   DAVENPORT, FL (DTN) -- Marathon Petroleum reported a flaring event at its 
631,000 bpd Galveston Bay refinery, the largest refinery in the United States, 
in Texas City, Texas, after a compressor trip, according to a filing with the 
Texas Commission on Environmental Quality.

   The event occurred between 1:29 a.m. and ended at 2:49 a.m. CT on Sunday 
(7/5), as per the filing made the same day.

   According to the report, a compressor trip at the refinery's Power 2 unit 
resulted in a flaring through Flare 2. The event released an estimated 763 
pounds of sulfur dioxide, based on engineering estimates and continuous 
emissions monitoring system data.

   The company said the compressor was restarted, and flaring stopped shortly 
afterward.

   The refinery primarily produces gasoline, diesel and jet fuel.

   DTN reached out to Marathon Petroleum for additional details but did not get 
an immediate response.
