Comments on Michael Downing's arguments in his comments on "Shenhua mine’s water uncertainty means we should proceed with caution", 24/07/2015
Why take the figure of a "best estimate" of the cost for rehabilitation of a mine site and double it and apply a license fee to accumulate that figure, as you argued? Why double the best estimate? Is that a scientific approach, or an arbitrary impost?
Isn't your argument a layer of more red types?
Further, isn't it the case that the responsibility for rehabilitation of a mine is for the miner to do? If that is the case, are you advocate that the responsibility of rehabilitation be transferred to the government that would impose the extra license fee?
