Last month, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published a Notice of Proposed Rulemaking (NPRM) with regards to potential harmonization with relevant international Standards. This NPRM (HM-215K) also proposes regulations that do not harmonize with international Standards as well.
One of the more interesting proposals is with regards to limited quantities.
PHMSA is considering the adoption of international standards for limited quantities into the Hazardous Materials Regulations (HMR). With relative low risks in transporting limited quantities and the potential in savings and efficiency for transportation, limited quantity designations may be eliminated within three years or January 1, 2014.
