Airports Council International-North America (ACI-NA) submitted comments to the FAA in October 2022 opposing a draft policy that would impose new federal review and approval processes on how airports can use land that was federally acquired or conveyed. ACI-NA argued the policy is confusing, could lead to inconsistent decisions across FAA regional offices, and may delay airport development projects and increase costs. The organization urged the FAA to grandfather existing land use designations, clarify key undefined terms, and work collaboratively with airports to revise the policy.

This FAA document outlines the legally binding assurances that airport sponsors must agree to when accepting federal grant funds for airport development, planning, or noise compatibility programs. Sponsors certify compliance with a broad range of federal laws, executive orders, and regulations—including civil rights, environmental, and labor standards—for the duration of the project's useful life, which can extend up to 20 years. Certain obligations, such as those related to exclusive rights, airport revenue, and real property acquired with federal funds, have no expiration as long as the airport remains in operation.

The FAA announced a Notice of Funding Opportunity for an Airport Environmental Mitigation Pilot Program, authorized under Section 190 of the FAA Reauthorization Act of 2018, which provides grants of up to $2.5 million per project to help public-use airports measurably reduce aviation impacts on noise, air quality, or water quality within five miles of the airport. Up to six projects may be funded, with costs split 50/50 between federal and airport matching funds, and projects must be carried out by an eligible consortium of businesses, educational or research organizations, government entities, or federal laboratories. Pre-applications were due by July 9, 2021, and priority was given to projects achieving the greatest reductions in aircraft noise, emissions, or water quality impacts.

The National Plan of Integrated Airport Systems (NPIAS) 2021–2025 is a federal planning document published by the U.S. Department of Transportation's Federal Aviation Administration on September 30, 2020. It outlines the nation's airport infrastructure needs and investment priorities for a five-year period under Title 49 U.S. Code, Section 47103. While it covers the broader national airport system, it provides context for understanding federal aviation policy that can influence noise management decisions at airports like Sea-Tac.

FAA Order 5090.5, effective September 3, 2019, establishes guidelines for managing the National Plan of Integrated Airport Systems (NPIAS) and the Airports Capital Improvement Plan (ACIP), which together identify airports important to national air transportation and prioritize federal funding for airport development projects. The order serves as a financial planning tool for systematically assigning Airport Improvement Program (AIP) funds to qualifying airports across the country. Note that this document addresses broad national airport capital planning policy and does not contain specific provisions related to Sea-Tac Airport noise mitigation or local noise policy.

The FAA's Airport Improvement Program (AIP) Grant Histories page provides access to annual summaries of federal airport grants dating back to 2006, organized by fiscal year and available in both PDF and MS Excel formats. Users can look up grant histories for individual airports included in the National Plan of Integrated Airport Systems (NPIAS) using an online tool. While this resource covers AIP funding across all U.S. airports, it may be referenced when researching federal grants awarded to Seattle-Tacoma International Airport for noise mitigation and other improvement projects.

This Airports Council International – North America (ACI-NA) report, covering 2019–2023, examines the gap between what U.S. airports need to spend on infrastructure and the funding currently available to them. It estimates total development costs by airport size, project type, and location, and compares ACI-NA findings with FAA projections. The report highlights growing pressures from rising construction costs, increasing passenger and cargo demand, and insufficient federal funding mechanisms.
