An environmental group has sued the U.S. Department of Energy (DOE) seeking to block construction of a planned $4 billion nuclear research facility in Los Alamos, New Mexico. The Los Alamos Study Group v. DOE, No. N/A (D.N.M. filed 8/16/10). The complaint alleges that DOE’s National Nuclear Security Administration violated NEPA by expanding the size of the proposed Chemistry and Metallurgy Research Replacement Nuclear Facility without updating the project’s environmental impact statement (EIS).  

The plaintiff argues that since the original EIS was submitted in 2003, the facility’s projected cost has risen roughly by a factor of 10 from its original estimate of between $350-500 million and the construction time has increased from three years to more than a decade. The complaint seeks a declaratory judgment and an injunction requiring DOE to prepare a new EIS that addresses the project in its current form and an order prohibiting any investment in the project until the EIS is submitted.
