The Federal District Court of Wyoming cleared the way for additional challenges to the U.S. Bureau of Land Management’s (BLM) authority to impose regulations on fracking practices.

At the center of the dispute is who has the ultimate authority to regulate fracking practices. States are claiming that an additional layer of federal regulation is unnecessary. North Dakota asserts that the BLM overstepped its authority by trying to interfere with the state’s current and comprehensive rules and standards. They claim these additional rules aren’t necessary because the EPA has already granted authority to the states to monitor and protect underground water sources.
