LAUREL, MT - The oil leak prompted the evacuation of several residents along the Yellowstone River.
Firefighters evacuated residents on Thiel Road in Laurel toward Duck Creek Road and out to Blaine's Trailer Court.
Laurel Volunteer Fire Department Chief Brent Peters says about 140 were evacuated in the Laurel area.
Residents were back in their homes by 5 am.
ExxonMobil Pipeline Area Superintendent Jim Montgomerey says it is not known what caused the leak.
He says it's possible a cause may not be determined until the river levels recede.
The pipeline starts at Silver Tip in the Belfry area, runs through Laurel, and then the ExxonMobil Refinery in Lockwood.
Montgomerey said the pipeline was build in 1949 and this is the first time it's had a leak.
She advised if anyone has any problems...it's best to stay indoors.
