I. Discussion

    The NRC is issuing a revision to an existing guide in the NRC's 
``Regulatory Guide'' series. This series was developed to describe and 
make available to the public information regarding methods that are 
acceptable to the NRC staff for implementing specific parts of the 
agency's regulations, techniques that the NRC staff uses in evaluating 
specific issues or postulated events, and data that the NRC staff needs 
in its review of applications for permits and licenses.
    Revision 3 of RG 1.142 was issued with a temporary identification 
of Draft Regulatory Guide, DG-1283. This revision (Revision 3) of RG 
1.142 endorses, with certain exceptions, American Concrete Institute 
(ACI) 349-13, ``Code Requirements for Nuclear Safety-Related Concrete 
Structures and Commentary,'' except for Appendix D, ``Anchoring to 
Concrete.'' Appendix D to ACI 349-13 is addressed by RG 1.199, 
``Anchoring Components and Structural Supports in Concrete.''

II. Additional Information

    The NRC published a notice of the availability of DG-1283 in the 
Federal Register on April 23, 2019 (84 FR 16897) for a 60-day public 
comment period. The public comment period closed on June 24, 2019. 
Public comments on DG-1283 and the staff responses to the public 
comments are available under ADAMS under Accession No. ML20141L614.

III. Congressional Review Act

    This RG is a rule as defined in the Congressional Review Act (5 
U.S.C. 801-808). However, the Office of Management and Budget has not 
found it to be a major rule as defined in the Congressional Review Act.

section 50.109, ``Backfitting,'' and as described in NRC Management 
Directive 8.4, ``Management of Backfitting, Forward Fitting, Issue 
Finality, and Information Requests''; constitute forward fitting as 
that term is defined and described in Management Directive 8.4; or 
affect issue finality of any approval issued under 10 CFR part 52, 
``Licenses, Certificates, and Approvals for Nuclear Power Plants.'' As 
explained in this regulatory guide, applicants and licensees are not 
required to comply with the positions set forth in this regulatory
