Industrial cooling water or unpolluted process waters may be discharged upon approval of the Village Superintendent to a storm sewer or natural outlet.
(C) Prohibited discharges. Except as hereinafter provided, no person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewer:
(1) Any liquid or vapor having a temperature higher than 150°F;
(2) Any water or waste which may contain more than 100 parts per million by weight of fat, oil, or grease;
(3) Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquids, solid, or gas;
(4) Any garbage that has not been properly shredded;
(5) Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, paunch manure, or any other solid or viscous substance capable of causing obstruction to flow in sewers or other interference with the proper operation of the sewage works;
(6) Any waters or wastes having corrosive properties capable of causing damage or hazard to structures, equipment, and personnel of the sewage works;
(7) Any waters or wastes containing a toxic or poisonous substance in sufficient quantity to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, or create any hazard in receiving waters of the sewage treatment plant;
(8) Any waters or wastes containing suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant;
(9) Any noxious or malodorous gas or substance capable of creating a public nuisance; or
(10) Any waters containing in excess of 20 parts per million of total phosphorus where user discharges in excess of 100,000 cubic feet of water per month, or in excess of 125 pounds of phosphorus per month to a sewer when using less than 100,000 cubic feet of water per month. Any user exceeding these limits will be subject to a surcharge based upon additional cost of treatment.
(D) Interceptors. Grease, oil, and sand interceptors shall be provided when, in the opinion of the Village Superintendent, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts or any flammable wastes, sand, and other harmful ingredients, except that, such interceptors shall not be required for private living quarters or dwelling units, and all interceptors shall be of a type and capacity approved by the Village Superintendent and shall be located as to be readily and easily accessible for cleaning and inspection. Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, water-tight, and equipped with easily removable covers which when bolted in place shall be gas-tight and water-tight.
(E) Maintenance of interceptors. Where installed, all grease, oil, and sand interceptors shall be maintained by the owner, at his or her expense in continuously efficient operation at all times.
(F) Surcharges; preliminary treatment.
(1) Any user discharging to a public sewer in excess of 10,000 cubic feet of waste water per month, having:
(a) A five-day BOD greater than 300 parts per million by weight; or
(b) Containing more than 350 parts per million by weight of suspended solids, or containing any quantity or substance having characteristics described in division (C) above, will be subject to a surcharge based upon additional cost of treatment.
(2) Any user discharging to a public sewer in excess of 100,000 cubic feet of waste water per month, having:
(a) A five-day BOD greater than 100 parts per million by weight; or
(b) Containing more than 200 parts per million by weight of suspended solids, will be subject to a surcharge based upon additional cost of treatment where necessary, in the opinion of the Village Superintendent, the owner shall provide, at his or her expense, such preliminary treatment as may be necessary to reduce objectionable characteristics or constituents to within the maximum limits.
(3) Plans, specifications, and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for approval of the Village Superintendent and no construction of such facilities shall be commenced until said approvals are obtained in writing.
(G) Maintenance of preliminary treatment facilities. Where preliminary treatment 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.
(H) Control manhole. When required by the Village Superintendent, the owner of any property served by a building sewer carrying industrial wastes shall install a suitable control manhole 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 Village Superintendent. 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.
(I) Measurements, tests, and analyses. All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in divisions (C) and (H) above shall be determined in accordance with Standard Methods for Examination of Water and Sewage, and shall be determined at the control manhole provided for in division (H) above or upon suitable samples taken at said control manhole. 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.
(J) Special agreements. No statement contained in this section 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, subject to payment therefor by the industrial concern.
