A. No person shall discharge, or cause to be discharged, any storm water, surface water, ground water, roof runoff, subsurface drainage, uncontaminated cooling water, or unpolluted industrial process waters to any public sanitary sewer.
B. Storm water and all other unpolluted drainage shall be discharged to storm sewers or to a natural outlet approved by the superintendent. Industrial cooling water or unpolluted process waters may be discharged upon approval of the superintendent, to a storm sewer or natural outlet.
C. No person shall discharge or cause to be discharged to a public sanitary sewer the following described substances, materials, waters, or wastes if it appears likely in the opinion of the superintendent that such waters or 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 will give consideration to such factors as the quantities of such waters or wastes in relation to flows and velocities in the sewers, materials or construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, and maximum limits established by regulatory agencies. The substances prohibited are:
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 the 5.5 or higher than 9.5, or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the sewerage works.
4. Solid or viscous substance in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewerage system such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, woods, whole blood, paunch manure, hair and fleshing, entrails and paper dishes, cups, and milk containers either whole or ground by garbage grinders.
5. Any liquid or vapor having a temperature higher than one hundred fifty degrees Fahrenheit (150°F).
6. 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 and one hundred fifty degrees Fahrenheit (32 and 150°F) (0 and 65°C).
7. 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 superintendent.
8. Any waters or wastes containing strong acid, iron pickling wastes, or concentrated plating solutions whether neutralized or not.
9. 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.
10. Any waters or wastes having a pH in excess of 9.5.
11. Any water or wastes containing substances exceeding the maximum concentrations of pollutants as set forth in the following table:

12. 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.
13. Any mercury or any of its compounds in excess of 0.005 mg/l as Hg at any time except as permitted by the village in compliance with applicable state and federal regulations.
14. Any cyanide in excess of 0.025 mg/l at any time except as permitted by the village in compliance with applicable state and federal regulations.
15. 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 flow or concentrations of waters constituting "slugs" as defined herein.
16. 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 wastewater treatment plant effluent cannot meet the requirements of agencies having jurisdiction over discharge to the receiving waters.
D. If any water or wastes are discharged, or are proposed to be discharged to the public sanitary sewers, which waters contain the substances or possess the characteristics enumerated in subsection C 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 403 - "General Pretreatment Regulations For Existing And New Sources Of Pollution" published in federal register volume 43, no. 123 Monday, June 26, 1978, and any amendments thereto, and continuously in satisfactory and effective operation by the owner at his expense.
E. Each industry shall be required to install a control manhole, and when required by the county, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling, and measurement of the wastes. Such manhole, when required, shall be accessible and safely located, and shall be constructed in accordance with plans and approved by the village. The manhole shall be installed by the owner at his expense, and shall be maintained by him so as to be safe and accessible at all times.
F. The owner of any property serviced by a building sewer carrying industrial wastes shall provide laboratory measurements, tests, and analysis of waters and waste to demonstrate compliance with this chapter and any special conditions for discharge established by the village or regulatory agencies having jurisdiction over the discharge. The number, type, and frequency of laboratory analyses to be performed by the owner shall be as stipulated by the village, but no less than once per year. The industry must supply a complete analysis of the constituents of the wastewater discharge to assure that compliance with the federal, state, and local standards are being met. The owner shall report the results of measurements and laboratory analysis to the village at such times and in such manner as prescribed by the village. The owner shall bear the expense of all measurements, analyses, and reporting required by the village. At such times as deemed necessary, the village reserves the right to take measurements and samples for analysis.
G. All measurements, tests and analyses of the characteristics of waters 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 Water And Wastewater", published by the American Public Health Association and "USEPA Guidelines Establishing Test Procedures For Analysis Of Pollutants" pursuant to 40 CFR part 136 and shall be determined at the control manhole, using suitable samples taken at such 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. Sampling shall be carried out by the customary accepted methods to reflect the effect of constituents upon the sewerage works and to determine the existence of hazards to life, limb, and property. (The particular analyses involved will determine whether a 24 hour composite sample or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from 24 hour composite samples, whereas pHs are determined from period grab samples.)
H. 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 permitted by the village for treatment subject to payment therefor by the industrial concern, provided such payments are in accordance with the applicable ordinance governing sewer user service charges, and provided further, that such situation may be governed by any other agreement between the village and the North Shore sanitary district.
