Changes to 2002 Base Year Inventory (Base 4)

• Incorporated Midwest RPO Base K inventory for
  MRPO states -- all sectors except onroad mobile
• Adjusted Missouri area source inventory
• Added portable fuel container (gas cans)
  emissions statewide
• Corrected aircraft refueling emissions at Lambert

2009 On-the-Books Inventory Electric Generating
Units (EGUs)

• Integrated Planning Model (IPM) emissions
  projections that implement state/local
  regulations, NOx SIP Call, CAIR trading program,
  and stakeholder unit-level revisions
