Methyl Tert-Butyl Ether in Gasoline

The CAA Amendments of 1990 were signed into law by President George Bush in November 1990. The overall goal of the amendments was to reduce polluting emissions from all sources by a total of 57 billion pounds per annum when full implementation was achieved in 2005. The primary thrust of the legislation was completion of efforts begun under the CAA of 1970 and its 1977 amendments. The amendments directed the EPA to establish regulations to achieve the various principal goals including: reducing urban air pollution, controlling emissions from mobile sources, reducing or eliminating other air toxins, reducing

raded." The drawbacks of ethanol are relatively minor. It increases emission of the toxic pollutant acetaldehyde, but still produces overall reductions in air contamination, and, in water, it increases "the solubility of other gasoline contaminants' plumes allowing the to spread further." Ethanol's principal drawbacks are economic. It cannot be practically transported by pipeline and is only practically produced in areas where the raw materials are readily available, i.e., the Midwest. Since 74 percent of the demand for RFG and oxygenated fuels is on the East and West coasts, and ethanol is also more expensive to produce because it "requires additional processing to meet the volatility requirements" of RFG, its use would probably increase the costs of cleaner-burning fuels considerably. The Clinton administration, not unsusceptible itself to agricultural interests, proposed that the EPA require that "at least thirty percent of oxygenates in gasoline be renewable," which meant, in effect, a mandate for higher ethanol use since it is the primary fuel additive considered to be renewable, i.e., derived from organic sources. But the fate of ethanol will probably not be decided for some time as the debate over MTBE continues
