March 13, 2017 – Federal Register Recent Federal Regulation Documents

This action proposes to establish Class E en route airspace extending upward from 1,200 feet above the surface to accommodate Instrument Flight Rules (IFR) aircraft under control of the Oakland Air Route Traffic Control Center (ARTCC), centered near Sacramento, CA. Establishment of this airspace area would ensure controlled airspace exists in those areas where the Federal airway structure is inadequate.

The Environmental Protection Agency (EPA) is determining that the Imperial County, California Moderate nonattainment area (``the Imperial County NA'') has attained the 2006 24-hour fine particulate matter (PM2.5) national ambient air quality standard (NAAQS or ``standard''). This determination, also known as a clean data determination (CDD), is based upon complete, quality-assured, and certified ambient air monitoring data showing that the area has monitored attainment of the 2006 24-hour PM2.5 NAAQS based on the 2013-2015 data available in the EPA's Air Quality System database. As a consequence of this determination of attainment, certain Clean Air Act (CAA) requirements that apply to the Imperial County Air Pollution Control District (ICAPCD or ``District'') shall be suspended for so long as the area continues to meet the 2006 24-hour PM2.5 NAAQS. The area remains nonattainment for the 2012 annual PM2.5 NAAQS. The EPA is also approving a revision to California's state implementation plan (SIP) consisting of the 2008 emissions inventory for the Imperial County NA submitted by the California Air Resources Board (CARB or ``State'') on January 9, 2015. This action is being taken under the CAA. Elsewhere in this issue of the Federal Register, we are proposing approval and soliciting written comment on these actions. If we receive adverse comments on this direct final rule that result in withdrawal of the entire rule or any part(s) of it, we will address those comments when we finalize the proposal. The EPA does not plan to institute a second comment period on this action. Any parties interested in commenting must do so at this time.

Pursuant to section (102)(2)(c) of the National Environmental Policy Act (NEPA) of 1969, and the regulations implemented by the Council on Environmental Quality (40 Code of Federal Regulations (CFR) parts 1500-1508), the Department of the Navy (DoN) announces its intent to prepare a Supplemental Environmental Impact Statement (EIS) to the July 2016 Final EIS for Land-Water Interface (LWI) and Service Pier Extension (SPE), Naval Base (NAVBASE) Kitsap Bangor, Washington. The Final EIS for LWI and SPE resulted in a Record of Decision (ROD) that was signed on September 8, 2016 for the LWI project only. The SPE proposed action is to extend the existing Service Pier and construct associated support facilities. The purpose is to provide additional berthing capacity and improve associated support facilities for existing homeported and visiting submarines at NAVBASE Kitsap Bangor. The SPE project is needed to provide alternative opportunities for berthing to mitigate restrictions at NAVBASE Kitsap Bremerton, Washington, on navigating SEAWOLF Class submarines through Rich Passage under certain tidal conditions and to improve long-term operational effectiveness for the three SEAWOLF Class submarines on NAVBASE Kitsap. The Supplemental EIS will address the SPE project only and will evaluate resources based upon changes in design and new information relevant to environmental concerns per 40 CFR 1502.9. The DoN will evaluate this new, relevant information and incorporate that information into revised analyses where appropriate. The analysis will address, among others, changes to the Alternative 2 design and new regulatory guidance and requirements.

We are superseding Airworthiness Directive (AD) 2015-16-02 for all Airbus Model A330 series airplanes. AD 2015-16-02 required revising the maintenance or inspection program to incorporate certain maintenance requirements and airworthiness limitations. This new AD requires revising the maintenance or inspection program to incorporate new maintenance requirements and airworthiness limitations. This AD was prompted by a revision of the airworthiness limitations items (ALI) document, which provides new and more restrictive maintenance requirements and airworthiness limitations for airplane structures and systems. We are issuing this AD to address the unsafe condition on these products.

We propose to supersede Airworthiness Directive (AD) 2014-08- 02 for certain Airbus Model A300 B4-600 and A300 B4-600R series airplanes. AD 2014-08-02 requires modifying the profile of stringer run-outs of both wings, including a high frequency eddy current (HFEC) inspection of the fastener holes for defects, and repairs if necessary. Since we issued AD 2014-08-02, further analysis in the context of widespread fatigue damage (WFD) concluded that a shorter compliance time is necessary to meet specified requirements to address WFD. This proposed AD would retain the actions required by AD 2014-08-02 and would revise the compliance times. We are proposing this AD to address the unsafe condition on these products.
