H.R. 2533, the Sound Insulation Treatment Repair and Replacement Program Act, was introduced in April 2023 to allow airports to receive additional federal funding to repair or replace previously installed sound insulation in homes affected by aircraft noise. The bill allows the Secretary of Transportation to grant a one-time waiver so that prior government spending on a home's soundproofing does not count against the allowable project cost for new work. Homes are eligible if they fall within the FAA's DNL 65 noise standard or if an FAA-certified auditor determines that the original soundproofing caused physical damage to the residence.

The Sound Insulation Treatment Repair and Replacement Program Act, introduced in the 118th Congress by Mr. Smith of Washington, would allow airports to receive additional federal funds under the Airport Improvement Program to repair or replace previously installed sound insulation in residential homes affected by aircraft noise. The bill provides a one-time waiver so that prior government spending on a home's soundproofing would not count against the allowable project cost for new work. Eligibility is tied to whether the building falls within the FAA's Day Night Level (DNL) 65 noise standard or suffered damage from the original sound insulation treatment.

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.

Letter dated February 22, 2021 from Representatives Adam Smith (WA-09) and Katherine Clark (MA-05) to FAA Administrator Stephen Dickson urging swift implementation of the FY21 House Appropriations Report provision on the FAA sound insulation program. The letter addresses Airport Improvement Program (AIP) regulations barring airports from applying for federal funds for the same project more

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.
