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 the 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 modifies 

Class E airspace to supports the safety 

and management of IFR operations at 

Alliance Municipal Airport.

Federal Register / Vol. 88, No. 179 / Monday, September 18, 2023 / Rules and Regulations 63837 

History 

The FAA published a notice of 

proposed rulemaking for Docket No. 

FAA–2023–0583 in the Federal Register 

(88 FR 22385, April 13, 2023), 

proposing to modify Class E airspace at 

Alliance Municipal Airport, Alliance, 

NE. Interested parties were invited to 

participate in this rulemaking effort by 

submitting written comments on the 

proposal to the FAA. No comments 

were received. The FAA published a 

final rule for this docket in the Federal 

Register (88 FR 55553) on August 16, 

2023, with an effective date of October 

5, 2023. For administrative reasons, the 

FAA republishes this final rule with a 

delayed effective date of November 30, 

2023, and an amendment to the 

currently effective version of FAA Order 

JO 7400.11. 

Incorporation by Reference 

Class E5 airspace area is published in 

paragraph 6005 of FAA Order JO 

7400.11, Airspace Designations and 

Reporting Points, which is incorporated 

by reference in 14 CFR 71.1 on an 

annual basis. This document amends 

the current version of that order, FAA 

Order JO 7400.11H, dated August 11, 

2023 and effective September 15, 2023. 

FAA Order JO 7400.11H is publicly 

available as listed in the ADDRESSES

section of this document. These 

amendments will be published in the 

next update to FAA Order JO 7400.11. 

FAA Order JO 7400.11H lists Class A, 

B, C, D, and E airspace areas, air traffic 

service routes, and reporting points. 

The Rule 

This action amends 14 CFR part 71 by 

modifying Class E airspace beginning at 

700 feet above the surface at Alliance 

Municipal Airport, NE. Class E airspace 

beginning at 700 feet above the surface 

is expanded to a 7.6-mile radius to fully 

contain arriving IFR aircraft operating 

below 1,500 feet above the surface. 

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. 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 only affects air traffic 

procedures and air navigation, it is 

certified that this rule, when 

promulgated, does 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 5–6.5.a. 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.

DEPARTMENT OF TRANSPORTATION 

Federal Aviation Administration 

14 CFR Part 97 

[Docket No. 31505; Amdt. No. 4077] 

Standard Instrument Approach 

Procedures, and Takeoff Minimums 

and Obstacle Departure Procedures; 

Miscellaneous Amendments 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This rule establishes, amends, 

suspends, or removes Standard 

Instrument Approach Procedures 

(SIAPS) and associated Takeoff 

Minimums and Obstacle Departure 

procedures (ODPs) for operations at 

certain airports. These regulatory 

actions are needed because of the 

adoption of new or revised criteria, or 

because of changes occurring in the 

National Airspace System, such as the 

commissioning of new navigational 

facilities, adding new obstacles, or 

changing air traffic requirements. These 

changes are designed to provide safe 

and efficient use of the navigable 

airspace and to promote safe flight 

operations under instrument flight rules 

at the affected airports. 

DATES: This rule is effective September 

18, 2023. The compliance date for each 

SIAP, associated Takeoff Minimums, 

and ODP is specified in the amendatory 

provisions. 

The incorporation by reference of 

certain publications listed in the 

regulations is approved by the Director 

of the Federal Register as of September 

18, 2023.

amendment is as follows:
