BACT / TBACT Workbook

View the BACT/TBACT Workbook, a resource for guiding permit applicants and Air District staff through one step of the New Source Review permitting process.

The Air District’s Best Available Control Technology and Best Available Control Technology for Toxics Workbook (PDF) is designed to provide guidance on the BACT(83 Kb PDF, 2 pgs, revised 06/09/15) and TBACT(83 Kb PDF, 2 pgs, revised 06/09/15) requirements for commonly permitted sources subject to New Source Review in the Bay Area. Each source subject to these requirements in analyzed on a “case by case” basis to determine compliance with these requirements and not all cases are covered by the guidance.

This workbook serves as a guide for permit applicants, Air District engineers, and others interested in understanding emissions limits, control devices, and techniques needed to meet the BACT(83 Kb PDF, 2 pgs, revised 06/09/15) New Source Review Rule and TBACT(83 Kb PDF, 2 pgs, revised 06/09/15) New Source Review of Toxic Air Contaminants Rule.
