It supplements Order 1050.1E, Environmental Impacts: Policies and Procedures, and provides information to FAA Airports personnel and others interested in fulfilling NEPA requirements for airport actions under FAA's authority. This order is part of FAA's effort to ensure its personnel have clear instructions to address potential environmental effects resulting from major airport actions.
