The latest: Motiva refinery begins initial startup phase

Motiva's Port Arthur Refinery is in the final phases of equipment assessments and initial phases of refinery startup, the company announced in a statement on Tuesday. "We expect the refinery to initially return to approximately 40 percent production by the end of this weekend, provided that the final assessments meet our operational standards," the statement said. "We continue to work closely with state, local and federal officials as well as disaster relief organizations to address storm impacts on our business and to aid our communities in their recovery. Our highest priority remains the safety of our employees and community.” Tropical Storm Harvey forced Motiva Enterprises, owned by Saudi Arabia's Aramco, to start a controlled shutdown of the Port Arthur refinery on Aug. 30. Motiva Port Arthur Refinery is the nation's largest refinery. It churns through more than 600,000 barrels of crude oil a day to produce gasoline and other petrochemicals.
