A federal judge in Wyoming has temporarily blocked implementation of new rules governing fracking on federal lands.

The new rules would require the disclosure of fracking chemicals and more mechanical integrity testing for wells, among other things. But U.S. District Court judge Scott Skavdahl argues in the injunction that federal agencies cannot regulate fracking.

An unfolding court case might change how Powder River Basin coal is taxed in Montana. Last week, a Montana district court heard oral arguments in a lawsuit pitting Cloud Peak Energy against the state.

The state is asking for $3.4 million in back taxes, arguing that Cloud Peak underpaid between 2005 and 2007 by selling to an affiliated company at below-market value.
