The National Environmental Policy Act (NEPA) is the landmark environmental law which requires executive agencies to give the public the opportunity to formally review and comment on major federal proposals. These talking points outline the history of the Department of Energy’s NEPA compliance on its various proposals concerning the production of plutonium pits (the fissile cores of nuclear weapons). The conclusion is that DOE’s semi-autonomous National Nuclear Security Administration (NNSA) is legally required to prepare a supplemental programmatic environmental impact statement (PEIS) on its current plan to expand plutonium pit production.
There are at least three reasons why NNSA must complete a supplemental programmatic environmental impact statement for expanded plutonium pit production:
1) Implementing regulations for the National Environmental Policy Act stipulate that “DOE shall prepare a supplemental EIS if there are substantial changes to the proposal or significant new circumstances or information relevant to environmental concerns…” 10. C.F.R. § 1021.314
2) As precedence, since 1996 there have been five programmatic environmental impact statements related to pit production and its expansion. It is legally unlikely that NNSA could implement its current plan to expand plutonium pit production without a new supplemental PEIS.
3) Now that NNSA is planning to produce more than 50 pits per year (or more than 80 pits under multiple shift operations), it is obliged by the 1998 court order to prepare a new PEIS.
