Independent Experts

Safely managing coal ash in a changing climate

The scientific studies of coal ash and our basins, dam safety inspections, emergency planning, ongoing environmental monitoring efforts and more – performed by the company and outside experts – are how we protect the environment and the communities we serve.

This information shapes operational procedures, site-specific ash basin closure plans, and projects to enhance climate resiliency. Our approach addresses the operational, environmental, strategic and financial risks associated with effectively managing coal ash today and for decades after basin closure.

All closure plans are engineered to improve groundwater and ensure the long-term safety of ash storage. 

Independent experts

Independent experts, including a national advisory board comprised of the foremost national experts on coal ash, engineers, scientists and dedicated teams at Duke Energy, have spent thousands of hours studying data, building enhanced groundwater and surface water protection programs and engineering closure solutions that protect people and the environment in a cost-effective manner.

The National Ash Management Advisory Board (NAMAB) is led by Dr. John Daniels, P.E., a former program director at the U.S. National Science Foundation and current professor and chair of the Department of Civil and Environmental Engineering at the University of North Carolina at Charlotte.

Working with Duke Energy engineers and scientists, NAMAB developed a set of guiding principles for safe basin closure. These principles provide a sustainable framework for promoting recycling, protecting groundwater and minimizing impacts to local communities and the environment, while safely anticipating major storms, flooding and even seismic events.
