The 1,780-acre Santa Maria Refinery, located adjacent to State Highway 1 on the Nipomo Mesa, has been in operation for nearly 60 years. Only about 200 acres, or roughly 11 percent of the land, is used for company operations. The remainder is grazed by cattle, held as open space or used as a preservation area for wildlife in the Nipomo Dunes.

As an important part of California's energy infrastructure, our refinery processes about 44,500 barrels of crude oil per day. The facility is also an important part of the local economy, employing 140 full-time Phillips 66 workers as well as our specialized contractors. We continually reinvest in and upgrade our facility to utilize changing technologies that generate safe and environmentally sound operations.

Our primary function at the Santa Maria refining facility is to convert heavy crude oil into high quality feedstock for further processing into gasoline, diesel and jet fuel. Crude oil is brought by pipeline into the facility from suppliers all over California's Central Coast region. The high quality feedstock produced at Santa Maria is sent by pipeline to our refining facility in Rodeo, CA for finishing into marketable petroleum products.

Our only finished products are petroleum coke (carbon) and sulfur. In fact, many local stores in San Luis Obispo County sell fertilizer made from our sulfur. Petroleum coke is used for a variety of purposes including phosphorus production, metals extraction and fuel.

An Integral Part of the Community

Maria Refinery is passionate about local causes in the areas of education, public safety and environmental causes. We commit funds to local organizations and our employees step up as active volunteers. You'll see us at Nipomo High School football games, picking up trash on the Mesa and sponsoring women's basketball programs at Cuesta College. The Santa Maria Refinery's staff helps with chamber of commerce programs, toy drives and fundraisers. We are part of the community, and we use our time and funds to improve lives here.
