RIN 2120-AA66

Amendment of R-2206 and Establishment of Restricted Areas R-
2206B, R-2206C, R-2206D, R-2206E, R-2206F, and R-2206G; Clear, AK

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This action amends restricted area R-2206 by renaming it R-
2206A and establishes six new restricted areas R-2206B, R-2206C, R-
2206D, R-2206E, R-2206F, and R-2206G, over Clear, AK. The FAA has 
determined that these actions are necessary to protect aircraft from 
the hazardous High-Intensity Radiated Field (HIRF) produced by the Long 
Range Discrimination Radar (LRDR) and segregate non-participating 
aircraft.

DATES: Effective date 0901 UTC, December 29, 2022.

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 amends an existing restricted area and establishes 
restricted areas over Clear, AK, to protect operators from activities 
deemed hazardous to nonparticipating aircraft.

History

Notice of Proposed Rulemaking

    The FAA published a notice of proposed rulemaking (NPRM) in the 
Federal Register (86 FR 11194; February 24, 2021), amending R-2206 by 
renaming it and establishing restricted areas R-2206B, R-2206C, R-
2206D, R-2206E, R-2206F, and R-2206G over Clear, AK. Interested parties 
were invited to participate in this rulemaking effort by submitting 
written comments on the proposal.

History of R-2206 and Clear Airport

    R-2206 was initially established as R-20 on January 1, 1961 (25 FR 
12174), over the Clear Air Force Station (AFS) \1\ at Clear, AK, to 
protect the National Airspace System (NAS) while a potential radiation 
hazard caused by the Ballistic Missile Early Warning System (BMEWS) was 
assessed by the United States Air Force (USAF). On May 12, 1962, the 
designation of R-2206 was amended to extend the duration for an 
indefinite period (27 FR 4553) due to ongoing concern regarding the 
radiation hazard associated with the BMEWS.
---------------------------------------------------------------------------

    \1\ On June 15, 2021, Clear AFS was renamed Clear Space Force 
Station. The renaming was part of ongoing efforts to develop the 
United States Space Force (USSF). Throughout this document, for 
continuity with the proposal and clarity, the FAA will use term 
Clear AFS.
---------------------------------------------------------------------------

    Initially established for private use by the military in support of 
the BMEWS mission, Clear Airport (PACL) is located less than a \1/2\ 
Nautical Mile (NM) from the eastern boundary of R-2206. The airport was 
leased by the Secretary of the Air Force to the State of Alaska on 
December 20, 1974. The FAA performed an airspace review and issued a 
letter of ``no objection'' to convert the airport from private to 
public use on January 20, 1976.\2\ Subsequently, the land (1,814 acres) 
on which PACL is located was declared surplus by the USAF and conveyed 
to the State of Alaska in the late 1980s. PACL has remained in its 
original location since its conversion to a public use airport.
---------------------------------------------------------------------------

    \2\ A copy of this letter is in the docket for this rulemaking.
---------------------------------------------------------------------------

    The FAA did not object to the proximity of R-2206 to the airport 
when it was converted to a public use airport because, at the time of 
conversion, there was no established standard to separate restricted 
areas and public use airports. The FAA later established that a 
restricted area must exclude airspace 1,500 feet above ground level 
(AGL) and below that is within a 3 NM radius of airports available for 
public use (``1,500AGL/3NM'') in the September 16, 1993, edition of FAA 
Order JO 7400.2, Procedures for Handling Airspace Matters.\3\ The FAA 
therefore considers the original R-2206 as excepted from the 
subsequently established ``1,500AGL/3NM'' restricted area exclusion in 
FAA Order JO 7400.2.

---------------------------------------------------------------------------

Drivers for Missile Defense Agency's (MDA) LRDR

    Section 235(a)(1) of the National Defense Authorization Act (NDAA) 
for Fiscal Year (FY) 2014 required Missile Defense Agency to deploy a 
LRDR to protect the United States against long-range ballistic missile 
threats from the Democratic People's Republic of Korea (North Korea) 
and to locate the LRDR ``at a location optimized to support the defense 
of the homeland of the United States.'' Public Law 113-66; 10 U.S.C. 
2431 (Dec. 26, 2013). Section 235(b)(1) of the NDAA for FY 2014 also 
required the Secretary of Defense to ensure the capability ``to deploy 
additional tracking and discrimination sensor capabilities to support 
the defense of the homeland of the United States from future long-range 
ballistic missile threats that emerge from Iran.''
    Section 1684 of the NDAA for FY 2016 expressed ``the sense of 
Congress that additional missile defense sensor discrimination 
capabilities are needed to enhance the protection of the United States 
homeland against potential long-range ballistic missiles from Iran 
that, according to the Department of Defense, could soon be obtained by 
Iran as a result of its active space launch program.'' Public Law 114-
92; 10 U.S.C. 2431 (Jan. 6, 2015). Moreover, Section 1684(d)(1) of the 
NDAA for FY 2016 established a December 31, 2020, deadline for the 
deployment of a defensive system.
    After a detailed evaluation of cost, schedule, and performance as 
well as other mission related factors, the Department of Defense (DoD) 
determined that Clear AFS was the preferred site for the LRDR and 
designated the USAF as the lead service for LRDR.

[[Page 66949]]

Mission of LRDR Program

    The mission of the LRDR program is to define, develop, acquire, 
test, field, and sustain the LRDR as an element of the DoD Ballistic 
Missile Defense System (BMDS) in support of the Ground-Based Midcourse 
Defense (GMO) program's Homeland Defense Capability. The LRDR will 
provide persistent long-range midcourse discrimination, precision 
tracking, and hit assessment to support the GMO capability against 
long-range missile threats originating from North Korea and Iran. LRDR 
contributes to MDA's mission of developing and deploying a layered BMDS 
to defend the United States from ballistic missile attacks of all 
ranges in all phases of flight. LRDR's improved discrimination 
capability increases the defensive capacity of the homeland defense 
interceptor inventory by enabling the conservation of ground-based 
interceptors. LRDR also supports additional DoD mission areas such as 
Space Situational Awareness and Intelligence Data Collection. Changes 
in operational posture due to the evolving threat, which would result 
in LRDR deployment with unacceptable levels of HIRF exposure for 
aviation, necessitate the requirement for additional restricted 
airspace to support LRDR's critical national defense mission at Clear 
AFS.

USAF Proposal to the FAA

    By memorandum dated September 30, 2019, the USAF submitted a 
proposal to the FAA to establish two new restricted areas in the 
vicinity of Clear AFS, to protect the NAS from the HIRF produced by the 
LRDR. The proposed restricted area requires lateral and vertical limits 
larger than the current R-2206 to support the deployment of the DoD's 
LRDR to meet increased warfighter defense and readiness postures. This 
rule maintains the existing restricted area R-2206 in its current 
configuration but renames it R-2206A, and supplements this area with 
six new restricted areas designated R-2206B, R-2206C, R-2206D, R-2206E, 
R-2206F, and R-2206G. The FAA identified the need for one of the new 
restricted areas (i.e., R-2206F) that provides an additional 1,100 feet 
of navigable airspace along Parks Highway to the Northeast of Clear, 
AK. This additional restricted area allows for a visual route following 
a known landmark during normal operations. The addition of the new 
restricted area lead the FAA to re-letter the restricted areas for a 
more logical sequence (i.e., from low to high on the west side and then 
from low to high on the east side).
    The rule applies the ``1,500AGL/3NM'' restricted area exclusion for 
PACL for the new restricted areas, with exceptions. The FAA approved a 
limited deviation from its ``1,500AGL/3NM'' restricted area exclusion 
standard, published in FAA Order JO 7400.2, paragraph 23-1-4.c., for R-
2206D and R-2206E, given the extraordinary nature of the LRDR national 
defense mission required by Congressional mandate, the limited citing 
options available to the USAF to achieve its mission, and FAA's ability 
to identify and implement airspace safety and access mitigations at 
Clear, AK.
    As previously explained, the NDAA for FY 2014 required MDA to 
deploy a LRDR ``at a location optimized to support the defense of the 
homeland of the United States.'' Public Law 113-66; 10 U.S.C. 2431 
(Dec. 26, 2013). Moreover, MDA was subsequently directed to deploy the 
system by December 31, 2020. The NDAA for FY 2016 created the LRDR 
program of record and required ``in a location optimized to support the 
defense of the homeland of the United States from emerging long-range 
ballistic missile threats from Iran.'' Public Law 114-328; 10 U.S.C. 
2431 (Dec. 23, 2016). To support implementation of this mission, the 
MDA narrowed the LRDR site selection from 50 possible locations to two 
locations in Alaska based on evaluative criteria that included, 
construction and schedule timelines in light of the NDAA mandate, 
mission assurance, impacts to existing civilian and military 
infrastructure, and other resource considerations. Of the two remaining 
sites, only Clear AFS met all of the levied LRDR requirements. The 
alternative option in Alaska, Eareckson AFS, was ruled out due to 
remote geographical concerns, which added unacceptable risk to timely 
and successful deployment as compared to Clear AFS. Moreover, the MDA 
concluded that the Clear AFS location in Central Alaska offered 
expanded engagement space necessary to fulfill the LRDR mission. This 
additional engagement space affords more visibility of hostile threat 
complexes and greater time to track, discriminate and target lethal 
incoming objects and results in a much greater probability of 
successful target intercept. The siting recommendation of Clear AFS was 
approved in 2016 by the USAF and funding for LRDR at Clear AFS was 
approved in the NDAA for FY17.\4\
---------------------------------------------------------------------------

    \4\ The FAA uploaded a graphical depiction of the restricted 
areas to the docket for this rulemaking during the NPRM phase.
---------------------------------------------------------------------------

    The FAA emphasizes that any deviations from an FAA Order is 
reserved for extraordinary circumstances. In this case, the FAA 
determined that the national defense benefits of a deviation outweigh 
the costs of any additional airspace safety and access mitigations to 
manage the safe and efficient operation of the NAS and impacts to PACL. 
The decision to deviate from FAA Order JO 7400.2 in this rulemaking 
action is not binding on future determinations by the FAA concerning 
whether to approve a deviation as each deviation is reviewed on a case-
by-case basis. The FAA will review any future requests on their merits, 
based on the facts and circumstances available at that time and 
consistent with the FAA's statutory responsibilities.

Activities Within R-2206A-G

    The activity to be performed at Clear, AK, within the restricted 
areas is Ballistic Missile Defense (BMD) of the United States. System 
testing started in early 2021 and will continue until it is fully 
integrated into the DoD BMDS. During the system testing phase, the FAA 
established Title 14 Code of Federal Regulations (CFR) 99.7, special 
security instructions (SSI), implemented as temporary flight 
restrictions, as an interim airspace mitigation to protect aviation 
from the HIRF produced by the LRDR system not covered by R-2206. LRDR 
is a unique and vital component of the BMDS and will be available 
continuously both as an early-warning sensor and as an enabler for more 
effective employment of ground-based interceptors. The LRDR design 
features high system availability and maintain-while-operate 
architecture; this ensures that LRDR will be in a continual posture to 
fight in response to real-word, no-notice events. LRDR also supports 
additional mission areas including Space Situational Awareness and 
Intelligence Data Collection.
    In routine or normal defensive posture, LRDR will operate at 
reduced HIRF levels within the restricted areas that provide for the 
``1,500AGL/3NM'' restricted area exclusion. This will be accomplished 
by enforcing main beam elevation limits in the direction of Clear 
Airport to provide a minimum of 1,500 feet AGL under the portions of 
restricted areas within 3 NM of the airport. Prescheduled maintenance 
and calibration activities will also occur during routine or normal 
posture and would require activation of the additional restricted areas 
during a few periods per week for a couple of hours at a time. These 
activities will be scheduled when expected air traffic

[[Page 66950]]

around Clear Airport is minimal, with scheduled times openly 
distributed by Notice to Air Missions (NOTAM) and other outreach 
mechanisms.
    In heightened defensive posture, MDA may require use of all the 
restricted areas to conduct missile defense or other activities in 
response to real-world events. During these periods of heightened 
defensive posture, LRDR will be activated with access to its full field 
of coverage, which may necessitate activation of all restricted areas; 
this provides LRDR access to the airspace for defensive actions within 
3NM of Clear Airport at and above 400 feet AGL. Besides conducting 
actual BMDS engagements, LRDR activities that may require temporary 
activation of all restricted areas include BMDS tests, unique 
intelligence collection activities such as new foreign space launches, 
or critical space activities such as collision avoidance involving 
manned space-flight, satellite break-ups, and satellite deorbits.

Required Coordination Between the FAA, MDA, and USSF

    The FAA, MDA, and United States Space Force (USSF) currently have a 
Letter of Agreement (LOA) in place setting forth the air traffic 
control (ATC) procedures to use while the SSI implemented as temporary 
flight restrictions are in place. The LOA establishes authorities, 
responsibilities, and procedures associated with the coordination of 
air ambulance flights or other contingencies required for aircraft to 
fly into and out of the Clear Airport and Healy River Airport (PAHV) 
during the LRDR operation.
    The FAA, MDA, and USSF are currently developing a Letter of 
Procedure (LOP) that will be effective when the rule goes into effect 
replacing the LOA now in place for the SSI implemented as temporary 
flight restrictions. This LOP will remain in place until the LRDR 
system is fully integrated into the DoD's BMDS. The LOP will address 
emergency or extraordinary events. The LOP will also address pre-
determined NOTAMs to handle the activation and scheduling of the three 
non-continuous restricted areas (R-2206D-F). The LOP will include 
procedures for handling national defense no-notice activation from 
NORAD-USNORTHCOM Command Center, as well as notification times for all 
other requests, to ensure a NOTAM and notifications to the surrounding 
areas and aviators can take place with reasonable advance notice prior 
to activation. Pre-determined actions will provide the framework for 
rapid adaptation of the special use airspace to handle extraordinary 
events. The LOP will also address the maintenance of the alert system 
discussed below. After the LRDR system is fully integrated into the 
DoD's BMDS, the FAA and the USSF will enter into a new LOP.

Impact on IFR (Instrument Flight Rules) and VFR (Visual Flight Rules) 
Terminal Ops

    In the NPRM, the FAA noted the R-2206 restricted areas would impact 
IFR routes between Anchorage and Fairbanks, Alaska, including Jet Route 
J-125, VOR Federal Airway V-436, and Area Navigation (RNAV) Route Q-41. 
The FAA identified the need for mitigations altering the current 
airway/route structure to revise the affected airways around the 
expansion of R-2206. Subsequent to the NPRM, the FAA published a rule 
for Docket No. FAA-2021-0245 in the Federal Register (87 FR 65675, 
November 1, 2022) amending J-125 and V-436. The rule amended J-125 by 
removing the route segment between the Anchorage, AK, VHF 
Omnidirectional Range/Distance Measuring Equipment (VOR/DME) and the 
Nenana, AK VOR/Tactical Air Navigation (VORTAC) navigational aids 
because adjacent air traffic service routes J-115, Q-43, and Q-
41provided the same enroute capability. The rule also amended V-436 by 
removing the airway segment between the Talkeetna, AK, VOR/DME and the 
Nenana, AK, VORTAC navigational aids and replaced it with an airway 
segment that extends between the Talkeetna VOR/DME and the Fairbanks, 
AK, VORTAC which moved the airway to transition east of the R-2206 
restricted areas. Lastly, Q-41 currently and after the effective date 
of the rule will remain as published. However, ATC currently and after 
publication will require radar surveillance in certain segments as a 
mitigation due to the proximity of the route to the current SSI 
implemented as temporary flight restrictions and the R-2206 restricted 
areas.
    Anchorage Air Route Traffic Control Center (ARTCC) published that 
requirement in its Operations Bulletin and briefed all the ARTCC air 
traffic controllers. With the establishment of the R-2206 restricted 
areas by this rule, the radar surveillance requirement for aircraft 
filing and flying the Q-41 route segment affected by the restricted 
areas will be published in the Anchorage ARTCC's Standard Operating 
Procedures (SOP) guidance replacing the Operation Bulletin.
    As addressed in the NPRM, the FAA reviewed the USAF proposal for 
impact on arrival and departure flows, Standard Terminal Arrival Route 
(STAR), Standard Instrument Departure (SID), and departure procedures, 
and identified a number procedures that needed to be revised to avoid 
the R-2206 restricted areas. The affected SIDs at Fairbanks 
International Airport were amended and published in the Flight 
Information Publication (FLIP) effective August 12, 2021. The affected 
STARs at Ted Stevens International Airport and the affected instrument 
approach procedures and obstacle departure procedure at Healy River 
Airport were amended and are being held to publish in the FLIP 
effective December 29, 2022. Amendment and publication in the FLIP of 
the affected SIDs, STARs, instrument approach procedures, and obstacle 
departure procedure listed in the NPRM ensures the IFR and VFR terminal 
operations at Fairbanks International Airport, Ted Stevens 
International Airport, and Healy River Airport are unaffected by the 
restricted areas.

United States Space Force

    The USSF was established on December 20, 2019, when the NDAA for FY 
2020 was signed into law. As part of the establishment of the USSF, the 
using agency unit proposed in the NPRM, 13th Missile Warning Squadron, 
transitioned from the Air Force Space Command within the USAF to the 
USSF and was renamed the 13th Space Warning Squadron. The USSF will 
oversee the LRDR operations at Clear AFS once the system is fully 
integrated into the DoD's BMDS. Finally, on June 15, 2021, Clear AFS 
was renamed to Clear Space Force Station (SFS).

Differences From the NPRM

    In the NPRM published for Docket No. FAA-2020-0755, the FAA 
identified an editorial error in describing the proposed altitude floor 
for restricted area R-2206C. In the preamble of the NPRM, the altitude 
floor for R-2206C was described incorrectly as 1,100 feet mean sea 
level (MSL). The correct altitude floor for R-2206C is 1,600 feet MSL. 
Although the altitude floor for R-2206C was described incorrectly in 
the preamble of the NPRM, it was described correctly in the proposed 
regulatory text of the NPRM as 1,600 feet MSL. Therefore, this rule 
retains the R-2206C designated altitudes listed in the description in 
the regulatory text as proposed.
    Also in the NPRM for Docket No. FAA-2020-0755, editorial errors in 
describing the proposed altitude floors for restricted areas R-2206B 
and R-2206D, were identified. In the preamble of the NPRM, the altitude

[[Page 66951]]

floors were described incorrectly as 1,100 feet MSL. The correct 
altitude floor for R-2206B and R-2206D is 1,000 feet MSL. Although the 
altitude floors for R-2206B and R-2206D were described incorrectly in 
the preamble of the NPRM, they were described correctly in the proposed 
regulatory text of the NPRM as 1,000 feet MSL. Therefore, this rule 
retains the R-2206B and R-2206D designated altitudes listed in the 
descriptions in the regulatory text as proposed.
    Lastly, in the NPRM for Docket No. FAA-2020-0755, the using agency 
for the restricted area descriptions in the regulatory text was listed 
as, ``Commander 13th Missile Warning Squadron, Clear, AK.'' However, as 
a result of the establishment of the USSF and the renaming of the unit 
to 13th Space Warning Squadron, as noted above, this rule corrects the 
restricted areas using agency to Commander, 13th Space Warning 
Squadron, Clear, AK.

Discussion of Comments

    The FAA received eleven comments on the NPRM. Ten of the comments 
were submitted by individuals and one comment was submitted by the 
Alaska Airmen's Association.
    The Alaska Airmen's Association and three other commenters stated 
that the proposed airspace design may be too complicated based on the 
FAA's interim approach of establishing Special Security Instructions 
(SSI) in accordance with 14 CFR 99.7, implemented as a temporary flight 
restriction, to protect aviation from the HIRF produced during the 
testing phases of the LRDR. The Alaska Airmen's Association commented 
that none of the third-party mapping applications are able to display 
correctly a graphic depiction of the current SSI implemented as 
temporary flight restrictions identified in the NOTAMs. Commenters also 
noted that without the ability to precisely determine the status (i.e., 
active or inactive) of the SSI implemented as temporary flight 
restrictions, it will likely cause inadvertent and repeated incursions 
into the temporary flight restrictions.
    The FAA acknowledged the concerns about SSI as implemented as 
temporary flight restrictions and took action to address the issues 
with the interim approach while developing this final rule. Two NOTAMs 
were published as an interim approach to protecting aircraft during the 
LRDR testing phase, one for the continuously active SSI implemented as 
temporary flight restrictions, which correlate with the designation of 
R-2206B, C, and G restricted areas and one for the non-continuously 
active SSI implemented as temporary flight restrictions, which 
correlate with designation of R-2206D-F restricted areas.
    The FAA determined the source of the confusion with these NOTAMs 
and lack of charted depictions came from the overlapping altitudes of 
the temporary flight restrictions. The overlapping altitudes of the two 
SSI implemented as temporary flight restrictions caused errors in the 
shape files that resulted in the graphical depictions of the flight 
restricted areas not being displayed on the FAA's Temporary Flight 
Restriction (TFR) website or third part charting applications. The FAA 
adjusted the overlapping altitudes of the SSI implemented as temporary 
flight restrictions and republished the NOTAMs with the changed 
altitudes on May 7, 2021. As a result, the FAA's TFR website and all 
third-party charting applications were able to display the SSI 
implemented as temporary flight restrictions correctly. Pilots have 
been able to better familiarize themselves with the SSI temporary 
flight restrictions since May 2021.
    The concerns associated with the SSI as implemented as temporary 
flight restrictions graphical depictions not displaying properly will 
not carry forward with the establishment of the new restricted areas R-
2206A-G pursuant to Part 73. The restricted areas will be depicted 
correctly on the associated aeronautical charts following the effective 
date of this rule.
    Five individual commenters expressed concerns that the proposed 
restricted areas (R-2206A-G) would lead to the closure of PACL and 
remove the ability to navigate under visual flight rules (VFR) via the 
Parks Highway (Alaska Highway 3) when the restricted areas are 
active.\5\
---------------------------------------------------------------------------

    \5\ The agency notes that one additional individual commenter 
simply expressed that adopting the proposal would make life a lot 
harder for pilots conducting VFR operations, with no further 
explanation.
---------------------------------------------------------------------------

    The FAA previously considered this issue and addressed the concern 
in a Letter of Agreement (LOA) \6\ between the FAA, MDA, and USSF. The 
procedures in the LOA requires MDA to halt its activities to allow for 
flights to access PACL. With the establishment of the restricted areas 
by this rule, the FAA, MDA, and USSF will establish a Letter of 
Procedure (LOP) to reflect the restricted areas airspace instead of the 
SSI implemented as temporary flight restrictions. To further mitigate 
impacts, the low-altitude restricted areas R-2206D-F will only be 
utilized for testing between 0200-0400 Tuesday, Thursday, and Saturday 
to support scheduled calibration. Outside of the scheduled times for 
testing, the FAA anticipates that the airspace would likely only be 
activated in the interest of the national defense of the United States 
as a result of a real world event. When the restricted areas are not 
active, pilots can land and depart PACL unrestricted.
---------------------------------------------------------------------------

    \6\ In the NPRM, the FAA referenced a Letter of Procedure being 
in place prior to the final rule. However, the proper term is Letter 
of Agreement.
---------------------------------------------------------------------------

    Also, in response to comments received during the FAA Safety Risk 
Management Panel (SRMP) requesting increased navigable airspace 
surrounding Parks Highway, the FAA, MDA, and USAF collaborated on the 
development of R-2206F and the FAA added R-2206F to the proposal. R-
2206F allows VFR navigation via the Parks Highway without impacting the 
overall design of the restricted areas. Finally, the short activation 
times for R-2206F will further mitigate and minimize impacts to pilots 
conducting such VFR operations, navigating via the Parks Highway.
    Two individual commenters expressed their concerns that instrument 
flight rules (IFR) procedures into Healy River Airport (HRR) will be 
eliminated. The FAA retained the IFR procedures into HRR and kept them 
available for use, as needed. The FAA also developed an interim 
procedure, in collaboration with the MDA, which allows for activities 
occurring within the SSI implemented as temporary flight restrictions 
to be temporarily halted, as necessary, to enable IFR flights into HRR. 
Finally, the FAA developed new, permanent HRR approach and departure 
procedures that will not be affected by the R-2206A-G restricted areas 
once they are established. The new HRR IFR approach and departure 
procedures are planned to be published in the FLIP concurrent with the 
effective date of this rule establishing the R-2206 restricted areas.
    The Alaska Airmen's Association expressed concerns that when the 
LRDR becomes operational, R-2206D-F could go active without warning, 
for a real world event. They further cited the MDA stating that for 
reasons of operational security, there can be no prior notification for 
activating the lower zones.
    At the time that the NPRM published, neither the FAA nor MDA had a 
mechanism in place to notify pilots when R-2206D-F activate outside of 
prescheduled periods. The communications coverage for real-time 
notifications by air traffic control near the Clear LRDR and PACL 
airport was deficient. Anchorage ARTCC has no

[[Page 66952]]

communications coverage and the local Flight Service Station's 
communications was intermittent. As such, without other communications 
measures in place, there was an unacceptable risk for airspace users 
flying near the LRDR area, entering the low-altitude restricted 
airspace in R-2206D-F while it was active. Accordingly, to overcome 
this problem, the FAA, again, in collaboration with the MDA, 
implemented an actionable and timely notification system that is 
currently operational. The system includes a dedicated frequency 
(133.25 VHF) and a visual warning light with daytime and nighttime 
patterns. The dedicated frequency continually broadcasts a message to 
aviators on the status of the SSI implemented as temporary flight 
restrictions currently and will for the restricted areas established by 
this rule. The transmission is audible from the PACL for aircraft 
holding short of all runway entry points; the PACL north ramp for 
helicopter operations by the Bureau of Land Management; while flying 
northbound from Healy River Airport (PAHV) over the city of Ferry, AK; 
and while flying southbound from Nenana Airport (PANN) along the Parks 
Highway. The visual warning light is visible, day and night, while 
flying southbound from PANN airport between 1,000 feet and 2,600 feet 
AGL and along the Parks Highway. It is also visible while flying toward 
PACL between 500 feet and 1,500 feet AGL at 4 NM from headings of 
090[deg], 120[deg], and 180[deg]; and while flying towards PACL between 
500 feet and 1,500 feet AGL at 5.1 NM and 7.3 NM, respectively, from a 
heading of 360[deg]. The warning light is not visible from the surface; 
however, aircraft on the ground are encouraged to use the dedicated 
frequency, 133.25 VHF, for restricted area status updates. 
Additionally, the Alaska Department of Transportation installed 4 signs 
on PACL at each of the 3 runway hold short lines and 1 at the north 
ramp, where helicopters depart, to notify pilots, prior to departure, 
of the dedicated alerting frequency that is broadcasting the SSI 
implemented as temporary flight restrictions status currently and the 
restricted areas established by this rule status as further 
encouragement.

The Rule

    This action amends 14 CFR part 73 by renaming R-2206 to R-2206A and 
establishing 6 new restricted areas R-2206B, R-2206C, R-2206D, R-2206E, 
R-2206F, and R-2206G, over the Clear SFS at Clear, AK. The FAA has 
determined that the action is necessary to protect aircraft from the 
hazardous HIRF produced by the MDA's LRDR and segregate non-
participating aircraft. Full legal descriptions of the restricted areas 
are contained in ``The Amendment'' section as set forth below.
    R-2206A: R-2206 is amended by renaming it R-2206A. There is no 
change to the boundaries as established under R-2206. The designated 
altitudes extend upward from the surface to 8,800 feet MSL. R-2206A is 
active continuously.
    R-2206B: R-2206B is established west of PACL, fanning clockwise 
from the southwest to the northwest, excluding the portion within R-
2206A, with the eastern boundary located 3 NM west of PACL. The 
designated altitudes extend upward from 1,000 feet MSL to, but not 
including 1,600 feet MSL. R-2206B is active continuously.
    R-2206C: R-2206C is established west of PACL, fanning clockwise 
from the southwest to the northwest, excluding the portion within R-
2206A, with the eastern boundary located 3 NM west of PACL. The 
designated altitudes extend upward from 1,600 feet MSL to 32,000 feet 
MSL. R-2206C is active continuously.
    R-2206D: R-2206D is established northwest of PACL, fanning 
clockwise from the northwest to north, excluding the portion within R-
2206A, with the eastern boundary located \1/2\ NM west of PACL. The 
designated altitudes extend upward from 1,000 feet MSL to, but not 
including 1,600 feet MSL. R-2206D activation times are 0200-0400 local 
time, Tuesday, Thursday, and Saturday; other times by NOTAM.
    R-2206E: R-2206E is established north of PACL, fanning clockwise 
from the northwest to the northeast, excluding the portion within R-
2206A, with the eastern boundary located \1/2\ NM west of PACL. The 
designated altitudes extend upward from 1,600 feet MSL to, but not 
including 2,100 feet MSL. R-2206E activation times are 0200-0400 local 
time, Tuesday, Thursday, and Saturday; other times by NOTAM.
    R-2206F: R-2206F is established northeast of PACL, enabling VFR 
aircraft to transition along Alaska Highway 3 (the Parks Highway) with 
the southern boundary located 3 NM north of PACL. The designated 
altitudes extend upward from 2,100 feet MSL to 3,200 feet MSL. R-2206F 
activation times are 0200-0400 local time, Tuesday, Thursday, and 
Saturday; other times by NOTAM.
    R-2206G: R-2206G is established north of PACL, fanning clockwise 
from the northwest to the northeast, excluding the portions within R-
2206A and R-2206F, with the eastern boundary located \1/2\ NM west of 
PACL. The designated altitudes extend upward from 2,100 feet MSL to 
32,000 feet MSL. R-2206G is active continuously.

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 
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 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 rulemaking action of renaming 
restricted area R-2206 to R-2206A and establishing six new restricted 
areas R-2206B, R-2206C, R-2206D, R-2206E, R-2206F, and R-2206G, over 
Clear, AK qualifies for categorical exclusion under the National 
Environmental Policy Act (42 U.S.C. 4321 et seq.) and its implementing 
regulations at 40 CFR part 1500, and in accordance with FAA Order 
1050.1F, Environmental Impacts: Policies and Procedures, paragraph 5-
6.5a, which categorically excludes from further environmental impact 
review rulemaking actions that designate or modify classes of airspace 
areas, airways, routes, and reporting points (see 14 CFR part 71, 
Designation of Class A, B, C, D, and E Airspace Areas; Air Traffic 
Service Routes; and Reporting Points). As such, this rulemaking action 
is not expected to cause or result in any potentially significant 
environmental impacts. In accordance with FAA Order 1050.1F, paragraph 
5-2 regarding Extraordinary Circumstances, the FAA has reviewed this 
rulemaking action for factors and circumstances in which a normally 
categorically excluded action may have a significant environmental 
impact requiring further analysis, and has determined that no 
extraordinary circumstances exist warranting preparation of an 
environmental assessment or environmental impact study.
    On May 7, 2021, the MDA, as the lead agency, announced the 
availability of its

[[Page 66953]]

Final Environmental Impact Statement (EIS) for the Long Range 
Discrimination Radar (LRDR) located at Clear Air Force Station (CAFS), 
Alaska. 86 FR 24599-24600. The FAA and the Department of the Air Force 
(DAF) are cooperating agencies to the Final EIS. The MDA's EIS analyzed 
the operational impacts of the LRDR, including airspace restrictions 
necessary to ensure that aircraft would not encounter high intensity 
radiation fields (HIRF) resulting from the LRDR operations that exceed 
FAA's HIRF certification standards for aircraft electrical and 
electronic systems. The proposed airspace restrictions include 
expansion of the existing restricted area (R-2206) at CAFS by adding 
six new restricted areas. The preferred alternative is to operate the 
LRDR continuously under the changed operational concept and to 
implement the associated proposed airspace restrictions as described in 
the Proposed Action analyzed in the Final EIS.
    On June 24, 2021, the MDA as lead agency, with the DAF as a 
cooperating agency, issued a joint Record of Decision (ROD) to 
implement changes in operational concept for the LRDR at CAFS, Alaska. 
86 FR 33240. The ROD includes modification of the LRDR operational 
requirements and procedures to reflect continuous operations in 
response to emerging threats. The action enables the MDA to meet its 
congressional mandate to fully support the primary mission of the 
layered Missile Defense System (MDS) to provide continuous and precise 
tracking and discrimination of long-range missile threats launched 
against the United States. The FAA is a cooperating agency on the LRDR 
CAFS EIS because it has special expertise and jurisdiction by law, 
pursuant to 49 U.S.C. 40101 et seq., for aviation and regulation of air 
commerce in the interests of aviation safety and efficiency. The MDA 
requested that the FAA, as a cooperating agency, consider and adopt, in 
whole or in part, the Final EIS as the required NEPA documentation to 
support FAA decisions on the establishment of restricted areas. The 
airspace associated with the proposed action and alternative lies 
within the jurisdiction of the FAA Anchorage Air Route Traffic Control 
Center. FAA established 6 new restricted areas and made related changes 
in airspace management.
    On July 6, 2021, the FAA adopted the airspace portion of the MDA's 
EIS per FAA's policy for Adoption of Other Agencies' NEPA Documents in 
FAA Order 1050.1F, Paragraph 8-2. On August 23, 2021, the FAA issued a 
Notice of Availability for its adoption of MDA's Final EIS for LRDR 
Operations, Clear Air Force Station, Alaska (CAFS), and Record of 
Decision for FAA actions to accommodate testing and operation of the 
LRDR at CAFS under the MDA's Modified Operational Concept; Adoption of 
the Missile Defense Agency's Final Environmental Impact Statement for 
Long Range Discrimination Radar (LRDR) Operations, Clear Air Force 
Station, Alaska (CAFS), and Record of Decision for Federal Aviation 
Administration Actions to Accommodate Testing and Operation of the LRDR 
at CAFS under the Missile Defense Agency's Modified Operational 
Concept, which addresses the FAA's decision to establish additional 
restricted areas to protect aviation from HIRF generated during the 
LRDR testing and operation, implement temporary flight restrictions 
until the restricted areas are in effect, and make changes to federal 
airways and instrument flight procedures to accommodate the new 
restricted areas (86 FR 47195, August 23, 2021).
