Propane Supply Disruptions Impact Midwest & Mid-Atlantic Regions

Editor’s Note: The following first appeared in the National Propane Gas Association’s (NPGA) The Bobtail. 

On November 19, 2025, an electric transformer at Marcus Hook Terminal suffered an incident which disabled the propane truck-loading rack for three days, and created lingering problems at the terminal. Since then, Energy Transfer Partners, the operator of the terminal, has been unable to pump propane from its storage caverns. Energy Transfer Partners declared force majeure at the terminal and instituted allocation, providing for 70% of contracted loads. Wait times at the terminal have been increasing, and given that the terminal is loading directly from the pipeline, the time to load is taking longer than normal. NPGA has been active with membership in the Mid-Atlantic, communicating with state leadership in the immediate aftermath of the incident, and informing the Federal Energy Regulatory Commission (FERC) and the Federal Motor Carrier Safety Administration (FMCSA). NPGA contacted rail carriers to supplement supply, who responded that customers should contact their representatives directly and extra capacity is available in the Mid-Atlantic to supply marketers by rail. NPGA is also engaged with FMCSA regarding a regional waiver given the impact on the Mid-Atlantic and New England and the uncertain timing of repair. 

On November 27, 2025, the Mid-America Pipeline (MAPL) suffered a leak in Kansas, leading to significant supply disruptions in Missouri, Iowa, Illinois and Wisconsin. NPGA staff immediately engaged with state leaders, marketers, FERC and FMCSA regarding the situation. Conversations with Enterprise Products Partners determined that the pipeline had been repaired on December 3, 2025, and that the pipeline repair only required approval from the Office of Pipeline Safety at the Pipeline and Hazardous Materials Safety Administration (PHMSA). NPGA has been working to expedite this approval, to resolve the outstanding supply disruption in the Midwest. Iowa and Wisconsin issued hours of service waivers for intrastate commercial driving. According to multiple sources, MAPL resumed normal service on December 5th, 2025.
