Establishment of Class E Airspace; Circle Town, MT

AGENCY:

Federal Aviation Administration (FAA), DOT.

SUPPLEMENTARY INFORMATION:

History

On July 5, 2012, the FAA published in the Federal Register a notice of proposed rulemaking (NPRM) to establish controlled airspace at Circle Town, MT (77 FR 39651). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. The FAA received one comment from the National Business Aviation Association (NBAA).

The NBAA recommended the FAA lower some of the adjacent Class E airspace extending upward from 14,500 feet Mean Sea Level (MSL) to the east, south and west of the airport down to 1,200 feet above the surface to accommodate orderly en route descent into the airport. The NBAA is also concerned that the Minimum Instrument Flight Rules Altitude (MIA) outside the 1,200 feet above the surface would affect air traffic services into the airport. Finally, the commenter points out that extending the Class E 1,200-foot area would provide relief to Salt Lake City Air Route Traffic Control Center (ARTCC).

The FAA believes that lowering this airspace is outside the scope of this rulemaking at this time, and would not serve the immediate purpose of establishing the airspace necessary for the safety of aircraft within the Circle Town, MT, airport area.

Class E airspace designations are published in paragraph 6005, of FAA Order 7400.9V dated August 9, 2011, and effective September 15, 2011, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in that Order.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) Part 71 by establishing Class E airspace extending upward from 700 feet above the surface, at Circle Town County Airport, to accommodate IFR aircraft executing new RNAV (GPS) standard instrument approach procedures at the airport. This action is necessary for the safety and management of IFR operations.

The FAA has determined this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this regulation: (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 this 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. The FAA's authority to issue rules regarding aviation safety is found in Title 49 of the U.S. Code. Subtitle 1, Section 106 discusses 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 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 establishes controlled airspace at Circle Town County Airport, Circle Town, MT.

Environmental Review

The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA Order 1050.1E, “Environmental Impacts: Policies and Procedures,” paragraph 311a. This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist that warrant preparation of an environmental assessment.
