Interesting.

When I was doing my research on ULPower engines (which can burn 100LL, but they would prefer non-leaded), there were very few airports who offered unleaded fuel (UL94). I think, San Carlos / KSQL was the only one I found?

I wonder what KRHV closure would mean for unleaded fuel? So everybody would just switch back to 100LL? How is that supposed to help?

Wouldn't be more practical (from the point of lead pollution) to enforce non-leaded fuels in those small airports instead? My cursory research shows that lot (?) of these light planes (and, perhaps, the majority of the trainer/weekend hobby aircrafts) would happily burn non-leaded fuel (UL94, for instance), with corresponding STC.

Definitely. It solves one problem.

It doesn't solve the "this airport takes space that could be used for parking lots" problem.
