Revision to the Legal Description of the Riverside, March Air Force Base (AFB), Class C Airspace Area; CA

This action revises the legal description of the Riverside March AFB, CA, Class C airspace area by replacing references to the former active duty AFB with the current civil/military joint-use designation of ``March Field.'' Additionally, this action changes the legal description to reflect the current operating hours for the Class C airspace area which are consistent with the current mission requirements of the U.S. Air Force (USAF) Reserve, the U.S. Customs Service, and other tenants operating at this airport. The Class C airspace area is designated effective during the specific days and times of operation of the March Ground Controlled Approach (GCA) facility as established in advance by a Notice to Airmen (NOTAM). The effective dates and times will thereafter be continuously published in the Airport/Facility Directory. This action will not change the actual dimensions, configuration, or operating requirements of the Riverside, March Field, CA, Class C airspace area.
