The U.S. Environmental Protection Agency has issued final Clean Air Act standards for boilers and solid waste incinerators and cut the cost of implementing these regulations by 50 percent from an earlier proposal.

There are about 13,800 boilers at large sources including refineries, power plants and other industrial facilities. EPA estimates that implementation cost savings have been reduced by $1.87 billion from the proposed standard.

The rules require boilers follow practical, cost-effective work practice standards to reduce emissions of mercury, soot, lead and other particles from about 200,000 boilers at large and small producers, including power plants. The agency was also able to lower the cost of emission control technology by 50 percent.

EPA proposed the rules in April 2010 in response to a September 2009 court order to cut emissions.

EPA will work with the Department of Energy and large coal and oil-fired power plants to help them identify clean energy strategies that will reduce emissions and make boilers run more efficiently and cost-effectively.
