Instead of concentrating on a simple typo, I would suggest you pay more attention to the meaning of my post.
It, (the Notam) is Legit because it concerns the unavailability of a Runway which therefore is safety related.
The fact that the decision to make the runway unavailable might not be safety related is irrelevant as the consequences of that decision is safety related and is rightly notamed
I am simply saying that the notam is not the problem. It is the decision behind it that needs fighting. Once that is sorted, the notam will sort itself out.
