Under a settlement agreement with community and environmental groups and Duke Energy that ends the appeal litigation, Duke Energy will move forward with excavation plans at the Roxboro Power Station and dispose of ash in a lined onsite landfill.
Duke Energy submitted a closure plan by the December 31, 2019 deadline, as required by Coal Ash Management Act (CAMA) of 2016 and in accordance with the agreement. DEQ has approved the closure plan. Access historical Public Meetings.

The Coal Ash Management Act (CAMA) provides three principal closure pathways:
- Option A: closure in a manner allowed for a high-risk site, such as excavation and disposal in a lined landfill
- Option B: closure with a cap-in-place system similar to the requirements for a municipal solid waste landfill
- for this option, there is a further requirement that upon full implementation of the closure plan, the groundwater must be in compliance with the 2L standard at the compliance boundary of the impoundment.
- Option C: closure in accordance with the federal CCR rule adopted by the EPA.
After conducting a rigorous scientific review of Duke Energy’s proposals for Allen, Belews, Cliffside/Rogers, Marshall, Mayo and Roxboro facilities, and conducting public listening sessions in impacted communities, DEQ has determined Option A is the only closure option that meets the requirements of Coal Ash Management Act to best protect public health and the environment. Coal ash must be excavated and moved to a lined landfill.
