The Office of Surface Mining has proposed a new rule for regulation of coal mining they say will take advantage of new science to protect the environment, while still allowing coal mining. However, coal industry representatives say the Stream Protection Rule is a rule that seeks to fix a problem that doesn’t exist. The rule would adjust monitoring requirements when it comes to groundwater pollution. The Colorado Mining Association’s Stuart Sanderson says the rule is unnecessary and duplicative to Colorado’s regulations. The public comment deadline was last week, and the association says the 60 day period was too short a time to gather that input. Denver was the only city in the west that federal regulators gathered public input on the rule.
