N.C. Clean Smokestacks Act 2002 - Clean Smokestacks Act signed into law Developed cooperatively with Gov. Easley and
legislative, regulatory, environmental and business leaders
Significantly cuts NOx and SO2 emissions from utility-owned coal-fired power plants
Technologies will also reduce mercury emissions by more than two-thirds statewide
Model for other states to improve air quality

How Does a Scrubber Work?
A slurry of finely ground limestone (CaC03) is sprayed into a reaction tower, which has flue-gas flowing counter-current to the spray. The SO2 in the gas reacts with the limestone, removing 97% of the S02 and making CaS04 (gypsum).

A balanced solution
Increasing demand for electricity Commitment - and obligation - to provide reliable and
affordable electricity Cannot rely on just one approach – requires a
balanced solution Efficiency & conservation Supporting alternative energy technologies Investing in new power plants

Planning for the future
Considering new nuclear generation in Carolinas and Florida
Potentially plan to file two combined licenses (COL)s with the Nuclear Regulatory Commission by 2008
Community involvement is key COL applications do not commit company to building
plants
