## Abstract

This action modifies Class E airspace extending upward from 700 feet above the surface at Butler County Regional Airport-Hogan Field, Hamilton, OH. This action is due to an airspace review caused by the decommissioning of the Richmond VHF omnidirectional range (VOR), which provided navigation information to the instrument procedures at this airport, as part of the VOR Minimum Operational Network (MON) Program. Airspace redesign is necessary for the safety and management of instrument flight rules (IFR) operations at this airport.
