Presentation Transcript

  1. Burn Determinations During Emergency Response Smoke Events

  2. Emergency Response Events in the SJV • Tracy Tire Fire • Westley Tire Fire • Crippin Waste Wood Fire • Wildfires (Manter, McNally)

  3. 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

  4. Analyses Needed During Emergency Response Events • Amount of emissions • Area and magnitude of impact • Complaints • PM and ozone precursor emissions • Plume rise

  5. 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

  6. Westley Tire Fire(9/22/99-10/28/99)

  7. Tracy Tire Fire (8/1998-12/2000)

  8. McNally Fire22 July 2002 19:10 GMT

  9. Crippin Wood Waste Fire (January 11-February 9, 2003)

  10. San Joaquin Valley APCD Air Quality Monitoring, Analyses, and Forecasting During the Crippin Fire • Twice daily particulate matter reports and forecasts • Health Statements (13) • Declaration of agricultural no burn days • Active attendance at press conferences • Responding to media and issuing press releases • Deploying and operating a monitoring trailer at Chandler Airport and siting guidance to ARB

  11. Agencies Involved in Crippin Fire • EPA • OES • ARB • SJVAPCD

  12. Monitoring Results • Fire impacted monitors on 14 days • 1- hour PM2.5 maximum 228ug/m3 • 24- hour PM2.5 maximum 80ug/m3 • 159 AQI=Unhealthy • Normal maximums in Fresno=205 AQI

  13. Crippin Air Quality Measurements

  14. Modeling fire with ISC

  15. Smoke Impacts During the Control of Crippin Fire

  16. 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
