Work on several units was completed as of July 14, with those units scheduled to resume operations in a July 15-16 timeframe, ORPIC said in a notice posted to its Facebook page.
While the units will begin the restart process, it could take up to a week before the units return to normal operational levels, as is standard with refinery start-ups, the company said.
No details were disclosed regarding either the nature of the planned maintenance nor the units involved.
