# 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                           ( print page 3892)                        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 the Class E airspace at Great Falls International Airport, Great Falls, MT, to support IFR operations at the airport.                

## Comments Invited

Interested parties are invited to participate in this proposed rulemaking by submitting such written data, views, or arguments, as they may desire. Comments that provide the factual basis supporting the views and suggestions presented are particularly helpful in developing reasoned regulatory decisions on the proposal. Comments are specifically invited on the overall regulatory, aeronautical, economic, environmental, and energy-related aspects of the proposal. Communications should identify both docket numbers and be submitted in triplicate to the address listed above. Persons wishing the FAA to acknowledge receipt of their comments on this notice must submit with those comments a self-addressed, stamped postcard on which the following statement is made: “Comments to Docket No. FAA-2020-1126; Airspace Docket No. 19-ANM-10”. The postcard will be date/time stamped and returned to the commenter.

All communications received before the specified closing date for comments will be considered before taking action on the proposed rule. The proposal contained in this notice may be changed in light of the comments received. A report summarizing each substantive public contact with FAA personnel concerned with this rulemaking will be filed in the docket.

## Availability and Summary of Documents for Incorporation by Reference

                    This document proposes to amend 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 Proposal

The FAA is proposing an amendment to Title 14 Code of Federal Regulations Part 71 by modifying the Class E airspace, designated as an extension to a Class D or Class E surface area, at Great Falls International Airport. This action proposes to reduce the size of the area to properly contain IFR aircraft descending below 1,000 feet above the surface. This area would be described as follows: That airspace extending upward from the surface within 1 mile each side of the 224° bearing from the airport, extending from the 5.5-mile radius to 9.6 miles southwest of Great Falls International Airport.

This action also proposes to modify the Class E airspace extending upward from 700 feet above the surface. This action proposes to significantly reduce the size of this area to properly contain IFR departures to 1,200 feet above the surface and IFR arrivals descending below 1,500 feet above the surface. This area would be described as follows: That airspace extending upward from 700 feet above the surface within a 7-mile radius of the airport, and within 3.4 miles each side of the 047° bearing from the airport, extending from the 7-mile radius to 12 miles northeast of the airport, and within 8 miles south and 4 miles north of the 222° from the airport, extending from 2.6 miles southwest of the airport to 18.7 miles southwest of Great Falls International Airport.

Additionally, this action proposes to modify the Class E airspace extending upward from 1,200 feet above the surface. This action would also reduce the size of this area to properly contain IFR aircraft transitioning to/from the terminal and en route environments. This area would be described as follows: That airspace extending upward from 1,200 feet above the surface within a 48-mile radius of Great Falls International Airport.

This action also proposes to remove the Great Falls VORTAC from the Class E4 and Class E5 text headers and airspace descriptions. The Navigational Aid (NAVAID) is not needed to describe the airspace areas. Removal of the NAVAID allows the airspace to be described from a single point, which simplifies the airspaces' descriptions.

Further, this action proposes to remove Malmstrom AFB from the Class E5 text header and airspace description. Reference to Malmstrom AFB is not needed to describe the airspace area. Removal of Malmstrom AFB allows the airspace to be described from a single point, which simplifies the airspace's description.

Lastly, this action proposes several administrative amendments to the airspaces' legal descriptions. The first line of the Class D and Class E4 text headers is not correct. The first line of text should not include the airport name, “International Airport” should be removed from this line of text. The airport's geographic coordinates in the Class D, Class E4, and Class E5 text header are incorrect. To match the FAA database, the geographic coordinates should be updated to lat. 47°28′56″ N, long. 111°22′13″ W.

Class D, E4, and E5 airspace designations are published in paragraphs 5000, 6004, and 6005, respectively, 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 D and Class E airspace designations listed in this document will be published subsequently in the Order.

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                           ( print page 3893)                        under the criteria of the Regulatory Flexibility Act.                

## Environmental Review

This proposal will be subject to an environmental analysis in accordance with FAA Order 1050.1F, “Environmental Impacts: Policies and Procedures” prior to any FAA final regulatory action.
