SUBJECT:

DAIRYLAND POWER COOPERATIVE LA CROSSE BOILING WATER REACTOR (LACBWR)

PROVISIONAL OPERATING LICENSE NO. DPR-45 EMERGENCY PLAN - EVACUATION TIME ESTIMATE

Reference:

(1)

NRC Letter, Grimes to All Power Reactor Licensees, dated November 29, 1979.

Gentlemen:

Your letter, Reference (1), requested information regarding estimates for evacuation of various areas around nuclear power reactors.

This 12ttr-rcspnnas to that request and includes as an enclosure "LACBWR EVACUATION MAP" - Drawing b/t-300 dated November 6, 1974.

Evacuation time estimates are presented as they relate primarily to the time to implement an evacuation together with the basis for the method chosen.

Notification times and confirmation times are dis-cussed.

Table I, below, lists evacuation time estimates.

Please note that the times presented incorporate the normal 15-ninute notification period.

For clarification, a discussion of notification methods is appropriate.

Each local government's emergency plan, (Vernon County, Wisconsin, Houston County, Minnesota, and Allamakee County, Iowa) use the public radio stations which serve their area as a means of notification to the populace.

Both sheltering and actual evacuation announcements can he given.

The use of local fire station alarms has been considered for additional notification.

The area NOAA station located in La Crosse, Wisconsin can be utilized to augment these notification methods al-though it has limited air time at present.

The ultimate notification method, however, consists of door-to-door contacts due to the dispersed reridences in rural areas.

For this 1815 106

Mr. Darrell G.

Eisenhut, Acting Directar LAC-6770 Division of Operating Reactors January 31, 1980 reason the local emergency government plans address the use of key neighborhood contacts and squad car patrols with public address system announcements.

Notification estimates are therefore assumed to be well within the required 15-minute time frame during the normal wakinq hours (6:00 a.m.

to 10:00 p.m.) for most of the popalation.

In addition, the populace residing within approximately one or two miles of each population center which has a fire station will have an alert within the 15-minute time range 24-hours a day.

The use of key telephone contacts, public address squad cars, and door-to-door notifications ensure complete area coverage within one hour regardless of weather conditions or time of day.

TABLE I Distance & Sectors Best Estimate Adverse Estimate Confirmation 2 Miles, Cast 30 Minutes 60 Minutes 60 M nutes Sector 2 Miles, West No permanent residents in the area.

All Sector transients in Upper Mississippi Wildlife Refuge can hear site siren within 2 miles of plant.

5 Miles, NE 30 Minutes 60 Minutes 60 Minutes Sector 5 Miles, SE 45 Minutes 90 Minutes 60 Minutes Sector 5 Miles, NW 45 Minutes 90 Minutes 60 Minutes Sector 5 Miles, SW 45 Minutes 90 Minutes 60 Minutes Sector 10 Miles, NE 120 Minutes 180 Minutes 120 Minuten Sector 10 Miles, SE 120 Minutes 240 Minutes 90 Minutes Sector 10 Miles, NU 120 Minutes 240 Minutes 120 Minutes Sector 10 Miles, SW 120 Minutes 240 Minutes 120 Minutes Sector 1875 107,

Mr. Darrell G.

Eisenhut, Acting Director LAC-6770 Division of Operating Reactors January 31, 1980 Confirmation time will normally be shortened by use of neighborhood musters at the congregate care facilities and phone calls to the missing person residence.

The times listed in Table I assume vehicles travelling door-to-door to check.

The basis for the notification methods chosen are described as follows:

In each case, as presented in Table I, time estimates are based on discussions held with local law enforcement officials and civil defense coordinators.

Estimates are based on actual experiences in recent past history such as tornado warnings in the summer of 1978, flash ficods during most springs and the summer of 1979, and prior drills.

Paved and well maintained state and federal highways traverse each sector of the Emergency Planning Zone (EPZ) with sufficient capacity to evacuate the entire area which is lowly populated.

Private vehicles are assumed to handle the major transporation needs.

Con-sideration is given to alternate mass transport modes in the local emergency government (i.e.,

civil defense) response plans.

The largest population center within the 10-mile EPZ is the Village of Stoddard, Wisconsin, approximately 0 miles north of the plant site on Wisconsin State Highway 35.

This village has a population of approximately 900 people and the entire EPZ contains less than 7000 individuals.

There are no special facilities (hospitals, nursing homes, boarding schools, etc.) within the EPZ.

Each local official who has control over an EPZ area identified in this response has participated in a discussion with a key member of the plant staff regarding the contents of this letter and each person concurs with its contents.

Concurrence documentation is on file at the site.

If there are any questions concerning this response, please contact us.

Very truly yours, DAIRYLAND POWER COOPERATIVE
