II. Introduction The NRC is considering issuance of an amendment to Renewed Facility Operating License Nos. NPF–72 and E:\FR\FM\28JNN1.SGM 28JNN1 khammond on DSKJM1Z7X2PROD with NOTICES Federal Register / Vol. 89, No. 125 / Friday, June 28, 2024 / Notices NPF–77, issued to Constellation Energy Generation, LLC, for the operation of Braidwood Station, Units 1 and 2 (Docket Nos. 50–456 and 50–457, respectively), located in Will County, IL. The proposed amendment would change TS SR 3.7.9.2 to allow a UHS temperature of less than or equal to 102.8 °F until September 30, 2024. Historical meteorological and atmospheric conditions have resulted in the UHS temperature approaching the TS limit. These conditions include elevated air temperatures, high humidity, and low wind speed. Specifically, the summer of 2020 brought hot weather and drought conditions to the northern Illinois area resulting in sustained elevated UHS temperatures. In anticipation of these conditions occurring during the summer months of 2024, this license amendment request would change the UHS temperature TS limit until September 30, 2024. Before issuance of the proposed license amendment, the NRC will need to make the findings required by the Atomic Energy Act of 1954, as amended (the Act), and NRC’s regulations. The NRC has made a proposed determination that the license amendment request involves no significant hazards consideration. Under the NRC’s regulations in section 50.92 of title 10 of the Code of Federal Regulations (10 CFR), ‘‘Issuance of amendment,’’ this means that operation of the facility in accordance with the proposed amendment would not (1) involve a significant increase in the probability or consequences of an accident previously evaluated; or (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a margin of safety. As required by 10 CFR 50.91(a), the licensee has provided its analysis of the issue of no significant hazards consideration, which is presented as follows: 1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated? Response: No. The likelihood of a malfunction of any systems, structures, or components (SSCs) supported by the UHS is not significantly increased by increasing the allowable UHS temperature from less than or equal to 102 °F to less than or equal to 102.8 °F. The UHS provides a heat sink for process and operating heat from safety related components during a transient or accident, as well as during normal operation. The proposed change does not make any physical changes to VerDate Sep<11>2014 19:25 Jun 27, 2024 Jkt 262001 any plant SSCs, nor does it alter any of the assumptions or conditions upon which the UHS is designed. The UHS is not an initiator of any analyzed accident. All equipment supported by the UHS has been evaluated to demonstrate that their performance and operation remains as described in the Updated Final Safety Analysis Report (UFSAR) with no increase in probability of failure or malfunction. The SSCs credited to mitigate the consequences of postulated design basis accidents remain capable of performing their design basis function. The change in maximum UHS temperature has been evaluated using the UFSAR described methods to demonstrate that the UHS remains capable of removing normal operating and post-accident heat. The change in UHS temperature and resulting containment response following a postulated design basis accident has been demonstrated to not be impacted. Additionally, all the UHS supported equipment, credited in the accident analysis to mitigate an accident, has been shown to continue to perform their design function as described in the UFSAR. Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated. 2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated? Response: No. The proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated. The proposed change does not introduce any new modes of plant operation, change the design function of any SSC, or change the mode of operation of any SSC. There are no new equipment failure modes or malfunctions created as affected SSCs continue to operate in the same manner as previously evaluated and have been evaluated to perform as designed at the increased UHS temperature and as assumed in the accident analysis. Additionally, accident initiators remain as described in the UFSAR and no new accident initiators are postulated as a result of the increase in UHS temperature. Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated. 3. Does the proposed amendment involve a significant reduction in a margin of safety? Response: No. The proposed change continues to ensure that the maximum temperature PO 00000 Frm 00146 Fmt 4703 Sfmt 4703 54083 of the cooling water supplied to the plant SSCs during a UHS design basis event remains within the evaluated equipment limits and capabilities assumed in the accident analysis. The proposed change does not result in any changes to plant equipment function, including setpoints and actuations. All equipment will function as designed in the plant safety analysis without any physical modifications. The proposed change does not alter a limiting condition for operation, limiting safety system setting, or safety limit specified in the Technical Specifications. The proposed change does not adversely impact the UHS inventory required to be available for the UFSAR described design basis accident involving the worst case 30-day period including losses for evaporation and seepage to support safe shutdown and cooldown of both Braidwood Station units. Additionally, the structural integrity of the UHS is not impacted and remains acceptable following the change, thereby ensuring that the assumptions for both UHS temperature and inventory remain valid. Therefore, since there is no adverse impact of this proposed change on the Braidwood Station safety analysis, there is no reduction in the margin of safety of the plant. The NRC staff has reviewed the licensee’s analysis and, based on this review, it appears that the three standards of 10 CFR 50.92(c) are satisfied. Therefore, the NRC staff proposes to determine that the license amendment request involves no significant hazards consideration. The NRC is seeking public comments on this proposed determination that the license amendment request involves no significant hazards consideration. Any comments received within 30 days after the date of publication of this notice will be considered in making any final determination. Normally, the Commission will not issue the amendment until the expiration of 60 days after the date of publication of this notice. The Commission may issue the license amendment before expiration of the 60day notice period if the Commission concludes the amendment involves no significant hazards consideration. In addition, the Commission may issue the amendment prior to the expiration of the 30-day comment period if circumstances change during the 30-day comment period such that failure to act in a timely way would result, for example, in derating or shutdown of the facility. If the Commission takes action prior to the expiration of either the comment period or the notice period, it E:\FR\FM\28JNN1.SGM 28JNN1 54084 Federal Register / Vol. 89, No. 125 / Friday, June 28, 2024 / Notices khammond on DSKJM1Z7X2PROD with NOTICES will publish in the Federal Register a notice of issuance. If the Commission makes a final no significant hazards consideration determination, any hearing will take place after issuance. The Commission expects that the need to take this action will occur very infrequently. III. Opportunity To Request a Hearing and Petition for Leave To Intervene Within 60 days after the date of publication of this notice, any person (petitioner) whose interest may be affected by this action may file a request for a hearing and petition for leave to intervene (petition) with respect to the action. Petitions shall be filed in accordance with the Commission’s ‘‘Agency Rules of Practice and Procedure’’ in 10 CFR part 2. Interested persons should consult 10 CFR 2.309. If a petition is filed, the presiding officer will rule on the petition and, if appropriate, a notice of a hearing will be issued. Petitions must be filed no later than 60 days from the date of publication of this notice in accordance with the filing instructions in the ‘‘Electronic Submissions (E-Filing)’’ section of this document. Petitions and motions for leave to file new or amended contentions that are filed after the deadline will not be entertained absent a determination by the presiding officer that the filing demonstrates good cause by satisfying the three factors in 10 CFR 2.309(c)(1)(i) through (iii). If a hearing is requested and the Commission has not made a final determination on the issue of no significant hazards consideration, the Commission will make a final determination on the issue of no significant hazards consideration, which will serve to establish when the hearing is held. If the final determination is that the amendment request involves no significant hazards consideration, the Commission may issue the amendment and make it immediately effective, notwithstanding the request for a hearing. Any hearing would take place after issuance of the amendment. If the final determination is that the amendment request involves a significant hazards consideration, then any hearing held would take place before the issuance of the amendment unless the Commission finds an imminent danger to the health or safety of the public, in which case it will issue an appropriate order or rule under 10 CFR part 2. A State, local governmental body, Federally recognized Indian Tribe, or designated agency thereof, may submit a petition to the Commission to VerDate Sep<11>2014 19:25 Jun 27, 2024 Jkt 262001 participate as a party under 10 CFR 2.309(h) no later than 60 days from the date of publication of this notice. Alternatively, a State, local governmental body, Federally recognized Indian Tribe, or designated agency thereof may participate as a nonparty under 10 CFR 2.315(c). For information about filing a petition and about participation by a person not a party under 10 CFR 2.315, see ADAMS Accession No. ML20340A053. (https:// adamswebsearch2.nrc.gov/webSearch2/ main.jsp?Accession Number=ML20340A053) and on the NRC’s public website at https:// www.nrc.gov/about-nrc/regulatory/ adjudicatory/hearing.html#participate. IV. Electronic Submissions and E-Filing All documents filed in NRC adjudicatory proceedings, including documents filed by an interested State, local governmental body, Federally recognized Indian Tribe, or designated agency thereof that requests to participate under 10 CFR 2.315(c), must be filed in accordance with 10 CFR 2.302. The E-Filing process requires participants to submit and serve all adjudicatory documents over the internet, or in some cases, to mail copies on electronic storage media, unless an exemption permitting an alternative filing method, as further discussed, is granted. Detailed guidance on electronic submissions is located in the ‘‘Guidance for Electronic Submissions to the NRC’’ (ADAMS Accession No. ML13031A056) and on the NRC’s public website at https://www.nrc.gov/site-help/esubmittals.html. To comply with the procedural requirements of E-Filing, at least 10 days prior to the filing deadline, the participant should contact the Office of the Secretary by email at Hearing.Docket@nrc.gov, or by telephone at 301–415–1677, to (1) request a digital identification (ID) certificate, which allows the participant (or its counsel or representative) to digitally sign submissions and access the E-Filing system for any proceeding in which it is participating; and (2) advise the Secretary that the participant will be submitting a petition or other adjudicatory document (even in instances in which the participant, or its counsel or representative, already holds an NRC-issued digital ID certificate). Based upon this information, the Secretary will establish an electronic docket for the proceeding if the Secretary has not already established an electronic docket. Information about applying for a digital ID certificate is available on the NRC’s public website at https:// PO 00000 Frm 00147 Fmt 4703 Sfmt 4703 www.nrc.gov/site-help/e-submittals/ getting-started.html. After a digital ID certificate is obtained and a docket created, the participant must submit adjudicatory documents in Portable Document Format. Guidance on submissions is available on the NRC’s public website at https://www.nrc.gov/ site-help/electronic-sub-ref-mat.html. A filing is considered complete at the time the document is submitted through the NRC’s E-Filing system. To be timely, an electronic filing must be submitted to the E-Filing system no later than 11:59 p.m. ET on the due date. Upon receipt of a transmission, the E-Filing system time-stamps the document and sends the submitter an email confirming receipt of the document. The E-Filing system also distributes an email that provides access to the document to the NRC’s Office of the General Counsel and any others who have advised the Office of the Secretary that they wish to participate in the proceeding, so that the filer need not serve the document on those participants separately. Therefore, applicants and other participants (or their counsel or representative) must apply for and receive a digital ID certificate before adjudicatory documents are filed to obtain access to the documents via the E-Filing system. A person filing electronically using the NRC’s adjudicatory E-Filing system may seek assistance by contacting the NRC’s Electronic Filing Help Desk through the ‘‘Contact Us’’ link located on the NRC’s public website at https:// www.nrc.gov/site-help/esubmittals.html, by email to MSHD.Resource@nrc.gov, or by a tollfree call at 1–866–672–7640. The NRC Electronic Filing Help Desk is available between 9 a.m. and 6 p.m., ET, Monday through Friday, except Federal holidays. Participants who believe that they have good cause for not submitting documents electronically must file an exemption request, in accordance with 10 CFR 2.302(g), with their initial paper filing stating why there is good cause for not filing electronically and requesting authorization to continue to submit documents in paper format. Such filings must be submitted in accordance with 10 CFR 2.302(b)–(d). Participants filing adjudicatory documents in this manner are responsible for serving their documents on all other participants. Participants granted an exemption under 10 CFR 2.302(g)(2) must still meet the electronic formatting requirement in 10 CFR 2.302(g)(1), unless the participant also seeks and is granted an exemption from 10 CFR 2.302(g)(1). Documents submitted in adjudicatory proceedings will appear in the NRC’s electronic hearing docket, which is E:\FR\FM\28JNN1.SGM 28JNN1 Federal Register / Vol. 89, No. 125 / Friday, June 28, 2024 / Notices publicly available at https:// adams.nrc.gov/ehd, unless excluded pursuant to an order of the presiding officer. If you do not have an NRCissued digital ID certificate as previously described, click ‘‘cancel’’ when the link requests certificates and you will be automatically directed to the NRC’s electronic hearing docket where you will be able to access any publicly available documents in a particular hearing docket. Participants are requested not to include personal privacy information such as social security numbers, home addresses, or personal phone numbers in their filings unless an NRC regulation or other law requires submission of such information. With respect to copyrighted works, except for limited excerpts that serve the purpose of the adjudicatory filings and would constitute a Fair Use application, participants should not include copyrighted materials in their submission. For further details with respect to this action, see the application for license amendment dated June 4, 2024 (ADAMS Accession No. ML24156A245).

II. Introduction

    The NRC is considering issuance of an amendment to Renewed Facility 
Operating License Nos. NPF-72 and

[[Page 54083]]

NPF-77, issued to Constellation Energy Generation, LLC, for the 
operation of Braidwood Station, Units 1 and 2 (Docket Nos. 50-456 and 
50-457, respectively), located in Will County, IL. The proposed 
amendment would change TS SR 3.7.9.2 to allow a UHS temperature of less 
than or equal to 102.8 [deg]F until September 30, 2024.
    Historical meteorological and atmospheric conditions have resulted 
in the UHS temperature approaching the TS limit. These conditions 
include elevated air temperatures, high humidity, and low wind speed. 
Specifically, the summer of 2020 brought hot weather and drought 
conditions to the northern Illinois area resulting in sustained 
elevated UHS temperatures. In anticipation of these conditions 
occurring during the summer months of 2024, this license amendment 
request would change the UHS temperature TS limit until September 30, 
2024.
    Before issuance of the proposed license amendment, the NRC will 
need to make the findings required by the Atomic Energy Act of 1954, as 
amended (the Act), and NRC's regulations.
    The NRC has made a proposed determination that the license 
amendment request involves no significant hazards consideration. Under 
the NRC's regulations in section 50.92 of title 10 of the Code of 
Federal Regulations (10 CFR), ``Issuance of amendment,'' this means 
that operation of the facility in accordance with the proposed 
amendment would not (1) involve a significant increase in the 
probability or consequences of an accident previously evaluated; or (2) 
create the possibility of a new or different kind of accident from any 
accident previously evaluated; or (3) involve a significant reduction 
in a margin of safety. As required by 10 CFR 50.91(a), the licensee has 
provided its analysis of the issue of no significant hazards 
consideration, which is presented as follows:
    1. Does the proposed amendment involve a significant increase in 
the probability or consequences of an accident previously evaluated?
    Response: No.
    The likelihood of a malfunction of any systems, structures, or 
components (SSCs) supported by the UHS is not significantly increased 
by increasing the allowable UHS temperature from less than or equal to 
102 [deg]F to less than or equal to 102.8 [deg]F. The UHS provides a 
heat sink for process and operating heat from safety related components 
during a transient or accident, as well as during normal operation. The 
proposed change does not make any physical changes to any plant SSCs, 
nor does it alter any of the assumptions or conditions upon which the 
UHS is designed. The UHS is not an initiator of any analyzed accident. 
All equipment supported by the UHS has been evaluated to demonstrate 
that their performance and operation remains as described in the 
Updated Final Safety Analysis Report (UFSAR) with no increase in 
probability of failure or malfunction.
    The SSCs credited to mitigate the consequences of postulated design 
basis accidents remain capable of performing their design basis 
function. The change in maximum UHS temperature has been evaluated 
using the UFSAR described methods to demonstrate that the UHS remains 
capable of removing normal operating and post-accident heat. The change 
in UHS temperature and resulting containment response following a 
postulated design basis accident has been demonstrated to not be 
impacted. Additionally, all the UHS supported equipment, credited in 
the accident analysis to mitigate an accident, has been shown to 
continue to perform their design function as described in the UFSAR.
    Therefore, the proposed change does not involve a significant 
increase in the probability or consequences of an accident previously 
evaluated.
    2. Does the proposed amendment create the possibility of a new or 
different kind of accident from any accident previously evaluated?
    Response: No.
    The proposed change does not create the possibility of a new or 
different kind of accident from any accident previously evaluated. The 
proposed change does not introduce any new modes of plant operation, 
change the design function of any SSC, or change the mode of operation 
of any SSC. There are no new equipment failure modes or malfunctions 
created as affected SSCs continue to operate in the same manner as 
previously evaluated and have been evaluated to perform as designed at 
the increased UHS temperature and as assumed in the accident analysis. 
Additionally, accident initiators remain as described in the UFSAR and 
no new accident initiators are postulated as a result of the increase 
in UHS temperature.
    Therefore, the proposed change does not create the possibility of a 
new or different kind of accident from any previously evaluated.
    3. Does the proposed amendment involve a significant reduction in a 
margin of safety?
    Response: No.
    The proposed change continues to ensure that the maximum 
temperature of the cooling water supplied to the plant SSCs during a 
UHS design basis event remains within the evaluated equipment limits 
and capabilities assumed in the accident analysis. The proposed change 
does not result in any changes to plant equipment function, including 
setpoints and actuations. All equipment will function as designed in 
the plant safety analysis without any physical modifications. The 
proposed change does not alter a limiting condition for operation, 
limiting safety system setting, or safety limit specified in the 
Technical Specifications.
    The proposed change does not adversely impact the UHS inventory 
required to be available for the UFSAR described design basis accident 
involving the worst case 30-day period including losses for evaporation 
and seepage to support safe shutdown and cooldown of both Braidwood 
Station units. Additionally, the structural integrity of the UHS is not 
impacted and remains acceptable following the change, thereby ensuring 
that the assumptions for both UHS temperature and inventory remain 
valid.
    Therefore, since there is no adverse impact of this proposed change 
on the Braidwood Station safety analysis, there is no reduction in the 
margin of safety of the plant.
    The NRC staff has reviewed the licensee's analysis and, based on 
this review, it appears that the three standards of 10 CFR 50.92(c) are 
satisfied. Therefore, the NRC staff proposes to determine that the 
license amendment request involves no significant hazards 
consideration.
    The NRC is seeking public comments on this proposed determination 
that the license amendment request involves no significant hazards 
consideration. Any comments received within 30 days after the date of 
publication of this notice will be considered in making any final 
determination.
    Normally, the Commission will not issue the amendment until the 
expiration of 60 days after the date of publication of this notice. The 
Commission may issue the license amendment before expiration of the 60-
day notice period if the Commission concludes the amendment involves no 
significant hazards consideration. In addition, the Commission may 
issue the amendment prior to the expiration of the 30-day comment 
period if circumstances change during the 30-day comment period such 
that failure to act in a timely way would result, for example, in 
derating or shutdown of the facility. If the Commission takes action 
prior to the expiration of either the comment period or the notice 
period, it

[[Page 54084]]

will publish in the Federal Register a notice of issuance. If the 
Commission makes a final no significant hazards consideration 
determination, any hearing will take place after issuance. The 
Commission expects that the need to take this action will occur very 
infrequently.

III. Opportunity To Request a Hearing and Petition for Leave To 
Intervene

    Within 60 days after the date of publication of this notice, any 
person (petitioner) whose interest may be affected by this action may 
file a request for a hearing and petition for leave to intervene 
(petition) with respect to the action. Petitions shall be filed in 
accordance with the Commission's ``Agency Rules of Practice and 
Procedure'' in 10 CFR part 2. Interested persons should consult 10 CFR 
2.309. If a petition is filed, the presiding officer will rule on the 
petition and, if appropriate, a notice of a hearing will be issued.
    Petitions must be filed no later than 60 days from the date of 
publication of this notice in accordance with the filing instructions 
in the ``Electronic Submissions (E-Filing)'' section of this document. 
Petitions and motions for leave to file new or amended contentions that 
are filed after the deadline will not be entertained absent a 
determination by the presiding officer that the filing demonstrates 
good cause by satisfying the three factors in 10 CFR 2.309(c)(1)(i) 
through (iii).
    If a hearing is requested and the Commission has not made a final 
determination on the issue of no significant hazards consideration, the 
Commission will make a final determination on the issue of no 
significant hazards consideration, which will serve to establish when 
the hearing is held. If the final determination is that the amendment 
request involves no significant hazards consideration, the Commission 
may issue the amendment and make it immediately effective, 
notwithstanding the request for a hearing. Any hearing would take place 
after issuance of the amendment. If the final determination is that the 
amendment request involves a significant hazards consideration, then 
any hearing held would take place before the issuance of the amendment 
unless the Commission finds an imminent danger to the health or safety 
of the public, in which case it will issue an appropriate order or rule 
under 10 CFR part 2.
    A State, local governmental body, Federally recognized Indian 
Tribe, or designated agency thereof, may submit a petition to the 
Commission to participate as a party under 10 CFR 2.309(h) no later 
than 60 days from the date of publication of this notice. 
Alternatively, a State, local governmental body, Federally recognized 
Indian Tribe, or designated agency thereof may participate as a non-
party under 10 CFR 2.315(c).
    For information about filing a petition and about participation by 
a person not a party under 10 CFR 2.315, see ADAMS Accession No. 
ML20340A053. (https://adamswebsearch2.nrc.gov/webSearch2/main.jsp?AccessionNumber=ML20340A053) and on the NRC's public website 
at https://www.nrc.gov/about-nrc/regulatory/adjudicatory/hearing.html#participate.

IV. Electronic Submissions and E-Filing

    All documents filed in NRC adjudicatory proceedings, including 
documents filed by an interested State, local governmental body, 
Federally recognized Indian Tribe, or designated agency thereof that 
requests to participate under 10 CFR 2.315(c), must be filed in 
accordance with 10 CFR 2.302. The E-Filing process requires 
participants to submit and serve all adjudicatory documents over the 
internet, or in some cases, to mail copies on electronic storage media, 
unless an exemption permitting an alternative filing method, as further 
discussed, is granted. Detailed guidance on electronic submissions is 
located in the ``Guidance for Electronic Submissions to the NRC'' 
(ADAMS Accession No. ML13031A056) and on the NRC's public website at 
https://www.nrc.gov/site-help/e-submittals.html.
    To comply with the procedural requirements of E-Filing, at least 10 
days prior to the filing deadline, the participant should contact the 
Office of the Secretary by email at [email protected], or by 
telephone at 301-415-1677, to (1) request a digital identification (ID) 
certificate, which allows the participant (or its counsel or 
representative) to digitally sign submissions and access the E-Filing 
system for any proceeding in which it is participating; and (2) advise 
the Secretary that the participant will be submitting a petition or 
other adjudicatory document (even in instances in which the 
participant, or its counsel or representative, already holds an NRC-
issued digital ID certificate). Based upon this information, the 
Secretary will establish an electronic docket for the proceeding if the 
Secretary has not already established an electronic docket.
    Information about applying for a digital ID certificate is 
available on the NRC's public website at https://www.nrc.gov/site-help/e-submittals/getting-started.html. After a digital ID certificate is 
obtained and a docket created, the participant must submit adjudicatory 
documents in Portable Document Format. Guidance on submissions is 
available on the NRC's public website at https://www.nrc.gov/site-help/electronic-sub-ref-mat.html. A filing is considered complete at the 
time the document is submitted through the NRC's E-Filing system. To be 
timely, an electronic filing must be submitted to the E-Filing system 
no later than 11:59 p.m. ET on the due date. Upon receipt of a 
transmission, the E-Filing system time-stamps the document and sends 
the submitter an email confirming receipt of the document. The E-Filing 
system also distributes an email that provides access to the document 
to the NRC's Office of the General Counsel and any others who have 
advised the Office of the Secretary that they wish to participate in 
the proceeding, so that the filer need not serve the document on those 
participants separately. Therefore, applicants and other participants 
(or their counsel or representative) must apply for and receive a 
digital ID certificate before adjudicatory documents are filed to 
obtain access to the documents via the E-Filing system.
    A person filing electronically using the NRC's adjudicatory E-
Filing system may seek assistance by contacting the NRC's Electronic 
Filing Help Desk through the ``Contact Us'' link located on the NRC's 
public website at https://www.nrc.gov/site-help/e-submittals.html, by 
email to [email protected], or by a toll-free call at 1-866-672-
7640. The NRC Electronic Filing Help Desk is available between 9 a.m. 
and 6 p.m., ET, Monday through Friday, except Federal holidays.
    Participants who believe that they have good cause for not 
submitting documents electronically must file an exemption request, in 
accordance with 10 CFR 2.302(g), with their initial paper filing 
stating why there is good cause for not filing electronically and 
requesting authorization to continue to submit documents in paper 
format. Such filings must be submitted in accordance with 10 CFR 
2.302(b)-(d). Participants filing adjudicatory documents in this manner 
are responsible for serving their documents on all other participants. 
Participants granted an exemption under 10 CFR 2.302(g)(2) must still 
meet the electronic formatting requirement in 10 CFR 2.302(g)(1), 
unless the participant also seeks and is granted an exemption from 10 
CFR 2.302(g)(1).
    Documents submitted in adjudicatory proceedings will appear in the 
NRC's electronic hearing docket, which is

[[Page 54085]]

publicly available at https://adams.nrc.gov/ehd, unless excluded 
pursuant to an order of the presiding officer. If you do not have an 
NRC-issued digital ID certificate as previously described, click 
``cancel'' when the link requests certificates and you will be 
automatically directed to the NRC's electronic hearing docket where you 
will be able to access any publicly available documents in a particular 
hearing docket. Participants are requested not to include personal 
privacy information such as social security numbers, home addresses, or 
personal phone numbers in their filings unless an NRC regulation or 
other law requires submission of such information. With respect to 
copyrighted works, except for limited excerpts that serve the purpose 
of the adjudicatory filings and would constitute a Fair Use 
application, participants should not include copyrighted materials in 
their submission.
    For further details with respect to this action, see the 
application for license amendment dated June 4, 2024 (ADAMS Accession 
No. ML24156A245).
