The last of three Trump administration nominees to the Nuclear Regulatory Commission is headed for a Senate floor vote following approval Wednesday by the Senate Environment and Public Works Committee.

The panel backed Commissioner Jeff Baran’s reappointment on a voice vote alongside two nominees for assistant administrator spots at the Environmental Protection Agency and the nominee to lead the Federal Highway Administration. Separate roll-call votes were held for two other EPA assistant administrator nominees, Michael Dourson and William Wehrum, who several Democrats excoriated but could not stop from proceeding toward confirmation.

None of the committee members discussed Baran at length during the business meeting. Panel Chairman John Barrasso (R-Wy.) encouraged his fellow senators to vote to confirm all other nominees being considered Wednesday, but notably did not do the same when he raised Baran’s nomination – another example of his clear reservations on the matter.

During the Oct. 4 confirmation hearing for Baran and the other nominees, Barrasso pressed the commissioner regarding his perceived opposition to the Yucca Mountain nuclear waste repository in Nevada. He called Baran’s nomination a “big ask” at the time.

Baran has served on the committee since 2014. He is now awaiting Senate confirmation for a full five-year term ending June 30, 2023.

EPW Committee Ranking Member Tom Carper (D-Del..) has openly advocated a Senate vote on Baran concurrent with fellow NRC nominees Annie Caputo and David Wright, who secured the panel’s approval earlier this year to fill vacant spots on the commission. Republican lawmakers appear to have accepted keeping Democrat Baran on the commission as the means for ensuring a smooth confirmation for Republicans Caputo and Wright.

Senate Majority Leader Mitch McConnell (R-Ky.) would schedule the vote. His staff on Wednesday did not provide a projected timeline for the nominee vote introductions.
