Suncor Energy Inc on Tuesday said that all affected units at its 85,000-barrel-per-day refinery in Sarnia, Ontario, have resumed standard operations following an operational issue.
“On-going community air monitoring indicates SO2 levels trending downwards and will remain in place as we work to return to standard operations,” the company said.
