Asking what to do in case of GA to the ATC is the best thing to do.
As a note, in ATIS information specifies that there is a particular approach procedure in use, usually. This makes me think that the ATC is prepared for that kind of procedure in the event of go arounds, so it would be safe, in my opinion, to do the procedure of the plate.
Of course, ATC will give you specific instructions in most of the cases. If they don't, inform ATC you are doing the approach procedure just in case.
