aircraft and properly contains IFR aircraft operating on direct routes 
under the control of Salt Lake City Air Route Traffic Control Center 
(ARTCC) and Seattle ARTCC.

DATES: Effective 0901 UTC, October 7, 2021. The Director of the Federal

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 establishes Class E airspace at Missoula, MT, to ensure the 
safety and management of IFR operations in the National Airspace 
System.

History

    The FAA published a notice of proposed rulemaking (NPRM) in the 
Federal Register (86 FR 20468; April 20, 2021) for Docket No. FAA-2021-
0207 to establish Class E airspace at Missoula, MT. Interested parties 
were invited to participate in this rulemaking effort by submitting 
written comments on the proposal to the FAA. One comment, in favor of 
the proposed action, was received.
    Subsequent to the publication of the NPRM, the FAA determined that 
the proposed Class E6 airspace for Missoula, MT included a minor 
overlap into the proposed Class E6 airspace for Great Falls, MT (86 FR 
18485; April 9, 2021). To remove the overlapping airspace, an 
additional geographic point has been added to the Missoula, MT Class E6 
airspace legal description. This change does not have a significant 
impact on the proposed airspace boundaries in the NPRM. The geographic 
point that has been added to the Final Rule's legal description is 
``lat 47[deg]41'18'' N, long 112[deg]36'32'' W.''
    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 designation listed in this document will be published 
subsequently in the Order.

Availability and Summary of Documents for Incorporation by Reference

    This document amends 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 Rule

    This amendment to 14 CFR part 71 establishes Class E en route 
domestic airspace extending upward from 1,200 feet above the surface at 
Missoula, MT. This action provides controlled airspace to facilitate 
vectoring of IFR aircraft under the control of Salt Lake City and 
Seattle ARTCCs. The airspace also ensures proper containment of IFR 
aircraft operating on direct routes where the current en route 
structure is insufficient.
    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 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

    The FAA has determined that this action qualifies for categorical 
exclusion under the National Environmental Policy Act in accordance 
with FAA Order 1050.1F, ``Environmental Impacts: Policies and 
Procedures,'' paragraph 5-6.5a. This airspace action is not expected to 
cause any potentially significant environmental impacts, and no 
extraordinary circumstances exist that warrant the preparation of an 
environmental assessment.
