Cemeteries in the Marcellus Shale Region of Western PA

Recently a number of cemeteries, including the Catholic Cemeteries Association cemeteries, in the Marcellus Shale region of southwestern Pennsylvania have signed leases with gas drillers.  Some of these cemeteries are in Allegheny County which is where the city of Pittsburgh is located.  Urban drilling?  The cemeteries claim that they will not permit the drillers to drill in developed sections of any cemetery.  The drillers will only be allowed to drill in not yet developed areas of cemeteries.  Think about that.  Do you think your buried loved ones would like that proximity.  How will the survivors of those buried find that acceptable.  Presumably all of the money from the leases goes to the cemeteries, not to the owners of the graves.  How much money is involved and who benefits from this money.  What will the cemeteries do with the money?  Probably buyers of graves did not have something like this in mind when they bought their graves.  My understanding is that un-/non-developed sections of cemeteries can only be used eventually for burial purposes.?
