    Engrossed Second Substitute Senate Bill 5141: Environmental Justice—Various Provisions (HEAL Act)

    Washington State's Engrossed Second Substitute Senate Bill 5141, signed into law in May 2021, aims to reduce environmental and health disparities by implementing recommendations from the state's Environmental Justice Task Force. The law requires covered state agencies—including the departments of ecology, health, transportation, and others—to address the disproportionate environmental burdens faced by low-income communities and communities of color. It establishes an Environmental Justice Council and directs state programs to prioritize benefits for communities with the greatest environmental and health burdens.

    E2SSB 5141: House Bill Analysis — Reducing Environmental and Health Disparities (HEAL Act)

    Washington State Senate Bill 5141 requires several state agencies, including the departments of Ecology, Health, Transportation, and others, to incorporate environmental justice principles into their planning and decision-making processes. The bill mandates that these agencies complete environmental justice assessments for significant actions, create community engagement plans for overburdened communities, and consult with Indian tribes on decisions affecting tribal lands. An environmental justice council would be established to oversee implementation, and the Department of Health would maintain an environmental health disparities map tracking conditions across Washington communities.

    Final Bill Report: E2SSB 5141 — Washington Environmental Justice Act (HEAL Act)

    Washington State's E2SSB 5141, enacted in 2021, requires key state agencies including Transportation and Ecology to incorporate environmental justice principles into their planning and decision-making processes, with a focus on protecting overburdened communities from disproportionate environmental and health harms. Agencies must develop community engagement plans by 2022, environmental justice implementation plans by 2023, and conduct formal environmental justice assessments for significant actions such as new rules, grants, and capital investments. Note: this legislation addresses statewide environmental justice policy broadly and does not specifically address Sea-Tac Airport noise issues.

  • Airport offers a glimpse at tightening stormwater regulations

    Key takeaways Sea-Tac Airport operates under one of the strictest stormwater permits in the state. Every inch of rain that falls at Sea-Tac generates about 6 million gallons of wasterwater, according to the airport.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
