BALTIMORE—A Maryland man faces trial in a $9.1 million fraud case that is shedding light on problems in a renewable energy credits program run by the U.S. Environmental Protection Agency. Federal prosecutors accuse Rodney Hailey of Perry Hall of selling renewable fuel credits even though his company, Clean Green Fuel LLC, did not produce any renewable fuel. Instead, prosecutors say he pocketed the money and bought Ferraris and other luxury cars, as well as tractor-trailers, homes, jewelry and computers.
