11 County Interactions County Interactions Training Entergy conducted training of personnel at the county Emergency Operation Centers and Warning Point Centers during January and February 2007, with training for one Warning Point performed in April 2007.
Entergy has provided a written lesson plan of training topics to county officials to facilitate additional training sessions and will provide retraining on these topics as requested.

Open Issues
12 FEMA Interactions FEMA Interactions FEMA participation in project design overview meetings with New York State, Counties and Entergy to develop design and implementation of new system Review and comment of design report Design report review meeting FEMA approval of design report FEMA observation of testing Follow up meetings and teleconferences Design report supplemental information submittal
13 System Testing Acoustics Mike Slobodien, Director Emergency Planning
14 Acoustic Testing Acoustic Testing
- Pre Operational Testing
- Individual Sirens per ANSI S12.14
- Individual Sirens using ground based measurements
- These measurements serve as a basis to validate the input assumptions to the sound propagation models
- Post Operational Testing
- Far field measurements to validate sound propagation model and demonstrate conformance with FEMA REP-10 Section E.6.2.1.
15 Acoustic Parameters Acoustic Parameters Elevated 50 feet Ground 3-5 feet on axis off axis Maximum Peak Elevation Measurements 100 feet)

16 Testing performed between June 5 and June 15 Performed by independent acoustics engineering laboratory, Blue Ridge Research and Consulting (BRRC) of Ashville, NC 20 sirens selected that meet ANSI criteria for elevated testing All tests were performed by BRRC using ANSI Type 1 instruments Pre-operational Test Results Pre-operational Test Results
17 Acoustic Parameters Measured by BRRC Acoustic Parameters Measured by BRRC Maximum peak off axis Maximum peak off axis Maximum peak on axis Maximum peak on axis Average maximum peak off axis Average maximum peak off axis Average maximum peak on axis Average maximum peak on axis Average on axis Average on axis Average off axis Maximum off axis Maximum on axis Elevated Measurements Average off axis Maximum off axis Maximum on axis Ground Level Measurements

Average L Peak All units in dBC
19 Overall Results Overall Results
- 19 of the 20 sirens in the test tested satisfactorily (one siren did not respond properly and will be replaced or repaired)
- For the 19 sirens, the average maximum peak on axis, measured at the 50-foot elevation was 123.4 dBC with no individual siren less than 120 dBC
- The sound propagation models run at both 120 dBC and 122 dBC both demonstrate that the FEMA criteria are met
20 Acoustic Testing Acceptance Criteria Acoustic Testing Acceptance Criteria 10 dBC over ambient Population < 2000 per square mile 60 dBC OR Population < 2000 per square mile 70 dBC Population > 2000 per square mile FEMA REP-10 section E.6.2.1
21 System Testing Activation Tim Garvey, Project Manager
22 System Testing Activation System Testing Activation System polling, full volume, silent tests All activation methods TCP/IP Radio-microwave Radio-T1 Integrated test Activation from all 12 control stations

24 System Activation Test Results System Activation Test Results
- Test results are good on average, but better consistency is needed for radio pathway
- Identified causes of inconsistent test results
- Failed power supply for microwave equipment at Grasslands tower
- Testing protocol (initial test conditions)
- System alarm message interference with activation signal
- Currently investigating cause of inconsistent test results
- Independent system assessment
>> Field testing and walkdowns
>> Systematic evaluation of simulcast radio system
>> Evaluating radio system, hardware, software
25 Independent System Assessment Status Independent System Assessment Status
- Overall design of the system is good
- Several recommendations for improvement
- Enhance system monitoring capability
- Improve RF filtering at the simulcast tower locations
- Update of microwave equipment firmware for consistency
- Implementation of recommendations is in progress
- A single, specific cause for inconsistent results has not been identified
- Assessment activities are on-going
26 System Activation Testing System Activation Testing
- Plan for Completion
