Download as PDF khammond on DSKJM1Z7X2PROD with NOTICES 46024 Federal Register / Vol. 86, No. 156 / Tuesday, August 17, 2021 / Notices All applicants must provide answers to the application questions in GrantEase and upload the following documents: • A draft subgrant agreement (with the required terms provided in LSC’s Subgrant Agreement Template); and • A subgrant budget (using LSC’s Subgrant Budget Template). Applicants seeking to subgrant to a new subrecipient that is not a current LSC grantee or applying to renew a subgrant with an organization that is not a current LSC grantee in a year in which the applicant was not already required to submit the documents listed below as a part of an application to subgant LSC Basic Field funds, must also upload: • The subrecipient’s accounting manual; • The subrecipient’s most recent audited financial statements; • The subrecipient’s current cost allocation policy (if not in the accounting manual); • The subrecipient’s 45 CFR 1635.3(c) recordkeeping policy (if not in the accounting manual). A list of subgrant application questions, the Subgrant Agreement Template, and the Subgrant Budget Template are available on LSC’s website at https://www.lsc.gov/grants-granteeresources/grantee-guidance/how-applysubgrant. LSC encourages applicants to use LSC’s Subgrant Agreement Template as a model subgrant agreement. If the applicant does not use LSC’s Template, the proposed agreement must include, at a minimum, the substance of the provisions of the Template. Once submitted, LSC will evaluate the application and provide applicants with instructions on any needed modifications to the submitted documents or Draft Agreement provided with the application. The applicant must then upload a final and signed subgrant agreement through GrantEase by the date requested. As required by 45 CFR 1627.4(b)(3), LSC will inform applicants of its decision to disapprove, approve, or request modifications to the subgrant no later than the subgrant’s proposed effective date.

Additional Information The NRC is issuing for public comment a DG in the NRC’s ‘‘Regulatory Guide’’ series. This series was developed to describe methods that are acceptable to the NRC staff for implementing specific parts of the agency’s regulations, to explain techniques that the staff uses in evaluating specific issues or postulated events, and to describe information that the staff needs in its review of applications for permits and licenses. This DG, identified by its task number, DG–4030, titled, ‘‘Use of ARCON Methodology for Calculation of Accident-Related Offsite Atmospheric Dispersion Factors,’’ is a proposed new RG 4.28 (ADAMS Accession No. ML21165A005). This proposed new RG 4.28 provides guidance to industry for complying with and implementing the NRC requirements by endorsing the use of the ARCON computer code to calculate offsite dispersion values out to distances of 1,200 m (3,937 ft) that could include the exclusion area boundary and/or low-population zone. RG 1.194 (ADAMS Accession No. ML031530505) endorses the use of the ARCON96 computer code for calculating accident-related onsite (control room and technical support center) atmospheric dispersion values which are direct inputs to habitability dose assessments. In addition, RG 1.145, ‘‘Atmospheric Dispersion Models for Potential Accident Consequence Assessments at Nuclear Power Plants’’ (ADAMS Accession No. ML12216A014), provides the present methodology incorporated into the PAVAN computer code, as reviewed by the staff using NUREG–0800 at https://www.nrc.gov/ reading-rm/doc-collections/nuregs/staff/ sr0800/ (ADAMS Accession No. ML070810350), SRP Section 2.3.4 for calculating accident-related related, offsite atmospheric dispersion values.

Use of ARCON Methodology for Calculation of Accident-Related 
Offsite Atmospheric Dispersion Factors

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft regulatory guide; request for comment.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for 
public comment draft regulatory guide (DG), DG-4030, ``Use of ARCON 
Methodology for Calculation of Accident-Related Offsite Atmospheric 
Dispersion Factors.'' This proposed new regulatory guide (RG) describes 
an approach for reactor applicants and licensees for determining 
atmospheric relative concentration ([chi]/Q) values in support of 
modeling onsite releases to offsite boundaries from a design-basis 
accident. Also, this proposed guidance implements the methodology in RG 
1.194, ``Atmospheric Relative Concentrations for Control Room 
Radiological Habitability Assessments at Nuclear Power Plants,'' for 
offsite dose locations at boundaries.

DATES: Submit comments by September 16, 2021. Comments received after 
this date will be considered if it is practical to do so, but the NRC 
is able to ensure consideration only for comments received on or before 
this date. Although a time limit is given, comments and suggestions in 
connection with items for inclusion in guides currently being developed 
or improvements in all published guides are encouraged at any time.

II. Additional Information

    The NRC is issuing for public comment a DG in the NRC's 
``Regulatory Guide'' series. This series was developed to describe 
methods that are acceptable to the NRC staff for implementing specific 
parts of the agency's regulations, to explain techniques that the staff 
uses in evaluating specific issues or postulated events, and to 
describe information that the staff needs in its review of applications 
for permits and licenses.
    This DG, identified by its task number, DG-4030, titled, ``Use of 
ARCON Methodology for Calculation of Accident-Related Offsite 
Atmospheric Dispersion Factors,'' is a proposed new RG 4.28 (ADAMS 
Accession No. ML21165A005). This proposed new RG 4.28 provides guidance 
to industry for complying with and implementing the NRC requirements by 
endorsing the use of the ARCON computer code to calculate offsite 
dispersion values out to distances of 1,200 m (3,937 ft) that could 
include the exclusion area boundary and/or low-population zone.
    RG 1.194 (ADAMS Accession No. ML031530505) endorses the use of the 
ARCON96 computer code for calculating accident-related onsite (control 
room and technical support center) atmospheric dispersion values which 
are direct inputs to habitability dose assessments. In addition, RG 
1.145, ``Atmospheric Dispersion Models for Potential Accident 
Consequence Assessments at Nuclear Power Plants'' (ADAMS Accession No. 
ML12216A014), provides the present methodology incorporated into the 
PAVAN computer code, as reviewed by the staff using NUREG-0800 at 
https://www.nrc.gov/reading-rm/doc-collections/nuregs/staff/sr0800/ (ADAMS Accession No. ML070810350), SRP Section 2.3.4 for 
calculating accident-related related, offsite atmospheric dispersion 
values.
    RG 4.28 will provide new guidance for applicants and licensees 
subject to Part 50 of title 10 of the Code of Federal Regulations (10 
CFR), ``Domestic Licensing of Production and Utilization Facilities''; 
10 CFR part 52, ``Licenses, Certifications, and Approvals for Nuclear 
Power Plants''; and 10 CFR part 100, ``Reactor site criteria.''
    The staff is also issuing for public comment a draft regulatory 
analysis (ADAMS Accession No. ML21165A007). The staff develops a 
regulatory analysis to assess the value of issuing or revising a 
regulatory guide as well as alternative courses of action.

III. Backfitting, Forward Fitting, and Issue Finality

    Issuance of DG-4030, if finalized, would not constitute backfitting 
as that term is defined in 10 CFR 50.109, ``Backfitting'' and as 
described in NRC Management Directive (MD) 8.4, ``Management of 
Backfitting, Forward Fitting, Issue Finality, and Information 
Requests''; constitute forward fitting as that term is defined and 
described in MD 8.4; or affect issue finality of any approval issued 
under 10 CFR part 52. As explained in DG-4030, applicants and licensees 
are not required to comply with the positions set forth in DG-4030.
