Health Impacts Analysis:

Actions to Update the Methodology for Estimating
Premature Death Associated with Fine Airborne
Particulate (PM2.5) Exposure

As part of the Air Resources Board's development of the Emission Reduction Plan for Ports and Goods Movement, ARB staff performed a health impacts analysis for domestic and international goods movement activities. At the April 20, 2006 Board meeting, staff presented the results of this analysis, which can be found in Appendix A at http://www.arb.ca.gov/planning/gmerp/gmerp.htm. Following the presentation, staff was directed by the Board to update the health impacts methodology to reflect recent health information on PM2.5 exposures and premature death. On August 21, 2006 we held a public workshop to discuss our approach for revising the methodology and our timeline for completing the work. Staff reviewed all relevant literature and completed a draft report incorporating public comment received at the workshop. A formal review of the updated methodology and analysis was conducted by a peer review committee formed by the University of California. The committee is composed of experts in the fields of epidemiology, air quality measurement, risk management, health effects of air pollution, and biostatistics.

The draft staff report was discussed at the May 22, 2008 Air Resources Board meeting and made available for public comment. Also, a workshop to discuss the draft methodology was held on June 25, 2008. Public comments received by July 11, 2008 will be considered in drafting the final report, which we anticipate will be released to the public later in 2008.

This fact sheet provides background on particulate matter and the health risks it poses.
