Fuel supply disruptions trigger emergencies in the Midwest.
A combination of fuel supply disruptions and winter weather conditions is significantly affecting the supply chain in the U.S. Midwest. Since November 27, operations on Enterprise’s pipeline system have been limited, particularly impacting terminals in Wisconsin and neighboring states, according to Wisconsin officials.
The reduced fuel flow has increased demand, especially for residential heating fuel. Added to this are extended wait times at Wisconsin terminals and the need to transport fuel long distances by road, factors that further complicate the logistical situation.
Fuel Emergency: hours-of-service exemption
In response, Wisconsin is maintaining a fuel emergency in effect through January 2, which grants a temporary hours-of-service exemption for carriers and drivers transporting residential heating fuel. The measure applies on all state highways, though those hauling such fuel on behalf of others must have the required authorization to operate in Wisconsin.
Iowa has also declared an emergency due to fuel supply issues. Chief concerns include timely access to heating products, such as propane, in rural areas. In Iowa, the hours-of-service exemption will remain in effect until January 3 and covers the transportation of propane, heating diesel, natural gas, and other fuels intended for residential, agricultural, and commercial use. The order applies on all state roads and does not require drivers to carry a copy of it.
Regarding fuel prices, recent data show that as of Monday, December 8, a gallon of diesel cost $3.57 in both Wisconsin and Iowa, according to ProMiles.com. Meanwhile, AAA reported on December 9 average prices of $3.528 in Iowa and $3.542 in Wisconsin. Regionally, the Energy Information Administration’s weekly report placed the Midwest’s average fuel price at $3.635.
Additional requests denied
Amid these emergencies, Wisconsin-based contractor Northern Clearing requested that the Federal Motor Carrier Safety Administration (FMCSA) extend the hours-of-service exemption. The company argued that the current timeframe does not cover long-term infrastructure rehabilitation needs once the immediate threat subsides. However, the FMCSA denied the request, citing a lack of clarity and insufficient evidence.
The Midwest continues to monitor the impact of these disruptions as officials assess the need for further support measures to ensure fuel supply during the heart of the winter season.
