Senate Bill No. 1382, aimed at updating Minnesota's approach to managing nonferrous sulfide ore mining projects, proposes several significant changes to ensure that such mining activities meet stringent environmental standards. Here’s what the bill includes:

1. Policy for Mineral Development Update: The bill reaffirms Minnesota’s commitment to support mineral exploration and development while ensuring compliance with health and environmental protection standards.

2. Moratorium on Permits and Reviews: It introduces a moratorium, preventing environmental reviews and the issuance of permits for nonferrous sulfide ore projects unless it can be demonstrated that a similar mine has operated in the U.S. without causing environmental harm for at least a decade before and after its closure. This is to ensure that new mining projects do not commence unless they can historically prove their safety and environmental compliance.

3. Strict Definitions and Requirements:

   • Nonferrous Sulfide Ore is defined broadly, including metals like copper, nickel, and others that do not predominantly extract iron.
   • Mines must be in "similar environments" to those proposed for new projects in terms of climate and proximity to water bodies.

4. Requirement for Public Involvement: Before any preliminary decision on environmental reviews or permits, a public notice must be issued inviting comments. Additionally, if substantial evidence contrary to the proposed project's safety is presented, a contested case hearing must be held.

5. Permit Reevaluation: Any permits issued will need reevaluation and potential renewal every ten years, ensuring ongoing compliance with updated environmental standards.

6. Power and Responsibility of Commissioners:

   • The bill assigns significant responsibilities to both the commissioner of natural resources and the commissioner of the Minnesota Pollution Control Agency for enforcing these provisions.
   • They are tasked with comprehensive oversight, including the power to issue, modify, or deny permits based on detailed environmental assessments and public input.

7. Enhanced Pollution Control Measures: The bill amends existing statutes to allow for more stringent control on waste treatment and disposal, and it revises standards for new sources of pollution based on the best available technology and practices.

In summary, S.F. No. 1382 seeks to bolster Minnesota’s mineral resource policies by placing stricter environmental scrutiny on nonferrous sulfide ore mining, requiring proof of historical safety, enforcing regular permit reassessments, and ensuring significant public and governmental oversight before and during such mining projects.
