Proposed Amendment of Class E Airspace; Dillon, MT

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (SNPRM).

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

SUMMARY: The FAA is issuing a SNPRM for the notice of proposed 
rulemaking (NPRM) published on March 15, 2012, in order to elicit 
comments addressing the proposed amendment to create Class E surface 
airspace and further expand the previous proposed amendment of Class E 
airspace extending upward from 700 feet above the surface at Dillon 
Airport, Dillon, MT, to accommodate aircraft using new Area Navigation 
(RNAV) Global Positioning System (GPS) standard instrument approach 
procedures. The original NPRM only proposed an amendment of Class E 
airspace extending upward from 700 feet above the surface.

DATES: Comments must be received on or before August 27, 2012.

ADDRESSES: Send comments on this proposal to the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor,

SUPPLEMENTARY INFORMATION: 

History

    On March 15, 2012, the FAA published a NPRM to modify Class E 
airspace, extending upward from 700 feet or more above the surface, at 
Dillon Airport, Dillon, MT (77 FR 15295). The comment period closed 
April 30, 2012. One comment was received.
    The commenter recommended establishing Class E surface airspace, 
and also expand the Class E airspace extending upward from 700 feet 
above the surface for aircraft safety. The FAA found merit in this 
comment, and, therefore, proposes the additional creation of Class E 
surface airspace, and modification of existing Class E airspace 
extending upward from 700 feet above the surface. The FAA seeks 
comments on this SNPRM.

Comments Invited

    Interested parties are invited to participate in this proposed 
rulemaking by submitting such written data, views, or arguments, as 
they may desire. Comments that provide the factual basis supporting the 
views and suggestions presented are particularly helpful in developing 
reasoned regulatory decisions on the proposal. Comments are 
specifically invited on the overall regulatory, aeronautical, economic, 
environmental, and energy-related aspects of the proposal.
    Communications should identify both docket numbers (FAA Docket No. 
FAA 2011-1213 and Airspace Docket No. 11-ANM-23) and be submitted in 
triplicate to the Docket Management System (see

[[Page 40835]]

postcard will be date/time stamped and returned to the commenter.
    All communications received on or before the specified closing date 
for comments will be considered before taking action on the proposed 
rule. The proposal contained in this action may be changed in light of 
comments received. All comments submitted will be available for

The Supplemental Proposal

    The FAA is proposing an amendment to Title 14 Code of Federal 
Regulations (14 CFR) part 71 by creating Class E surface airspace and 
modifying existing Class E airspace extending upward from 700 feet 
above the surface at Dillon Airport, Dillon MT, to accommodate aircraft 
using new RNAV (GPS) standard instrument approach procedures at Dillon 
Airport. This action would enhance the safety and management of IFR 
operations at the airport. The geographic coordinates of the airport 
also would be adjusted.
    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 that 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 that 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 propose controlled airspace at Dillon Airport, Dillon, MT.
    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.
