Rail Transportation of Crude Oil and the FAST Act: An Update


After a multiyear boom, the volume of crude oil carried by
U.S. railroads has fallen to the lowest level since 2012. This
decline may have implications for efforts by the U.S.
Department of Transportation (DOT) to finalize regulations
concerning the safety of rail transportation of crude.

Increased oil drilling in North Dakota's Williston Basin
(also known as the Bakken), made possible by new drilling
methods such as hydraulic fracturing and directional
drilling, led to a sharp rise in the movement of crude oil by
railroads beginning about 2010 (see Figure 1). Large-scale
oil production was new to the region, which lacked pipeline
capacity to handle the volume. As an alternative, oil
producers began shipping more oil to refineries by railroad.
Some of these trains derailed, leading to oil spills, fires, and
explosions. Several incidents required emergency
evacuations of nearby residents, and one resulted in
fatalities. (For further background, see CRS Report
R43390, US. Rail Transportation of Crude Oil:
Background and Issues for Congress.)

DOT issued emergency orders requiring new safety
measures for oil trains in 2014 and 2015. Congress enacted
or modified many of these measures in the Fixing
America's Surface Transportation Act (the FAST Act; P.L.
114-94, Title VII, Subtitle C) in December 2015. These
measures include use of stronger tank cars, more frequent
safety inspections, speed limits for oil trains, and enhanced
emergency response preparations.


A substantial fall in the volume of crude oil carried by
railroads has taken place since summer 2015, as shown in
Figure 1.

One cause of this fall is the diminishing price of imported
oil versus the domestic price. As this price gap narrows,
coastal refineries switch to importing oil by tanker, which
entails much lower transport costs per barrel than rail
transport. Also, pipeline capacity from the Williston Basin
has gradually increased. Pipelines, including the recently
opened Dakota Access Pipeline, now have the capacity to
carry all of the Williston Basin's current production at
lower cost than rail.

According to the North Dakota Pipeline Authority, at the
peak of crude-by-rail volumes during fall 2014, railroads
were carrying away 60% of the Williston Basin's
production, while pipelines transported about 35%. In June
2017, railroads carried 7%, while pipelines carried 78%; the
remaining 15% was refined locally or trucked to Canada.
An oil train with 100 tank cars carries 70,000 barrels, so as
volume declined by more than 800,000 barrels per day, the
required number of trains has fallen from approximately 14
per day in the fall of 2014 to about three per day at present.


As Figure 2 indicates, most of the decline in rail volumes
has occurred in movements of North Dakota oil to East
Coast refineries. Movement of North Dakota oil by rail to
West Coast refineries has remained relatively steady, as
there is no pipeline available. The United States continues
to import Canadian oil by rail, most of which is destined for
refineries on the Gulf Coast.

The FAST Act, enacted at a time when crude by rail
volumes were three times greater than they are today, set
deadlines for DOT to issue a number of regulations
affecting transportation of oil by rail. Some of these
proposed regulatory changes are still pending, and the
