This chapter implements RCW 34.05.210 and 34.05.310 through 34.05.395, the provisions of the Administrative Procedure Act on agency rule making. It also implements chapter 34.08 RCW, the State Register Act. It replaces the former chapters 1-12 and 1-13 WAC on drafting and filing of notices and rules. It covers both institutions of higher education and all other administrative agencies, since chapter 34.05 RCW merged chapters 28B.19 and 34.04 RCW.
