Disclosure of Chemical-Terrorism Vulnerability Information (CVI)

Access to or disclosure of Chemical-terrorism Vulnerability Information (CVI) requires that an individual (1) has a need to know the information and (2) is a CVI Authorized User. Under the Chemical Facility Anti-Terrorism Standards (CFATS) (6 CFR § 27.400), a covered person is an individual who has a need to know CVI or someone who gains access to what they know to be or reasonably know to constitute CVI.

Access to and/or disclosure of CVI is based on the following general principles:

  1. Except in exigent or emergency circumstances, CVI may only be disclosed to CVI Authorized Users with a need to know.
  2. A need to know should be assessed on a case-by-case basis (typically including an individualized assessment of the documents involved).
  3. A covered person in possession of CVI should take reasonable steps to confirm that any individual seeking access to CVI is a CVI Authorized User and has a need to know.

CISA provides each CVI Authorized User with a unique identification number. Before sharing CVI, ask for this number. You can contact the CSAT Help Desk at 866-323-2957 to confirm a person's CVI Authorized User status.

Safeguarding CVI

All covered persons must comply with the handling and safeguarding requirements for CVI outlined in 6 CFR § 27.400, be familiar with the CVI Procedural Manual and any other guidance the Cybersecurity and Infrastructure Security Agency (CISA) may provide in the future, and be aware that divulging information without proper authority could result in an administrative compliance order, civil penalties, or other enforcement or corrective actions by the Agency (e.g., revocation of CVI Authorized User status). See 6 CFR §§ 27.300(b)(3) and 27.400(j).
