1670-AA00 201910 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 1670 Cybersecurity and Infrastructure Security Agency CISA 1600 Department of Homeland Security DHS Ammonium Nitrate Security Program

This rulemaking will implement the December 2007 amendment to the Homeland Security Act titled "Secure Handling of Ammonium Nitrate." The 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." In June 2019, DHS published a notice announcing the availability of a redacted version of a technical report titled Ammonium Nitrate Security Program Technical Assessment. Sandia National Laboratories developed the report. DHS requested public comments on the report and its application to the proposed definition of ammonium nitrate. DHS will review and consider all the comments received and then determine the next appropriate steps for this rulemaking.
