Most Cat II and Cat III approaches can land in fog.

I read a report about a local airport with this statement:

"With existing Instrument Landing System (ILS) technology, inclement
weather, such as fog, is not a material obstacle to commercial service
operations."

I was under the impression that the FAA says fog is 1/4 mile
visibility. Can anyone legally land in fog?
