Leading the way in coal combustion product use

Since the mid-1980s, we have steadily reduced the amount of coal combustion products (CCPs) that are landfilled, even when faced with increasing amounts of CCPs from new generating plants and air quality control systems added to reduce emissions at older plants. Over the last several years, we beneficially used nearly all of the 8.8 million tons of CCPs produced at our power plants. The national average is around 45 percent.

We continue to be a leader in developing new uses for our CCPs, including use of fly ash to improve the performance of asphalt pavement (“ASHphalt”) and gypsum to reduce nutrient runoff from agricultural fields.

Our efforts are not limited to the daily production of CCPs. Over the past few years, we have recovered landfill ash for use on the I-94 reconstruction project, reclaiming valuable landfill capacity and conserving quarried materials for use by future generations.
