This bill aims to reduce environmental and health disparities in Washington state, particularly within large port districts, by establishing a framework for environmental justice. It introduces a new chapter to Title 53 RCW, which includes definitions relevant to environmental health impacts, overburdened communities, and vulnerable populations. Key provisions require qualifying port districts to develop an environmental justice implementation plan that outlines specific goals, metrics for tracking progress, and strategies for community engagement. Additionally, by January 1, 2026, these districts must adopt a community engagement plan to ensure equitable participation from affected communities in decision-making processes.

The bill mandates that any significant port actions initiated after January 1, 2026, must undergo an assessment of their potential cumulative impacts on overburdened communities and vulnerable populations. This assessment, conducted in collaboration with the University of Washington's department of environmental and occupational health sciences, will inform an action plan to mitigate adverse effects. Furthermore, qualifying port districts are empowered to allocate funds for remediation and mitigation efforts related to environmental impacts, ensuring that resources are directed towards addressing the needs of overburdened communities. Overall, the legislation seeks to promote environmental justice and equitable resource distribution in port district activities.
