CCR Rule Compliance Data and Information
On April 17, 2015, the U.S. Environmental Protection Agency released a final rule for management and disposal of Coal Combustion Residuals (CCRs) from electric utilities. In 2018 the Alabama Department of Environmental Management issued its state CCR rule, which closely tracks the federal rule.
Closing ash ponds safely and permanently
Numerous advanced engineering technologies go above and beyond closing in place.
THE CLOSURE PROCESS
Advanced treatment ensures the water meets environmental standards before being removed.
Excavate and reduce
Material is carefully excavated and moved farther away from rivers and waterways, creating protective buffers while reducing the size of each pond.
Using advanced engineering, additional protections, such as redundant dike systems and other structures, are being constructed for increased, robust flood protection.
Permanent closure and ongoing monitoring
Finally, a specially engineered barrier is constructed over the material to keep it safely in place. Ongoing monitoring ensures water quality around the closed site is protected.
