  • TSI SMPS System with Water-based CPC Model 3789 and Electrostatic Classifier

    A TSI Scanning Mobility Particle Sizer (SMPS) system is shown outdoors, consisting of a TSI Versatile Water-based Condensation Particle Counter (Model 3789) stacked above a TSI Electrostatic Classifier. The classifier display screen shows operational parameters including sheath flow, particle diameter, and DMA voltage, with the system appearing to be deployed for ambient aerosol particle size distribution measurements.

  • Outdoor air quality or environmental monitoring instrumentation

    The image shows scientific monitoring equipment installed outdoors against a stucco wall, including what appears to be a cylindrical pump or sensor unit, a white electronics enclosure, tubing, filter canisters, and a vertical inlet probe — consistent with an ambient air sampling or noise/environmental monitoring station. No visible text, logos, or labels are legible enough to identify the specific manufacturer, agency, or measurement purpose.

  • Portable sound level meter or acoustic measurement instrument with Dell laptop

    A scientific instrument with a cylindrical silver sensor column — consistent with a sound level meter or acoustic analyzer — is shown connected to a Dell laptop displaying measurement software. A label on the instrument is partially visible but not fully legible; the setup appears configured for environmental noise data collection.

  • Gas cylinder with dual-gauge regulator and CST/Berger survey rod

    A small compressed gas cylinder fitted with a dual-gauge pressure regulator and yellow tubing is visible, along with a CST/Berger brand surveying grade rod (website www.cstsurvey.com visible). The items appear to be stored on the floor of a vehicle or portable workspace.

  • Noise monitoring station equipment installation on stucco wall

    Wall-mounted technical equipment including conduit runs, a junction box, a wire mesh-covered heater or filter unit, an air flowmeter (graduated scale visible, labeled 'l/min AIR'), yellow fiber optic or signal cable, a network switch with active indicator lights, and a watermark reading 'www.cstsurvey.com' on a conduit. Configuration is consistent with an environmental or acoustic monitoring station installation.

  • Data acquisition and wireless communication equipment installation

    A wall-mounted equipment setup featuring an Advantech ADAM data acquisition module, a wireless router/gateway device with dual antennas (labeled with what appears to be 'ROC' or similar text), and various coiled sensor cables. A small shelf holds additional networking hardware and a roll of paper towel, with multiple cable runs along a PVC conduit on a textured wall.

  • Air Quality Monitoring Station with Sampling Inlets

    White instrumentation enclosures (one bearing a 'Manti-lab' or similar brand oval label) topped with mushroom-cap ambient air sampling inlets and a meteorological sensor assembly, photographed against a partly cloudy sky. A tall antenna mast and additional monitoring equipment are visible in the background near a metal utility building.

  • Outdoor Air Quality Monitoring Station with PM Samplers and Met Sensors

    A white outdoor environmental monitoring enclosure equipped with two inlet stacks (likely PM2.5 or TSP samplers), a meteorological sensor array (temperature/humidity radiation shield), a vertical antenna, and associated cabling. The station is situated on a gravel lot near corrugated metal structures, with graffiti-marked walls visible in the background.

  • Outdoor noise monitoring equipment enclosure

    A white wooden enclosure box is opened to reveal what appears to be air pump or compressor equipment with electrical connections, situated on a gravel surface. Metal conduit runs from the enclosure to a nearby structure, with a green sensor or junction box visible at the end of the conduit — consistent with noise monitoring station infrastructure.

  • Air quality or environmental monitoring station with antenna mast

    A white equipment enclosure or monitoring shelter fitted with air sampling inlet stacks, a tall antenna mast with a wind vane or lightning rod at its apex, a smaller communications antenna, and an LG air conditioning unit. The setup is consistent with an ambient air quality or meteorological monitoring station, surrounded by trees and a chain-link fence.

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.
