Wash. Rev. Code § 80.04.160 (2026)

The commission is hereby authorized and empowered to adopt, promulgate and issue rules and regulations covering the transmission and delivery of messages and conversations, and the furnishing and supply of gas, electricity, wastewater company services, and water, and any and all services concerning the same, or connected therewith; and generally such rules as pertain to the comfort and convenience of the public concerning the subjects treated of in this title. Such rules and regulations must be promulgated and issued by the commission on its own motion, and must be served on the public service company affected thereby as other orders of the commission are served. Any public service company affected thereby, and deeming such rules and regulations, or any of them, improper, unjust, unreasonable, or contrary to law, may within twenty days from the date of service of such order upon it file objections thereto with the commission, specifying the particular grounds of such objections. The commission shall, upon receipt of such objections, fix a time and place for hearing the same, and after a full hearing may make such changes or modifications thereto, if any, as the evidence may justify. The commission has, and it is hereby given, power to adopt rules to govern its proceedings, and to regulate the mode and manner of all investigations and hearings. However, no person desiring to be present at such hearing may be denied permission. Actions may be instituted to review rules and regulations promulgated under this section as in the case of orders of the commission.
