The Administrative Procedure Act, chapters 34.05 RCW and 10-08 WAC apply to all adjudicative proceedings under the jurisdiction of the board.

Administrative review is performed by one of the following types of adjudicative proceedings:

(1) A formal adjudicative hearing before the entire board with the presentation of witness testimony and/or documentary evidence; or

(2) A brief adjudicative proceeding (BAP) before a single presiding officer, which may be used for the review of simple matters where no witness testimony is needed.

(3) An emergency adjudicative proceeding under RCW 34.05.479, which may be used when there is an immediate danger to the public health, safety, or welfare requiring immediate board action.
