(a) “Pollution" means degradation that results in any violation of any 7
environmental law as determined by an administrative proceeding, civil action, 8
criminal action, or other legal proceeding. For the purpose of this paragraph, 9
issuance of an order or acceptance of an agreement requiring corrective action or a 10
stipulated fine, forfeiture, or other penalty is considered a determination of a 11
violation, regardless of whether there is a finding or admission of liability.
(b) “Sulfide ore body" means a mineral deposit in which nonferrous metals are 13
mixed with sulfide minerals.
No city, village, town, or county may be held liable for any pollution within 2
its boundaries that is caused by the exploration, bulk sampling, mining, or 3
prospecting of a sulfide ore body, regardless of when the activity occurs or is 4
discovered or where the activity occurs, including whether the activity occurs on 5
property that is owned, either at the time of the activity or subsequently, by the city, 6
village, town, or county.”.
