  2. Legend Current Modeling Protocol Component of Modeling Model Evaluation Component Proposed Product Cumulative Risk AssessmentTool NAP Modeling Approach Statewide Modeling Protocol Input Data Requirements Emissions and Meteorology Wilmington Modeling Protocol • Model Evaluation • Inventory Data Evaluation • Sensitivity Studies • Uncertainty Analysis • Tracer Studies • Toxics Monitoring • Regional Modeling Evaluation • Work Group Evaluation Microscale Modeling RegionalModeling Barrio Logan Modeling Protocol Integrated Results Risk Assessment Model Strengths and Limitations Updated NAP Modeling Protocol Independent Scientific Peer Review Mapping and Visualization

  3. Cumulative Risk Analysis Continuum • First Tier Assessment (ASPEN) • Refined Assessment (Barrio Logan, Wilmington)

  4. Refined Approach • Protocols such as Barrio Logan and Wilmington • Comprehensive and applicable to small modeling domains • Resource intensive

  5. New Statewide Protocol • Address cumulative exposure at neighborhood scale throughout State • More refined than ASPEN • Not as detailed as the pilot studies in Barrio Logan and Wilmington
