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.

Site-wide Environmental Impact Statement
Site-wide environmental impact statements (SWEIS) analyze the potential environmental impacts associated with reasonable alternatives for continuing operations of a facility or site and foreseeable new and/or modified operations and facilities for a period of approximately 15 years.

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.

Hazardous Waste Source Reduction and Management Review Act
Passed in 1989, Senate Bill 14 (SB14), the Hazardous Waste Source Reduction and Management Review Act, requires hazardous waste generators to consider source reduction as the preferred method of managing hazardous waste as it avoids waste generation and management liability. Documents below identify processes at LLNL that generate major portions of the waste within an identified major waste stream and evaluate source reduction opportunities for the waste generating process.
