LM’s mission is to fulfill the Department of Energy’s post-closure responsibilities and ensure the future protection of human health and the environment. DOE has taken significant environmental cleanup steps, and we are protecting the outcome of that work with long-term stewardship.
LM carries out its mission within the communities that made sacrifices for the nation during one of the most critical periods in our country’s history. This is accomplished through surveillance and maintenance, records management, an effective and efficient workforce, benefits continuity, asset management, and community engagement.
