Big West Oil

Big West Oil operates a refinery in Utah, supplying petroleum products used in transportation and industry. Its company overview describes a locally operated refining business serving the Intermountain West. The work links the processing of crude oil with the downstream products consumed by businesses and drivers. [1]

The company identifies North Salt Lake in its contact information. Its operation is distinct from a retail filling station: the refinery is part of the industrial supply chain that makes finished petroleum products available to other businesses. That gives Davis County a role in the region’s energy production and distribution infrastructure. [1] [2]

Big West says its North Salt Lake refinery was commissioned in 1948 and that the company itself was founded in 1985, so the refinery is older than today's operator. [3]
