Under RCW 34.05.312, each agency must designate a rules coordinator. The agency and mailing address of the rules coordinator must be submitted for publication in the Washington State Register at the time of designation and maintained thereafter on the office of the code reviser's website for the duration of the designation. To submit a new designation or make changes to an existing designation, send a Word document (preferably on the agency letterhead) to the electronic filing system or send the original and three copies to the office of the code reviser. An agency may use the template found on the office of the code reviser's website at http://leg.wa.gov/CodeReviser/Pages/Washington_State_Register.aspx.
