This final rule removes undue regulatory burdens by adopting the provisions of U.S. Department of Transportation (DOT) special permit (SP) 14175 to authorize a 10-year requalification period and the ultrasonic examination (UE) testing method for DOT specification 3A and 3AA cylinders in flammable and non-flammable, nonpoisonous gas service. This adoption reflects advances in testing technology and will relieve stakeholders of the burden of performing more frequent cylinder requalification.

This final rule modernizes the Materials of Trade (MOT) exception in the Hazardous Materials Regulations (HMR) by increasing the maximum allowable quantities of lithium batteries that can be transported as MOTs. This increase removes an undue regulatory burden which constrains the ability of construction, landscaping, mowing, tree service, food service, and entertainment companies to perform their trade.

This final rule reduces undue regulatory burdens by eliminating or replacing various rail transportation requirements that are either obsolete, overly burdensome, or conflict with other requirements in the Hazardous Materials Regulations.

Instead of maintaining a duplicative list, the regulations will now rely on the authoritative, comprehensive list already maintained by the U.S. Environmental Protection Agency.

This final rule removes undue regulatory burdens by allowing regulated entities to use a reduced sized marking for limited quantity shipments of hazardous materials by highway, rail, or vessel.

This final rule removes undue regulatory burdens by adopting the provisions of U.S. Department of Transportation (DOT) special permit (SP) 21478 to allow empty intermediate bulk containers (IBCs) that only contain the residue of a hazardous material to be transported without shipping papers, placards, and United Nations (UN) identification (ID) numbers.

This final rule removes undue regulatory burdens by adopting the provisions of U.S Department of Transportation (DOT) special permit (SP) 21287 to streamline the transportation of refrigerating machines-- including common household appliances like refrigerators, window- mounted air-conditioning units, and dehumidifiers--that contain small quantities of certain low flammability refrigerant gases.

This final rule removes undue regulatory burdens by adopting the provisions of U.S. Department of Transportation (DOT) special permit (SP) 21379 to streamline the transportation of refrigerating machines and components containing certain low flammability refrigerant gases.

This final rule amends the Hazardous Materials Program Procedures to allow an application to renew a special permit or approval to be filed any time on or before its expiration date rather than requiring the renewal application to be filed 60 days in advance as under the current regulations.

PHMSA is amending the Hazardous Materials Regulations by updating the definition of an aerosol to eliminate unnecessary regulatory burdens and maintain consistency with current international transportation standards.

This final rule removes undue regulatory burdens by allowing for the continued use of packagings authorized under a manufacturing special permit for the useful life of the package. Manufacturing special permits typically authorize the manufacture, mark, sale, and use of the packaging authorized by the special permit.

Breakout tanks are used to "relieve surges in a hazardous liquid pipeline system" or to "receive and store hazardous liquid transported by a pipeline for reinjection and continued transportation by pipeline." American Petroleum Institute Standard 653 (API Std 653) sets industry standards for the inspection, repair, alteration, and reconstruction of aboveground storage tanks. PHMSA currently incorporates the 3rd edition of API Std 653 (issued December 2001) by reference into its regulations for breakout tanks. In this rulemaking, PHMSA is proposing to update its regulations for breakout tanks to incorporate the 5th edition of API Std 653 (issued November 2014) by reference. As a key part of this, PHMSA is proposing to authorize the use of risk-based inspection (RBI) procedures for establishing the inspection intervals of in-service breakout tanks.

PHMSA is making a technical correction to a January 14, 2026 final rule that amended the class location change requirements. The final rule allows an operator to confirm or to restore the maximum allowable operating pressure (MAOP) of an eligible gas transmission pipeline segment that experiences a class location change by implementing an integrity management (IM) alternative. For MAOP restorations, PHMSA is clarifying in this correction notice that the 24-month deadline for implementing the initial programmatic requirements of the IM alternative runs from the effective date of the final rule or the date that an operator decides to initiate an MAOP restoration, whichever is later. This clarification is consistent with the requirements in the final rule, including the deadline in the IM alternative that applies to MAOP confirmations, which runs from the effective date of the final rule or the date of the class location change, whichever is later.
