"First, where do you read that in Steve Miller's quote?"
The new EPA rules are about reducing air pollution. The head of the coal industry front group doesn't even mention air pollution.
And if he's the head of something called The American Coalition for Clean Coal Electricity then what is his problem with making coal cleaner?
He doesn't say the new regs are too strict. He doesn't offer any suggestion to loosen them. He doesn't like the idea of new regs at all.
Coal industry lobbyists have a job to do and he's doing his.
