Wash. Rev. Code § 19.122.027 (2026)

(1) The commission must establish a single statewide toll-free telephone number to be used for referring excavators to the appropriate one-number locator service. The one-number locator service shall maintain a web-based platform that provides the same services as the toll-free telephone number online. The web-based platform must meet the requirements outlined in RCW 19.122.030 (1) and (2). The web-based platform must be free of charge to those requesting location of underground facilities and operated in the same manner as the toll-free telephone number. The one-number locator service must require that an excavator provide a work-to-begin date in the notice. The one-number locator service must allow an option for the submission of a notice that generates multiple unique and individual excavation confirmation codes in accordance with RCW 19.122.030(1). This notice option does not alter any duties, obligations, or liabilities of excavators or facility operators.

(2) The commission, in consultation with the entity administering the one-number locator service, must establish minimum standards and best management practices for one-number locator services.

(3) One-number locator services must be operated by nongovernmental agencies.

(4) All facility operators within a one-number locator service area must subscribe to the service.

(5) Failure to subscribe to a one-number locator service constitutes willful intent to avoid compliance with this chapter.
