A. General. Users shall provide all known, available, and reasonable methods of prevention, control, and treatment (AKART) as required to comply with this chapter, and shall achieve compliance with all applicable pretreatment standards and requirements set out in this chapter within the time limitations specified by the EPA, the state, or the director, whichever is more stringent.

Any facilities required to pretreat wastewater to a level acceptable to the city shall be provided, operated, and maintained at the user’s expense.

In addition, the director may establish best management practices (BMPs) for particular groups of users. These BMPs may include, but are not limited to, types or methods of pretreatment technology to be used, methods of source control, minimum maintenance requirements, spill prevention practices, or other requirements as deemed necessary.

B. If a failure to maintain any GRS results in partial or complete blockage of the building sewer, private sewer system discharging to the city sewer system, or other parts of the city sewer system, or adversely affects the treatment or transmission capabilities of the POTW, or requires excessive maintenance by the city, or poses a possible health hazard, the discharger responsible for the facilities shall be subject to the remedies herein, including cost recovery, enforcement and penalties. (Ord. 3071-08 § 2.7, 2008.)
