The Cybersecurity and Infrastructure Security Agency (CISA) is proposing a rulemaking to implement the December 2007 amendment to the Homeland Security Act titled "Secure Handling of Ammonium Nitrate." This amendment requires the Department of Homeland Security to "regulate the sale and transfer of ammonium nitrate by an ammonium nitrate facility...to prevent the misappropriation or use of ammonium nitrate in an act of terrorism." CISA previously issued a Notice of Proposed Rulemaking (NPRM) on August 3, 2011. CISA is planning to issue a Supplemental Notice of Proposed Rulemaking (SNPRM).
