End Further Info End Preamble Start Supplemental Information



On May 7, 2007, the FAA published in the Federal Register a notice of proposed rulemaking to establish a direct route from the Seattle Area to the Phoenix, AZ, area (72 FR 25712). Interested parties were invited to participate in this rulemaking effort by submitting written comments on this proposal to the FAA. No comments were received.

High altitude area navigation routes are published in paragraph 2006 of FAA Order 7400.9P dated September 1, 2006 and effective September 15, 2006, which is incorporated by reference in 14 CFR 71.1. The area navigation routes listed in this document will be published subsequently in the Order. Start Printed Page 40717

The Rule

This action amends 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 provides a direct route from the Seattle, WA area to Phoenix, AZ, and facilitates a more flexible and efficient use of navigable airspace for en route instrument flight rules operations.

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. Therefore, this 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 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

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.
