National Environmental Policy Act
The National Environmental Policy Act (NEPA) requires federal agencies, including the U.S. Department of Energy (DOE) and its national laboratories, to consider the environmental effects of proposed actions in their decision-making processes and inform and engage the public in those processes.

Comprehensive Environmental Response, Compensation and Liability Act
The Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) was established by the federal government in 1980 to provide a process for cleaning up hazardous waste sites that resulted from accidents, spills or other contaminant releases to the environment. Administered by the U.S. Environmental Protection Agency, CERCLA (also known as “Superfund”) is a multi-phase process for cleaning up a contaminated area. Click a heading below to learn about Lawrence Livermore National Laboratory’s past and ongoing efforts to clean up its legacy waste material.
