CHARLOTTE, N.C. -

Duke Energy received a revised air permit for the new, state-of-the-art Cliffside Unit 6 this afternoon from the North Carolina Department of Environment and Natural Resources, Division of Air Quality (DAQ), which designates that the unit is a minor source of hazardous air pollutants.

This designation by the DAQ confirms that the new Cliffside Unit 6 will have among the strictest, most effective air emission controls available to protect public health and the environment. According to the DAQ, “the new monitoring requirements include enhanced coal testing, more frequent and extensive analysis of stack emissions, and increased monitoring of scrubber operations.”

The revised permit includes new conditions that restrict the unit’s hazardous air pollutants (HAP) to ensure they are less than 10 tons per year for any HAP and less than 25 tons per year for any combination of HAPs. The revised permit also includes the same stringent limits as the original permit for sulfur dioxide, nitrogen oxide, mercury and other emissions, along with the additional conditions.

The Cliffside modernization project, including engineering, procurement, construction and start-up activities, is more than 30 percent complete. Given the announcement earlier this week that North Carolina’s unemployment rate has climbed to nearly 10 percent, Duke Energy is proud to be constructing one of the cleanest coal-fired plants in the nation while employing approximately 850 workers at the site.

Once the new unit comes on line in 2012, Cliffside Unit 6 will generate more than double the electricity for customers than the current facility, while significantly reducing emissions. In addition, Duke Energy has committed to retire 1,000 megawatts of older, less efficient coal-fired units in North Carolina as a result of this modernization project between 2012 and 2018.
