A legal and regulatory analysis arguing that the FAA must conduct a broader cumulative environmental impact review of Seattle-Tacoma International Airport expansion, following a 9th Circuit Court ruling that remanded the 'Burien Turn' flight path back to the FAA. The document contends that multiple airport expansion projects—including the addition of 14 new gates and the extension of Highway 509—were each approved individually under categorical exclusions (CATEXs) without properly accounting for their combined effects on noise, air quality, and environmental justice communities. The author argues that under NEPA regulations, the FAA is required to analyze these past, present, and future actions together to determine whether their collective impact is significant.

This document presents a point-by-point rebuttal to an FAA 'Limited Update' regarding a new flight departure procedure at Seattle-Tacoma International Airport, arguing that the FAA has failed to conduct required safety risk analyses, properly assess cumulative noise and air quality impacts on environmental justice communities, and comply with court-ordered environmental review under NEPA. The authors contend that the FAA is understating the scope and timeline of the Sea-Tac Airport Master Plan (SAMP) expansion while dismissing significant health, noise, and emissions impacts on nearby residents. The critique calls out procedural shortcuts, incomplete public comment responses, and what it characterizes as predetermined conclusions designed to avoid full environmental scrutiny.

Washington Governor Jay Inslee signed Executive Order 23-02 on November 15, 2023, requiring all state executive agencies to create plain language policies to make public documents easier to understand. Agencies must prioritize rewriting their most-used public forms and documents, and the Department of Enterprise Services will provide plain language training for state employees by June 30, 2024. The order aims to ensure all Washingtonians, including non-native English speakers, can access and understand government information.

A public comment submitted to the Department of Transportation argues that communities should have a stronger voice in shaping Advanced Air Mobility (AAM) policy, including drones and air taxis, before decisions are made. It calls on the FAA to conduct independent research on noise, health, environmental, and privacy impacts, and to use better noise measurement tools that reflect residents' real-world experience. The comment also urges regulators to avoid repeating mistakes made during the NextGen rollout, where communities were excluded from the process until after key decisions had already been implemented.

The FAA is reviewing its civil aviation noise policy, which is based on decades-old research, to better address how aircraft noise affects communities near airports like Sea-Tac. The review examines noise measurement systems, acceptable noise thresholds, and the impact of aviation noise on residents—including annoyance, sleep disturbance, and health effects. Public and stakeholder input is being sought to help modernize the policy.

This U.S. Army Corps of Engineers Record of Decision evaluates a permit application from the Port of Seattle (case 1996-4-02325) for construction work in the Seattle area, assessing environmental impacts including effects on wetlands, fish habitat, water quality, air quality, and noise. The document reviews compliance with numerous federal and state laws—such as the Clean Water Act, Endangered Species Act, and National Environmental Policy Act—and addresses public and agency concerns, including those related to airport and aircraft safety. It ultimately documents the Corps' findings and determinations regarding whether to issue, conditionally issue, or deny the requested permit.

This document classifies and describes the various wetland types found within the Sea-Tac Airport project area, using both the Cowardin (1979) and Hydrogeomorphic (HGM) classification systems. It identifies forested, scrub-shrub, emergent, aquatic bed, and riverine wetlands across three drainage basins — Miller Creek, Des Moines Creek, and Walker Creek — listing the specific wetland units belonging to each category. The classifications support environmental impact assessment and mitigation planning associated with airport development activities.

In August 2022, the FAA revised its internal guidance on Section 163, most notably changing how it defines a 'project' so that if any part of a development requires FAA approval, the agency retains authority over the entire project — limiting airports' ability to break larger efforts into smaller pieces to avoid oversight. The FAA also proposed a new land use policy in September 2022 governing how airport sponsors may use federally acquired or conveyed airport land for non-aeronautical purposes, identifying four categories of land use that determine when FAA approval is required. Airport sponsors were encouraged to submit comments on the proposed land use policy before October 17, 2022.

This guide explains how airports can pursue non-aeronautical development under Section 163 of federal aviation law, with a 2022 update covering key FAA policy changes. The update clarifies that if any part of a development project requires FAA approval, the agency now claims approval authority over the entire project — limiting a previous practice of splitting projects into smaller pieces to bypass oversight. It also covers a proposed FAA land use policy affecting how airports may lease or repurpose federally acquired or grant-funded airport land for non-aviation uses.
