Thank you very much.
We have some regulatory requirements right now. We call them setbacks from residences, and depending on the hydrogen sulphide content of the gas, there's a different distance that we require wells to be set back. Those are established from a longstanding review of the safety issues that have occurred with that distance. We also have a policy setback, we'll call it, which is not regulatory in nature. Right now I think our closest wells we have to residences are in the order of 300 metres distance to a residence. Part of the setbacks are probably more distance-related to issues like noise, light, for drilling. Those kinds of things create more of a setback than the actual safety setback for hydrogen sulphide gas.
