Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule.

SUMMARY:

This action modifies Class E airspace areas at Casper, Natrona County International Airport, Casper, WY, to facilitate vectoring of Instrument Flight Rules (IFR) traffic from en route airspace to the airport. Decommissioning of the Muddy Mountain VOR Omnidirectional Range Tactical Air Navigation (VORTAC) has made reconfiguration necessary for the safety and management of aircraft operations at the airport.

DATES:

Effective date, 0901 UTC, May 2, 2013. 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 14, 2012, the FAA published in the Federal Register a notice of proposed rulemaking (NPRM) to amend controlled airspace at Casper, WY (77 FR 67782). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received.

Class E airspace designations are published in paragraphs 6004, 6005 and 6006, respectively, of FAA Order 7400.9W dated August 8, 2012, and effective September 15, 2012, which is incorporated by reference in 14 CFR Part 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 modifying Class E airspace designated as an extension to a Class D surface area, and Class E airspace extending upward from 700 feet above the surface, to facilitate vectoring of IFR traffic from en route airspace to the airport, due to the decommissioning of the Muddy Mountain VORTAC at Casper, Natrona County International Airport, Casper, WY. This action also amends Class E en route domestic airspace extending upward from 1,200 feet above the surface by removing the exclusionary language in the regulatory text. This action enhances the safety and management of aircraft operations within the National Airspace System.

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 modifies controlled airspace at Casper, Natrona County International Airport, Casper, WY.

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.
