procedures at the airport. This improves the safety and management of Instrument Flight Rules (IFR) operations at the airport. Also, the geographic coordinates of the airport are updated at the request of National Aeronautical Navigation Services.

**DATES :**  Effective date, 0901 UTC, March 7, 2013. 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 September 11, 2012, the FAA published in the Federal Register a notice of proposed rulemaking (NPRM) to establish controlled airspace at Spanish Peaks Airfield, Walsenburg, CO (77 FR 55776). 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 E airspace designations are published in paragraph 6005, of FAA Order 7400.9W dated August 8, 2012, and effective September 15, 2012, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in that Order.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) Part 71 by establishing Class E airspace extending upward from 700 and 1,200 feet above the surface, at Spanish Peaks Airfield, Walsenburg, CO, to accommodate IFR aircraft executing new RNAV (GPS) standard instrument approach procedures at the airport. Also, the geographic coordinates of the airport are updated to coincide with the FAA’s aeronautical database. This action is necessary for the safety and management of IFR operations.

The FAA has determined 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 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 discusses 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 Spanish Peaks Airfield, Walsenburg, CO.

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.

**Amendment of Time of Designation for Restricted Area R–6501B; Underhill, VT** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule.

**SUMMARY :**  This action amends the time of designation for restricted area R– 6501B, Underhill, VT by adding a requirement for issuance of a Notice to Airmen (NOTAM) 24 hours in advance of any activation of the restricted area. This action does not affect the boundaries, altitudes or activities conducted within the area.

**DATES :**  Effective date 0901 UTC, January 10, 2013.

**SUPPLEMENTARY INFORMATION :**  Background

The current time of designation of restricted area R–6501B reads


### 75838 Federal Register / Vol. 77, No. 247 / Wednesday, December 26, 2012 / Rules and Regulations

‘‘Intermittent.’’ The term ‘‘intermittent’’ signifies limited or infrequent use the area. FAA Order 7400.2 requires that an ‘‘intermittent’’ time of designation for special use airspace areas must include either an associated time period or a ‘‘by NOTAM’’ provision. In all cases, an ‘intermittent’’ time of designation must not be used for restricted areas without a ‘‘by NOTAM’’ provision.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) part 73 by changing the time of designation for Restricted area R–6501B, Underhill, VT, from ‘‘Intermittent’’ to ‘‘Intermittent by NOTAM 24 hours in advance.’’ This change brings the time of designation into compliance with FAA Order 7400.2 requirements.

This change adds a NOTAM requirement to the time of designation of R–6501B. The change benefits the flying public by providing advance notice of planned activation periods of the restricted area. Because the amendment does not affect the boundaries, designated altitudes, or activities conducted within the restricted area and provides the public with advance notice of restricted area usage, notice and public procedures under 5 U.S.C. 553(b) are unnecessary.

The FAA has determined that this action 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.

Environmental Review

The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with 311d., FAA Order 1050.1E, Environmental Impacts: Policies and Procedures. This airspace action is an administrative change to the description of the affected restricted area to clarify the time of designation. It does not alter the dimensions, altitudes, or activities conducted within the airspace; therefore, it is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exists that warrant preparation of an environmental
assessment. List of Subjects in 14 CFR Part 73

**ACTION :**  Final rule.

**SUMMARY :**  Under section 215 of the Federal Power Act, the Federal Energy Regulatory Commission (Commission) approves regional Reliability Standard PRC–006–SERC–01 (Automatic Underfrequency Load Shedding Requirements), submitted to the Commission for approval by the North American Electric Reliability Corporation (NERC). Regional Reliability Standard PRC–006–SERC–01 is designed to ensure that automatic underfrequency load shedding protection schemes, designed by planning coordinators and implemented by applicable distribution providers and transmission owners in the SERC Reliability Corporation Region, are coordinated to mitigate the consequences of an underfrequency event effectively. The Commission approves the related violation risk factors, with one modification, violation severity levels, implementation plan, and effective date proposed by NERC.

Final Rule

Order No. 772

(Issued December 20, 2012)

1. Under section 215 of the Federal Power Act (FPA), the Commission approves regional Reliability Standard PRC–006–SERC–01 (Automatic Underfrequency Load Shedding Requirements) in the SERC Reliability Corporation (SERC) Region. The Commission also approves the related violation risk factors (VRF), with one modification, violation severity levels (VSL), implementation plan, and effective date proposed by the North American Electric Reliability Corporation (NERC). NERC submitted regional Reliability Standard PRC–006– SERC–01 to the Commission for approval and the new standard is designed to ensure that automatic underfrequency load shedding (UFLS) protection schemes, designed by planning coordinators and implemented by applicable distribution providers and transmission owners in the SERC Region, are coordinated to mitigate the consequences of an underfrequency event effectively.
