CCR Rule Compliance Data and Information

Closing ash ponds safely and permanently

• The company is treating and removing all water from the pond.
• Material will be excavated and moved farther away from waterways, creating buffers of up to 750 yards from the Mobile River – a distance in some places longer than seven football fields.
• The size will be reduced by 267 acres, or about 45 percent.
• Using advanced engineering, Alabama Power will construct a redundant dike system as part of the plant’s increased, robust flood-protection measures.
• In addition to the redundant dike system, Alabama Power will construct a subsurface retaining wall around the entire consolidated footprint to provide further groundwater protection. The site benefits from a unique, natural solid clay layer that extends up to 28 feet below the ash pond. The retaining wall will extend below ground and tie into the clay layer to effectively seal the material in place.
• Additionally, an internal drainage system will be constructed around theperimeter of the consolidated footprint to accelerate the removal of water.
• The company will install a specially engineered barrier over the material to keep it safely in place.
• Storm water systems will be added to manage rainwater runoff.
• Alabama Power will monitor groundwater around the facility for at least 30 years to ensure ongoing protection of water quality.
