More than half (54%) of rail tank cars carrying Class III flammable liquids in 2020 met new safety requirements, an increase from the 48% in 2019, according to a U.S. Bureau of Transportation Statistics (BTS) report released yesterday.
The 2015 Fixing America’s Surface Transportation (FAST) Act requires that, by 2029, all Class 3 flammable liquids are carried in DOT-117 or DOT-117R rail tank cars, which meet new safety standards.
The Fleet Composition of Rail Tank Cars Carrying Flammable Liquids: 2021 Report measures progress toward this transition. Class 3 flammable liquids most commonly include crude oil, ethanol and refined petroleum products.
A new deadline for 2020 was the phase-out of nonjacketed CPC-1232 tank cars carrying crude oil. While the report includes some trips by these cars carrying crude oil, all such trips occurred before the April 1, 2020, deadline. The remaining jacketed CPC-1232 tank cars carrying crude oil are due to be replaced, retrofitted, or repurposed by May 1, 2025.
Jacketed DOT-111s were required to stop carrying crude oil in 2018. Nonjacketed DOT-111s have not carried crude oil since 2016.
In 2020, 111,177 rail tank cars were used to carry Class 3 flammable liquids, an increase of 15% from the 94,335 tank cars used in 2016. In 2016, only 8% of the fleet carrying crude oil and other Class 3 flammable liquids consisted of DOT-117s (new or retrofitted), compared to 54% in 2020. For crude oil alone, 81% of the tank car fleet in 2020 consisted of DOT-117s, up from 72% in 2019.
Survey results indicate that 7,413 DOT-117 and DOT-117R tank cars are projected to be built or retrofitted in 2021.
