SACRAMENTO -- The California Air Resources Board (ARB) acted today to postpone by one year the mandated phase-out of MTBE in the State's gasoline.
"This action gives those refiners who are not ready to fully remove MTBE extra time to adjust to the phase-out and thereby protect California consumers from disrupted supplies and price spikes," said Dr. Alan Lloyd, ARB Chairman.
The ARB Board, meeting in Sacramento, voted to extend the MTBE phase-out deadline from December 31, 2002 to December 31, 2003. This was done as a result of the Governorís Executive Order D-52-02. The order directed ARB to postpone for one year the requirement to remove MTBE from Californiaís gasoline.
The Governorís original Executive Order, on March 25, 1999, ordered the removal of MTBE from gasoline by December 31, 2002 because MTBE was found to be contaminating some drinking water supplies.
MTBE or Methyl Tertiary-Butyl Ether was first added to Californiaís gasoline in the mid 1980ís to enhance octane. Its use was expanded in 1991 to control high winter carbon monoxide (CO) levels in some areas of the state. The program expanded, and MTBE has been added to most of California's gasoline since 1995, largely as a result of federal clean-air rules that require oxygenates (either MTBE or ethanol) in gasoline under the theory that they reduce emissions from motor vehicles.
California has submitted evidence to the U.S. Environmental Protection Agency (EPA) that the cleanest possible gasoline can be blended without the use of oxygenates. The stateís request for an EPA waiver from the oxygenate requirement was rejected last year. California is now pursuing a legal challenge to the EPAís decision.
By the end of 2002, the federal oxygen requirement will apply to about 80 percent of the gasoline sold in California.
Under the federal oxygenate requirement, the only viable alternative to MTBE is ethanol. However, the bulk of ethanol would have to be shipped in from out of state, adding to the expense of gasoline and leaving California open to supply disruptions.
Federal legislation, pending in Washington, would alter the requirement in 2004. On March 15, Governor Davis ordered the one-year extension to coordinate with the effective date of the proposed law and make sure the entire California refining industry is prepared for the changeover and avoid possible gasoline supply disruptions.
"We continue to hope that the federal government will take the path of sound science and release California from the oxygenate requirement," Dr. Lloyd said.
In addition to the one year extension allowing refiners to continue using MTBE, the Boardís action today also
made other technical adjustments to gasoline refining regulations in order to align them with the extension.
The Air Resources Board is a department of the California Environmental Protection Agency. ARB's mission is to promote and protect public health, welfare, and ecological resources through effective reduction of air pollutants while recognizing and considering effects on the economy. The ARB oversees all air pollution control efforts in California to attain and maintain health based air quality standards.
The energy challenge facing California is real. Every Californian needs to take immediate action to reduce energy consumption. For a list of simple ways you can reduce demand and cut your energy cost, see our website at http://www.arb.ca.gov.
