DOT Seeks to Harmonize HazMat Regs

January 9, 2019

The Department of Transportation’s (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) has issued a Notice of Proposed Rulemaking (NPRM) (HM-215O – Harmonization with International Standards) to amend its Hazardous Material Regulations (HMR) to maintain alignment with international regulations and standards that became effective on January 1, 2019.

Proposed actions by PHMSA in the NPRM include a classification scheme and transport provisions for articles containing hazardous materials that do not already have a proper shipping name, non-testing methods to classify corrosive materials, recognition of one-time movement approvals issued by Transport Canada, and the incorporation by reference of international standards, such as the International Maritime Dangerous Goods (IMDG) Code, the International Civil Aviation Organization Technical Instructions (ICAO TI), the latest editions of the UN Model Regulations, and the International Organization for Standardization (ISO) technical standards applicable to cylinders.

PHMSA said its proposed harmonization will enhance safety, facilitate compliance, and improve the efficiency of the global transportation system. 

However, there are some amendments to the international standards that PHMSA is not currently proposing, including fuel gas containment systems, severely damaged and defective lithium batteries, and road gas elements vehicles.

ILMA currently is analyzing PHMSA’s NPRM.
