## Abstract

This action amends the Class D airspace at Chicago/Rockford, IL, and the Class E airspace at Poplar Grove, IL; Freeport, IL; Rochelle, IL; and Chicago/Rockford, IL. This action is the result of airspace reviews caused by the decommissioning of the Rockford very high frequency (VHF) omnidirectional range (VOR) as part of the VOR Minimal Operational Network (MON) Program. The names and geographic coordinates of various airports are also being updated to coincide with the FAA's aeronautical database.
