1 Regional Modeling Center Progress Report October 11, 2007 Gail Tonnesen, University of California, Riverside Ralph Morris, ENVIRON Corporation Int., Novato, CA Zac Adelman, University of North Carolina

2 2007 Task Updates CMAQ visibility modeling. BART Modeling. Data transfer and Data archiving. Budget Update. Plans for 2008.

3 CMAQ Modeling Completed CMAQ 2018 Preliminary Reasonable Progress Case, results available at: CMAQ 2002 Planning Case Version D is in progress.

4 BART Modeling BART modeling was completed spring Have had to redo several simulations because of: Changes in emissions from states. Undocumented limitations in CALPUFF model inputs. Limited CALPUFF results to within 300 km of source in most cased Exception South Dakota where CAMx was also used Results similar to CALPUFF so fill back to CALPUFF Subject-to-BART screening modeling completed Some sources wanted to update modeling with corrections Not necessarily WRAP s issue

9 Example Utah CALPUFF BART Results Huntington Unit#2 Pre-Control UT SRC04 current Huntington Unit #2: SO2 = 24,252 TPY; NOx = 8375 TPY Annual Average Natural Conditions Class I Areas with at least 1 receptor within 300 km of source Minimum Distance 98th percentile for each year 98th (km) year AVG Capitol Reef National Park Canyonlands National Park Arches National Park Bryce Canyon National Park Zion National Park Grand Canyon National Park Black Canyon of the Gunnison Wilderness Area Mesa Verde National Park

10 Example Utah CALPUFF BART Results Huntington Unit#2 Post-Control UT SRC08 Controlled Huntington Unit #2: SO2 = 800 TPY; NOx = 1,733 TPY Annual Average Natural Conditions Class I Areas with at least 1 receptor within 300 km of source Minimum Distance 98th percentile for each year 98th (km) year AVG Capitol Reef National Park Canyonlands National Park Arches National Park Bryce Canyon National Park Zion National Park Grand Canyon National Park Black Canyon of the Gunnison Wilderness Area Mesa Verde National Park

11 Data Transfer/Archiving Data transfer: continuing to respond to requests. Not many requests in the last few months. Data archiving in progress. All critical data sets are being archived to hard disks. Copies of data will be available at 2 locations. Disks can be used to distribute data to states and tribes. The data archive plan is posted on the RMC webpage:

12 Budget Status Total 2007 Budget was $119k. Initial funding and amount remaining are: UCR: $52k, $10k remaining. ENVIRON: $41k, $11k remaining UNC: $26k, $8k remaining. Remaining funds budgeted for data transfer, completing current CMAQ simulation, TSS support and project management.

13 2008 Work Plan Possibility for future work include: Performing MM5 and visibility modeling for other years. Providing support for ozone and PM 2.5 modeling. Evaluating changes and updates in emissions data, e.g., changes in ammonia and in biogenic NOx and VOC. Evaluating updates in model science algorithms, including new CMAQ release in 2008 with SOA updates.
