Welcome to the Northern California (NorCal) Optimization of Airspace and Procedures in the Metroplex (NorCal OAPM) Environmental Assessment Website

The FAA has prepared an Environmental Assessment (EA) in accordance with FAA Order 1050.1E. The FAA issued a Finding of No Significant Impact and Record of Decision (FONSI-ROD) for the project on August 7, 2014.

The EA and FONSI-ROD as well as other related documents can be accessed using the links to the left.

The Project

The NorCal OAPM proposed action would improve the efficiency of the National Airspace System in the Northern California Metroplex by optimizing aircraft arrival and departure routes at San Francisco International Airport (SFO), Oakland International Airport (OAK), Mineta San Jose International Airport (SJC) and Sacramento International Airport (SMF).  The project involves changes in aircraft flight routes and altitudes in certain areas.  Specifically, the FAA proposes to publish and implement optimized standard arrival and departure instrument procedures, serving air traffic flows into and out of airports in the Northern California Metroplex.  The proposed action does not require any ground disturbance or increase the number of aircraft operations within the Northern California Metroplex airspace area.
