Since the summer of 2018, the Port of Seattle (Port) has been assisting the Federal Aviation Administration (FAA) with preparation of an environmental review for the proposed Sustainable Airport Master Plan Near-Term Projects (SAMP NTP) for Seattle-Tacoma International Airport (SEA). The first stage of the environmental review was scoping which was completed in 2019.
The next stage of the environmental review process is the draft National Environmental Policy Act (NEPA) Environmental Assessment (EA). The Port and the Federal Aviation Administration (FAA) have determined that additional time is needed to complete the analysis needed to meet NEPA requirements before the SAMP NTP EA is published. The Port and FAA are working together to update the schedule for the SAMP NTP EA and will provide information regarding the release of the draft NEPA EA once it is available.
Upon completion of the NEPA environmental review, the State Environmental Policy Act (SEPA) environmental review will follow. After SEPA is complete, Commission authorization will be required to initiate construction work on the projects.
