The Cherry Point Refinery, owned by BP, is the largest oil refinery in Washington (and was the 30th largest in the U.S. in 2015). It is located about 7 mi (11 km) south of Blaine and 8 mi (13 km) northwest of Ferndale,[1] a few miles south of the Canada–US border, on the Strait of Georgia between Birch Bay and Lummi Bay.
