Chevron U.S.A. Inc. announced today plans to build a major gasoline production unit at its refinery in Pascagoula, Miss. With environmental permits in place, construction of the Continuous Catalyst Regeneration (CCR) Project, estimated to cost around $500 million, is due to begin in early 2008 with completion anticipated by mid-2010. The new CCR unit will improve equipment reliability and utilization, and allow the refinery to optimize product yields. Gasoline production at the refinery is expected to increase by approximately 10 percent, or about 600,000 gallons per day.
