GREAT FALLS — An oil pipeline spilled crude oil on about 4 acres (1.6 hectares) of private property southeast of Great Falls, near Belt.
ABC Fox Montana reports the spill from the Phillips 66 pipeline happened on Nov. 14.
Cleanup has included vacuuming up spilled oil and removing contaminated soil.
State environmental regulators say the oil did not each surface or groundwater. Phillips 66 says there was no impact to people or wildlife.
The Department of Environmental Quality says Phillips 66 is complying with the state’s cleanup requirements and the pipeline has been repaired.
It was not immediately clear how much oil was spilled or how long it took to notice the leak.
