Discussion The NRC is requesting comments on a draft regulatory basis to support a proposed rulemaking on financial qualifications for reactor licensing. The regulatory basis explains, in part, why the existing regulations should be updated. It also discusses cost and other impacts of the potential changes. The specific objective of this proposed rulemaking would be to amend the current financial qualification requirements of ‘‘reasonable assurance’’ under 10 CFR part 50 to conform to the 10 CFR part 70 review standard of ‘‘appears to be financially qualified.’’ Specifically, the proposed rulemaking will remove the detailed requirements found in Appendix C of 10 CFR Part 50 and amend 10 CFR 50.33(f) to remove the requirement for a power reactor applicant to demonstrate that it possesses or can provide reasonable assurance of obtaining the funds necessary for construction and operation. In this proposed rulemaking, the applicant would be required to submit a plan describing how it will proceed to finance the construction and operation of the facility. The plan would ensure that the applicant has both a well-articulated understanding of the size of the project it is undertaking and the financial capacity to obtain the necessary financing before beginning reactor construction. The proposed rulemaking would permit the NRC to issue licenses with conditions to applicants that may have insufficient (or no) funding at the outset of the license application review. The license conditions would be sufficient and specific to permit a simple, ministerial kind of review to ensure that VerDate Sep<11>2014 16:32 Jun 16, 2015 Jkt 235001 III. Specific Requests for Comments The NRC requests that stakeholders consider the questions in Enclosure 2 of the draft regulatory basis. The questions, identified during development of the draft regulatory basis, cover the scope, objectives, implementation, and cost of a proposed rulemaking based on this regulatory basis. 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 any regulatory analysis by the NRC. V. Public Meeting the applicant’s plan is executed before beginning reactor construction. IV. Cumulative Effects of Regulation The Cumulative Effects of Regulation (CER) describes 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. Therefore, the NRC is specifically requesting comment on the cumulative effects that may result from this proposed rulemaking. In developing comments on the draft regulatory basis, 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 NRC or other agencies influence the implementation of the potential proposed requirements? (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 PO 00000 Frm 00021 Fmt 4702 Sfmt 4702 A public meeting will be held on July 8, 2015, from 1:00 p.m.–4:00 p.m. at the NRC Headquarters, One White Flint North, 11555 Rockville Pike, Rockville, Maryland, Room O–4B6. The purpose of the public meeting is to promote full understanding of this regulatory basis for the proposed rulemaking and to facilitate public comment. The NRC will not be accepting verbal or written comments at the public meeting. All comments must be submitted as indicated in the ADDRESSES section of this document. Stakeholders should monitor the NRC’s public meeting Web site for information about the public meeting at http://www.nrc.gov/public-involve/ public-meetings/index.cfm. VI. 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 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 9th day of June, 2015.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We propose to adopt a new AD for all GE GEnx–1B turbofan engine models. This proposed AD was prompted by multiple reports of engine oil loss and resultant flight plan diversions. The root cause of the engine oil loss is a nonconforming ball valve in the secondary seal of the oil filler cap. The nonconforming ball valve may prevent correct sealing and lead to oil leakage. This proposed AD would require removal and replacement of the nonconforming ball valve in the oil filler cap. This condition, if not corrected, could result in loss of engine oil, which could lead to failure of one or more engines, loss of thrust control, and damage to the airplane. Related Service Information We reviewed GE GEnx–1B Service Bulletin (SB) No. 79–0022, Revision 1, dated May 13, 2015. The SB describes procedures for removing and replacing the ball valve in the oil filler cap. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require removal and replacement of the non- PO 00000 Frm 00022 Fmt 4702 Sfmt 4702 34561 conforming ball valve in the oil filler cap. Costs of Compliance We estimate that this proposed AD will affect 86 engines installed on airplanes of U.S. registry. We also estimate that it will take about 1 hour per engine to comply with this proposed AD. The average labor rate is $85 per hour. We estimate that replacement parts would cost $11 per engine. Based on these figures, we estimate the total cost of the proposed AD to U.S. operators to be $8,256. 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 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.

Discussion

    We propose to adopt a new AD for all GE GEnx-1B turbofan engine 
models. This proposed AD was prompted by multiple reports of engine oil 
loss and resultant flight plan diversions. The root cause of the engine 
oil loss is a non-conforming ball valve in the secondary seal of the 
oil filler cap. The non-conforming ball valve may prevent correct 
sealing and lead to oil leakage. This proposed AD would require removal 
and replacement of the non-conforming ball valve in the oil filler cap. 
This condition, if not corrected, could result in loss of engine oil, 
which could lead to failure of one or more engines, loss of thrust 
control, and damage to the airplane.

Related Service Information

    We reviewed GE GEnx-1B Service Bulletin (SB) No. 79-0022, Revision 
1, dated May 13, 2015. The SB describes procedures for removing and 
replacing the ball valve in the oil filler cap.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require removal and replacement of the non-
conforming ball valve in the oil filler cap.

Costs of Compliance

    We estimate that this proposed AD will affect 86 engines installed 
on airplanes of U.S. registry. We also estimate that it will take about 
1 hour per engine to comply with this proposed AD. The average labor 
rate is $85 per hour. We estimate that replacement parts would cost $11 
per engine. Based on these figures, we estimate the total cost of the 
proposed AD to U.S. operators to be $8,256.

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 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 to the extent 
that it justifies making a regulatory distinction, 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.
