(1) Pursuant to RCW 47.42.120, after hearing the department may revoke a permit without refund for any of the reasons following:

(a) For making any false or misleading statement on an application for a new permit or during the annual permit renewal certification process, whether or not the statement is material to or relied upon by the department in issuing or renewing the permit; and when such false or misleading statement remains uncorrected after the expiration of thirty days following written notice thereof.

(b) For allowing a sign to remain in a condition of disrepair or unreasonable state of repair after the expiration of thirty days following written notification thereof.

(c) For maintaining a sign, for which a permit has been issued, in violation of any provision of the act or these regulations after the expiration of thirty days following written notice thereof.

(d) For any convictions of a violation of the act or any of these regulations, any permit held by the convicted person may be revoked after the expiration of thirty days following written notice thereof whether or not such violation is related to the sign for which the permit is revoked.

(e) For allowing a sign to remain after it has become abandoned, destroyed or discontinued, as defined in WAC 468-66-010, following written notice thereof. For abandoned or destroyed signs, the department will revoke the permit after the expiration of thirty days following written notice thereof. For discontinued signs, the department will cease permit revocation proceedings if the sign owner places advertising content on the sign within ninety days following written notice thereof.

(2)(a) Any written notice referenced in subsection (1) of this section shall be sent by first class mail, postage prepaid, to the permittee at their last known address on file with the department; and the permittee's receipt of said notice shall be deemed the third day after mailing.

(b) If the permittee does not comply with the written notice within thirty days, the department shall conduct a hearing, revoke the permit, and send written notice of the permit revocation to the permittee. Upon permit revocation the sign will become an illegal sign, and the department will initiate proceedings as authorized by RCW 47.42.080 to remove the illegal sign. Review of the department's action shall be in compliance with RCW 47.42.060.
