Also known as:
The San Francisco refinery was a medium sized high complexity refinery comprised of two integrated sites (Rodeo and Santa Maria) 200 miles apart in Calfornia in the US. The Santa Maria site was located near the coast between San Luis Obispo and Santa Maria in Arroyo Grande. The Rodeo site was located in the San Francisco Bay area. The two sites were joined by a 200 mile pipeline that moved unfinished products from Santa Maria to Rodeo.
The refinery was 100% owned and operated by Phillips 66.
The refinery processed a mix of heavy sour and light sweet crude. Crude was supplied both from pipelines connecting to onshore California production and imports by water.
in 2024 Phillips 66 permanently idled refining operations at both sites and converted the Rodeo site into a 800 million ga/y renewable diesel plant processing waste and vegetable oils, using some of the existing hydrocracking and logistics capacity. Existing crude pipelines were also be idled.
