The rule that has been waived was one that restricted sale of E15 in the summer time. Ever since last summer up to now, the rule has not been in effect since it is not summer, and E15 could be sold. The market should favor a shift to alcohol when the price of petroleum is high, but this hasn't been a sensible market.
In any case, the change allows whatever is happening now to continue past June 1 and through this summer.
