II. Rulemaking Procedure

Because the NRC considers this action

to be non-controversial, the NRC is 

publishing this proposed rule 

concurrently with a direct final rule in 

the Rules and Regulations section of this 

issue of the Federal Register. The direct 

final rule will become effective on April 

21, 2025. However, if the NRC receives 

any significant adverse comment by 

March 6, 2025, then the NRC will 

publish a document that withdraws the 

direct final rule. If the direct final rule 

is withdrawn, the NRC will address the 

comments in a subsequent final rule. In 

general, absent significant modifications 

to the proposed revisions requiring 

republication, the NRC will not initiate 


lotter on DSK11XQN23PROD with PROPOSALS1
Federal Register / Vol. 90, No. 22 / Tuesday, February 4, 2025 / Proposed Rules 8911 

a second comment period on this action 

in the event the direct final rule is 

withdrawn. 

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. A 

comment is adverse and significant if: 

(1) The comment opposes the rule and 

provides a reason sufficient to require a 

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

substantive response is required when: 

(a) The comment causes the NRC 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. 

(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 to 

make a change (other than editorial) to 

the rule, CoC, or technical 

specifications. 

For a more detailed discussion of the 

proposed rule changes and associated 

analyses, see the direct final rule 

published in the Rules and Regulations 

section of this issue of the Federal 

Register. 

III. Background 

Section 218(a) of the Nuclear Waste 

Policy Act of 1982, as amended, 

requires that ‘‘[t]he Secretary [of the 

Department of Energy] 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 

Nuclear Waste Policy Act states, in part, 

that ‘‘[t]he Commission shall, by rule, 

establish procedures for the licensing of 

any technology approved by the 

Commission under Section 219(a) [sic: 

218(a)] for use at the site of any civilian 

nuclear power reactor.’’ 

To implement this mandate, the 

Commission approved dry storage of 

spent nuclear fuel in NRC-approved 

casks under a general license by 

publishing a final rule that added a new 

subpart K in part 72 of title 10 of the 

Code of Federal Regulations (10 CFR) 

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 in 10 CFR 

part 72 entitled ‘‘Approval of Spent Fuel 

Storage Casks,’’ which contains 

procedures and criteria for obtaining 

NRC approval of spent fuel storage cask 

designs. The NRC subsequently issued a 

final rule on March 6, 2015 (80 FR 

12073), as corrected (80 FR 15679; 

March 25, 2015), that approved the 

Holtec International HI–STORM UMAX 

Canister Storage System design and 

added it to the list of NRC-approved 

cask designs in § 72.214 as CoC No. 

1040. 

IV. Plain Writing 

The Plain Writing Act of 2010 (Pub. 

L. 111–274) requires Federal agencies to 

write documents in a clear, concise, and 

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 31885). 

The NRC requests comment on the 

proposed rule with respect to clarity 

and effectiveness of the language used.

Confidential Business Information 

Confidential Business Information 

(CBI) is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to these special 

conditions contain commercial or 

financial information that is customarily 

treated as private, that you actually treat 

as private, and that is relevant or 

responsive to these special conditions, it 

is important that you clearly designate 

the submitted comments as CBI. Please 

mark each page of your submission 

containing CBI as ‘‘PROPIN.’’ The FAA 

will treat such marked submissions as 

confidential under the FOIA, and the 

indicated comments will not be placed 

in the public docket of these proposed 

special conditions. Send submissions 

containing CBI to the individual listed 

in the For Further Information Contact 

section above. Comments the FAA 

receives, which are not specifically 

designated as CBI, will be placed in the 

public docket for these proposed special 

conditions. 

Background 

On June 30, 2020, Gulfstream applied 

for an amendment to Type Certificate 

No. T00021AT to include the new 

Model GVII–G400 airplane. The 

Gulfstream Model GVII–G400 airplane, 

which is a derivative of the Model GVII– 

G500 airplane currently approved under 

Type Certificate No. T00021AT, is a 

twin-engine, transport-category, 

business jet, with a maximum seating 

for 19 passengers, and a maximum takeoff weight of 73,500 pounds. 

Type Certification Basis 

Under the provisions of 14 CFR 

21.101, Gulfstream must show that the 

Model GVII–G400 airplane meets the 

applicable provisions of the regulations 

listed in Type Certificate No. 

T00021AT, or the applicable regulations 

in effect on the date of application for 

the change, except for earlier 

amendments as agreed upon by the 

FAA. 

If the Administrator finds that the 

applicable airworthiness regulations 

(e.g., 14 CFR part 25) do not contain 

adequate or appropriate safety standards 

for the Gulfstream Model GVII–G400 

airplane because of a novel or unusual 

design feature, special conditions are 

prescribed under the provisions of 

§ 21.16. 

Special conditions are initially 

applicable to the model for which they 

are issued. Should the type certificate
