You may review the public docket containing the proposal, any comments received and any final disposition in person in the Dockets Office (see

**ADDRESSES** section for address and phone number) between 9 a.m. and 5:00 p.m., Monday through Friday, except Federal holidays. An informal docket may also be examined during normal business hours at the office of the Central Service Center, 2601 Meacham Blvd., Fort Worth, TX 76137.

Persons interested in being placed on a mailing list for future NPRMs 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

This action proposes to amend Title 14, Code of Federal Regulations (14 CFR), Part 71 by amending Class E airspace designated as an extension to Class D at Sault Ste Marie Airport, Sault Ste Marie, ON, to coincide with that portion of the control zone in Canadian airspace. Controlled airspace is needed for the safety and management of IFR operations at the airport.

Class E airspace areas are published in Paragraph 6004 of FAA Order 7400.9V, dated August 9, 2011 and effective September 15, 2011, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designation listed in this document would 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 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 would amend controlled airspace at Sault Ste Marie Airport, Sault Ste Marie, ON.

Environmental Review

This proposal will 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. 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**

**§ 71.1 [Amended]**

2. The incorporation by reference in 14 CFR 71.1 of FAA Order 7400.9V, Airspace Designations and Reporting Points, dated August 9, 2011, and effective September 15, 2011, is amended as follows:

**Approval and Promulgation of Implementation Plans; California;**  **Determinations of Attainment for the 1997 8-Hour Ozone Standard** 

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  EPA is proposing determinations relating to 1997 8-hour ozone nonattainment areas in California. First, EPA is proposing to determine that six 8-hour ozone nonattainment areas in California (Amador and Calaveras Counties, Chico, Kern County, Mariposa and Tuolumne Counties, Nevada County, and Sutter County) (‘‘six CA areas’’) attained the 1997 8- hour ozone national ambient air quality standard (NAAQS) by their applicable attainment dates. Second, in making these proposed determinations for Mariposa and Tuolumne Counties and Nevada County, EPA is also proposing to grant them one-year attainment date extensions. Lastly, EPA is proposing to determine that the six CA areas and the Ventura County 8-hour ozone nonattainment area in CA have attained and continue to attain the 1997 8-hour ozone NAAQS based on the most recent three years of data. Under the provisions of EPA’s ozone implementation rule, these proposed determinations suspend the requirements for these areas to submit revisions to the state implementation plan related to attainment of the 1997 8-hour ozone standard for as long as these areas continue to meet the 1997 8-hour ozone NAAQS.
