Assessing CCR Beneficiation Options for CCR Pond Closures Authors Mr. Kelly Babichuk - United States - Ashcor Mr. Dale Evans - United States - RECON Abstract A fundamental tenet for waste regulation under RCRA was to reduce land disposal. Thus, the available provision for beneficial re-use of CCR using beneficiation processes represents a unique opportunity for utilities to off-set the life-cycle expense otherwise recognized for the associated regulatory liability tails. With the steadily declining production of fly ash, the increased prominence of using beneficiated ash has tremendous value across the construction industry. Specifically, single-source solutions have been developed that directly focus on using ash beneficiation to offset the life-cycle cost for liability management and facility closure. Properly configured, these beneficiation solutions may offer utilities revenue stream to off-set their long-term liabilities using existing ash inventories. In particular, utilities may substantially benefit from the time-based process employed across a period of years due to the steadily increasing value of beneficiated ash materials. In considering the life-cycle value of regulatory liabilities carried forward, recent valuation efforts have demonstrated that total life-cycle costs for closure-in-place are rapidly approaching those associated with clean closure processes. Instances of proximate equivalency may thus drive more projects away from closure-in-place by providing clarity of cost containment as well as the long-term benefits accrued by utilities for clean closure. To understand the true financial benefits a beneficiation process may offer, an example pro forma is presented to support development of the information required to understand the applicable site conditions, field operations, beneficiation processes, and production rates, as the basis for defining life-cycle costs and management options. This paper provides a synopsis of the most critical aspects for analysis to develop such pro forma to assess the financial efficacy of beneficiation for the clean closure of CCR impoundments.
