1670-AA00 201904 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 entitled "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." DHS intends to publish a notice announcing the availability of a redacted version of a technical report developed by Sandia National Laboratories titled Ammonium Nitrate Security Program Technical Assessment. The report documents Sandia National Laboratories’ technical research, testing, and findings related to the feasibility of weaponizing commercially available products containing ammonium nitrate. DHS intends to use this notice to solicit comments on the report and its application to the proposed Ammonium Nitrate Security Program rulemaking.
