The proposed bill establishes the Washington State Supply Chain Competitiveness Infrastructure Program, which aims to enhance the state's competitiveness in the global trade market by improving critical infrastructure for the transport and movement of goods. It emphasizes collaboration among various stakeholders, including public ports and tribal governments, to prioritize and implement infrastructure projects that support the supply chain. The bill also creates a dedicated account in the state treasury for this program, funded through legislative appropriations and loan repayments, focusing on projects that enhance transportation infrastructure, economic efficiency, and environmental sustainability. Additionally, the bill modifies the management of the treasury income account, clarifying that it is subject to chapter 43.88 RCW and stipulating that no appropriation is required for payments to financial institutions. It introduces the supply chain competitiveness infrastructure program account as an eligible account for receiving earnings. The bill also includes provisions to ensure that no treasury accounts or funds will receive earnings without a specific affirmative directive, and it establishes expiration dates for certain provisions on July 1, 2028, while indicating that other provisions will also take effect on that date. These changes aim to improve the clarity and efficiency of fund management within the state treasury system.
