14 CFR Part 71

[Docket No. FAA-2007-0060; Airspace Docket No. 07-ACE-1]


Establishment of Low Altitude Area Navigation Routes (T-Routes); 
St. Louis, MO

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This action establishes two low altitude Area Navigation 
(RNAV) routes, designated T-251 and T-272, in the St. Louis, MO, 
terminal area. T-routes are low altitude Air Traffic Service routes, 
based on RNAV, for use by aircraft that have instrument flight rules 
(IFR)-approved Global Positioning System (GPS)/Global Navigation 
Satellite System (GNSS) equipment. Minor changes to the coordinates for 
the RIVRS, IL, Intersection and the Foristell, MO, VORTAC have been 
made to correct rounding errors. The FAA is taking this action to 
enhance safety and improve the efficient use of the navigable airspace 
in the St. Louis, MO, terminal area.

DATES: Effective Date: 0901 UTC, June 5, 2008. The Director of the 
Federal Register approves this incorporation by reference action under 
1 CFR part 51, subject to the annual revision of FAA Order 7400.9 and 
publication of conforming amendments.

SUPPLEMENTARY INFORMATION: 

History

    On November 29, 2007, the FAA published in the Federal Register a 
notice of proposed rulemaking (72 FR 67588) to establish two low 
altitude Area Navigation (RNAV) routes, designated T-251 and T-272, in 
the St. Louis, MO, terminal area. Interested parties were invited to 
participate in this rulemaking effort by submitting written comments on 
the proposal. No comments were received objecting to the proposal.
    Low altitude RNAV routes are published in paragraph 6011 of FAA 
Order 7400.9R signed August 15, 2007 and effective on September 15, 
2007, which is incorporated by reference in 14

CFR 71.1. The low altitude RNAV routes 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 to establish two low altitude RNAV routes, T-251 and T-272, in 
the St. Louis, MO, terminal area. These T-routes for use by GPS/GNSS-
equipped aircraft enhance safety and facilitate the more flexible and 
efficient use of the navigable airspace for en route IFR operations 
transitioning through and around the St. Louis Class B airspace area.
    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.
    The FAA's authority to issue rules regarding aviation safety is 
found in Title 49 of the United States Code. Subtitle I, Section 106 
describes 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 the 
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 low altitude Area Navigation routes (T-routes) at St. 
Louis, MO.

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, 311b, and 311k. 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.
