The House just passed a bill that would eviscerates EPA coal ash regulations. Why are those regulations necessary? See here and here if you want to review what a coal ash spill can do and what the health effects of being near this stuff can be. You want coal ash heavily regulated.
A Republican president in 2017 would sign this into law. Given that the House is going to remain with the GOP and the Senate probably will, this is what Republican governance would look like. Coal ash pollution for all!
