Slide 22 from a Port of Seattle presentation on the Sea-Tac Airport Master Plan (SAMP) Near-Term Projects (NTPs), summarizing Environmental Justice findings using WADOH's Environmental Health Disparities Map and the Port's Equity Index. The findings conclude that the SAMP NTPs would not substantially contribute to any analyzed factors and pose no significant adverse impacts to environmental justice communities, accompanied by a study area map covering SeaTac, Burien, Des Moines, Normandy Park, and surrounding cities.

Slide 21 from a Sea-Tac Airport presentation outlines noise impact reduction measures, covering Construction (adherence to Port's Construction General Requirements, State of Washington, and City of SeaTac BMP requirements) and Operations (Fly Quiet Incentive Program, Late Night Noise Limitation Program, restrictive Aircraft Engine Runups, and Part 150 programs past and present).

Slide 20 from a Sea-Tac Airport presentation summarizing a literature review on aviation noise and human health. Key findings note that aircraft noise exposure can affect annoyance and sleep disturbance (with no regulatory standard) and that broad-scale aviation-focused health studies are lacking.

A presentation slide titled 'Climate Impact Reductions' outlining two categories of greenhouse gas mitigation measures: Construction (implementing Best Management Practices including equipment maintenance, minimizing idling, and equipment specifications) and Operations (pre-conditioned air, ground power, electric ground support equipment, renewable natural gas, alternative fuel vehicles, and public alternative transportation strategies). No specific organization logo or date is visible, though the slide numbering (19) and subject matter are consistent with an airport environmental or EIS presentation context.

A presentation slide titled 'Climate Updates' describes methodology adhering to Commission Resolution No. 3650, with a new SEPA analysis calculating GHG emissions and assessing facility risk. Findings show a modest emissions increase (2.1% by 2032, 7.7% by 2037) and no large-scale risks to Port facilities identified.

A presentation slide summarizing a literature review on health effects from ultrafine and ultra-ultrafine particulate matter. Findings state that current science does not support independent causal ultrafine particulate effects on human health, and notes a lack of broad-scale, multi-year epidemiological studies on aviation emissions.

A presentation slide titled 'Outreach and Engagement' outlining communication strategies including use of plain language, multiple communication tools (website, email, community meetings), removing participation barriers via translation tools in ten languages, and partnering with community leaders and community-based organizations. No specific organization logo or date is visible, though the content and style are consistent with a public agency engagement plan.

Slide 26 from a Sea-Tac Airport noise-policy presentation detailing the public engagement timeline: a 30-day public notice issued April 22, a 60-day public comment period from May 22 through July 21, and four public meetings held June 22 (SeaTac), June 23 (Des Moines), June 25 (Federal Way), and June 27 (Burien).

This project timeline slide shows the environmental review schedule for what appears to be a Sea-Tac Airport noise or development project, marking the current position at the Draft SEPA EIS Publication date of 5/22/26. Key milestones include the Final NEPA FEA & Decision (9/26/25), a 60-day public review period, Final SEPA EIS & Decision in Q4 2026, and a 21-day appeal period, culminating in Commission Action Required for NTP(s) approval in 2027.

Slide 24 from a Sea-Tac Airport environmental review presentation covering the Sustainable Airport Master Plan (SAMP) Near-Term Projects (NTPs). It states the methodology for cumulative impact analysis and finds that the SAMP NTPs, combined with past, present, and reasonably foreseeable future projects, would not result in significant cumulative environmental impacts.
