Amendment of Class E Airspace; Dillon, MT

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: This action amends Class E airspace, designated as a surface 
area, at Dillon Airport, Dillon, MT. This action reduces the radius of 
the airspace and adds an extension to the northeast of the airport. 
This action also amends the Class E airspace extending upward from 700 
feet above the surface, the action reduces the circular radius around 
the airport and adds an extension to the southwest of the airport and 
an extension to the north of the airport. Additionally, this action 
amends the Class E airspace extending upward from 1,200 feet above the 
surface. The action significantly reduces the dimensions of the area to 
properly size it to contain IFR aircraft transitioning to/from the 
terminal or en route environments. Lastly, this action implements an 
administrative correction to the Class E airspace designated as a 
surface area.

DATES: Effective 0901 UTC, September 10, 2020. The Director of the 
Federal Register approves this incorporation by reference action under 
Title 1 Code of Federal Regulations part 51, subject to the annual 
revision of FAA Order 7400.11 and publication of conforming amendments.

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 amends Class E airspace at Dillon Airport, Dillon, 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 (85 FR 13080; March 6, 2020) for Docket No. FAA-2019-0874 to 
amend Class E airspace at Dillon Airport, Dillon, MT. Interested 
parties were invited to participate in this rulemaking effort by 
submitting written comments on the proposal to the FAA. No comments 
were received.
    After the NPRM comment period closed, the FAA identified an error 
in the proposed Class E airspace extending upward from 1,200 feet above 
the surface. The proposal stated the area should be reduced from a 45-
mile radius

[[Page 31671]]

to an 8-mile radius of the airport. However, to properly contain IFR 
aircraft transitioning to/from the terminal or en route environment, 
this area should be reduced to a 25-mile radius of the airport. The 
Final Rule includes a correction to the airspace area.
    Class E2 and E5 airspace designations are published in paragraphs 
6002 and 6005, respectively, of FAA Order 7400.11D, dated August 8, 
2019, 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 amends the Class E airspace, designated as a surface area, at 
Dillon Airport, Dillon, MT. The action reduces the area from a 6.1-mile 
radius to a 5.2-mile radius of the airport and adds an extension 
northeast of the airport. This area is described as follows: That 
airspace extending upward from the surface within a 5.2-mile radius of 
the airport, and with 2.4 miles each side of the 026[deg] bearing from 
the airport, extending from the 5.2-mile radius to 6.8 miles northeast 
of Dillon Airport.
    Also, this action amends Class E airspace extending upward from 700 
feet above the surface. This area is reconfigured a 9.2-mile radius of 
the airport to a 5.2-mile radius of the airport, with extensions 
southwest and north of the airport. This area is described as follows: 
That airspace extending upward from 700 feet above the surface within a 
5.2-mile radius of the airport, and within 3 miles each side of the 
205[deg] bearing from the airport, extending from the 5.2-mile radius 
to 9.9 miles southwest of the airport, and within eight miles west and 
four miles east of the 005[deg] bearing from the airport, extending 
from the 5.2-mile radius to 16 miles north of Dillon Airport.
    Additionally, this action amends the Class E airspace extending 
upward from 1,200 feet above the surface from a 45-mile radius to a 25-
mile radius of the airport.
    Lastly, this action implements an administrative correction to the 
Class E airspace designated as a surface area. This area is full time 
and the following two sentences do not accurately represent the time of 
use and are removed: ``This Class E airspace area is effective during 
specific dates and times established in advance by a Notice to Airmen. 
The effective date and time will thereafter be continuously published 
in the Airport/Facility Directory.''
    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.
