Licensee Action on Previously Identified Items-Relating to the Prompt Public Notification / Warning System (0 pen) 50-295/82-05-01; 50-304/82-05-01: What percent of the popula-tion between 5 and 10 miles will not hear the initial signal? At this time neither the Lake County, Illinois or the Kenosha County, Wisconsin sirens installed by the licensee have been incorporated into the respective county siren system. This should be done in each county within the next 6-8 weeks as stated by a licensee repre-sentative.
The licensee's installed sirens in both Lake County and Kenosha County are presently operable and can be activated by an encoder at the respec-tive county offices, independent of any existing county siren system.
When connected to the existing county siren system, one encoder will activate the entire system at one time.
The radio frequency of the Lake County sirens must be changed to the same one being used for the other county sirens. The licensee's present siren radio frequency has local interference and noise. After the licensee's sirens have been incorporated into the county siren systems, monthly tests will be conducted at a full alarm mode. The August 1982 monthly test will include a coverage test of the siren's audibility range. The licensee intends to send cards to certain residents in the outer audibility arc of each siren. These cards
~
will be completed by the residents indicating whether or not they could hear the siren from their location.
This test, when the results are projected and tabulated, should provide information to determine what percent of the population between 5 and 10 miles will not hear the initial signal. Results will be made known to the inspector at that time.
(Closed) 50-295/82-05; 50-304/82-05-02: What QA/QC program has been established to assure continued reliability of the alerting (siren)
system? The licensee has two separate contractors, one for Lake County and the other for Kenosha County who are responsible for con-tinuing maintenance and repair of the siren systems.
If any sirens fail to alarm as a result of the monthly test, the County will notify
_

>
the contractor for repair work. The licensee has also established a six month preventative maintenance program with the respective con-tractors which includes component inspection and repairs, radio and electrical repair including the-encoder and checks for electrical grounding and lightning arrestors.
If this program is followed on a timely basis along with the routine monthly alarm tests, the reliability of the siren system should be maintained.
(Closed) 50-295/82-05-03; 50-304/82-03: The initial test of the siren system resulted in 3 of 20 sirens in Lake County not activating.
One siren out of 7 in Kenosha County failed to activate. The three sirens in Lake County which failed were CE-4, CE-5 and CE-8.
These have been repaired by the licensee's contractor, Whelen Engineering Company of Deep River, Connecticut. The defective Kenosha County siren,-WE-1, was removed due to its proximity to a commercial mink ranch. A Lake County siren, CE-6, was also removed for the same reason. A siren near the state line between Wisconsin and Illinois was transferred to Lake County control from Kenosha County. Thus siren, WE-5, is now CE-15.
Siren WE-2 was moved about one city block from a Wisconsin housing development because of complaints of the local residents there.
The present total number of sirens installed by the licensee within the 10 mile EPZ is as follows:
Lake County, Illinois
Kenosha County, Wisconsin
25 The inspector was given a current siren location map for all sirens within the 10 mile EP2 by a licensee's representative.
(Closed) Deficiency as identified in Appendix A and Section 6.2.1 of Emergency Preparedness Appraisal Report of August 26, 1981.
295/81-13-10; 304/81-09-10. Public information pamphlets or equivalent information have not been posted in public places, such as the Illinois Beach State Park and adjacent campgrounds.
Illinois Beach State Park management indicated to the licensee that they preferred an alternative method, namely the installation of two electronic sirens with public address capability.
These two sirens can be activated, rotated and can deliver a public message from a mobile controller console unit operated by a Park Ranger. These two sirens may be heard over the entire beach and campground area. A demonstration of the mobile unit's capability was made by the Park Superintendent for the inspector. A siren was rotated in 90 degree increments and a brief voice announcement delivered. This unit may be activated from the park office or from a park vehicle. These two electronic sirens are incorporated in the Zion site siren system.
The Lake County office encoder can also activate these two sirens, and when all the licensee's sirens are incorporated with the other county sirens, the whole system can be activated simultaneously.
