119 · S 1926 Reducing Waste in National Parks Act

Overall likelihood this Congress (as introduced)
8%
0%25%50%75%100%
GOP control of both chambers, ENR Chair Lee’s gatekeeping power, and a Trump DOI that rescinded the 2022 plastics phase‑out put S.1926 on a very cold track; a Dec. 9 National Parks Subcommittee hearing occurred, but the bill is unlikely to see markup or clear a 60‑vote Senate, with only a slim chance of watered‑down provisions hitching a ride on a broader parks package.

Bill and Context (one‑paragraph brief)

S.1926 (Merkley) directs the National Park Service to reduce and, where feasible, eliminate sales or distribution of disposable plastic products in park units, with program design factors for refill stations, concession contracts, visitor education, and biennial evaluations; it was referred to Senate Energy & Natural Resources (ENR) and noticed for a Dec. 9, 2025 National Parks Subcommittee hearing.

Rationale: Republicans control both chambers; ENR is chaired by Sen. Mike Lee (R‑UT), and House Natural Resources is chaired by Rep. Bruce Westerman (R‑AR), aligning committee gatekeepers against a plastics‑restriction mandate. The administration has also reversed the 2022 DOI plastics phase‑out, signaling policy opposition from the executive. Finally, absent reconciliation, the Senate’s 60‑vote cloture threshold is a hard ceiling for a partisan-tilted environmental policy.

Public opinion modestly helps proponents (bipartisan voter support for reducing single‑use plastics), but it does not overcome institutional control and floor math in this Congress. [8]Ipsos — Ipsos/Oceana poll: Three in four Americans support national policies to…

Obstacles

  • Committee gatekeeping: ENR Chair Lee can deny or reshape markup; the National Parks Subcommittee is chaired by Sen. Steve Daines (R‑MT), who set the Dec. 9 docket and is focused on a broader parks agenda. [2]U.S. Senate ENR Committee — Chairman — U.S. Senate Committee on Energy and Natu…[9]U.S. Senate ENR Committee — ENR Subcommittee on National Parks — Roster (Chair…[4]Congress.gov — Committee Schedule for 12/09/2025 — Includes S.1926 on National…
  • Executive branch posture: DOI rescinded Secretary’s Order 3407 (the 2022 plastics phase‑out), and the White House publicly moved to restore/encourage plastics use in federal settings, implying an OMB/SAP headwind and potential veto threat. [3]U.S. Department of the Interior — RESCINDED: Secretary’s Order 3407 — Departmen…[10]The White House — Fact Sheet: President Donald J. Trump Ends the Procurement an…
  • Senate floor math: With the filibuster intact, 60 votes are required for cloture on most legislation; this policy change is not germane to reconciliation and would be vulnerable to Byrd Rule points of order if attempted there. [7]Congressional Research Service via Congress.gov — Filibusters and Cloture in th…[11]Congressional Research Service via Congress.gov — The Senate’s Byrd Rule: Frequ…
  • House back‑end: If the bill reached the House, Natural Resources Chair Westerman controls the gate; the majority’s priorities make restrictive plastics mandates unlikely to advance. [6]Congress.gov — Text — H.Res.13 (119th): Committee Chairs, including Natural Res…

Short‑Term Consequences

  • If it advances to markup: Expect narrowing amendments (e.g., voluntary visitor‑education and refill‑station encouragement; removal of explicit sales elimination), aligning with DOI policy and concessioner concerns; any report would signal intent to fold pieces into a larger parks package. [3]U.S. Department of the Interior — RESCINDED: Secretary’s Order 3407 — Departmen…
  • If it stalls after hearing (most likely): Status quo persists under DOI rescission; sponsors gain messaging against the administration’s plastics stance, buoyed by polling showing broad voter concern about single‑use plastics.

Long‑Term Consequences

  • Precedent path: NPS plastics policy has swung by administration (2011 bottle sales guidance; 2017 reversal; 2022 DOI phase‑out; 2025 rescission). Absent statute, future swings likely; codification would stabilize policy but is improbable this Congress.

  • Packaging into an omnibus: Select, de‑risked provisions (signage, refill‑station pilots, reporting) could hitch a ride on a broader bipartisan parks/lands bill before America250; Daines flagged ongoing work on a larger parks agenda. [15]Office of Sen. Steve Daines — Daines Chairs Senate National Parks Subcommittee…
  • Electoral signaling: Even without enactment, Democrats frame plastics reduction around popular majorities in polling; Republicans frame mandates as operational/cost burdens, consistent with current DOI posture—reinforcing coalition narratives into 2026.
