Revising Requirements and Exceptions for Storing Explosives

The Bureau of Alcohol, Tobacco, Firearms, and Explosives ("ATF") proposes amending Department of Justice regulations listing exceptions to the requirement that explosive materials must be stored in locked magazines. Specifically, ATF proposes adding a testing exception; removing restrictions limiting existing exceptions to materials being physically handled or transported to a site for storing or using; excepting materials to be imminently used or transported; and adopting a perforating gun exception. These changes would streamline on-site operations, acknowledge developments in industry practices, increase safety during these activities by reducing how often explosives are moved, and eliminate the requirement for type 3 magazines.
