(A) Any gasoline, benzene, naphtha, solvent, fuel oil or any liquid, solid or gas that would cause or tend to cause flammable or explosive conditions to result in the wastewater system.

(B) Any wastes containing toxic or poisonous solids, liquids or gases in such quantities that, alone or in combination with other wastes, may create a health hazard for humans, animals or the local environment, interfere detrimentally with wastewater treatment processes, causes a public nuisance, or cause any hazardous condition to occur in the POTW.

(C) Any waste having a pH lower than 6.0 or higher than 10.5 standard units or having any corrosive or detrimental characteristic that may cause injury to wastewater treatment or maintenance personnel or may cause damage to the POTW.

(D) Any solids or viscous substances of such size or in such quantity that they may cause obstruction to flow in the sewer or be detrimental to the POTW. These objectionable substances include, but are not limited to, asphalt, dead animals, offal, ashes, sand, stone dust, FOG (fats, oil and grease), mud, straw, industrial process shavings, metal, glass, rags, feathers, tar, wood, whole blood, paunch manure, bones, hair and fleshings, entrails, paper dishes, paper cups, milk containers, or other similar paper products, either whole or ground.

(E) Any rainwater, stormwater, groundwater, street drainage, subsurface drainage, roof drainage, yard drainage, water from yard fountains, ponds or lawn sprays or any other uncontaminated water, except as permitted under Section 14.08.010.

(F) Having a temperature higher than one hundred fifty (150) degrees Fahrenheit (sixty-five (65) degrees Celsius) or any wastewater having a temperature which will inhibit biological activity in the POTW resulting in interference. In no circumstances shall wastewater have a temperature at the introduction of the wastewater treatment plant greater than one hundred four (104) degrees Fahrenheit (forty (40) degrees Celsius).

(G) Containing more than one hundred (100) mg/l of oil or grease.

(H) Any strongly odorous waste tending to create odors.

(I) Any waste that if otherwise disposed of would be hazardous waste under 40 CFR Part 261.

(J) Any substance promoting or causing the promotion of toxic gases.

(K) Any wastes requiring an excessive quantity of chlorine or other chemical compound used for disinfection purposes.

(L) Any excessive amounts of deionized water, steam condensate, distilled water or single pass cooling water.

(M) Any radioactive waste of such half-life or concentrations as may exceed limits established by the Director in compliance with applicable state or federal regulations.

(N) Any waste producing excessive discoloration of wastewater or treatment plant effluent.

(O) Any pollutants, including oxygen demanding pollutants, released in a discharge at a flow rate and/or pollutant concentration which will cause interference with the POTW.

(P) The discharge of toxic or nontoxic materials including, but not limited to, all heavy metals, cyanide, phenols, chlorinated hydrocarbons, and other organic compounds shall be limited to that concentration which complies with all state and federal discharge limitations, and which does not interfere with the operation of the wastewater treatment facility, nor cause pass through, or which might otherwise cause the wastewater treatment facility to violate its NPDES permit.

(Q) Any waste prohibited by current federal or state regulations or City industrial wastewater discharge permits.

(R) Any waste discharged by a categorical industry that is greater in concentration than limitations specified by the National Categorical Standard that applies to that industry.

(S) Any pollutant which creates a fire or explosion hazard, including, but not limited to, wastestreams with a closed cup flashpoint of less than one hundred forty (140) degrees Fahrenheit (sixty (60) degrees Centigrade).

(T) Any pollutants that result in toxic gases, vapors and fumes in a quantity that may cause acute worker health and safety problems.

(U) Any petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that cause pass through, interference or inhibition at wastewater treatment facility.

(V) Trucked or hauled pollutants, except at discharge points designated by the Director. (Ord. 22-42 § 45, 2022; Ord. 09-29 § 4, 2009; Ord. 01-101 § 1, 2001; Ord. 92-22 § 2, 1992; Ord. 84-105 § 1, 1984.)
