Chemical Facility Anti-Terrorism Standards: Top-Screen Submission Considerations Fact Sheet


The Cybersecurity and Infrastructure Security Agency (CISA) has reviewed tens of thousands of Top-Screens submitted by chemical facilities under the Chemical Facility Anti-Terrorism Standards (CFATS) regulation. Based on these reviews, CISA has identified helpful tips to assist facilities with completing and submitting a Top-Screen.

This fact sheet provides considerations for facilities that are submitting a Top-Screen, including those that are frequently changing the quantities of chemicals of interest (COI), planning for potential operational changes in the future, or ceasing operations.
