Washington Revised Code Title 70A. Environmental Health and Safety § 70A.20.050. Civil penalties

(1) Any person who violates any rule adopted by the department under this chapter shall be subject to a civil penalty not to exceed one hundred dollars imposed by local government pursuant to this section.  An action under this section shall not preclude enforcement of any provisions of the local government noise ordinance.

Penalties shall become due and payable thirty days from the date of receipt of a notice of penalty unless within such time said notice is appealed in accordance with the administrative procedures of the local government, or if it has no such administrative appeal, to the pollution control hearings board pursuant to the provisions of chapter 43.21B RCW and procedural rules adopted thereunder.  In cases in which appeals are timely filed, penalties sustained by the local administrative agency or the pollution control hearings board shall become due and payable on the issuance of said agency or board's final order in the appeal.

(2) Whenever penalties incurred pursuant to this section have become due and payable but remain unpaid, the attorney for the local government may bring an action in the superior court of the county in which the violation occurred for recovery of penalties incurred. In all such actions the procedures and rules of evidence shall be the same as in any other civil action.
