1.15 		Subd. 2.Permit considerations. (a) The commissioner of natural resources must not 
1.16 	issue a permit under section 93.481 for mining a sulfide ore body until the commissioner

1.18 	commissioner, that a single example mine operated in a sulfide ore body, which, together 
1.19 	with the host rock, has a net acid generating potential in the United States or Canada:
1.20 	(1) operated for at least ten years without pollution of groundwater or surface water from 
1.21 	acid drainage at the tailings site or mine site or from the release of heavy metals; and

2.12 	environmental pollution from acid drainage at the tailings site or mine site or from the 
2.13 	release of heavy metals.
