2 Sites Transferring to Legacy Management Currently LM is responsible for LTS&M activities at over 37 facilities where active remediation has been completed and no continuing departmental mission exists LM will inherit 105 sites through 2009 Site transition is a systematic, comprehensive and inclusive process following the cleanup and closure process

3 DOE Criteria and Approach to Transition Seamless transition into or out-of LM depends on ability to establish a LTSM baseline and to develop and implement a Site Transition Plan Four Criteria for EM mission completion -short-term response activities are complete -long-term response measures are established and are operational and functional -necessary documentation in place -site is administratively transferred to another entity Started process to institutionalize LTS through new DOE Directives - DOE Order 430.1, Real Property Asset Management - DOE Order 450.1, Environmental Management System - DOE Order 413.3, Project Management

4 Legacy Management Goals Goals Long-term Surveillance and Maintenance Protect human health and the environment through effective and efficient long-term surveillance and maintenance Land and Asset Management Manage legacy land and assets, emphasizing safety, reuse, and disposition Work Force Restructuring and Benefits Management Support an effective and efficient work force structured to accomplish departmental missions, and assure worker pension and medical benefits Records and Information Management Preserve and protect legacy records and information

5 Long-term Surveillance and Maintenance & Site Reuse Long-term surveillance and maintenance activities include: Leachate collection and disposal Monitoring institutional controls Groundwater monitoring Erosion control LM staff has over 14 years expertise providing cost effective and efficient LTS&M Site Reuse LM is committed to managing legacy land and assets, emphasizing safety, reuse, and disposition

8 LTS&M Requires a System

9 Existing DOE Research $ Focused on Key LTS&M Functions DOE/SC maintains an diverse S&T program focused on environmental remediation LTS&M costs are generally low (averaging < 2% of the annual cleanup costs). Advances in technology would not significantly reduce cost on the scale that people are used to (i.e., EM cleanup). Ground water monitoring are highest LM costs Investment in new technology would depend on benefits realized from Improvements in cost-effectiveness Reduced restrictions on land use

10 BACKUP Capability Needs Identified by LTS Roadmap Nominal Funding and Functional Relationships of Capability Enhancements LTS&M life-cycle costs should be factored into cleanup decisions

11 Roadmap Process Identified Key Capabilities for LTS Contamination Containment and Control Alternate technologies that detoxify or immobilize contaminants at the source and reduce the volume of ground water needing to be treated. Cover and subsurface containment systems that mimic natural processes and accommodate environmental change. Models, natural analogues, and indicators that improve design, planning, decision making, monitoring, and maintenance. Technologies that significantly reduce the need for maintenance of containment systems. Decision Making & Institutional Performance Improved institutional credibility and community interaction to best maintain trust and confidence Continuous improvement of LTS decisions to sustain stakeholder support and reduce life-cycle costs. Institutional mechanisms that sustain and improve LTS. Monitoring and Sensors Validation of containment and safety system performance. Monitoring systems that can adapt to changes in knowledge of the geologic, hydrologic, chemical and biologic processes at the site. Improved multimedia monitoring capabilities. New methods that utilize advances in wireless, miniaturization, non-invasive, and remote interrogation technologies. Monitoring for surrogates and indicator parameters to reduce costs and improve accuracy. Information management systems that address validity, access, outreach, education, and visualization. Safety Systems & Institutional Controls Approaches to select standardized, risk-based safety systems that enhance efficiency of cost and operations. Criteria for analyzing data to ensure the integrity of security and access control systems. Technology that preserves site information for intergenerational continuity. Legal strategies and associated instruments to facilitate handoff of closed sites to stewards.
