It shall be unlawful for any person to discharge or cause to be discharged any wastewater into any storm drain or watercourse within the city, except for those persons with approved permits for such discharges.
(Ordinance 450-12, sec. 3(A), adopted 1/19/12)
No person shall discharge or cause to be discharged any stormwater, groundwater, roof runoff, subsurface drainage or drainage from downspouts, yard drains, yard fountains and ponds, or lawn sprays into any sanitary sewer. Water from swimming pools, unpolluted industrial water, or cooling water from various equipment shall not be discharged into sanitary sewers if an alternate acceptable means of disposal is available. If an alternate acceptable means of disposal is not available, such water may be discharged into the sanitary sewer provided the water meets the discharge prohibitions and limitations of this article.
(Ordinance 450-12, sec. 3(B), adopted 1/19/12)
It shall be unlawful for any person to deposit or discharge into the sanitary sewer any wastewater or solid, including trucked or hauled wastes, unless such deposit or discharge, at a designated discharge point, has been approved by the authority.
(Ordinance 450-12, sec. 3(C), adopted 1/19/12)
No person shall contribute or cause to be discharged directly or indirectly, into any public sanitary sewer, any of the following described substances, materials, water or waste:
(1) 
Any liquid or vapor having a temperature higher than one hundred fifty (150) degrees Fahrenheit (65 degrees centigrade).
(2) 
Any water or waste which contains wax, grease, oil, plastic or other substance that will solidify or become discernibly viscous at temperatures between thirty-two (32) degrees to one hundred fifty (150) degrees Fahrenheit, thereby contributing to clogging, plugging or otherwise restricting the flow of wastewater through the collection system.
(3) 
Pollutants which create a fire or explosion hazard in the sewer system or POTW, including but not limited to waste streams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees centigrade using the test methods specified in 40 CFR part 261.21. This includes flammable or explosive liquids, solids or gases such as gasoline, kerosene, benzene, naphtha, etc., which by reason of their chemical properties or quantity may be sufficient, either alone or by interaction, to cause fire or explosion.
(4) 
Solid or viscous substances in quantities capable of causing obstruction in the flow in sewers or other interference with proper operation of the POTW, such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, whole blood, paunch manure, hair and fleshings, entrails, lime slurry, lime residues, slops, chemical residues, paint residues, or bulk solids.
(5) 
Any garbage that has not been properly comminuted or shredded to such a degree that all particles will be carried freely under the flow conditions normally prevailing in public sewers, with no particle greater than one-half (1/2) inch in any dimension.
(6) 
Any noxious or malodorous substances which can form a gas which, either singly or by interaction with other wastes, is capable of causing objectionable odors or hazards to life or forms solids in concentrations exceeding limits established in this article, or creates any other condition deleterious to structures or treatment processes, or requires unusual provisions, attention or expense to handle such material.
(7) 
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 which may prevent entry into the sewers for their maintenance and repair.
(8) 
Any substance which may cause the POTW’s effluent or treatment residues, sludges, or scums to be unsuitable for reclamation and reuse or to interfere with the reclamation process as determined pursuant to criteria in this article. In no case shall a substance discharged to the POTW cause the POTW to be in 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 Resource Conservation and Recovery Act, the Clean Air Act, the Toxic Substances Control Act or state standards applicable to the sludge management method being used.
(9) 
Any substance which will cause the POTW to violate its TPDES or other disposal system permits, or the receiving stream water quality standards.
(10) 
Any substance with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions.
(11) 
Any slugload. Also, oxygen-demanding pollutants (BOD, etc.) released in a discharge at a flow rate and/or pollutant concentration which, either singly or by interaction with other pollutants, will cause interference with the POTW.
(12) 
Any wastewater which causes a hazard to human life or creates a public nuisance.
(13) 
Any dump or slugload of waste containing concentrated organic solvents or mixtures of solvents which are defined as hazardous by the Federal Resource Conservation and Recovery Act.
(14) 
Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause obstruction of flow in the sewer line, or interference or pass-through.
(15) 
Deny or condition new or increased contributions of pollutants, or changes in the nature of pollutants, to the POTW by industrial users where such contributions do not meet applicable pretreatment standards and requirements or where such contributions would cause the POTW to violate its TPDES permit.
(16) 
Hydrogen sulfide, sulfur dioxide or nitrous oxide in excess of 10 parts per million.
(17) 
Radioactive wastes or isotopes with a half-life or concentration exceeding limits established by the authority in compliance with applicable state or federal regulations.
(18) 
Toxic pollutants in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, or pass through the treatment plant and impair aquatic life in receiving water, as expressed by the results of acute or chronic toxicity tests of the POTW effluent.
(19) 
A temperature which inhibits or interferes with biological activity in the POTW treatment plant. In no case shall wastewater be introduced which would have a temperature exceeding 40°C (104°F) upon entering the POTW treatment plant.
(20) 
Pollutants in excess of the limitations established in an applicable categorical pretreatment standard set forth in title 40 of the Code of Federal Regulations.
(21) 
Wastewaters which emanate vapors causing the atmosphere in the sewer system to exceed 20% of the lower explosive limit in the immediate area of the discharge.
(22) 
BTEX concentration greater than 1.0 mg/l.
(23) 
Oil and grease.
(A) 
Petroleum oil, nonbiodegradable cutting oil, or non-polar products of mineral oil origin in concentrations greater than 200 mg/l.
(B) 
Visible free floatable polar oils, fats, or grease or a concentration greater than 250 mg/l in wastewater discharged from industrial or commercial facilities into the POTW.
(C) 
In no case shall discharges in amounts that cause interference or operational problems with the POTW be allowed.
(Ordinance 450-12, sec. 3(D), adopted 1/19/12)
No person shall contribute or cause to be discharged, directly or indirectly, into any sanitary sewer any wastewaters containing or having:
(1) 
Acids or alkalis capable of causing damage to sewage disposal structures or personnel or having a pH value lower than 5.0 or higher than 12.0.
(2) 
Metals in the form of compounds or elements with total concentrations exceeding the following:

(4) 
The director may develop best management practices (BMPs), by ordinance or in individual wastewater discharge permits, to help implement local limits and other pretreatment standards and the requirements of this article.
(5) 
A person commits an offense if with criminal negligence the person processes or stores pollutants, substances, or wastewater prohibited by this article in such a manner that they could be discharged to the POTW.
