The United States Environmental Protection Agency (EPA) has released its much anticipated Boiler MACT rule for boilers, process heaters and industrial solid-waste incinerators. The rule was finalized on February 21, 2011, pursuant to a court order. Implementation costs associated with the new rule are approximately 50 percent less than those estimated in an earlier proposal issued last year.

Major changes include the addition of “work practice standards" instead of numeric-emission standards for small new boilers, limited-use boilers, and for periods of startup and shutdown. The EPA could not entertain public comments on the revised rule due to the court-imposed deadline. As a result, the EPA also simultaneously issued a Notice of Reconsideration of the final Boiler MACT rule, which will allow the public to comment on certain aspects of the final rule.
