    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.

    Washington Action Plan—FAA Policy Concerning Airport Revenue—2021 Update

    The Washington State Department of Revenue submitted this 2021 report to the Legislature updating the state's action plan regarding Federal Aviation Administration (FAA) policy on airport revenue. The FAA requires that any state or local taxes on aviation fuel enacted after December 30, 1987—including the hazardous substance tax, petroleum products tax, and local sales and use taxes—be spent exclusively on airport and aviation purposes. The report also recommends a method for separately tracking the amounts collected from these taxes on aviation fuel, developed in consultation with the Washington State Department of Transportation's Aviation Division.

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.
