The fixed sites have Nothing to do with normal “AMA” fields. They are strictly referring to fields that are within a certain distance to Full scale airports, which they are more severly limiting the altitude ceiling.
Prior to this release ALL RC flying within the airspace of a full scale airport had to be approved on a case by case basis with the airport operating authority. With this new ruling, they are providing a blanket authority to allow any and All RC/drone operations within these “fixed sites” (full scale airports) with certain restrictions, most of which i have seen involve altitude limits below the 400’agl blanket limit for the Us.
So no, your local club doesnt need to be on this list UNLESS it falls within one of the FAA selected airspace restriction areas.
