Public comments will be addressed in the Record of Decision to be published later this year. Lawrence Livermore National Laboratory's (LLNL's) Environ- mental Report 1993 was released in December 1994 by the Department of Energy(DOE). The report summarizes the Site 300 Fact Sheet Number Two results of the Lab's environmental monitoring program and concludes that Lab operations do not threaten human health Distributed or the environment. The report also finds that the Laboratory is in compliance with local,state, and federal environmental The Site 300 Fact Sheet Number Two is now available. It regulatory requirements. summarizes the Site-Wide Remedial Investigation (SWRI) report issued by DOE/LLNL in April 1994 and describes the In preparation for writing this report, LLNL's Environmental findings from 10 years of investigations at Site 300. The Fact Protection Department (EPD) studied the results of more than Sheet also discusses the human health risk assessment, com- 190,000 analyses of environmental samples taken on and off pleted as part of the SWRI, which analyzes the potential the Lab site.

The samples were then examined to to regulatory agencies; defines study areas, operable units, and see if any trace of radioactivity and nonradioactive pollutants unassigned sites; and describes the progress of clean-up activi- could be detected. ties and upcoming environmental restoration activities. A copy of the SWRI is available at the Tracy Library and the The analysis shows that the amount of radiation released from LLNL Reading Room. the Lab continues to be far below the regulatory limits set to protect the public. In 1993,radiation from the Lab was less than 1%of the Environmental Protection Agency(EPA) standard. E Calls Labs Internal The amount of radiation released was slightly higher in 1993 IU than in 1992 due to extensive radionuclide inventory reduction Environmental Communications and clean-up activities in the Lab's tritium facility. However, Exemplary the highest dose that an individual member of the public could p y receive was calculated to be slightly lower due to mild wind patterns in 1993. The Environmental Management Assessment,conducted last summer by DOE's Office of Environmental Audit,found LLNL's internal environmental communications exemplary. The report Public Meeting onuil in 834 stated that all levels of Lab management and staff exhibited a g high level of commitment to environmental excellence. Remediation Plan Several areas were singled out as"exceptional"by the DOE, The area designated Building 834 is the first of six areas at the including the Laboratory's emergency preparedness planning Lab's Site 300 for which a plan was developed for remediating and response program, the Lab's internal communications traces of trichloroethylene (TCE)found in soil,rock, and program(for effectively conveying awareness of environmental ground water. The plan was discussed at a public meeting in issues), and the Lab's environmental planning program. Tracy,California,on Tuesday,January 24, 1995.

Most of these had previously questions and concerns from the public. been identified by the Lab and DOE's Oakland Operations Office, and corrective actions have been planned or completed.
