Establishment and Modification of 

Class E Airspace; Williston Basin, ND 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action establishes a Class 

E airspace area, designated as an 

extension to a Class D or Class E surface 

area, at Williston Basin International 

Airport, Williston, ND. This action also 

modifies the Class E airspace extending 

upward from 700 feet above the surface. 

The airspace modifications support the 

establishment of new instrument 

procedures for runways 04 and 22. This 

action also updates the geographic 

coordinates in the Class E2 and Class E5 

text headers. The airspace supports 

instrument flight rules (IFR) operations 

at the airport. 

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 and modifies Class E airspace at 

Williston Basin International Airport, 

Williston, ND, to ensure the safety and 

management of IFR operations at the 

airport. 

History 

The FAA published a notice of 

proposed rulemaking in the Federal 

Register (86 FR 21672; April 23, 2021) 

for Docket No. FAA–2021–0292 to 

modify the Class E airspace at Williston 

Basin International Airport, Williston, 

ND. 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 publication of the NPRM, 

the FAA determined that Class E4 

airspace should be established versus 

modifying the Class E2 airspace. This 

action corrects the NPRM by 

establishing Class E4 airspace. This 

airspace area is designed to contain IFR 

aircraft descending below 1,000 feet 

above the surface on the VOR RWY 22 

approach. The new Class E4 area is 

identical to the Class E2 modification 

that was proposed in the NPRM. The 

airspace is described as ‘‘That airspace 

extending upward from the surface 

within 2.4 miles each side of the 045° 

bearing from the airport, extending from 

the Class E2’s 4.2-mile radius to 6.8 

miles northeast of the airport.’’ 

Class E2, E4, and E5 airspace 

designations are published in 

paragraphs 6002, 6004, and 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 

establishes a Class E airspace area, 

designated as an extension to a Class D 

or Class E surface area, at Williston 

Basin International Airport, Williston, 

ND. This airspace area is established 

northeast of the airport and is designed 

to contain arriving IFR aircraft 

descending below 1,000 feet above the 

surface on the VOR RWY 22 approach. 

Additionally, this action modifies the 

Class E airspace extending upward from 

700 feet above the surface. This airspace 

is designed to contain arriving IFR 

aircraft descending below 1,500 feet 

above the surface and departing IFR 

aircraft until reaching 1,200 feet above 

the surface. An area northeast and 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 86, No. 133 / Thursday, July 15, 2021 / Rules and Regulations 37235 

another southwest of the airport are 

added to contain IFR aircraft arriving 

and departing the airport. 

Lastly, the action updates the 

geographic coordinates in the Class E2 

and Class E5 text headers. The 

coordinates are updated to ‘‘lat. 

48°15′35′′ N, long. 103°45′02′′ W,’’ to 

match the FAA database. 

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.

Extension of Canadian Area Navigation 

Routes Q–902 and Q–811; Alaska 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action amends Federal 

airways, A–15, V–444, J–502, and J–511 

in Alaska. It also establishes an 

extension of two Canadian Area

The modifications are necessary due to 

the decommissioning of the Burwash 

Non-Directional Beacon (NDB) in Yukon

navigation guidance for portions of the 

affected routes. The Burwash NDB was 

decommissioned effective March 26,
