Public safety officials will conduct an annual test of the emergency sirens for the R.E. Ginna Nuclear Power Plant in Ontario this morning. Ninety-six sirens will sound for approximately four minutes between 9:30 and 10:00 a.m. within a 10-mile radius of the nuclear facility. The test will be audible in nearby communities including parts of Webster, Penfield, and near Irondequoit Bay, with potential additional single-siren tests scheduled throughout the day.


The purpose of the siren test is to check the effectiveness of the emergency notification system at the nuclear plant. Local residents are advised to disregard the sirens during this test. In the event of an actual emergency, instructions would be broadcast via radio and television.

The R.E. Ginna Nuclear Power Plant, positioned along the southern shores of Lake Ontario, is approximately 20 miles northeast of Rochester. It is one of the area’s critical infrastructures, with detailed emergency response plans detailed on the Monroe County website.
