Burn Determinations During Emergency Response Smoke Events
Emergency Response Events in the SJV
Tracy Tire Fire
Westley Tire Fire
Crippin Waste Wood Fire
Wildfires (Manter, McNally)
Burn Declarations During Emergency Response Smoke Events
Public is sensitized to smoke
Health statements
Overwhelming arguments against adding avoidable emissions into the air
Measured impacts spotty
Cannot monitor everywhere
Analyses Needed During Emergency Response Events
Amount of emissions
Area and magnitude of impact
Complaints
PM and ozone precursor emissions
Plume rise
Actions by air agencies during emergency response smoke events
Monitoring (PM, CO, Toxics, metals)
Health statements
Emission curtailments including burns (STA and PDLT)
Decision of when to resume normal operations

Smoke Impacts During the Control of Crippin Fire
Summary and Conclusions
Quantification of impacts during events is difficult
Complaints and monitoring do not always agree
Decision to allow other burning relies on impact analyses using the corroboration of monitoring, modeling, meteorology and social factors
Discussion
