Increasing environmental justice by improving government decisions.

HB 1303 requires Washington state agencies to formally consider environmental justice in government decisions affecting communities disproportionately burdened by pollution. It mandates the Department of Ecology to add environmental justice as a standard element in environmental checklists and rules, and to develop standardized mitigation measures for adverse impacts on these communities. The bill directly affects lead agencies (like state departments) conducting environmental reviews under Chapter 43.21C RCW, requiring them to integrate environmental justice considerations alongside other environmental factors. This builds on existing environmental justice law (RCW 70A.02) without changing its core requirements. The policy change ensures agencies systematically address health and environmental disparities in their decision-making processes.
