With no room to put snow, Eastern waterways beckon

It's allowed in emergency situations, and some officials staring at massive snow mountains in densely populated areas of the winter-walloped Northeast say that time is now, even as others warn dumping snow in water comes with big problems.

"There's a lot of stuff in this snow that if I isolated it and threw it in the river, you'd have me arrested," said John Lipscomb of the New York-based environmental group Riverkeeper.

The federal Environmental Protection Agency doesn't directly regulate dumping snow but recommends against dumping it in water. It also urges state and local governments to include snow disposal restrictions in storm water management plans. Some states and municipalities restrict dumping snow into waterways out of fear of harming water life and polluting drinking water. Massachusetts is one of them.
