Yes, there has.
In the late 1960s and early 1970s there were approximately 10 wells drilled on Sable Island, including one in the middle. There were a number, I believe, on the west end of the island, and some of the remnants are still there. That's why one of the activities is still in here. This is to provide industry with access to those wellheads. What they do is cut them off below the surface, but because Sable Island is constantly shifting, it exposes those. The companies are still liable for anything that may happen as a result, so they need access to the island from time to time to check the status of those wellheads to see if any remedial action needs to be taken to ensure there is no impact on people's health, including visitors, as well as on the environment of the island.
