• Environmental Risk Transfer Services Leader to Demolish Existing Power Plant, Close Ash Landfill, Remediate Site and Redevelop Property in a Sustainable Manner
• Charah Solutions' Growing Environmental Risk Transfer Portfolio Proves Beneficial to Utility Partners, Shareholders, Local Communities and the Environment

Charah^® Solutions, Inc. (NYSE:CHRA) (the "Company"), a leading provider of environmental services and byproduct recycling to the power generation industry, today announced that it has completed the full acquisition of the Cheswick Generating Station, the Lefever Ash Landfill and the Monarch Wastewater Treatment Facility from GenOn and will begin environmental remediation and sustainable redevelopment of the Pennsylvania properties immediately. The asset purchase agreement with GenOn was signed in December 2021, and the full transfer was completed today, April 6, 2022. The Cheswick Generating Station ceased electrical generation operations on March 31, 2022.

As part of this agreement, Charah Solutions, through three companies related to its subsidiary, Charah Environmental Redevelopment Group, LLC (CERG), has acquired the properties from GenOn Holdings, LLC, which consist of:

• The retired Cheswick Generating Station, a 565 MW coal-fired plant previously operated by GenOn, located in Springdale, PA, outside of Pittsburgh and along the Allegheny River. The 56-acre primary generating station site, along with an adjacent 27-acre parcel, consists of an operating rail line, a coal yard, bottom ash emergency and recycle ponds, waste ponds and a coal pile runoff pond, coal delivery equipment, and an ash handling parcel. CERG will be responsible for the shutdown and decommissioning of the coal power plant, the remediation of the two ash ponds and performing all environmental remediation and redevelopment work at the site. The shutdown of the Cheswick Generating Station provides a reduction of more than 1.0 million tons of CO2 per year from entering the atmosphere for the reduction of greenhouse gasses.
• The Lefever Ash Landfill located three miles northwest of the Cheswick Generating Station in Cheswick, PA. The 182-acre site, including the 50-acre landfill facility, is currently operating and provides disposal of coal combustion residuals (CCR) and residual waste from the Cheswick Generating Station under an active solid waste permit. CERG will be responsible for the closure design, remediation closure work and post closure monitoring of the landfill.
• The Monarch Wastewater Treatment Facility located on seven acres in the Borough and Township of Springdale in Allegheny County, PA. CERG will be responsible for day-to-day management and operations and compliance with all applicable environmental regulations.

CERG has retained Avison Young to provide real estate advisory, development, and brokerage services to oversee the redevelopment of the property and future sales of the remediated properties. CERG plans to redevelop the properties in an environmentally conscious manner that will expand economic activity and benefit the surrounding communities through job creation, promotion of industry, and support of the tax base while enabling the site to provide the best potential use for the community moving forward, all while sustainably remediating the site for the betterment of the community. The existing power plant will be demolished, and potential redevelopment uses for the properties include renewable energy and battery storage options that utilize the existing transmission system, re-use of the switchyard, transportation and logistics that utilize the river shipping assets, and other potential industrial uses.

This acquisition of the Cheswick Generating Station, the Lefever Ash Landfill and the Monarch Wastewater Treatment Facility is the Company's fifth major Environmental Risk Transfer (ERT) project and the second major project with GenOn. The Company announced the acquisition of GenOn's Avon Lake Generating Station and adjacent property in June 2021 and completed that acquisition on April 4, 2022.

As a leader in environmental remediation and risk transfer services to the power generation industry, Charah Solutions provides a proven ERT services model that delivers compelling value to utility partners, shareholders, local communities and the environment. In March 2022, the Company announced the sale of 100% of the real property acreage at the former Gibbons Creek Steam Electric Station and Reservoir in Texas. Charah Solutions is also currently working to complete another ERT project at the former Consumers Energy B.C. Cobb Generating Facility's ash ponds near Muskegon Lake in Muskegon, MI, which was acquired by the Company in April 2020. This ERT project involves the full remediation of the existing ash ponds while further advancing the wetlands along the eastern shore of Lake Michigan and includes the beneficial recycling of 650,000 cubic yards of ash materials and sustainably repurposing of the property.

With approximately 240 existing coal-fired power plants in the U.S. expected to be decommissioned over the next 10 to 15 years, Charah Solutions is ideally positioned to capitalize on its innovative ERT services model to partner with additional utilities to perform the shutdown, remediation and redevelopment of these plant properties for years to come.

"This is the end of an era for Cheswick, and the retirement of this facility reflects the changes occurring in our nation and around the world," states David Freysinger, GenOn CEO. "We are delighted to reach agreement with Charah Solutions. This transaction will bring Charah Solutions' expertise to bear in redeveloping the property for the benefit of the community."
