Washington-The U.S. Department of Homeland Security’s (DHS) Infrastructure Security Compliance Division was scheduled to issue Final Tier 3 determination notifications, as part of the Chemical Facility Anti-Terrorism Standards (CFATS) implemented in 2007, to approximately 400 high-risk chemical facilities on July 31, according to the Agricultural Retailers Association (ARA). Site Security Plans for these facilities will be due to DHS on Nov. 30, 2009. ARA said DHS has indicated that these 400 facilities do not represent the anticipated full universe of final Tier 3 facilities, but rather only those for which DHS has already made final determinations. Over the next several months, said ARA, DHS will continue to issue final tiering determination notifications to facilities across all four tiers.
