An informal docket may also be examined during normal business hours at the office of the Western Service Center, Operations Support Group, Federal Aviation Administration, 2200 South 216th St., Des Moines, WA 98198. Background In a final rule published on February 14, 1962, the FAA established restricted area R–7001 (27 FR 1355) at Guernsey, WY, in order to provide special use airspace for the hazardous artillery firing conducted by Army National Guard (Army) units during its annual summer training periods. Since R–7001 was established, the Army’s activities and technologies have changed, requiring amendments to R–7001 and the establishment of new restricted areas to ensure non-participating aircraft are protected from hazardous activity in the National Airspace System (NAS). Currently, the restricted areas at Guernsey, WY, are designated as R–7001A, R–7001B, and R–7001C. In August 1979, the FAA divided R–7001 vertically into R–7001A and R–7001B (44 FR 34114; June 14, 1979) to provide VerDate Sep<11>2014 18:38 Mar 03, 2021 Jkt 253001 greater flexibility for military training and divide the airspace vertically to allow non-participating aircraft access to unused portions of the airspace, when not in use. The FAA established R–7001C in February 1985 (50 FR 6156; February 14, 1985) to protect the NAS from the high angle fire of various weapons and permit maximum firing capability of these weapons. In order to address the advances in weapons systems capabilities and provide the United States Army the ability to conduct longer range artillery training, several Controlled Firing Areas (CFA) were established for use in the same location as R–7002A, R–7002 B, and R–7002C. The current configuration of restricted areas and CFAs can no longer support the full capability of the artillery in part, due to the operational limitations of the CFAs. Camp Guernsey Joint Training Center hosts several exercises throughout the year. During these exercises, 155mm artillery, M270 Multiple Launch Rocket System (MLRS), and M142 High Mobility Artillery Rocket System (HIMARS) are fired. Additionally, Guernsey, WY is the closest restricted area complex to F.E. Warren Air Force Base, WY. The development of these new restricted areas would accommodate the United States Air Force’s activities and provide for its ability to train locally for air-toground firing from helicopters, and the associated Weapon Danger Zones (WDZ). Finally, while conducting the evaluation of the restricted areas at Guernsey, WY, the FAA noted that R– 7001B and R–7001C were inadvertently overlapping airspace. The ceiling of R– 7001B stops at 23,500 feet mean sea level (MSL) and the floor of R–7001C starts at 23,500 feet MSL. This is an error and the proposed amendment would provide the necessary vertical separation between the two restricted airspace areas. The Proposal The FAA is proposing an amendment to Title 14 Code of Federal Regulations (14 CFR) part 73 to amend restricted area R–7001C and establish R–7001D, R–7002A, R–7002B, and R–7002C at Guernsey, WY. The FAA is proposing this action at the request of the WYARNG activities and due to correct an inadvertent error. Full legal descriptions are in the ‘‘The Proposed Amendment’’ section of this NPRM. The proposed restricted areas are described below. R–7001C: R–7001C would retain the current boundaries, but the floor of the restricted area would begin at 23,501 PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 12553 feet MSL. No other changes would be made to the legal description. R–7001D: R–7001D would be established above R–7001C and would have the same boundaries as the existing restricted area. The altitudes would be from 30,001 to 45,000 feet MSL. Operations would be limited to 20 days a year. R–7002A: R–7002A would be established north of, and sharing its southern boundary with R–7001A, R–7001B, and R–7001C. The altitudes would be from the surface to 23,500 feet MSL. Operations would be limited to 20 days a year. R–7002B: R–7002B would be established on the southeast border, and sharing its northern boundary with R–7001A, R–7001B, and R–7001C. The altitudes would be from the surface to 23,500 feet MSL. Operations would be limited to 20 days a year. R–7002C: R–7002C would be established west of, and sharing its eastern border with R–7001A, R–7001B, and R–7001C. The altitudes would be from the surface to 23,500 feet MSL. Operations would be limited to 20 days a year. 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.

Background

    In a final rule published on February 14, 1962, the FAA established 
restricted area R-7001 (27 FR 1355) at Guernsey, WY, in order to 
provide special use airspace for the hazardous artillery firing 
conducted by Army National Guard (Army) units during its annual summer 
training periods. Since R-7001 was established, the Army's activities 
and technologies have changed, requiring amendments to R-7001 and the 
establishment of new restricted areas to ensure non-participating 
aircraft are protected from hazardous activity in the National Airspace 
System (NAS). Currently, the restricted areas at Guernsey, WY, are 
designated as R-7001A, R-7001B, and R-7001C. In August 1979, the FAA 
divided R-7001 vertically into R-7001A and R-7001B (44 FR 34114; June 
14, 1979) to provide greater flexibility for military training and 
divide the airspace vertically to allow non-participating aircraft 
access to unused portions of the airspace, when not in use. The FAA 
established R-7001C in February 1985 (50 FR 6156; February 14, 1985) to 
protect the NAS from the high angle fire of various weapons and permit 
maximum firing capability of these weapons.
    In order to address the advances in weapons systems capabilities 
and provide the United States Army the ability to conduct longer range 
artillery training, several Controlled Firing Areas (CFA) were 
established for use in the same location as R-7002A, R-7002 B, and R-
7002C. The current configuration of restricted areas and CFAs can no 
longer support the full capability of the artillery in part, due to the 
operational limitations of the CFAs. Camp Guernsey Joint Training 
Center hosts several exercises throughout the year. During these 
exercises, 155mm artillery, M270 Multiple Launch Rocket System (MLRS), 
and M142 High Mobility Artillery Rocket System (HIMARS) are fired. 
Additionally, Guernsey, WY is the closest restricted area complex to 
F.E. Warren Air Force Base, WY. The development of these new restricted 
areas would accommodate the United States Air Force's activities and 
provide for its ability to train locally for air-to-ground firing from 
helicopters, and the associated Weapon Danger Zones (WDZ).
    Finally, while conducting the evaluation of the restricted areas at 
Guernsey, WY, the FAA noted that R-7001B and R-7001C were inadvertently 
overlapping airspace. The ceiling of R-7001B stops at 23,500 feet mean 
sea level (MSL) and the floor of R-7001C starts at 23,500 feet MSL. 
This is an error and the proposed amendment would provide the necessary 
vertical separation between the two restricted airspace areas.

The Proposal

    The FAA is proposing an amendment to Title 14 Code of Federal 
Regulations (14 CFR) part 73 to amend restricted area R-7001C and 
establish R-7001D, R-7002A, R-7002B, and R-7002C at Guernsey, WY. The 
FAA is proposing this action at the request of the WYARNG activities 
and due to correct an inadvertent error. Full legal descriptions are in 
the ``The Proposed Amendment'' section of this NPRM.
    The proposed restricted areas are described below.
    R-7001C: R-7001C would retain the current boundaries, but the floor 
of the restricted area would begin at 23,501 feet MSL. No other changes 
would be made to the legal description.
    R-7001D: R-7001D would be established above R-7001C and would have 
the same boundaries as the existing restricted area. The altitudes 
would be from 30,001 to 45,000 feet MSL. Operations would be limited to 
20 days a year.
    R-7002A: R-7002A would be established north of, and sharing its 
southern boundary with R-7001A, R-7001B, and R-7001C. The altitudes 
would be from the surface to 23,500 feet MSL. Operations would be 
limited to 20 days a year.
    R-7002B: R-7002B would be established on the southeast border, and 
sharing its northern boundary with R-7001A, R-7001B, and R-7001C. The 
altitudes would be from the surface to 23,500 feet MSL. Operations 
would be limited to 20 days a year.
    R-7002C: R-7002C would be established west of, and sharing its 
eastern border with R-7001A, R-7001B, and R-7001C. The altitudes would 
be from the surface to 23,500 feet MSL. Operations would be limited to 
20 days a year.

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.
