The District has published a new "Revised BACT Guidance Document" in November 2023 to serve as a guideline to assist in BACT determinations for permitting of new, modified, replaced, or relocated equipment and processes. The Revised BACT Guidance has updated information related to the use of the federal, state and local districts’ BACT Clearinghouses and Guidelines to determine BACT requirements. The Revised BACT Guidance document can be accessed here on our new BACT Webpage.
