Anne Marie White resigns, Capitol Building

Major personnel changes at some of the highest levels of the U.S. Department of Energy and its semiautonomous National Nuclear Security Administration are under way, according to a department announcement reviewed by the Aiken Standard on Friday.

Anne Marie White – the woman atop the DOE Office of Environmental Management, the Savannah River Site landlord – has submitted her resignation, according to the announcement, which is signed off with the names of Secretary of Energy Rick Perry and the Deputy Secretary of Energy Dan Brouillette.

White's resignation is effective June 14. The assistant secretary for environmental management was confirmed in March 2018, bringing her total time at the helm to just over one year.

No reason for her leave was given in the memo.

"Anne's service to the Department of Energy and to this nation are greatly appreciated," the personnel announcement reads. "Please join us in wishing her the best in her future endeavors."

Environmental Management, established in 1989, is charged with cleaning up the nation's legacy from the Cold War and other government-sponsored energy research. At the Savannah River Site, Environmental Management's tasks include processing millions of gallons of radioactive liquid waste.

White toured SRS for the first time last year. She visited the Defense Waste Processing Facility – a behemoth waste-glassification plant – and the Savannah River National Laboratory, among other venues.

"The work being done at Savannah River is important work, good work," White wrote in field notes, which were posted to the DOE's website.

Mark Gilbertson, Environmental Management's No. 2, is also switching gears. Gilbertson – who recently came to Augusta and spoke to a nationwide nuclear panel – will become the director of the DOE's National Laboratory Operations Board, according to the memo.

The board works to strengthen DOE's national labs and their shared relationships.

Todd Shrader, the manager of Environmental Management's Waste Isolation Pilot Plant Carlsbad Field Office, will replace Gilbertson as the principal deputy assistant secretary, the memo states. WIPP is in New Mexico, south of Roswell.

William "Ike" White, the NNSA chief of staff, will now serve as a senior adviser to DOE Under Secretary for Science Paul Dabbar. Dabbar oversees environmental- and legacy-management missions, among other things.

The NNSA is in charge of the nation's nuclear complex and related nonproliferation. The NNSA operates at SRS.

Meantime, longtime senior physicist William Bookless was sworn in as the NNSA's second in command – as its principal deputy administrator – on Friday.

Organization charts for Environmental Management and NNSA do not reflect the announced changes as of Friday evening.
