Senate Bill 5987 adds a new section to chapter 47.20 RCW, amends RCW 70A.65.260, declares the April 22, 2025 Fairfax bridge failure an emergency, and takes effect immediately. It directs the (unnamed) department to restore access on State Route 165 across the Carbon River as soon as possible and gives the (unnamed) secretary emergency authority to expedite planning and construction of a Fairfax bridge replacement. That emergency authority includes the power to waive or suspend specified statutory obligations or limitations to speed work, but waivers are prohibited where they would conflict with federal conditions for federal funds or with First Amendment rights. The secretary must give as much notice as practical to the governor, legislative transportation committee leaders, and impacted local governments when issuing orders under the new section, and activities implementing the new section are excluded from Executive Order 25-07. The amendment to RCW 70A.65.260 revises eligible uses and restrictions for the climate commitment account, specifies that moneys may be spent only after appropriation and must fund projects physically located in Washington, and authorizes certain appropriations across specified biennia. The legislature intends to dedicate at least $50,000,000 per biennium for subsection (1)(m) to support tribal mitigation and adaptation; it may appropriate account funds for environmental justice activities in 2023-2025 and 2025-2027; and it may provide full funding in 2025-2027 and 2027-2029 for emergency replacement of infrastructure on SR 165 described as caused by failure to adequately address climate impacts. Type of legal change: creation of a new statutory emergency authority and procedural change to allow suspension of some statutory requirements, a substantive amendment to the climate commitment account statute specifying eligible uses and appropriation authorizations, and an immediate-effect emergency declaration. The bill does not create new criminal offenses or change penalties. Important context is missing: the text here does not identify which specific agency is "the department" or which office is "the secretary," it does not include the contents of Executive Order 25-07 or the external statutes cited, and the phrase "caused by failure to adequately address the impacts of climate" is not further defined in the provided excerpts.

If enacted, the bill treats the April 22, 2025 failure and permanent closure of the Fairfax Bridge as an emergency and directs the state to restore access on SR 165 across the Carbon River as soon as possible. It gives the department and the secretary (not explicitly identified in the provided text) emergency authority to speed planning and construction of a replacement bridge and to waive or suspend many statutory requirements to accelerate work, except where doing so would conflict with federal funding conditions or First Amendment protections. The secretary must give as much notice as practical to the governor, transportation legislative leaders, and impacted local governments, and the expedited activities are not subject to Executive Order 25-07. The bill also changes how the climate commitment account can be used, allowing the legislature to appropriate money in the 2025-27 and 2027-29 biennia for emergency SR 165 replacement and directing at least $50 million per biennium toward tribal mitigation and adaptation support; however, money can only be spent after appropriation and projects must be located in Washington. In practical terms, the state transportation authority and elected officials will likely shoulder expedited planning and construction responsibilities and state budgets may be tapped to cover emergency replacement costs, while local governments, tribes, utilities, and workers in the area may see faster timelines and altered regulatory processes. It is unclear from the provided text which exact office is empowered, which specific statutes may be waived, and how the phrase about failures to address climate impacts will be applied.
