But some people say Indian Point is a disaster waiting to happen.

“The Indian Point Power Plant is located near the intersection of two earthquake faults. Nuclear energy cannot be safe. Plutonium can contaminate the environment for hundreds of years. Studies show that New York City could not be evacuated in time,” protester Tom Syracuse said.

One person said on a YouTube post that the plant’s frequent siren tests are leading residents to believe that everything in the future could just be a test and not a real emergency.

“If you have to test them so much to see if they work right, how will people react when there’s an actual problem?” the man said.

One of the problems people fear could be an earthquake like the one in Japan.

There are some fault lines near the plant, but geological experts say the chance of a earthquake happening hear are slim.
