411A:
2 miles, as printed on the approach chart...even more restrictive.
I think you might be confusing the standard CAT D circling visibility minimum of 2 s.m. with the TERPs containment area, which is 2.3 n.m.
If your Ops Specs states you must remain within 2 n.m. while doing CAT D CTL, that would not change the TERPs criteria by which your IAPs are constructed; that is, unless they are non-public (special) IAPs. Even with specials, the FAA would not reduce the circling protected airspace.
