SUPPLEMENTARY INFORMATION:

History

    On April 15, 2009, the FAA published in the Federal Register a 
notice of proposed rulemaking to establish additional controlled 
airspace at Twin Falls, ID (74 FR 17441). 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 paragraph 6005 of 
FAA Order 7400.9S signed October 3, 2008, and effective October 31, 
2008, 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 amending the Class E airspace at Twin Falls, ID. Additional 
controlled airspace is necessary to accommodate IFR aircraft executing 
a new VOR approach procedure at Twin Falls Joslin Field--Magic Valley 
Regional, Twin Falls, ID.
    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 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 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 establishes 
additional controlled airspace at Twin Falls Joslin Field--Magic Valley 
Regional, Twin Falls, ID.
