BUCHANAN - The Indian Point Energy Center tested its emergency siren system this morning.

The sirens sounded at full volume for about four minutes at 10:30 a.m. All 172 alarms were heard across Westchester, Rockland, Putnam and Orange counties.

Plant officials stress that the sirens were not a signal to evacuate. In an actual emergency, the sirens would sound to alert the public to tune in to a local EAS radio or television station for important information and direction.

The plant generates as much as 30 percent of the electricity used in New York City and Westchester County.
