Common Information

Best Available Control Technology (BACT)

The following tables contain information regarding the level of emissions control required or the amount of emissions allowed from the facility.

  • Current BACT - Download the workbook to see BACT for this source and all other sources in this industry type. Note, the workbook also contains current MSS BACT.
  • 10-Year-Old BACT - Some authorizations for qualified facilities allow for air pollution control methods that are at least as effective as the BACT that was required or would have been required 120 months, or 10 years, ago.

Boilerplate Conditions

Since BACT requires process vents to be routed to a control device, see the specific control device being used for its associated boilerplate conditions.
