I am happy to confirm the legal detail of the system to the noble Lord in writing, but my understanding is that the operator of the site would bear the responsibility. That is precisely why we have built in the relative decommissioning costs. The fund will have to be established and the operator will have to show that the ability is there to decommission the relevant pipe work, et cetera. I assume that that assurance and other long-term effects will also be built into that condition, but I will be very happy to confirm that in writing to the noble Lord.
