Sulfate water quality standards site-specific modifications approval during pendency of related rulemaking provision, reactive mine waste storage provision, and additional unemployment insurance benefits provision

This bill creates targeted unemployment benefits for workers laid off from the iron ore mining industry or related explosive manufacturing during March 15-June 15, 2025, due to significant workforce reductions (50%+ layoffs). Eligible workers must have exhausted regular unemployment benefits and meet standard eligibility requirements, receiving up to 26 weeks of additional benefits at their prior weekly rate. The bill also establishes standards for storing reactive mine waste to prevent water quality impacts, defining "reactive mine waste" as material causing sustained pH decreases in contact water. It is effective retroactively from March 15, 2025.
