Lynn L. Bergeson and Chris R. Bryant, “EPA Issues Final Rules for Boilers,” Chemical Processing, April 2011.

The U.S. Environmental Protection Agency (EPA) reports that more than 200,000 boilers, process heaters and incinerators will be impacted by a set of Clean Air Act regulations issued on February 21, 2011. Since EPA first proposed the Maximum Achievable Control Technology (MACT) rules in April 2010, several industry sectors have argued the costs of implementing the rules would pose an unreasonable burden on businesses. In response to this criticism, EPA revised the rules in a manner that it believes cuts the cost of implementation by about 50%.
