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.

Notifying Permit Applicants of a Regulatory Requirement to Use BACT for Emergency Backup Engines greater than or equal to 1000 BHP
The Air District is notifying permit applicants of achieved-in-practice BACT for large emergency backup engines. This would potentially affect engine permit applications under Air District review by requiring engines meet EPA Tier 4 emissions standards. To view the 3/29/2021 webinar, slides, and FAQs, visit the Workshops and Events web page.

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 and TBACT 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 New Source Review Rule and TBACT New Source Review of Toxic Air Contaminants Rule.
