II. Introduction

    The NRC is considering issuance of amendments to the facility 
operating licenses for the following boiling-water reactors (BWRs) 
operated by Exelon Generation Company, LLC: Dresden, Units 2 and 3, 
located in Grundy County, Illinois; LaSalle, Units 1 and 2, located in 
LaSalle County, Illinois; Limerick, Units 1 and 2, located in 
Montgomery County, Pennsylvania; Nine Mile Point, Unit 2, located in 
Oswego County, New York; Peach Bottom, Units 2 and 3, located in York 
and Lancaster Counties, Pennsylvania; and Quad Cities, Units 1 and 2, 
located in Rock Island County, Illinois.
    The proposed amendments would revise certain TS requirements for 
the following physical parameters: (1) The drywell-to-suppression 
chamber differential pressure at Dresden and Quad Cities; (2) the 
primary containment oxygen concentration at Dresden, LaSalle, Nine Mile 
Point, Peach Bottom, and Quad Cities; and (3) the drywell and 
suppression chamber oxygen concentration at Limerick. The proposed 
changes are based, in part, on Technical Specifications Task Force 
(TSTF) traveler TSTF-568, Revision 2, ``Revise Applicability of BWR/4 
TS 3.6.2.5 and TS 3.6.3.2'' (ADAMS Accession No. ML19141A122).
    Before any issuance of the proposed license amendments, 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 Sec.  50.92 of title 10 of the Code of Federal 
Regulations (10 CFR), this means that operation of the facilities in 
accordance with the proposed amendments 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. The NRC staff has reviewed the 
licensee's analysis against the standards of 10 CFR 50.92(c). The NRC 
staff's analysis is presented below:
    1. Does the proposed change involve a significant increase in the 
probability or consequences of an accident previously evaluated?
    Response: No.
    The proposed change revises certain TS requirements for the 
following physical parameters: (1) The drywell-to-suppression chamber 
differential pressure at Dresden and Quad Cities; (2) the primary 
containment oxygen concentration at Dresden, LaSalle, Nine Mile Point, 
Peach Bottom, and Quad Cities; and (3) the drywell and suppression 
chamber oxygen concentration at Limerick. Specifically, the proposed 
change revises the applicability of the limiting conditions for 
operation (LCOs) for these parameters and the remedial actions to be 
taken when these LCOs are not met. The TS limits on these parameters 
are not affected by the proposed change. These parameters are not 
initiators to any accident previously evaluated. As a result, the 
probability of any accident previously evaluated is not affected by the 
proposed change.
    The mitigation of some accidents previously evaluated includes 
assumptions regarding these physical parameters. The applicability of 
the LCOs related to oxygen concentration is changed from Mode 1 
(Operational Condition 1 for Limerick) when thermal power is greater 
than 15 percent to Modes 1 and 2 (Operational Conditions 1 and 2 for 
Limerick). This expands the applicability of the LCOs related to oxygen 
concentration for each facility and will not affect the consequences of 
an accident.
    The existing exceptions in the applicability of the LCOs for the 
subject physical parameters are removed. For each subject parameter, if 
the LCO is not met, then the licensee must either restore the parameter 
to within the specified limit or be in a mode or condition where the 
LCO is not applicable. The proposed change includes increasing the 
completion times for these actions. The consequences of an event that 
could affect the subject parameters are no different during the 
proposed completion times than the consequences of the same event 
during the existing completion times. A note referencing LCO 3.0.4.c is 
added to the TS actions to permit entering a mode or condition where 
the LCOs for the subject parameters are applicable but not met. The 
addition of LCO 3.0.4.c has no effect on the consequences of an 
accident. The changes to the completion times and addition of LCO 
3.0.4.c replace the existing applicability exceptions.
    Therefore, the proposed change does not involve a significant 
increase in the probability or consequences of an accident previously 
evaluated.
    2. Does the proposed change create the possibility of a new or 
different kind of accident from any accident previously evaluated?
    Response: No.
    The proposed change revises the TS requirements for the following 
physical parameters: (1) The drywell-to-suppression chamber 
differential pressure at Dresden and Quad Cities; (2) the primary 
containment oxygen concentration at Dresden, LaSalle, Nine Mile Point, 
Peach Bottom, and Quad Cities; and (3) the drywell and suppression 
chamber oxygen concentration at Limerick. Specifically, the proposed 
change revises the applicability of the LCOs for these parameters and 
the actions for when these LCOs are not met. The proposed change does 
not involve a physical alteration of these plants (i.e., no new or 
different type of equipment will be installed). No credible new failure 
mechanisms, malfunctions, or accident initiators that would have been 
considered a design-basis accident in the Updated Final Safety Analysis 
Report for these plants are created because hydrogen generation is not 
risk significant for design-basis accidents.
    Therefore, the proposed change does not create the possibility of a 
new or different kind of accident from any accident previously 
evaluated.
    3. Does the proposed change involve a significant reduction in a 
margin of safety?
    Response: No.
    The proposed change revises the TS requirements for the following 
physical parameters: (1) The drywell-to-suppression chamber 
differential

[[Page 40325]]

pressure at Dresden and Quad Cities; (2) the primary containment oxygen 
concentration at Dresden, LaSalle, Nine Mile Point, Peach Bottom, and 
Quad Cities; and (3) the drywell and suppression chamber oxygen 
concentration at Limerick. Specifically, the proposed change revises 
the applicability of the LCOs for these parameters and the actions for 
when these LCOs are not met. No safety limits are affected. No LCOs or 
physical parameter limits are affected. The TS requirements for these 
parameters assure sufficient safety margins are maintained, and that 
the design, operation, surveillance methods, and acceptance criteria 
specified in applicable codes and standards (or alternatives approved 
for use by the NRC) will continue to be met as described in the 
licensing basis for each plant. The proposed change does not adversely 
affect existing plant safety margins or the reliability of the 
equipment assumed to operate in the safety analysis. As such, there are 
no changes being made to safety analysis assumptions, safety limits, or 
limiting safety system settings that would adversely affect plant 
safety.
    Therefore, the proposed change does not involve a significant 
reduction in a margin of safety.
    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 amendments until the 
expiration of 60 days after the date of publication of this notice. The 
Commission may issue the license amendments before expiration of the 
60-day notice period if the Commission concludes the amendments involve 
no significant hazards consideration. In addition, the Commission may 
issue the amendments 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 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 
persons (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 a 
current copy of 10 CFR 2.309. The NRC's regulations are accessible 
electronically from the NRC Library on the NRC's website at https://www.nrc.gov/reading-rm/doc-collections/cfr/. If a petition is filed, 
the Commission or a presiding officer will rule on the petition and, if 
appropriate, a notice of a hearing will be issued.
    As required by 10 CFR 2.309(d) the petition should specifically 
explain the reasons why intervention should be permitted with 
particular reference to the following general requirements for 
standing: (1) The name, address, and telephone number of the 
petitioner; (2) the nature of the petitioner's right to be made a party 
to the proceeding; (3) the nature and extent of the petitioner's 
property, financial, or other interest in the proceeding; and (4) the 
possible effect of any decision or order which may be entered in the 
proceeding on the petitioner's interest.
    In accordance with 10 CFR 2.309(f), the petition must also set 
forth the specific contentions which the petitioner seeks to have 
litigated in the proceeding. Each contention must consist of a specific 
statement of the issue of law or fact to be raised or controverted. In 
addition, the petitioner must provide a brief explanation of the bases 
for the contention and a concise statement of the alleged facts or 
expert opinion which support the contention and on which the petitioner 
intends to rely in proving the contention at the hearing. The 
petitioner must also provide references to the specific sources and 
documents on which the petitioner intends to rely to support its 
position on the issue. The petition must include sufficient information 
to show that a genuine dispute exists with the applicant or licensee on 
a material issue of law or fact. Contentions must be limited to matters 
within the scope of the proceeding. The contention must be one which, 
if proven, would entitle the petitioner to relief. A petitioner who 
fails to satisfy the requirements at 10 CFR 2.309(f) with respect to at 
least one contention will not be permitted to participate as a party.
    Those permitted to intervene become parties to the proceeding, 
subject to any limitations in the order granting leave to intervene. 
Parties have the opportunity to participate fully in the conduct of the 
hearing with respect to resolution of that party's admitted 
contentions, including the opportunity to present evidence, consistent 
with the NRC's regulations, policies, and procedures.
    Petitions must be filed no later than 60 days from the date of 
publication of this notice. 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). The petition must be filed in 
accordance with the filing instructions in the ``Electronic Submissions 
(E-Filing)'' section of this document.
    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. The final determination 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 amendments and make them 
immediately effective, notwithstanding the request for a hearing. Any 
hearing would take place after issuance of the amendments. 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 amendments 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 agency thereof, may submit a petition to the Commission to 
participate as a party under 10 CFR 2.309(h)(1). The petition should 
state the nature and extent of the petitioner's interest in the 
proceeding. The petition should be submitted to the Commission no later 
than 60 days from the date of publication of this notice. The petition 
must be filed in accordance with the filing instructions in the 
``Electronic Submissions (E-Filing)''

[[Page 40326]]

section of this document, and should meet the requirements for 
petitions set forth in this section, except that under 10 CFR 
2.309(h)(2) a State, local governmental body, or Federally-recognized 
Indian Tribe, or agency thereof does not need to address the standing 
requirements in 10 CFR 2.309(d) if the facility is located within its 
boundaries. Alternatively, a State, local governmental body, Federally-
recognized Indian Tribe, or agency thereof may participate as a non-
party under 10 CFR 2.315(c).
    If a hearing is granted, any person who is not a party to the 
proceeding and is not affiliated with or represented by a party may, at 
the discretion of the presiding officer, be permitted to make a limited 
appearance pursuant to the provisions of 10 CFR 2.315(a). A person 
making a limited appearance may make an oral or written statement of 
his or her position on the issues but may not otherwise participate in 
the proceeding. A limited appearance may be made at any session of the 
hearing or at any prehearing conference, subject to the limits and 
conditions as may be imposed by the presiding officer. Details 
regarding the opportunity to make a limited appearance will be provided 
by the presiding officer if such sessions are scheduled.

IV. Electronic Submissions (E-Filing)

    All documents filed in NRC adjudicatory proceedings, including a 
request for hearing and petition for leave to intervene (petition), any 
motion or other document filed in the proceeding prior to the 
submission of a request for hearing or petition to intervene, and 
documents filed by interested governmental entities that request to 
participate under 10 CFR 2.315(c), must be filed in accordance with the 
NRC's E-Filing rule (72 FR 49139; August 28, 2007, as amended at 77 FR 
46562; August 3, 2012). 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. Detailed 
guidance on making electronic submissions may be found in the Guidance 
for Electronic Submissions to the NRC and on the NRC website at https://www.nrc.gov/site-help/e-submittals.html. Participants may not submit 
paper copies of their filings unless they seek an exemption in 
accordance with the procedures described below.
    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 hearing in this 
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. Once a participant has obtained a 
digital ID certificate and a docket has been created, the participant 
can then submit adjudicatory documents. Submissions must be in Portable 
Document Format (PDF). Additional guidance on PDF 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. Eastern Time on the due date. Upon receipt of 
a transmission, the E-Filing system time-stamps the document and sends 
the submitter an email notice confirming receipt of the document. The 
E-Filing system also distributes an email notice 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 so that they can 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., Eastern Time, Monday through Friday, excluding government 
holidays.
    Participants who believe that they have a 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 by: (1) First class mail 
addressed to the Office of the Secretary of the Commission, U.S. 
Nuclear Regulatory Commission, Washington, DC 20555-0001, Attention: 
Rulemaking and Adjudications Staff; or (2) courier, express mail, or 
expedited delivery service to the Office of the Secretary, 11555 
Rockville Pike, Rockville, Maryland 20852, Attention: Rulemaking and 
Adjudications Staff. Participants filing adjudicatory documents in this 
manner are responsible for serving the document on all other 
participants. Filing is considered complete by first-class mail as of 
the time of deposit in the mail, or by courier, express mail, or 
expedited delivery service upon depositing the document with the 
provider of the service. A presiding officer, having granted an 
exemption request from using E-Filing, may require a participant or 
party to use E-Filing if the presiding officer subsequently determines 
that the reason for granting the exemption from use of E-Filing no 
longer exists.
    Documents submitted in adjudicatory proceedings will appear in the 
NRC's electronic hearing docket which is available to the public at 
https://adams.nrc.gov/ehd, unless excluded pursuant to an order of the 
Commission or the presiding officer. If you do not have an NRC-issued 
digital ID certificate as described above, click ``cancel'' when the 
link requests certificates and you will be automatically directed to 
the NRC's electronic hearing dockets 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. For example, in some 
instances, individuals provide home addresses in order to demonstrate 
proximity to a facility or site. With respect to copyrighted works, 
except for limited excerpts that serve the purpose of the adjudicatory 
filings and would constitute a Fair Use application,
