ME I sit down wind of their ethanol plant all day, smells like a brewery.
MTBE remains the required additive by the regulatory authority in many markets.
Moreover, ethanol production is insufficient to replace MTBE in all markets.
And, finally, neither MTBE nor ethanol contribute to the goal of cleaner air. Automobiles built since the early nineties do not need an oxygenated fuel to reduce hydrocarbon emissions to the required standard. All that MTBE and ethanol accomplish is to a.) increase the cost of gasoline by about 15 cents per gallon, where it is mandated and b.) reduce mpg by about 15-20%.
The Clean Air Act foisted this vile, unwanted (and unnecessary) stuff off on us. Nobody but Congress and the EPA is responsible for this horrid unintended consequence. The Act should be repealed forthwith.
