I went to a BCI workshop in Penn. a number of years ago and the state wildlife agency there were very impressive. The gates, artificial habitats, state procurement of bat habitat (canoe creek state park for example has the old church that houses a maternity colony). They would be another resource to check with.
The comment about OSM may be helpful, but the state divisions of reclamation would have more information. I used to do some of the Virginia bat habitat evaluations for abandoned mines, which just looked at potential habitat conditions (and cost). Caves have many more aspects to be considered in an evaluation.
