Point Updates
EGU- 2005 EGU emissions/heat input from EPA'S Acid Rain Program
Non-EGU Stationary Sources - enhancements were focused on improving the following sectors:

  • HAP data received from States and industry to support the MACT program, including the recent Risk and Technology Review rulemaking
  • 2005 State, local, and tribal data submitted to EPA under the CERR
  • HAP data from Toxic Release Inventory (TRI) for missing facilities and pollutants
  • Off-shore platform data from Mineral Management Services (MMS)

    • Nonpoint Updates

  • 2005 Wildfires and prescribed fires added
  • VOC from fireplaces was revised downward based on a change in the emission factor

    • Mobile Updates
