The PM Standards - Where Are They Now?

Dave Mazzera, Ph.D., Air Resources Board

February 20, 2003
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.
