Around 10:40 a.m. this morning a hydrocarbon leak at the Marathon Petroleum Refinery in Mandan was detected.
The leak was found in one of the refinery’s process units prompting all non-essential employees to be evacuated as a routine precaution according to Government and Public Affairs Manager Ron Day.
The company is in the process of depressurizing the unit right now.
According to Day, this particular leak was basically propane.
Day says workers should be able to re-enter the plant shortly.
