Shippers of highly toxic materials, such as chlorine, and shippers of other hazardous materials both domestically and internationally may benefit from a recent final rule issued by the Pipeline and Hazardous Materials Safety Administration (PHMSA) on November 7, 2018. 83 Fed. Reg. 55792 (Nov. 7, 2018). The rule eases or eliminates certain PHMSA requirements for hazardous materials transportation, including by:

  • Extending the service life of interim compliant toxic inhalation hazard tank cars to the full service life of all other tank cars. This enables the use of interim cars beyond 20 years.
  • Generally allowing the use of labels and placards that meet international standards. This may reduce the labeling and placarding burden on those who ship hazardous materials domestically and internationally.
  • Incorporating by reference certain Chlorine Institute publications. This may eliminate the need for some special permits related to chlorine transportation.
