UPDATE: The City of Detroit has given the all clear and says that no further emissions are expected
The City of Detroit is recommending residents stay indoors Friday due to possible odor emission during Marathon repair work.
On Feb. 3, people across metro Detroit smelled a gas odor that was permeating from a Marathon Petroleum refinery. The odor was caused by a flare at the refinery that was not properly functioning.
Marathon officials said they plan to begin repairs to the malfunctioning flare Friday afternoon.
"As a precautionary measure, we will continue air monitoring for several hours after we de-activate the flare, in case there is any residual gas in the flare during the final de-activation process. We have notified local emergency response agencies of our plans," officials said.
