An Environmental Protection Agency green energy program continues to lay a golden egg for con artists, as the Justice Department cracked down on yet another multimillion-dollar biofuels scam on Thursday.

“Two men have been indicted by a federal grand jury in Las Vegas for offenses involving the federal renewable fuel program that allegedly netted them more than $37 million,” Justice officials announced Thursday. To discuss the alleged crime, though, the press release first had to explain how the scam was made possible by EPA regulations.
