Wash. Rev. Code § 81.28.050
Unless the commission otherwise orders, a change may not be made to any classification, rate, fare, charge, rule, or regulation filed and published by a common carrier subject to regulation by the commission as to rates and service, except after thirty days' notice to the commission and to the public. In the case of a solid waste collection company, a change may not be made except after forty-five days' notice to the commission and to the public. The notice must be published as provided in RCW 81.28.040 and must plainly state the changes proposed to be made in the schedule then in force and the time when the changed rate, classification, fare, or charge will go into effect. All proposed changes must be shown by printing, filing, and publishing new schedules or must be plainly indicated upon the schedules in force at the time and kept open to public inspection. The commission, for good cause shown, may by order allow changes in rates without requiring the notice and the publication time periods specified in this section. When any change is made in any rate, fare, charge, classification, rule, or regulation, attention must be directed to the change by some character on the schedule. The character and its placement must be designated by the commission. The commission may, by order, for good cause shown, allow changes in any rate, fare, charge, classification, rule, or regulation without requiring any character to indicate each and every change to be made.
During a state of emergency declared under RCW 43.06.010(12), the governor may waive or suspend the operation or enforcement of this section or any portion of this section or under any administrative rule, and issue any orders to facilitate the operation of state or local government or to promote and secure the safety and protection of the civilian population.
