Professional services means the 

provision of personal services by an 

employee, including the rendering of 

advice or consultation, which involves 

application of the skills of a profession 

as defined in 5 CFR 2636.305(b)(1) or 

involves a fiduciary relationship as 

defined in 5 CFR 2636.305(b)(2). 

Note to § 7401.102(b): There is a special 

approval requirement set out in both 18 

U.S.C. 203(d) and 205(e), respectively, for 

certain representational activities otherwise 

covered by the conflict of interest restrictions 

on compensation and activities of employees 

in claims against and other matters affecting 

the Government. Thus, an employee who 

wishes to act as agent or attorney for, or 

otherwise represent his parents, spouse, 

child, or any person for whom, or any estate 

for which, he is serving as guardian, 

executor, administrator, trustee, or other 

personal fiduciary in such matters must 

obtain the approval required by law of the 

Government official responsible for the 

employee’s appointment in addition to the 

regulatory approval required in this section. 

(c) Procedure for requesting approval. 

(1) The approval required by paragraph 

(a) of this section shall be requested by 

e-mail or other form of written 

correspondence in advance of engaging 

in outside employment as defined in 

paragraph (b) of this section. 

(2) The request for approval to engage 

in outside employment or certain other 

activities shall set forth, at a minimum: 

(i) The name of the employer or 

organization; 

(ii) The nature of the legal activity or 

other work to be performed; 

(iii) The title of the position; and 

(iv) The estimated duration of the 

outside employment. 

(3) Upon a significant change in the 

nature or scope of the outside 

employment or in the employee’s 

official position within the MSPB, the 

employee must, within 7 calendar days 

of the change, submit a revised request 

for approval. 

(d) Standard for approval. Approval 

shall be granted only upon a 

determination that the outside 

employment is not expected to involve 

conduct prohibited by statute or Federal 

regulation, including 5 CFR part 2635. 

(e) DAEO’s and alternate DAEO’s 

responsibilities. The MSPB DAEO or 

alternate DAEO may issue instructions 

or manual issuances governing the 

submission of requests for approval of 

outside employment. The instructions 

or manual issuances may exempt 

categories of employment from the prior 

approval requirement of this section 

based on a determination that 

employment within those categories of 

employment would generally be 

approved and is not likely to involve 

conduct prohibited by statute or Federal 

regulation, including 5 CFR part 2635. 

The DAEO or alternate DAEO may 

include in these instructions or 

issuances examples of outside 

employment that are permissible or 

impermissible consistent with this part 

and 5 CFR part 2635.

NUCLEAR REGULATORY 

COMMISSION 

10 CFR Part 72 

RIN 3150–AI13 

List of Approved Spent Fuel Storage 

Casks: NAC–MPC Revision 5 

AGENCY: Nuclear Regulatory 

Commission. 

ACTION: Direct final rule. 

SUMMARY: The Nuclear Regulatory 

Commission (NRC) is amending its 

regulations revising the NAC 

International, Inc., NAC-Multi-Purpose 

Canister (MPC) system listing within the 

‘‘List of Approved Spent Fuel Storage 

Casks’’ to include Amendment No. 5 to 

Certificate of Compliance (CoC) Number 

1025. Amendment No. 5 will modify the 

CoC by revising the Technical 

Specifications (TS) to incorporate 

changes to the reporting and monitoring 

requirements to allow for visual 

inspection of the air inlet and outlet 

vents instead of thermal monitoring, 

revising the TS to incorporate guidance 

from NRC Interim Staff Guidance-22 

and replace all references to backfilling 

the cask with air to backfilling with 

inert gas, revising the CoC description to 

remove the requirement for tamperindicating devices on the Vertical 

Concrete Casks, and including several 

editorial changes to improve the clarity 

of the documents associated with the 

NAC–MPC system, under the general 

provisions that govern licensing 

requirements for the independent 

storage of spent nuclear fuel, high level 

radioactive waste, and reactor-related 

greater than Class C waste. 

DATES: The final rule is effective July 24, 

2007, unless significant adverse 

comments are received by June 11, 

2007. A significant adverse comment is 

a comment where the commenter 

explains why the rule would be 

inappropriate, including challenges to 

the rule’s underlying premise or 

approach, or would be ineffective or 

unacceptable without a change. If the 

rule is withdrawn, timely notice will be 

published in the Federal Register.

SUPPLEMENTARY INFORMATION: 

Background 

Section 218(a) of the Nuclear Waste 

Policy Act of 1982, as amended 

(NWPA), requires that ‘‘[t]he Secretary 

[of the Department of Energy (DOE)] 

shall establish a demonstration program, 

in cooperation with the private sector, 

for the dry storage of spent nuclear fuel 

at civilian nuclear power reactor sites, 

with the objective of establishing one or 

more technologies that the [Nuclear 

Regulatory] Commission may, by rule, 

approve for use at the sites of civilian 

nuclear power reactors without, to the 

maximum extent practicable, the need 

for additional site-specific approvals by 

the Commission.’’ Section 133 of the 

NWPA states, in part, that ‘‘[t]he 

Commission shall, by rule, establish 

procedures for the licensing of any 

technology approved by the 

Commission under Section 218(a) for 

use at the site of any civilian nuclear 

power reactor.’’

To implement this mandate, the NRC 

approved dry storage of spent nuclear 

fuel in NRC-approved casks under a 

general license by publishing a final 

rule in 10 CFR part 72 entitled, ‘‘General 

License for Storage of Spent Fuel at 

Power Reactor Sites’’ (55 FR 29181; July 

18, 1990). This rule also established a 

new Subpart L within 10 CFR part 72, 

entitled ‘‘Approval of Spent Fuel 

Storage Casks’’ containing procedures 

and criteria for obtaining NRC approval 

of spent fuel storage cask designs. The 

NRC subsequently issued a final rule on 

March 9, 2000 (65 FR 12444), that 

approved the NAC–MPC cask design 

and added it to the list of NRC-approved 

cask designs in 10 CFR 72.214 as CoC 

No. 1025. 

Discussion 

On July 17, 2006, and as 

supplemented on September 13, 2006, 

the certificate holder, NAC, submitted 

an application to the NRC requesting 

modifications to CoC No. 1025 by: (1) 

Revising the TS to incorporate changes 

to the reporting and monitoring 

requirements to allow for visual 

inspection of the air inlet and outlet 

vents instead of thermal monitoring; (2) 

revising the TS to incorporate guidance 

from NRC Interim Staff Guidance (ISG)–

22 and replace all references to 

backfilling the cask with air to 

backfilling with inert gas; and (3) 

revising the CoC description to remove 

the requirement for tamper-indicating 

devices on the Vertical Concrete Casks. 

Also, the amendment includes several 

editorial changes to improve the clarity 

of the documents associated with the 

NAC–MPC system. No other changes to 

the NAC–MPC cask design were 

requested in this application. The NRC 

staff performed a detailed safety 

evaluation of the proposed CoC 

amendment request and found that an 

acceptable safety margin is maintained. 

In addition, the NRC staff has 

determined that there continues to be 

reasonable assurance that public health 

and safety and the environment will be 

adequately protected. 

This direct final rule revises the 

NAC–MPC cask design listing in 10 CFR 

72.214 by adding Amendment No. 5 to 

CoC No. 1025. The amendment consists 

of changes to the CoC by revising the TS 

to incorporate changes to the reporting 

and monitoring requirements to allow 

for visual inspection of the air inlet and 

outlet vents instead of thermal 

monitoring, revising the TS to 

incorporate guidance from NRC ISG–22 

and replace all references to backfilling 

the cask with air to backfilling with 

inert gas, revising the CoC description to 

remove the requirement for tamperindicating devices on the Vertical 

Concrete Casks, and including several 

editorial changes to improve the clarity 

of the documents associated with the 

NAC–MPC system. The particular TS 

that are changed are identified in the 

NRC staff’s SER for Amendment No. 5. 

The amended NAC–MPC cask design, 

when used under the conditions 

specified in the CoC, the TS, and NRC 

regulations, will meet the requirements 

of Part 72; thus, adequate protection of 

public health and safety will continue to 

be ensured. 

Discussion of Amendments by Section 

Section 72.214 List of Approved Spent 

Fuel Storage Casks 

Certificate No. 1025 is revised by 

adding the effective date of Amendment 

No. 5. 

Procedural Background 

This rule is limited to the changes 

contained in Amendment 5 to CoC No. 

1025 and does not include other aspects 

of the NAC–MPC cask design. The NRC 

is using the ‘‘direct final rule 

procedure’’ to issue this amendment 

because it represents a limited and 

routine change to an existing CoC that 

is expected to be noncontroversial. 

Adequate protection of public health 

and safety continues to be ensured. The 

amendment to the rule will become 

effective on July 24, 2007. However, if 

the NRC receives significant adverse 

comments by June 11, 2007, then the 

NRC will publish a document that 

withdraws this action and will 

subsequently address the comments 

received in a final rule as a response to 

the companion proposed rule published 

elsewhere in this Federal Register. The 

NRC will not initiate a second comment 

period on this action. 

A significant adverse comment is a 

comment where the commenter 

explains why the rule would be 

inappropriate, including challenges to 

the rule’s underlying premise or 

approach, or would be ineffective or 

unacceptable without a change. For 

example, a substantive response is 

required when: 

(1) The comment opposes the rule and 

provides a reason sufficient to require a 

substantive response in a notice-andcomment process. For example, in a 

substantive response: 

(a) The comment causes the NRC staff 

to reevaluate (or reconsider) its position 

or conduct additional analysis; 

(b) The comment raises an issue 

serious enough to warrant a substantive 

response to clarify or complete the 

record; or 

(c) The comment raises a relevant 

issue that was not previously addressed 

or considered by the NRC staff. 

(2) The comment proposes a change 

or an addition to the rule, and it is 

apparent that the rule would be 

ineffective or unacceptable without 

incorporation of the change or addition. 

(3) The comment causes the NRC staff 

to make a change (other than editorial) 

to the rule, CoC, or TS.

Federal Register / Vol. 72, No. 90 / Thursday, May 10, 2007 / Rules and Regulations 26537 

Voluntary Consensus Standards 

The National Technology Transfer 

and Advancement Act of 1995 (Pub. L. 

104–113) requires that Federal agencies 

use technical standards that are 

developed or adopted by voluntary 

consensus standards bodies unless the 

use of such a standard is inconsistent 

with applicable law or otherwise 

impractical. In this direct final rule, the 

NRC will revise the NAC–MPC cask 

design listed in § 72.214 (List of NRCapproved spent fuel storage cask 

designs). This action does not constitute 

the establishment of a standard that 

contains generally applicable 

requirements. 

Agreement State Compatibility 

Under the ‘‘Policy Statement on 

Adequacy and Compatibility of 

Agreement State Programs’’ approved by 

the Commission on June 30, 1997, and 

published in the Federal Register on 

September 3, 1997 (62 FR 46517), this 

rule is classified as Compatibility 

Category ‘‘NRC.’’ Compatibility is not 

required for Category ‘‘NRC’’

regulations. The NRC program elements 

in this category are those that relate 

directly to areas of regulation reserved 

to the NRC by the Atomic Energy Act of 

1954, as amended (AEA), or the 

provisions of Title 10 of the Code of 

Federal Regulations. Although an 

Agreement State may not adopt program 

elements reserved to NRC, it may wish 

to inform its licensees of certain 

requirements via a mechanism that is 

consistent with the particular State’s 

administrative procedure laws but does 

not confer regulatory authority on the 

State. 

Plain Language 

The Presidential Memorandum, 

‘‘Plain Language in Government 

Writing,’’ published June 10, 1998 (63 

FR 31883), directed that the 

Government’s documents be in clear 

and accessible language. The NRC 

requests comments on this direct final 

rule specifically with respect to the 

clarity and effectiveness of the language 

used. Comments should be sent to the 

address listed under the heading 

ADDRESSES above. 

Finding of No Significant 

Environmental Impact: Availability 

Under the National Environmental 

Policy Act of 1969, as amended, and the 

NRC regulations in Subpart A of 10 CFR 

part 51, the NRC has determined that 

this rule, if adopted, would not be a 

major Federal action significantly 

affecting the quality of the human 

environment and, therefore, an 

environmental impact statement is not 

required. The NRC has prepared an 

environmental assessment and, on the 

basis of this environmental assessment, 

has made a finding of no significant 

impact. This rule will amend the CoC 

for the NAC–MPC cask design within 

the list of approved spent fuel storage 

casks that power reactor licensees can 

use to store spent fuel at reactor sites 

under a general license. The amendment 

will incorporate changes to the 

reporting and monitoring requirements 

to allow for visual inspection of the air 

inlet and outlet vents instead of thermal 

monitoring, incorporate guidance from 

NRC ISG–22 and replace all references 

to backfilling the cask with air to 

backfilling with inert gas, revise the CoC 

description to remove the requirement 

for tamper-indicating devices on the 

Vertical Concrete Casks, and make 

several editorial changes to improve the 

clarity of the documents associated with 

the NAC–MPC system. The 

environmental assessment and finding 

of no significant impact on which this 

determination is based are available for 

inspection at the NRC Public Document 

Room, 11555 Rockville Pike, Rockville, 

MD. Single copies of the environmental 

assessment and finding of no significant 

impact are available from Jayne M.

Paperwork Reduction Act Statement 

This direct final rule does not contain 

a new or amended information 

collection requirement subject to the 

Paperwork Reduction Act of 1995 (44 

U.S.C. 3501 et seq.). Existing 

requirements were approved by the 

Office of Management and Budget, 

Approval Number 3150–0132, 10 CFR 

Part 72. 

Public Protection Notification 

The NRC may not conduct or sponsor, 

and a person is not required to respond 

to, a request for information or an 

information collection requirement 

unless the requesting document 

displays a currently valid OMB control 

number. 

Regulatory Analysis 

On July 18, 1990 (55 FR 29181), the 

NRC issued an amendment to 10 CFR 

part 72 to provide for the storage of 

spent nuclear fuel under a general 

license in cask designs approved by the 

NRC. Any nuclear power reactor 

licensee can use NRC-approved cask 

designs to store spent nuclear fuel if it 

notifies the NRC in advance, spent fuel 

is stored under the conditions specified 

in the cask’s CoC, and the conditions of 

the general license are met. A list of 

NRC-approved cask designs is contained 

in 10 CFR 72.214. On March 9, 2000 (65 

FR 12444), the NRC issued an 

amendment to part 72 that approved the 

NAC–MPC cask design by adding it to 

the list of NRC-approved cask designs in 

10 CFR 72.214. On July 17, 2006, and 

as supplemented on September 13, 

2006, the certificate holder, NAC, 

submitted an application to the NRC to 

amend CoC No. 1025 to revise TS to 

incorporate changes to the reporting and 

monitoring requirements to allow for 

visual inspection of the air inlet and 

outlet vents instead of thermal 

monitoring under the general license 

provisions of 10 CFR part 72, 

incorporate guidance from NRC ISG–22 

and replace all references to backfilling 

the cask with air to backfilling with 

inert gas, revise the CoC description to 

remove the requirement for tamperindicating devices on the Vertical 

Concrete Casks, and include several 

editorial changes to improve the clarity 

of the documents associated with the 

NAC–MPC system. 

The alternative to this action is to 

withhold approval of Amendment No. 5 

and to require any part 72 licensee 

seeking to use Amendment No. 5 to 

request an exemption from the 

requirements of 10 CFR 72.212 and 

72.214. Under this alternative, each 

interested part 72 licensee would have 

to prepare, and the NRC would have to 

review, a separate exemption request, 

thereby increasing the administrative 

burden upon the NRC and the costs to 

each licensee. 

Approval of the direct final rule is 

consistent with previous NRC actions. 

Further, the direct final rule will have 

no adverse effect on public health and 

safety. This direct final rule has no 

significant identifiable impact or benefit 

on other Government agencies. Based on 

this regulatory analysis, the NRC 

concludes that the requirements of the 

direct final rule are commensurate with 

the NRC’s responsibilities for public 

health and safety and the common 

defense and security. No other available 

alternative is believed to be as 

satisfactory, and thus, this action is 

recommended. 

Regulatory Flexibility Certification 

Under the Regulatory Flexibility Act 

of 1980 (5 U.S.C. 605(b)), the NRC 

certifies that this rule will not, if issued, 

have a significant economic impact on 

a substantial number of small entities. 

This direct final rule affects only the 

licensing and operation of nuclear 

power plants, independent spent fuel 


cprice-sewell on PRODPC61 with RULES
26538 Federal Register / Vol. 72, No. 90 / Thursday, May 10, 2007 / Rules and Regulations 

storage facilities, and NAC. The 

companies that own these plants do not 

fall within the scope of the definition of 

‘‘small entities’’ set forth in the 

Regulatory Flexibility Act or the size 

standards established by the NRC (10 

CFR 2.810). 

Backfit Analysis 

The NRC has determined that the 

backfit rule (10 CFR 72.62) does not 

apply to this direct final rule because 

this amendment does not involve any 

provisions that would impose backfits 

as defined in 10 CFR Chapter I. 

Therefore, a backfit analysis is not 

required. 

Congressional Review Act 

Under the Congressional Review Act 

of 1996, the NRC has determined that 

this action is not a major rule and has 

verified this determination with the 

Office of Information and Regulatory 

Affairs, Office of Management and 

Budget.

Federal Aviation Administration 

14 CFR Part 39 

[Docket No. FAA–2007–27283; Directorate

Airworthiness Directives; General 

Electric Company (GE) GE90 Series 

Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for GE 

GE90–110B1, –113B, and –115B series 

turbofan engines with certain Turbine 

Center Frames (TCFs) installed. This AD 

requires removing certain TCFs, listed 

by part number (P/N) in this AD, from 

service before exceeding 14,300 flight 

cycles. This AD results from a report 

that GE inadvertently omitted some TCF 

P/Ns from the Airworthiness 

Limitations Section (ALS) of the engine 

manual. We are issuing this AD to 

prevent structural failure of the TCF 

with uncontained failure of low 

pressure turbine (LPT) rotating parts. 

Uncontained failure of the LPT rotating 

parts could result in damage to the 

airplane and possible loss of control of 

the airplane. 

DATES: This AD becomes effective June 

14, 2007. 

We must receive any comments on 

this AD by July 9, 2007.
