Discussion On March 24, 2014, the NRC published a proposed rule revising the acceptance criteria for the ECCS for light-water nuclear power reactors (79 FR 16106). The proposed ECCS acceptance criteria are performancebased, and reflect recent research findings that identified new embrittlement mechanisms for fuel rods with zirconium alloy cladding under loss-of-coolant accident conditions. The proposed rule also addresses two petitions for rulemaking by establishing requirements applicable to all fuel types and cladding materials, and requiring the consideration of crud, oxide deposits, and hydrogen content in zirconium-based alloy fuel cladding. Further, the proposed rule contains a provision that would allow licensees to use an alternative risk-informed approach to evaluate the effects of debris for long-term cooling. The NRC is also seeking public comment on three draft regulatory guides that would support the implementation of the proposed rule. The public comment period for the proposed rule and associated draft guidance was to have ended on June 9, 2014.

The Proposal This action proposes to amend Title 14, Code of Federal Regulations (14 CFR), Part 71 by establishing Class E airspace extending upward from 700 feet above the surface within a 7-mile radius of Steele Municipal Airport, Steele, MO, to accommodate new standard instrument approach procedures. Controlled airspace is needed for the safety and management of IFR operations at the airport. Class E airspace areas 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 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 E:\FR\FM\22APP1.SGM 22APP1
