Hangar 101 Demolition – Emergency Action

The Duluth Airport Authority, in cooperation with the Federal Aviation Administration, announces the availability of the Environmental Assessment. The Duluth Airport Authority, under an emergency action, demolished the vacant and condemned Hangar 101 (the project) due to health and safety concerns. Previously, Hangar 101, a historic property, was condemned by the city of Duluth Office of Construction Services and Inspections Division and an EA was planned. However, severe weather and a recent wind storm caused extensive damage and it was determined structurally unsound, unsafe, and an inimical threat to community safety.

The EA provides information on the project and discusses the potential economic, social, environmental impacts, and mitigation measures, as appropriate, of the project. It has been prepared pursuant to the requirements of Section 102(2)(c) of the National Environmental Policy Act of 1969 (NEPA), and in accordance with FAA Order 1050.1F, Environmental Impacts: Policies and Procedures, FAA Order 5050.4B, NEPA Implementing Instructions for Airport Actions. The EA also addresses the adverse impact to the historic hangar in accordance with Section 106 of the National Historic Preservation Act (54 USC § 306108) and physical use of a Section 4(f) property in accordance with the U.S. Department of Transportation Act (49 USC § 303).
