Toxic Air Contaminants (TAC)

In addition to regulating criteria air pollutants, the BAAQMD maintains a list of Toxic Air Contaminants (TAC) that have reporting thresholds and permit requirements. BAAQMD’s Reg 2, Rule 5 establishes the current TAC list and associated requirements.

The TAC list identifies several common compounds in use at UCSF, although the university’s methodology and research-scale quantities often exempts us from requiring a full permit.  

If you have a proposed experiment, process, or project that uses any of the listed chemicals and you anticipate any volatile emissions from that process, please contact UCSF Environmental Programs for a detailed evaluation.
