The Senate Environment and Public Works Committee considered the nomination of Dr. Allison Macfarlane to serve a full term as Nuclear Regulatory Commission Chairman on May 23. While most of the committee praised her work at the commission, Senators John Barrasso (R-WY), James Inhofe (R-OK), and Jeff Sessions (R-AL) expressed concerns about some of her work, including her vote on a filtered vents rule. Macfarlane’s current term expires June 30, and a committee vote is expected as early as next week.
