HR1366-119

What This Bill Does

The Mining Regulatory Clarity Act amends Revised Statutes section 2337 to define mill site, operations, operator, plan of operations, and public land. When public land is needed for operations connected to a lode or placer claim within a proposed plan of operations, the proprietor may locate and include as many mill site claims as are reasonably necessary and may use or occupy public land under an approved plan. A single mill site may not exceed five acres, conveys no mineral rights, is not eligible for patenting, and may be located on a tract where the claimant already maintains a lode or placer claim. The bill preserves withdrawn-land, environmental, public-land, wilderness, historic-preservation, Endangered Species Act, and Surface Resources Act authorities. It also creates an Abandoned Hardrock Mine Fund in Treasury funded by claim maintenance fees on the new mill sites.

Who Benefits and How

Hardrock mining companies, lode claim operators, placer claim operators, mining project financiers, critical-minerals developers, mine plan engineers, and operators needing waste rock or tailings disposal benefit from clearer authority to use multiple mill sites when reasonably necessary for approved operations. Abandoned mine cleanup projects, federal land managers, states with legacy hardrock mine hazards, and communities near abandoned mines benefit from a dedicated fee-funded remediation account.

Who Bears the Burden and How

Mining operators locating new mill sites, Bureau of Land Management staff, Forest Service minerals administrators, Interior claim-maintenance fee staff, environmental reviewers, public-land users, conservation groups, and federal mine-remediation managers must administer additional mill-site locations, collect and deposit fees, review plans of operations, enforce five-acre and no-patent limits, apply savings clauses, and use fund balances for abandoned hardrock mine land remediation.

Key Provisions

• Defines mill site as public land reasonably necessary for waste rock, tailings disposal, or operations incident to mineral development or production under a plan of operations.
• Authorizes operators to locate as many mill site claims as are reasonably necessary for operations connected to lode or placer claims.
• Limits each mill site to five acres, denies mineral rights, bars patenting, and preserves validity of associated lode or placer claims.
• Preserves federal authority under public-land, mining, wilderness, park, endangered species, historic-preservation, and surface-resource laws.
• Establishes the Abandoned Hardrock Mine Fund in Treasury.
• Deposits claim maintenance fees from new mill sites into the fund for abandoned hardrock mine land remediation.
