The Proposal

    The FAA is proposing an amendment to Title 14 Code of Federal 
Regulations (14 CFR) Part 71 by amending Class E surface airspace and 
Class E airspace extending upward from 700 feet above the surface at 
Rock Springs-Sweetwater County Airport, Rock Springs, WY. Airspace 
reconfiguration is necessary due to the decommissioning of the Rock 
Springs TACAN. Also, the geographic coordinates of the airport would be 
updated to coincide with the FAA's aeronautical database. This action 
would enhance the safety and management of IFR operations at Rock 
Springs-Sweetwater County Airport, Rock Springs, WY.
    Class E airspace designations are published in paragraph 6002 and 
6005, respectively, of FAA Order 7400.9V, dated August 9, 2011, and 
effective September 15, 2011, which is incorporated by reference in 14 
CFR 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 would modify controlled airspace at Rock Springs-Sweetwater 
County Airport, Rock Springs, WY.
    This proposal will be subject to an environmental analysis in 
accordance with FAA Order 1050.1E. ``Environmental Impacts: Policies 
and Procedures'' prior to any FAA final regulatory action.
