Proposed Establishment of Class E Airspace; Missoula, MT

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: This action proposes to establish Class E domestic en route 
airspace extending upward from 1,200 feet above the surface at 
Missoula, MT. This airspace would facilitate vectoring of Instrument 
Flight Rules (IFR) aircraft and would properly contain IFR aircraft 
operating on direct routes under the control of Salt Lake City Air 
Route Traffic Control Center (ARTCC) and Seattle ARTCC. The FAA is 
proposing this action to enhance the safety and management of IFR 
operations within the National Airspace System (NAS).

DATES: Comments must be received on or before June 4, 2021.

ADDRESSES: Send comments on this proposal to the U.S. Department of 
Transportation, Docket Operations, 1200 New Jersey Avenue SE, West

SUPPLEMENTARY INFORMATION:

Authority for This Rulemaking

    The FAA's authority to issue rules regarding aviation safety is 
found in Title 49 of the United States Code. Subtitle I, Section 106 
describes 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 would establish Class E airspace at Missoula, MT, to support IFR 
operations within the NAS.

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 and be submitted in 
triplicate to the address listed above. Persons wishing the FAA to 
acknowledge receipt of their comments on this notice must submit with 
those comments a self-addressed, stamped postcard on which the 
following statement is made: ``Comments to Docket No. FAA-2021-0207; 
Airspace Docket No. 21-ANM-6''. The postcard will be date/time stamped 
and returned to the commenter.
    All communications received before the specified closing date for 
comments will be considered before taking action on the proposed rule. 
The proposal contained in this notice may be changed in light of the 
comments received. A report summarizing each substantive public contact 
with FAA personnel concerned with this rulemaking will be filed in the 
docket.

Availability and Summary of Documents for Incorporation by Reference

    This document proposes to amend FAA Order 7400.11E, Airspace 
Designations and Reporting Points, dated July 21, 2020, and effective 
September 15, 2020. FAA Order 7400.11E is publicly available as listed 
in the ADDRESSES section of this document. FAA Order 7400.11E lists 
Class A, B, C, D, and E airspace areas, air traffic service routes, and 
reporting points.

The Proposal

    The FAA is proposing an amendment to 14 CFR part 71 by establishing 
Class E en route domestic airspace extending upward from 1,200 feet 
above the surface at Missoula, MT. This action would provide controlled 
airspace to facilitate vectoring of IFR aircraft under the control of 
Salt Lake City and Seattle ARTCCs. The airspace would also ensure 
proper containment of IFR aircraft operating on direct routes where the 
current en route structure is insufficient. This action would enhance 
the safety and management of IFR operations within the NAS.
    Class E6 airspace designations are published in paragraph 6006 of 
FAA Order 7400.11E, dated July 21, 2020, and effective September 15, 
2020, which is incorporated by reference in 14 CFR 71.1. The Class E 
airspace designations listed in this document will be published 
subsequently in the Order.
    FAA Order 7400.11, Airspace Designations and Reporting Points, is 
published yearly and effective on September 15.

Regulatory Notices and Analyses

    The FAA has determined that this regulation only involves an 
established body of technical regulations for which frequent and 
routine amendments are

[[Page 20469]]

necessary to keep them operationally current, is non-controversial, and 
unlikely to result in adverse or negative comments. It, therefore: (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 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.

Environmental Review

    This proposal will be subject to an environmental analysis in 
accordance with FAA Order 1050.1F, ``Environmental Impacts: Policies 
and Procedures'' prior to any FAA final regulatory action.
