A. Stormwater And Surface Water:
1. 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. 1023, 6-15-1992)
2. 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 village. Industrial cooling water or unpolluted process waters may be discharged, on approval of the village, to a storm sewer or natural outlet. (Ord. 1023, 6-15-1992; amd. 2011 Code)
B. Prohibited Discharges:
1. No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
a. Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid, or gas.
b. 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.
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 sewage works.
d. 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. (Ord. 1023, 6-15-1992)
2. It shall be unlawful for any person, firm or corporation to connect or cause to be connected any drain carrying, or constructed to carry, the wastes from any toilet, sink, basement, septic tank, cesspool, industrial waste or any fixture or device discharging polluting substances, to any stormwater drain within the village. Any person violating this subsection B2 shall be fined as provided in section 1-4B-1 of this code. (1983 Code § 8-5-9; amd. 2011 Code)
C. Restricted Discharges:
1. 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 village, 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 its opinion as to the acceptability of these wastes, the village will 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 regulatory agencies. The substances prohibited are:
a. Any liquid or vapor having a temperature higher than one hundred fifty degrees Fahrenheit (150°F) (65°C).
b. 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 (32) and one hundred fifty degrees Fahrenheit (150°F) (0 and 65°C).
c. Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths (3/4) horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the village.
d. Any waters or wastes containing strong acid, iron pickling wastes, or concentrated plating solutions, whether neutralized or not.
e. Any waters or wastes containing iron, chromium, copper, zinc, or similar objectionable or toxic substances, or waste 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 for such materials.
f. 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 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.
g. Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the village in compliance with applicable state or federal regulations.
h. Any waters or wastes having a pH in excess of 9.5.
i. Any mercury or any of its compounds in excess of 0.0005 milligram per liter as Hg at any time except as permitted by the village in compliance with applicable state and federal regulations.
j. Any cyanide in excess of 0.025 milligram per liter at any time except as permitted by the village in compliance with applicable state and federal regulations.
k. Materials which exert or cause:
(1) Unusual concentration 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).
(2) Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions).
(3) Unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.
(4) Unusual volume of flow or concentrations of wastes constituting "slugs" as defined in section 9-3-1 of this chapter.
l. Waters or wastes containing substances which are not amendable to treatment or reduction by the sewage treatment process employed or are amendable 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.
2. 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 C1 of this section, and/or which are in violation of the standards for pretreatment provided in 40 CFR 403, June 26, 1978, and any amendments thereto, and which, in the judgment of the village, 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 village 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 the added costs of handling and treating the wastes not covered by existing taxes or sewer charges, under the provisions of section 9-3-7-6 of this chapter.
3. If the village 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 village and subject to the requirements of all applicable codes, ordinances, and laws. (Ord. 1023, 6-15-1992)
