The Land Disposal Restrictions (LDRs) of the Resource Conservation and Recovery Act (RCRA) are the critical technical standards for the establishment of compliance plans and schedules for the treatment and disposal of mixed waste within the Department of Energy Complex. The LDRs specify treatment standards that must be met before a hazardous waste can be disposed of in a land disposal facility. Criteria for the final disposal of mixed waste, availability of permitted treatment and disposal capacity, characterization of the mixed waste, and availability of financial resources are some of the important elements in the uncertainties in establishing technical performance, cost, and schedules for compliance. Often, uncertainties cannot be analyzed rigorously because the available waste characterization and technical performance data are limited; additionally, technical and economical parameters for mixed waste management are not well established. This situation has created the opportunity for the development and the application of affordable computing tools to support the planning and execution of mixed waste management projects. This paper describes a conceptual framework for the management of uncertainties using risk as a key driver for project control.
