The Chevron Refinery Modernization Project (Modernization Project) would complete construction and begin operation of two of the Chevron Hydrogen and Energy Renewal Project major components: a replacement Hydrogen Plant, and a collection of new sulfur removal equipment improvements that remove naturally occurring sulfur contained in the feedstocks processed at the Facility. The Modernization Project also includes related infrastructure improvements to Facility piping, utility lines, and electrical systems. The Modernization Project includes several integral equipment components that would reduce air emissions from Facility operations (the Emission Reduction Project Components) and further Project Design Features proposed to avoid or minimize environmental impacts. The Project also includes a new Reliability Program, including new safety programs and several physical modifications including the replacement of 17 piping circuits in the Crude Unit. Reducing Project emissions would help meet Chevron's commitment of assuring that the Project would cause no net increase in emissions of criteria pollutants, greenhouse gases, and public health risks from air pollutants, when compared to the Facility emissions and operations that occurred during the baseline period of 2008 through 2010. Following issuance of all necessary approvals, Chevron proposes to complete Project construction within approximately 24 months. The City Council approved the Modernization Project on July 29, 2014.
