An unexpected shutdown at a neighboring refinery caused a two-hour sulfur dioxide leak at Great Lakes Solutions south plant early in the morning on Nov. 22, according to a report with the National Response Center.
At approximately 8:15 a.m., someone reported, “a release of sulfur dioxide from a flare stack due to a neighboring refinery that experienced a power failure forcing them to reroute to an emergency flare.”
In response, the feed streams were shut down, however, 9,053 pounds of the material were still released into the air during the flare, according to the report.
