[R.O. 2009 §13.16.170]
A. 
Any pollutant introduced to a publicly owned treatment works facility by a non-domestic source, which would create an atmosphere causing the POTW to violate its NPDES permit, or not meet applicable pretreatment standards, shall not pass through the POTW or interfere with the operation or performance of the works. The following materials, substances and wastes shall not be discharged into the City sewers:
1. 
Any water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of one hundred (100) ppm or containing substances which may solidify or become viscous at temperatures between thirty-two degrees Fahrenheit (32°F) and one hundred fifty degrees Fahrenheit (150°F).
2. 
Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths (¾) horsepower or greater shall be the subject to the review and approval of the Director of Utilities.
3. 
Any pollutants which create a fire or explosion hazard in the POTW including, but not limited to, waste streams with a closed cup flashpoint of less than one hundred forty degrees Fahrenheit (140°F) or sixty degrees Celsius (60°C) using the test methods specified in 40 CFR 261.21. Any gasoline, benzene, naphtha, diesel fuel, fuel oil or other flammable or explosive liquid, solid or gas which creates an atmosphere within the wastewater system that exceeds the following limits: At no time shall two (2) successive readings on an explosion hazard meter, at the point of discharge into the system (or at any point in the system) be more than five percent (5%) nor any single reading over ten percent (10%) of the lower explosive limit (LEL) of the meter.
4. 
Any waters or wastes containing strong acid, iron pickling wastes or concentrated plating solutions whether neutralized or not.
5. 
Petroleum oil, non-biodegradable cutting oil or products of mineral oil origin in amounts that will cause interference or pass through. Any solid or viscous material in quantities capable of causing obstruction to the flow in sewers or interference with the proper operation of any portion of the wastewater system such as, but not limited to, the following substances: ashes, wax, paraffin, cinders, sand, bones, mud, straw, shavings, scrap metal, glass, rags, lint, feathers, tar, plastics, wood, sawdust, paunch manure, hair and flesh, entrails, whole blood, lime slurry, lime residues, acid residues, acetylene generation sludge, grinding compounds, chemical or paint residues, bulk solids, shredded paper, cardboard or similar wastes.
6. 
Any whey.
7. 
Pollutants which result in the presence of toxic gases, vapors or fumes within the POTW in a quantity that may cause acute worker health and safety problems. Any noxious or malodorous gas or other substance, such as detergent foam, which either singly or by interaction with other wastes is capable of creating a public-nuisance or hazard to life or of preventing safe entry into sewers for purposes of inspection, maintenance or repair.
8. 
Any concentrated dye wastes or other wastes which are either highly colored or could become highly colored by reacting with other wastes.
9. 
Any material or substance not specifically mentioned in this Section which, in itself or by interaction with other wastes, becomes corrosive, toxic or noxious, irritating to humans and animals or adversely affects any treatment process, sewage works or the receiving watercourse.
[R.O. 2009 §13.16.180]
A. 
No person shall discharge or cause to be discharged into any City sewer any of the following substances in excess of stated quantities or concentrations without first having obtained prior approval from the Director of Utilities:
1. 
Any liquid or vapor having a temperature in excess of one hundred fifty degrees Fahrenheit (150°F) upon entry into the sewerage system or in excess of one hundred four degrees Fahrenheit (104°F) upon entering the wastewater treatment plant.
2. 
Wastes having a pH less than six (6.0) or greater than nine and one-half (9.5) or otherwise having chemical properties which are hazardous or capable of causing damage to the sewage works or personnel.
3. 
Any waters of wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other waste, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the sewage treatment plant. The industries for which the Environmental Protection Agency has published regulations establishing categorical pretreatment standards shall be subject to those standards, unless more stringent local limits exist whereby the industry shall be subject to the stricter of the two (2) standards. Industries or pollutants for which there are no existing categorical standards shall be subject to the following local limits:
24-Hour Maximum

Note: Concentrations listed above are total substance dissolved plus suspended.
4. 
Any radioactive wastes or isotopes of such half-life or concentration which may exceed limits established by the Director of Utilities or latest State and Federal regulations.
5. 
Any wastes which are of unusual volume, concentration of solids or composition, as for example in total suspended solids of inert nature (such as Fuller's earth) and/or in total dissolved solids (such as sodium chloride, calcium chloride or sodium sulfate) or which have a BOD which exceeds the standards of normal sewage (as defined in Article I).
B. 
Limits established in this Section may be modified and the volume and concentration of contributions from users may be subject to more stringent requirements by the Director so that the aggregate contributions within the City's treatment plant do not cause treatment difficulties or produce a wastewater of treatment facility effluent, air emission or sludge discharge in violation of the limits and requirements of applicable Federal and State regulations, NPDES permits or applicable pretreatment standards.
C. 
In any instance in which Federal and/or State requirements or limitations are more stringent than the limitations set forth in this Article, said requirements and limitations on discharges shall be met by all users subject to such requirements or limitations.
[R.O. 2009 §13.16.190]
A. 
If any wastewater containing any of the substances or possessing any of the characteristics enumerated in Article IV of this Chapter or which, in the judgment of the Director, may interfere with the wastewater system or have a harmful effect on receiving waters or would cause the POTW to violate its NPDES permit, does not meet applicable pretreatment standards and is discharged or is proposed to be discharged into the wastewater system, the Director may:
1. 
Refuse to allow discharge of the waste into the City's wastewater system;
2. 
Require pretreatment to a condition acceptable for discharge into the wastewater system;
3. 
Require control over the quantities and rates of discharge;
4. 
Require payment to cover added cost of handling and treating the wastes not covered by existing taxes or sewer charges;
5. 
Require the development of compliance schedules for meeting any applicable pretreatment standards;
6. 
Require the submission of report necessary to assure compliance with any applicable pretreatment standards; (See Article VI, Section 715.330.)
7. 
Carry out all inspections, surveillance and monitoring necessary to determine compliance with any applicable pretreatment standards;
8. 
Obtain remedies for non-compliance by any user. Such remedies may include injunctive relief, the civil penalties specified in Article VII of this Chapter or appropriate criminal penalties; and/or
9. 
Terminate service.
B. 
When considering the above alternatives, the Director shall ensure that the City is in compliance with all Federal and State requirements or limitations. The Director shall also take into consideration the cost-effectiveness, economic impact of each alternative on the user and the City and any other factors relevant to the situation. If the Director permits the pretreatment or equalization of waste flows, the design and installation of the facilities and equipment shall be subject to review and approval by the Director. The Director shall either approve or reject the pretreatment design within ninety (90) days after its submittal.
[R.O. 2009 §13.16.200]
No user shall increase the use of potable or process water in any way for the purpose of diluting a discharge as partial or complete substitute for pretreatment required to comply with the provisions of this Article.
[R.O. 2009 §13.16.210]
Each user shall provide safeguards against the accidental discharge into the wastewater system of prohibited or restricted substances. Facilities to prevent accidental discharge to the wastewater system of prohibited or restricted substances shall be provided and maintained at the user's expense. In the case of any accidental spill, it shall be the responsibility of the user to report all such accidents to the Director in accordance with the requirements set forth in Article VI, Section 715.290 of this Chapter. Expenses incurred by the City during the abatement of spill events may be charged to the responsible person.
[R.O. 2009 §13.16.220]
At the discretion of the Director, the POTW may accept the discharge at the treatment works from private domestic waste haulers. This discharge point shall be the manhole at the headworks of the plant just ahead of the comminutor at the City's wastewater treatment facility on South Ingram Road, Sikeston, Missouri. The hauler shall, annually, register all vehicles with the Director and with each load the hauler shall sign a form indicating the name(s) and address(es) of points of origin of the waste. The POTW operator shall retain a sample of each load for testing at the discretion of the Director. All private waste haulers shall pay a minimum fee of five dollars ($5.00) per load.
