The ConocoPhillips Ferndale Refinery is located on Puget Sound in Ferndale, Washington, about 20 miles south of the U.S.-Canada border. During 2007, the refinery completed an expansion that raised the crude oil capacity to 100 MBD. The refinery processes primarily light, low-sulfur crude oil. Ferndale operates a deepwater dock that is capable of accommodating tankers bringing Alaskan North Slope crude oil from Valdez, Alaska. It also receives Canadian crude oil via pipeline. The refinery produces transportation fuels, such as gasoline and diesel fuel. Other products include residual fuel oil supplying the northwest marine transportation market. Most refined products are distributed by pipeline and barge to major markets in the northwest United States.
