall conform to EPA Regulation Title 40 C.F.R. part 136 published October 16, 1973 In the Federal Register entitled "Guidelines Establishing Test Procedures for Analysis of Pollutants." Sampling methods, location, times, durations, and frequencies are to be determined on an individual basis subject to approval by the Board and other regulatory agencies.
(H) No provision of this chapter shall be construed as preventing any special agreement or arrangement between the village and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the village for treatment, subject to payment thereof in accordance with provisions of this subchapter.
(I) The village may enter to special agreement or arrangement with another village for treatment, subject to the provisions of this subchapter.
