Benefits of an Annual Average PM2.5 Standard in California
Analysts used the BENMAP model developed for U.S. EPA to assist in preparation of air pollution control policies to compare the impact of a the current annual average PM2.5 NAAQS of 15 µg/m3 with a more stringent standard of 12 µg/m3 in California.
The model estimates that achieving the current standard would avert approximately 4,000 premature deaths in California each year, and that approximately 2,000 additional fewer deaths would occur in California each year as a result of attainment of the more stringent standard.
