Appendix 3, a ~ utility has the option of basing the design of the siren notification system on either handbook values for ambient background noise levels, or alternatively on field survey results. Ambient back-ground field survey results were not used for the design criterion.

Therefore, the design criteria is based on the suggested levels in NUREG-0654/ FEMA-REP-1 (Rev. 1), Appendix 3, pages 3-10. -

A preliminary. ambient background field survey was performed September 6, 1986 by ETA, Inc. In one isolated area on the Missouri River, located 4 to 5 miles north of the CNS. The purpose of this was to verify that the siren sound pressure level at this area, while expected to be less than 60 d8(C), is at least 10 dB above the ' ambient sound level. Since conventional special alerting procedures (see Section 2.7) are not capable 'of providing 15 minute notification to this area, CNS opted to verify the ambient background sound level on the river at the 5 mile

,. EPZ.

The results of the ambient background field survey indicate an average ambient sound level (Leg) of 38.3 dB(C) in the 500 Hz octave band.

l Expected siren sound levels at the monitoring site would be at least 52 dB(C) based on the methodology presented in Section 2.4.2. This

! Indicates a difference of 14 dB, which is well above the required 10 dB l

2.7 Special Alerting (FEMA-43 Ref. E.6.2.4) i \

2.7.1 Mobile Alert and Notification Network

.The special alerting components of the CNS Prompt Alert and Notification System are used for those.-areas of the CNS Emergency Planning Zone not covered by fixed sirens or tone alert radios. These areas consist of the Indian Cave State Park in Nebraska, the Brickyard Hill State Wildlife Area in Missouri, and the Missouri ~ River - within the 10 mile

~

EpZ. Appendix C delineates those areas of the CNS Emergency Planning Zone which are to be covered by mobile routes.

Resources, manpower, and vehicles for the CNS PANS will be supplied from existing resources and will be supplemented by mutual aid agreements that are on record for the appropriate state,. county, and local govern-ment emergency response organizations. Appendix H of this report presents maps of the Mobile Alert and Notification Routes and the route activation procedures appilcable for each park.

2.7.2 Alerting Method Rationale As indicated in Appendix 3 of NUREG-0654/ FEMA-REP-1 (Rev.1), it may be more cost effective in sparsely populated areas to use special alerting methods other than sirens. FEMA-43 also indicates that seasonal and diurnal population variations may also be a factor in selecting alterna-tive means of notification. It is most cost effective for the States of Missouri and Nebraska to make optimum use of existing available

resources. Therefore, the respective MO NAP and NE RERP plans for special alerting of the Brickyard Hill State Wildlife Area and the Indian Cave State Park via Mobile Alert and Notification Routes include j the use of onsite Department of Conservation and Park Ranger vehicles with sirens and public address systems. Route dispatching will be accomplished in Missouri by the Conservation Department and in Nebraska I by the Ncmaha County Sheriff. Additionally, trensients on the Missouri l

River will be notified via aircraft with pubile address capability from l

l Kieth Harmon in Tarkio.

The primary purpose of the Mobile Alert and Notification System is to direct the individuals in the parks indoors. The public will be alerted by the broadcasting of either a steady siren blast or a sii,ple message over the mobile public address systems. Signs are posted at park entrances and river landings, and on the river banks at the 10-mile EPZ informing visitors what to do if they hear an alert signal. This message will inform the visitors of an incident, and will_ advise them to tune their radios to KFEQ-AM and KFAB-AM, in Missouri and Nebraska respectively, for further instructions.

2.7.3 Participating Ofganizations The primary and backup responders for each area requiring mobile alert and notification are shown below.

Primary Backup Brickyard Hill Atchison County Atchison County Sheriff Conservation Agent Cox Aviation Other pilots (3)

Indian Cave Park Ranger Assistant Park Ranger Missouri River Kieth Harmon Cox Aviation

[

It should be noted that in both park areas the Conservation Agent and Park Ranger are on the premises. They can commence notification as soon as they are notified. The Cox Aviation aircraft used at Brickyard Hill are located approximately 10 miles from the park. Also, another air-craft is located 1 mile west of Watson, about 5 miles from the park.

The Kleth Harmon aircraft used on the Missouri River is located in Tarkfo, approximately 20 miles from the north end of the river in the EPZ. (The use of Cox Aviation aircraf t is documented in a Letter of Agreement with the SEMA. The - use of the Kieth Harmon aircraft is documented in a letter agreement with M0 SEMA and Kieth Harmon.) An-analysis of the equipment and routes is presented in Appendix H. It is acknowledged that aircraft notification may not be feasible in inclement weather conditions. However, there is little likelihood of transients on the river in poor weather. As stipulated in Appendix 3 of NUREG-0654 FEMA-REP-1 Rev. 1, the areas where aircraft notification is utilized would be reached on a best effort basis.

i CNS 09/86 Missouri River Special Alerting Procedure Summary 1

In the event of an emergency at CNS where notification of visitors on the Missouri River, outside of the siren coverage area, is deemed neces-sary, the following alerting procedures will be followed:

Primary:

1. For a standard sequence of events, Missouri State Emergency Management Civil Defense Agency (H0 SEMA) will notify Kieth Harmon of Tarkio.
2. The pilot will fly over the Missourt River using the stren on a steady blast. Signs at all public landings and access points inform visitors what to do when this signal is given.

Secondary:

3. The pilot will maintain communications with Cox Aviation (flying Brickyard Hill) on the State Sheriff's Network Fre-quency (155.73 MHz), or alternately on the Mutual Aid Fre-quency (154.475 MHz).
4. The pilot will have public address capability to notify transients of evacuation information.
5. Backup to Kleth Harmon of Tarkio is Cox Aviation of Tarkfo, Missouri.

(This map also presents .the Tone Activated Radio Distribution Area, presented' in Section 2.6.1. of this document.) Although there are no areas with a population density greater than 2000 persons per square mile, ,70 J8(C) contours for each siren have also been included. The map is a composite of individual U.S. Geological Survey quadrangle maps with latitude and longitude indications and reproduced to a scale of 1:31680. The map shows the population centers, rivers, and lakes. Individual siren locations are identified and numbered to allow correlation with the individual siren data presented in Appendix 8.

. CNS 07/86 2.4.2 Sound Level Contour Calculation Methodology The 60 d8(C) and 70 d8(C) sound level contour calculations were based upon the method specified in Appendix 3 of NUREG-0654/ FEMA-REP-1 (Rev.1). Sound levels were calculated at sixteen, equally spaced, radial positions around each siren location. The basic calculation procedure, in the absence of interfering topographical features, utiliz-ed Figure 1, of FEMA publication CPG-1-17, to determine the range of the 70 d8(C) sound contour. From this 70 d8(C) contour the sound was atten-usted at the rate of 10 dB per distance doubled. Thus the 60 d8(C) contour was at a range twice that of the 70 d8(C) contour. For ranges between the 60 and 70 d8(C) contours the sound level was calculated by:

SPL (d8) = 70 - 33.3 logto D G

where D = distance from source, ft.

07 o = range of 70 dB contour, ft.

The data obtained from Figure 1 of CPG-1-17 are:

Siren Rating in Range to 70 dB(C) d8(C) at 100 ft. Contour, in ft.

122 4,500 125 5,700 l The effects of topographical features that created shadow zones for a particular siren were determined by subtracting the shielding attenua-tion and distance attenuation from the sound level at the location of the barrier. Thus, in the shadow zone:

SPL = SPL(B) - A, - Ad where SPL(B) = sound level at the barrier, dB A, = shielding attenuation (assuming a rigid straight barrier for sound from a point source), dB l

For those cases where topographical barriers occurred inside the normal  ;

70 d8(C) contour, the sound level at the barrier was calculated as follows:

Siren Rating in Sound Level d8(C) 0 100 ft. in d8(C) l 122 SPL = 122 - 31.45 logto(D/100)

! 125 SPL = 125 - 31.32 logio(D/100). l where D = distance from source, ft.

l l The different constants in the formulas represent slightly different t

attenuation factors, as reflected in Figure 1 of CPG-1-17. Distance ,

attenuation beyond the barrier was calculated on the basis of 10 d8 loss -

I per distance doubled.

The calculation procedure started by reading the terrain contour data f6r each siren from the USGS topographical maps along 16 radials at ,

successive 22.5* increments from due north. Each siren's parameters and the topographical data for each radial were then entered into a computer program which automatically searched each radial for the shadow regions i not in line-of-sight of the siren. The program then calculated a com-plate sound power level (SPL) profile along each radial and found the points where the SPL decreases below 60 and 70 dB, respectively. These l

points were used to generate finsi radial plots of the f0 and 70 d8 l contours for each siren. The contour plots were then viewed along with each radial's SPL profile to visually check that the calculated SPL profile adequately matches the terrain contours.

FOR CNS i

i 1.0 Overview i

During the months of December, 1984 and February, 1985 the 10-mile Emergency Planning Zone (EPZ) was surveyed. The survey included an evaluation of the EPZ with respect to demography and topography, an analysis of the outdoor warning sirens, and an assessment of the tone activated radio distribution. The results of this survey and analysis indicate that the hybrid system consisting of 12 outdoor warning sirens l and over 700 indoor tone activated radios will provide 1005 coverage to the population. This coverage exceeds the current requirements of I

NUREG-0654, Revision 1, by providing prompt 15 minute public warning j from 0 to 10 miles. -

l  :

2.0 Evaluation of Emergency Plannina Zone

( The area within the 10-mile EPZ can best be described as rural farmland with several small towns. The closest population center is Nemaha,

which is about 2.5 miles southwest of the station. The total population of the EPZ is 5636. Table B-1 presents the population centers within l the 10-mile EPZ and their approximate populations, based primarily on l 1980 census data.

The total estimated population in the population centers is 3449, more i

than half of the total EPZ population. Because of the rural character-1stics of the area, the population is relatively stable.

l The Cooper Nuclear Station site is located in Nemaha County, Nebraska,

! on the west bank of the Missouri River. The area within the 10-mile EPZ

consists of a large relatively flat river basin area (mostly farmland)
which extends north and southeast of the site. On both sides of the r
basin the terrain is dominated by rolling hills. The transitions

! between the rolling hills and the river basin are usually very

!' pronounced.

MDiORANDUM FOR: Fran Laden, Assistant Director State of Nebraska Civil Defense FROM: Frank Begley, Division Chief k Natural & Technological Hazards Division

SUBJECT:

Cooper ANS Design Report This is to acknowledge receipt of the material amending the Cooper ANS Design R; port. A copy has been sent to FD4A Headquarters for review.

In the meantime ve have also conducted a review at the regional level.

Tha administrative aspects seem to address the issues as set forth in my memoranda of June 6 and August 19, 1986.

However, recent discussions with Ralph Medina of your staff indicate the po:sibility of using the aircraft perfoming alert on the river' as the means to alert Indian Cave State Park. Please confim your intentions in this r gard and provide us with a draft of the proposed amendment to the Design R: port reflecting this change, prior to COB September 22, 1986. ,
