Usually you don’t have to worry about interference caused to stations of your own Administration.
According to 4.3.7.1 you should verify if any stations of other Administrations have an Eu increase of 0.5 dB or more.

Eu Ref : Eu calculated at the time the assignment entered the Plan (n/a if not yet RECORDED)
NFS = Fs received + PR
n/c : Eu is not calculated (n/c) for the case Nuisance FS is more than 10dB (user selectable) below Eu Ref
