DHS reinstated the requirement that facilities that manufacture, use, store, or distribute certain amounts of designated high-risk chemicals submit reports (called “top screens”) to DHS within 60 days and is also requiring facilities that previously submitted top screens to submit new ones using the recently released Chemical Facility Anti-Terrorism Standard (CFATS) Top Screen tool. Earlier this year, DHS had suspended the regulatory requirement imposed on covered facilities to submit top screens while it developed a new CFATS tiering methodology for assessing risk.
