(7) 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 wastewater, to meet the requirements of the state, federal, or other public agencies of jurisdiction for such discharge to the receiving waters;
(8) 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;
(9) Any wastes or waters having a pH in excess of 9.0;
(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 village 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 village 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, Fullers 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, total suspended solids, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the wastewater treatment system; and
(d) Unusual volume of flow or concentrations of wastes constituting slugs as defined herein.
(13) Waters or wastes containing substances which are not amendable to treatment or reduction by the wastewater treatment processes employed, or are amendable to treatment only to such degree that the wastewater treatment system effluent cannot meet the requirements of agencies having jurisdiction over discharge to the receiving waters.
(H) (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 of this chapter, and/or which are in violation of the standards for pretreatment provided in the Federal Clean Water Act and any amendments thereto, and which in the judgment of the village may have a deleterious effect upon the wastewater treatment system, 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
(d) Require payment to cover the added costs of handling and treating the wastes not covered by existing taxes or wastewater charges, under the provisions of this chapter.
(2) If the village permits the pretreatment or equalization of waste flows, the design and installation of the system 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.
(I) Grease, oil, and sand interceptors shall be provided when, in the opinion of the village, they are necessary for the proper handling or treatment of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand, or other harmful ingredients. 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.
(J) Where preliminary treatment or flow-equalizing facilities or greases, oil, and sand interceptors are provided, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.
(K) 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 accessible and safely located, and shall be constructed in accordance with plans approved by the village. The manhole shall be installed and operated by the owner at his or her expense, and shall be maintained by him or her so as to be operational, safe, and accessible at all times.
(L) (1) The owner of any property serviced by a building sewer carrying industrial wastes shall provide laboratory measurements, tests, and analyses of waters and wastes to comply with this chapter and any special conditions for discharge established by the village or regulatory agencies having jurisdiction over the discharge.
(2) 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 analyses 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 analyses 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 analyses by an outside laboratory service.
(M) (1) All sampling and analysis of the characteristics of waters and wastes to which reference is made in this chapter shall be performed in accordance with the techniques prescribed in the current Environmental Protection Agency. Sampling and analytical techniques may be further specified by the village in order to assess the effect of wastewater constituents upon the wastewater treatment system and to determine the existence of hazards to life, limb, and property. Where the current EPA requirements do not contain sampling and analytical techniques for the pollutant in question, sampling and analysis must be performed using procedures approved by the village.
(2) Samples shall be taken at the control manhole. Certain analyses (such as, pH, DO, conductivity, and the like) may be directly performed upon grab samples taken periodically at the control manhole while BOD and total suspended solids analyses are normally performed upon 24-hour composite samples taken at the control manhole. If a control manhole does not exist, then sampling and analysis will be performed at the manhole immediately downstream from the point where the building sewer connects to the public sewer, or at another point acceptable to the village, including the user’s buildings and grounds.
(N) No statement contained in this chapter 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 therefor by the industrial concern, provided such payments are in accordance with federal and state guidelines for wastewater charge system.
