Oregon Public Utilities Commission
The Oregon Public Utility Commission (PUC) does participate with PHMSA in regulating the safety of natural gas pipelines in Oregon. Surprisingly the PUC does not participate or assume any responsibilities in the enforcement and inspection of interstate and intrastate pipelines like the Kinder Morgan Pipeline which are used to transport hazardous liquids. This is in sharp contrast to the State of Washington who actively participates in this area. There are 14 states that participate in more direct oversight.
