SUPPLEMENTARY INFORMATION:

History

    On Monday 11, 1999, the FAA proposed to amend Title 14, Code of 
Federal Regulations, part 71 (14 CFR part 71) by revising the Colstrip, 
MT, Class E airspace area (64 FR 12126). This revision provides the 
additional airspace necessary to encompass the new GPS Runway 6 and the 
GPS Runway 24 SIAP's to the Colstrip Airport, Colstrip, MT. This 
amendment provides a lower Class E airspace area to the west in order 
to meet current criteria standards associated with SIAP holding 
patterns. 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 7400.9F, dated September 10, 1998, and effective 
September 16, 1998, which is incorporated by reference in 14 CFR 71.1. 
The Class E 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 
Colstrip, MT, by providing the additional airspace necessary to fully 
contain new flight procedures at Colstrip Airport. 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 Rules (IFR) at the Colstrip 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.
