When a mountaintop gets bulldozed to extract coal, those bulldozers have to do something with all that rock. That rock is called the “spoil”. Without environmental protections in place, coal mining companies dump the spoil wherever, often burying streams and affording at least the possibility of nasty things leeching into groundwater. A 1983 rule established a buffer zone for streams. The Bush Administration did away with this rule in late 2008. The Obama Administration re-established a safe buffer zone for streams. This bill challenges that buffer zone.
