Anacortes Refineries, Washington

Two adjacent refineries are located on March Point, in Anacortes. One is operated by the Tesoro Petroleum Corporation, and a larger one is operated by Shell. Crude, processed at the plants, comes primarily from Alaska's North Slope, arriving by tankers making the trip from the Alaska pipeline terminus at Valdez, and also from Canada, via a pipeline connected to the oil fields of Alberta. The refineries consume a combined 255,000 barrels of crude per day, producing gasoline, propane, diesel, and other fuels for markets mostly within Washington state.
