Cal EPA Headquarters, 1001 "I" Street, Sacramento, CA
On June 20, 2002, the Air Resource Board (ARB) adopted new annual particulate matter (PM) standards after a lengthy public and peer-review process. Both environmental groups and organizations representing industry were keenly interested in publicly participating. Also, during the course of the review, technical issues arose causing ARB staff to modify its initial recommendations. This seminar will present an overview of the PM standard review, along with staff's recommendations for the newly adopted annual standards, the bases for the recommendations, and related issues. A summary of ARB's future PM standard setting activities will also be presented, including short-term standards for PM and our collaborative activities with the federal review process. This seminar is intended to serve as a forum for discussion on the intent of standard setting, as well as the outcome of the Board meeting and lessons learned.
Dave Mazzera received his B.S. in Environmental Toxicology from the University of California, Davis, and Ph.D. in Environmental Science, Health, and Toxicology from the University of Nevada, Reno. As a research assistant with the Desert Research Institute in Reno, he published work on measurement of particulate matter (PM) and analytical and source apportionment techniques, including a unique method for determination of biogenic sulfate contribution to measured PM10 sulfate mass. He has also worked as an environmental consultant in private industry, consulting in the areas of toxicology, environmental science, and risk assessment and risk management. In May of 2001, he joined the staff of the Health and Exposure Assessment Branch of the Research Division at ARB. One of his major commitments has been working with the ARB and Office of Environmental Health Hazard and Assessment staff on the review or the Ambient Air Quality Standards (AAQS) for particulate matter and sulfates, as well as providing support on other standard reviews.
