The University of California manages the LLNL Livermore Site and Site 300 for the U.S. Department of Energy(DOE). LLNL and DOE have a number of programs underway to ensure that LLNL operations are environmentally sound and protective of both employee and community health. These programs include initiatives to reduce the overall amount and toxicity of wastes produced by Laboratory operations. DOE/LLNL also are addressing problems linked to past handling and storage of hazardous and radioactive materials at the Livermore Site and Site 300,under the federal Superfund program. All environmental programs are overseen by State and federal regulatory agencies. u Cleanup Milestone Marked For Livermore Site LLNL and DOE officials noted the start-up of a new volatile organic compounds—VOCs).
