14 CFR Part 71

[Docket No. FAA-2013-0258; Airspace Docket No. 13-ANM-12]


Modification of Class D and E Airspace; Twin Falls, ID

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: This action modifies Class E airspace at Twin Falls Joslin 
Field-Magic Valley Regional Airport, Twin Falls, ID, to accommodate 
aircraft using the Navigation (RNAV) Global Positioning System (GPS) 
and the Instrument Landing System (ILS) or Localizer (LOC) standard 
instrument approach procedures at the airport. This action also updates 
the geographic coordinates of the airport and navigation aid for the 
respective Class E airspace areas, as well as corrects the airport name 
to Twin Falls Joslin Field-Magic Valley Regional Airport. Reference to 
Class D airspace, omitted from the Title in the notice of proposed 
rulemaking is included in this rule. This improves the safety and 
management of Instrument Flight Rules (IFR) operations at the airport.

DATES: Effective date, 0901 UTC, October 17, 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.

Administration, Operations Support Group, Western Service Center, 1601

SUPPLEMENTARY INFORMATION:

History

    On May 1, 2013, the FAA published in the Federal Register a notice 
of proposed rulemaking (NPRM) to modify controlled airspace at Twin 
Falls Joslin Field-Magic Valley Regional Airport, Twin Falls, ID (78 FR 
25406). Interested parties were invited to participate in this 
rulemaking effort by submitting written comments on the proposal to the 
FAA. No comments were received. Subsequent to publication, the FAA 
found that the Class D airspace reference was omitted from the Title, 
and is added in this rule to note the airport's name change. Except for 
editorial changes, and the changes made above, this rule is the same as 
published in the NPRM.
    Class D and E airspace designations are published in paragraphs 
5000, 6002, 6004 and 6005, respectively, of FAA Order 7400.9W dated 
August 8, 2012, and effective September 15, 2012, which is incorporated 
by reference in 14 CFR 71.1. The Class D and 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 extending upward from 700 feet 
above the surface and 1,200 feet above the surface at Twin Falls Joslin 
Field-Magic Valley Regional Airport, Twin Falls, ID, to accommodate 
aircraft using the RNAV (GPS) and the ILS or LOC standard instrument 
approach procedures at the airport. Also, the geographic coordinates of 
the airport and Twin Falls VHF Omni-Directional Radio Range Tactical 
Air Navigation Aid (VORTAC) is updated to coincide with the FAA's 
aeronautical database for the respective Class E airspace areas. This 
action is necessary for the safety and management of IFR operations. 
The airport formerly called Twin Falls-Sun Valley Regional Airport, 
Joslin Field or Joslin Field-Magic Valley Regional is renamed Twin 
Falls Joslin Field-Magic Valley Regional Airport under its respective 
Class D and E airspace areas.
    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 
only affects air traffic procedures and air navigation, it is certified 
this rule, when promulgated, does 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 Twin Falls Joslin Field-Magic Valley Regional 
Airport, Twin Falls, ID.

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.
