Download as PDF nlaroche on DSK30NT082PROD with PROPOSALS 21482 Federal Register / Vol. 82, No. 88 / Tuesday, May 9, 2017 / Proposed Rules recommending rulemaking to: (1) Require that the post-shutdown decommissioning activities report (PSDAR) contain a description of how the spent fuel stored under a general independent spent fuel storage installation license will be removed from the reactor site in accordance with the regulatory requirements in § 50.82, ‘‘Termination of License,’’ of title 10 of the Code of Federal Regulations (10 CFR), 10 CFR 50.54(bb), 10 CFR 52.110, ‘‘Termination of License,’’ and 10 CFR 72.218, ‘‘Termination of Licenses;’’ and (2) amend 10 CFR 51.53, ‘‘Postconstruction Environmental Reports,’’ and 10 CFR 51.95, ‘‘Postconstruction Environmental Impact Statements,’’ to clarify that the requirements for a license amendment before decommissioning activities may commence applies only to non-power reactors, as specified in 10 CFR 50.82(b). In the draft regulatory basis, the NRC concludes that regulatory activities other than rulemaking—such as guidance development—should be used to address stakeholder concerns regarding the appropriate role of State and local governments in the decommissioning process, the level of NRC review and approval of the PSDAR, and the 60 year limit for power reactor decommissioning. The NRC also determined that additional stakeholder input is needed prior to finalizing recommendations related to cyber security, drug and alcohol testing, certified fuel handler training and minimum staffing, aging management, and fatigue management. The NRC is seeking specific public input on these topics as part of the public comment request on the entire draft regulatory basis. To supplement the draft regulatory basis, the NRC has prepared a preliminary draft regulatory analysis, in which the costs, benefits, and other impacts of each rulemaking alternative are presented in order to determine the economic impact to industry and to government from the proposed rulemaking. The NRC prepared the preliminary draft regulatory analysis to support decision making during the preparation of the draft regulatory basis document, which includes an evaluation of possible regulatory improvements for reactors transitioning to decommissioning. III. Request for Comment The NRC is requesting comment on the preliminary draft regulatory analysis that was prepared to support the draft regulatory basis for the ‘‘Regulatory Improvements for Reactors Transitioning to Decommissioning’’ VerDate Sep<11>2014 13:36 May 08, 2017 Jkt 241001 rulemaking. As you prepare your comments, consider the following general questions: 1. Is the NRC considering appropriate alternatives for each regulatory area described in the preliminary draft regulatory analysis? 2. Are there additional factors that the NRC should consider in each regulatory area? What are these factors? 3. Is there additional information concerning regulatory impacts that the NRC should include in its regulatory analysis for this rulemaking? 4. Are all costs and benefits properly addressed to determine the economic impact of the rulemaking alternatives? 5. What additional costs or cost savings will the rulemaking alternatives cause to society, industry, and government? IV. Cumulative Effects of Regulation The cumulative effects of regulation (CER) describe the challenges that licensees or other impacted entities (such as State agency partners) may face while implementing new regulatory positions, programs, and requirements (e.g., rules, generic letters, backfits, inspections). The CER is an organizational effectiveness challenge that results from a licensee or impacted entity implementing a number of complex positions, programs, or requirements within a limited implementation period and with available resources (which may include limited available expertise to address a specific issue). The NRC has implemented CER enhancements to the rulemaking process to facilitate public involvement throughout the rulemaking process. In developing comments on the preliminary draft regulatory analysis, consider the following questions: (1) In light of any current or projected CER challenges, what should be a reasonable effective date, compliance date, or submittal date(s) from the time the final rule is published to the actual implementation of any new proposed requirements, including changes to programs, procedures, or the facility? (2) If current or projected CER challenges exist, what should be done to address this situation (e.g., if more time is required to implement the new requirements, what period of time would be sufficient, and why such a time frame is necessary)? (3) Do other regulatory actions (e.g., orders, generic communications, license amendment requests, and inspection findings of a generic nature) by the NRC or other agencies influence the implementation of the potential proposed requirements? PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 (4) Are there unintended consequences? Does the potential proposed action create conditions that would be contrary to the potential proposed action’s purpose and objectives? If so, what are the consequences and how should they be addressed? (5) Please provide information on the costs and benefits of the potential proposed action. This information will be used to support additional regulatory analysis by the NRC. V. Plain Writing The Plain Writing Act of 2010 (Pub. L. 111–274) requires Federal agencies to write documents in a clear, concise, well-organized manner. The NRC has written this document to be consistent with the Plain Writing Act as well as the Presidential Memorandum, ‘‘Plain Language in Government Writing,’’ published in the Federal Register on June 10, 1998 (63 FR 31883). The NRC requests comment on this document with respect to the clarity and effectiveness of the language used. Dated at Rockville, Maryland, this 3rd day of May 2017.

Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2016–33, dated October 12, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model CL–215–6B11 (CL–415 Variant) airplanes. The MCAI states: During the implementation of Service Bulletin (SB) 215–4051, the oxygen bottle was found loose while the clamp strap was in the locked position. This was determined to be caused by the quick release latch assembly not achieving the proper clamping pressure. The release of the oxygen bottle due to improper clamping pressure may result in a loose mass cockpit hazard or an oxygen rich environment leading to a possible fire hazard. In order to mitigate the unsafe condition, SB 215–4457 was issued to modify the clamp strap and install additional shims to add strength to the attaching structure for all affected aeroplanes. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2017– 0333. Related Service Information Under 1 CFR Part 51 We reviewed Bombardier Service Bulletin 215–4457, Revision 3, dated May 8, 2013. The service information describes procedures for installing shims, and, for certain airplanes, modifying the straps of the latch assembly, on the flight crew’s oxygen bottles’ retaining structure. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance We estimate that this proposed AD affects 26 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action nlaroche on DSK30NT082PROD with PROPOSALS Modification and installation Labor cost 16 work-hours × $85 per hour = $1,360 ................................ Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety.

This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify this proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 3. Will not affect intrastate aviation in Alaska; and 4.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2016-33, dated October 
12, 2016 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Bombardier, Inc., Model CL-215-6B11 (CL-415 
Variant) airplanes. The MCAI states:

    During the implementation of Service Bulletin (SB) 215-4051, the 
oxygen bottle was found loose while the clamp strap was in the 
locked position. This was determined to be caused by the quick 
release latch assembly not achieving the proper clamping pressure.
    The release of the oxygen bottle due to improper clamping 
pressure may result in a loose mass cockpit hazard or an oxygen rich 
environment leading to a possible fire hazard.
    In order to mitigate the unsafe condition, SB 215-4457 was 
issued to modify the clamp strap and install additional shims to add 
strength to the attaching structure for all affected aeroplanes.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0333.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Service Bulletin 215-4457, Revision 3, dated 
May 8, 2013. The service information describes procedures for 
installing shims, and, for certain airplanes, modifying the straps of 
the latch assembly, on the flight crew's oxygen bottles' retaining 
structure. This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 26 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                      hour = $1,360.
----------------------------------------------------------------------------------------------------------------

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for

[[Page 21484]]

safety in air commerce. This regulation is within the scope of that 
authority because it addresses an unsafe condition that is likely to 
exist or develop on products identified in this rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

    Authority:  49 U.S.C. 106(g), 40113, 44701.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Bombardier, Inc. (Type Certificate Previously Held by Canadair 
Limited): Docket No. FAA-2017-0333; Directorate Identifier 2017-NM-
005-AD.

(a) Comments Due Date

    We must receive comments by June 23, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc. (Type Certificate previously 
held by Canadair Limited) Model CL-215-6B11 (CL-415 Variant) 
airplanes, certificated in any category, having serial numbers 2001, 
2002, 2005 through 2007 inclusive, 2010, 2012 through 2017 
inclusive, 2019, 2022 through 2024 inclusive, 2026, 2057, 2063, 
2065, 2076, 2077, and 2081.

(d) Subject

    Air Transport Association (ATA) of America Code 25, Equipment/
Furnishings.

(e) Reason

    This AD was prompted by a report indicating that an oxygen 
bottle was found loose while the clamp strap was in the locked 
position. We are issuing this AD to prevent an oxygen bottle from 
being released, which would result in a loose mass object in the 
cockpit and could also result in an oxygen-rich environment that 
could lead to a possible fire hazard.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Installation and Modification

    Within 12 months after the effective date of this AD, install 
additional shims and modify the clamp strap, as applicable, to the 
flight crew's oxygen bottle retaining structures, in accordance with 
the Accomplishment Instructions of Bombardier Service Bulletin 215-
4457, Revision 3, dated May 8, 2013.

(h) Credit for Previous Actions

    This paragraph provides credit for actions required by paragraph 
(g) of this AD, if those actions were performed before the effective 
date of this AD using any of the service information identified in 
paragraphs (h)(1), (h)(2), or (h)(3) of this AD.
    (1) Bombardier Service Bulletin 215-4457, Revision 2, dated
