The bill establishes a voluntary donation system for vessel owners to contribute to a newly created Sea Lion Predation Control Account during the vessel registration process, with the aim of preserving salmon populations in the lower Columbia River area. Vessel owners will have the option to donate $1 or more when registering or renewing their vessel registration, and these contributions are entirely voluntary. The funds collected will be allocated to managing pinniped populations to support salmon preservation efforts. Additionally, the bill amends existing laws related to the treasury income account to ensure that the Sea Lion Predation Control Account receives a share of earnings based on its average daily balance, while also clarifying that these funds cannot replace existing financial support for pinniped management from other state agencies.

Furthermore, the bill outlines the management and distribution of earnings from the treasury income account, specifying that no appropriation is required for payments related to banking services or refunds mandated by federal law. It mandates monthly distributions of earnings to the general fund and other specified accounts, including the newly added Sea Lion Predation Control Account. The bill also emphasizes compliance with federal regulations and state constitutional requirements, ensuring that any state agency with independent authority over accounts not required to be held in the state treasury can receive its proportionate share of earnings. Overall, the bill aims to streamline the financial management of state treasury accounts while supporting conservation efforts for salmon populations.
