(2) 
Any wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction or in combination with other wastes, to injure or interfere with any waste treatment process, constitute a danger to humans, flora or fauna, create a public nuisance, or create any hazard in the receiving waters of the wastewater treatment plant;

Unpolluted waters. Unpolluted waters, including stormwater, groundwater, rainwater, street drainage, roof runoff or subsurface drainage, cooling water, process water or blowdown from cooling towers or evaporative coolers, shall not be discharged into the local system without prior approval of the Village. Such approval shall be granted only when no reasonable alternative method of disposal is available and upon payment of applicable charges and fees and compliance with conditions as required by the Village and Commission.

A. 
Limitations related to treatment plant influent. Discharge to the local system of the following described substances, materials, waters or waste shall be limited to the following concentrations or quantities, provided that such concentrations or quantities will not harm the local system, regional system, wastewater treatment plant, wastewater treatment process or equipment; will not have an adverse effect on the receiving stream; will not have an adverse effect on the sludge management program; will not endanger persons or property; will not cause air pollution or other detrimental environmental effects; and will not constitute a nuisance:
(1) 
Liquid having a temperature higher than 65° C. (149° F.) or any wastewater having a temperature which will inhibit biological activity in the wastewater treatment plant, thereby resulting in interference; notwithstanding the foregoing, in no case shall wastewater be discharged having a temperature that causes the influent to the wastewater treatment plant to exceed 40° C. (104° F.), unless the Commission Engineer certifies that the wastewater treatment plant is designed to accommodate such temperature;
(2) 
Wax, grease, oil, plastic or any other substance that solidifies or becomes discernibly viscous;
(3) 
Radioactive wastes which, alone or with other wastes, result in releases greater than those specified by current United States Bureau of Standards handbooks, or which violate rules or regulations of any applicable regulatory agency;
(4) 
Wastewater containing more than 50 milligrams per liter of petroleum oil, nonbiodegradable cutting oils, or products of mineral oil origin;
(5) 
Wastewater containing more than 300 mg/l of oil or grease of animal or vegetable origin;
(6) 
Wastewater which in concentration of any given constituent or in quantity of flow exceeds for any period of duration longer than 15 minutes more than five times the average twenty-four-hour concentration or flows during normal operation;
(7) 
Wastewater which contains in excess of any of the following constituents in a twenty-four-hour flow proportionate sample made up of an aggregate of the total discharge from all of the outfalls of the industrial user:
1.0 mg/l aluminum
0.02 mg/l cadmium
0.1 mg/l hexavalent chromium
0.5 mg/l total chromium
0.2 mg/l copper
2.0 mg/l lead
0.02 mg/l mercury
0.3 mg/l selenium
0.04 mg/l silver
2.0 mg/l nickel
1.0 mg/l nickel
0.35 mg/l cyanide
(a) 
The Village shall cooperate with the Commission Engineer in changing the requirements established in this chapter above if necessary to meet the objectives of this chapter or a condition of the Commission's WPDES permit;
(b) 
Samples shall be collected over the period of discharge if the discharge is less than 24 hours in duration;
(8) 
Industrial discharges exceeding applicable National Categorical Pretreatment Standards or state standards;
(9) 
Any substance with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solution;
(10) 
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; or
(11) 
Any discharge prohibited or limited as determined by the Commission to be necessary to meet the objectives of this chapter or the conditions of its WPDES permit.
B. 
Limitations related to treatment plant effluent.
(1) 
Specific. No person shall discharge any wastewater to the local system which, in combination with other discharges, results in either:
(a) 
The wastewater treatment plant effluent having concentrations exceeding the following limits: 0.1 mg/l total phenols or 0.002 mg/l polychlorinated biphenols (PCB's); or
(b) 
The wastewater treatment plant's digested sludge exceeding a PCB concentration of 10.0 ppm on a dry-weight basis.
(2) 
General. No person shall cause or permit a discharge into the local system that would cause, or significantly contribute to, either directly or indirectly, a violation of the conditions of the Commission's WPDES permit and any modification or reissuance thereof.
C. 
Limitations superseded. Upon promulgation of National Categorical Pretreatment Standards for a particular industrial user subcategory, the federal standards (if more stringent than the limitations imposed under these regulations) shall immediately supersede the limitations imposed under these regulations, and such industrial user shall comply with said federal standards upon notification by the Commission of the applicable requirements under 40 CFR 403.12, as may be amended from time to time.
Dilution of an industrial discharge for purposes of reducing the pollutant characteristics or concentrations to below the limitations established in this article, or below other applicable pretreatment standards, is prohibited.
Any person who accidentally discharges into the local system wastes or wastewater prohibited under these regulations shall immediately report such a discharge to the Village and the Commission. Such report shall describe the location, time and volume of the discharge and the type of waste or wastewater discharged. Within 15 days of such discharge, a detailed written statement describing the cause of the discharge and the measures taken to prevent a future occurrence shall be submitted to the Village and Commission. Such reporting shall not relieve the person causing the accidental discharge from any penalties imposed by this chapter or Commission Regulations. Where the Village or Commission deems necessary, industrial users shall provide facilities to prevent accidental discharges or spills of wastes or wastewaters prohibited under these regulations.
If any waters or wastes are discharged or are proposed to be discharged to the local system in excess of those limitations enumerated herein, the Village, following consultation with the Commission, shall:
A. 
Reject the wastes;
B. 
Require pretreatment;
C. 
Control the quantities and rates of discharge; and/or
D. 
Recover the increased costs of handling and treating such wastes.
Industrial users shall comply with the provisions of this chapter and Commission Regulations, as may be amended from time to time, and any additional conditions related to a specific industrial user as determined by the Village and Commission. Industrial users may be required to pretreat their wastewater when necessary to protect the wastewater facilities or prevent discharge of incompatible pollutants. Construction, operation and maintenance of pretreatment facilities shall be at the expense of the user. Pretreatment facilities shall be operated by qualified personnel holding a Grade 1 certificate in appropriate subgrade as issued by the DNR.
The Village shall require such traps as are deemed necessary by the Commission, in its sole opinion, for the proper handling of liquid wastes containing floatable oil or grease in amounts in excess of the limitations as specified in this article, or any flammable wastes, sand, or other harmful ingredients. However, such traps shall not be required for private living quarters or dwelling units. All such traps shall be of a type and capacity approved by the Commission and shall be located as to be readily and easily accessible for cleaning and inspection. In maintaining these traps, the Village or other owner shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal. Such records shall be submitted to the Village and Commission upon request. Disposal of the collected materials must be in accordance with applicable DNR rules and regulations.
