"When environmentalists press for the removal of river-choking old dams, George Howard can smell the money.
Howard's company is tearing down the Milburnie Dam on the Neuse River outside Raleigh, N.C. The 15-foot impoundment stretches 625 feet across the river, blocking fish runs and creating a deadly hydraulic trap that's drowned 15 swimmers.
Milburnie is Howard's third North Carolina dam removal. As with the other two, he will turn a profit using a tool called mitigation banking."
