  2. Statewide Application Emissions and Meteorology ChallengeInventory Microscale Modeling Regional Modeling • Traditional areawide sources become point sources for microscale modeling • Increase in spatial resolution needs are not always supported by inventory data Integrated Results Risk Assessment Mapping and Visualization

  3. Statewide Application Emissions and Meteorology ChallengeMeteorology Microscale Modeling Regional Modeling • Observations not available everywhere in the state for microscale plume models Integrated Results Risk Assessment Mapping and Visualization

  4. Statewide Application Emissions and Meteorology ChallengeMicroscale Model Microscale Modeling Regional Modeling • Statewide application easier to implement by selecting only one microscale model Integrated Results Risk Assessment Mapping and Visualization

  5. Statewide Application Emissions and Meteorology ChallengeMicroscale for Roadways Microscale Modeling Regional Modeling • Microscale modeling on annual average basis is not well established Integrated Results Risk Assessment Mapping and Visualization

  6. Statewide Application Emissions and Meteorology ChallengeRegional Modeling Resolution Microscale Modeling Regional Modeling • Increase resolution for community assessments Integrated Results Risk Assessment Mapping and Visualization

  7. Statewide Application Emissions and Meteorology ChallengeIntegration of Results Microscale Modeling Regional Modeling • Double counting of microscale and regional modeling results Integrated Results Risk Assessment Mapping and Visualization

  8. Statewide Application Emissions and Meteorology ChallengeRisk Assessment and Mapping Microscale Modeling Regional Modeling • Cancer and Chronic inhalation risk estimates may be feasible • Exploring ways to convey both averages and peaks Integrated Results Risk Assessment Mapping and Visualization

  9. Next Steps

  10. Next Steps • Microscale • Prepare Report for Barrio Logan • Barrio Logan model performance - tracer studies • Wilmington Protocol & Analysis • Regional - Statewide • Prepare toxic inventory • Prepare meteorological files • Run air quality model • Statewide Protocol Development • Currently under development • Draft Protocol will be available in June to Peer Review Group • Continue Developing Statewide Tools

  11. Schedule • December 2003 • Recommend plan for cumulative risk assessments at neighborhood scale for Statewide application • Replace risk maps (ASPEN) for Southern California • Continue meetings (July 8, 2003) with working group • Second peer review group
