Tagenvironmental assessment(33)

This appendix from a 2012 Environmental Assessment documents the published arrival flight procedures at Seattle-Tacoma International Airport that would be affected by proposed changes to how aircraft approach the airport. It includes detailed charts for routes such as the JAWBN Three Arrival and Olympia Seven Arrival, showing waypoints, altitudes, and speed restrictions for aircraft arriving from various directions including Canada and southern Washington. These procedures define the flight paths aircraft must follow when descending into Sea-Tac, directly influencing the noise experienced by communities surrounding the airport.

This November 2012 Federal Aviation Administration report evaluates the environmental impacts of proposed new arrival flight procedures at Seattle-Tacoma International Airport, part of the 'Greener Skies Over Seattle' initiative. It includes detailed appendices covering noise modeling, effects of aircraft noise on communities, historic and endangered species considerations, and agency coordination records. The goal of the proposed procedures was to reduce fuel consumption and emissions while assessing changes in noise exposure for surrounding neighborhoods.

ICAO good practice case study documenting the US/FAA NextGen ‘Greener Skies over Seattle’ initiative — a Final Environmental Assessment (FEA) completed November 1, 2012 for proposed PBN arrival procedures (STARs and RNP with Optimized Profile Descents) at Seattle-Tacoma International Airport (KSEA/Sea-Tac Airport). Collaborative project between FAA, Alaska Air Group (Alaska Airlines, Horizon Air), The Boeing

FAA Draft Environmental Assessment (EA), Volume 2 Appendices, for the Greener Skies Over Seattle project proposing new arrival procedures to Seattle-Tacoma International Airport (Sea-Tac Airport / KSEA), dated 31 October 2012. Appendices cover noise metrics (DNL, SEL, Leq, dBA), NIRS noise modeling technical report, aircraft operations and flight tracks, runway utilization, meteorological conditions, historic resource

This Washington State Department of Ecology publication, authored by Stewart M. Lombard and Cliff J. Kirchmer and released in February 2001, provides guidelines for preparing Quality Assurance Project Plans (QAPPs) for environmental studies. It outlines standards and procedures to ensure that data collected during environmental investigations meets defined quality and reliability requirements.

Email chain (AR 018453) among Erik Stockdale, Tom Luster (Ecology, tlus461@ecy.wa.gov), and Michelle Avolio (FAA, Michelle.Avolio@faa.gov) regarding the proposed SeaTac TRACON project. Avolio’s April 17, 2000 email to Luster describes FAA planning for an Environmental Assessment (EA) and Biological Assessment (BA) for DOE review and comment, contact with NMFS regarding EA/BA section contents, and discussions

This 1990 Final Environmental Assessment, prepared by the FAA's Air Traffic Division in Seattle, evaluates proposed changes to arrival and departure flight routes at Seattle-Tacoma International Airport. The document was signed by Air Traffic Division Manager Temple H. Johnson, Jr. on March 27, 1990, and examines the potential environmental impacts of rerouting aircraft traffic in and out of Sea-Tac. It serves as an official federal record relevant to noise and environmental policy affecting communities around the airport.

This 1990 Final Environmental Assessment, published by the U.S. Department of Transportation's Federal Aviation Administration, examines proposed changes to air traffic arrival and departure routes at Seattle-Tacoma International Airport. Volume II of the document compiles public comments received in response to the Draft Environmental Assessment, reflecting community input on how the proposed route changes could affect noise and other environmental conditions in the Seattle, Washington area.
