In 1913, the Golden Eagle facility became the third oil refinery to be built in the area. It was located in the newly-created company town of Avon, immediately to the East of Martinez. A fourth refinery, built by the Shell Oil Company on land adjacent to the Martinez City limits, went online in January 1916. The Shell Oil refining facility is still operational today (Currently owned by PBF Energy), maintaining the position of Martinez as a significant petroleum processing center. The Golden Eagle Refinery (currently owned by Marathon Petroleum Company) was idled in April 2020 as a response to lower petroleum demand during the COVID-19 pandemic.
