  • NNSA Announces Its Intent to Prepare a Programmatic Environmental Impact Statement for Plutonium Pit Production and Public Scoping Meetings 

    On Friday May 9, 2025, the National Nuclear Security Administration (NNSA) announced its intent to initiate a National Environmental Policy Act of 1969 (NEPA) programmatic environmental impact statement (PEIS) process to ensure NEPA compliance for the production of plutonium pits in support of NNSA's Stockpile Stewardship and Management Program.  The PEIS will evaluate the programmatic environmental impacts of producing pits at the Congressionally mandated rate (and potentially other reasonable rates) using various single site and multi-site alternatives; associated activities at other NNSA sites; and associated waste management and transportation activities.

    DATES: NNSA invites all interested agencies (Federal, State, Native American Tribes, county, and local), public interest groups, businesses, and members of the public to submit comments on the scope, environmental issues, and alternatives for consideration by NNSA in the draft PEIS until July 14, 2025. Comments received after this date will be considered to the extent practicable. NNSA will hold two virtual public scoping meetings for the proposed PEIS as follows:
