Abstract/Additional Information | Abstract Only - The closure of mine processing and waste disposal facilities is both a regulated activity and a potential source of corporate liability. All facilities must be designed and operated to satisfy relevant environmental regulations; however the authors' experience in preparation, submittal, defense and obtaining regulatory approval for implementation of closure related activities indicates that few are designed, and even fewer operated to facilitate closure. This paper discusses both the conceptual framework for closure oriented design and operation, and several specific design and operational elements that are key to characterizing closure components, and providing data that can be used to defend closure design and implementation. Discussion will be based on experience obtained from case studies, and include: Mass Stability (static and seismic) Engineering Characteristics Operating and Closure Water Balance Operating and Closure Water Chemistry Solids Chemistry Receptor Characterization Potential of Source to Degrade State Water Pathway Characterization Potential for Pathway to Mitigate Discharge Disposal and Treatment Options for Post-Operational Effluent Final Closure Designs Operating, Closure, and Post-Closure Monitoring |
