Lawrence Berkeley National Laboratory Air Quality Human Health Risk Assessment

Lawrence Berkeley National Laboratory (LBNL)

Berkeley, California, USA


The Lawrence Berkeley National Laboratory (LBNL) facility needed an air-quality-driven risk assessment of potential impacts associated with its proposed long-range development plan and alternatives. This analysis, required by the California Environmental Quality Act, was an integral part of the facility’s subsequent Environmental Impact Report.

Our Role

We developed a comprehensive stationary and mobile source air emissions inventory of over 600 point, area, volume, and fugitive sources of both toxic and radiological emissions. We provided 3D dispersion modeling in a complicated source-receptor geometry and complex terrain setting, and analyzed potential health risk to local residences and facility workers. Documentation included cumulative assessment of contributions from surrounding urban areas and the adjacent University of California at Berkeley campus, as well as a standalone site-wide emissions inventory report.
