Santa Maria Refinery

About

The San Francisco refinery is composed of two facilities linked by a 200-mile pipeline. The Santa Maria facility is located in Arroyo Grande, Calif., while the Rodeo facility is in the San Francisco Bay area. The combined facilities have a total crude oil processing capacity of 120 MBD.

The refinery processes mainly heavy, high-sulfur crude oil. It receives crude oil from California and foreign sources by tanker.

Semi-refined products from the Santa Maria facility are sent by pipeline to the Rodeo facility for upgrading into finished petroleum products. A high proportion of the refinery‚Äôs production is transportation fuel, such as gasoline, diesel fuel and jet fuel. The refinery produces CARB gasoline using ethanol to meet government-mandated oxygenate requirements. The majority of refined products are distributed by pipeline, railcar, truck and barge to customers in California. [1]
