Recommendations for Tank Cars Used for the Transportation of Petroleum Crude Oil by Rail

Notice of Safety Advisory.

This safety advisory provides notice to all persons who offer for transportation, or transport, in tank cars by rail in commerce to, from or within the United States, a bulk quantity of UN 1267, petroleum crude oil, Class 3, that originates in or is sourced from the Bakken formation in the Williston Basin (Bakken crude oil). The purpose of this advisory is to encourage offerors and rail carriers to take additional precautionary measures to enhance the safe shipment of bulk quantities of Bakken crude oil by rail throughout the United States. Specifically, in light of recent accidents involving the shipment of Bakken crude oil by rail, the Federal Railroad Administration (FRA) and the Pipeline and Hazardous Materials Administration (PHMSA) urge offerors and carriers of Bakken crude oil by rail tank car to select and use the railroad tank car designs with the highest level of integrity reasonably available within their fleet for shipment of these hazardous materials by rail in interstate commerce. Further, FRA and PHMSA advise offerors and carriers of Bakken crude oil to avoid the use of older, legacy DOT Specification 111 or CTC 111 tank cars for the shipment of such oil to the extent reasonably practicable.
