(A)   No person shall discharge or cause to be discharged the substances, materials, waters, or wastes described in division (B) below if it appears likely in the opinion of the Superintendent that such wastes can harm either the sewers, sewage treatment process, or equipment have an adverse effect on the receiving stream, or otherwise endanger life, limb, public property, or constitute a nuisance. In forming her or his opinion as to the acceptability of these wastes, the Superintendent 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 other pertinent factors.
   (B)   The substances prohibited are:
      (1)   Any liquid or vapor having a temperature higher than 150°F;
      (2)   Any water or waste containing fats, wax, grease, or oils, whether emulsified or not, in excess of 100 milligrams per liter or containing substances which may solidify or become viscous at temperatures between 32 and 150°F;
      (3)   Any garbage that has not become properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths horsepower (0.76-hour power metric) or greater shall be subject to the review and approval of the Superintendent;
      (4)   Any waters or wastes containing strong acid, iron pickling wastes, or concentrated plating solutions, whether neutralized or not;
      (5)   Any waters or wastes containing iron, chromium, copper, zinc, and similar objectionable or toxic substances, or wastes exerting any 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 Superintendent for such materials;
      (6)   Any waters or wastes containing phenols or other taste-producing or odor-producing substances, in such concentrations exceeding limits which may be established by the Superintendent 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;
      (7)   Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Superintendent in compliance with applicable state or federal regulations;
      (8)   Any waters or wastes having a pH in excess of 9.5;
      (9)   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, chemical oxygen found, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works; or
         (d)   Unusual volume of flow or concentration of wastes constituting “slugs” as defined in this chapter.
      (10)   Water or wastes containing substances which are not amendable 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 other agencies having jurisdiction over discharge to the receiving waters; and
      (11)   Industrial wastes, as defined in this chapter, shall not be discharged to public sewers. Industrial wastes may be discharged to storm sewers or natural outlet only when adequately treated to comply with required standards established by the state agency responsible.
         (a)   In the event the village, after February 3, 1975, agrees to accept industrial waste, the village shall provide that the industry complies with the Industrial Cost Recovery provisions of the U.S. Environmental Protection Agency, as cited in the February 11, 1974, Federal Register, Vol. 39, No. 29, § 35.928, which is summarized as follows:
            1.   The cost recovery period shall be 30 years starting January 1, 1975;
            2.   During each of the 30 years, each industrial user of the treatment works shall pay its share of the total amount of the $589,600 federal grant and any grant amendment awarded pursuant to this division (B)(11)(a), divided by the recovery period (30 years);
            3.   Payments shall be made by the industrial users no less often than annually. The first payment by an industrial user shall be made no later than one year after such user begins use of the treatment works;
            4.   An industrial user’s share shall be based on such factors as strength, volume, and delivery flow to insure a proportional distribution of the grant assistance allocable to industrial use to all industrial users of the treatment works. As a minimum, an industry’s share shall be proportional to its flow in relation to treatment works flow capacity;
            5.   If there is a substantial change in the strength, volume, or delivery flow rate characteristics introduced into the treatment works by an industrial user, such user’s share shall be adjusted accordingly;
            6.   If there is an expansion or upgrading of the treatment works, each existing industrial user’s share shall be adjusted accordingly;
            7.   An industrial user’s share shall include only that portion of the grant assistance allocable to its use or to capacity firmly committed for its use; and
            8.   An industrial user’s share shall not include an interest component.
         (b)   In the event an industrial waste agreement is approved by the village and moneys are received under conditions set forth in this division (B)(11), the disposition of those receipts shall be in accordance with U.S. Environmental Protection Agency regulations, as cited in the February 11, 1974, Federal Register, Vol. 39, No. 29, § 35.928-2, retained amounts, and stated below:
            1.   The grantee shall retain 50% of the amount recovered from industrial users. The remainder, together with any interest earned thereon, shall be returned to the U.S. Treasury on an annual basis;
            2.   A minimum of 80% of the retained amounts, together with interest earned thereon, shall be used solely for the eligible costs of the expansion or reconstruction of treatment works associated with the project and necessary to meet the requirements of the act. The grantee shall obtain the written approval of the regional administrator prior to commitment of the retained amount for any expansion and reconstruction. The remainder of the retained amounts may be used as the grantee sees fit; and
            3.   Pending use, the grantee shall invest the retained amounts for reconstruction and expansion in obligations of the U.S. Government, or obligations guaranteed as to principal and interest by the U.S. Government or any agency thereof; or shall deposit such amounts in accounts fully collateralized by obligations of the U.S. Government or by obligations fully guaranteed as to principal and interest by the U.S. Government or any agency thereof.
