/E ~><E Op/
Attention:
Mr. J.
D. Shiffer, Vice President Nuclear Power Generation Gentlemen:
Enclosed is a copy of the FEMA Region IX report titled "Diablo Canyon Power Plant Site-Specific Offsite Radiological Emergency Preparedness Alert and Notification System equality Assurance Verification."
The transmitting November 7, 1984 letter from FEMA to the NRC (copy also enclosed) states that
FEMA has determined that the prompt, alert and notification system...meets the specific design requirements of NUREG-0654/FEMA-REP-1, Rev.
1, and 'FEMA-43."
It is our conclusion that, based on this report, there is a means for notifying and providing prompt instructions to the public within the plume exposure pathway Emergency Planning Zone around the Diablo Canyon Power Plant.
Sincerely, F. A.
enslawski, Chief Emergency Preparedness and Radiological Protection Branch

DIABLO CANYON POWER PLANT SITE-SPECIFIC OFFSITE RADIOLOGICAL EMERGENCY PREPAREDNESS ALERT AND NOTIFICATION SYSTEM
,. QUALITY ASSURANCE VERIFICATION State Of California San Luis Obispo County I.
INTRODUCTION A.
The Diablo Canyon Power Plant, operated by Pacific Gas and Electric Company, consists of two reactor units.
Unit 1 is a 1084 MWe (net)
Westinghouse pressurized water reactor and was licensed by the Nuclear Regulatory Commission for full-power operation in 'late July 1984.
- However, a court order issued in August 1984 placed a stay of operation on the license pending a review hearing that is scheduled for November 1984.
Unit 2 is a 1106 MWe (net)
Westinghouse pressurized water reactor scheduled for completion in the summer of 1985.1 The Diablo Canyon Power Plant site consists of approximately 750 acres located near the mouth of Diablo Creek approximately 12 miles southwest of the City of San Luis Obispo, California, which is the county seat.
The land adj.acent to the Diablo Canyon site is predominately hilly, with numerous canyons and ravines, and is bordered on the west by the Pacific Ocean.

ove The State of California Office of Emergency Services has adopted San Luis Obispo County's recommendations in establishing the official state extended and basic emergency planning zones for the Diablo Canyon Power Plant.
The extended emergency planning zone (EEPZ) encloses a boundary of approximately a 20-mile
- radius, extending 35 miles southeast of the Diablo Canyon Power Plant to include Nipoma Beach.
Within this
- EEPZ, a basic emergency planning zone (BEPZ) encloses a boundary with a minimum radius of 10 miles from the Diablo Canyon Power Plant, extending approximately 20 miles southeast of the plant to include Pismo Beach, Grover City, Oceana, and Arroyo Grande.
The EEPZ also extends approximately 18 miles north of the plant to include Cayucos.
The federally recognized EPZ is defined by a 10-mile-radius circle with the Diablo Canyon Power Plant as the center point.
Approximately one-half of the 10-mile EPZ (on the southwest portion of the circle) is over the Pacific Ocean.
In order for San Luis Obispo County to provide for detailed planning and implementation of protective
- measures, 15 protective action zones (PAZs) have been established.
PAZs 13, 14, and 15 are in the EEPZ; PAZs 1 through 12 are in the BEPZ.
The 10-mile EPZ encompasses PAZs 1 through 5 and small portions of PAZs 8 and 9.
The majority of the population is located in the north and southeast sections of the Diablo Canyon Power Plant 10-mile EPZ.
The primary local
q K-giI
government jurisdiction within the Diablo Canyon Power Plant 10-mile EPZ is San Luis Obispo County, which includes the communities of Morro Bay, Avila
- Beach, Baywood Park, Cuesta-by-the-Sea, and Los Osos.
The City of Morro Bay had a 1980 population of 9064 persons.2 According to 1980 census figuresf it is estimated that the population within the 10-mile EPZ is approximately 18,000 residents.

The physical means established for alerting the public within the Diablo Canyon Power Plant 10-mile EPZ is documented in the following reports that are included as appendices to the Design Report:
Pacific Gas and Electric Company, "Early Warning Siren System Test Report at Diablo Canyon Power Plant," October 1, 1982; and Pacific Gas and Electric Company, "Early Warning Siren System Test Report at Diablo Canyon Power Plant,"
1983.
FEMA Region IX and the Regional Assistance Committee (RAC) have evaluated three offsite emergency preparedness exercises for the Diablo Canyon Power Plant:

FINDINGS FOR EVALUATION CRITERION E.6 The Design Report describing the alert and notification system for the Diablo Canyon Power Plant was reviewed against evaluation criterion E.6 and Appendix 3 of NUREG-0654/FEMA-REP-l, Rev. 1, "Criteria for Preparation and Evaluation of Radiological Emergency
Response
Plans and Preparedness in Support of Nuclear Power Plants"
'(hereinafter referred to as NUREG-0654/FEMA-REP-1<
Rev.
1).
This evaluation criterion states:
Each organization shall establish administrative and physical
- means, and the time required for notifying and providing prompt instructions to the public within the plume exposure pathway Emergency Planning Zone.
(See Appendix 3.)
It shall be the licensee's responsibility to demonstrate that such means exist, regardless of who implements this requirement.
It shall be the responsibility of the State and lo~al governments to activate such a system.
The bases for review against this evaluation criterion were the corresponding acceptance criteria of FEMA-43, "Standard Guide for the Evaluation of Alert and Notification Systems for Nuclear Power Plants"10 (hereinafter referred to as FEMA-43).
This quality assurance verification review was performed to make a determination of alert and notification system adequacy prior to conducting a demonstration of this system at the Diablo Canyon Power Plant on August ll, 1984.
Based upon this quality assurance verification review and public survey results, International Energy Associates Limited concludes that the design and implementation of the alert and notification system for the Diablo Canyon Power Plant and its supporting procedures conform sufficiently to the acceptance
- criteria, as stated in FEMA-43, for evaluation criterion E.6 of NUREG-0654/FEMA-REP-1, Rev.
1, to support a
FEMA finding that the alert and notification system is adequate.
fe
P This portion of the quality assurance verification review discusses the Diablo Canyon Power Plant alert and notification system design against FEMA-43 acceptance criteria in the following areas:
the administrative means of alerting, the physical means of alerting, and the special alerting methods (utilization of institutional alerting systems)
A.
d
' at'E.6 lg FEMA-43)
The Design Report addresses those individuals within the Pacific Gas and Electric organization who are responsible for recommending alert and notification system activation to the local governments.
The Design Report also specifies county government officials who are responsible for alert and notification system activation.
After reviewing the aforementioned documents (references 3, 4, and
- 5) dealing with emergency procedures for Diablo Canyon Power Plant, the decision logic was developed as shown in Figure 1 of this report.
As Figure 1 indicates, the procedures, as reflected in the aforementioned emergency planning documentation, satisfy the acceptance criteria of FEMA-43.
The decision to activate the sirens is made by the Emergency Services Director at the San Luis Obispo County Emergency Operations Center (EOC).
Subsequently, the Emergency Services Director contacts the Sheriff's Watch Commander, who is responsible for physically activating the sirens, and the Public Information Officer, who is responsible for alerting the Emergency Broadcast -System (EBS) stations.
The Public Information Officer prepares the EBS messages
- that, upon authorization from the Emergency Services Director, are transmitted via a
