Converting to dry storage

  • We are moving our power plant materials to dry storage.
  • We are eliminating the use of ash ponds and other storage impoundments.
  • These projects meet new state water quality standards and the U.S. EPA’s Coal Combustion Residuals Rule.

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

  • Projects of this scope and size require years 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 storage, and a new dry storage facility is under construction at Trimble County power plant.

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