(1) You must send your request to vacate an order to OAH or BOA twenty-one calendar days after the date the order of dismissal was mailed to you. If no request is received within that deadline, the dismissal order becomes a final order.

(2) You may make a late request to vacate the order of dismissal for up to one year after it was mailed but you must show good cause according to WAC 388-02-0020 for the late request to be accepted and the dismissal to be vacated.

(3) If you ask to vacate more than one year after the order was mailed, the ALJ may vacate the order of dismissal if the DSHS representative and any other party agrees to waive (excuse) the deadline.
