THE LEGACY ASH RULE: CAN BENEFICIAL REUSE BE A SOLUTION? Authors Mr. Tom Kierspe - United States - The SEFA Group, LLC Abstract Tom Kierspe, P.E.1 1The SEFA Group, 219 Cedar Road, Lexington, SC 29073 KEYWORDS: Coal Ash Beneficiation, Beneficial Reuse, Encapsulated Reuse, Coal Ash Recycling, Thermal Beneficiation, Pond Reclamation, STAR Process, Stakeholders, CCP Impoundments, Characterization ABSTRACT On May 18, 2023, EPA proposed changes to the CCR regulations for inactive surface impoundments at inactive electric utilities, referred to as “legacy CCR surface impoundments”. With the final rule currently proposed to be issued April 2024, utilities are reevaluating these sites. Much of the CCR has been stored for decades exposed to the elements. Removal and landfilling remain an option but continues to draw negative attention and requires a minimum of three decades of management as well as the risk of new regulatory requirements in the future. As utility companies assess the potential to recycle CCR from these impoundments, each site is unique and needs a customized solution. Fortunately, the knowledge base for harvesting and beneficiating legacy CCR has continued to increase, reducing much of the uncertainty about the technical capability to beneficially reuse the CCR material. Now, based on years of commercial operating experience, there is more data on characterization, beneficiation, and performance of legacy CCRs that can serve to minimize overall cost, optimize removal timeframes, and increase operational efficiencies. In this presentation, the knowledge learned from active reclamation and beneficiation projects will be reviewed, as well as the potential benefits from incorporating this knowledge into future projects.
