Freight rail strike could jeopardize fuel supplies nationwide, business groups say

She said she had nothing to report on that score but that the administration has been in “regular communication with Congress” and that “when the president has made a decision on this, if he makes a decision on this, you’ll hear from him.”

She noted that Biden has been “directly involved in the process and has been engaged with his team” and Congress “in case resolving the issue falls to them, as it has 18 times in the last 60 years.”

Coming disruptions: NATSO, together with SIGMA, a trade group for fuel marketers, warned that the availability of ethanol and diesel exhaust fluid could be disrupted if a strike or lockout shut down the nation’s railroads.

All diesel machines that are built with more than 74 horsepower are required to have a system to reduce pollution, and that system uses diesel exhaust fluid, which is made from water and urea. Sixty to 70 percent of ethanol transport happens on rail. It cannot be transported in oil pipelines because of its alcohol content.

“The U.S. economy in many ways revolves around transportation fuel, and if the necessary components to that fuel cannot get to where they are needed, the market impact will be drastic,” Neuman said in a statement. “A prolonged railroad shutdown will constrain the nation’s fuel supply by disrupting the availability of ethanol, which is often an essential component of gasoline, and diesel exhaust fluid, which most heavy-duty trucks need to run.”

What’s next: The railroads and the four unions that have rejected the latest contract offers have until Dec. 9 to negotiate a new deal. If an agreement can’t be reached in the next few days, railroads are likely to pre-emptively stop shipping sensitive materials like ethanol and urea so that they are not stranded once a shutdown happens.
