Notice is hereby given that the Director, Office of Nuclear Reactor Regulation, has issued a director's decision (ADAMS Accession No. ML17108A590) on a petition filed by the petitioner on July 14, 2016 (ADAMS Accession No. ML16196A294). The petition was supplemented by an email dated August 2, 2016, and a letter dated March 27, 2017 (ADAMS Start Printed Page 23319Accession Nos. ML16215A109 and ML17102A524, respectively).

The petitioner requested that the NRC take enforcement action against PG&E related to the DCPP. Specifically, the petitioner requested that the NRC “issue a Demand for Information pursuant to 10 CFR [title 10 of the Code of Federal Regulations] 2.204 to PG&E requiring the company to provide the NRC with a written explanation as to why its June 17, 2015, license amendment request failed to include all the accurate information needed by the NRC staff to complete its review and the measures it will implement so as to comply with the 10 CFR 50.9 [“Completeness and accuracy of information”] in future submittals to the NRC.”

On August 2, 2016, the petitioner met with the NRC's Petition Review Board. The meeting provided the petitioner and the licensee an opportunity to provide additional information and to clarify issues cited in the petition. The transcript for that meeting is available in ADAMS under Accession No. ML16232A570.

The NRC sent a copy of the proposed director's decision to the petitioner and the licensee for comment on March 15, 2017. The petitioner and the licensee were asked to provide comments by March 29, 2017, on any part of the proposed director's decision that was considered to be erroneous or any issues in the petition that were not addressed. While most of the comments received from the petitioner are outside the scope of the 2.206 petition, the comments are addressed at the end of the final director's decision.

The Director, Office of Nuclear Reactor Regulation, has determined that the request for enforcement action against PG&E be denied. The reasons for this decision are explained in the director's decision DD-17-03 pursuant to 10 CFR 2.206 of the Commission's regulations.

The NRC will file a copy of the director's decision with the Secretary of the Commission for the Commission's review in accordance with 10 CFR 2.206. As provided by this regulation, the director's decision will constitute the final action of the Commission 25 days after the date of the decision unless the Commission, on its own motion, institutes a review of the director's decision in that time.
