As part of the on-going efforts to establish area navigation routings the FAA is establishing RNAV routes to provide greater freedom to properly equipped users, and to achieve the safety and economic benefits of flying user-selected non-restrictive routings. The new RNAV routes will be identified by the letter prefix “Q” followed by a number consisting of from one to three digits. The International Civil Aviation Organization (ICAO) has allocated the “Q” prefix, along with the number set 1 through 499, for use by the U.S. for designating domestic RNAV routes.

The Proposal

The FAA is proposing an amendment to Title 14 Code of Federal Regulations (14 CFR) part 71 to establish an RNAV route within the airspace assigned to the Seattle, Los Angeles, Albuquerque, Salt Lake City and Denver Air Route Traffic Control Center (ARTCC). This route is proposed to provide a direct route from the Seattle, WA area to Phoenix, AZ, that would enhance the safety, and facilitate a more flexible and efficient use of navigable airspace for en route instrument flight rules operations.

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. Therefore, this proposed regulation: (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 Start Printed Page 25713number of small entities under the criteria of the Regulatory Flexibility Act.

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.
