Lawrence Livermore Laboratory is proposing to build a biosafety level 3 (BSL-3) pathogen research facility for the study of hazardous airborne diseases. Construction costs for the three-lab, 1,100-sf building could reach $1.5-million. Completion could be expected as early as 2003. Lawrence Livermore and New Mexico's Los Alamos Laboratory are the first Department of Energy labs to seek permission to study these pathogens.
