1. TAF Meeting, Las Vegas, NC, 2/6/2007 Regional Modeling Center Proposed 2007 Work plan February 6, 2007 Gail Tonnesen, University of California, Riverside Ralph Morris, ENVIRON Corporation Int., Novato, CA Zac Adelman, University of North Carolina TAF Meeting, Las Vegas, NV

2. TAF Meeting, Las Vegas, NC, 2/6/2007 2006 Task Status Completed the 2002 Planning Case and 2018 Base Case CMAQ simulations and visibility projections. Final model scenarios: –Plan 2002 C (included corrections to eastern US point sources). –Base 2018 B Source Apportionment Modeling completed using CAMx/PSAT BART CALPUFF modeling nearing completion. Fire emissions sensitivity studies completed. Tech Support and Data Transfer ongoing.

3. TAF Meeting, Las Vegas, NC, 2/6/2007 2006 Tasks Deferred Several emissions and visibility modeling tasks from 2006 were deferred, funds carried over: –emissions processing: $28,500 remaining –visibility modeling: $43,000 remaining –Alaska BART Modeling: $5,000 remaing Cost overruns on several tasks including: –BART CALPUFF Modeling –Fire emissions sensitivity studies –Tech Support and Data Transfer –Project adminsitration, conference calls, travel Net carry over from 2006 as of Jan 1, 2007 is $66,742.

4. TAF Meeting, Las Vegas, NC, 2/6/2007 Proposed 2007 Work Plan Visibility modeling using CMAQ –2018 Preliminary Reasonable Progress (PRP): $18,000 –Two emissions sensitivity simulations: $12,400 each Additional PSAT simulations needed? –Reccomended only if there are large changes in emissions. Data transfer: $11,000 Data archiving: $13,141 Computer & website maintence and hard disks: $9,100 Project administration, conference calls, travel: $49,000 Total proposed budget for 2007: $119,000
