Yellowstone River Pipeline Failure
The U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) proposed $1.7 million in civil penalties against the ExxonMobil Pipeline Company for safety violations linked to a July 2011 pipeline rupture that spilled thousands of gallons of crude oil into the Yellowstone River in Montana. PHMSA alleged that ExxonMobil failed to properly address known seasonal flooding risks of its Silvertip pipeline and to implement measures that would have mitigated the spill. In addition, PHMSA alleged that ExxonMobil failed to establish written procedures for its staff to take prompt and effective action to protect the pipeline from floods and other natural disasters and to minimize the volume of oil released from any section along the pipeline’s system. In addition to the proposed fine, PHMSA issued a proposed compliance order, directing the operator to implement ongoing training for supervisory and control room personnel on emergency response procedures. In January 2015, PHMSA reduced the final penalty amount to slightly over $1 million.
