Status of Emissions Inventories

1
Status of Emissions Inventories

• Resolving final issues with ammonia inventory
• Developing baseline inventories for interim year
  for neighboring air basin analyses (2009, 2013)
• Mobile source issues speed correction
  adjustments for future years (CARB SCAG)
• Developing day specific episodic PM2.5
  inventory
• Reviewing PM inventories - Paved
  road dust (silt loading)
• - Neighborhood scale (Rubidoux)

Status of Air Quality Modeling

• CAMx 4.4 with updated SAPRC99 chemistry -
  Benchmark comparisons (4.4 vs. 4.2) -
  Comparisons with alternate emissions allocation
• Running base years, 2002 and 2010 to develop
  preliminary RRFs
• Comparisons with CALMET vs MM5/FDDA
• PM2.5 2005 and 2015 base - Assessing
  selected boundary conditions - Testing across
  the board emissions reductions - Comparing to
  speciated rollback
• Meeting with CARB to finalize modeling approach
• Finalize Modeling Protocol
