    Barnes v. Federal Aviation Administration – Ninth Circuit Court Opinion

    A federal appeals court denied a challenge by Oregon residents and an aviation watchdog group against a new runway project at Hillsboro Airport near Portland, Oregon. The court found that the Federal Aviation Administration acted properly in concluding the project would have no significant environmental impact, including only a minimal effect on air traffic and air quality. This case, a follow-up to a 2011 ruling, may be relevant to discussions of how environmental reviews are conducted for airport expansion projects in the Pacific Northwest.

    Finding of No Significant Impact (FONSI) and Record of Decision (ROD) for the Implementation of RNAV/RNP Procedures at Seattle-Tacoma International Airport (Greener Skies over Seattle)

    In November 2012, the Federal Aviation Administration (FAA) issued a Finding of No Significant Impact (FONSI) and Record of Decision (ROD) approving new satellite-based navigation procedures at Seattle-Tacoma International Airport (Sea-Tac) under the 'Greener Skies over Seattle' initiative. The new procedures, developed with Alaska Airlines, Boeing, and the Port of Seattle, use advanced RNAV/RNP technology to guide arriving aircraft along more precise, optimized descent paths, reducing fuel burn and environmental impact. The FAA determined that these airspace changes would not result in significant environmental harm or any physical airport development.
