The Refinery produces motor vehicle gasoline and other petroleum products. The Project involves modifications to the Refinery to enable it to produce gasoline that complies with the Phase 3 Reformulated Gasoline regulations promulgated by the California Air Resources Board. Among other things, these regulations prohibit the use of MTBE in gasoline in California effective December 31, 2002. The Project inlcudes modifications to existing processing facilities, including modifications to (i) the naphtha recycle process, (ii) the dimersol unit, (iii) the cat naphtha splitter tower, (iv) the light cat naphtha hydrofiner, and (v) the MTBE/alkylation tower. In addition, equipment will be converted or installed to allow the Refinery to use ethanol as an oxygenate in gasoline. In particular, one tank currently used to store methanol will be used to store ethanol, blending skids will be installed at the marketing terminal to allow in-line blending of ethanol and gasoline blendstock, and a new pipeline will be built to connect the ethanol storage tank to the blending skids. The modifications described herin will use some existing tanks, piping, and truck loading system, and will also use new facilities, inlcuding pumps, instrumentation, vessel internal hardware, and piping, all of which will be integrated into the existing Refinery. Additionally, some processing equipment at the existing MTBE Production Unit will be removed from service, emptied and preserved for potential future use.
