DOE National Long-Term Stewardship Working Group (LTSWG)

The U.S. Department of Energy (DOE) National Long-Term Stewardship Working Group (LTSWG) is a cross-program team established by the DOE Office of Environmental Management (EM), Office of Legacy Management (LM), and National Nuclear Security Administration (NNSA) to address national and crosscutting site-level Long-Term Stewardship (LTS) activities and issues. DOE organizations have varying Long-Term Stewardship (LTS) responsibilities. While EM performs LTS at remediated locations within active EM cleanup sites, and NNSA performs LTS at remediated locations at active NNSA sites, LM performs LTS only at remediated sites that no longer have an active mission. The Working Group will collaborate on high-priority LTS topics of interest, align practices, share lessons learned, leverage contacts, and make recommendations to resolve issues. LTSWG will foster communication across DOE offices and with other federal agencies, states, tribes, stakeholders, and communities.

Mission

The mission of LTSWG is to develop tools and provide recommendations to DOE leadership to foster a collaborative, consistent approach to LTS planning and execution across the DOE enterprise. This is accomplished through information sharing regarding key programmatic elements, such as the status of LTS planning and implementation at individual DOE sites, best management practices, and lessons learned. Although LTSWG may provide recommendations, these recommendations are advisory only and decision-making regarding cleanup strategies and long-term institutional controls rests with the respective DOE offices and sites that hold the requisite authority. DOE sites will remain the primary points of contact with local stakeholders.
