At a news conference in December, Mitchell described the plant’s technology to control emissions as “state of the art.” Mitchell also said he “will be very surprised if (EPA officials) have any problem with what we have done.”
But last week, the Environmental Protection Agency sent the agency a letter questioning two of the proposed emission levels granted by the permit and whether they violate the Clean Air Act. The new analysis compared emissions of four pollutants from the almost 700 coal-fired generating units in the country with the emission levels listed in the Sunflower permit. The report found that the Sunflower permit did not compare well in two areas:
•At least 669 coal-fired generating units have lower emissions of particulate matter than the current Sunflower permit allows.
•At least 321 coal-fired generating units have lower emissions of mercury than the Sunflower permit allows.
The permit compared better in two other areas, but the EPA is questioning whether the permit is adhering to new federal rules on those. According to the report:
•At least 53 coal-fired generating units have lower emissions of sulfur dioxide than the Sunflower permit allows.
•At least 18 coal-fired generating units have lower emissions of nitrogen oxides than the Sunflower permit allows.
