This is NEW in WA?????

In most areas of Washington state one can still find conventional
gasoline - I fill my Grumman with Chevon 92 octane at Everett WA.

Drat! I'm jealous.
Probably due to the climate and wind pattern, metro areas in WA did
not particularly have the air pollution problem back in the days when
ethanol was used merely as a oxygenate in winter blend to reduce CO
emission.

Yep. That's what we had for a decade or so.
Transporting corn ethanol all the way to Seattle from mid-west is
expensive. Maybe that's why they do this at Spokane. The gasoline
supply of Pacific NW on the other hand came from refineries along the
coast with crude oil shipped from Alaska on oil tankers (Remember
Exxon Valdez?).

Our pipelines come from Montana and Canada. In addition some fuel is
trucked from Columbia River barge terminals in the Tri-Cities.
