II. Protocols for Locating and Surveying Potential Hibernacula
Hibernacula (natural caves, mines, tunnels, and other underground workings) within the project area should be located using mineral literature (The Pennsylvania Cave Database, maps and records from the Office of Surface Mining, and the PA Bureau of Abandoned Mines) and properly investigated by a USFWS approved bat consultant.
Due to the increased bat activity around such sites and/or the presence of threatened and endangered species, Hibernacula of Concern on or within five miles of a proposed wind development site triggers bat monitoring efforts. The Pennsylvania Game Commission (PGC) will notify the developer if such a hibernaculum is known on or within five miles of the proposed project and the developer should enter into consultation with the PGC to determine if additional protection or investigation will be useful to siting turbines. The PGC may conduct a survey in or around the project area for potential hibernacula that are not currently known and survey them for the developer. In the event that the PGC survey results confirm a previously unknown hibernaculum the PGC will notify the Cooperator and further coordination will be required. If a mine is located and contains multiple entrances, then all the bats captured at each entrance will be added together to determine if the site qualifies as a Hibernaculum of Concern
PA cavers built, maintained and continually updated The Pennsylvania Cave Database; that information was shared with the Pennsylvania Game Commission to add in conservation issues, such as the windmill issue noted above. Could the PGC use it to contact cave owners? Absolutely, although a fair amount of the info would be out of date. If KY cavers have worked with state agencies in the past, that's certainly one route that the state would have such a list. Those organized cavers...I guess it's a bit late to debate whether or not this was a good idea.
I don't think there's a privacy issue here, though. The county probably already has your property published online, with a map, overhead satellite photo, your purchase price, your current and past taxes, and if you're up to date. If they don't, they're working on it. Some counties include details as small as the number of plumbing fixtures. I have two commodes, if anyone needs to know....
