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.
