News release: "The U.S. Environmental Protection Agency (EPA) today announced a final rule to address greenhouse gas (GHG) emissions from the largest stationary sources, while shielding millions of small sources of GHGs from Clean Air Act permitting requirements. The phased-in, common-sense approach will address facilities like power plants and oil refineries that are responsible for 70 percent of the greenhouse gases from stationary sources that threaten American’s health and welfare."
