The bill is a memorial from the Washington State Legislature urging Congress to amend the Marine Mammal Protection Act to provide greater flexibility for states and tribes in managing pinniped populations, particularly in relation to the recovery of endangered salmon stocks. It highlights the success of previous lethal removal efforts of sea lions on the Columbia River, as authorized by the Endangered Salmon Predation Prevention Act of 2018, and emphasizes the findings of the Washington State Academy of Sciences, which identified pinniped populations as a significant factor in the decline of salmon populations.

The memorial calls for the expansion of adaptive management tools, including lethal removal, to be applicable across all marine shorelines and the Puget Sound, rather than being limited to the current segment of the Columbia River. The resolution requests that copies of the memorial be sent to key federal officials, including the President of the United States and leaders of the Environmental Protection Agency and the National Oceanic and Atmospheric Administration, to advocate for the proposed changes in federal law.
