Marathon Petroleum Corporation

Profile

Summary

Marathon Petroleum is a fossil fuel company headquartered in Findlay, Ohio, that was created by the merger of three companies Marathon Oil (previously Ohio Oil Company), Ashland Refining and Tesoro Refining. The merged company is the largest producer of refined petroleum products in the United States, with 16 refineries across the country including the Galveston Bay Refinery in Texas and the Garyville Refinery in Louisiana’s Cancer Alley, two of the three biggest refineries in the country.* The Michigan and Louisiana refineries are located in major industrial zones with dozens of other polluting facilities and have been protested regularly by local communities who have suffered serious breathing problems and high cancer rates. In 2020, Marathon agreed to pay out $360,000 for air pollution at the Detroit refinery while several workers were hospitalized in a major explosion at the Garyville refinery in February 2022. Additionally the Texas City, Texas, refinery experienced a large oil leak from a storage tank as well as a hydrogen fluoride leak in 2021 that injured several workers.
