    SAMP Near-Term Projects Environmental Review: SEPA Draft Environmental Impact Statement and Public Comment Period

    The Port of Seattle released a Draft Environmental Impact Statement (DEIS) under the State Environmental Policy Act (SEPA) for near-term construction and expansion projects at Seattle-Tacoma International Airport, finding that surface transportation would face significant impacts while noise and air quality impacts would remain within legal health standards. A 60-day public comment period runs from May 22 to July 21, 2026, with in-person meetings in SeaTac, Burien, Des Moines, and Federal Way, plus virtual options and multilingual outreach. A Final Environmental Impact Statement is expected by the end of 2026.

    Ep #27 Emergency! SAMP/SEPA DEIS (2/3)

    **Discover why environmental progress stalled for airport communities while cars got cleaner** Ever wonder why your car's emissions have dramatically improved over decades, but aviation seems stuck in the past? In this eye-opening episode of The Airport Communities Podcast, we explore the fascinating tale of two environmental paths that diverged after 1970. While Washington Senator Scoop Jackson spearheaded NEPA—one of the largest expansions of environmental policy in American history—and California secured game-changing carve-outs in the Clean Air Act that led to massive air quality improvements, aviation somehow got left behind. Despite Boeing being headquartered in Washington, aviation environmental standards never caught up. UW Meteorologist Cliff Mass delivers some stark perspective: those two annual flights to Europe generate more greenhouse gases than most people produce in their entire homes over a year. Meanwhile, Boeing's monopoly status has eliminated market incentives for cleaner technology. This wasn't an oversight—it was intentional. Today, every airport community continues paying the price for decisions made decades ago that exempted aviation from automotive-level engineering standards.

    The cities of SeaTac, Burien, and Des Moines jointly wrote to the Port of Seattle on May 18, 2026, requesting a 90-day public comment period for the Sustainable Airport Master Plan (SAMP) Draft Environmental Impact Statement. The cities cited the document's technical complexity, overlapping regional demands including 2026 FIFA World Cup preparations, summer scheduling constraints, and unresolved concerns from the prior federal environmental review as reasons more time is needed. The letter was signed by the SEPA Responsible Officials from all three cities and emphasizes that airport-related impacts on noise, air quality, transportation, and public health directly affect their communities.

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.
