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 

expand the availability of RNAV routing 

in Alaska and improve the efficient flow 

of air traffic within the National 

Airspace System (NAS) by lessening the 

dependency on ground based 

navigation.

Availability and Summary of 

Documents for Incorporation by 

Reference 

This document proposes to amend 

FAA Order JO 7400.11F, Airspace 

Designations and Reporting Points, 

dated August 10, 2021, and effective 

September 15, 2021. The Order is 

publicly available as listed in the 

ADDRESSES section of this document. 

The Order 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 a larger and comprehensive Troute modernization project in the state 

of Alaska. The project mission statement 

states: ‘‘To modernize Alaska’s Air 

Traffic Service route structure using 

satellite based navigation Development 

of new T-routes and optimization of 

existing T-routes will enhance safety, 

increase efficiency and access, and will 

provide enroute continuity that is not 

subject to the restrictions associated 

with ground based airway navigation.’’ 

As part of this project, the FAA 

evaluated the existing Colored Airway 

structure for: (a) Direct replacement (i.e., 

overlay) with a T-route that offers a 

similar or lower Minimum Enroute 

Altitude (MEA) or Global Navigation 

Satellite System Minimum Enroute 

Altitude (GNSS MEA); (b) the 

replacement of the colored airway with 

a T-route in an optimized but similar 

geographic area, while retaining similar 

or lower MEA; or (c) removal with no 

route structure (T-route) restored in that 

area because the value was determined 

to be insignificant. 

The aviation industry/users have 

indicated a desire for the FAA to 

transition the Alaskan enroute 

navigation structure away from 

dependency on Non-Directional 

Beacons (NDB), and move to develop 

and improve the RNAV route structure. 

Given these facts, the FAA proposes to 

amend two segments of RNAV route T– 

222. The amendments would reroute the 

segment between the Bethel (BET), AK, 

VHF omnidirectional range beacon and 

tactical air navigation system (VORTAC) 

to the UTICE, AK, waypoint (WP), and 

cancel the segment between the BAERE, 

AK, WP and the Saint Paul Island (SPY), 

AK, NDB. The proposed amendment of 

these segments would provide for lower 

MEAs while also ensuring that the 

appropriate route criteria is met along 

the entire route. 

The Proposal 

The FAA is proposing an amendment 

to 14 CFR part 71 to amend RNAV route 

T–222 in the vicinity of Bethel, AK in 

support of a large and comprehensive Troute modernization project for the state 

of Alaska. The proposed route changes 

are described below. 

T–222: T–222 currently extends from 

the BAERE, AK, WP to the Fairbanks 

(FAI), AK, VORTAC. The FAA proposes 

to reroute the segment between BET and 

the UTICE, AK, WP by adding five 

additional WPs (CABOT, WOGAX, 

IKUFU, JILSI, and CYCAS) in the 

vicinity of Aniak, AK. The additional 

WPs will allow for a lower GNSS MEA 

that would more closely match the 

current colored airway, R–39, and 

would serve as an acceptable 

alternative. The RUFVY WP, which was 

in the original legal description, would 

be removed due to it not being a turn 

point. Additionally, the FAA proposes 

to cancel the segment between BAERE 

WP and SPY, due to changes in route 

criteria that would require a raising of 

the GNSS MEA due to terrain near 

BAERE WP and limitation of two-way 

VHF communications for the over-water 

portion to SPY. Loss of this segment 

would be mitigated by utilizing VOR 

Federal airway V–480 that parallels the 

existing route. The rest of the route 

would remain unchanged. 

United States Area Navigation Routes 

are published in paragraph 6011 of FAA 

Order JO 7400.11F dated August 10, 

2021 and effective September 15, 2021, 

which is incorporated by reference in 14 

CFR 71.1. The RNAV route listed in this 

document would be published 

subsequently in the Order. 

FAA Order JO 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 

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 Department of 

Transportation (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.

I. Summary of EPA’s Proposed Action 

In accordance with the Clean Air Act 

(CAA or Act), EPA is proposing to 

approve the Montgomery County Area 

LMP for the 1997 8-hour ozone NAAQS, 

adopted by TDEC on June 10, 2020, and 

submitted by TDEC as a revision to the 

Tennessee SIP on June 23, 2020. In 

2004, the Montgomery County Area was 

designated as nonattainment for the 

1997 8-hour ozone NAAQS. 

Subsequently, in 2005, after having 

clean data and EPA’s approval of a 

maintenance plan, the Area was 

redesignated to attainment for the 1997 

8-hour ozone NAAQS. See 70 FR 55559 

(September 22, 2005). 

The Montgomery County Area LMP, 

submitted by TDEC on June 23, 2020, is 

designed to maintain the 1997 8-hour 

ozone NAAQS within the Montgomery 

County Area through the end of the 

second 10-year portion of the 

maintenance period beyond 

redesignation. EPA is proposing to 

approve the plan because it meets all 

applicable requirements under CAA 

sections 110 and 175A. 

As a general matter, the Montgomery 

County Area LMP relies on the same
