Michelda - several things come into play here.
1) Why not ask the airport themselves - they will know whether state regs permit use of mid-point as per EUOPS (Table 6a)
2) I would suggest that the airport management may need a kick up the backside if they are offering an ILS with no touchdown RVR in low vis when they could deploy an observer (same table)
3) If your Ops Manual does not have the mid-point alleviation you are stuck with CMV, but I would ask your ops dept. to put it in (if you are EUOPS)
Lastly, what sort of 'low vis' did you have in mind in your question?
