Amendment of Class B Airspace Description; St. Louis, MO

This action amends the description of the St. Louis, MO, Class B airspace area by changing the references for defining the center point of the airspace from the Cardinal VHF Omnidirectional Range/ Distance Measuring Equipment (VOR/DME) to "Point of Origin" due to the planned decommissioning of the Cardinal, MO, VOR/DME. The St. Louis Class B airspace description is edited further to update the St. Louis Lambert International Airport name, St. Charles County Smartt Airport name, and airport reference point (ARP) geographic coordinates for the airports to match the current information in the FAA's aeronautical database. The Creve Coeur Airport ARP and St. Louis Lambert International Airport Instrument Landing System (ILS) Runway 30L Localizer geographic coordinates are also updated to match the FAA's aeronautical database. In addition, the airspace description is edited throughout to improve accuracy and clarity. These changes are editorial only and do not alter the current charted boundaries, altitudes, or ATC procedures for the St. Louis, MO, Class B airspace area.
