It means that this airport cannot be used as an alternate for an IFR flight
plan. It can be used as the primary destination; however, it can not be
used as an alternate. Keep in mind, alternate airports are only required in
certain weather conditions.

It means it can't be the legally required alternate for filing a flight plan.
An alternate is required when any of the following is true:

1. The weather forecast for the ETA +/- hour isn't going to be 2000' and 3 miles
(1-2-3) rule.
2. The destination has no published approach.

In addition to the alternate NA restrictions, the alternate must be served
by an approach you are equipped for that does not involve GPS.

Of course, all of this only applies to the legal requirements for filing a plan
and computing the required fuel. Where you actually go if you can't get
into your destination is unaffected by what you put down as an alternate.
