Chemical-terrorism Vulnerability Information

Chemical-terrorism Vulnerability Information (CVI) is the information protection regime authorized by Section 550 of Public Law 109-295 to protect from inappropriate public disclosure any information developed or submitted pursuant to Section 550. This includes information that is developed and/or submitted to DHS pursuant to the Chemical Facility Anti-Terrorism Standards (CFATS) regulation which implements Section 550.

Chemical facilities expect that the information provided to DHS will be protected from public disclosure or misuse. DHS expects individuals in possession of CVI to safeguard it with equal care. Following the requirements in 6 CFR § 27.400 and the guidance in the CVI Procedures Manual will ensure sensitive information about the Nation's high-risk chemical facilities is safeguarded.
