Emissions

AEP has made significant long-term investments in environmental controls to reduce air emissions from its power plants. Between 2000 and 2017, AEP invested approximately $8.7 billion in environmental controls, primarily related to the Clean Air Act, that have significantly reduced emissions. From 2001 and including projections through 2017, AEP expects its emissions of mercury will be reduced by approximately 8,300 pounds, a reduction of approximately 87percent. Since 1990 and including projections through 2017, AEP expects its emissions of sulfur dioxide (SO2) and nitrogen oxide (NOx) will be reduced by approximately 1,460,000 tons and 560,000 tons, respectively, a reduction of approximately 94 percent and 89 percent, respectively.

Mercury emissions information is reported to the EPA under the Toxics Release Inventory program.
