Santa Maria Refinery

The Phillips 66 Santa Maria Refinery has operated on the Nipomo Mesa for nearly 60 years and employs approximately 200 people.

Phillips 66 is currently working with San Luis Obispo County and other government agencies to obtain permits to extend the existing rail spur within the refinery property. Information about the rail project is available on our Santa Maria Refinery Rail Project website. Project documents are available online on the SLO County’s Planning Department website.
