8.

Any excessive concentrations of nonbiodegradable oil, petroleum oil or refined petroleum products;

9.

Any dispersed biodegradable oils and fats, such as lard, tallow or vegetable oil in excessive concentrations that would tend to cause adverse effects on the sewerage system;

Any substance promoting or causing the promotion of toxic gases;

17.

Any waste having a temperature of one hundred twenty degrees Fahrenheit or higher;

18.

Any wastes requiring an excessive quantity of chlorine or other chemical compound used for disinfection purposes;

Any waste containing substances that may precipitate, solidify or become viscous at temperatures between fifty degrees Fahrenheit and one hundred degrees Fahrenheit;

22.

Any waste producing excessive discoloration of wastewater or treatment plant effluent;

23.

Any garbage or waste that is not ground sufficiently to pass through a three-eighth-inch screen;

24.

Any wastes containing excessive quantities of iron, boron, chromium, phenols, plastic resins, copper, nickel, zinc, lead, mercury, cadmium, selenium, arsenic or any other objectionable materials toxic to humans, animals, the local environment or to biological or other wastewater treatment processes;

25.

Any blow down or bleed water from cooling towers or other evaporative coolers exceeding one-third of the makeup water;

26.

Any single pass cooling water;

27.

Any excessive quantities of radioactive material wastes;

28.

Recognizable portions of the human anatomy;

29.

The contents of any swimming or decorative pool, pond, storage tank, or any other container in excess of two hundred fifty gallons, whether containing contaminated or uncontaminated water, except upon issuance of a temporary permit as described in Section 14.08.515, hereinbelow.

No person shall discharge or cause to be discharged to the city's sewerage system, or to any sewer which directly or indirectly connects to the city's sewerage system, any wastes which, in the opinion of the director, may have an adverse or harmful effect on sewers, maintenance personnel, wastewater treatment plant personnel or equipment, treatment plant effluent quality, public or private property, or may otherwise endanger the public, the local environment or create a public nuisance. The director, in determining the acceptability of specific wastes, shall consider the nature of the waste and the adequacy and nature of the collection, treatment and disposal system available to accept the waste.
