Too bad for the western states that allowed themselves to be colonized by the central government. Great for private land owners, who will reap the rewards of selling leases to oil and gas companies . With federal land out of the picture, prices for private land leases will rise...and the price will be paid by consumers in higher bills for gasoline and natural gas.
For now, at least. Read the first sentence -- rules could set a standard such that application to all lands could follow. Sort of like that frog in the pot analogy.
