The Montana Public Service Commission (PSC) is a quasi-judicial regulatory board of elected officials in the U.S. state of Montana.
The PSC regulates private, investor-owned natural gas, electric, telephone, water and private sewer companies doing business in Montana. In addition, the PSC regulates intrastate railroads and certain motor carriers hauling regulated commodities. The PSC oversees natural gas pipeline safety regulations. There is a major effort by the legislature and commissioners to put social-media companies under PSC jurisdiction as well.[1]
