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 modifies the Class E airspace at Missoula International Airport, 
Missoula, MT, to ensure the safety and management of instrument flight 
rules (IFR) operations at the airport.

History

    The FAA published a notice of proposed rulemaking in the Federal 
Register (86 FR 18488; April 9, 2021) for Docket No. FAA-2021-0208 to 
modify the Class E airspace at Missoula International Airport, 
Missoula, MT. Interested parties were invited to participate in this 
rulemaking effort by submitting written comments on the proposal to the 
FAA. One comment was received. The commenter suggested that the Class 
E5 airspace boundaries should be expanded to encompass all of the Class 
G airspace, extending upward from 1,200 feet above the surface, near 
the airport. The FAA does not agree. Title 49 of the US Code provides 
the FAA with its legal authority to manage the NAS. It also provides 
that citizens of the United States have a public right of transit 
through navigable airspace. Minimizing the volume of regulated airspace 
ensures the FAA is being consistent to its legislated responsibilities. 
Class E5 airspace is designed to contain IFR operations transitioning 
to or from the terminal and en route environments. Expanding the 
airspace boundaries for the sole purpose of reducing areas of Class G 
airspace would not be appropriate.
    Class E5 airspace designations are published in paragraph 6005 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 modifies the Class E airspace, 
extending upward from 1,200 feet above the surface, at Missoula 
International Airport, Missoula, MT. This airspace is designed to 
contain IFR aircraft transitioning to/from the terminal and en route 
environments. This action proposes to increase the airspace's radius of 
the airport from 35 miles to 46 miles. The 46-mile radius will properly 
contain IFR aircraft transitioning to/from the airport.
    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.
