The NRC is extending the public comment period for DG-1278 from October 31, 2011 to November 11, 2011. This guide endorses Revision 4A to Nuclear Management and Resources Council (NUMARC) 93-01, “Industry Guideline for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants,” which provides methods that are acceptable to the NRC staff for complying with the provisions of Section 50.65, “Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants,” of Title 10 of the Code of Federal Regulations, part 50, “Domestic Licensing of Production and Utilization Facilities.”

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.

On September 6, 2011 (76 FR 55137), the NRC published a notice of issuance and availability of DG-1278. By e-mail dated October 11, 2011, the Nuclear Energy Institute (ADAMS Accession No. ML11286A027) requested an extension of the stated comment period for the purpose of providing sufficient review while attending planned public meetings related to the subject matter of the proposed guide. It is the desire of the NRC to receive comments of a high quality from all stakeholders. Several factors have been considered in granting an extension. The requested comment period extension is reasonable and does not affect NRC deadlines. The additional time will allow stakeholders to discuss the proposed guide during related meetings. Therefore the comment submittal period is extended from the original date of October 31, 2011 to November 11, 2011.
