6/14/2013 Agency Positions on Wood Smoke  California Air Resources Board  Wood smoke a serious threat to public health  Aggravates lung and heart disease  Can cause 10% increase in children's hospital admissions for respiratory symptoms  U.S. Environmental Protection Agency  Wood smoke can affect everyone  Children, persons with existing health conditions most vulnerable  Health risks can be reduced by switching to gaseous fuels PM Health Guidance  National Ambient Air Quality Standards for PM2.5:  Annual Average: 12 m g/m 3  24 Hour Average: 35 m g/m 3  Guidance for Public Health Officials for Wildfire Smoke  Recommended protective measures based upon shorter term PM exposure  Includes Time frames as short as 1 to 3 hours for both PM2.5 and PM10:  89 - 138 m g/m 3 - Unhealthy for Sensitive Groups (USG)  139 - 351 m g/m 3 - Unhealthy – “consider canceling public events, based on public health and travel considerations”  352 - 526 m g/m 3 - Very Unhealthy Lipsett, Michael and Barbara Materna, Wildfire Smoke A Guide for Public Health Officials , 2008. 3

6/14/2013 Beach Fire Pit Emissions  Assessed the emissions of a single fire ring for one evening  One fire event assumed to burn 2 bundles of wood (approx. 32 lbs total)  Assumed CARB fireplace emission factor  Compared emissions to that of an average on- road 2013 Heavy Duty Diesel Vehicle (HDDV)  One fire pit in one evening estimated to emit as much PM2.5 as one Heavy-Duty Diesel Truck driving 564 miles SCAQMD Monitoring Studies  Purpose  Assess potential for human exposure to wood smoke from beach fires  Approach  Deploy a combination of monitoring technologies and sampling strategies  Other Considerations  Shifting meteorology, variable activity levels, technology limitations 4
