119 · HR 1366 Mining Regulatory Clarity Act
H.R. 1366 (Mining Regulatory Clarity Act) would explicitly allow hardrock mines on federal land to locate multiple five‑acre mill sites when “reasonably necessary,” and channel the associated maintenance fees into a new Abandoned Hardrock Mine Fund to support cleanup work. It has been reported from the House Natural Resources Committee and placed on the Union Calendar, awaiting House floor action.
Public Summary: Mining Regulatory Clarity Act (H.R. 1366)
A quick, plain‑language overview for voters. Neutral, factual, and concise.
Headline Summary: Lets hardrock mines use multiple small support areas on federal land (for waste rock, tailings, and facilities) and directs the related fees to an abandoned mine cleanup fund.
What It Does: The bill clarifies that a mine on federal land may locate as many five‑acre “mill sites” as are reasonably necessary for operations, subject to an approved plan from the Interior or Agriculture Departments. A mill site does not grant mineral rights and cannot be patented (i.e., purchased outright). Mill sites may sit on the same tract as an existing mining claim. The bill also creates an Abandoned Hardrock Mine Fund in the U.S. Treasury and deposits claim‑maintenance fees collected from these mill sites into that fund to help pay for cleanup of abandoned hardrock mines under existing law.
Why It Matters: Supporters say clearer rules could speed permitting and provide certainty for mine planning, while also generating steady funding for cleaning up old hardrock mine sites. Opponents worry that allowing multiple mill sites could expand waste storage footprints on public lands and increase environmental risks near communities and sensitive habitats.
Who’s For It:
- Lead sponsors: Rep. Mark Amodei (R‑NV) and Rep. Steven Horsford (D‑NV).
- Additional sponsor: Rep. Nicholas Begich (R‑AK).
- Backers generally argue it clarifies long‑debated mill‑site rules, aligns law with modern mine layouts, and helps fund abandoned‑mine cleanup without new taxes.
Who’s Against It:
- Lawmakers and advocacy groups focused on public‑lands conservation and water quality may oppose expanding mill‑site authority, citing potential impacts from waste rock and tailings.
- Some also argue broader mining‑law reforms (like royalties or stronger environmental safeguards) should come before expanding siting flexibility.
What’s Next: As of November 25, 2025, the bill was reported (amended) by the House Natural Resources Committee and placed on the Union Calendar (No. 336). The next step is potential debate and votes by the full House; if it passes, the bill would move to the Senate.
