119-HR-3668 DC Insider Whip Count Analysis

Context

H.R. 3668 (Improving Interagency Coordination for Pipeline Reviews Act) would make FERC the sole NEPA lead for interstate gas pipelines/LNG under the Natural Gas Act, set firm interagency timelines, and curb separate state Section 401 certifications by coordinating water-quality terms through FERC. Passed the House on December 12, 2025.

Breakdown — Expected Support/Opposition

Party and caucus alignments reflect recent votes, leadership posture, and committee jurisdiction.

• House pattern: Strongly partisan. GOP near-unanimous support; limited Democratic crossover (7). Motion to recommit failed on party lines. Expect similar polarization to carry into the Senate debate. [2]House Republican Cloakroom — Friday December 12th 2025 - Republican Cloakroom[10]Congress.gov — House Roll Call Vote 333 (MTR on H.R. 3668)
• Senate control and rules: Republicans hold a 53–47 majority, but 60 votes are required to invoke cloture on a contested standalone bill. [3]Wikipedia — 119th United States Congress - Wikipedia[11]Wikipedia — Cloture — Senate threshold overview
• Committee signal: Senate ENR (Chair Mike Lee; RM Heinrich) and EPW (Chair Shelley Moore Capito; RM Whitehouse) are friendly to faster permitting but diverge on the scope of Section 401 reform. Expect EPW Democrats to resist 401 curbs.

• Leadership/industry vs. environmental blocs: API and allied coalitions are publicly pushing for passage; LCV and green groups are mobilized against H.R. 3668 as part of an anti‑environmental slate.

• Senate strategy landscape: Upper chamber is already crafting a broader, more bipartisan permitting package (transmission/NEPA focus). That vehicle is the likeliest home for any modified H.R. 3668 language. [1]Reuters — US House passes bill to fast-track natural gas pipeline permitting

Key Legislators — Likely Pivots

These senators have leverage over text and floor outcome; cited positions indicate potential openness to permitting changes but sensitivity to water/NEPA scope.

• Mike Lee (R‑UT), Chair, Senate ENR — controls primary jurisdiction and markup strategy; committee notice confirms chairmanship. Expect to favor FERC‑centric streamlining. [12]U.S. Senate Energy & Natural Resources Committee — Heinrich, Lee announce ENR s…
• Shelley Moore Capito (R‑WV), Chair, Senate EPW — long‑running push for Section 401 guardrails; seeking bipartisan deal framing. Likely to defend core 401 limits but may negotiate timelines/process over outright displacement. [17]Web search · turn 3 #2[4]U.S. Senate EPW Committee/Office of Sen. Capito — Chairman Capito on Permitting…
• Angus King (I‑ME) — vocal for “timely and predictable” permitting with standards intact; possible yes if 401 language is narrowed to timelines/coordination. [18]Office of Sen. Angus King — Sen. Angus King statement on failed permitting vote
• John Hickenlooper (D‑CO) — backs bipartisan permitting (BIG WIRES/SPEED concepts). Could support a package if transmission/clean‑energy pieces balance fossil provisions; standalone 401 curbs are harder. [19]Office of Sen. John Hickenlooper — Hickenlooper: Bipartisan permitting package…
• Lisa Murkowski (R‑AK) and Susan Collins (R‑ME) — institutional moderates; supportive of permitting but protective of state roles. They are potential internal negotiators on 401 language. (Inference based on their profiles; no public 3668 statement yet.)
• Martin Heinrich (D‑NM), Senate ENR Ranking Member — advancing methane safety and climate‑aligned gas standards; signals Democratic negotiating lane focused on environmental safeguards. [20]Web search · turn 13 #0
• Dick Durbin (D‑IL)/Tammy Duckworth (D‑IL) — introducing bills to expand FERC climate/EJ review of pipelines; strong indicators of caucus resistance to weakening reviews, shaping the left flank’s red lines. [21]Office of Sen. Dick Durbin — Durbin/Duckworth press release on FERC GHG & EJ Po…

Leadership Influence and Procedural Dynamics

Outcome will be set by leadership timing, committee drafting, and whether this rides a broader vehicle.

• Senate floor control: Majority Leader John Thune sets timing; with 53 seats, leadership still needs 7+ Democrats/Independents for cloture on a standalone. More plausible path is to hitch to a bipartisan ENR/EPW package. [22]Office of Sen. John Thune — Thune delivers first remarks as Senate Majority Lea…[3]Wikipedia — 119th United States Congress - Wikipedia[11]Wikipedia — Cloture — Senate threshold overview
• Committee leverage: ENR will write the core; EPW’s jurisdiction over Section 401 gives it de facto veto over water language. Chairs Lee and Capito have both prioritized permitting this Congress. [12]U.S. Senate Energy & Natural Resources Committee — Heinrich, Lee announce ENR s…[14]U.S. Senate EPW Committee — EPW majority notice — subcommittee assignments (119…
• House posture: E&C GOP leadership is touting H.R. 3668 as part of a cost/reliability push, building negotiating chips for conference with the Senate. [23]House Energy & Commerce Committee (Republicans) — House E&C Republicans tout pa…
• Executive branch winds at the back: EPA leadership has already signaled a narrower interpretation of Section 401 this year, aligning with the pro‑streamlining narrative (even as the statute remains unchanged). That reduces political risk for modest 401 guardrails in the Senate. [24]U.S. EPA — EPA memo on aligning Section 401 practice
• Calendar: With year‑end floor time exhausted, realistic window is early 2026, when ENR/EPW permitting vehicles return; stand‑alone Senate floor time for 3668 is unlikely absent a UC agreement. [1]Reuters — US House passes bill to fast-track natural gas pipeline permitting

Assessment — Likelihood of Passage

Bottom line from a whip and procedure lens.

• Standalone Senate passage of H.R. 3668 as written: low (≈25%). GOP unity is likely, but 60 votes are not there given Section 401 displacement and Democratic counter‑bills strengthening FERC environmental review. [9]League of Conservation Voters — LCV statement opposing H.R. 3668 and related bi…[21]Office of Sen. Dick Durbin — Durbin/Duckworth press release on FERC GHG & EJ Po…
• Inclusion of narrowed H.R. 3668 elements (FERC lead‑agency clarity, schedules, transparency) in a broader bipartisan permitting package: moderate (≈55%). Senate effort already underway emphasizes transmission/NEPA; a calibrated 401 timeline/coordination fix could make the cut. [1]Reuters — US House passes bill to fast-track natural gas pipeline permitting
• Most probable outcome: Senate negotiates a permit package, trims 401 language to timelines/standards rather than categorical certification displacement, keeps FERC coordination and 90‑day post‑NEPA deadlines, then sends a package to conference where House accepts most of the Senate 401 edits.
