Amendment of Class E Airspace; Riverton, WY

AGENCY: Federal Aviation Administration (FAA), DOT.

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

Comments for inclusion in the Rules Docket must be received on or

before November 30, 1998.

SUPPLEMENTARY INFORMATION:

The Riverton, WY, Class E surface airspace was originally effective

on a part-time basis. The commissioning of the ASOS coupled with the

need for a continuous surface area exist for the Riverton Regional

Airport. This amendment changes the legal airspace description from

part-time to continuous, thereby reflecting actual desired operations.

The intended effect of this rule is designed to provide for the safe

and efficient use of the navigable airspace at Riverton, WY. The

boundaries of the airspace remain the same.

The area will be depicted on aeronautical charts for pilot

reference. The coordinates for this airspace docket are based on North

American Datum 83. Class E airspace designated as a surface area for an

airport are published in Paragraph 6002 of FAA Order 7400.9F dated

September 10, 1998, and effective September 16, 1988, 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 Direct Final Rule Procedure

The FAA anticipates that this regulation will not result in adverse

or negative comment, and, therefore, issues it as a direct final rule.

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.

Unless a written adverse or negative comment or a written notice of

intent to submit an adverse or negative comment is received within the

comment period, the regulation will become effective on the date

specified above. After the close of the comment period, the FAA will

publish a docket in the Federal Register indicating that no adverse or

negative comments were received and confirming the date on which the

final rule will become effective. If the FAA does receive, within the

comment period, an adverse or negative comment, or written notice of

intent to submit such a comment, a document withdrawing the direct

final rule will be published in the Federal Register, and a notice of

proposed rulemaking may be published with a new comment period.

Comments Invited

Although this action is in the form of a direct final rule, and was

not preceded by a notice of proposed rulemaking, interested persons are

invited to comment on this rule by submitting such written data, views,

or arguments as they may desire. Communications should identify the

Rules Docket Number and be submitted in triplicate to the address

specified under the caption ADDRESSES. All communications received on

or before the closing date for comments will be considered, and this

rule may be amended or withdrawn in light of the comments received.

Factual information that supports the commenter's ideas and suggestions

are extremely helpful in evaluating the effectiveness of this action

and determining whether additional rulemaking action would be needed.

Comments are specifically invited on the overall regulatory,

economic, environmental, and energy aspects of the rule that might

suggest a need to modify the rule. All comments submitted will be

available, both before and after the closing date for comments, in the

Rules Docket for examination by interested persons. A report that

summarizes each FAA-public contact concerned with the substance of this

action will be filed in the Rules Docket.

Commenters wishing the FAA to acknowledge receipt of their comments

submitted in response to this rule must submit a self-addressed,

stamped postcard on which the following statement is made: ``Comments

to Docket No. 98-ANM-15.'' The postcard will be date stamped and

returned to the commenter.

Agency Findings

The regulations adopted herein will not have substantial direct

effects on the States, on the relationship between the national

government and the states, or on the distribution of power and

responsibilities among the various levels of government. Therefore, in

accordance with Executive Order 12612, it is determined that this final

rule does not have sufficient federalism implications to warrant the

preparation of a Federalism Assessment.

The FAA has determined that this regulation is noncontroversial and

unlikely to result in adverse or negative comments. For the reasons

discussed in the preamble, I certify that 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 these routine matters will only affect

air traffic procedures and air navigation. It is certified that these

proposed rules will not have significant economic impact on a

substantial number of small entities under the criteria of the

Regulatory Flexibility Act.
