What does "a limited waiver on gasoline requirements" mean?
If I'm not mistaken, it means we can draw on winter fuel stocks now which normally cannot be sold until after September 15.  The summer stocks have anti-smog additives which the winter stocks don't  By letting us use winter stocks we can lessen the impact of the refinery outages while the refineries get back into operation.  It will mean a little addition smog in some areas, so there is some downside.
Thanks for the information, I thought it would be something like that.

I consider this is a litmus test for how Western civilization will deal with energy reductions in the coming years. And it does not bode well for the future. When push comes to shove, we'll burn dirty gasoline, do anything to keep the machines running, and to hell with the consequences. (Ah, we'll deal with that next year).

Shows how much weight the issues of environmental protection carry.
