Low-Level Radioactive Waste Disposal 

AGENCY: Nuclear Regulatory 

Commission. 

ACTION: Proposed rule and draft NUREG; 

reopening of comment period. 

SUMMARY: On March 26, 2015, the U.S. 

Nuclear Regulatory Commission (NRC) 

requested public comment on a 

proposed rule that would amend its 

regulations that govern low-level 

radioactive waste (LLRW) disposal 

facilities. The proposed rule would 

require new and revised site-specific 

technical analyses, permit the 

development of site-specific criteria for 

LLRW acceptance based on the results 

of those analyses, facilitate 

implementation, and better align the 

requirements with current health and 

safety standards. Also on March 26, 

2015, the NRC requested comment on 

draft guidance to address the 

implementation of the proposed 

regulations (NUREG–2175, ‘‘Guidance 

for Conducting Technical Analyses for 

10 CFR part 61’’). The public comment 

period for the proposed rule and draft 

guidance closed on July 24, 2015. The 

NRC is reopening the public comment 

periods for the proposed rule and draft 

guidance to allow more time for 

members of the public to develop and 

submit their comments. 

DATES: The comment periods for the 

proposed rule published on March 26, 

2015 (80 FR 16081), and the draft 

guidance published on March 26, 2015 

(80 FR 15930), have been reopened. 

Comments should be filed no later than 

September 21, 2015. 

ADDRESSES: The methods for submitting 

comments on the proposed rule are

On March 26, 2015 (80 FR 16081), the 

NRC requested comment on a proposed 

rule that would amend its regulations 

that govern LLRW disposal facilities to 

require new and revised site-specific 

technical analyses, to permit the 

development of site-specific criteria for 

LLRW acceptance based on the results 

of those analyses, to facilitate 

implementation, and to better align the 

requirements with current health and 

safety standards. Also on March 26, 

2015 (80 FR 15930), the NRC requested 

comments on draft guidance to address 

the implementation of the proposed 

regulations (NUREG–2175, ‘‘Guidance 

for Conducting Technical Analyses for 


rmajette on DSK2VPTVN1PROD with PROPOSALS
Federal Register / Vol. 80, No. 166 / Thursday, August 27, 2015 / Proposed Rules 51965 

10 CFR part 61’’). The public comment 

periods for the proposed rule and draft 

guidance closed on July 24, 2015. The 

NRC has decided to reopen the public

Airworthiness Directives; General 

Electric Company Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

General Electric Company (GE) GEnx– 

1B54, –1B58, –1B64, –1B67, and –1B70 

turbofan engine models. This proposed 

AD was prompted by reports of two inflight shutdowns (IFSDs) caused by 

high-pressure turbine (HPT) rotor stage 

1 blade failure. This proposed AD 

would require inspection and 

conditional removal of affected HPT 

rotor stage 1 blades. We are proposing 

this AD to prevent failure of the HPT 

rotor stage 1 blades, which could lead 

to failure of one or more engines, loss 

of thrust control, and damage to the 

airplane. 

DATES: We must receive comments on 

this proposed AD by October 26, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments. 

• Fax: 202–493–2251.

Transportation, Docket Operations, M–

• Hand Delivery: Deliver to Mail 

address above between 9 a.m. and 5 

p.m., Monday through Friday, except 

Federal holidays.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this NPRM. Send your comments to an 

address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2015–2984; Directorate Identifier 2015– 

NE–21–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this NPRM. We will consider 

all comments received by the closing 

date and may amend this NPRM 

because of those comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this NPRM. 

Discussion 

We propose to adopt a new AD for all 

GE GEnx–1B54, –1B58, –1B64, –1B67, 

and –1B70 turbofan engine models. This 

proposed AD was prompted by reports 

of two IFSDs caused by HPT rotor stage 

1 blade failure. This proposed AD 

would require inspection and 

conditional removal of affected HPT 

rotor stage 1 blades. This condition, if 

not corrected, could result in failure of 

the HPT rotor stage 1 blades, 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. 72–0267 R00, dated 

April 10, 2015. The SB describes 

procedures for borescope inspection 

(BSI) of the HPT rotor stage 1 blades. 

FAA’s Determination 

We are proposing this NPRM 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 NPRM would require initial and 

repetitive BSI and conditional removal 

of affected HPT rotor stage 1 blades. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 4 engines installed on 

airplanes of U.S. registry. We also 

estimate that it will take about 2 hours 

per engine to comply with this proposed 

AD. The average labor rate is $85 per 

hour. Based on these figures, we 

estimate the total cost of this proposed 

AD to U.S. operators to be $680. 

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
