(a) Prohibition of Unpolluted Water. No person shall discharge or cause to be discharged, either directly or indirectly, any storm water, surface water, ground water, roof run- off, subsurface drainage, cooling water, or unpolluted industrial process waters to any sanitary sewer.
(1) Any such connections made either before or after the effective date of this chapter shall be considered illegal and shall be subject to immediate removal by the owner of the premises so connected and at such owner's expense.
(2) Sub-foundation building drains connected to sanitary sewers before the effective date of this chapter will not be required to be removed unless it is established by the Village that such connection is detrimental to the satisfactory operation of the sewage works and that such removal is cost- effective. Any such connections made after the effective date of this chapter shall be prohibited and shall be considered illegal.
(3) Should the owner of such an illegally connected premises fail to remove the connection within ninety (90) days after official notice to do so, the Village shall cause the connection to be removed and the cost thereof shall be billed to the owner of the premises.
(b) Illegal Discharges to Natural Outlet or Storm Sewer. No person shall discharge, or cause to be discharged, to any natural outlet or storm sewer any sanitary, industrial, or other polluted wastewater.
(c) Allowable Discharge of Unpolluted Water. Storm water and all other unpolluted drainage, such as from air conditioning, swimming pools, etc. shall be discharged into such sewers as are specifically designed and designated as storm sewers or to a natural outlet approved by the Administrator. Industrial cooling water or unpolluted wastewater may be discharged, on approval of the Village Engineer, to a storm sewer or natural outlet. If such waters are polluted with insoluble oils or grease or suspended solids, they shall be treated for removal of the pollutants, and the clear water discharged as specified.
(d) Trucked or Hauled Wastes. No person shall access the sewer system or WWTP for any activity including discharge of hauled septic or industrial wastes. Any removal of manhole lids, or other access to the sewer system for the purpose of discharging wastes, shall be considered a violation and shall be subject to enforcement action including fines and penalties allowed under this chapter.
(e) General Discharge Prohibition.
(1) As to any waters or wastes which are discharged, or are proposed to be discharged, which contain compatible or incompatible pollutants other than sanitary sewage and which may have a deleterious effect upon the sewage works, processes, equipment, or receiving waters, including violation of applicable water quality standards, or which otherwise create a hazard to life or constitute a public nuisance, the Village shall:
A. Reject the discharge of such waters or wastes;
B. Require pretreatment of quantities and establish rates of discharge to the public sewers; and/or
C. Require payment to cover the added cost of handling, treating and disposing of the wastes.
(2) Provided however, that no person, firm or corporation shall contribute, discharge, or cause to be discharged, directly or indirectly any of the following described substances into the Village sewage works:
A. Any liquids, solids, or gases which by reason of their nature or quality are, or may be, sufficient, either alone or by interaction, to cause fire or explosion, including but not limited to, waste streams with a closed cup flash point of less than one hundred forty (140) degrees Fahrenheit or sixty (60) degrees centigrade using the test method specified in 40 CFR 261.21, or be injurious in any other way to persons or the operation of the sewage works;

E. Any noxious or malodorous liquids, gases, or solids which either singly or by interaction are capable of creating a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for their maintenance and repair;
F. Any substance which may cause the wastewater treatment plant effluent or treatment residues, sludges, or scums, to be unsuitable for reclamation and reuse or which interferes with the reclamation process. In no case shall a substance discharged to the sewage works cause noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act, or any criteria, guidelines, or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substance Control Act, Resource Conservation Recovery Act, or State standards applicable to the sludge management method being used;
G. Any substance which will cause the wastewater treatment plant to violate its NPDES and or disposal System Permits;
H. Any substance with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions;
I. Any wastewater having a temperature which will inhibit biological activity in the wastewater treatment plant resulting in interference, but in no case wastewater with a temperature at the introduction into sewage works which exceeds forty (40) degrees Centigrade (one hundred four (104) degrees Fahrenheit);
J. Any slug as defined in Section 925.02;
K. Any wastewater containing any radioactive wastes or isotopes of such half life or concentration that exceed limits established by the Village in compliance with applicable State and Federal regulations;
L. Any wastewater which causes a hazard to human life or which creates a public nuisance;
M. Wastewater containing more than fifty milligrams per liter of petroleum oil, non-biodegradable cutting oils, products of mineral oil origin, or floatable oils, fat, wax, or grease (Freon soluble) or wastewater containing such materials in sufficient amounts to pass through or cause interference in the sewage works;
N. Wastewater containing oil or grease or other substances which will solidify or become discernibly viscous at temperatures between thirty (30) and one hundred fifty (150) degrees Fahrenheit;
O. Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths horsepower (HP) or greater shall be subject to the review and approval of the Village Engineer; and/or
P. Any unpolluted water including, but not limited to non-contact cooling water, which is used to dilute process wastewater, or in any other way attempts to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with a pretreatment standard or requirement (40 CFR 403.6 (d)), except such water may be discharged to a sewer which is designated to carry storm water.
(f) Limitations on Wastewater Strength. The National Categorical Pretreatment Standards, as promulgated by the USEPA pursuant to the Act, which are hereby adopted and incorporated herein by the reference shall be met by all users of regulated industrial categories.
