Overview of WRAP Regional Haze Modeling

1. Overview of WRAP Regional Haze Modeling WRAP Regional Modeling Center (RMC) University of California at Riverside ENVIRON International Corporation Presented at: July 10, 2002 WRAP Section 309 SIP Coordination Meeting, Denver, CO

2. RMC goals and staff Models and Model Scenarios Training and Technology Transfer Outline

3. WRAP RMC Goals • Provide annual modeling of regional haze to support development of Section 309 and 308 SIPs and TIPs. • Improve accuracy of key model inputs. • Capacity Building - Provide applied training in use of models. • Technology transfer of models and datasets to States/Tribes. • Project Timeline: January 2001 to December 2002

4. RMC Modeling Goals • Section 309 SIPs/TIPs. • Compare REMSAD and Models-3/CMAQ. • Select a model for annual simulations. • Complete model runs for 1996 Base Case, 2018 Base Case and 6 emissions control scenarios. • Due date: 309 models originally targeted for 1/02 • Provide Training and Transfer datasets and models to States/Tribes.

5. RMC Modeling Goals • Section 308 SIPs/TIPs • Improved Emissions Inventories. • Evaluate Meteorology and Met processing. • Test New Aerosol Formation Mechanisms. • Updated Gas Phase Chemistry (RACM or SAPRC). • Finer Resolution Nested Domains.

10. REMSAD and CMAQ Comparison completed in January, 2002. CMAQ was selected for subsequent modeling of emissions reduction strategies. Model Evaluation and Model Selection for Section 309

11. Year 1996 Scenarios Base Case with actual 1996 wildfires (completed 1/02) Base Case with typical year fire (completed 6/02). Year 2018 Scenarios (with typical year fire) Base Case BART BART w/ Uncertainty Milestone (Annex) No On-road Mobile Emissions No Road Dusts CMAQ Simulations

12. Introduction to modeling class in collaboration with ITEP. Four training seminars in SMOKE and CMAQ at UCR: 1 week training includes CMAQ and SMOKE. 54 participants Training Seminars
