Biden intends to promote mining of minerals needed for batteries. Before new mines start, we must replace the old law that almost guarantees the mine will be left leaking pollution for decades, or millennia.

The obvious step is to require the mine, before it operates, to put aside a bond to clean it up — and then pay during operation to increase that bond, since the cost will probably increase.

But even better would be to operate the mine in a way that reduces or avoids the source of pollution. Has anyone developed a way to do this?
