The Port of Seattle's 2023 Budget document, prepared by the Finance and Budget Departments, outlines the financial plan for Port operations including Seattle-Tacoma International Airport. The budget previously earned a Government Finance Officers Association Distinguished Budget Presentation Award for the fiscal year beginning January 1, 2022, recognizing it as an effective policy document, financial plan, operations guide, and communications tool. Note: this document covers general Port finances and does not specifically address Sea-Tac Airport noise policy.

This Port policy (AC-13) establishes standards for disposing of Port-owned property, covering items ranging from capital assets to small equipment, with the goals of saving costs, maximizing returns, and maintaining a proper audit trail. It defines when property should be disposed of — such as when it is excess, obsolete, damaged, or destroyed — and outlines the authorization requirements, including Commission approval for surplus property exceeding a set dollar threshold. Note that this policy does not address land, abandoned third-party property, or consumable supplies.

A University of Washington thesis by Mariah Dittmore investigates whether short-term exposure to ultrafine particles from aircraft engines causes measurable cardiorespiratory harm at concentrations found in surrounding communities, and whether personal protective equipment can reduce that harm. The research builds on a 2018 Los Angeles study that linked walking near aircraft pollution to elevated blood inflammation markers, while noting that roadway traffic posed its own distinct respiratory risks. The findings are relevant to policy discussions around Seattle-Tacoma International Airport and the health of workers and residents exposed to aircraft emissions.

The Worldwide Airport Slot Guidelines (WASG), Edition 2, effective July 1, 2022, is a joint publication by Airports Council International (ACI), the International Air Transport Association (IATA), and the Worldwide Airport Coordinators Group (WWACG) that provides global standards and guidance for managing airport slot allocation. The document is intended to help airports, airlines, and coordinators navigate capacity constraints and scheduling processes at busy airports worldwide. Note that while this document covers broad international slot management principles, readers should consult applicable local laws and regulations for specific airport noise or capacity policies.

A white paper by Vianair, Inc. examining noise abatement procedures at Ronald Reagan Washington National Airport (DCA) and proposing the development of a comprehensive Fly Quiet program to reduce aircraft noise impacts on surrounding residential communities.

A comprehensive list of stakeholders and their representatives for a Master Plan Stakeholder Committee, including representatives from Boeing, FAA, airlines, local government districts, education institutions, and aviation organizations. The document also includes staff and consultant information with airport directors and operations personnel.

This October 2021 progress update presents findings from a Ground Noise Study conducted at Seattle-Tacoma International Airport (SEA). The presentation covers key acoustic concepts—including Maximum Sound Level (Lmax), Sound Exposure Level (SEL), and Equivalent Sound Level (Leq)—alongside topics such as sound propagation, the study's scope of work, noise monitoring activities, and planned next steps. The study aims to better understand and document ground-level noise impacts in and around the airport.
