Welcome to DOE's Office of Long-Term Stewardship web site! DOE established the Office of Long-Term Stewardship in 1999 to help coordinate and communicate long-term stewardship across DOE. Coordination is required because the majority of long-term stewardship activities are conducted at individual DOE sites and managed by a variety of programmatic offices both at headquarters and in the field. The establishment of the Office of Long-Term Stewardship reflects the importance of long-term stewardship to DOE's strategic objective to conduct its missions in a manner that protects human health and the environment. This website is designed to communicate the vision and mission of the Office of Long-Term Stewardship as well as to provide tools for planning for and executing Long-Term Stewardship at DOE sites.

The Fermi pile was built for the Manhattan Project in 1942 and achieved the world's first man-made, self-sustaining nuclear chain reaction. The caption on the marker reads: "CAUTION - DO NOT DIG Buried in this area is radioactive material from nuclear research conducted here 1943-1949. The burial area is marked by six corner markers 100 ft. from this center point. There is no danger to visitors. U.S. Department of Energy 1978."
