To conform with the requirements of RCW 34.05.230, the department maintains a roster of interested persons who have requested in writing to the department rules coordinator, to be notified of all interpretive and policy statements issued by the department. The roster is kept in the rules coordinator's office and is updated once each year. Persons not indicating a desire to continue on the roster will be eliminated during the yearly update. Whenever the department issues an interpretive or policy statement, a copy of the statement will be sent to each person listed on the roster.
