Award Represents One of the Largest and Longest Term Projects in Company History

Includes Excavation of Approximately 4.3 Million Cubic Yards of Coal Combustion Residuals from Three Ash Ponds to Support Ongoing Beneficiation Activities and Facilitate Future Pond Closures

Charah^® Solutions, Inc. (NYSE:CHRA) ("Charah Solutions" or the "Company"), a leading provider of environmental services and byproduct recycling to the power generation industry, today announced that it has been awarded a multi-pond ash pond excavation contract from a long-term southeastern utility partner. The project, which is one of the largest and longest in duration in Company history, is scheduled to start in Q3 2022 and is expected to take approximately 9 years to complete.

Charah Solutions' Remediation & Compliance Services at the site will include the excavation of approximately 4.3 million cubic yards of coal combustion residuals (CCRs) from three ash basins to facilitate future pond closures. An estimated 3.9 million cubic yards, or 90% of the total CCRs removed, will be earmarked for beneficiation and eventual recycling into the concrete industry serving as a sustainable replacement for Portland cement. The remaining 430,000 cubic yards of comingled CCR and soil materials will be excavated for off-site disposal into lined landfill facilities. Charah Solutions' Remediation & Compliance work on this long-term project will incorporate geotechnical engineering, global stability analysis, engineered design excavation, water management, and site infrastructure development.
