  • Aviation fuel uplift in the State of Washington 2018 – 2025

    Uses and impacts Aviation fuel “uplift” means fuel deliveries, which makes it a useful proxy for several aspects of airport impacts. But the fuels aircraft burn are very different, and they break down into two classes: kerosene-based (Jet-A), used by commercial jets, and gasoline-based (AvGas), used by the piston-engine aircraft common to private pilots.

    Frequency Response Curves for Audio Weighting Standards

    Graph showing gain (in dB) versus frequency (10 Hz to 100 kHz) for the four standard audio frequency weighting curves: A-weighting (blue), B-weighting (yellow), C-weighting (red), and D-weighting (black). D-weighting, used for aircraft noise measurement, shows a prominent peak of approximately +12 dB around 3–6 kHz, making it particularly relevant to aviation noise policy contexts such as Sea-Tac Airport.

    SeaTac Permanent Noise Monitors with HAWKZ8 final approach

    A map of the Seattle-Tacoma area showing numbered noise monitoring station locations (numbered 1, 15–23, 25, 28) clustered around Seattle-Tacoma International Airport (SeaTac) and extending south through Des Moines, Federal Way, and toward Milton/Fife. The stations appear to track aircraft noise corridors along what is likely the primary north-south flight path, with a dark vertical line indicating the runway centerline or flight track.

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.
