SUMMARY: PHMSA is concerned that current requirements may not adequately address the risks associated with the storage of explosives while they are in transportation. On November
16, 2005, we published an advance notice of proposed rulemaking to solicit comments concerning measures to reduce those risks. The comment period closed February 14, 2006. To ensure that
our stakeholders are fully aware of the risks we are addressing and given sufficient opportunity to comment, this ANPRM re-opens the comment period (to close again on October 1 2008), summarizes the comments already in the docket, and announces a Public meeting (August 7, 2008, starting at 9 a.m. and ending at 1 p.m.).
