    Puget Sound Clean Air Agency: Agency Organization Chart

    This document is an organizational chart for the Puget Sound Clean Air Agency, dated September 2017, showing the agency's internal structure under Executive Director Craig Kenworthy. It outlines divisions including Compliance, Air Quality Programs, Legal/General Counsel, and support functions such as Human Resources, Finance, and Communications, along with the managers and staff assigned to each area. While the agency oversees regional air quality, this chart does not specifically address Sea-Tac Airport noise policy.

    Highway Air Toxics Impacts in the Chinatown-International District of Seattle

    This document describes a 2015–2018 air quality research project by the Puget Sound Clean Air Agency focused on measuring highway-related air toxics near Interstate 5 in Seattle's Chinatown-International District and Yesler Terrace neighborhoods. The study aimed to assess cancer risks from pollutants such as benzene, formaldehyde, and diesel particulate matter in communities identified as among the most environmentally and economically vulnerable in Washington State. While not directly related to Sea-Tac Airport noise policy, the project represents regional efforts to address transportation-related environmental health impacts on minority and low-income communities in the greater Puget Sound area.

    Air quality: Focus on Puget Sound

    This April 2004 report by the League of Women Voters examines air quality in the Puget Sound region, tracing the history of air pollution regulation from King Edward I's coal ban in 1305 through the creation of the U.S. Environmental Protection Agency in 1970. It focuses on the role of the Puget Sound Clean Air Agency in monitoring and reducing local air pollutants, with particular attention to small particles and diesel emissions. The report provides background on federal clean air legislation and outlines the League's related policy positions.

    Final report: Puget Sound air toxics evaluation

    This 2003 report by the Puget Sound Clean Air Agency evaluates air toxic chemicals in the Puget Sound region, assessing potential cancer and non-cancer health risks based on air monitoring data and EPA modeling. It identifies priority chemicals of concern, estimates human exposure levels, and draws conclusions about the health impacts of pollutants such as diesel exhaust and woodsmoke on local residents.

    EXH 445: Letter to Ecology Transmitting Synthetic Minor Permit and PSCAA Order No. 7777 STIA Air Emissions

    In September 1999, the Puget Sound Clean Air Agency issued an order limiting facility-wide air emissions of sulfur dioxide, nitrogen oxides, and carbon monoxide at Seattle-Tacoma International Airport to less than 99 tons each per any 12-month period. The Port of Seattle is required to monitor fuel usage, calculate monthly emissions using specified factors, and maintain rolling records for at least five years. A March 2001 letter from the Port's Environmental Program Manager confirms emissions were well within limits, with nitrogen oxides typically running 15–17 tons and both carbon monoxide and sulfur dioxide at 10 tons or less over the previous 12-month period.

    EXH 444: Email Ann Kenny (Ecology) to Elizabeth Leavitt Requesting CZM Documentation

    In this March 20, 2001 email, Ann E. Kenny, a Senior Permitting Specialist at the Washington Department of Ecology, contacts Elizabeth Leavitt while working on a three-month Coastal Zone Management (CZM) status letter. Kenny requests copies of two key documents: a shoreline exemption letter issued by the City of Auburn on 8/9/00, and air quality compliance documentation including a Governor's Certification from 6/30/97 and a PSCAA permit from 9/21/99.

    Addressing community health concerns around SeaTac Airport: Response to the question, ‘Is it possible to monitor jet engine exhaust emissions or to model their path using data on prevailing winds and takeoff patterns?’

    This March 2000 report, prepared by Washington State health and environmental agencies, addresses community health concerns about air quality around Seattle-Tacoma (Sea-Tac) Airport by examining whether jet engine exhaust emissions can be monitored or modeled using wind and takeoff data. It outlines recommendations for conducting a comprehensive air quality study, including monitoring methods, data analysis approaches, and estimated costs, while also considering health impacts and environmental justice issues for nearby residents. The report was developed in consultation with public health officials, community representatives, the EPA, and local universities.

    This March 2000 report, prepared by Washington State health and environmental agencies, examines whether jet engine exhaust emissions from Seattle-Tacoma International Airport can be monitored or modeled using wind and takeoff data. It reviews previous air quality studies, outlines health and environmental justice concerns for nearby communities, and recommends a structured air quality monitoring study with specific methods, data analysis approaches, and estimated costs. The report was developed in consultation with community representatives, the EPA, and local universities.

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.
