"Since Barack Obama was sworn in as President in 2009, the Environmental Protection Agency (EPA) has proposed and promulgated numerous regulations implementing the pollution control statutes enacted by Congress. Critics have reacted strongly. Many, both within Congress and outside of it, have accused the agency of reaching beyond the authority given it by Congress and ignoring or underestimating the costs and economic impacts of proposed and promulgated rules. The House conducted vigorous oversight of the agency in the 112th Congress, and approved several bills that would overturn specific regulations or limit the agency's authority. Similar action may occur in the 113th. Particular attention is being paid to the Clean Air Act, under which EPA has moved forward with the first federal controls on emissions of greenhouse gases and also addressed emissions of conventional pollutants from a number of industries; congressional scrutiny has focused as well on other environmental statutes and regulations implemented by EPA. Environmental groups and others disagree that the agency has overreached, and EPA states that critics' focus on the cost of controls obscures the benefits of new regulations, which, it estimates, far exceed the costs. It maintains that pollution control is an important source of economic activity, exports, and American jobs, as well. Further, the agency and its supporters say that EPA is carrying out the mandates detailed by Congress in the federal environmental statutes. This report provides background information on EPA regulatory activity during the Obama Administration to help address these issues. It examines 46 major or controversial regulatory actions taken by or under development at EPA since January 2009, providing details on the regulatory action itself, presenting an estimated timeline for completion of the rule (including identification of related court or statutory deadlines), and, in general, providing EPA's estimates of costs and benefits, where available. The report includes tables that show which rules have been finalized and which remain under development."
