On July 14, 2016, the petitioner requested that the NRC take action with regard to DCPP (ADAMS Accession No. ML16196A294). The petitioner requested the NRC to issue a Demand for Information pursuant to section 2.204 of title 10 of the Code of Federal Regulations (10 CFR), to Pacific Gas and Electric Company (PG&E, the licensee for DCPP) requiring the company to provide the NRC with a written explanation as to why its license amendment request dated June 17, 2015 (ADAMS Package Accession No. ML15176A539), failed to provide complete and accurate information needed by the NRC staff to complete its review and the measures it will implement so as to comply with 10 CFR 50.9, “Completeness and accuracy of information,” in future submittals to the NRC.

As a basis for this request, the petitioner states that the NRC's numerous requests for additional information during the license amendment process constitute prima facie evidence that PG&E violated 10 CFR 50.9 due to the incomplete and inaccurate information in the original license amendment request.

The request is being treated pursuant to 10 CFR 2.206 of the Commission's regulations and has been referred to the Director of the Office of Nuclear Reactor Regulation. The petitioner submitted supplemental information (ADAMS Accession No. ML16215A109) and addressed the Petition Review Board via teleconference on August 2, 2016, to discuss the petition; the transcript of that meeting is an additional supplement to the petition (ADAMS Accession No. ML16232A570). The results of that discussion were considered in the Board's determination regarding the petitioner's request for enforcement action and in establishing the schedule for the review of the petition. The Director determined that the petitioner's request for enforcement action at DCPP met the criteria for review under the 10 CFR 2.206 process. The NRC will take appropriate action on this petition within a reasonable time.
