This action proposes to modify Class E airspace at Converse County Airport, Douglas, WY. After a review of the airspace, the FAA found it necessary to modify the airspace to enhance the safety and management of Instrument Flight Rules (IFR) operations for Standard Instrument Approach Procedures (SIAPs) at the airport and to address inaccuracy identified by FAA Airspace Policy and Support that V-19, which is no longer located in the area, is used in the legal description of the airspace.

SUPPLEMENTARY INFORMATION:

Authority for This Rulemaking

    The FAA's authority to issue rules regarding aviation safety is 
found in Title 49 of the U.S. Code. Subtitle 1, Section 106, describes 
the authority for 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 the 
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 would amend controlled airspace at Converse County Airport, 
Douglas, WY.

Comments Invited

    Interested parties are invited to participate in this proposed 
rulemaking by submitting such written data, views, or arguments, as 
they may desire. Comments that provide the factual basis supporting the 
views and suggestions presented are particularly helpful in developing 
reasoned regulatory decisions on the proposal. Comments are 
specifically invited on the overall regulatory, aeronautical, economic, 
environmental, and energy-related aspects of the proposal. 
Communications should identify both docket numbers and be submitted in 
triplicate to the address listed above. Commenters wishing the FAA to 
acknowledge receipt of their comments on this notice must submit with 
those comments a self-addressed, stamped postcard on which the 
following statement is made: ``Comments to Docket No. FAA-2015-1089; 
Airspace Docket No. 15-ANM-11.'' The postcard will be date/time stamped 
and returned to the commenter.

Availability and Summary of Documents Proposed for Incorporation by 
Reference

    This document proposes to amend FAA Order 7400.9Y, Airspace 
Designations and Reporting Points, dated August 6, 2014, and effective 
September 15, 2014. FAA Order 7400.9Y is publicly available as listed 
in the ADDRESSES section of this proposed rule. FAA Order 7400.9Y lists 
Class A, B, C, D, and E airspace areas, air traffic service routes, and 
reporting points.

The Proposal

    The FAA is proposing an amendment to Title 14 Code of Federal 
Regulations (14 CFR) Part 71 by modifying Class E airspace extending 
upward from 700 feet above the surface at Converse County Airport, 
Douglas, WY. The airspace would be modified to within a 4-mile radius 
of Converse County Airport, with a segment extending from the 4-mile 
radius to the 7-mile radius east to southwest of the airport, and a 
segment extending from the 4-mile radius to 7 miles northwest of the 
airport. The geographic coordinates of the airport would be updated to 
coincide with the FAA's aeronautical database. The lateral boundary for 
that airspace extending from 1,200 feet above the surface would be 
defined utilizing latitudinal and longitudinal reference points instead 
of Federal airway V-19, and would not change the lateral boundaries or 
operating requirements of the 1,200 foot airspace. This action is 
necessary for the safety and management of IFR operations for SIAPs at 
the airport.
    Class E airspace designations are published in paragraph 6005 of 
FAA Order 7400.9Y, dated August 6, 2014, and effective September 15, 
2014, which is incorporated by reference in 14 CFR 71.1. The Class E 
airspace designations listed in this document will be published 
subsequently in the Order.

Regulatory Notices and Analyses

    The FAA has determined this proposed regulation only involves an 
established body of technical regulations for which frequent and 
routine amendments are necessary to keep them operationally current. 
Therefore, this proposed 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 proposed rule, when 
promulgated, would not have a significant economic impact on a 
substantial number of small entities under the criteria of the 
Regulatory Flexibility Act.

Environmental Review

    This proposal will be subject to an environmental analysis in 
accordance with FAA
    Order 1050.1E, ``Environmental Impacts: Policies and Procedures'' 
prior to any FAA final regulatory action.
