The bill amends the Revised Code of Washington (RCW) to enhance safety and accountability in excavation practices related to underground facilities. It introduces key definitions such as "Hard Surface," which refers to areas covered with impervious materials, and "Positive Response," indicating that facility owners have completed the necessary marking or information provision about underground facilities. The bill clarifies the responsibilities of excavators and facility operators, mandating that excavators mark the excavation area with white lining or pin flags and establish a timeline for notifying facility operators through a one-number locator service. It also emphasizes the importance of maintaining accurate markings and outlines the liability for damages resulting from non-compliance.

Additionally, the bill establishes a safety committee composed of thirteen members from various sectors, including local governments, utilities, and contractors, appointed for staggered three-year terms. This committee is tasked with meeting quarterly to review complaints regarding violations related to underground facilities, although it does not have the authority to resolve disputes between facility operators and excavators. The committee can provide written notifications to the commission about potential violations and recommend remedial actions, which may include penalties or educational initiatives aimed at improving public safety.
