"The CSAT SSP [Chemical Security Assessment Too Site Security Plan] tool collects information from covered facilities regarding existing and if a covered facility so chooses- planned and proposed security measures. Facilities are required to list and/or describe existing security measures as part of their CSAT SSP submission. However, this SSP tool will provide facilities the opportunity to propose that certain existing and/or planned security measures indentified in this tool not to be considered by DHS [Department of Homeland Security] in evaluating their SSPs for Approval. Of course, if a facility relevant to satisfaction of one or more CFATS RBPS [Chemical Facility Anti-Terrorism Standards Risk-based Performance Standards], it is possible that the facility's SSP, as submitted, may not satisfy the application RBPS."
