FILE - In this Dec. 9, 2014 file photo, anti-fracking protesters rally outside the U.S. Bureau of Land Management (BLM) in Reno, Nev., during the auction of oil and gas leases for energy exploration that critics say poses a threat to fish, wildlife and groundwater. Environmentalists filed an anti-fracking lawsuit in Nevada to block an effort to expand oil and gas drilling on federal land. Two national conservation groups say the Bureau of Land Management is reversing course from policies it enacted in the final weeks of the Obama administration. (AP Photo/Scott Sonner, File)
