"On Monday, a federal appeals court snatched that victory from the industry’s hands and sent EPA back to the drawing board. In a 2-1 decision, the court decided that the Clean Air Act did not give the EPA the authority to block the rule, and that its decision to do so was “unreasonable” as well as “arbitrary and capricious.” The rule — which Scott Pruitt and lawyers for the American Petroleum Institute are fighting to delay — cracks down on pollutants that tend to come from drilling operations. Pruitt wants to delay the rule for a year, even though his agency acknowledges that doing so will have a negative impact on the health of children living near oil and gas operations. One of the chemicals that the rule places tighter regulations on is benzene, which causes cancer."
