# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Final rule.

# SUMMARY:

This action establishes Class E domestic en route airspace extending upward from 1,200 feet above the surface at Missoula, MT. This airspace facilitates vectoring of instrument flight rules (IFR) 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 Register approves this incorporation by reference action under 1 CFR 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 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°41′18″ N, long 112°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.
