Background In a final rule published on February 14, 1962, the FAA established restricted area R7001 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 R7001
was established, the Armys activities and technologies have changed, requiring amendments to R7001 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 R7001A, R7001B, and R7001C. In August 1979, the FAA divided R7001
vertically into R7001A and R7001B
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 R7001C 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 R7002A, R7002 B, and R7002C. 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 Forces 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 R7001C were inadvertently overlapping airspace. The ceiling of R
7001B stops at 23,500 feet mean sea level MSL and the floor of R7001C
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 R7001C and establish R7001D, R7002A, R7002B, and R7002C 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.
R7001C: R7001C 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.
R7001D: R7001D would be established above R7001C 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.
R7002A: R7002A would be established north of, and sharing its southern boundary with R7001A, R7001B, and R7001C. The altitudes would be from the surface to 23,500 feet MSL. Operations would be limited to 20
days a year.
R7002B: R7002B would be established on the southeast border, and sharing its northern boundary with R7001A, R7001B, and R7001C. The altitudes would be from the surface to 23,500 feet MSL. Operations would be limited to 20 days a year.
R7002C: R7002C would be established west of, and sharing its eastern border with R7001A, R7001B, and R7001C. 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.
