Action
Final rule.
Summary
This action amends the Class D and Class E airspace at Sioux Gateway Airport/Brigadier General Bud Day Field, Sioux City, IA. This action is the result of an airspace review caused by the decommissioning of the Sioux City VHF omnidirectional range (VOR) navigation aid as part of the VOR Minimum Operational Network (MON) Program. The name and geographic coordinates of the airport are also being updated to coincide with the FAA's aeronautical database.
