The FAA is proposing an amendment to Title 14, Code of Federal Regulations


### 54860 Federal Register / Vol. 77, No. 173 / Thursday, September 6, 2012 / Proposed Rules

(14 CFR) part 71 to establish VOR Federal airway V–629 near Las Vegas, NV. The proposed route would extend between a point approximately 26 NM northeast of the Goffs, CA, VORTAC and the Boulder City, NV, VORTAC. The purpose of the proposed route is to increase the efficiency of the NAS in the vicinity of Las Vegas and to provide positive course guidance for aircraft navigating in an area of marginal radar
coverage.

VOR Federal airways are published in paragraph 6010 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 airway listed in this document would be subsequently published in the Order.

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 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 modifies the route structure as required to preserve the safe and efficient flow of air traffic in the Las Vegas, NV, area.

Environmental Review

This proposal will be subject to an environmental analysis in accordance with FAA Order 1050.1E, ‘‘Environmental Impacts: Policies and Procedures,’’ prior to any FAA final regulatory action. List of Subjects in 14 CFR Part 71

Airspace, Incorporation by reference, Navigation (air). The Proposed Amendment

In consideration of the foregoing, the Federal Aviation Administration proposes to amend 14 CFR part 71 as follows:

**PART 71—DESIGNATION OF CLASS A, B, C, D, AND E AIRSPACE AREAS; AIR**  **TRAFFIC SERVICE ROUTES; AND REPORTING POINTS** 

1. The authority citation for part 71 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40103, 40113, 40120; E.O. 10854, 24 FR 9565, 3 CFR, 1959– 1963 Comp., p. 389.

**§ 71.1 [Amended]**

2. The incorporation by reference in 14 CFR 71.1 of FAA Order 7400.9V, Airspace Designations and Reporting Points, Dated August 9, 2011, and effective September 15, 2011, is amended as follows:

Paragraph 6010 Domestic VOR Federal airways.

V–629 [New]

From INT Goffs, CA, 033 ° (T)/018 ° (M) and the Boulder City, NV, 182 ° (T)/167 ° (M) radials to Boulder City.

**Proposed Modification of VOR Federal Airway V–170 in the Vicinity of Devils**  **Lake, ND**

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  This action proposes to modify VHF Omnidirectional Range (VOR) Federal airway V–170 between Devils Lake, ND (DVL), and Jamestown, ND (JMS). The FAA is proposing this action to ensure the airway provides the necessary clearance from the western boundary of the newly established restricted area R–5402, Devils Lake, ND, to support non-radar separation requirements when the restricted area is active.
