The anticipated industrial boiler Maximum Achievable Control Technology rule, or “IB MACT,” would regulate emissions of hazardous air pollutants, such as certain acid gases, organics, metals, and possibly other pollutants, from industrial boilers and would likely affect biomass boilers like the one planned for Plant Mitchell.

“Georgia Power is committed to furthering the development of renewable energy in Georgia,” said Jeff Burleson, Georgia Power’s director of Resource Policy and Planning. “We’re disappointed to have to delay this large biomass project and the benefits it can deliver. However, by delaying capital spending on the project we’re significantly reducing the cost risk to customers.”

Georgia Power had originally planned to begin retrofit construction at Plant Mitchell in April 2011 with the unit becoming operational in June 2012. A new project schedule has yet to be determined.
