I 7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION SACRAMENTO MUNICPAL UTILITY DISTRICT l
DOCKET NO. 50-312 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT TheUnitedStatesNuclearRegulatoryCommission(theCommission)is
-considering the issuance of exemptions from specific requirements in Appendix R
.of.10 CFR Part 50 to Sacramento Municipal Utility District (SMUD, the licensee) for their Rancho Seco Nuclear Generating Station located in Sacramento County, California.
ENVIRONMENTAL ASSESSMENT Identification of the Proposed Action: The exemptions are related to Sections III.G.2, III.G.3, and 111.0 in Appendix R of 10 CFR Part 50, " Fire Protection Program For Nuclear Power Facilities Operating Prior to January 1,1979."
Section III.G of Appendix -R requires fire protection for equipment important to safe shutdown. Such fire protection is achieved by.various combinations of fire barriers, fire suppression systems, fire detectors, and separation of safetytrains(III.G.2)oralternatesafeshutdownequipmentindependentof thefirearea(III.G.3). The objective of this protection is to assure that one train of equipnient needed for hot shutdown would be' undamaged by fire, and that systems needed for cold shutdown could be repaired within-72 hours (III.G.1). Section 111.0 of Appendix R .requ' ires installation of'a Reactor Coolant Pump (RCP) oil collection system capable of collecting and holding the entire lube oil inventory from all four RCP's.
The Need for the Proposed Action: Because it is'not possible to predict the specific conditions under which fire may occur ano propagate, the design basis protective features are specific in the rule rather than the design basis. fire.

PDR ADOCK0500g2 F
Plant-specific features may require protection different from the measures i specified in Sections III.G and 111.0. In such cases, the licensee must demonstrate, by means of a detailed fire hazards analysis, that existing protection in conjunction with proposed modifications will provide a level of safety equivalent to the technical requirements in Sections III.G and 111.0 of .
1 l
Appendix R.
I Environmental Impacts of the Proposed Action: The proposed exemptions' provide a level of safety equivalent to the technical requirements in Sections III.G and 111.0 of Appendix R. These exemptions will not change the types, or allow an increase in the amounts, of effluents that may be reicosed offsite.
Furthermore, these exemptions will not result in an increase in individual or commulative occupational radiation exposure. Therefore, the Commission i
concludes that there are no significant radiological . environmental impacts associated with the proposed Appendix R exemptions.
With regard to potential nonradiological impacts, the proposed exemptions involve features located entirely within the restricted areas as defined in 10 CFR Part 20. They do not affect nonradiological plant effluents and have no other environmental impact. Therefore, the Commission concludes that there are no significant nonradiological environmental impacts' associated with the proposed Appendix R exemptions.
Alternative Use of Resources: This action involves no use of resources not previously considered in the Final Environmental Statement (construction permit and operating license) for Rancho Seco Nuclear Generating Station.
Agencies'and Persons Consulted: The NRC staff reviewed the licensee's request and did not consult other. agencies or persons.

FINDING OF NO SIGNIFICANT IMPACT .
The Commission has determined not to prepare an environmental impact statement for the proposed Appendix R exemptions. l Based upon the foregoing environmental assessment, the Commission !
concludes that the proposed action will not have a significant effect on the quality of the human environment.
