In second paragraph, please read "starting this month in southern California and completing it by May. It will end its use of MTBE statewide in December 2003, which is the deadline established by California Governor Gray Davis. (Corrects time frame of MTBE elimination) A corrected version follows. SAN RAMON, Calif, Jan 8 (Reuters) - ChevronTexaco Corp. (NYSE:CVX - News) said on Wednesday it will stop using the groundwater polluting chemical MTBE in California gasoline, putting the company in compliance with a state-imposed deadline. Chevron will start phasing out the use of methyl tertiary butyl ether, or MTBE, starting this month in southern California and completing it by May. It will end its use of MTBE statewide in December, which is the deadline established by Governor Gray Davis. MTBE has been added to ultra-clean gasoline since 1979 to cut emissions, but has been banned in several states. Chevron will substitute corn-based ethanol for MTBE. Ethanol's opponents say the switch could lead to supply shortages and price spikes for gasoline in California, in part because of problems with sending ethanol through pipelines. More than half of California refiners have already begun to sell some CARBOB (California Air Resources Board Oxygenated Blend) the ethanol-blended gasoline that will be required staring in 2004. In July, ChevronTexaco and Exxon Mobil Corp (NYSE:XOM - News). (NYSE:XOM - News) agreed to pay $30 million in cash and pay the full cost of building and running a water treatment plant to clean MTBE and other contaminants from water wells owned by the city of Santa Monica, California. Phillips Petroleum Co. (NYSE:P - News) has already switched to ethanol in California and other refiners are also considering an early switch.
