Summary
This annual report is prepared pursuant to the National Emissions Standards for Hazardous Air Pollutants (NESHAPs) 40 CFR Part 61, Subpart H; Subpart H governs radionuclide emissions to air from Department of Energy (DOE) facilities. NESHAPs limits the emission of radionuclides to the ambient air from DOE facilities to levels resulting in an annual effective dose equivalent (EDE) of 10 mrem (100 {micro}Sv) to any member of the public. The EDEs for the Lawrence Livermore National Laboratory (LLNL) site-wide maximally exposed members of the public from 1998 operations are summarized here. (1) Livermore site: 0.055 mrem (0.55 {micro}Sv) (57% from point-source emissions, 43% from diffuse-source emissions). The point-source emissions include gaseous tritium modeled as tritiated water vapor as directed by EPA Region IX and is used for compliance purposes. LLNL believes a more realistic dose for the Livermore site is 0.049 mrem (0.49 {micro}Sv) (52% from point-source emissions, 48% from diffuse-source emissions). This dose is based on an assessment that represents a more realistic behavior of tritium gas in the environment. (2) Site 300: 0.024 mrem (0.24 {micro}Sv) (78% from point-source emissions, 22% from diffuse-source emissions). The EDEs were generally calculated using the EPA-approved CAP88-PC air-dispersion/dose-assessment model. Site-specific meteorological data, stack flow data, and emissions estimates based on radionuclide inventory data or continuous-monitoring systems data were the specific input to CAP88-PC for each modeled source.
