Wolverine is required to have a thorough emergency response plan and the resources available to fund a worst-case scenario clean-up effort. The plan must be reviewed and approved by the Pipeline and Hazardous Materials Safety Administration (PHMSA).

Various federal, state and local emergency planning officials and agencies are involved in Wolverine’s preparation, training, and emergency response drills. The incident command structure that is utilized to manage any emergency situation aligns with the agency response protocols and therefore provides effective, efficient and integrated responses.

A standard and detailed response protocol is laid out in this four-step process:

  1. Secure the safety of the community and our employees
  2. Contain the release promptly
  3. Protect sensitive environmental areas
  4. Manage the incident and communicate effectively to all affected or involved

Recovery and clean-up are fundamental to the response efforts, but avoiding and preventing releases is Wolverine’s first priority.

Please call us — or your local law enforcement agency — to report any unusual activity in our pipeline ROW or any unauthorized entry into our facilities.

Signs of a Release


  • A pool of liquid on the ground
  • A rainbow sheen on water
  • Continuous bubbling in water
  • A dense white cloud or fog
  • Discolored or dead vegetation
  • Dirt or water being blown in the air


  • An unusual hissing or roaring noise


  • An unusual odor such as gasoline, sulfur or a rotten egg smell

Pipeline leaks are unusual, but do occur. The most common cause of pipeline incidents is excavation-related activities. We encourage everyone to be familiar with where pipelines are located, understand the signs and conditions of a possible leak, and know what actions to take.
