FILE - This May 19, 2009 file photo provided by the Sierra Club shows the environmental group's executive director, Michael Brune. As the oil and gas drilling method known as hydraulic fracturing, or "fracking," mobilizes thousands around the country both for and against the process, industry and some environmental groups in Illinois have come together to draft regulations both sides could live with. Brune says it is possible that there will be more collaboration to establish better safeguards for air, water and climate, “but as we learn more about the true impacts of gas, and more and more communities are questioning whether we need it at all ... we'll definitely see more conflicts.” (AP Photo/Sierra Club, Lori Eanes, File)
