Chemical Facility Anti-Terrorism Standards (CFATS)

CFATS introduced a new category of sensitive but unclassified information that protects security-related information developed pursuant to CFATS. This category of information, known as Chemical-Terrorism Vulnerability Information (CVI), borrows aspects from existing information protection regimes such as Sensitive Security Information (SSI) and Protected Critical Infrastructure Information (PCII). All covered facilities subject to CFATS must comply with CVI requirements.

On September 22, 2008, DHS published Safeguarding Information Designated as Chemical-Terrorism Vulnerability Information (CVI), Revised CVI Procedural Manual.
