(A) No person(s) shall discharge or cause the discharge of any unpolluted waters such as storm water, surface water, ground water, roof runoff, subsurface drainage or cooling water to any wastewater facility, except storm water runoff from limited areas, which storm water may be polluted at times, and shall only be discharged into the wastewater system by permission of the town and the State Department of Environmental Quality.
(B) Storm water other than that exempted under division (A) above and all other unpolluted drainage shall be discharged to the wastewater facilities as are specifically designated as combined sewers or storm sewers, or to natural outlets approved by the town and the State Department of Environmental Quality. Unpolluted industrial cooling water or process waters shall also be discharged, to a storm sewer, combined sewer or natural outlet as approved by the town or the State Department of Environmental Quality.
(C) (1) No person(s) shall discharge or cause to be discharged any of the following described water or wastes to any wastewater facilities:
(a) Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas;
(b) Any waters containing toxic or poisonous solids, liquids or other wastes, to contaminate or interrupt any sewage treatment process, constitute a hazard in or have an adverse effect on the waters receiving any discharge from the works;
(c) Any waters 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
(d) 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 wastewater facilities such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastic, wood, underground 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.
(2) Each user that discharges any toxic pollutants, which cause damage to the town wastewater system, shall be liable to the town for the damage and for all expenses incurred by the town in repairing those system facilities.
(D) The following described substances, materials, waters or wastes shall be limited in discharges to the town wastewater system to concentrations or quantities which will not harm either the sewers, the sludge, the wastewater system, the wastewater system process or equipment, will not have an adverse effect on the receiving stream, or will not otherwise endanger lives, public property or constitute a nuisance. The town may set limitations more severe than the limitations established in the regulations below if more severe limitations are necessary to meet the above objectives. In setting these requirements, the town will give consideration to such factors as the quantity of the subject waste in relation to flows and velocities in the wastewater system, materials of construction of the sewers the wastewater treatment process employed, capacity of the sewers, capacity of the system, and other pertinent factors. The limitations or restrictions on materials or characteristics of wastewaters discharged to the wastewater system which shall not be violated without approval of the town are as follows:
(1) Wastewater having a temperature higher than 150°F (65°C);
(2) Wastewater containing more than 25 milligrams per liter of petroleum oil, non-biodegradable cutting oils or products of mineral oil origin;
(3) Wastewater from industrial plants containing floatable oil, fat or grease;
(4) Any garbage that has not been properly shredded. Garbage grinders may be connected to wastewater sewers from homes, hotels, institutions, restaurants, hospitals, catering establishments or similar places where garbage originates from the preparation of food in commercial kitchens for the purpose of consumption on the premises;
(5) Any waters or wastes containing iron, chromium, copper, zinc and similar objectionable or toxic substances to a degree that any material received in the composite wastewater at the wastewater treatment works exceeds the limits established by the state for the materials;
(6) Any waters or wastes containing odor-producing substances exceeding limits which may be established by the state;
(7) Any radioactive wastes or isotopes of a half-life of concentration as may exceed limits established in compliance with applicable state or federal regulations;
(8) Quantities of flow, concentration or both which constitute a “slug”, as defined herein;
(9) Water 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 a 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 wastewater system, release obnoxious gases, form suspended solids which interfere with the collection system, or create a condition deleterious to structures and treatment processes.
(E) If any water or wastes are discharged or are proposed to be discharged to the wastewater system, which waters contain the substances or possess the characteristics enumerated in division (D) above, and which are determined by the town to have a deleterious effect upon the wastewater system, processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the town may:
(1) Reject the wastes;
(2) Require pretreatment to an acceptable condition for discharge to the wastewater system;
(3) Require control over the quantities and rates of discharge, and wastes not covered by existing service use charges under the provisions of this subchapter. If the town permits the pretreatment or equalization of waste flows, the design and installation of the equipment shall be subject to the review and approval of the town and the State Department of Environmental Quality;
(4) A plot plan of facilities on the user’s property showing sewer and pretreatment facility location;
(5) Details of wastewater pretreatment facilities; and
(6) Details of system to prevent and control the losses of materials through spills to the wastewater system.
(F) All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this policy shall be determined in accordance with the aquifer protection permit for the system and the State Department of Health Services. Sampling methods, location, times, durations and frequencies are to be determined on an individual basis according to the aquifer protection permit for the system.
(G) No provision in this subchapter shall be construed as preventing a special agreement or arrangement between the town and an industrial user whereby industrial waste of unusual strength or character may be accepted by the town for treatment.
