The law allows other non-attainment areas that are not severe and serious to opt into the program. In some part of almost 17 states, areas are using reformulated gasoline. The people who opt in are required to stay in for a certain number of years for price stabilization. The people who are required to be in by law can't opt out. Some critics think the EPA may have miscalculated when it predicted a price increase of pennies per gallon.
Numerous things drive market prices.
That's what we need to determine. The overall performance of reformulated gasoline, which includes lower vapor pressures, which decline both the nitrogen oxide and the volatile organic compounds emissions from automobiles, has had a significant impact on ozone, and it's done it very cost-effectively. It's a good strategy. If we had any concern about these kinds of prices, obviously you would want to look at them, but we don't see how these prices can be derived solely in these changes in the formulations to have the gasoline burn more cleanly. The other thing to point out is this is also reducing air toxics that come from combustion of gasoline in vehicles.
