BP has announced plans to divest two of its US refineries and seek buyers for the Texas City, Texas, and the Carson, California, refineries. The company also plans to sell its associated integrated marketing business in southern California, Arizona, and Nevada, and if all regulatory and other approvals are in place, to have the sales complete by the end of 2012. The company has indicated it plans to focus any future downstream investment in the U.S. on improving and upgrading networks around its 100 per cent owned Whiting, Indiana and Cherry Point, Washington refineries, and its 50 per cent interest in the Toledo, Ohio refinery. The Carson refinery has a 265,000 bpd refining capacity and supplies approximately 25 per cent of Los Angeles gasoline demand while the Texas City refinery has 475,000 bpd refining capacity. However, the company intends to retain the Texas City Chemicals complex adjoining the refinery. While divesting itself of these properties, BP is carrying out a number of major investments in its other US refineries, including plans to transform its 405,000 bpd capacity Whiting refinery to increase its capability to process heavy Canadian crude and upgrade a clean diesel project at its 240,000 bpd Cherry Point refinery.
