It's a solvable problem. The article mentions distilleries in California that have done so (likely because they're required to by the government there).

It's not that hard to make the warehouses relatively airtight and add a ventilation system that sends all the exhaust through a scrubber to remove the ethanol before exhausting to atmosphere. It's just that the local government there isn't requiring it and is instead allowing these negative externalities to be born by the residents, because the whiskey companies have more political power than these relatively poor residents.

Same as adding systems to capture sulfur in chimneys (which previously was causing acid rain), this seems like externalized cost that needs to be clamped down. The warehouses will need to eat the cost to capture the ethanol vapours.
