And the states that are suing the EPA, per the article?
Liberal cesspools. There is much more abuse of clean air regs for global warming using particulates as an excuse, for example shutting down coal plants. All driven by the same liberals. The irony is that a coal plant puts out orders of magnitude less particulates per heat generated by the electricity than wood stoves do.
So they want to jack up electricity ("skyrocket" Obama said) and they realize that this will drive lots more people to wood stoves. So this is a step against that. All driven by liberals and zealots. Still, it would help that Forbes gets its facts correct.
