M EM Your letter of July 1, 1981, requested confirmation that the prompt notification system for Rancho Seco Unit I had been implemented by that date. Previously, on June 30, 1981, the District requested an exemption from the requirements of Section IV.D.3 of Appendix E to 10 CFR 50, since this notification capability does not presently exist. A copy of that letter requesting the exemption is enclosed for your information. Additional information has developed since that time.
i In July, 1981, Wyle Laboratories issued their final report, which incorporated comments from the counties and SMUD's Management Safety Review Committee. Pending acceptance of the report by SMUD's manage-mant, detailed engineering of the prompt notification system will begin.
In anticipation that the system will consist of some mix of sirens and tone alerts, specifications have been prepared for both.
The siren specification has been completed and will be issued for procurement in August. Our schedule now calls for siren delivery in January of 1982, tone equipment delivery in February of 1982, equipment installation in February and March of 1982, equipment testing during April of 1982, and system activation in May of 1982.
Ur.til we are in full compliance with the requirements of 10 CFR 50 Appendix E, Section IV.D.3, actions as described in the Rancho Seco FSAR, Section 12.4.5.7.5.3 and 12.4.5.4.4 are being taken.

SACRAMENTO MUMCIPAL UTILITY DISTRICT C 6201 S Street. Box 15830. Sacramento California 95813; (916) 452-3211 June 30, 1981 DIRECTOR OF NUCLEAR REACTOR REGULATION ATTENTION JOHN F STOLZ CHIEF OPERATING REACTORS BRANCH 4 U S NUCLEAR REGULATORY COMMISSION FASHINGTON DC 20555 DOCKET 50-312 RANCHO SECO NUCLEAR GENERATING STATION UNIT NO 1 TMI ACTION PLAN ITEM III.A.2 On harch 27, 1981, the Sacramento Municipal Utility District requested an exemption from Section (s) (2) of 10 CFR 50.54.
(We erroneously referred to Section (q) (2) in that submittal.) As discussed in that submittal, the District's Emergency Procedures are in effect, however, State and Local plans have not been implemented at this time. We also stated in this submittal that additional require,'nts above those in Appendix E of 10 uFR 50 had been imposed by the State of California and that the local emergency plans could not be implemented until submitted to the State Legislature and approved by statute.
Since thc: time, we have determined that the Emergency Planning Zones required by Federal regulation can be implemented by a local government without State legis-lative approval. Therefore, that exemption is needed only until the implementation of local county plans now expected to occur by the end of this year.
In addition to the exemption requested in our March 27, 1981 letter, the District is hereby requesting an exemption from the requirements of Section IV.D.3 of Appendix E to 10 CFR Part 50.
This requirement states that by July 1, 1981, we should have the capability for notification of the public within the plume exposure pathway within fifteen (15) minutes.
In June of 1980, District staff began soliciting proposals from qualified engineering firms for the design of the Rancho Seco Nuclear Generating Station Early Warning System. By October. 1980, Wyle Laboratories of El Segundo, California, had been selec'e6 Vyle initiated their work with the signing of a contract on Nesn>L.
ti. 1980.
Their scope of work included:
- 1) Obtaining site specific data which could affect system design,
- 2) Designing and siting a siren system for the 10-mile radius,
- 3) Conducting design meetings with the three affected counties l
and the District, and 0

JOHN F STOLZ tege 2 June 30, 1981
- 4) Preparing a final design report which would include the tec.hnical bid specificatiens for the system.
Wyle issued a draft report entitled, " Preliminary Design of Prompt Notification" in January, 1981. Based on comments from the Counties and SMUD's Management Sarety Revice Committee, the Wyle contract scope was modified to specify additional work on alternatives cost / benefit analysis, design and siting criteria, environmental. impact assessment, system maintenance and system activation alternative 3 A final system design was agreed to by all parties in late May, 1981.
Exact siting and purchase / installation specifications were. completed in mid June. A siren equipment purchase request and a California Environ-mental Quality Act Initial Study with Negative Declaration will be issued in early August.
The tene alert. equipment purchase request will be issued by August, 1981.
It is currently anticipated that both the tone alert and siren equipment will be received, installed, and activated by March le 1982.
