Coal ash at the Chesterfield station was originally managed in the Lower and Upper Ponds where it was wet sluiced from the station prior to settling out and managed in long term storage. Chesterfield Power Station underwent a number of waste water and environmental improvements in 2017, including a transition from wet sluicing coal ash to a dry ash management.

New ash produced is taken to an onsite state of the art landfill permitted by the Virginia Department of Environmental Quality to receive and manage dry coal ash. The Lower and Upper ponds will be closed in accordance with all applicable federal, state and local environmental regulations and once necessary permits are obtained.

A byproduct is generated from scrubbers used to clean air emissions. It is primarily composed of calcium sulfate or gypsum, which is beneficially reused as wallboard quality gypsum.
