CFATS Advisory Opinion 2016-002: “A Commercial Grade” Interpretation

This is the Chemical Facility Anti-Terrorism Standards (CFATS) Advisory Opinion 2016-002: “A Commercial Grade” Interpretation.

Summary: Any facility that holds a chemical of interest (COI) listed in Appendix A at or above the specified screening threshold quantity (STQ) and concentration must report these COI to the Agency via a Top-Screen survey. A number of COI listed on Appendix A do not have associated specific, numerical minimum concentrations. In lieu of numerical concentrations, the COI are listed with the qualifier “ACG,” which stands for "A Commercial Grade." The Cybersecurity and Infrastructure Security Agency (CISA) has received multiple inquiries from the stakeholder community requesting clarification of the term “A Commercial Grade.” This advisory opinion contains the Agency's interpretation of the term “A Commercial Grade” as used in CFATS.
