"BP Plc said the wastewater sediment discharge from its Whiting, Indiana refinery returned to permitted levels on Thursday, after several days of exceeding allowed amounts due an upset at a wastewater treatment plant.
'The refinery’s total suspended solids (TSS) returned to permitted levels on Aug. 4,' BP spokesman Michael Abendhoff said in an emailed statement. 'BP is working to safely return the refinery to normal operations as soon as possible and continues to monitor the situation closely.'"
