Status and Context

- Bill: S. 2708, the "Appalachian Trail Centennial Act" (Kaine–Tillis), with a House companion H.R. 5134 (Beyer–Lawler).

• Institutional control: Republicans hold both chambers (Senate majority; House 220–215; Speaker Mike Johnson; Senate Majority Leader John Thune). Filibuster remains operative (60‑vote cloture).

• Issue landscape: Appalachian Trail spans 14 states and relies on the public‑private cooperative management model highlighted by ATC and NPS. [12]National Park Service — NPS article: A.T. spans 14 states / cooperative model[13]National Park Service — NPS: AT cooperative management & partners

Breakdown: Expected Support/Opposition by Party and Caucus

Anchor: current majorities (R Senate; R House) and corridor‑state politics around the A.T. [8]Wikipedia — 119th United States Congress (party control, leadership)

• Senate Democrats/Independents: Broadly favorable to trails/public‑lands measures; bill sponsor is Sen. Kaine and many corridor‑state Dems (e.g., Warner, Schumer, Gillibrand, Welch, Hassan, King) have natural constituency ties. Expect near‑unanimous support unless NGO authorities remain untouched. [5]Library of Congress — S.2708 - Appalachian Trail Centennial Act (Congress.gov)[12]National Park Service — NPS article: A.T. spans 14 states / cooperative model
• Senate Republicans: Mixed but workable. Lead GOP cosponsor (Tillis) helps in the Southeast corridor; moderates with established public‑lands records (Collins, Murkowski, Capito) are probable yeses; chair-level skeptics (Lee) will likely condition support on amendments narrowing NGO authority.

• House Democrats: Strong support; Natural Resources Ranking Member Jared Huffman and corridor‑state Dems routinely back cooperative trail management. [18]Web search · turn 11 #1
• House Republicans: Leadership and gatekeepers (Chair Bruce Westerman; Federal Lands Chair Tom Tiffany) have prioritized “multiple use” and skepticism of expanding non‑federal managerial vetoes; corridor‑state Republican co‑lead Mike Lawler is a notable exception. Expect a split GOP conference that improves if the Senate sends a narrowed text or a broader parks package. [19]Congress.gov — H.Res. 13 — committee chairs named (incl.

Key Legislators (Pivotal/Swing)

Focus on institutional leverage and corridor‑state incentives.

Leadership Influence and Procedural Dynamics

Where the power sits and how the bill likely moves.

• Senate leadership: Majority Leader John Thune controls floor time; with a 53–47 Senate, most stand‑alone authorizations still need 60. Realistic path is inclusion in a bipartisan ENR package cleared by UC rather than a solo floor push. [10]Office of Sen. John Thune — Thune: First remarks as Senate Majority Leader[11]Legal Information Institute — Cloture (Wex) explainer
• Committee leverage: ENR Chair Mike Lee and National Parks Subcommittee Chair Steve Daines can condition a full‑committee markup on edits. Expect a manager’s amendment softening Sections 4(b)(4) (Designated Operational Partner acceptance/rejection of comprehensive plans), 4(b)(3) (priority lists), and 4(b)(2) (property‑rights redress timelines/costs). [3]Senate ENR Committee — ENR Chair/Ranking announce 119th subcommittee assignments[28]Page view · turn 13 #0
• Executive branch posture: No 119th SAP yet; Interior opposed the prior‑Congress House version (H.R. 9159) over similar NGO authorities and property‑rights process language—signals likely sticking points for Republicans, too. [29]U.S. Department of the Interior — DOI testimony opposing H.R. 9159 (118th)
• House pathway: With Speaker Mike Johnson managing a narrow majority and Westerman/Tiffany holding the pen, the bill is most likely to ride a larger public‑lands/parks omnibus (e.g., a trails/parks package aligned with America250 themes) rather than move alone. [9]AP News — Mike Johnson narrowly reelected Speaker (119th opens)[19]Congress.gov — H.Res. 13 — committee chairs named (incl. Westerman)[4]Wikipedia — House Natural Resources Subcommittee on Federal Lands (119th)
• Package precedent: Recent lands packages (e.g., Dingell Act 92–8 Senate; GAOA 73–25 Senate) demonstrate the model sponsors should aim to replicate. [26]Library of Congress — Dingell Act all‑info (92–8 Senate)[30]Web search · turn 16 #3

Party-Line Expectations and Verified Positions

Public positions and coalition signals to ground the count.

• Sponsors/co-leads: Sen. Kaine (D‑VA), Sen. Tillis (R‑NC); Reps. Beyer (D‑VA) and Lawler (R‑NY). [5]Library of Congress — S.2708 - Appalachian Trail Centennial Act (Congress.gov)[31]Office of Sen. Tim Kaine — Kaine–Tillis press release on introduction (Sept. 4,…
• Committee leadership: ENR chaired by Sen. Mike Lee, Ranking Sen. Martin Heinrich; National Parks Subcommittee chaired by Sen. Steve Daines with Sen. Angus King as Ranking. House Natural Resources chaired by Rep. Bruce Westerman; Federal Lands Subcommittee chaired by Rep. Tom Tiffany.

• Outside support: Appalachian Trail Conservancy leads advocacy; American Hiking Society supported the prior‑Congress version; AT corridor stakeholders (e.g., Maine Trail Center) illustrate GOP corridor backing.

• Hearing held: Senate National Parks Subcommittee heard S. 2708 on December 9, 2025 (SD‑366). [2]Congress.gov — Senate ENR Subcommittee on National Parks hearing (Dec. 9, 2025)
• Corridor-state footprint: A.T. spans 14 states, creating a broad bipartisan constituency that historically votes for omnibus lands deals. [12]National Park Service — NPS article: A.T. spans 14 states / cooperative model[26]Library of Congress — Dingell Act all‑info (92–8 Senate)

Assessment: Likelihood of Passage

• Base case (with amendments): Manager’s amendment narrows NGO authorities (esp. Sec. 4(b)(4), 4(b)(2), and calibrates priority‑list language). ENR reports by voice; measure rides a bipartisan parks/trails package to Senate passage by UC, then to House as part of a larger public‑lands bill. Likelihood: moderate‑to‑high in Senate; moderate in House. Confidence: moderate.

• Unamended stand‑alone path: Low odds. Chair Lee’s gatekeeping plus House Federal Lands skepticism make a solo floor push unlikely; cloture not guaranteed. Likelihood: low. Confidence: moderate. [3]Senate ENR Committee — ENR Chair/Ranking announce 119th subcommittee assignments[11]Legal Information Institute — Cloture (Wex) explainer
• Timing: Earliest realistic window is Q1–Q2 2026 aligned with a broader ENR/House Natural Resources public‑lands package. Hearing box is checked; next step is full‑committee action conditioned on a negotiated text. Confidence: moderate. [1]Congress.gov — Congressional Record Daily Digest: Committee Meetings for Dec. 9…

Amendment Targets That Unlock Votes

Edits most likely to convert committee skeptics and clear House gatekeepers.

1. Replace Sec. 4(b)(4) “accept or reject” comprehensive‑plan authority with a formal consult‑and‑concur process plus written justification if the agency deviates; preserve congressional notification without creating an NGO veto. [28]Page view · turn 13 #0
2. Retune Sec. 4(b)(2) property‑rights redress: keep the ability to file a request with Interior/USDA and the U.S. Attorney, but make timelines advisory and strike fee‑shifting; add a GAO study on trespass/enforcement gaps in trail corridors. [34]Page view · turn 12 #0
3. Clarify Sec. 4(b)(3) priority‑lists as advisory to the Secretary and subordinate to existing statutory land‑acquisition criteria; require public posting and agency rationale when deviating—preserving transparency without binding the agency. [28]Page view · turn 13 #0
