Procedural Viability Check (Rubric)

Score: 3/5 (see factor‑by‑factor reads).

Most likely paths to enactment (and timing)

1. Bundle into an early–mid 2026 ENR parks/lands package led out of the National Parks Subcommittee, moving on UC in the Senate and suspension in the House. Daines’ subcommittee is actively curating such dockets. [4]Congress.gov — Senate ENR Subcommittee on National Parks — Hearing (Dec. 9, 202…[9]Office of Sen. Steve Daines — Daines Chairs Senate National Parks Subcommittee…
2. If a broader “public lands” or outdoor‑recreation package gels, keep S.2708 intact but accept technical edits responsive to DOI’s prior concerns (e.g., designated operational partner authorities, surplus property transfers) to ease executive clearance. [8]U.S. Department of the Interior — DOI Statement on H.R. 9159 (Appalachian Trail…
3. House path: run through Natural Resources, target a noncontroversial markup and seek suspension time; factor in episodic rule‑vote turbulence when planning floor timing. [10]Congress.gov — H.Res. 13 (119th) — Electing Members to Standing Committees (Cha…[12]News result · turn 3 #12

Vote math and coalitions

• Natural coalition: Mid‑Atlantic/New England senators with Appalachian Trail constituencies + ENR institutionalists (Collins/Murkowski/Cassidy) + trail‑state Democrats; Tillis as co‑sponsor is a useful bridge. [5]Congress.gov — S.2708 — Appalachian Trail Centennial Act (Text)
• Potential friction points: statutory elevation of nongovernmental ‘Designated Operational Partner’ and property‑rights provisions drew a formal DOI objection in 2024; expect similar flags unless revised. [8]U.S. Department of the Interior — DOI Statement on H.R. 9159 (Appalachian Trail…
• House: Bipartisan appeal is credible, but floor control is volatile; aim for suspension with visible GOP and Dem co‑sponsors to minimize leadership risk. [6]Congress.gov — H.R. 5134 — Appalachian Trail Centennial Act (Overview)[12]News result · turn 3 #12

Bottom line

Composite viability score: 3/5. Senate‑origin and bipartisan sponsorship plus an ENR Subcommittee hearing are positives. But the bill is not reconciliation‑eligible, faces a 60‑vote Senate, and is best positioned as part of a 2026 parks/lands package after modest technical edits responsive to Interior concerns.
