SUPPLEMENTARY INFORMATION:

History

    On June 21, 2011, the FAA published in the Federal Register a 
notice of proposed rulemaking to amend controlled airspace at Casper, 
WY (76 FR 36017). Interested parties were invited to participate in 
this rulemaking effort by submitting written comments on the proposal 
to the FAA. No comments were received.
    Class D and Class E airspace designations are published in 
paragraphs 5000, 6002, 6004, 6005 and 6006, respectively, of FAA Order 
7400.9U dated August 18, 2010, and effective September 15, 2010, which 
is incorporated by reference in 14 CFR 71.1. The Class D and Class E 
airspace designations listed in this document will be published 
subsequently in that Order.

The Rule

    This action amends Title 14 Code of Federal Regulations (14 CFR) 
part 71 by amending Class D airspace, Class E surface airspace, Class E 
airspace designated as an extension, and Class E airspace extending 
upward from 700/1,200 feet above the surface, by adjusting the 
geographic coordinates of Casper, Natrona County International Airport 
to be in concert with the FAA's aeronautical database. Also, this 
action establishes Class E en route domestic airspace extending upward 
from 1,200 feet above the surface to facilitate vectoring of Instrument 
Flight Rules (IFR) traffic from en route airspace to the airport. This 
enhances the safety and management of IFR operations at the airport.
    The FAA has determined this regulation only involves an established 
body of technical regulations for which frequent and routine amendments 
are necessary to keep them operationally current. Therefore, this 
regulation: (1) Is not a ``significant regulatory action'' under 
Executive Order 12866; (2) is not a ``significant rule'' under DOT 
Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); 
and (3) does not warrant preparation of a regulatory evaluation as the 
anticipated impact is so minimal. Since this is a routine matter that 
will only affect air traffic procedures and air navigation, it is 
certified this rule, when promulgated, will not have a significant 
economic impact on a substantial number of small entities under the 
criteria of the Regulatory Flexibility Act. The FAA's authority to 
issue rules regarding aviation safety is found in Title 49 of the U.S. 
Code. Subtitle 1, section 106 discusses the authority of the FAA 
Administrator. Subtitle VII, Aviation Programs, describes in more 
detail the scope of the agency's authority. This rulemaking is 
promulgated under the authority described in subtitle VII, part A, 
subpart I, section 40103. Under that section, the FAA is charged with 
prescribing regulations to assign the use of airspace necessary to 
ensure the safety of aircraft and the efficient use of

airspace. This regulation is within the scope of that authority as it 
establishes additional controlled airspace at Casper, Natrona County 
International Airport, Casper, WY.
