Critical Mineral Dominance Act

What this measure contains

Critical Mineral Dominance Act This bill directs the Department of the Interior to address mineral supply chain vulnerabilities, including by accelerating and expanding mineral production on federal land (i.e., National Forest System land, public lands, and any land that may be leased for the exploration, development, or production of hardrock minerals). Interior must (1) identify priority mining projects on federal lands that can be immediately approved, and (2) take all necessary and appropriate steps to expedite those projects. Interior must also identify active, inactive, or proposed mining projects on federal land that have the potential to (1) increase production of hardrock minerals or their byproducts, (2) expand existing operations to include such byproducts, or (3) produce hardrock minerals from mine tailings or coal byproducts. Further, Interior must identify certain federal land with potential for hardrock mining. Interior must prioritize identifying land where a mining project (1) can most quickly be fully permitted and operational, and (2) would have the greatest potential effect on the robustness of the domestic mineral supply chain. Interior must (1) suspend, revise, or rescind agency actions that place undue burdens on mining projects; (2) recommend changes to current law necessary to expand U.S. production of hardrock minerals; and (3) review state and local laws that impede development of domestic mining and mineral exploration projects. Interior must also report on the dollar value and overall economic impact of the United States' reliance on imports of certain mineral commodities. Finally, Interior must prioritize efforts to accelerate geologic mapping.

Legislative path

Each stage below is a House or Senate floor decision: every recorded roll call on this measure, plus passage by voice vote or unanimous consent, which records no individual votes. Each stage shows the latest version published before that day; the chamber may have voted on an amended text. Roll calls name every member. A member's row follows their votes, and a highlighted vote marks where they voted for advancing the measure at one stage and against it at another (passage, cloture, motions to proceed, agreeing to the other chamber's version). Amendments and motions such as recommit or table don't count as a change, because an aye there isn't a vote for the measure.
