I think what we would see is non-ethanol stations forgoing the incentives and charging a premium, knowing full well that consumers will flock to non-ethanol gas, even for an extra $1 per gallon or so.
This will put enough pressure on other stations to offer non-ethanol gas along side E15, price wars will ensue, and ethanol in any concentration may be marginalized as a practical fuel. Pushing the limits of ethanol dilution could, via the free market, kill "gasohol". Here's hoping!
Correct currently the waiver allows but does not require E15 however I suspect later on tax incentives, etc to be pushed hard to force E15 adoption rates.
