About pipelines

According to the U.S. Department of Transportation, pipelines are the safest and most efficient means of transporting energy resources. Statistics from the National Transportation Safety Board show pipelines make up less than one one-hundredth of one percent (0.0001%) of all transportation accidents in the U.S.

Flint Hills Resources monitors pipelines 24 hours a day, seven days a week at our pipeline control center and through regularly scheduled aerial and walking patrols. We also perform in-line inspections on a regular basis to ensure the safety and reliability of the system.

State and federal jurisdictions oversee pipelines. Interstate pipelines are regulated by the Pipelines and Hazardous Materials Safety Administration (PHMSA). The Minnesota Office of Pipeline Safety (MNOPS) and Minnesota Public Utilities Commission (MPUC) oversee the MPL system.
