Marathon Petroleum Corp began restarting its 585,000 bpd refining complex in Galveston Bay that has been shuttered for more than a month now, according to Reuters sources.

The complex—America’s second-largest refinery after Motiva–was shut on May 23rd as part of a massive overhaul.

Marathon did not confirm the plans to restart, but the sources indicate that its 225,000 bpd Pipestill 3B crude distillation unit will be back in production sometime early next week. Pipestill 3B is one of two units tasked with breaking down crude oil into feedstocks for the remaining production units, which are also shuttered.

Some of those units, according to the sources, are expected to be back up by the end of this month.

The refinery overhaul was supposed to take place in March, but Marathon pushed back the work in order to prevent the spread of the coronavirus by the large number of contract workers that the work would require.
