ical specification surveillance testing, to satisfy monitoring requirements. Such activities could be integrated with, and provide the basis for, the requisite level of monitoring. Consistent with the underlying purposes of the rule, maximum flexibility should be offered to licensees in establishing and modifying their monitoring activities. DG-1336, Page 8 Use of Reliability-Based Programs Licensees are encouraged to consider the use of reliability-based methods for developing the preventive maintenance programs covered under 10 CFR 50.65(a)(2). However, the use of such methods is not required. Applicability of Appendix B to 10 CFR Part 50 With regard to the scope of the Maintenance Rule, as stated in 10 CFR 50.65(b), the NRC understands that balance of plant (BOP) SSCs may have been designed and built with normal industrial quality and may not meet the standards in Appendix B, “Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants,” to 10 CFR Part 50. It is not the intent of the NRC staff to require licensees to generate paperwork to document the basis for the design, fabrication, and construction of BOP equipment (i.e., BOP equipment need not meet the requirements of Appendix B to 10 CFR Part 50). Switchyard Maintenance Activities As noted in Staff Regulatory Guidance Position C.3 of this RG, there may be a need to address maintenance activities that occur in the switchyards that could directly affect plant operations. Plant management should be aware of and have the ability to control these activities. Nonsafety related SSCs that are used in Emergency Operating Procedures Section 8.2.1.3, “Nonsafety-Related SSCs that are used in Emergency Operating Procedures,” of revision 4F to NUMARC 93-01 addresses the question of “Are the nonsafety-related SSCs used in plant Emergency Operating Procedures (EOPs)?” In Revision 4F, two new paragraphs were added to address FSGs. FSGs were developed to provide an extra level of
