14 CFR Part 71

[Docket No. FAA-2012-0509; Airspace Docket No. 12-ANM-15]

Proposed Amendment of Class E Airspace; Casper, WY

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: This action proposes to modify the Class E airspace areas at 
Casper, Natrona County International Airport, Casper, WY, to facilitate 
vectoring of Instrument Flight Rules (IFR) traffic from en route 
airspace to the airport. Decommissioning of the Muddy Mountain VOR 
Omnidirectional Range Tactical Air Navigation (VORTAC) has made 
reconfiguration necessary for the safety and management of aircraft 
operations at Casper, Natrona County International Airport, Casper, WY.

DATES: Comments must be received on or before December 31, 2012.

ADDRESSES: Send comments on this proposal to the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 20590; 
telephone (202) 366-9826. You must identify FAA Docket No. FAA-2012-
0509; Airspace Docket No. 12-ANM-15, at the beginning of your comments. 
You may also submit comments through the Internet at http://www.regulations.gov.

The Proposal

    The FAA is proposing an amendment to Title 14 Code of Federal 
Regulations (14 CFR) part 71 by modifying Class E airspace designated 
as an extension to a Class D surface area, and Class E airspace 
extending upward from 700 feet above the surface due to the 
decommissioning of the Muddy Mountain VORTAC at Casper, Natrona County 
International Airport, Casper, WY. This action also would amend Class E 
en route domestic airspace extending upward from 1,200 feet above the 
surface at the airport by removing the exclusionary language in the 
regulatory text. This action would enhance the safety and management of 
aircraft operations at the airport.
    Class E airspace designations are published in paragraphs, 6004, 
6005 and 6006, respectively, of FAA Order 7400.9W, dated August 8, 
2012, and effective September 15, 2012, 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

[[Page 67783]]

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 Casper, Natrona County 
International Airport, Casper, 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.
