The Proposal

    The FAA is proposing an amendment to Title 14 Code of Federal 
Regulations (14 CFR) part 71 by amending the Class D and Class E 
airspace areas by adjusting the geographic coordinates of Casper, 
Natrona County International Airport to be in concert with the FAA's 
aeronautical database. Also, this action would establish Class E en 
route domestic airspace extending upward from 1,200 feet above the 
surface at the airport that would enhance the safety and management of 
IFR operations by vectoring IFR aircraft from en route airspace to the 
airport.
    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 part 71.1. The Class E airspace 
designation listed in this document will be published subsequently in 
this Order.
    The FAA has determined this proposed regulation only involves an 
established body of technical regulations for which frequent and 
routine amendments are necessary to keep them operationally current. 
Therefore, this proposed 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 proposed rule, when 
promulgated, would 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, describes 
the authority for 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 the 
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 creates additional controlled airspace at Casper, Natrona County 
International Airport, Casper, WY.
