Senate Bill 623 introduces a new regulatory framework for the issuance of permits for mining sulfide ore bodies in Wisconsin. The bill amends existing law by adding a new section, 293.50, which establishes a moratorium on the issuance of such permits until specific conditions are met. These conditions require the Department of Natural Resources (DNR) to confirm that a mining operation in a similar sulfide ore body in the United States or Canada has successfully operated for at least 10 years without polluting groundwater or surface water, and that a similar mine has been closed for at least 10 years without causing pollution.

Additionally, the bill amends section 293.49 (1) (a) to reference the new section 293.50, ensuring that the DNR cannot issue permits for sulfide ore mining without satisfying the outlined criteria. This legislative change aims to enhance environmental protections by ensuring that mining operations do not pose a risk to water quality, particularly concerning acid drainage and heavy metal release.
