Minnesota Statutes Related to Pipeline Safety 


Pipeline Permitting & Routing

The Minnesota Office of Pipeline Safety (MNOPS) acts as a regulatory agency ensuring Minnesota’s pipeline infrastructure is in compliance with applicable pipeline safety standards.  State Statutes do not give MNOPS regulatory oversight over pipeline routing and permitting.

State Statutes (Minnesota Statute 216G) do give routing and permitting authority to the Minnesota Public Utilities Commission (PUC) regarding the following:

  • Pipelines with a diameter of six inches or more that are designed to transport hazardous liquids like crude petroleum
  • Pipelines designed to carry natural gas and be operated at a pressure of more than 275 pounds per square inch

State Statutes do not apply to interstate natural gas pipelines regulated under the federal Natural Gas Act and to pipeline owners or operators who are defined as a natural gas public utility under Minnesota Statute 216B.02.  Rules for the administration of pipeline route permits are found in Minnesota Rules Chapter 7852. Routing and permitting of interstate natural gas pipelines fall under the authority of the Federal Energy Regulatory Commission (FERC).
