e UNITED STATES NUCLEAR REGULATORY COMMISSION SACRAMENTO MUNICIPAL UTILITY DISTRICT i
DOCKET NO. 50-312 ENVIRONMENTAL ASSESSMENT AND F1NDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (The Commission) is considering i.
issuance of an exemption from the requirements of 10 CFR Part 20, Appendix A, footnote d-2(c), to the Sacramento Municipal Utility District, who holds Facility Operating License No. DPR-54, which authorizes operation of the Rancho Seco Nuclear Generating Station.. Rancho Seco is a pressurized water reactor located in decramento County, California.
ENVIRONMENTAL ASSESSMENT Identification of the Proposed Action:
The exemption from 10 CFR Part 20 would allow the use of a radiciodi.ne protection factor of 50 for Mine Safety Appliances (MSA) GMR-I canisters at Rancho Seco.
The Need for the Proposed Action: The exemption is needed to facilitate refueling operations at Rancho Seco by reducing the time and person-rem exposure required to complete tasks that require respiratory protection.
' Environmental Impacts of the Proposed Action: There are no environmental impacts of-the proposed action. The proposed exemption involves a change in the installation or use of the facility's components located within the restricted areas as defined in 10 CFR Part 20. The staff has determined that the proposed exemption involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupation radiation exposure.

[..a With regard to potential non-radiological impacts, the proposed exemption involves systems located entirely within the restricted areas as defined in
It does not affect non-radiological plant effluents and has
.no other environmental-impact. Therefore, the Commission concludes that there are no si'gnificant non-radiological environmental impacts associated with the propesed exemption.
Alternative to the Proposed Action: We have concluded that there is no measurable environmental impact associated with the proposed exemption. The principal alternative would be to deny the requested exemption. This would not reduce environmental impacts of plant operation.
' Alternative Use of Resources: This action does not involve the use of resources not previously considered in the Final Environmental Statement toperating license) for Rancho Seco Nuclear Generating Station.
Agencies and Persons Consulted: The NRC staff reviewed the licensee's request and did not consu'lt other agencies or persons.
FINDINGS OF NO SIGNIFICANT IMPACT The Comission has determined not to prepare an environmental impact statement for the proposed exemption.
Based upon the foregoing environmental assessment, we conclude that the proposed action will not have a significant effect on the quality of the human environment.
For further details with respect to this action, see the request for exemption dated November 17, 1988, which is available for public inspection at
