Four public interest groups said Tuesday they are suing the federal government, seeking to stop construction of multi-billion dollar nuclear production factories in South Carolina and New Mexico that would make components for new atomic weapons.

Savannah River Site Watch, Nuclear Watch New Mexico, Tri Valley CARES and the Gullah Geechee Sea Island Coalition are seeking an extensive study, known as a programmatic environmental impact statement, to weigh the effects of new pit plants on the environment and people who live near them.

Federal officials have sought the new plants to update the nuclear arsenal, a prospect that project boosters say could provide 1,000 jobs at the Savannah River Site, the Aiken area weapons complex where a pit factory would be located.
