Any facility that comes into possession of an Appendix A Chemical of Interest (COI) at or above the applicable Screening Threshold Quantity (STQ) has 60 days to complete and submit a Chemical Security Assessment Tool (CSAT) Top-Screen to the Department.
Following the Department’s review of a facility’s CSAT Top-Screen submission, the facility may be notified in writing that it is required to complete and submit a CSAT Security Vulnerability Assessment (SVA). A facility that receives such a letter is initially considered high-risk and preliminarily assigned to Tier 1, 2, 3, or 4. Unless specifically notified by the Department, the SVA must be submitted within 90 days from the date of written notification. Preliminary Tier 4 facilities may elect to submit an Alternative Security Program (ASP) in lieu of an SVA.
