New York's top court ruled Thursday, Dec. 15, 2011 that the state can require polluted Superfund sites to be returned to pre-industrial conditions, a win for environmentalists. The Court of Appeals says the state Department of Environmental Conservation can require polluters to restore sites to a level the judges call "complete cleanup."(AP Photo/DS, File)
