2.0 NEWBURYPORT ALTERNATE ALERTING SYSTEM The Newburyport public. alerting system for Seabrook Station has been designed to provide coverage to essentially 100 percent of the Newburyport Rev.
1 population within the Plume Exposure' Pathway Emergency Planning Zone.
This system meets the requirements of 10.CFR 50.47 and Appendix E (Reference 1) and is consistent with guidance contained in NUREG-0654/
FEMA-REP 1, Revision 1 and Appendix 3-(References 2 and 3).
The City of Newburyport is located approximately 6 miles from Seabrook Station with the closest border 5 miles south of the plant. Newburyport has an approximate population of 16,400.
Principal highways in Newbury-l port include Interstate 95, U.S. Routes 1 and 1A and State Route 113.
Special facilities include a public school system with approximately 3300 students, a general hospital, long-term care facilities and day care center / nurseries.
The Seabrook Prompt Notification System is comprised primarily of fixed sirens strategically positioned throughout the Plume Exposure Pathway EPZ.
A total of 147 fixed sirens had been installed in and around com-munities in New Hampshire and Massachusetts. Twelve fixed sirens are located in the community of Haverhill, which is outside the EPZ.
In September, 1987, Newburyport municipal authorities removed six of eight sirens providing alerting coverage to the city and refused permission for the remaining two sirens to be used for emergencies at the Seabrook i
Station. Without the eight sirens, existing sirens in neighboring com-munities (rovide overlapping siren tone coverage for approximately 60' percent of the area covered by the original eight sirens.
