Revision of Class E Airspace, Greeley, CO

This action revises the Class E airspace at Greeley, CO. A newly revised Airport Reference Point (ARP) coordinates at the Greeley- Weld Airport has made this action necessary. The change of the ARP coordinates required the legal description of Greeley-Weld Airport Class E airspace to reflect the new coordinates. Additionally, a revision to the Class E 700-feet controlled airspace, above the surface of the earth was required to reflect changes in airspace configurations in Colorado. The intended effect of this proposal is to provide adequate controlled airspace for Instrument Flight Rules (IFR) operations at Greeley-Weld Airport, Greeley, CO.
