with the existing Butte, MT, Class E airspace area. This combined 
airspace is now designated the Butte, MT, Class E airspace area. This 
action also amends the adjacent Class E airspace at Livingston, MT, by 
providing additional controlled airspace to accommodate the development 
of new Standard Instrument Approach Procedures (SIAP) utilizing the 
Global Positioning System (GPS) at the Livingston Airport.

SUPPLEMENTARY INFORMATION

History

    On February 25, 1998, the FAA proposed to amend Title 14, Code of 
Federal Regulation, part 71 (14 CFR part 71) by removing the 
Coppertown, MT, airspace area and revising the Livingston, MT, and 
Butte, MT, Class E airspace areas (63 FR 9462). This revision provides 
the additional airspace necessary to encompass a GPS SIAP for the 
Mission Field Airport, Livingston, MT. This action also corrects two 
errors discovered in the proposal. A spelling error and an incorrect 
airport name listed in the legal description are corrected herein. 
Interested parties were invited to participate in the rulemaking 
proceeding by submitting written comments on the proposal. No comments 
were received.
    The coordinates for this airspace docket are based on North 
American Datum 83. Class E airspace areas extending upward from 700 
feet or more above the surface of the earth are published in Paragraph 
6005 of FAA Order 7400.9E, dated September 10, 1997, and effective 
September 16, 1997, which is incorporated by reference in 14 CFR 71.1. 
The Class airspace designation listed in this document will be 
published subsequently in the Order.

The Rule

    This amendment to 14 CFR part 71 modifies Class E airspace at 
Livingston, MT, and Butte, MT, while also removing Class E airspace at 
Coppertown, MT. This action combines the Coppertown, MT, Class E 
airspace area with the existing Butte, MT, Class E airspace area. This 
combined airspace is now designated the Butte, MT, Class E airspace 
area. The incorrectly named Coppertown, MT, airspace does not serve an 
airport, has no associated town, and is solely a navigational aid 
located close to Butte, MT. This amendment also provides the additional 
airspace necessary to fully encompass the GPS-A SIAP to the Mission 
Field Airport, Livingston, MT. Additionally, this rule revises the 
common airspace boundaries where Livingston, MT, and Butte, MT, 
airspace areas meet in order to better distribute the airspace serving 
the respective airports and to provide for easier cartography. The 
intended effect of this rule is designed to provide safe and efficient 
use of the navigable airspace and to promote safe flight operations 
under Instrument Flight Rule (IFR) at the Mission Field Airport and 
between the terminal and en route transition stages.
    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. 
It, therefore, (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 will not have a significant economic impact on 
a substantial number of small entities under the criteria of the 
Regulatory Flexibility Act.
