This action will remove Class E airspace at St. George, UT, as the airport will be closing, eliminating the need for controlled airspace. This action will establish Class E airspace for the new St. George Municipal Airport located to the south of the original airport. Controlled airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS), VHF Omni- Directional Radio Range/Distance Measuring Equipment (VOR/DME), Localizer Type Directional Aid/Distance Measuring Equipment (LDA/DME) Standard Instrument Approach Procedures (SIAPs) at the new airport. This will improve the safety and management of Instrument Flight Rules (IFR) operations at the airport.
