History

USOR was organized in 1952 as a privately held corporation, then named Pacific Oil & Refining Co. The president of the company at that time was Dr. Ernest Lyder. The company was formed for purposes of building an oil refinery in the Pacific Northwest

. In 1954, the refinery's present site in Tacoma was purchased, and in 1955 its name was changed to U.S. Oil & Refining Co.

Construction of the initial facility, a 5000 oilbbl/d (stream) refinery, began during the summer of 1955. Construction was completed in mid-1957. By the end of that year, the refinery was in full operation. Chico Marx

A second crude unit, capable of processing heavy crude oil
Heavy crude oil
Heavy crude oil or extra heavy crude oil is any type of crude oil which does not flow easily. It is referred to as "heavy" because its density or specific gravity is higher than that of light crude oil. Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°.Extra...

USOR receives all of its crude oil by vessel at its dock. The refinery has storage capacity for approximately one million barrels of crude oil and one million barrels of refined petroleum products. Projects are currently underway (2007) to build an additional 500000 barrels (79,493.6 m³) of crude oil and 250000 barrels (39,746.8 m³) of product storage capacity. Product distribution facilities include truck & trailer, marine and rail loading for fuels and asphalt in Tacoma, and deliveries of jet fuel via pipeline.
