The FAA's National Plan of Integrated Airport Systems (NPIAS) 2019–2023 is a report to Congress that outlines the federal government's framework for developing and maintaining a national network of airports eligible for federal funding. It covers planned airport infrastructure investments across the United States over a five-year period. While the report addresses airports nationwide, it does not specifically focus on noise policy or Sea-Tac Airport.

This document from the FAA's National Plan of Integrated Airport Systems (NPIAS) 2023-2027 defines the categories and roles of U.S. airports, ranging from large commercial hubs to small general aviation fields, based on criteria such as annual passenger enplanements, flight operations, and cargo weight. It outlines how airports are classified as Primary (Large, Medium, Small Hub, or Nonhub) or Nonprimary (National, Regional, Local, Basic, or Unclassified), and identifies the 3,287 airports that make up the national airport system. The document also details the data sources used by the FAA to determine each airport's classification and role within the system.

Appendix B of the National Plan of Integrated Airport Systems (NPIAS) 2023-2027 provides national and state maps showing the locations of all 3,287 existing NPIAS airports across the United States and its territories, including Alaska, Hawaii, Puerto Rico, Guam, and American Samoa. Airports are categorized by type — Large/Medium hub, Small/Nonhub, National/Regional, Local/Basic, and Unclassified — and displayed alongside Metropolitan and Micropolitan Statistical Areas. Note that this document covers the broader national airport system and does not contain specific noise policy information related to Sea-Tac Airport.

This document is Appendix A of the FAA's National Plan of Integrated Airport Systems (NPIAS) for 2021-2025, which lists airports across the U.S. along with their ownership, category, and 5-year development cost estimates for federally eligible improvements. It defines key terms such as airport categories (Commercial Service, Reliever, and General Aviation), hub classifications based on passenger enplanements, and based aircraft counts. The data was primarily compiled in 2019 and does not reflect changes in airline activity due to the COVID-19 pandemic.

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.

In September 2018, the FAA submitted the National Plan of Integrated Airport Systems (NPIAS) 2019–2023 report to Congress, identifying 3,340 airports important to national air transportation and estimating $32.5 billion in eligible infrastructure development needs over that five-year period. The report, required by federal law every two years, covers topics including safety, capacity, environmental conditions, runway pavement condition, and financial performance of the national airport system. While this document focuses on broad national airport planning and funding, it does not specifically address noise policy at Seattle-Tacoma International Airport.

The Northwest Mountain Regional Airport Plan (RAP) 2012 outlines the FAA's priorities for airport system development across the Northwest Mountain Region, covering safety improvements, runway upgrades, and investment strategies for 136 focus airports. The plan addresses key initiatives such as runway safety areas, wildlife hazard assessments, and preparation for NextGen technologies, with funding decisions guided by a regional Board of Directors overseeing the Airport Improvement Program. Note that this document covers regional airport planning broadly and does not specifically address Sea-Tac Airport noise policy.
