(A) No person shall discharge, or cause to be discharged, any stormwater, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters to any sanitary sewer. (Ord. 9-16-85)
(B) Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers or to a natural outlet approved by the superintendent of public works. Industrial cooling water or unpolluted process waters may be discharged, on approval of the superintendent of public works, to a storm sewer or natural outlet. (Ord. O-3-16-1, 3-7-2016)
(C) No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
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 having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works.
4. Solid or viscous substances in quantities or of such 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, unground garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.
(D) No person shall discharge or cause to be discharged the following described substances, materials, waters or wastes if it appears likely in the opinion of the superintendent of public works that such 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 his opinion as to the acceptability of these wastes, the superintendent of public works shall give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant, and maximum limits established by the regulatory agencies. The substances prohibited are:
1. Any liquid or vapor having a temperature higher than one hundred fifty degrees Fahrenheit (150°F) (65°C).
2. Any waters or wastes containing toxic or poisonous materials; or oils, whether emulsified or not, in excess of one hundred milligrams per liter (100 mg/l) or containing substances which may solidify or become viscous at temperatures between thirty two degrees Fahrenheit (32°F) (0°C) and one hundred fifty degrees Fahrenheit (150°F) (65°C).
3. Any garbage of any kind. The installation of a garbage grinder on any line discharging to a public sewer is prohibited 1 .
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 or similar objectionable or toxic substances; or wastes exerting an excessive chlorine requirement, to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the village board of trustees for such materials.
6. Any waters or wastes containing phenols or other taste or odor producing substances, in such concentrations exceeding limits which may be established by the village board of trustees as necessary after treatment of the composite sewage, to meet the requirements of the state, federal or other public agencies of jurisdiction for such discharge to the receiving waters.
7. Any radioactive wastes or isotopes of such half life or concentration as may exceed limits established by the village board of trustees in compliance with applicable state or federal regulations.
8. Any waters or wastes having a pH in excess of nine and five-tenths (9.5).
9. The admission into the sewers of any waters or wastes having: a) BOD5 greater than seventy (70) parts per million by weight; or b) containing more than one hundred twenty (120) parts per million by weight of suspended solids; or c) containing any quantity of substances having the characteristics described heretofore in this section; or d) having an average daily flow greater than two percent (2%) of the average daily sewage flow of the village, shall be subject to the review and the approval of the board of trustees of the village. Where necessary in the opinion of the board of trustees, the owner shall provide, at his expense, such preliminary treatment as may be necessary to: a) reduce the BOD5 to seventy (70) parts per million and the suspended solids to one hundred twenty (120) parts per million by weight; or b) reduce objectionable characteristics or constituents to within the maximum limits provided for in this section; or c) control the quantities and rates of discharge of such waters or wastes. Construction of such facilities shall not be commenced until plans therefor have been submitted to and the written approval of such plans has been obtained from the village board of trustees.
10. Any mercury or any of its compounds in excess of 0.0005 mg/l as Hg at any time except as permitted by the board of trustees in compliance with applicable state and federal regulations.
11. Any cyanide in excess of 0.025 mg/l at any time except as permitted by the board of trustees in compliance with applicable state and federal regulations.
12. Materials which exert or cause:
(a) Unusual concentrations of inert suspended solids (such as, but not limited to, fuller's 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 BOD, chemical oxygen demand or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works;
(d) Unusual volume of flow or concentrations of wastes constituting "slugs" as defined herein.
13. 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 such degree that the sewage treatment plant effluent cannot meet the requirements of agencies having jurisdiction over discharge to the receiving waters.
(E) 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 subsection (D) of this section and/or which are in violation of the standards for pretreatment provided in chapter 1, EPA rules and regulations, subchapter D, water programs part 128 - pretreatment standards, "Federal Register" volume 38, no. 215, Thursday, November 8, 1973, and any amendments thereto, and which, in the judgment of the superintendent of public works, may have a deleterious effect upon the sewage works, processes, equipment or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the superintendent of public works 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 the added costs of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of subsection 7-6-14(C) of this chapter.
If the superintendent of public works 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 superintendent of public works and subject to the requirements of all applicable codes, ordinances and laws. (Ord. 9-16-85)
(F) The village is authorized to assure that impacts on water quality from discharges form combined sewer overflows that receive nondomestic waste are minimized. The village is further authorized to determine which nondomestic wastewater discharges are tributary to any combined sewer overflows and the village may, at its discretion, review and modify these provisions to control pollutants sourced from said combined sewer overflows. (Ord. 05-05-16-01, 5-16-2005)
