(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 sanitary sewer.
(B) Storm water 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 appropriate state agency. Industrial cooling water or unpolluted process waters may be discharged upon approval of the Superintendent and the State Department of Natural Resources, to a storm sewer or natural outlet.
(C) Except as hereinafter provided by specific limits, no person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
(1) BOD5 in excess of 300 mg/1;
(2) COD in excess of 450 mg/1;
(3) Chlorine demand in excess of 15 mg/1;
(4) Color, as from but not limited to dyes, inks and vegetable tanning solutions, shall be controlled to prevent light absorbancy which would interfere with treatment plant processes or that prevent analytical determinations;
(5) Explosive liquid, solid or gas, gasoline, benzene, naptha, fuel oil or other flammable shall not be admitted;
(6) Garbage not properly shredded (no particle size greater than one-half inch) shall not be allowed;
(7) Grease, oils, wax, fat, whether emulsified or not, in excess of 50 mg/1; or other substance which may solidify or become viscous at temperatures between 32°F and 150°F shall not be admitted to the sanitary sewer;
(8) (a) Industrial wastes in concentrations above those listed below shall not be allowed to enter sanitary sewers:
Cd CN Cr+6 Cr Total Cu FE Ni
Pb Phenols Zn
(Limitations set forth by appropriate state agencies to comply with federal guidelines for protection of treatment plan and receiving water course)
(b) Or any other metallic compounds in sufficient quantity to impair the operation of the sewage treatment processes.
(9) Inert suspended solids (such as but not limited to Fullers earth, lime slurries and lime residues) or of dissolved solids (such as but not limited to sodium chloride and sodium sulfate) in unusual
concentrations shall not be allowed;
(10) Insoluble, solid or viscous substances such as but not limited to ashes, cinders, sand, mud, straw, shavings, metal, glass, tar, feathers, plastics, wood, hair, fleshings and the like, shall not be admitted to sanitary sewers;
(11) Noxious or malodorous gas, such as but not limited to hydrogen sulfide, sulphur dioxide or oxides of nitrogen and other substances capable of producing a public nuisance shall not be allowed;
(12) pH less than 5.5 and greater than 9.5 shall not be allowed;
(13) Radioactive wastes or isotopes of such half-life or concentration which may exceed limits established by applicable state and federal regulations shall not be allowed;
(14) Suspended solids in excess of 350 mg/1;
(15) Temperature of wastes less than 32°F and greater than 150°F shall not be allowed; and
(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 sewage treatment plant effluent cannot meet the requirements of the NPDES permit having jurisdiction over the discharge to the receiving waters.
(D) (1) 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 (C) above, and which in the judgment of the Superintendent, may have a deleterious effect upon the sewage works, or which otherwise create a hazard to life or constitute a public nuisance, the village may:
(a) Reject the wastes;
(b) Require pre-treatment 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 cost of handling and treating the wastes not covered by existing sewer charges, under the provisions of division (J) below.
(2) If the village permits the pre-treatment 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. All pre-treatment shall be done in accordance with federal pre-treatment standard (40 C.F.R. part 403).
(E) Grease, oil and sand interceptors shall be provided, when, in the opinion of the Superintendent 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 interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Superintendent, and shall be located as to be readily and easily accessible for cleaning and inspection.
(F) Where preliminary treatment or flow equalizing 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.
(G) 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 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.
(H) (1) All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this subchapter shall be determined in accordance with the most recent edition of Standard Methods for the Examination of Water and Sewage, and shall be determined at the control manhole provided for, 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.
(2) Samplings shall be carried out by customarily accepted methods pursuant to Guidelines for Established Test Procedures for Analyses of Pollutants to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property. The particular analyses involved will determine whether a 24-hour composite of all outfalls of a premise is appropriate or whether grab sample or samples should be taken.
(I) 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 therefrom, by the industrial concern in accordance with the rate ordinance of the village.
(J) When an industrial user, as defined in the Federal Register (40 C.F.R. § 35.905), begins discharging to treatment works constructed by an E.P.A. federal grant, the village shall develop and implement an industrial cost recovering system in accordance with federal regulations (40 C.F.R. § 35.928).
