The City of Des Moines, WA is purchasing $124,191 worth of Bird-X bird deterrent balls to cover a 32,000-square-foot stormwater detention pond at the Des Moines Creek Business Park, after the Port of Seattle notified the city in 2023 that the pond was out of compliance with FAA wildlife hazard standards. FAA Advisory Circular 150/5200-33C requires physical barriers on stormwater ponds near public-use airports—such as Seattle-Tacoma International Airport—when standing water persists longer than 48 hours and poses a risk of attracting hazardous wildlife that could interact with aircraft. The City Council approved the purchase on November 21, 2024, with costs funded through the Surface Water Management Maintenance Fund.

A September 2024 U.S. Government Accountability Office report found that the FAA's air traffic control systems are critically outdated, with 37% rated unsustainable and 39% potentially unsustainable out of 138 total systems reviewed. The agency has been slow to modernize the most at-risk systems, with some upgrades not planned for completion until 2030–2035, and four critical systems lacking any modernization plans at all. The GAO made seven recommendations to improve FAA oversight and accelerate upgrades to protect the safety and efficiency of the national airspace.

The Aviation Environmental Design Tool (AEDT) Version 3g is a Federal Aviation Administration software system used to model aircraft operations and calculate their environmental impacts, including noise, emissions, and fuel consumption. This Quick Start Tutorial guides users through building basic noise and emissions studies, covering steps such as adding airports, creating flight tracks, setting up receptors, and running metric results. The tool is relevant to airport noise policy analysis, as it provides a structured method for quantifying and evaluating the environmental effects of aviation activity around airports like Sea-Tac.

This is a U.S. Senate Appropriations Committee report from July 2024 recommending passage of the Transportation, Housing and Urban Development, and Related Agencies Appropriations Bill for fiscal year 2025, totaling approximately $98.7 billion. The bill covers funding for federal agencies including the Federal Aviation Administration, Federal Highway Administration, Federal Transit Administration, and the Department of Housing and Urban Development, among others. It represents an increase of roughly $1.25 billion over 2024 appropriations levels.

14 CFR Part 161 sets out the federal rules governing how airports like Sea-Tac must notify the public and obtain FAA approval before imposing noise and access restrictions on aircraft operations. It covers different requirements depending on whether restrictions apply to older Stage 2 aircraft or newer Stage 3 aircraft, including mandatory analysis, public comment periods, and formal FAA review. Airports that fail to follow these procedures risk losing federal grant funds and passenger facility charges.

This federal regulation identifies certain U.S. airports as 'high density traffic airports' and sets hourly limits on the number of IFR (instrument flight rules) takeoffs and landings allowed there. The designated airports include LaGuardia, Newark, O'Hare, Ronald Reagan National, and John F. Kennedy, with specific caps assigned to air carriers, commuter airlines, and other users. Note that this regulation does not apply to Sea-Tac Airport and pertains to air traffic slot management rather than noise policy.
