Except as hereinafter provided, no person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewer:

Any liquid or vapor having a temperature higher than one hundred fifty degrees Fahrenheit (150° F.) or such quantities causing the temperature in the sewer to exceed one hundred four degrees Fahrenheit (104° F.).

Any water or waste which may contain more than one hundred (100) parts per million, by weight, of fat, oil or grease.

Any gasoline, benzine, naphtha, fuel oil or other flammable or explosive liquid, solid or gas or waste streams with a closed cup flash point of less than one hundred forty degrees Fahrenheit (140° F.) or sixty degrees Centigrade (60° C.) using the test methods in 40 CFR 261.21.

Any garbage that has not been properly shredded.

Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, paunch manure or any other solid or viscous substance capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewerage works.

Any waters or wastes having a pH lower than five and five-tenths (5.5) or higher than nine (9.0), or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works.

Any material or substance not specifically mentioned in this Section which is in itself self-corrosive, irritating to human beings and animals, toxic or noxious, or which by interaction with other wastes is capable of producing undesirable effects, including deleterious action on the sewage works, adversely affect any treatment process, constitute a hazard to humans or animals, or have an adverse effect upon the receiving stream.

Any waters or wastes containing suspended solids in excess of three hundred fifty (350) parts per million or of such character and quantity that unusual attention or expense is required to handle such materials in the sewage works.

Toxic or poisonous solids, liquids, or gases, such as heavy metals, cyanides, pesticides, non-biodegradable synthetic organics, or other materials which in sufficient quantity, either singly or by interaction with other wastes, might injure or interfere with wastewater treatment processes, create a hazardous sludge, constitute a hazard to humans or animals utilizing receiving waters downstream from the treatment plant or create a public nuisance therein.

10.

Any unpolluted waters, such as storm water, groundwater, roof runoff, subsurface drainage, swimming pool drainage, surface drainage, artesian well water, condensate, deionized water, or discharge from interior or exterior foundation drains, unless authorized in a manner deemed appropriate by the Public Works Director or assigned designee.

11.

Any wastewater which would cause the treatment works to violate its NPDES permit, State hazardous waste regulations, the receiving water's quality standards, or any other requirement of other agencies having jurisdiction over the sewer collection and treatment system.

12.

Any substance which causes the wastewater treatment system's waste activated sludge to violate the 40 CFR Part 503 sludge regulations applicable to the required sludge management methods being used.

13.

Any wastewater containing any radioactive waste or isotopes, except as authorized in a manner deemed appropriate by the Superintendent in compliance with applicable State or Federal regulations.

14.

Any wastewater containing chemicals or pharmaceuticals.

15.

Any concentrated plating wastes or metallic pickling wastes whether neutralized or not.

16.

Any pollutants which result in the presence of toxic gases, vapors, or fumes within the sewage collection system in a quantity that may produce a safety hazard.

17.

Any trucked or hauled pollutants, except at discharge points designated by the Superintendent.

18.

Any wastes containing phenolic compounds over ten (10) parts per million expressed as phenol.

19.

Any wastes containing cyanides or compounds capable of liberating hydrocyanic gas over two (2) parts per million as expressed as hydrogen cyanide.

20.

Any wastes containing sulfides over ten (10) parts per million expressed as hydrogen sulfide.

21.

Chlorinated solvents.

22.

Wastewater which imparts color which cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently impart color to the treatment plant's effluent, thereby violating the City's NPDES permit.

23.

Sludges, screenings, or other residues from the pretreatment of industrial wastes.

24.

Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a discharge at a flow rate and/or pollutant concentration which will cause interference with the waste water treatment plant.

25.

Detergents, surface-active agents, or other substances which may cause excessive foaming at the waste water treatment plant.
