The BP-Husky Refinery, an oil and gasoline refinery outside Toledo in the suburb of Oregon, got a $400 million upgrade.
The work took two years and 1,500 workers.
The project will make the refinery more efficient, less polluting and enable it to refine better grades of gasoline.
Right now the refinery gets most of its crude oil from Canada, but new sources of crude are starting to flow from Ohio itself, as well as Pennsylvania and West Virginia — from the Utica and Marcellus Shale.
The upgraded refinery has more flexibility to process different types of crude, including shale oil.
