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