How Constellation Energy manages coal ash

Constellation Energy adheres to specific guidelines in managing the coal ash its power plants produce:

• Before it is transported, coal ash is wetted and then carried in trucks that are covered to prevent leakage. Before the trucks leave the power plant, they are washed down to remove coal ash residue. Some of our ash is also transported in trucks designed to carry and fully contain dry powdery solids for recycling purposes.
• When wetted coal ash that is to be used as fill material, such as for road construction or mine reclamation, is delivered to a site, it is further wetted and compacted to prevent dispersion of dust.
• For coal ash to be used in reclamation, the facility must comply with new MDE regulations for placement of ash. Constellation Energy currently is not placing coal ash for reclamation in Maryland.
