§ 26.50.050. Prohibited acts.

A.

It shall be unlawful for any user to:

1.

Introduce or cause to be introduced into the municipal sewerage system any pollutant or wastewater which causes pass through or interference. This general prohibition and the specific prohibitions below apply to all users whether or not they are subject to categorical pretreatment standards or any other national, state, or local pretreatment standards or requirements.

2.

Discharge or cause to be discharged any of the following described pollutants, substances, or wastewater into the municipal sewerage system:

a.

Any stormwater, surface water, surface runoff, groundwater, roof runoff, subsurface drainage, cooling water or other unpolluted water.

b.

Any water or wastewater which contains petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through or which in the opinion of the utility are in amounts greater than that which would be normally construed as incidental in normal discharges.

c.

Any solid or viscous substance, or liquid that can become viscous when cooled, in amounts capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewerage system such as, but not limited to, fat, grease, uncomminuted garbage, animal guts or tissues, hair, hide, fleshings or entrails.

d.

Any wastewater which creates a fire or explosive hazard, including, but not limited to, wastewaters with a closed-cup flashpoint of less than 140°F (60°C) using the test methods specified in 40 CFR 261.21. At no time shall two (2) successive readings on an explosion meter, at the point of discharge into the system (or at any point in the system), be more than five (5) per cent nor any single reading over ten (10) per cent of the lower explosive limit (LEL) of the meter.

e.

Any wastewater having a pH lower than 5.0 or higher than 12.5 at any time, or having any corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewerage works.

f.

Any wastewater which results in the presence of toxic gases, vapors, or fumes in a quantity that, in the opinion of the utility, may cause worker health and safety problems.

g.

Any wastewater containing radioactive substances except in compliance with applicable state or federal regulations.

h.

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 health, or that are sufficient to prevent entry into the municipal sewerage system for its maintenance and repair.

i.

Any substance that will cause the utility to violate its NPDES permit.

j.

Any substance that may cause the municipal sewerage system's treatment residues, sludges, incinerator ash or scums to be unsuitable for reclamation and reuse or to interfere with the reclamation process.

k.

Any wastewater that causes the temperature at the treatment works influent to exceed 40 degrees Celsius (104 degrees Fahrenheit).

l.

Any pollutants, including oxygen demanding pollutants, released at a flow rate or concentration that, either singly or by interaction with other pollutants, will interfere with operation of the municipal sewerage system.

m.

Any wastewater containing medical wastes from industrial users including but not limited to hospitals, clinics, offices of medical doctors, convalescent homes, medical laboratories or other medical facilities.

3.

Prohibited connection of sanitary sewer with storm sewer system. Interconnect or cause to be interconnected directly or indirectly any part of a sanitary sewer system with any part of a storm sewer system.

4.

Prohibited discharge at unapproved location. Discharge or cause to be discharged into a sanitary sewer any waters or wastes whatsoever other than through an approved, permanent sewer extension, or at a sewage dump station or other location that has been specifically so designated by the utility.

B.

Vandalism. No person or entity shall willfully or negligently break, damage, destroy, uncover, deface, tamper with, or prevent access to any structure, appurtenance or equipment, or other part of the municipal sewerage system.

C.

Any person or entity found in violation of this section shall be subject to the sanctions set out in this chapter.
