Persons interested in being placed on a mailing list for future NPRM’s should contact the FAA’s Office of Rulemaking, (202) 267–9677, to request a copy of Advisory circular No. 11–2A, Notice of Proposed Rulemaking distribution System, which describes the application procedure. The Proposal

The FAA is considering an amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 to amend Class D airspace, and Class E surface area airspace at Tri Cities Regional Airport, Tri-Cities, TN. Both the Class D airspace area and Class E surface area airspace would be reduced from a 6.8- mile radius of the airport to within a 4.3-mile radius of the airport.

The FAA found it necessary to establish Class E airspace designated as an extension to a Class D surface area at Tri-Cities Airport because removal of the previous airspace configuration caused congestion for pilots traveling to/from two neighboring airports, Edwards Heliport and Johnson City Airport (see 78 FR 7993, February 5, 2013). Controlled airspace would be established within a 4.3-mile radius of Tri-Cities Airport, with a segment extending from the 4.3-mile radius of the airport to 6.8 miles northeast of the airport. This action is necessary for continued safety and management of IFR operations in the Tri-Cities area.

Class D and E airspace designations are published in Paragraphs 5000, 6002, and 6004, respectively of FAA Order 7400.9X, dated August 7, 2013, and effective September 15, 2013, 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 FAA has determined that this proposed 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 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.

The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. Subtitle I, 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 proposed 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 proposed regulation is within the scope of that authority as it would amend Class D and Class E airspace at Tri-Cities Regional Airport, Tri-Cities, TN.

This proposal would 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. Lists of Subjects in 14 CFR Part 71:

Airspace, Incorporation by reference, Navigation (air). The Proposed Amendment:

In consideration of the foregoing, the Federal Aviation Administration proposes to amend 14 CFR part 71 as follows:

The FAA is considering an amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 to amend Class E airspace extending upward from 700 feet above the surface at Greenville Municipal Airport, Greenville, ME. Airspace reconfiguration to within a 9.4- mile radius of the airport is necessary due to the decommissioning of the Squaw NDB and cancellation of the NDB approach, and for continued safety and management of IFR operations at the airport. The geographic coordinates of Greenville Municipal Airport would be adjusted to coincide with the FAA’s aeronautical database.

Class E airspace designations are published in Paragraph 6005 of FAA Order 7400.9X, dated August 7, 2013, and effective September 15, 2013, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designation
