What H.R. 1366 does (and the Senate companion)

Procedural Viability Check (Rubric)

Composite viability score

Score: 3 / 5

Why 3: Friendly committees in both chambers and a bipartisan Senate companion create a plausible path, but the 60‑vote Senate hurdle and crowded December floor favor packaging over a stand‑alone vote.

Most realistic paths to enactment

1. Fold into a bipartisan “lands” or public‑lands title assembled by Senate ENR, then ride a year‑end vehicle. Precedent: large lands packages have moved on big bipartisan bills. [14]Wikipedia — John D. Dingell Jr. Conservation, Management, and Recreation Act
2. Attach to NDAA in conference or a managers’ package if scope is kept narrow/technical. Past NDAAs have carried public‑lands provisions. [15]The Conservation Alliance — Can Public Lands Bills Get a Ride with a Defense Bi…
3. Ride an Interior–Environment minibus/omnibus or a catch‑all CR/omni if leadership needs cross‑party sweeteners late in the process. (General practice; no unique citation required.)
4. Least likely: stand‑alone Senate floor time with cloture—possible, but eats precious hours and invites messaging amendments. Filibuster intact. [4]AP News — New Majority Leader Thune kicks off Senate session with pledge to pre…

Key risks and leverage points

• Budget points of order: creating a mandatory‑spending tap to IIJA §40704 could draw scrutiny if CBO scores net direct spending; keep the score de minimis. [8]Legal Information Institute — 30 U.S.C. §1245 - Abandoned hardrock mine reclama…[16]Congress.gov — All Info - H.R.1366 - 119th Congress: Mining Regulatory Clarity…
• Calendar compression: NDAA, FY26 wrap‑ups, and confirmations crowd December; this likely needs to hitch a ride. (General practice; no unique citation required.)
• Jurisdictional détente: keep language squarely within ENR/NR to avoid Commerce/EPW encroachment that complicates a manager’s package. (Procedural judgment.)

Vote dynamics snapshot

• House: Narrow GOP majority plus some Western Democrats (e.g., original co‑sponsor Horsford) should be enough if leadership grants floor time or folds it into a rule. [6]AP News — 119th Congress Latest: Mike Johnson narrowly reelected House speaker
• Senate: Base GOP support; path to 60 leans on mining‑state and Nevada Democrats—helped by the Cortez Masto‑led companion reported from ENR. [10]Congress.gov — Text - S.544 - 119th Congress: Mining Regulatory Clarity Act[11]Web search · turn 7 #1

Committee/chair leverage and procedural mechanics

• House: Westerman’s committee report filed; next gating item is Rules. A structured rule bundling minor resource items increases odds. [12]Congress.gov — Text - H.Res.13 (119th Congress): Electing Members to certain st…[1]Congress.gov — Text - H.R.1366 - 119th Congress: Mining Regulatory Clarity Act…
• Senate: ENR Chair Lee and Public Lands Subcommittee Chair Barrasso can slot the House bill or S.544 into a small lands package; floor managers then seek UC or add to a larger vehicle to avoid burning cloture time.

Bottom line

• Best shot is to move as part of a compact lands/resources package riding NDAA or an omni; stand‑alone is a heavy lift in a 60‑vote Senate. Composite: 3/5.

• Keep the text tight, emphasize AML funding and “regulatory clarity,” and line up Nevada delegation plus a few Interior‑West Democrats to clear cloture if needed. [10]Congress.gov — Text - S.544 - 119th Congress: Mining Regulatory Clarity Act
