Unconventional oil and gas production (or "fracking") has generated new wealth, new jobs, and new sources of energy for many Americans. But fracking has also generated local congestion and pollution problems, and some believe that it creates significant risks for state fresh water supplies or global climate change. In many states, localities opposed to fracking are trying to ban the practice or impose long moratoriums on it within municipal limits, notwithstanding statewide political support for fracking. The tensions between state-level energy policies and local restrictions raise legal questions about when statewide energy regulations should preempt local efforts to restrict fracking using local powers over land use. Earlier this month, the Colorado Supreme Court handed down two new and important preemption decisions, City of Fort Collins v. Colorado Oil & Gas Association, and Longmont v. Colorado Oil & Gas Association. Our experts discussed both cases, their significance in Colorado, and their implications for fracking and preemption law elsewhere in the United States. -- Featuring: Prof. Eric R.
