Converting to dry management

  • We are moving our CCRs to dry management, which reduces any risk of groundwater contamination.
  • We are eliminating the use of ash ponds and other wet surface impoundments.
  • These projects meet new state water quality standards and the U.S. EPA’s CCR Rule.

We first embraced the idea of dry management for our CCRs in 2008, well before the EPA’s CCR Rule. 

  • Projects of this scope and size require years – up to 12 years in some cases – for planning; contracting; local, state and federal regulatory permitting; and construction.   
  • Already, our E.W. Brown, Ghent and Mill Creek power plants operate using dry CCR handling and storage management, and a new dry storage facility is nearly complete at our Trimble County power plant.

Once processed, the dry materials will be managed on site at our power plants or beneficially used offsite for materials such as concrete, wallboard or fertilizer.
