§ 52.13 USE OF THE PUBLIC SEWERS.
   (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.
   (B)   Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as combined sewers or 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, combined sewer or natural outlet.
   (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 gasses 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 properties capable of causing damage or hazard to structures, equipment and personnel of the sewage works.
      (4)   Solid or viscuous 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 hole or ground by garbage grinders.
      (5)   Any water, waste, sewage, discharge or wastewater containing a concentration of 1000 mg/l COD or greater. As used in this section, “COD” denotes a bulk parameter that measures the oxygen consuming capacity of organic and inorganic matter present in water or wastewater.
      (6)   Any water, waste, sewage, discharge or wastewater containing which exhibits a ratio of BOD (as defined in § 52.02) to COD of less than 0.3.
   (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 village that such wastes can harm either the sewers, sewage treatment process, or equipment, have an adverse effect on the receiving stream, or constitute a nuisance. In forming his opinion as to the acceptability of these waters, 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 and maximum limits established by regulatory agencies. The substances prohibited are:
      (1)   Any liquid or vapor having a temperature higher than 150º Fahrenheit, (65º C);
      (2)   Any waters or wastes containing toxic or poisonous materials; or oils, whether emulsified or not, in excess of 100 mg/1 or containing substances which may solidify or become viscuous at temperatures between 32º and 150º Fahrenheit, (0º and 65º C);
      (3)   Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped, with a motor of three-fourths horsepower (0.76 hp metric) or greater shall be subject to review and approval of the village;
      (4)   Any waters or wastes containing strong acid, iron pickling wastes or concentrated plating solution 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 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 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 into the receiving waters;
      (7)   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;
      (8)   Any wastes or waters have a pH in excess of 9.5;
      (9)   Any mercury or any of its compounds in excess of 0.05 mg/1 as Hg at any time except as permitted by the village in compliance with applicable state and federal regulations;
      (10)   Any cyanide in excess of 0.025 mg/1 at any time except as permitted by the village in compliance with state and federal regulations; and
      (11)   Materials which exert or cause:
         (a)   Unusual concentrations of inert suspended solids (such as, but not limited to filler 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.
      (12)   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;
      (13) Any water or wastewater containing more than 250 mg/l total surfactants, where total surfactants are measured as the sum of (i) anionic surfactants as MBAS, (ii) nonionic surfactants as CTAS, and (iii) cationic surfactants measured as the difference between sublation residue and MBAS and CTAS values;
      (14)   Any water or wastewater containing more than 300 mg/l BOD;
      (15)   Any water or wastewater containing more than 350 mg/l in total of suspended solids. As used in this section, “suspended solids” shall have the meaning set forth therefor in § 51.01; and
      (16)   Any water or wastewater containing any substance or material or any concentration of any substance or material, where the discharge of such substance, material or concentration thereof into any public sewer or wastewater treatment system is prohibited by regulations or rules promulgated or adopted by the Illinois Environmental Protection Agency or the United States Environmental Protection Agency.
   (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 division (D) 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:
      (1)   Reject the wastes;
      (2)   Require pretreatment to an accept- able 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 division (B) of this section.
   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.
   (F)   Grease, oil, and sand interceptors shall be provided when, in the opinion of the village they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand, or other harmful ingredients; except that such inter-ceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the village, and shall be located as to be readily and easily accessible for cleaning and inspection.
   (G)   Where preliminary treatment or flow-equalizing facilities are provided, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense.
   (H)   Each industry shall be required to install a control manhole and, when required by the village, 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 accessibly and safely located, and shall be constructed in accordance with plans 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.
   (I)   The owner of any property serviced by a building sewer carrying industrial wastes shall provide laboratory measurements, tests and analysis of waters and wastes to illustrate 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 analysis to be performed by the owner shall be 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 a manner as prescribed by the village. The owner shall bear the expense of all measurement, analysis and reporting required by the village. At such times as deemed necessary the village reserves the right to take measurements and samples for analysis by an outside laboratory service.
   (J)   All measurements, tests and analysis 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 IEPA Division of Laboratories Manual of Laboratory Methods, and shall be determined at the control manhole provided, 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. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property. The particular analysis involved will determine whether a 24 hour composite of all outfalls of a premise is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analysis are obtained from 24 hour composites of all outfalls, whereas pH's are determined from periodic grab samples.
   (K)   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 for treatment, subject to payment therefore, in accordance with § 52.10, hereof, by the industrial concern provided such payments are in accordance with federal and state guidelines for user charge system.
   (L)   (1)   In order to ensure that commercial and industrial users of the village's sanitary sewer system adhere to and comply with the restrictions and prohibitions set forth in this section pertaining to prohibited discharges into the village's sanitary sewer system, and to facilitate the village's investigation of apparent or suspected violations thereof, all such existing commercial and industrial users, and all such users occupying facilities located on any non-residentially zoned property within the village or in areas receiving sewer service from the village, shall be required to annually complete and submit a discharge questionnaire (reference Appendix A, Ordinance 92-01, passed 9-5-01), provided, however, that upon the completion of and submission to the village of an initial discharge questionnaire commercial and industrial users and all such users occupying facilities located on any non- residentially zoned property within the village or in areas receiving sewer service from the village may thereafter comply with the provisions of this division by annually submitting to the village a notarized statement of any and all changes in the information requested by the discharge questionnaire, or a notarized statement that the information originally submitted in response to the initial discharge questionnaire remains true, complete and correct in all respects. Completed discharge questionnaires, statements of changes in information submitted in response to a previously filed discharge questionnaire, or statements affirming the continuing truth, completeness and correctness of information submitted in response to a previously filed discharge questionnaire, as the case may be, shall be filed by existing commercial and industrial users and all such users occupying facilities located on any non-residentially zoned property within the village or in areas receiving sewer service from the village with the Village Department of Public Works not later than January 31 of each calendar year, and all new commercial and industrial users and all such users occupying facilities located on any non-residentially zoned property within the village or in areas receiving sewer service from the village seeking to establish a new account for sanitary sewer service from the village or to establish a new connection to the village's sanitary system shall file an initial completed discharge questionnaire with the village as a condition to the establishment of such new sanitary sewer service account or connection to the village's sanitary sewer system.
      (2)   Any commercial or industrial user of the village's sanitary sewer system or any such users occupying facilities located on any non-residentially zoned property within the village or in areas receiving sewer service from the village that fail to complete and submit to the village an initial discharge questionnaire, an annual statement of changes in information submitted in response to a previously filed discharge questionnaire or an annual statement affirming the continuing truth, completeness and correctness of information submitted in response to a previously filed discharge questionnaire shall be in violation of the provisions of this division (1) and shall be subject to all of the applicable penalties therefor, including but expressly not limited to the revocation of all permits and approvals previously granted to the commercial or industrial user in question for the discharge of sewage or wastewater into the village sanitary sewer system.
