Nominations of Ho Nieh (NRC) and Douglas Troutman (EPA Chemical Safety)

Purpose

The Senate Environment and Public Works Committee held this hearing to consider two nominations: Ho Nieh, nominated to fill an unexpired term on the Nuclear Regulatory Commission, and Douglas Troutman, nominated to be Assistant Administrator for the EPA's Office of Chemical Safety and Pollution Prevention. Members questioned the nominees on NRC independence amid recent staff departures and the unprecedented removal of a sitting commissioner, and on delays and outcomes in EPA's chemical review process under TSCA. Begins at0:14:53

Who spoke

Chair Shelley Moore Capito (R-WV)0:14:53: Introduced both nominees, argued strong unified NRC leadership is needed to build nuclear "safely and quickly"0:15:24, and said EPA's chemical review system "assumes the worst of every product" while leaving legacy chemicals untouched0:17:27; later defended the administration's review pace against Sen. Markey1:42:24.

Sen. Sheldon Whitehouse (D-RI), Ranking Member0:19:25: Warned Nieh the NRC has been "gutted" of staff over nine months and cited the first-ever firing of a commissioner without cause0:20:47; called Troutman a career oil, gas and chemical industry lobbyist who holds stock in Dow and Procter & Gamble0:23:11; pressed Nieh on four specific dangers to NRC independence0:43:50 and asked if he'd resist political pressure "even if it gets you fired"0:47:34.

Sen. Katie Britt (R-AL)0:24:21: Introduced Ho Nieh as an Alabama native, described his 20+ years at NRC including work bringing Vogtle Units 3 and 4 online0:26:53, and urged the committee to support his nomination0:27:16.

Ho Nieh, NRC nominee0:28:35: Said soaring AI/data center electricity demand makes nuclear increasingly important0:29:29; described leading a 2018–2021 NRC "culture change" toward a more "enabling" regulator0:30:33; committed to the NRC's independent safety mission "100%"0:46:58 and confirmed he'd watch for "fossil fuel moles" infiltrating the agency0:48:56; would not speculate on 2030 reactor-licensing timelines but insisted safety comes first1:18:54.

Douglas Troutman, EPA nominee0:33:41: Said timeliness and outcomes are both problems in chemical review and cited new resources coming to the chemical safety office0:39:10; repeatedly declined to directly affirm that some communities face disproportionate chemical exposure risk, instead citing statutory review of a pending rule0:57:480:59:40; said "nothing will change" in the rigor of pre-manufacture notice reviews for AI-related chemicals1:37:211:40:12.

Sen. John Curtis (R-UT)0:49:18: Asked Nieh how states like Utah can be engaged in expediting nuclear siting and pilot programs0:49:49; noted the prior administration approved 0% of chemical reviews within statutory deadlines0:52:46.

Sen. Alex Padilla (D-CA)0:54:26: Called the firing of former Commissioner Chris Hansen "illegal" and said it taints the nomination process0:54:49; got Nieh to commit that DOGE/DOE staffers will not dictate NRC policy0:55:43 and that NRC has unique reactor-licensing expertise DOE lacks0:56:10; pressed Troutman on disproportionate chemical risk to nearby communities without a direct answer0:59:05.

Sen. Pete Ricketts (R-NE)1:00:00: Asked whether EPA has consistently followed sound science on pesticide approvals, citing Biden-era overestimates of foreign pesticide use1:00:30; questioned EPA's use of maximum-application assumptions in risk modeling1:02:46.

Sen. Jeff Merkley (D-OR)1:05:35: Criticized Troutman for evading Padilla's "simple" question on disproportionate community risk1:05:58; cited a MAHA report finding brain tissue microplastic concentrations rose 50% from 2016–20241:06:59 and pressed for PFAS consumer labeling1:11:20.

Sen. Lisa Blunt Rochester (D-DE)1:12:36: Criticized holding routine hearings during the government shutdown and urged Republicans to negotiate reopening1:13:29.

Sen. Mark Kelly (D-AZ)1:14:51: Raised concerns about NRC modeling itself on the industry-funded, non-public Institute of Nuclear Power Operations1:15:45; questioned whether the administration's goal of 10 new reactors by 2030 and 3 SMRs by next July is achievable without sidelining safety or public participation1:18:031:19:04.

Sen. Cynthia Lummis (R-WY)1:20:35: Asked how Nieh would keep early movers like Wyoming-based TerraPower from being disadvantaged by shifting regulatory frameworks1:22:02; asked Troutman how he'd balance access to chemicals needed for mining/critical minerals with health protections1:26:15.

Sen. Angela Alsobrooks (D-MD)1:28:03: Noted the NRC furloughed 1,837 employees on October 1, leaving 820 working without pay1:29:09; asked Nieh to commit to hiring only technically qualified senior NRC staff1:30:53.

Sen. Ed Markey (D-MA)1:32:39: Asked whether it's appropriate for White House political appointees to have final review over NRC safety decisions1:33:03; said NRC job postings now include an essay question on favorite Trump executive orders1:35:11; challenged Troutman over EPA Administrator Zeldin's statement that EPA "wants to get out of the way" on reviewing AI-data-center chemicals1:37:04.

Key moments

Whitehouse said this is the first time in NRC history a commissioner was fired without cause, calling it evidence of political pressure on the agency0:20:47.

Whitehouse laid out four specific "dangers" to NRC independence: White House political influence, DOE infiltration, staff collapse, and fossil-fuel-industry "moles" being placed inside the agency0:43:50; Nieh committed to being "100%" independent even under pressure0:46:58 but would not speculate on the mole concern beyond saying he'd "keep an eye out"0:48:560:49:05.

Alsobrooks stated the NRC furloughed 1,837 employees on October 1 amid the shutdown, leaving only 820 working without pay, and cited 11 senior managers who have departed since July, some pushed out by DOGE detailees1:29:091:29:34.

Padilla and Merkley both pressed Troutman on whether communities near chemical facilities face disproportionate health risk; Troutman repeatedly declined to give a direct yes/no, citing statutory process, prompting Merkley to say "just say yes"0:57:480:59:051:05:58.

Markey confronted Troutman with EPA Administrator Lee Zeldin's statement that "the Trump EPA wants to get out of the way" on reviewing chemicals for AI data centers, asking what legal provision authorizes that; Troutman said "nothing will change" in the review's rigor1:37:041:37:21.

Kelly noted the administration's goal of 10 new reactors by 2030 is "nearly as many as have been done in the past 25 years" and asked if it can be done safely without sidelining public participation1:18:03; Nieh declined to endorse or dispute the timeline, saying safety must come first1:18:54.

Markey said NRC job applications now include an essay question asking candidates about their favorite Trump executive orders, calling it a "loyalty test" contrary to civil service and independent-agency norms1:35:11.

Capito and Markey sparred directly over responsibility for chemical review delays, with Capito arguing the prior administration "didn't do anything" and let new, safer chemistries sit unapproved1:42:53, while Markey said the current administration is prioritizing AI data centers over chemical safety review1:41:12.

Curtis noted the prior administration had a 0% record of completing chemical reviews within statutory deadlines0:52:46.

Nieh confirmed he would treat nuclear fuel-cycle licensing (conversion and enrichment) with the same priority as reactor licensing if confirmed1:25:051:25:35.
