SUPPLEMENTARY INFORMATION:

History

On April 30, 2010, the FAA published in the Federal Register a notice of proposed rulemaking to establish Class D airspace for San Marcos Municipal Airport, San Marcos, TX (75 FR 22712) Docket No. FAA-2010-0406. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. Class D airspace designations are published in paragraph 5000 of FAA Order 7400.9T signed August 27, 2009, and effective September 15, 2009, which is incorporated by reference in 14 CFR part 71.1. The Class D airspace designations listed in this document will be published subsequently in the Order.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) Part 71 by establishing Class D airspace at San Marcos, TX. Establishment of an air traffic control tower at San Marcos Municipal Airport has made this action necessary for the safety and management of IFR operations at the airport. Also, a minor change has been made in the amendatory language for the airport descriptor, changing from San Marcos Municipal Airport, TX, to San Marcos, TX.

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, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

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 of 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 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 establishes controlled airspace at San Marcos Municipal Airport, San Marcos, TX. With the exception of editorial changes, and the changes described above, this rule is the same as that proposed in the NPRM.
