§ 13.20.211. Specific discharge prohibitions.

No person shall contribute or cause to be contributed into the POTW the following pollutants, substances or wastewater:

A.

Any liquids, solids, or gases which by reason of their nature or quantity are, or may be, sufficient, either alone or by interaction with other substances, to cause fire, explosion, or in any other way be injurious to the POTW or to operation of the POTW including, but not limited to, wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Centigrade;

B.

Any solids or viscous substance of such size or character, or in such quantity that they may cause obstruction to flow in the collection system or be detrimental to proper wastewater treatment plant operations;

C.

Any wastewater having a pH less than 5.0 or greater than 11.5, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment, and/or personnel of the POTW;

D.

Any wastewater containing hazardous substances or toxic pollutants, in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any wastewater treatment process including sludge disposal, constitute a hazard to human or animals, or create a hazardous effect or acute or chronic toxicity in the receiving waters of the POTW;

E.

Any noxious or malodorous liquids, gases, or solids which either singly or by interaction with other wastes are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for maintenance and repair;

F.

Any substance which may cause the POTW's effluent, or any other product of the POTW such as residues, sludges, or scums, to be unsuitable for reclamation and reuse. In no case shall a substance discharged to the POTW cause the POTW to violate applicable sludge use or disposal 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, Clean Air Act, Toxic Substances Control Act, Resource Conservation and Recovery Act, Marine Protection, Research and Sanctuaries Act, or state regulations;

G.

Any wastewater which imparts color which cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions;

H.

Any wastewater having a temperature greater than 60 degrees Centigrade (140 degrees Fahrenheit), or which will inhibit biological activity in the POTW treatment plant resulting in interference, but in no case wastewater which causes the temperature at the introduction into the POTW treatment plant to exceed 40 degrees Centigrade (104 degrees Fahrenheit);

I.

Any pollutants, including oxygen demanding pollutants (BOD, etc.), released at a flow rate and/or pollutant concentration which will cause interference, pass through, or otherwise cause violation of the NPDES permit or receiving water quality standards;

J.

Any wastewater containing any radioactive wastes or isotopes except in compliance with applicable state or federal regulations;

K.

Any discharge which may, alone or in combination with other waste substances, result in the presence of toxic or poisonous solids, liquids, gases, vapors, or fumes in the POTW in such quantities that would create a hazard, public nuisance, or acute worker health and safety problems;

L.

Any stormwater, groundwater, well water, street drainage, sub-surface drainage, roof drainage, yard drainage, water from yard fountains, ponds, lawn sprinklers, or any type of surface water or unpolluted water. The Director may approve, on a temporary basis, the discharge of such waters to the POTW when no reasonable alternative method of disposal is available, subject to the payment of all applicable user charges and fees by the discharger. Water from swimming pools, wading pools, and therapy pools may be discharged to the sewerage system between 8:00 p.m. and 6:00 a.m., unless specifically prohibited by the Director;

M.

Any wastewater, sludge or septic waste removed from a cesspool, septic tank, chemical toilet or similar waste holding device, except such wastes which are discharged to the POTW in accordance with a wastewater discharge permit issued by the City. No wastehauler discharging septic waste to the POTW shall discharge constituents in excess of the limits for wastehaulers set forth by resolution of the City and amended from time to time;

N.

Any trucked or hauled pollutants or wastewater, except at such place and in such manner as authorized by a wastewater discharge permit issued by the City;

O.

Any pesticides or fertilizers in amounts which may cause interference or pass through;

P.

Any non-biodegradable cutting oil, petroleum oil, refined petroleum products, or products of mineral oil origin in amounts which could cause interference or pass through;

Q.

Any substances containing polychlorinated biphenyls (PCBs). PCBs include, but are not limited to, the following: Aroclors 1016, 1221, 1228, 1232, 1242, 1248, 1254, 1260 and 1262;

R.

Any excessive quantities of dispersed biodegradable oils or fats such as lard, tallow, or vegetable oil or any other substances that may precipitate, solidify, or become viscous at temperatures between 140 degrees Fahrenheit;

S.

Any pretreatment wastes. All pretreatment wastes shall be disposed of in accordance with all applicable federal, state, county, and other local laws and regulations.
