On July 11, 2014 PHMSA issued a final rule amending the Hazardous Material Regulations on radioactive materials. The purpose of this ruling is to clarify the HMR concerning the transportation of such materials. In addition to their own changes PHMSA also incorporated changes that were adopted from the 2009 publication of the IAEA Safety Standards.
PHMSA worked closely with the NRC during the development of this rule. Although they do expect the NRC to publish a parallel final rule there is no date currently set for that so there is a risk of differences in overlapping proposals that may affect the compatibility of both the PHMSA and NRC regulations.
