On November 25<\/span>th<\/span>, 2020, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published a<\/span> final rule<\/span><\/a> amending the hazardous materials regulations by incorporating 24 petitions for rulemaking from the regulated community.\u00a0 The petitions were submitted between February 2015 and March 2018. The changes made in this final rule were effective on December 28<\/span>th<\/span>, 2020.<\/span><\/p>\n

Limited Quantity Exception for Hydrogen Peroxide<\/span><\/h2>\n

UN2014, Hydrogen Peroxide, an aqueous solution, was not authorized as a limited quantity in the<\/span> 49 CFR<\/span><\/a> hazardous material regulations<\/span>. UN2014 is authorized to be shipped as a limited quantity under other modal regulations and the<\/span> UN Model Regulations<\/span><\/a>.\u00a0 The lack of harmonization causes inconsistencies in costs and logistics when shipping this material both domestically and internationally.<\/span><\/p>\n

PHMSA agreed with this petition and added the reference \u00a7173.153 to column 8A of the hazardous materials table authorizing UN2014 for transport as a limited quantity.<\/span><\/p>\n

Markings on Portable Tanks<\/span><\/h2>\n

49 CFR<\/span> \u00a7173.302(b)(2)<\/span><\/a> stated that markings on portable tanks with a capacity of less than 3,785 L (1,000 gallons) have a width of at least 4.0 mm (0.16 inch) and a height of at least 25 mm (1 inch).\u00a0 Section 5.3.2.0.2 of the IMDG Code allows a minimum height of 12 mm (0.47 inch).\u00a0 PHMSA agrees that harmonizing the minimum height of the marking with the IMDG code should facilitate flexibility, cost savings, and efficiencies in transportation. <\/span>\u00a0<\/span>\u00a7173.302(b)(2)<\/span><\/a> is updated to reflect the change in the hazardous material regulations.<\/span><\/p>\n

Harmonizing Limited Quantities of Corrosive Materials<\/span><\/h2>\n

Through a petition request it was pointed out that many proper shipping names for corrosive materials that are not currently allowed to be shipped as limited quantities be updated with the authorization.\u00a0 These materials all have limited quantity authorizations in the model regulations.\u00a0 Allowing these materials to be shipped as limited quantities under the 49 CFR will facilitate harmonization and the cost savings and efficiencies that go with it.\u00a0 PHMSA agreed with the petitioner and updated 114 entries for corrosive materials with authorizations to be shipped as limited quantities.\u00a0\u00a0<\/span><\/p>\n
