Daily Rules, Proposed Rules, and Notices of the Federal Government
The Hazardous Materials Regulations (HMR) issued by the Pipeline and Hazardous Materials Safety Administration (PHMSA) govern the rail transportation of hazardous materials. Title 49 Code of Federal Regulations Section 174.50 of the HMR forbids the transportation by rail of a bulk packaging that no longer conforms to HMR or that is leaking, unless otherwise approved by FRA's Associate Administrator for Railroad Safety/Chief Safety Officer. These approvals are generally referred to as OTMAs.
Recently, FRA revised its OTMA procedures to streamline the overall OTMA process and to minimize unnecessary administrative burdens. On January 31, 2012, FRA issued Hazardous Materials Guidance Number HMG-127, which explained these revised procedures and the criteria for issuance of OTMAs. Based on experience with the procedures and comments received from industry, FRA modified and reissued the procedures in Revision 2 of HMG-127, dated October 31, 2012. The revised HMG-127 is available for review on FRA's Web site at:
