The Department of Homeland Security (DHS) published its Chemical Facility Anti-Terrorism Standards (CFATS) October 2018 Quarterly Update, with a focus on Material Modifications and new Top-Screens. In the Quarterly, DHS highlighted the following:
- Facilities have 60 days from the time they come into possession of a Chemical of Interest (COI) at or above the Screening Threshold Quantity (STQ) and concentration to report the COI to DHS via a Top-Screen.
- Facilities must report Material Modifications to chemical holdings and facility operations, which may include: the addition or removal of COI at the STQ and concentration; or changes to quantity, location, or packaging of a COI as previously reported on a Top-Screen.
- Facilities are encouraged to report the highest expected quantity and concentration of a COI they anticipate possessing over the lifecycle of their operations.
- Tier 1 and Tier 2 facilities must update their Top-Screens two years after CFATS security plan approval.
- Tier 3 and Tier 4 facilities must update their Top-Screens three years after CFATS security plan approval.
