(1) The penalty must be paid to the director within 30 days after an order assessing a civil penalty becomes final by operation of law or on an appeal.

(3) If the licensed contractor or certificate of competency holder fails to pay the full penalty or comply with the payment plan as provided by subsection (2) of this section:

(a) The license or certificate of competency will be revoked for the remainder of the current license or certificate year and will not be reinstated or renewed until the penalty is paid in full.

(b) The attorney general may bring an action in the name of the director in the superior court of Thurston County or of any county in which the violator may do business to collect any penalty imposed under chapter 18.160 RCW.
