My Lords, I have a question for the Minister in this general area. Does he feel that this proposed regulatory environment would cover cases in which fracking companies pipe sea-water on to land and then either dispose of it on land or, indeed, discharge it back into the sea? If it does not, it should.
I have a brief comment on what the noble Lord, Lord Whitty, said. To be fair, almost any ground-water or well-water that is drawn in regions that are underlain by coal measures—and this is predominantly the case in Pennsylvania—have some methane in those waters.
