    How a Senate chairman’s retaliation harmed ferries | Opinion

    This may not appear to have much to do with the airport. It is extremely unusual for any WA state elected representative to express frustration someone in their own party--particularly someone as powerful as <a href="https://senatedemocrats.wa.gov/liias/">Senator Marko Liias (D) 21st LD</a>. But Democrats have had control of the legislatures so long it is inevitable that cracks will occur. We applaud any legislator with the courage to speak out in what has become a monoculture. In Washington, there are three independent budgets. As chair of the Senate Transportation Committee, Senator Liias controls one of them, billions of dollars in funding, not only for the ferry system, but also aviation fuels. One of his priorities is Sustainable Aviation Fuel (SAF), a greenwashing distraction strongly supported by the Port of Seattle. There are ongoing plans to spend hundreds of millions of dollars in SAF processing facilities in and around his district. But despite promises from Alaska, United, and Delta, to achieve 10% usage by 2030, as of 2026 not one gallon of SAF has been used at Sea-Tac Airport.

    Fast shipping is increasing emissions. Here’s why delivery has become more polluting

    By AYA DIAB It feels simple: You shop, find something you want and click to buy. It shows up today, overnight or tomorrow. We’ve gotten used to that speed. But that convenience comes with a climate cost. Multiple factors shape the environmental toll of a delivery. These include the distance from a fulfillment center, whether

    RCW 47.06.140: Transportation facilities and services of statewide significance—Level of service standards

    RCW 47.06.140 defines transportation facilities and services of statewide significance in Washington State, including highways, the interstate system, ferry routes, freight railroads, and high-capacity transit systems, while explicitly excluding airport facilities and services from this designation. The law requires the Washington State Department of Transportation to set level of service standards for state highways and ferry routes, in consultation with local governments, while retaining final decision-making authority. Improvements to these statewide facilities are classified as essential state public facilities under RCW 36.70A.200.

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.

Read This!

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.
