I. INTRODUCTION This document describes the Early Marning System for the Mashington Public Power Supply System's Nuclear Plants 1 and 2 Ten-Mile Emergency Planning Zone. The Early Marning System will be utilized as described in the Mashington Public Power Supply System's MNP-1 and 2 Emergency Preparedness Plan.
The early warning system is based on a study performed by the Supply I
System using the CRAG II computer code and probabalistic analysis methods to assess the risk and benefit. The study is titled, "Asses'sment of Emergency Early Marning at Mashington Public Power Supply System Hanford Site", and is dated October 1982.~ ~
Due to the plants being located on the Hanford Reservation, the popula-tion is extremely low within the 10 mile zone. Mith this low population, the study demonstrated that effective notification within the Emergency J Planning Zone could be performed by a combination of Emergency Broadcast System radios, U.S. Coastguard clearing the Columbia River, Benton County Sheriff clearing the Yakima River, and two sirens located within five miles of the plant on the Columbia River.
This early warning system described herein has already been submitted, reviewed and approved by the NRC.~ ~ >

II. WASHINGTON NUCLEAR PROJECTS 1 AND 2 EMERGENCY PLANNING ZONE POPULATION The Washington Public Power Supply System leases 1089 acres of land on the Hanford Reservation, located north of Richland, Washington, and con-trolled by the Department of Energy. The reservation covers an area of approximately 570 square miles, consisting mostly of semi-arid land. The land leased by the Supply System is approximately 3 miles west of the Columbia River and 12 miles north of the populated area of Richland.
o Population Estimates Figure 1 is a map of the Ten-htile Emergency Planning Zone.~ ~
This Ten-thile Emergency Planning Zone is the area for which the Early Warning System has been designed to cover.
Figure 2 presents the compass sector population estimates for 1984.
Estimates were made relative to the center of the triangle formed by the three reactors. These figures were taken from the MNP-2 Envi-ronmental Report~ ~
Operating Li'cense stages, Amendment 85 where references and bases are given. These figures have been revised to reflect current values and obtained from a population survey con-ducted by Benton County. The transient industrial workers on the Hanford site have been updated by the appropriate facilities.
o Permanent Residents Permanent residents included all people residing in the area but excluded occupants of institutions. The ten-mile radius around the site is shown in Figure l. In 1984, an estimated 2,147 people were living within the Ten-Mile Emergency Planning Zone. The nearest inhabitants occupy farms which are located east of the Columbia River and are thinly spread over five compass sectors. There are no permanent residents located within three miles of the site. Only about 90 persons reside between the three-mile and the five-mile radii; these are all located east of the Columbia River.

Of the 2,147 people residing in the 10-ttile EPZ, about 1,718 live in Franklin County and about 429 in Benton County. None of the resi-dents live in incorporated cities.
There are no significant changes in land use expected in Franklin County over the next several years and, as it is currently irrigated to about the maximum amount practicable, little population increase is foreseen. No significant change in land use on the Hanford Reservation is expected, and no foreseeable population will reside there; however, the'nincorporated area near the Horn Rapids 0am on the Yakima River in the SSW sector is expected to be the primary growth area within the 10-Mile EPZ. Population growth within this area is projected to be about six percent per annum.
o Transient Popul ations The transient population is divided into three main subgroups:
- 1) industrial employees, 2) migratory agricultural, workers, and
- 3) sportsmen. Figure 3 illustrates this population location graphically.
Industrial employees in the Ten-Nile EPZ total 8,648. Most of the employees will be located in Benton County and will form the main population to be evacuated, outnumbering the permanent residents by about 4:1.
About one-tenth of the industrial employees will work at MNP-1, MNP-2, MNP-4 and at the Plant Support Facility. The projected size of this work force (approximately 1,000) varies considerably with time; as many as 12,000 workers were employed in June 1981 prior to the slowdown of construction at MNP-1 and the termination of MNP-4, but the-figure in September 1982 was down to nearly 5,000.

Therefore, the industrial planning figure of 8,648 to be evacuated is conservative.
There are up to approximately 3,346 migratory farm workers in the Ten-Mile Emergency Planning Zone. This figure may be high due to the possibility of double counting during the different harvest periods. The peak season for these workers is May and June; the next highest employment season is during the fall harvest. These workers consist of both permanent and temporary residents of the Tri-Cities area, some living within the Ten-Nile Emergency Planning Zone. The numbers shown on Figure 3 reflect their work locations in Franklin County within the Ten-Mile Emergency Planning Zone, not their residences.
Sportsmen, consisting of hunters, fishermen, and boaters, enjoy activities mainly along the east bank of the Columbia River. The primary fishing season is. from June thr ough Hovember; the main hunt-ing season being October through January. The heaviest use of the area by sportsmen is on weekends and holidays in the early morning hours. On the average, 50 fishermen and 10 hunters are present in
Oy y

)
Franklin County during the weekdays. This increases to about, .
100 fishermen and 50 hunters on weekends and holidays. Sportsmen also use the Yakima River, with an estimated maximum of 50 at any time in this area. Ouring peak fishing or hunting times, up to 1,050 sportsmen may be located within the Ten-Mile Emergency Planning Zone.
The main concentration of sportsmen consists of fishermen located just south of the Ringold Fish Hatchery spillway on 'the Franklin County side of the Columbia River. Hunting consists of both water-fowl (hunted at the Wahluke Hunting Area on the Franklin County side of the Columbia River) and upland game birds (hunted inland on the 4
farmland of Franklin County). Four hundred sportsmen may be located
")~ around the Ringold Fish Hatchery and the Wahluke Hunting Area an'd the rest distributed inland. Of these, 1,000 are assigned to Franklin County and 50'to Benton County. An additional recreation attraction has been created in the south section of the~Ten-Mile Emergency Planning Zone in Benton County. An off-road vehicle -park has been developed, as many as 500 participants/spectators may be present during an event.
o S ecial Po ulation There are no individuals within the Ten-Mile Emergency Planning Zone confined to institutions such as hospitals, nursing homes, or penal institutions. There are three schools, the Edwin Markham Elementary School, the Cypress Gardens School and the County Christian Center, with a total enrollment of approximately 365 students and staff.
Although most of these students live within the Ten-Mile Emergency Planning Zone, the total amount was added to the population for this study.

III. EARLY WARNING NOTIFICATION PROCESS The approach taken by the Supply System in designing the Early Warning System for the Washington Public Power Supply System's Nuclear Pro-jects 1 and 2 is based on a study(") and correspondence(
submitted to the Nuclear Regulatory Commission (NRC) and approved as meeting the intent of the NRC requirements.(1 )
The emergency shall be classified by the Plant Emergency Director as soon as an off-normal event occurs that corresponds to one of the initiating conditions. Each class is defined in such a manner so that emergencies can be classified either up or down, depending on whether the emergency becomes more or less severe. When there is doubt as to the classifica-tion of the emergency, the more conservative class shall be used. After classifying the emergency, the Plant Emergency Director will initiate notification of emergency personnel. The extent of the notification will depend upon the emergency classification.
Initial emergency notification to nearby Supply System plants, the State, County, and the Department of Energy will be made through the Security Communications Center. Both phone lines and radio communications are available. The nearby facilities will implement the necessary emergency actions. In the event of an emergency requiring protective measures to be taken at the nearby facilities, the Recovery Manager at the Emergency Operations Facility or the Plant Emergency Director will give specific instructions.
Notification of the County Emergency Dispatch Center and Benton County Emergency Management in Kennewick, Department of Energy, and the Washington State Department of Emergency Management (State Emergency Operations Center) will be by dedicated phone lines. Notification to the Nuclear Regulatory Commission in Bethesda, Maryland, will be made via the NRC dedicated phone network from the Control Room. The Nuclear Regula-tory Commission offices in Bethesda will patch the call through to the
~0 'I I J'p Y

% II
'I
~0 a,
Nuclear Regulatory Commission offices in Region V, Walnut Creek, California. Notification of all other offsite emergency agencies will be made hy telephone. Radio provides backup communications to the County Emergency Dispatch Center and Department of Energy-RL.
Activation of the Early Marning system is the responsibility of the Benton/Franklin Counties Department of Emergency Management Director.
The Early Marning System is designed to provide both an alert signal and information to the population on an area-wide basis throughout the Ten-Mile Emergency Planning Zone. Two means have been established by the Supply System for notification of the public. For residents within the Ten-Mile Emergency Planning Zone the tone activated radios provide the
'rimary means of notification. These radios. are activated by the Emer-gency Broadcast System signal and provide instructions for protective actions. The system is designed to be operable within 15 minutes of a decision to activate the system.
Notification of transient population along the Columbia and Yakima rivers is provided by the Coast Guard and by local law enforcement agencies, respectively. Two sirens are located along a segment of the Columbia River to help expedite Coast Guard evacuation of the river (Figure 4).
Activation of the sirens should reduce the need for Coast Guard person-to-person interactions along the Columbia River upstream from the MNP-2 pump house for about two (2) miles. This 'is -the segment of the river that is most utilized by the public. It is estimated that notification of transients along the Columbia River can be accomplished within three (3) hours.
Notification of transients along the Yakima River is the responsibility of the Benton County Sheriff. Through cooperative agreements under emergency conditions, the Sheriff can call. upon other law enforcement authorities to perform various tasks. Primary use areas of the Yakima River are adjacent to Highway 240. Users will be informed as a peri-pheral task in the process of controlling use of State Highway 240, which will be done hy the law enforcement officers in the vicinity at the time
OO I I g I ~$ '~1 I I' ft II
However, it is likely that =people not initially alerted by the siren signals or the tone-activated radios will eventually be alerted by TV, radios (not of the tone-activated type), and other informal means, including telephone calls from neighbors, friends, relatives, and word-of-mouth. In addition, the initial activation of the Early Marning System would be followed by subsequent activations to ensu're that the total population was alerted.
In conclusion, this report describes an early warning system and process which provides effective early notification,to population groups located within the 10 mile Emergency Planning 2one and which is consistent with commitments set forth in our previous submittals to the Nuclear Regula-tory Commission.~ ~
The technical basis for the adequacy of the system is. documented in a report entitled "Assessment of Early Marning at Mashington Public Power Supply System Hanford Site, R.F. Haight, October, 1982.~ Utilization of this early warning approach was previously approved by the Nuclear Regulatory Commission, February 14, 1983.~

Mhen the receivers are not used for receiving emergency information, they may be used to receive the normal KONA programming. Receivers used in this way provide items of considerable day-to-day value to residents, being, in effect, a free radio with one channel of program material.
When the programmed. material can be received 'at any time, the resident is also reassured that his receiver is in good working order. The need for frequent testing is thereby eliminated, minimizing annoyance and anxiety to residents.
Distribution of the tone-activated radios is conducted through a coordi-nated effort between the Benton and Franklin County Department of Emergency Management and the Supply System.
In order to maintain a thorough and complete coverage of the area, various approaches are being used by the Supply System and the Benton County Department of Emergency Management to keep up-to-date records of persons moving into the Ten-Mile Emergency Planning Zone. These are:
o Public Utility Districts o Post Office route carriers o County Auditors o Recanvassing of the area The primary method will be through the Public Utility Districts and the Post Offices. The alternate approach .will be through the County Audi-tor's Office or, if need be, recanvassing the area. An additional mechanism is the mail returns of a quarterly information newsletter sent to all residents within the 10-mile Emergency Planning Zone. The returned newsletter is an indication of a resident's change.

V. COAST GUARD RESPONSE The United States Coast Guard maintains river control capability at the City of Kennewick. Agreements and procedures are in place for closing and clearing the river of recreationists. The Department of Energy jet boats are available to assist. Automatic closure of the Columbia River occurs during a General Emergency classification. All other closures are at the request of the Supply System's Recovery Manager. River closure boundaries are from the Old Hanford Townsite to the north to Leslie Groves Park to the south. Arrangements have been made with Benton County Sheriff to transport a Coast Guard representative to the Old Hanford Townsite to meet the Department of Energy boat and an environmental monitor. A Supply System or Washington State environmental monitor will meet the Coast Guard boat at Leslie Groves Park.
VI. SIREN SYSTEM DESCRIPTION The siren system consists of three pole mounted, 122 db, electronic, omnidirectional sirens. Siren locations and estimated coverage is shown on Figure 4. Each uni is battery powered with solar cells or AC power, that is used to keep the batteries at full charge. Initial experience resulted in cold weather failures. Corrective actions are being imple-mented to assure operability. In addition, each sirens'atteries are capable of being recharged by external vehicular chargers, if necessary.
All electronics, power and control equipment is housed within a weather-proof, pole mounted steel enclosure. The sirens and their associated equipment mount to Class II cedar poles designed to withstand wind load-ing in excess of 100 mph. The poles are guyed and the area at the base of the pole is graveled for fire protection. Each siren has an appropri-ate sign warning of the danger of its high sound levels.
The siren control system is a Remote Data Acquisition/Control System that is used for transmitting alarm or status messages between the master sta-tion and remote stations. The system uses UHF radio as the communica-tions link. The Data Acquisition/Control System consists of a master station and remote status and control units as follows:
