Wash. Rev. Code § 80.36.310 (2026)

(1) Telecommunications companies may petition to be classified as competitive telecommunications companies under RCW 80.36.320 or to have services classified as competitive telecommunications services under RCW 80.36.330. The commission may initiate classification proceedings on its own motion. The commission may require all regulated telecommunications companies potentially affected by a classification proceeding to appear as parties for a determination of their classification.

(2) Any company petition or commission motion for competitive classification shall state an effective date not sooner than thirty days from the filing date. The company must provide notice and publication of the proposed competitive classification in the same manner as provided in RCW 80.36.110 for tariff changes. The proposed classification shall take effect on the stated effective date unless suspended by the commission and set for hearing under chapter 34.05 RCW or set for a formal investigation and fact-finding under RCW 80.36.145. The commission shall enter its final order with respect to any suspended classification within six months from the date of filing of a company's petition or the commission's motion.
