(A) No person(s) shall discharge or cause to be discharged any polluted waters such as storm water, groundwater, roof runoff, subsurface drainage, or cooling water to any sewer, except storm water runoff from limited areas, which storm water may be polluted at times, may be discharges to the sanitary sewer by permission of the appropriate authority.
(B) Storm water other than that exempted under division (A) above, and all other unpolluted drainage, shall be discharged to the sewers as are specifically designated as combined sewers or storm sewers or to a natural outlet approved by the appropriate authority and other regulatory agencies.
(C) Unpolluted industrial cooling sewer or process sewers may be discharged, on approval of the appropriate authority, to a storm sewer, combined sewer, or natural outlet.
(D) No person(s) shall discharge or cause to be discharged any of the following described sewers or wastes to any public sewers:
(1) Any gasoline, benezine, naptha, fuel oil, or other flammable or explosive liquid, solid, or gas;
(2) Any sewers containing toxic or poisonous solids, or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any waste treatment process constitute a hazard to humans or animals, create a public nuisance, or create any hazard in the receiving sewers of the wastewater treatment plant;
(3) Any sewers 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 wastewater works; and/or
(4) Solid or viscous substance in quantities or of the size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the wastewater facilities, 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 and paper dishes, cups, milk containers, and the like, either whole or ground by garbage grinders.
(E) The following described substances, materials, sewers, or waste shall be limited in discharges to municipal systems 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; or will not otherwise endanger lives, limb, public property, or constitute a nuisance. The appropriate authority may set limitations lower than the limitations established in the regulations below is in his or her opinion such severe limitations are necessary to meet the above objectives. In forming his or her opinion as to the acceptability, the appropriate authority will give consideration to the 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, degree of treatability of the waste in the wastewater treatment plant, and other pertinent factors. The limitations or restrictions on materials or characteristics of waste or wastewaters discharged to the sanitary sewer which shall not be violated without approval of the appropriate authority are as follows:
(1) Wastewater containing more than 25 milligrams per liter of petroleum oil, nonbiodegradable cutting oils, or product of mineral oil;
(2) Wastewater having a temperature higher than 150°F (65°C);
(3) Wastewater from industrial plants containing floatable oils, fat, or grease;
(4) Any garbage that has not been properly shredded (see § 54.02). 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 sewers or wastes containing iron, chromium, copper, zinc, and similar objectionable or toxic substances to the degree that any such material received in the composite wastewater at the wastewater treatment plant exceeds the limits established by the appropriate authority for the materials;
(6) Any sewers or wastes containing odor-producing substances exceeding limits which may be established by the appropriate authority;
(7) Any radioactive wastes or isotopes of the half-life or concentration as may exceed limits established by the appropriate authority in compliance with applicable state or federal regulations;
(8) Quantities of flow, concentrations, or both which are constitute a slug as defined herein;
(9) Sewers or wastes containing substance which are not amendable to treatment or reduction by the wastewater treatment processes employed, or are amendable to treatment only to the degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving sewers; and/or
(10) Any sewer or wastes which, by interaction with sewer or wastes in the public sewer system, release obnoxious gases from solids which interfere with the collection system, or create a condition deleterious to structures and treatment processes.
(F) If any sewers or wastes are discharged or are proposed to be discharged to the public sewers, which sewers contain the substances or possess the characteristics enumerated in division (D) above, and which is the judgment of the appropriate authority, may have a deleterious effect upon the wastewater facilities, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the appropriate authority may:
(1) Reject the wastes;
(2) Require pretreatment to an acceptable condition for discharge to the public sewers;
(3) Require control over the quantities and rates of discharge; and/or
(4) Require payment to cover added cost of handling and treating the wastes not covered by existing taxes or sewer changes under the provisions of this section.
(G) When considering the above alternatives, the appropriate authority shall give consideration to the economic impact of each alternative on the discharger. If the appropriate authority 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 appropriate authority.
(H) Grease, oil, and sand interceptors shall be provided when, in the opinion of the appropriate authority, they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts, as specified in this section, or any flammable wastes, sand, or other harmful ingredients; except that the interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be a type and capacity approved by the appropriate authority, and shall be located as to a 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 materials and shall maintain records of the dates, and means of disposal which are subject to review by the appropriate authority. Any removal and hauling of the collected materials not performed by the owner(s) personnel must be performed by currently licensed waste disposal firms.
(I) Where pretreatment or flow-equalizing facilities are provided or required for any sewers or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner(s) at his or her expense.
(J) The appropriate authority may require a user of sewer services to provide information needed to determine compliance with this chapter. 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 specified liquid, sludge, oil, mud, 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; and/or
(7) Details of systems to prevent and control the losses of materials through spills to the municipal sewer.
(K) All measurements, tests, and analyses of the characteristics of sewers 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 Sewer and Wastewater, published by the American Public Health Association. Sampling methods, locations, times, durations, and frequencies are to be determined on an individual basis subject to approval by the appropriate authority.
(L) No statement contained in this chapter shall be construed as preventing any special agreement or arrangement between the town and any owner or concern whereby a waste of unusual strength or character may be accepted by the town for treatment.
