What TVA is doing about emissions at Colbert

TVA has taken a number of steps to make the efficient generation of power at Colbert as clean as possible:

• Ash from the burned coal is removed and used commercially when possible. The remaining ash is disposed of onsite.
• Four of five units burn low-sulfur coal to limit emissions of sulfur dioxide (SO₂).
• Low-NOx burners limit emissions of nitrogen oxides (NO_x), which contribute to the formation of ozone and acid rain.
