          - [Docket No. FAA-2008-1259; Airspace Docket No. 08-ASO-1]

# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Final rule.

# SUMMARY:

This action will amend the boundaries of the Atlantic High and San Juan Low Offshore Airspace Areas located off the east coast of the United States. The implementation of the West Atlantic Route System Plus (WATRS Plus) project modified the boundaries of the Miami Control Area (CTA)/Flight Identification Region (FIR), the San Juan CTA/FIR, and the New York Oceanic CTA/FIR. This action modifies the Atlantic High and San Juan Low Offshore Airspace Area boundaries to coincide with the CTA/FIR changes.

# DATES:

*Effective Date:*                         0901 UTC, July 2, 2009. The Director of the Federal Register approves this incorporation by reference action under 1 CFR part 51, subject to the annual revision of FAA Order 7400.9 and publication of conforming amendments.

# SUPPLEMENTARY INFORMATION:

## History

                    On Thursday January 15, 2009, the FAA published in the                     **Federal Register**                     a notice of proposed rulemaking to modify the Atlantic High and San Juan Low Offshore Airspace Areas, East Coast, United States (74 FR 2427). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal. No comments were received. With the exception of editorial changes, this amendment is the same as that proposed in the NPRM.                

                    High offshore airspace areas are published in paragraph 2003, and low offshore airspace areas are published in paragraph 6007, of FAA Order 7400.9S signed October 3, 2008, and effective October 31, 2008, which is incorporated by reference in 14 CFR 71.1. The offshore airspace areas listed in this                           ( print page 18289)                        document will be published subsequently in the Order.                

## The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by modifying the boundaries of the Atlantic High and San Juan Low Offshore Airspace Areas to match recent boundary changes to the Miami, San Juan and New York Oceanic CTA/FIRs. The CTA/FIR boundaries were modified due to the implementation of the WATRS Plus project, which introduced a redesigned route structure and a reduced lateral separation standard on oceanic routes in the WATRS Plus CTAs to enhance en route capacity. This change is a minor realignment of one point common to both the Atlantic High and San Juan Low Offshore Airspace area boundaries. The point at lat. 21°08′00′ N., long. 67°45′00″ W. is changed to read lat. 21°14′21″ N., long. 67°39′02″ W.

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 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 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 Administration. 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 enhances the safety of aircraft within the National Airspace System.

## ICAO Considerations

As this action 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 System Operations Airspace and AIM, Airspace & Rules, 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 the designation of navigable airspace outside the United States, the Administrator consulted with the Secretary of State and the Secretary of Defense in accordance with the provisions of Executive Order 10854.

## Environmental Review

The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with paragraph 311a of FAA Order 1050.1E, Environmental Impacts: Polices and Procedures. 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.
