Rulemaking Distribution System, which describes the application procedure. The Proposal

The FAA is proposing an amendment to Title 14 Code of Federal Regulations (14 CFR) part 71 to modify the Norton Sound Low, Control 1234L, and Control 1487L Offshore Airspace Areas in Alaska. The Norton Sound Low Offshore Airspace Area would be modified by lowering the offshore airspace floor to 1,200 feet mean sea level (MSL) within a 73-mile radius of Port Clarence CGS Airport, excluding that airspace west of a line extending from lat. 64 ° 48 ′ 20′′ N., long. 169 ° 31 ′ 27 ′′ W., to lat. 65 ° 00 ′00′′ N., long. 168 ° 58 ′ 23 ′′ W., to lat. 66 ° 05 ′44 ′′ N., long. 168 ° 58 ′ 23 ′′ W.; and within 73 miles of the Savoonga Airport excluding that airspace west of a line from lat. 68 ° 00 ′00 ′′ N., long.
168 ° 58 ′ 23 ′′ W., to lat. 65 ° 00 ′00 ′′ N., long.
168 ° 58 ′ 23 ′′ W., to lat. 62 ° 35 ′00 ′′ N., long.
175 ° 00 ′00′′ W.; and within 73 miles of Platinum Airport excluding that airspace west of a line from lat.
59 ° 59 ′ 57 ′′ N., long. 168 ° 00 ′08 ′′ W., to lat.
57 ° 45 ′ 57 ′′ N., long. 161 ° 46 ′08 ′′ W.

The Offshore Airspace Area Control 1234L would be modified by lowering the offshore airspace floor to 1,200 feet above the surface within a 10-mile radius of the Casco Cove CGS Airport. Additionally, Control 1234L would be further modified by lowering the offshore airspace floor to 700 feet above the surface within an 8-mile radius of St. Paul Island Airport, St. Paul Island, AK.

Control 1487L would be modified by lowering the offshore airspace floor to 1,200 feet above the surface within 75 miles of the Yakutat VOR/DME.

Offshore airspace areas are published in paragraph 2003 of FAA Order 7400.9U dated August 18, 2010 and effective September 15, 2010, which is incorporated by reference in 14 CFR 71.1. The offshore airspace areas 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. Therefore, this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under Department of Transportation (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, 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 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 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 modifies offshore airspace areas in Alaska.

Environmental Review

The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA Order 1050.1E, Environmental Impacts: Policies and Procedures, paragraph 311a. This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist that warrant preparation of an environmental assessment.

ICAO Considerations

As part of this proposal relates to navigable airspace outside the United States, this notice is submitted in accordance with the International Civil Aviation Organization (ICAO) International Standards and Recommended Practices.

The application of International Standards and Recommended Practices by the FAA, Office of Airspace Services, Airspace, Regulations and ATC Procedures Group, in areas outside the United States domestic airspace, is governed by the Convention on International Civil Aviation. Specifically, the FAA is governed by Article 12 and Annex 11, which pertain to the establishment of necessary air navigational facilities and services to promote the safe, orderly, and expeditious flow of civil air traffic. The purpose of Article 12 and Annex 11 is to ensure that civil aircraft operations on international air routes are performed under uniform conditions.

The International Standards and Recommended Practices in Annex 11 apply to airspace under the jurisdiction of a contracting state, derived from ICAO. Annex 11 provisions apply when air traffic services are provided and a contracting state accepts the responsibility of providing air traffic services over high seas or in airspace of undetermined sovereignty. A contracting state accepting this responsibility may apply the International Standards and Recommended Practices that are consistent with standards and practices utilized in its domestic jurisdiction.

In accordance with Article 3 of the Convention, state-owned aircraft are exempt from the Standards and Recommended Practices of Annex 11. The United States is a contracting state to the Convention. Article 3(d) of the Convention provides that participating state aircraft will be operated in international airspace with due regard for the safety of civil aircraft. Since this action involves, in part, the designation of navigable airspace outside the United States, the Administrator is consulting with the Secretary of State and the Secretary of Defense in accordance with the provisions of Executive Order
10854. List 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:

**PART 71—DESIGNATION OF CLASS A, B, C, D AND E AIRSPACE AREAS; AIR**  **TRAFFIC SERVICE ROUTES; AND REPORTING POINTS** 

1. The authority citation for part 71 continues to read as follows:

**§ 71.1 [Amended]**



### 2. The incorporation by reference in 14 CFR 71.1 of FAA Order 7400.9U, Airspace Designations and Reporting Points, dated August 18, 2010, and effective September 15, 2010, is amended as follows:
