As informed, the refinery, located in Port Arthur, Texas, with 325,000 barrel capacity per day, has restored production at the 105,000-bpd Hydrocracking Unit 2.

However, Motiva said that the Port Arthur refinery would resume production at 40% capacity by Monday and it will need four to eight weeks to return to the maximum production.

In the meantime, the US Coast Guard, in cooperation with the US Environmental Protection Agency (EPA) and Texas regulators, are working to clean up oil spills caused by oil refineries, fuel terminals and other businesses flooding from Harvey.

Officials said they are not in position to know the exact amount of pollutants dispersed after Harvey, as some spills were already being cleaned up by the time they arrived.
