Amendment of Class E Airspace; Rock Springs, WY

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This action amends Class E airspace at Rock Springs-Sweetwater 
County Airport, Rock Springs, WY. Decommissioning of the Rock Springs 
Tactical Air Navigation System (TACAN) has made this action necessary 
for the safety and management of Instrument Flight Rules (IFR) 
operations at the airport. This action also adjusts the geographic 
coordinates of the airport.

DATES: Effective date, 0901 UTC, July 26, 2012. The Director of the 
Federal Register approves this incorporation by reference action under 
1 CFR Part 51, subject to the annual revision of FAA Order 7400.9 and 
publication of conforming amendments.

SUPPLEMENTARY INFORMATION:

History

    On February 28, 2012, the FAA published in the Federal Register a 
notice of proposed rulemaking to amend controlled airspace at Rock 
Springs, WY (77 FR 11796). 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 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 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 E surface airspace, and Class E airspace 
extending upward from 700 feet above the surface, at Rock Springs-
Sweetwater County Airport. Airspace reconfiguration is necessary due to 
the decommissioning of the Rock Springs TACAN. Also, the geographic 
coordinates of the airport are updated to coincide with the FAA's 
aeronautical database. This action is necessary for 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 amends 
controlled airspace at Rock Springs-Sweetwater County Airport, Rock 
Springs, WY.

Environmental Review

    The FAA has determined that this action qualifies for categorical 
exclusion under the National Environmental Policy Act in accordance 
with FAA Order 1050.1E, ``Environmental Impacts: Policies and 
Procedures,'' paragraph 311a. This airspace action is not expected to 
cause any potentially significant environmental impacts, and no 
extraordinary circumstances exist that warrant preparation of an 
environmental assessment.
