The Commerce City, Colorado refinery is a major asset, as noted in the article. This asset was merged from two refineries owned by ConocoPhillips and Valero. The Valero facility was apparently built by Bay Petroleum and subsequently passed through Tenneco, Asamera, and Total S.A. before Valero bought it.
