Phillips 66 Company Santa Maria Refinery

About Us

The 1,644-acre Santa Maria Refinery, located adjacent to State Highway 1 on the Nipomo Mesa, has been in operation for more than 50 years.

Only about 200 acres 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 130 full-time workers in addition to our specialized contractors.

We continually reinvest in and upgrade our facility to utilize changing technologies that generate safe and environmentally sound operations.
