1.0 INTRODUCTION
A prompt clerting system consisting of 40 sirens (39 new and one existing) has been installed within the 10-mile Emergency Planning Zone (EPZ) of the San Onofre Nuclear Generating Station (SONGS). The system is deployed throughout community, beach front, military, and commercial crecs in poris of Orange and San Diego Counties. The system is divided into five zones with control and activation retained by five agencies; namely:

2.0 TEST PLAN DESCRIPTIONS The following series of tests were conducted and data obtained which portray the characteristics of the siren system. Detailed descriptions of the tests are contained in subsequent subsections.
Acceptance Tests The acoustic output (sound level at 100 f t on axis) and the maximum sound level on the ground in the vicinity of the siren mounting pole were measured.
Range Tests Tests were performed on 10 sirens (three each with nominal sound level ratings of 107 dB(C), ll2 dB(C) and ll5 dB(C), and one with a nominal rating of 125 dB(C)) to verify that siren sound levels at distances out to the design range would equal or exceed expectations. Measurements were made in three directions close to the design range and at three intermediate locations in one direction.
Zone Tests Measurements were made curing the simultaneous activation of all sirens within each zone. Sixty-five measurement locations were selected at random and supplemented by 16 extra sites to determine siren sound levels throughout the community.. Observers stood by all sirens during these tests to document each siren's operation.
Community Response Tests The complete siren system was activated.
Acoustic measurements were made at 10 locations selected from the zone test sites. Observers stood by the 34 community sirens for this test to verify their proper operation. The full-scale test wns immediately followed by a telephone survey of local residents and a face-to-f oce interview of visitors in public areas.
These surveys were performed to determine where the siren test was audible within the EPZ.
Personnel and Instrumentation Acoustic measurements were performed by 27 engineering personnel. For all tests, acoustic measurements were obtained by means of instrumentation complying with American National Standard ANSI S t.4-1971 (R l 976),

I Specifications for Type 2 Sound Level Meters. Where onolog recordings of sound pressure time histories were obtained for subsequent analysis, nnd where such recordings were substitutes for the direct reading of sound level meters, the recording system (including microphone and accessories) met the requirements of ANSI S6.l-1973," Qualifying a Sound Data Acquistion System."
Eoch item or system of measurement equipment was calibrated in accordance with the manuf acturer's specifications. Field calibrations wer: performed prior to and of fer each test sequence by means of an acoustic calibrator. All analog and digital recordings of sound pressure were preceded by an acoustic calibration signal identical to that used for field calibration of measurement equipment.
2.1 Acceptance Tests Measurements were mode in three directions from the siren, approximately 120 apart at a distance of 100 f t from the siren and at a height of 35 f t, close to the some elevation as the siren. At two of the three locations, data were recorded on analog tape.
At the third position, sound levels were measured using o calibrated Type I sound level meter using on extension cable to allow the I
microphones to be placed atop the pole and leave the meter close to the ground.
The siren was activated af ter the recorder and sound level meter microphone systems were set up, calibrated and the recorder turned on. The siren was allowed to achieve a steady state operating condition and run in this condition for a period I
of of least I minute and turned off before the onolog tape recording was stopped.
An activation time of of least 30 seconds was required for this measurement in order to simultaneously measure the maximum siren sound level. A sufficient recording time before and af ter the siren test was employed to determine the bockground ambient noise level close to the time of the test.
The siren fundamental frequency was identified through a spectrum analysis of the analog tape-recorded signal taken from the steady state portion of the recorded signol. This analysis was made using a narrow band spectrum anolyzer.
Measurements were made at 10 f t intervals along a radial line from the pole to determine the maximum siren sound level to which the public might be exposed.
These data were examined to determine the position of which the maximum level occurred.
I 2-2 i
All siren sound levels, both occeptance and maximum level, were determined in terms of the C-weighted sound level. The sound level meter wc. set to a slow time constant to assure that measured levels represented the overage value of the signol.
2.2 Siren Acoustic Rmge Tests The ocoustic range for 10 sirens was determined. Three somptes of each of the three types of new sirens (ll5 dB(C), ll2 dB(C), and 107 dB(C)) employed were measured and, in addition, the acoustic performance of the existing 125 dB(C) siren was documented in these tests.
For each siren tested, an array of three radial lines was established, wherever possible, according to the following rationale:
a.
One line was selected in the direction close to the maximum population density near the siren site.
b.
One line was selected in the direction of worst propagation conditions (i.e., towards natural or artificial barriers or through heavy ground cover).
c.
The lost radial line was selected in any convenient intermediate dir.ection, prefercbly coinciding with one of the directions employed for the 100 f r measurements.
Along each of these radial lines a measurement position was selected which was os close os possible to the position of the estimated siren design range in that direction. This corresponds to the position where the siren level is expected to equal the design value (for details on system design procedures, see Appendix A i
under Siren Design Range). The design level was 60 dB(C)in most residential creas, 65 dB(C) near the beach, and 70 dB(C) in high ambient noise level creas near
(
freeways or urban centers.
In addition, three supplemental measurement positions were selected at
(
intermediate positions along one radial line.
Data from these intermediate positions were expected to aid in determining each siren's signal propagation characteristics. Range test measurements were made at the some time accep-j tonce tests were performed, thus minimizing multiple siren activations. For the W Y L E L A B O R AT O R I E S
A range tests, most data were measured with sound level meters set to on A-weighting in order to minimize the anomalous effects of wind noise.
Such A-weighted levels were subsequently converted to C-weighted siren sound levels. At selected locations, broadband data were recorded on magnetic tape and subse-quently analyzed in the laboratory.
2.3 Zone Tests A complete acoustic test of all sirens within each of the five zones was conducted to establish that the siren system provides the expected siren sound levels throughout the community.
1 For each of the five zones a uniform rectangular grid with a grid spacing of 1,000 f t was overlaid on a map. The zone boundaries were marked on the overlay ad the expected 80 dB(C) siren sound level boundary was identified. All grid points between these two boundaries were then examined and any points corre-spcm.."m to on area that is normally inaccessible or uninhabited were discarded.
The remaining grid points were then numbered in a serpentine sequence.
A rondom sample of these grid point numbers were then drawn, one at a time, using a random number table, until a sample size representing approximately 20 percent of the total numbered grid points was drawn. These selected grid points then became the measurement positions for the zone acoustic tests. Measurements were mode at a total of 81 locations throughout the five ocoustic test zones.
The measurement procedures employed in the siren ranging tests were also employed for the zone tests. That is, measurements were made of the A-weighted siren sound level and ambient background level. These daic were converted to ctave band ambient sound level (see obtain the C-weighted siren level and the L90 Appendix A for definitions).
2.4 Commmity Response Tests A full-scale activation of the siren system was conducted and acoustic measurements were made at 10 locations throughout the EPZ.
Immediately following the test, a telephone survey of 529 residents was performed to determine the cierting effectiveness of the siren system. The sampling plan was designed to insure, with a 95% confidence level, that a survey sample greater than 400 residents would result in a sample error less than 5%. Also, directly following the test, a face-to-foce survey of 135 persons occupying shopping areas and outside recreation areas was conducted.

3.0 TEST RESULTS This section presents dato obtained during the tests of the San Onofre prompt olerting system which were conducted during the week of January 25 to 29,1982.
3.1 Siren Acceptece Tests Table I contains a compilation of siren chorocteristics derived from the manuf acturers' dato and obtained during the siren tests. These dato illustrate pertinent information relative to the electrical power input requirements of the sirens and their ocoustic output chorocteristics.
Toble 2 contains the detailed information obtained during the occeptance t ests. The siren output sound level at each measurement location is shown along with the computed crithmetic overage value. Note that the variations in measured siren output sound level at the three locations are due to differences in the intervening ground surf ace, uneven terrain or nearby building reflections. Also, the maximum siren sound level at 4 f t above the ground in the near vicinity of the siren pole is shown along with the distance from the pole at which this level was measured.
Definitions of terminology cont ained in the tables are contained in Appendix A.
The variations in siren output level for each size of siren in the system is illustrated below:

l 3.2 Siren Range Tests Measurements of the siren sound level as a function of distance from the siren were made according to the procedures described in Section 2.2.
Measure-ments were made at distances near the design range and at several closer intervening locations between the design range and the siren. The design range for the siren depends on the background ambient, thus a given siren could have more than one design range depending on the direction of sound propogotion from the I
siren and the type of community nearby.
Toble 3 presents the results of the range tests in terms of the actual expected siren sound level versus the measured siren sound level. The actual expected level is based on the actual siren output level and frequency, os well as I
overage attenuotion corrections for air absorption using t est day weather conditions.
No attempt was made to correct for topography, unusual terrain features, or specific wind or temperature inversion conditions. Such conditions can cause additional attenuation from shielding, diminished attenuation from propa-gation over valleys, or major deviations in average sound attenuation due to refraction.
The octual measured ambient and siren sound levels were subject to consider-r ble variation with time during the measurement period. Therefore, on L90 sound pressure level in the octave band containing the siren fundamental and on L C-IO weighted level were selected as oppropriate metrics for the ambient and siren sound levels, respectively (see Appendix A for definitions).
The average diff erence between the octual expected siren sound level and the measured siren sound level at 53 measurement locations is +4.3 dB (or = 10.4 dB).
I Of course, where levels were only audible or where the background level was high enough to make the siren inaudible (seven locations), measurad levels are not available and, thus, the overage dif ference is biased toward those points for which the received levels are measurable.

3.3 Zone Tests Zone tests were conducted according to the procedures outlined in I
Section 2.3; that is, all sirens within a given zone were activated simultaneously.
Sound level measurements were made at 81 locations throughout the EPZ and the resultant data is shown in Table 4.
The data in Table 4 illustrate the measured siren sound levels at community locations and the ambient background levels. In most cases, the ambient levels were measured during a separate, and more extensive, ambient noise survey conducted prior to the siren tests.
A presentation of results showing the classification of zone test sites according to received siren sound level and observed signal-to-noise ratio is shown in Table 5.
Reducing these results further, the following table summarizes the zone test results in terms of the number of locations where either a 60 dB(C) siren sound level is received or a 10 dB signal-to-noise ratio is exceeded. In this case, C-weighted siren the signal-to-noise ratio (S/N) is the difference between the LIO level and the L s und pressure level in the octave band containing the siren 90 I

3.4 Community Resoonse Test and Statistical Survey Acoustic data obtained during the full-scale system test are shown in Toble 6.
Most of the measurement locations were identical to those where zone tests were monitored. At some locations, sirens from adjacent zones were closer and the received siren levels were higher than those measured during the zone tests.
Results of the community response test - telephone survey versus ocoustic measurements - are illustrated in Figures 2 and 3.
Detailed results of the telephone and in-pert >n statistical surveys are contained in Appendix C. Tables 7 and 8 summarize, by community and public site, respectively, the results of interviews conducted in both surveys.
Appendix D provides the detailed tabulated survey results in terms of all the topics addressed in the survey questionnaires.
The telephone survey was designed to obtain a statistically-valid determi-nation of the number of residential structures where the siren test was, or was not, heard. Several related topics were oddressed in the interview: size of household, activity of the time of the test, prior knowledge of the test, etc. In summary:
o A total number of 529 hour0.00612 days <br />0.147 hours <br />8.746693e-4 weeks <br />2.012845e-4 months <br /> Tolds were contacted.
o in 451 of these households, at least one person was home during the test.
o in these 45l households where someone was home, 66.7 percent contained at least one person who heard the siren test.
For the in-person survey, interviews were conducted with 135 people in nine public areas; 91.1 percent of this sampled population in these areas heard the siren test.

I Measurement Location, Acceptance Test The ocoustic measurement location around each siren during the siren accep-tance tests. Ideally, there were three positions, each 120 from each other, and all of the siren specification test position:
100 f t away and on the l
horizontal axis of the siren, in order to reach the horizontal plane of the pole-mounted siren, microphones were secured to the tops of telescoping aluminum poles which were held in place via guy lines. The poles were extended to approach the plane of the siren except that no pole was ever extended beyond 35 f t (for safety considerations). In addition to the 35 f t constraint, terrain around some sirens forced deviations from the above ideal, but these deviations were accounted for during analysis. Furthermore, some sirens could only be tested in two locations due to access constraints.
Each microphone was connected, via cabling, to either a sound level meter or one channel of a twxhannel tape recorder. In this manner, the data from two positions could be recorded while the data from the third position would be read " live".
Measurement Location, Community Response Test See Measurement Location, Zone Test Measurement Location, Range Test The acoustic measurement location in the community around tne siren of interest. The location designation is X.Y Z where X denotes the siren in the order of measurement; Y denotes an imaginary radial line from the siren to one of three measurement positions at or near the design range of the siren; and Z denotes whether the measurement location is at the design range (Z=0) or at on intermediate position along the imaginary radial line (Z = 1, 2, or 3) f rom which attenuation-with-distance information is made available (see detailed description in Appendix B: Range Measurement Location Listing).

Measurement Location, Zone Test The acoustic measurement location in each of the five zones within the EPZ.
Each location was randomly selected via a process which involved overlaying a grid on all inhabited creas within the EPZ with each cell of the grid being I,000 f t on a side. Each intersection of the grid was numbered such that a random number generator program could select 20% (or to the nearest whole number above 20%) of the total possible intersections as measurement locations. Where possible, subsequent measurement locations were added in a I
deterministic fashion to fill-in any gaps that the random selection process may have created. These added locations are preceded with an x on Table 4; for example, x A8.
The Community Response Test measurement locations consisted of a set of Zone Test locations selected in order to supplement the telephone survey response data with acoustic data.
Siren Design Rmge The siren design range (in feet) is the range at which the siren sound level is expected to equal its predicted value at a receiver according to the acoustic design procedures specified in the system design report: Wyle Laboratories Report WR 80-25, " Preliminary Design of Community Warning System at San Onofre Nuclear Generating Station," for Southern California Edison Company, June 23,1980.
Sound Level, Actual Expected The C-weighted, LIO (defined under Sound Pressure Level, C-Weighted and Statistical Sound Levels, L, respectively) sound level that would be expected x
at the indicated distance using the actual siren output sound level and frequency, and specific air absorption coef ficients calculated using the test-day weather conditions: for 460 Hz sirens, the absorption coefficient, cx, ranged from 0.68 to 0.74; and for 920 Hz sirens, <x = !.27 to I.44. The actual expected sound levels were calculated by Wyle using procedures specified in the system design report (please see Siren Design Range).
WYLE L A B O R ATO RI ES
I Sound Level, Ambient Background The sound pressure level, measured in the obsence of the siren signal, in the octave band containing the siren fundamental tone (500 Hz or I kHz) which is exceeded 90% of the time over a total cumulative measurement time of at least 10 minutes during any portion of a normal weekday between the hours of 7 a.m. and 7 p.m.
For most of the test measurement locations, the ambient level was measured during a separate survey performed prior to the siren tests. Data from the
'I ambient survey consisted of 10 to 20 minute samples taken at most of the zone and range test locations and several 24-hour samples taken at selected locations.
Ambient level measurements were also made during the siren testing program.
These ambient background sound levels are defined as the I
crithmetic average of the minimum sound pressure levels in the 500 Hz octave band measured for a period of approximately 2 minutes just before and just af ter each siren activation. These before-test and af ter-test levels were measured with the sound level meter controls set as follows:
o A-weighting - to eliminate the problems associated with correlating observed meter deflections with audible events (when C-or other restricted-band weighting networks are used, it is difficult to accurately measure the level associated with an acoustic event).
o "S low" meter response - as specified in the American National Standards institue (ANSI) Specification for Sound Level Meters (51.4-197i/R I976).
o Appropriate range setting - adjusted to provide a measurable reading of the minimum sound pressure levels on the meter scale.
Sound Level, Maximum Siren The maximum value of the siren sound level measured at any position 4 f t above the ground near the siren site which is normally accessible to the public.
This level is never to exceed 123 dB as set forth in FEMA /
.I A4 WYLE L A B O R AT O R I E S
This was measured by a person with a sound level meter (and ear protection) taking a reading every 10 f t as he walked away from the siren pole. At each 10 f t " station" the person stomed briefly, took a reading, and relayed the level to a helper who would enter the level and distance on a log sheet. The maximum levels and their associated distances from the sirens are shown in Table 2.
Sound Level, Siren The C-weighted, ! 10 (LIO(C)) siren sound level. For tope-recorded data, the L
levels in the four most important octave bands (500, I k, 2 k, and 4 kHz IO octave bands) were summed, on on energy basis, to obtain the siren output level L Appr pri te c rrections, dependent on the siren fundamental IO.
frequency, were applied to the A-weighted sound level meter data to obtain the siren LIO. Note, however, that since siren SCl2 is a directional, rotating siren, the above treatment is not appropriate. Therefore, maximum, slow-response C-weighted levels are shown for SCI 2 siren data (only).
Sound Level, Siren Output Design:
The manuf acturer's specified, C-weighted sound pressure level at 100 f t and on the siren's horizontal axis.
Actual:
The actual siren output level is the crithmetic average of the distance-corrected (i.e., normalized to 100 f t and on siren axis),
C-weigh ted, LIO siren sound levels measured at the three (nominal) radial positions described in Measurement Location, Acceptance Test (the siren is taken to be mounted at least 25 f t above a reasonably flat ground surface). The LIO(C) levels are computed exactly as are the Siren Output Levels (i.e., energy summation of octave bands from taped dato and correction of sound level meter data).
Sound Pressure Level (SPL)
The sound pressure level of a sound is 20 times the logarithm (base 10) of the ratio of the measured root-mean-square (RMS) value of the sound pressure to A-5 W Y L E L A B O R AT O R I E S

a refere,ce sound pressure.
The standard reference sound pressure is 20pN/m 2 (Ncte: 209N/m = 20 ppa = 0.0002 microbar = 0.0002 dyne /cm ),

I SPL = 20 logl0 I

Pref.
Sound Pressure Level, A-weighted (dB(A))
The frequency-weighted sound level which approximately correlates with the way that sound is heard by the human ear. The weighting, or filtering, quantitatively reduces the effect of low frequency noise (as does the human ear). The weighting is defined in the ANSI Specification for Sound Level I
Meters (S1.4-1971).
Sound Pressure Level, C-weighted (dB(C))
The frequency-weighted sound level which approximates the overall sound I
pressure level for the average range of human hearing. For frequencies between approximately 100 Hz and approximately 4,000 Hz, the C-weighting is essentially " flat." The C-weighted level is used here primarily due to the preponderance of siren specifications which quote this weighting.
I l
Statistical Sound Levels (L )
x A way of describing time-varying sounds that assigns a single level which is exceeded x proportion of the time during any given sample period. Thus, the sound level which is exceeded for a given percentage of the sample time can be described by:
i L: The same as L
- the maximum level (which is never exceeded O
max during the measurement period).
i L
LIO: The sound level exceeded 10 percent cJ the time. in practical terms, I
this statistical level is equivalent to on " average maximum" and was L
thus taken to most accurately represent the Siren Sound Level.

L90: The sound level exceeded 90 percent of the time. In proctical terms, this statistical level is equivalent to on " overage minimum" and was
{
thus token to most occurately represent the Ambient Background Sound Level. Using this statistic would automatically minimize influences from periodic short duration single event noise levels such as cars, circraf t, motorcycles, etc.

I 1 APPENDIX D Data Summary for Statistical Survey Conducted Following the Prompt Alerting System Test for the Son Onofre Nuclear Generating Station This appendix provides the results of a survey of residential structures (households) and individuals at public areas immediately following the full system siren test. Data is provided defining the segment who heard the siren test (1) within residential structures, determined through a telephone survey conducted on a statistically-valid sample of residential structures, and (2) outdoors in representotive public areas, determined through in-person surveys. The following information is provided: Guidelines to Interpretation of Summary Tables Summary l Telephone Statistical Survey of Households Within the Son Onofre Nuclear Generating Station Emergency Planning Zone Summary 11 In-Person Survey at Selected Areas Within the Son Onofre Nuclear Generating Station Emergency Planning Zone I l I I l l lI l D-l W Y L E L A B O R AT O R I E S
I Guidelines to Interpretation of Summary Tables Summay 1 - Telephone Statistical Survey in all tables, results are shown with absolute numbers over percentages; for example, in Table I, 529 households were contacted in the survey; of these 529, there were 72 (or 17.4% of 529) that were comprised of three household members. I Table 1 - Number of Persons in Household The number of persons comprising each of the 529 households contacted in the telephone survey is tabulated. This includes households where the siren test was heard as well as households where the test was not heard. Table 2 - Households in Which Original Respondents Heard Siren This table presents the number of households in which the original respondent (i.e., the first responsible adult contacted by the interviewer) heard, or did not hear, the I siren test. Other household members who heard the siren are identifi?d in Table 3. Table 3 - Other Household Members Who Heard a Siren Household members, in addition to the original respondent, who heard the siren, are tabulated. For example, in 106 households (or 22.9% of the total of 463), two (2) household members heard the siren. Table 4 - Number of Households in Which at Least One Person (at home) Heard Siren This table presents the number of households in which someone was at home during the siren test and at least one household member (at home) heard the test. If a I person heard the siren test at a location other than their home, they are included in Table 4A. The breakdown by location for people hearing the sirens is in Table 7. Table 4A - Number of Households in Which at least One Person Heard Siren (Either at Home or Not at Home) For the total number of households (i.e., respondents) contacted, this table identifies the number of households in which at teost one person heard, or did not hear, the siren test. However, this table includes persons who heard the siren, but I

may have been at a location other than their home of the time of the test. For example, o housewife may have heard the test at the market, but had returned .g home before the telephone interview was mode. J Table 5 - Number of People at Home at ll:00 a.m. I For all of the 529 households (i.e., total respondent) contacted, this table identifies the number of members of each household who were at home at 'l:00 a.m. on January 29. Table 6 - Time Siren Was Sounded The total number of households, out of the 529 interviewed, where the siren test was heard was 325. The time of day that the respondents recollected hearing the siren is identified on this table. The octual siren test was performed at II:10 a.m. I Toble 7 - Location of Person Hearing Siren The physical location of the persons hearing the siren in the 325 households (where the siren was heard) are identified as "inside" or "outside" the home, or "oway from hom e." I Table 8 - Location (Activity) of Person Hearing Siren Away from Home I This table identifies the activity of the respondent who heard the siren test (at the time of the test) and whether this activity was taking place indoors or outdoors. I Table 9 - Location (Activity) of Person Hearing Siren at Home - Inside The activity of persons who heard the test indoors is presented on this table. Table 10 - Location (Activity) of Person Hearing Siren at Home - Outside The octivity of persons who heard the test outdoors is presented. Toble i I - Loudness of Siren This table shows how loud the siren was perceived to be by all respondents who said they heard the test. I I o-3 m. <........:..
I I Table 12 - Reason Siren Was Sounded I All respondents were asked what they thought the reason was for the siren being activated. This table groups the response of the 325 respondents into six major categories. Table 13 - Similarity of Siren to Other Types of Sirens Respondents indicated how similar the sound of the siren they heard during this test was to other types of sirens normally encountered, i.e., police, ambulance, fire engine, etc. Table 14 - Prior Knowledge of Siren All 529 respondents were asked if they had any prior knowledge of the siren test which took place on January 29. Their answers are indicated on this table. Table 15 - Number of Houses with Windows Open/ Shut All 529 respondents were asked the question, "Were there any windows in your house open at the time of the test?". 161 said they were open; 360 said windows were not open; seven said they did not know. I Table 16 -Sex of Respondent I This table identifies the sex of all 529 respondents. Tables 17,18,19, 20 - Crosstabs Tables 17,18,19, and 20 compare the variables: (1) number of persons at home during the test with (2) households in which at least one person heard the test, and (3) households in which no one heard the test. A comparison is mode for each of the four communities. For example, for Son Clemente, in all households where three people were at home during the test, there were 17 households (out of a total of 207)in which at least one person heard the test and one household (out of a total of 81) in which no one heard the test. Table 21 - Heard Indoors by Window Position For the 234 households where the siren was heard "at home indoors," the number of homes with windows which were open or shut are identified.

I Table 22 - Loudness of Siren by Location of Heorer This table provides o breakdown of the loudness dato presented in Table i1. For all those who heard the siren, it gives the perceived loudness by locations, i.e., inside house, outside, house, away from home. Summary II - In-Person Survey Dato presented for the In-Person Survey follows a format similar to that for the Telephone Survey. Servey results are provided for each of the nine sites.

L n l B l 1.0 NTRODUCTION A prompt olerting system consisting of 40 sirens has been installed within the 10-mile Emergency Planning Zone (EPZ) of the San Onofre Nuclear Generating Station (SONGS). The system is deployed throughout community, beach front, military, and commercial areas in parts of Orange and San Diego Counties. Control md activation of the system is retained by five agencies; namely: o Orange County (OC) o San Juan Capistrano (SJ) o Son Clemente (SC) o State Parks (SP) o Camp Pendleton (CP) Locations of the 40 sirens throughout the 10-mile EPZ ore illustrated in Figures l A I and IB. Sirens within each control zone are prefixed with the letter codes shown above. A test to determine performance of the system was conducted on May 24, 1982, during which all sirens were simultaneously activated and set to operate for o period of 4 minutes. During this test, sound level dato comprising ambient background noise levels (pretest and post-test) and siren signal levels, were measured at 28 sites within the 10-mile EPZ. I I I I B I (
- These include a previously instoiled sir n owned by the City of Son Clemente.

Each controlling agency was to activate its respective sirens offer confirmation of readiness by all other agencies. In practice, the system was activated at 1418 hours on the test day. Timer controls of each siren I were preset to provide a siren operation period of 4 minutes. The following is a summary of siren deviations from the scheduled performance: Sirens not activated: OC07, OC08, SC04, CP08. Sirens with foreshortened periods of netivation: CP03. Sirens with protracted periods of octivation: l SJ01, SC01, SC03, SC06, OC04. All other 30 sirens operated in accordance with the scheduled performance. I 2.2 Sound Measurement Loco! ions Twenty-nine sound measurement locations were used in the May 24,1982, test. These 29 locations comprised the main body of sites at which deficiencies of I signal level or signal-to-(ombient) noise were noted in a previous test of the system during January 25 to 29,1982. The measurement sites were identical to those previously used, which were part of a rando. ily selected sompte of 81 sites covering all control zones and agencies. Figures 2(a) through 2(i) show the 29 sound measurement locations (high-l lighted) in relation to the siren locations. Table I contains a brief description of each sound measurement location, as employed by the respective measurement l teams to identify sites. In each reference to site locations, the following prefixes have been used to ( relate the sites to the respective zones (agencies): I l Instrumentation failure at one site reduced the number of sites with data to 28.

In addition, these sound level meters were supplemented at selected sites by analog tape recording systems which comply with the require-ments of ANSI S6.1-1973, " Qualifying a Sound Data Acquisition System." Each item or system of measurement equipment was calibrated in accordance with the manufacturer's specifications. Field calibrotions were performed prior to and offer each test sequence by means of an acoustic calibrator. All analog recordings of sound pressure were preceded by on acoustic calibration signol identical to that used for field calibration of measurement equipment. Personnel and Briefings The acoustical measurements were performed by 29 engincering personnel. These personnel were distributed into seven teams, each of which was supervised by on engineer who was highly experienced in the acquisition of sound level dato I and who had detailed knowledge of the survey creo and measurement sites. I Formal briefings and training sessions were held between 9a.m. and l I i 1:30 a.m. on May 24,1982, to ensure that personnel were fully familiar with the requirernents of the sound level dato acquisition process using the particular type of instrumentation allocated to them. Dispersal to measurement sites commenced at 12:45 p.m. on the test day and all personnel were in place prior to siren activation. Data Acquisition Table 2 is a replica of " measurement procedures and test log section" sheets issued to each sound measurement engineer. Separate instruction sheets on system I 2-13 WY L E L A BO R ATO RI ES W I operation, calibration procedures, and site locations were also issued to engineers os part of a Log Book. Eoch log book, together with instrumentation used in the survey, was inspected and/or tested for completeness and conformation with procedures at a debriefing session af ter the test. The data acquisition procedures comprised four tasks, as follows: Calibration: Each measurement system was calibrated at the measurement site by means of an acoustic calibrator. Pretest Ambient Noise Measurement: A measurement was obtained of the typical ambient (background) noise level at the measurement site prior to siren activation. This measurement was performed to acquire information on the typical value of L90, the sound level exceeded during 90 percent of the measurement time period, i Siren Signal Measurement: During the activation period of the siren, sound leve! data were acquired which provided information on the maximum and minimum sound levels (at the site) which were directly attributable to the siren signal. To minimize interference by wind noise, the si:en levels were measured in terms of A-weighted levels, and subsequently corrected to C-I weighted levels for this report. Post-Test Ambient L Measurement: The procedure for measuring ~ ambient (background) nuise at the site was repeated after all siren signals were known to have ceased.

!I 3.0 TEST RESULTS 3.1 Typical Siren Signal Characteristics l Figures 3 and 4 show one-third octave band frequency spectra for short-term samples of the siren signals recorded at Locations A4 and C21, respectively. These l spectra illustrate that the primary frequency content of the siren signals was in the 315 Hz and 400 Hz one-third octave bands, with minor harmonic levels at higher f requencies, and that the siren signals at these two locations were well in excess of noise levels in adjacent frequency bonds. Tables 3 and 4 show the statistical chorocteristics of the ambient noise and siren test signals at each of the two locations (A4 and C21). For Location A4, I Table 3(a) stuws the ambient noise statistics and Table 3(b) shows the siren signal data. Similarly, for Location C21, Table 4(a) shows the ambient noise chorocter-istics and Table 4(b) shows the siren signal chorocteristics, in each of these tables, the L ' 'l' 'l0, etc., values are the sound pressure levels exceeded for 0 percent, O I percent,10 percent, etc., of the sompte time period. These values are shown to be evoluoted for each one-third octave band, for the overall A-weighted Sound Level, and for the overall Sound Pressure Level (Linear). Examination of these tables shows that the siren signal levels of these two locations were.well in excess of ambient background noise levels in the octave band containing the siren signol. (It should be noted that these short-term samples were extracted from the full record of the test. They are representative of, but do not I necessarily agree exactly with, the test data submitted by the engineers for the complete test period.) 3.2 Summcry of Measured Test Data Table 5 is a compilation of all croustic dato acquired during the May 24, 1982, siren system test. Evoluotion of the relationship between the Sound Level Meter dato and the statistical values of (a) LIO, dB, for the siren signoi level, and (b) the ambient noise level, L90, dB, in the octave band containing the siren signal frequency, indicated that no corrections needed to be opplied to the measured sound levels in compiling the Table 5 summary. These metrics, L nd L re rec gnized indices of signal intrusiveness IO 90, and ambient background noise level, respectively. These are consistent with research supporting FEMA Report CPG-l-17," Outdoor Warning Systems Guide," as ref erred 1o in NUREG-0654. 3-1 WY L E L A BO R ATO RIES

U. e n ( SONGS Evacuation Warning System Evaluation of Use of Radio Alert Systems INTRODUCTION The City of San Clemente has requested that Southern California Edison study the feasibility of supplementing the SONGS Emergency Warning System with a National Oceanic Atmos-pheric Agencies (NOAA) Radio Alert System. An evaluation of radio alert systems was performed during the design process which led to the selection of sirens as the primary method for alerting the public within the Emergency Planning Zone (EPZ). This report is a summary of that evaluation. DESCRIPTION Radio Alert Systems are designed to automatically receive and broadcast warning signals and associated instruc-tional messages. These receivers are designed to operate in conjunction with one of two broadcast systems: NOAA Weather Service (NWS); Emergency Broadcast Systems (EBS). The NOAA Weather Service is the sole government source for directly alerting the public to imminent emergencies, I including severe weather and other immediate dangers. General weather is broadcast 24 hours a day on one of seven VHF fre-quencies. In event of an emergency, the instructional message broadcast is preceded by one or two tone alerts. The Emergency Broadcast System was installed by the Federal Government to provide emergency warning to the public by utilizing over 90 percent of the existing commercial broad-cast stations. Each major broadcast station is required to have encoder and decoder / receiver equipment. This system uses an alert signal consisting of two precise audio tones trans-mitted simultaneously. The instructional messega is broadcast after the alerting time. Radio Alert Systems are single stage; that is, when an alert system is broadcast, all units within the transmitter's coverage area are automatically turned on and the instructional message transmitted to the public. The authority transmitting the message controls every radio alert receiver in the system. REQUIREMENTS The Emergency Warning System must be designed to comply with the "concapt of operations" and " criteria for acceptance" of a prompt alerting system as defined by Attachment C
1 ( Appendix 3 of NUREG 0654, Criteria for Preparational Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants. That is, the system must be designed to provide a primary means of alerting the public to i an impending notification (by public authorities) by broadcast 1 media. The criteria of NUREG 0654 states that: "The primary means for alerting the public to an impending notification by public authorities may be any combination of fixed, mobile or electronic tone generators which will convey the alerting signal with sufficient timeliness and intensity to permit completion of notification by broadcast media in a timely manner." In addition, the criteria for acceptance of the alerting system require that - A system which expects the recipient to turn on a radio receiver without being alerted by an acoustic alerting signal or some other manner is not acceptable. - The minimum acceptable design objectives for coverage by the system are: (a) Capability for providing an alert signal to the population on an area-wide basis throughout the 10-mile EPZ within 15 minutes. (b) The initial notification system will assure direct coverage of essentially 100 percent of the popula-tion within 5 miles of the site. (c) Special arrangements will be made to assure 100 percent coverage of the population within 45 minutes who may not have received the initial notification within the entire plume exposure EPZ. - Organizations proposing the use of sirens retain the responsibility for cost / benefit decisions which might involve the use of alternative methods in thinly popu-lated areas where such methods are cost effective while meeting the notification criteria for the EPZ. DISCUSSION The major factors to be considered in the selection of the primary alerting system are: 1 i
9, - ) l e 1. Population Coverage - the system must be capable of alerting the public outdoors and indoors within the EPZ to the criteria of NUREG 0654. 2. Reliability - the system must be dependable, simple and rugged. 3. Testing and Inspection - the system must be amenable to direct periodic in-place testing and inspection to assure proper operation. 4. Maintenance - the equipment must be designed for easy maintenance and be available for periodic maintenance. 5. Cost Effectiveness - the system must be cost effec-tive. Radio alert systems are evaluated for these factors as follows: Population Coverage Tone alert receivers are divided into two categor-ies: residential and commercial. The residential ( receivers are designed to provide warning inside a private residence. The commercial receivers are designed to provide warning to several areas inside a building. The population to be covered within the EPZ is expected to spend 40% of its time outside. Prime areas to be covered include: State Beaches, City Beaches, and commercial shopping areas. Neither of the NWS or EBS radio alert systems would provide adequate coverage of these areas to meet the requirements of NUREG 0654. The NWS radio alert system uses VHF frequencies to transmit the emergency broadcast warning. There are no known transmitters for NOAA within 20 udles of SONGS. The topography of the EPZ is characterized by coastal bluffs, rolling terrain with inland hills and canyons. This topography is not suitable as a receiver area from a distant NOAA transmitter. A slave transmitter station would be required in the area to accommodate the NWS radio system. Reception is also affected by weather conditions, barriers, metal shielding and radio traffic. The EBS radio alert system uses AM transmission which does cover the topography and does not require additional transmitters. (
d -4_ i I Reliability The tone alert receivers are simple but are not designed for rugged use, being passive indoor electronic equipment. They also feature:
- 1) a flashing dial light when a warning signal has been sent; 2) a minimum volume setting (ie audio broadcast cannot be fully muted); and
- 3) backup battery power.
The units are not tamperproof and are not designed to resist severe abuse. The units are also susceptible to false operation. Spurious signals from such sources as radio " ham" operators and sonic garage door openers can activate the receivers and cause them to emit alert tones. No broadcast would be transmitted during false operation but the receiver must be reset. Testing and Inspection To provide coverage for the EPZ at least 15,000 tone alert receivers would be required. The NUREG 0654 criteria would require periodic testing and inspection of these receivers in-place. Using a statistical sampling method at least 5,000 receivers would be tested per year or approximately 25 receivers per day. Since the receivers i would be located within residences all inspections and tests would require scheduling of appointments with residents. Considering the number of residents not avail-able during daytime, the logistics of the inspection and testing program become difficult and affect the overall reliability of the system to alert the public. Maintenance The tone alert receivers are simple radios and would require little maintenance. Commercial grade receivers have functional lives of 6 to 8 years. This life is dependent on the use or abuse of the receiver. To assure reliability the receivers would be replaced or maintained every five to seven years. This would equate to the possible replacement of 15,000 receivers eight times in the lifetime of San Onofre, or a total of 120,000 receivers over 40 years or 3,000 receivers per year. The maintenance schedule would coincide with the inspection and test program whenever possible and would be subject to the same logistics problem. Cost Effectiveness ( To evaluate the cost effectiveness of the tone alert
- I system, the initial costs, operating costs, testing costs and replacement or life expectancy costs were compared to those of a siren system using ll5dB sirens.
Residential grade alert receivers were used in the comparison and the installation of a slave transmitter was not included. For areas in which 36 residences or more are to be l covered, sirens are the most cost effective means of alerting the public. That is, in densely populated areas, sirens are more cost effective than radio alert systems. CONCLUSION As a primary alert system, the National Oceanic Atmospheric Agency (NOAA) radio alert system is not acceptable because:
- 1) it does not provide adequate coverage of the population of the EPZ; 2) it is subject to false activation;
- 3) it is not amenable to in-place testing and inspection and maintenance; 4) it requires an extensive replacement program;
- 5) it is not cost effective for dense population areas; and
- 6) it requires installation of a local NOAA transmission station.

7 O 1 l Memorandum for File Radio Tone Alert Systems l l Introduction Radio Tone Alert Systems are designed to automati-cally receive and broadcast warning signals and associated instructional messages. These receivers are designed to operate in conjunction with one of two broadcast systems: i NOAA Weather Service (NWS); Emergency Broadcast Systehs (EBS). The NOAA Weather Service is the sole government operated source for directly alerting the public to imminent emergencies, including severe weather and other immediate dangers. General weather is broadcast 24 hours a day on one of seven VHF frequencies. In event of an emergency, the instructional message broadcast is preceded by one or two l tone alerts. The Emergency Broadcast System was installed by the Federal Government to provide emergency warning to the public by utilizing over 90 percent of the existing commercial broadcast stations. Each major broadcast station is required to have encoder and decoder / receiver equipment. This system uses an alert signal consisting of two precise audio tones transmitted simultaneously. The instructional message is broadcast after the alerting tone. Radio Alert Systems are single stage; that is, when an alert signal is broadcast, all units within the transmitter's coverage area are automatically turned on and the instructional message transmitted to the public. The authority transmitting the message controls every radio alert receiver in the system. On October 29, 1981, a report summarizing an Engineering and Construction feasibility study on the use of radio tone alart systems for the SONGS Emergency Evacuation System was submitted to Mr. F. C. Jackley for transmittal to the San Clemente City Council. The study had been per-formed in response to the request of the City Council. It was the conclusion of that report that a NOAA radio tone alert would not provide adequate public notification as a primary notification system. Upon submittal of the report, the City Council initiated their own survey of the National Oceanic Atmospheric Agency (NOAA) radio tone alert system. In anticipation of Attachment D
the City's report, Mr. F. K. Massey requested in his letter of December 15, 1982 that further information on NOAA usage be obtained. To comply with Mr. Massey's request, the Technical Support Group of Apparatus Engineering has contacted forty-five (45) utilities owning or operating fifty-five (55) nuclear facilities throughout the United States. The infor-j mation obtained from those utilities on their alerting system has been used to respond to Mr. Massey's questions in this memorandum. Summary The survey of the industry has been completed and responses to Mr. Massey's questions have been provided. The results of the survey show that: 1. Only Georgia Power Company uses NOAA radio tone alert system as the exclusive means to alert the public within the EPZ for the Hatch nuclear facilities. 2. Nine facilities use sirens with NOAA radio tone alert systems as the means to alert the public within the EPZ. 3. The use of NOAA radio tone alert systems is limited to: a) areas with low population density or a limited number of structures to be covered; and b) selected institutions (i.e. hospitals, schools). 4. Existing NOAA broadcast facilities do not cover the entire cities of San Clemente or San Juan Capistrano within the 10 mile EPZ. 5. Additional transmitters would be required to cover the EPJ. 6. NOAA radio tone alert receivers cost between $23 and $285 7. The industry has no uniform maintenance program for the radio tone alert receivers or the overall alert systems. I 8. There are no NRC approved alert systems to date. Systems have been tested and reports submitted to various FEMA regions but no system has been approved. l l
9 The informatfon contained in SCE feasibility study dated October 29, 1981 is correct and valid. 10. The information contained in the City of San Clemente Administrative Report of February 3, 1982 is inaccurate, incomplete and misleading. i i 9
' I -k-4 Discussion The following are the responses to Mr. Massey's questions: Question 1 Which nuclear facilities are using NOAA and why? For what population and population density? Answer 1 e A. 1. Thirty (30) facilities are using sirens alone as the primary alert system. 2. Twenty-four (24) facilities are using sirens with radio tone alert systems. Of this number, ten (10) facilities are using sirens and EBS; nine (9) are using sirens and NOAA; and five (5) are using sirens and other miscellaneous radio tone alert systems. The facilities using sirens and NOAA are: Utility Facility Maine Yankee Atomic Power Maine Yankee Niagra Mohawk Power Nine Mile Point Niagra Mohawk Power & Power Authority of New York James Fitzpatrick Vermont Yankee Nuclear Power Vermont Yankee Yankee Atomic Yankee Rowe Northern States Power Monticello Prairie Island Alabama Power Company Joe Farley 1&2 Tennessee Valley Authority Browns Ferry 3. One (1) facility is using NOAA as its primary alert system. The facility using NOAA is: Georgia Power Company Hatch 1&2 B. Georgia Power selected the NOAA radio tone alert system for the Hatch facility because it was more cost effective for the area than other systems. Factors considered were: low population density, few structures to be covered, remoteness of population, familiarity with NOAA by the population, and the stability of the population (long term residents, not transients). l l " ~
5-The utilities using sirens and NOAA radio tone alert systems selected the sirens for coverage of dense population areas and the radio tone alert system for low population density areas or for selected institutions (i.e. hospitals, schools). Cost effective use of each system was the major consideration in the selection. C. The general population covered by NOAA systems is rural, while the general population covered by sirens is urban. D. The population density covered by NOAA radio tone
- 1 f
alert systems varies'but is less than 30 structures [l per square mile. 9
- ?
' Question 2 Which, if any, are using NOAA as the primary alert method? Why? Answer A. In the strict sense, all of the utilities using NOAA radio tone alerts consider them to be a primary alert method. It must be understood, however, that only one, Georgia Power Company (Hatch 1&2), is using a NOAA radio tone alert system to the exclusion of all other means. It is therefore their primary means of alerting the public. Four (4) additional utilities: Vermont Yankee (Vermont Yankee), Yankee Atomic (Yankee Rowe), Niagra Mohawk Power (Nine Mile Point and James Fitzpatrick), and Alabama Power (Joe Farley) make extensive use of NOAA radio tone alert tvstems and they also are considered ?rimary. The remaining three (3) utilities: Maine Yan<ee Atomic (Maine Yankee), Northern States Power (Monticello and Prairie Island), and Tennessee Valley Authority (Browns Ferry) use NOAA radio tone alert systems as supplements to the sirens. B. The utilities using NOAA radio tone alert systems as primary alert systems have done so due to the low population density in the EPZ which makes them more cost effective than sirens (see Answer IB). ~ 0 e t
~ -7_ Question 3 Which, if any, are using NOAA and sirens to cover the same population? If so, why? Answer A. As stated in Answer 2A, only three utilities use sirens and NOAA radio tone alert systems to cover the same population. Those utilities are: Maine Yankee Atomic (Maine Yankee), Northern States Power (Monticello and Prairie Island), and Tennessee Valley Authority (Browns Ferry). B. The NOAA radio tone alert systems are being used to enhance coverage in institutions (i.e., hospitals, schools). s i i i l i l
- Question 4 f Where NOAA is being used in conjunction with sirens, what criteria determined use of each method (population density, economics, etc.) Answer Where NOAA radio tone alert systems are being used in rural areas, the major criteria for selection were the cost factors associated with procuring and installing large 4 numbers of sirens to cover a small population. The NOAA radio tone alert system is the cost effective method to be used when only a few structures are to be covered. Where NOAA radio tone alert systems are being used in institutions, the rationale for usage was for enhanced coverage of those populated places which may have high indoor ambient noise levels and for which penetration by an exterior noise source was impractical. An additional consi-deration was the availability of a responsible monitored control point at the institution. i 4
.e _g_ l Question 5 l Where NOAA is being used, how many radio units did the utility furnish and what are their actual / projected maintenance practices and costs. (Do they plan to maintain equipment every year, how do they determine that the units remain operational, etc.) Answer A. The quantity of NOAA radio tone alert systems provided by each utility for their facilities is given in the following table. It should be noted that the utilities did not in all cases distribute the receivers but sometimes just made them available. Utility Facility No. NOAA RTAS Maine Yankee Atomic Power Maine Yankee 25 Niagra Mohawk Power
- line Mile Point 2100 Vermont Yankee Nuclear Vermont Yankee 3600 Yankee Atomic Yankee Rowe 3000 i
Northern States Porer Monticello 75 Prairie Island 75 Alabama Power Company Joe Farley 1&2 2400 Tennessee Valley Authority Browns Ferry 65 Georgia Power Hatch 1&2 2400 i B. None of the utilities has eith2r actual or projected maintenance costs. Maintenance practices ranged from turning the maintenance responsibilities over to the local community or to the state or to providing replace-ments if a damaged unit is returned to the utility. There is no clear cut plan for the industry regarding maintenance. l I l t
,' Question 6 Specifically, what NOAA broadcast facilities exist ( in Southern California, and which if any provide coverage in San Clemente (specific degree of coverage). If none are available, how long would it take to get a transmitter installed and at what cost? Answer A. Four broadcast facilities for NOAA exist in Southern California, in San Luis Obispo, Santa Barbara, Los Angeles (Mt. Wilson), and San Diego, at frequencies of 162.55, 162.40, 162 55, and 162.40 MHz, respectively. B. Partial coverage of San Clemente is provided from San Diego at 162.40 MHz. C. Specific coverage in San Clemente is as follows: (1) All coastal areas receive the signal from San Diego; (2) All interior areas south of Camino de Estrella receive the signal; and (3) Interior areas north of Camino de Estrella do not receive the signal well. D. Specific coverage in San Juan Capistrano is as follows: (1) All coastal areas receive the signal; and (2) Interior I areas i.e. San Juan Creek Road and Ortega Highway do not ( receive the signal. E. A full cost analysis is required to obtain an accurate estimate of installing a slave transmitter. Georgia Power installed a transmitter at a cost of $50,000, howeve-they have indicated that if they were to l do the project over they would install a better unit (approximately $80,000). Yankee Atomic installed a transmitter at a cost of $80,000. Both of these installations are in low land value areas. Adjusting for Southern California, it is expected the cost would be $80-100,000 with an installation time of three months. \\ i - ' - - - - - ~ ~ ~ ' - " " ' " " ' ' ' " ' ' ' ~ ~ ~
t Question 7 i What are the actual purchase costs per NOAA radio unit? Does NOAA provide maintenance for their units? If so, what are the costs? Answer A. See attached Tables for cost and performance informa-tion for radio tone alert systems. B. The National Oceanic Atmospheric Agency (NOAA) does not maintain radio tone alert systems. The Agency does provide maintenance of a transmitter ranging between $300-$2000 per year. I l l I

~7 12 - Discussion (cont'd) ( Since Mr.7Massey's request for information, the City of San Clemente 'has produced an Administrative Report on NOAA radio tone alert systems. Review of that report indicates several inaccurate and misleading statements. Some comments resulting from the review of the Administrative Report are: 4 a. Our review of industry alert systems verifies that the j NRC or FEMA have not approved any alert system. Approval l 1s based on performance of the alert system to meet l NUREG 0654 criteria and to this date, evaluation of the alert systems performance has not been completed. b. The City report does not discuss the actual requirements i of the alerting system. Its only intent seems to be the i demonstration that NOAA systems can be used. It ignores i the requirements which the system must meet and which j are given in the feasibility study. The conclusion of that study is still valid. NOAA radio tone alert systems are not adequate as a primary notification system in the EPZ. 1 c. The community's perception of "what to do in the event .the sirens are activated" is an education program requirement. The siren alerting system requirement l l is to notify the community of an emergency. Ij d. Since the sirens tested in January 1982 demonstrated performance problems, the report's conclusions on the coverage of the alert system is premature until necessary 1 corrections have been made and the system retested. i i e. The NOAA letter states the uncertainty as to whether i or not National Weather Radio meets NRC or FEMA criteria although it is an option. 4 1 i f. The sites using NOAA radio alert systems are incomplete in the City report. j g. The costs presented in the City report for the NOAA installation of a transmitter are low. i h. It should be noted that NWS has recently closed several f. stations across the country due to budget constraints. 1. The price range on radio tone alert receivers is between $23 and $285 1 4 j. The City of San' Clemente letter to the NRC is incorrect in stating that SCE indicated a siren system is the only means " acceptable to the NRC" or that the "NRC would not j authorize" such a system.
~~n 13 - k. There are only 14 sirens in San Clemente. i 1. The feasibility study was performed by Southern California Edison. The NRC letter correctly states the requirements of the m. alert system and the responsibility for the'demonstra-tion thereof. Conclusions 1. The industry h'as been surveyed and responses obtained for Mr. Massey's questions. 2. The Admidistrative Report of the city of San Clemente-is incomplete and inaccurate. 3.

Seject: Altematin Strategies For Alert And lernig
Dear k. Jackley:
Enr since a han been arting on this alert mening probim, I han been concemed about coming $ vith a systs that igroves our means of comunication with the public. As you know, a siren systes is still subject to a lot of debate and w are still asalting the result of the study. Afklitionally, w already know that expanding the siren systs into the bad contry who it is denloped is ping to be wry expensle. Dur discussions regarding the 110M Systen how been fraught with { problems too. I know you guys are act happy with the prospects of that systs became of cost, saintenante, repair and control. In ny ongoing search to find a viable alternatin, I thist I have nearthed smething that my be a potential solution. I muld lite you to review the following concept before I eer advise the City Concil of its existance. llLr*= are siele. li this systs can do all of the things that the WA SysteipdlL I miy find sirself in"a piisitio~n cf arguisjagdastb own proposal. ~ ~ Therefore, I muld like to have dialogue with you first. The concept is called Cable Intercept. As you know, our City is serviced by TWCablevision. Currently, TM has 12,158 sescribers in the City of San Clmente and Capistrano Beach. They serve this entire area through one " head". This unans that all television sipals that cae into our City y through one trensmitter which is located on lleservoir 5. I recently at with representatives of Cablevision. They were Joani Denny, Russ Bottjer and Gary Cax. Their facilities are located at 27611 la Paz Ibad, Mission Viejo, California. The purpose of the discussion as to determine if Cable Intertept muld allow a to 'preegt' all of the television sipals simultaneously.

~ r.. 8 g s { Mr. Bud Jackley Marth 11,1982 ( p mat a deterened is that there is technology available to put a piece of equipment in the transmitter room that will allow j us, right fm the E00, to activate a piece of video tape equipment g that would send out pre-recorE witten sessages owr all l I television chamels sinaltaneously. The equipent muld allov 1 j several different types of pre-programed sessages for exasple, f you can hve one pre-planned message for shelter protective actions, another for evace f i The equipment can provide character sessages.1.E. written text that will rotate on the screen of the video taped sessages. I r l~ There is een a possibility that with a very sophisticated version [ of Cable Intercept that w would be able to ske direct broadcasts in an energency over the cable. The cost for tbese types of systecs range from as little as $10,000 to a axima of about $100,000. 5 The beauty of this concept is that if it wre to be uployed, it requires an absolute sinias of mintenance ad a axiaz of liability and control for energency operations. This is not to say that there are te problees. I as advised by the cable people that they are regulated by FCC rules and there sight be same problems regarding preesption er yielding of air l' time. Additionally, they feel that some kind of annal testing screen muld have to be incorporated, not unlite B5 Tests to avoid liability. At best, the systen muld still not eliminate the need for sirens, but my go a long my toerds totally elirineting the criticism of penetrating the buse noise. As you my recall, a large nder of our respondents who 'clain' that they didn't hear the siren was becase their T.V. as on. This system, cuplete with safegards like w have on the siren, would give us ismediate access to that comunitation link. The T.M. people are enthusiastic about the concept. They state that w could achieve this capability easily within the 160 days of activation. I as sending you this letter in a written form for two reasons. The first is to clarify my own thoughts on the idea. The second is to formily request you to evalute this idea and let me know what your thoughts are. Quite frankly, I feel that if this syste: can do all of the things that are indicated, I muld be very willing to fight the battle of elisinting my own recomendations on kW. 7 Nope to hear fra you in the near future.
