# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Final rule.

# SUMMARY:

This rule establishes a Class E airspace area extending upward from 700 feet above the surface at Potosi, MO. The effect of this rule is to provide appropriate controlled Class E airspace for aircraft departing from and executing instrument approach procedures to Potosi Washington County Airport, MO and to segregate aircraft using instrument approach procedures in instrument conditions from aircraft operating in visual conditions.

# DATES:

# SUPPLEMENTARY INFORMATION:

## History

                    On Friday, December 22, 2006, the FAA proposed to amend part 71 of the Federal Aviation Regulations (14 CFR part 71) to establish Class E airspace at Potosi, MO (71 FR 76954). The proposal was to establish a Class E5 airspace area to bring Potosi, MO airspace into                           ( print page 8268)                        compliance with FAA directives. Interested parties were invited to participate in this rulemaking proceeding by submitting written comments on the proposal to the FAA. No comments objecting to the proposal were received.                

## The Rule

This rule amends Title 14 Code of Federal Regulations part 71 by establishing a Class E airspace area extending upward from 700 feet above the surface at Potosi Washington County Airport, MO. The establishment of Area Navigation (RNAV) Global Positioning System (GPS) Instrument Approach Procedures (IAP) to Runways 2 and 20 have made this action necessary. The intended effect of this action is to provide adequate controlled airspace for Instrument Flight Rules operations at Potosi Washington County Airport, MO. The area will be depicted on appropriate aeronautical charts.

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 7400.9P, Airspace Designations and Reporting Points, dated September 1, 2006, and effective September 15, 2006, which is incorporated by reference in 14 CFR 71.1. of the same Order. The Class E airspace designation listed in this document will be published subsequently in the Order.  

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. 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 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.  

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 since it contains aircraft executing instrument approach procedures to Potosi Washington County Airport, MO.
