The Detroit refinery’s firefighters will conduct a fire-extinguisher class on Thursday, April 18. This may result in some visible smoke from the refinery property.
Michigan State Police is reminding the public that there will be a test of the state’s outdoor tornado warning sirens at 1 o’clock this afternoon, March 27. We are sharing this reminder so that there is no confusion with the refinery’s alarm. For more information, please access the following link:
Marathon Petroleum has begun startup activities at its Detroit refinery after conducting extensive safety testing. A normal part of startup activities includes flares that may be larger than they would be during day-to-day operations. This flaring is a safety measure that ensures materials fully combust. As the plant resumes full operations over the next week, flaring will return to normal levels.
Marathon Petroleum has completed the de-activation of the malfunctioning flare. There were no additional unexpected emissions during the process.
Marathon Petroleum continues to conduct air monitoring in nearby communities, and continues to share results with the Michigan Department of Environmental Quality, U.S. Environmental Protection Agency, and the City of Detroit’s Buildings, Safety, Engineering and Environmental Department. We plan to begin repairs to the malfunctioning flare this 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.
