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 amend Class D and 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 (84 FR 54792; October 11, 2019) for Docket No. FAA-2019-0761 
to amend 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. The 
FAA received one non-substantive comment discussing the potential 
impact on property values in the area. Though the comment isn't 
substantive, this action reduces the lateral boundaries for most of the 
Class E airspace established for the Missoula International Airport. 
The radius of the Class E airspace designated as a surface area will 
not change. The lateral boundaries of one area to the southeast of the 
airport will increase slightly.
    Subsequent to the publication of the NPRM, the FAA determined that 
a minor modification to one Class E airspace area, designated as an 
extension to a Class D or Class E surface area, would be beneficial. 
The NPRM defined this area as; within 0.7 miles each side of the 
142[deg] bearing extending from the 4.4-mile radius to 5.6 miles 
southeast of the airport. The NPRM definition created a small space or 
gap between this area and a nearby area of similar airspace. 
Additionally, the minimum distance authorized for the width of 
controlled airspace along a bearing is 1.0 mile. To remove this gap, 
enhance aeronautical charting and meet the minimum requirement for 
airspace widths, the area will be defined as; within 1.0 miles 
northeast and 1.2 miles southwest of the 142[deg] bearing from the 
airport, extending from the 4.4-mile radius to 5.6 miles southeast of 
the airport.

[[Page 12433]]

    Class D, Class E2, Class E4, and Class E5 airspace designations are 
published in paragraphs 5000, 6002, 6004 and 6005, respectively, of FAA 
Order 7400.11D, dated August 8, 2018, and effective September 15, 2019, 
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 7400.11D, Airspace Designations and 
Reporting Points, dated August 8, 2019, and effective September 15, 
2019. FAA Order 7400.11D is publicly available as listed in the 
ADDRESSES section of this document. FAA Order 7400.11D lists Class A, 
B, C, D, and E airspace areas, air traffic service routes, and 
reporting points.

The Rule

    This amendment to Title 14 Code of Federal Regulations (14 CFR) 
part 71 modifies Class E airspace designated as an extension to Class D 
or Class E surface areas at Missoula International Airport as follows: 
That airspace extending upward from the surface within 1.2 miles each 
side of the 310[deg] bearing from the airport, extending from the 4.4-
mile radius to 10.8 miles northwest of the airport, and within 1.3 
miles each side of the 295[deg] bearing from the airport, extending 
from the 4.4-mile radius to 5.6 miles northwest of the airport, and 
within 1.0 mile northeast and 1.2 miles southwest of the 142[deg] 
bearing from the airport, extending from the 4.4-mile radius to 5.6 
miles southeast of the airport, and within 1.5 miles each side of the 
171[deg] bearing from the airport, extending from the 4.4-mile radius 
to 10.6 miles south of the Missoula International Airport.
    This action also modifies Class E airspace extending upward from 
700 feet above the surface as follows: That airspace extending upward 
from the surface within 3.5 miles each side of the 311[deg] bearing 
from the airport, extending from the 4.4-mile radius to 22.3 miles 
northwest of the airport, and within 1.6 miles west and 4.3 miles east 
of the 179[deg] bearing from the airport, extending from the 4.4-mile 
radius to 15.2 miles south of the Missoula International Airport.
    Additionally, this action amends Class E airspace extending upward 
from 1,200 feet above the surface as follows: That airspace extending 
upward from 1,200 feet above the surface within a 35-mile radius of the 
Missoula International Airport.
    Further, this action removes the Missoula VORTAC from the legal 
description.
    Lastly, this action applies an administrative update to the Class D 
and Class E2 legal descriptions, replacing the term ``Airport/Facility 
Directory'' with ``Chart Supplement.''
    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 preparation of an 
environmental assessment.
