Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas;
2. 
Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, 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, including, but not limited to, cyanides in excess of two milligrams per liter as cyanide ion in the wastes, as discharged to the public sewer;
3. 
Any waters or wastes having a pH lower than 5.5 or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works;
4. 
Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewer works such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.
D. 
No person shall discharge or cause to be discharged the following described substances, materials, waters or wastes, if it appears likely, in the opinion of the director, that such wastes can harm either the sewers, sewage treatment process or equipment, have an adverse effect on the natural outlet, or can otherwise endanger life, limb, public property, or constitute a nuisance. In forming his opinion as to the acceptability of these wastes, the director will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant, and other pertinent factors. The substances prohibited are:
1. 
Any liquid or vapor having a temperature higher than 150 degrees Fahrenheit;
2. 
Any water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of one hundred milligrams per liter, or containing substances which may solidify or become viscous at temperatures between 32 and 150 degrees Fahrenheit;
3. 
Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths horsepower or greater shall be subject to the review and approval of the director;
4. 
Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions, whether neutralized or not;
5. 
Any waters or wastes containing iron, chromium, copper, zinc and similar objectionable or toxic substances, or wastes exerting an excessive chlorine requirement, to such degree that any such material received in the composite sewage at the sewage treatment plant exceeds the limits established by the director for such materials;
6. 
Any waters or wastes containing phenols or other waste or odor-producing substances, in such concentrations exceeding limits which may be established by the director as necessary, after treatment of the composite sewage, to meet the requirements of the state, federal or other public agencies of jurisdiction for such discharge to the receiving waters;
7. 
Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the director in compliance with applicable state or federal regulations;
8. 
Any waters or wastes having a pH in excess of 9.5;
9. 
Materials which exert or cause:
a. 
Unusual concentrations of inert suspended solids (such as, but not limited to, fuller's earth, lime slurries and lime residues) or of dissolved solids (such as, but not limited to, sodium chloride and sodium sulfate),
b. 
Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions),
c. 
Unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works,
d. 
Unusual volume of flow or concentration of wastes constituting slugs as defined herein;
10. 
Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
E. 
If the waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in subsection D of this section, and which, in the judgment of the director, may have a deleterious effect upon the sewage works, processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the director may:
1. 
Reject the wastes;
2. 
Require pretreatment to an acceptable condition for discharge to the public sewers;
3. 
Require control over the quantities and rates of discharge; and/or
4. 
Require payment to cover the added cost of handling and treating the wastes not covered by sewer charges under the provisions of subsection J of this section. If the director permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the director, and subject to the requirements of all applicable codes, ordinances and laws.
F. 
Grease, oil and grit interceptors shall be provided when, in the opinion of the director, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, grit or other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the director and shall be located as to be readily and easily accessible for cleaning and inspection.
G. 
Where preliminary treatment or rate-of-flow controller facilities are provided for any waters or wastes, they shall be maintained continuously, in satisfactory and effective operation, by the owner, at his expense.
H. 
When required by the director, the owner of any property service by a building sewer carrying industrial wastes shall install a suitable control manhole, together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of wastes. Such manhole, when required, shall be accessibly and safely located and shall be constructed in accordance with plans approved by the director. The manhole shall be installed by the owner, at his expense, and shall be maintained by him so as to be safe and accessible at all times.
I. 
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this chapter, shall be determined in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater, published by the American Public Health Association, and shall be determined at the control manhole provided or upon suitable samples taken at said control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out in the customarily accepted methods to reflect the effect of constituents upon the sewer works and to determine the existence of hazards of life, limb and property.
J. 
Nothing in this chapter shall be construed as preventing any special agreement or arrangement between the city and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the city council for treatment, subject to payment therefor by the industrial concern.
