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 would 

amend the airway structure as necessary 

to preserve the safe and efficient flow of 

air traffic within the National Airspace 

System. 

Comments Invited 

The FAA invites interested persons to 

participate in this rulemaking by 

submitting written comments, data, or 

views. Comments are specifically 

invited on the overall regulatory, 

aeronautical, economic, environmental, 

and energy-related aspects of the 

proposal. The most helpful comments 

reference a specific portion of the 

proposal, explain the reason for any 

recommended change, and include 

supporting data. To ensure the docket 

does not contain duplicate comments, 

commenters should submit only one 

time if comments are filed 

electronically, or commenters should 

send only one copy of written 

comments if comments are filed in 

writing. 

The FAA will file in the docket all 

comments it receives, as well as a report 

summarizing each substantive public 

contact with FAA personnel concerning 

this proposed rulemaking. Before acting 

on this proposal, the FAA will consider 

all comments it receives on or before the 

closing date for comments. The FAA 

will consider comments filed after the 

comment period has closed if it is 

possible to do so without incurring 

expense or delay. The FAA may change 

this proposal in light of the comments 

it receives. 

Privacy: In accordance with 5 U.S.C. 

553(c), DOT solicits comments from the 

public to better inform its rulemaking 

process. DOT posts these comments, 

without edit, including any personal 

information the commenter provides, to 

www.regulations.gov, as described in 

the system of records notice (DOT/ALL– 

14 FDMS), which can be reviewed at 

www.dot.gov/privacy.

An electronic copy of this document 

may be downloaded through the 

internet at www.regulations.gov. 

Recently published rulemaking 

documents can also be accessed through 

the FAA’s web page at www.faa.gov/air_

operations). An informal docket may 

also be examined during normal 

business hours at the office of the 

Western Service Center, Federal 

Aviation Administration, 2200 South 

216th St., Des Moines, WA 98198. 

Incorporation by Reference 

Colored Federal Airways are 

published in paragraph 6009 and 

Alaskan VOR Federal Airways are 

published in paragraph 6010 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 proposes to amend the 

current version of that order, FAA Order 

JO 7400.11J, dated July 31, 2024, and 

effective September 15, 2024. These 

updates would be published in the next 

update to FAA Order JO 7400.11. That 

order is publicly available as listed in 

the ADDRESSES section of this document. 

FAA Order JO 7400.11J lists Class A, 

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

service routes, and reporting points. 

Background 

In 2003, Congress enacted the Vision 

100-Century of Aviation 

Reauthorization Act (Pub. L. 108–176), 

which established a joint planning and 

development office in the FAA to 

manage the work related to the Next 

Generation Air Transportation System 

(NextGen). Today, NextGen is an 

ongoing FAA-led modernization of the 

nation’s air transportation system to 

make flying safer, more efficient, and 

more predictable. 

In support of NextGen, this proposal 

is part of an ongoing, large, and 

comprehensive airway modernization 

project in the state of Alaska. Part of this 

project is to transition the Alaskan en 

route navigation structure away from 

dependency on NDBs and move to 

develop and improve the Area 

Navigation (RNAV) route structure. The 

FAA is planning to decommission the 

St. Marys and Aniak NDBs in the state 

of Alaska. As a result, Colored Federal 

Airway G–6 and Alaskan Federal 

Airways V–459 and V–496 will become 

unusable. The mitigation to the loss of 

G–6 is RNAV Route T–380 which 

overlays the entire routing of G–6. The 

mitigation to the loss of V–459 is RNAV 

Route T–380 which is near V–459. The 

mitigation to the loss of V–496 is RNAV 

Route T–382 which overlays the entire 

routing of V–496. 

The Proposal 

The FAA is proposing an amendment 

to 14 CFR part 71 to revoke Colored 

Federal Airway Green (G–6) and 

Alaskan VOR Federal Airways V–459 

and V–496 in Alaska. The FAA is 

proposing these actions due to the 

pending decommissioning of the St. 

Marys, AK, NDB and the Aniak, AK, 

NDB. 

G–6: G–6 currently extends between 

the St. Marys, AK, NDB and the Aniak, 

AK, NDB. Due to the pending 

decommissioning of both NDBs, the 

FAA is proposing to revoke G–6 in its 

entirety. 

V–459: V–459 in Alaska currently 

extends between the Emmonak, AK, 

VOR/Distance Measuring Equipment 

(DME) and the St. Marys, AK, NDB. Due 

to the pending decommissioning of the 

St. Marys NDB, the FAA is proposing to 

revoke the Alaskan V–459 in its 


lotter on DSK11XQN23PROD with PROPOSALS1
8512 Federal Register / Vol. 90, No. 19 / Thursday, January 30, 2025 / Proposed Rules 

entirety. This action does not propose 

any changes to the V–459 in California. 

V–496: V–496 currently extends 

between the Hooper Bay, AK, VOR/DME 

and the St. Marys, AK, NDB. Due to the 

pending decommissioning of the St. 

Marys NDB, the FAA is proposing to 

revoke V–496 in its entirety. 

Regulatory Notices and Analyses 

The FAA has determined that this 

proposed 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 will 

only affect air traffic procedures and air 

navigation, it is certified that this 

proposed rule, when promulgated, will 

not have a significant economic impact 

on a substantial number of small entities 

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.
