The council may take any of the following regulatory actions to enforce this chapter to meet the provisions of RCW 80.50.040 or 70.94.422.

(1) Enforcement actions—Notice of violation. At least thirty days prior to the commencement of any formal enforcement action under RCW 70.94.430 and 70.94.431 (1) through (7), the council shall cause written notice to be served upon the alleged violator or violators. The notice shall specify the provision of this chapter or rule or regulation alleged to be violated and the facts alleged to constitute a violation thereof, and may include an order that necessary corrective action be taken within a reasonable time. In lieu of an order, the council may require that the alleged violator or violators appear before it for the purpose of providing information to the council pertaining to the violation or the charges complained of. Every notice of violation shall offer the alleged violator an opportunity to meet with the council prior to the commencement of enforcement action.

(2) Civil penalty.

(a) All penalties assessed as the result of air emission violations shall be consistent with RCW 70.94.332, 70.94.430, 70.94.431 (1) through (7), and 70.94.435. Any person who violates any of the provisions of chapter 70.94 RCW may incur a civil penalty in an amount as set forth in RCW 70.94.431. Each such violation shall be separate and distinct and, for a continuing violation, each day's continuance shall be a separate and distinct violation.

Any person who fails to take action as specified by an order issued pursuant to this chapter shall be liable for a civil penalty as set forth by RCW 70.94.431 for each day of continued noncompliance.

(b) Penalties incurred but not paid shall accrue interest, beginning on the ninety-first day following the date that the penalty becomes due and payable, at the highest rate allowed by RCW 19.52.020 on the date that the penalty becomes due and payable. If violations or penalties are appealed, interest shall not begin to accrue until the thirty-first day following final resolution of the appeal.

The maximum penalty amount established in RCW 70.94.431 may be increased annually to account for inflation as determined by the state office of economic and revenue forecast council.

(c) Each act of commission or omission which procures, aids, or abets in the violation shall be considered a violation under the provisions of this section and subject to the same penalty. The penalties provided in this section shall be imposed pursuant to RCW 70.94.422.

(d) All penalties recovered under this section by the council shall be paid into the state treasury and credited to the air pollution control account established in RCW 70.94.015.

(e) In addition to other penalties provided by this chapter, persons knowingly under-reporting emission or other information used to set fees, or persons required to pay emission or permit fees who are more than ninety days late with such payments may be subject to a penalty equal to three times the amount of the original fee owed.

(3) Assurance of discontinuance. The chair, or his/her authorized representative, may accept an assurance of discontinuance of any act or practice deemed in violation of this chapter. Any such assurance shall specify a time limit during which discontinuance is to be accomplished. Failure to perform the terms of any such assurance shall constitute prima facie proof of a violation of this chapter which make the alleged act or practice unlawful for the purpose of securing an injunction or other relief from the superior court.

(4) Restraining orders, injunctions. Whenever any person has engaged in, or is about to engage in, any acts or practices which constitute or will constitute a violation of any provision of this chapter, the council, after notice to such person and an opportunity to comply, may petition the superior court of the county wherein the violation is alleged to be occurring or to have occurred for a restraining order or a temporary or permanent injunction or another appropriate order.

(5) Emergency episodes. The council may issue such orders as authorized by chapter 80.50 RCW, whenever an air pollution episode forecast is declared.

(6) Compliance orders. The council may issue a compliance order in conjunction with a notice of violation. The order shall require the recipient of the notice of violation either to take necessary corrective action or to submit a plan for corrective action and a date when such action will be initiated.
