Kenney’s latest Washington trip renews pressure on DOE over Los Alamos waste

Environment secretary also met with federal officials to push for changes to WIPP’s permit for storing legacy nuclear waste

James Kenney, Gov. Michelle Lujan Grisham’s environment secretary, flew to the nation’s capital for a July 7 meeting with top U.S. Department of Energy officials.

It was Kenney’s latest attempt to remind D.C. that radioactive and hazardous waste has been festering in Los Alamos since the 1940s Manhattan Project.

It was one of roughly six trips Kenney has made to Washington during President Donald Trump’s second term, he said in a wide-ranging interview before his latest visit.

Kenney met last week with Timothy Walsh, assistant secretary for the Office of Environmental Management in the U.S. Department of Energy.

The two discussed New Mexico’s April request to revise DOE’s 10-year permit to store radioactive debris in the underground caverns of the Waste Isolation Pilot Plant, or WIPP, in Carlsbad.

In a 2023 settlement with New Mexico, the DOE agreed to prioritize shipments of radioactive waste from LANL over out-of-state U.S. nuclear facilities.

“The Department of Energy’s Carlsbad office is favoring cleanup everywhere else in the country except New Mexico’s backyard,” Kenney said.

A spokesperson for Kenney’s agency said it received 859 public comments on the permit modification. Roughly half supported New Mexico’s revisions and the other half opposed them.

DOE runs the WIPP site with Salado Isolation Mining Contractors, or SIMCO. WIPP disposes of waste materials from sites across the U.S. Kenney expects a resolution on the permit by this fall.

Kenney said Walsh “seems very level-headed and very interested in solving problems.”

“If everybody’s rowing in the same direction at the same time, between our Congressional delegation, the Department of Energy, the state of New Mexico, the community, this actually could be a good moment,” he said.

Before Congress is an appropriations package that would slash the office’s budget and hike funding for accelerated production of plutonium pits, the inside nuclear weapons at LANL. The package passed a House Appropriations Committee. Kenney visited the Hill in April to meet with U.S. lawmakers and staff to request more cleanup funds.

But Kenney has found that not everyone, in New Mexico and D.C., is rowing in his direction.

“They want it to be over 50% of the shipments,” Jack Voltato, a pharmacist and GOP politician who has held several local offices in Carlsbad, said of LANL waste. “And there’s no way they can ever get to that number. They don’t have the capacity. They don’t have the characterization teams. They don’t have the real estate basically.”

‘Difficult tradeoffs’

In late May, U.S. Rep. Chuck Fleischmann, a Tennessee Republican, introduced the bill. A on the bill follows Trump’s prior recommendation that the DOE cut cleanup spending while hiking funds for new nuclear weapons.

The committee report justified cuts to the Office of Environmental Management, saying the office has $507 million in unspent funds.

“Given resource constraints, the Committee must make difficult tradeoffs to prioritize the greatest needs in a fiscally responsible manner,” the report said, adding that it expects DOE to make progress on nuclear waste cleanup with $275 million of those unspent funds.

Among other criticisms of the bill, Democratic lawmakers said cuts to the Office of Environmental Management budget by $863 million, or 10%, would leave “communities vulnerable to radioactive waste leftover from our nation’s atomic weapons program.”

Republicans on the House Appropriations Committee took a different posture on defense spending, saying in their report that NNSA’s national defense programs should be the DOE’s “top priority” amid rising global threats.

It recommended $22 billion for those programs. That includes money to support the production of 80 plutonium pits annually by 2030 at LANL and the Savannah River Site in South Carolina. The bill specifically allocates $2 billion for pit production at LANL — $755 million over last year’s budget.

A public comment period on NNSA’s proposal to expand plutonium production at LANL and the Savannah River Site closes July 16.

Asked about cleanup funds, U.S. Sen. Martin Heinrich, a member of the Senate’s Appropriations and Intelligence committees, told the Journal in a statement that the “federal government has a responsibility to support the communities that safely manage our nation’s nuclear materials and waste, including maintaining the roads used to transport that waste.”

Heinrich referenced Kenney’s longstanding request for money to improve the roads in Carlsbad where heavy trucks carry the waste.

Chromium plume

Thom Mason, director of LANL, was asked during a June town hall how long it would take to remove the legacy waste.

“I probably shouldn’t talk too directly about the legacy waste,” he said, pointing to the DOE’s Environmental Management Office as responsible for the cleanup.

He faced another question about a plume of hexavalent chromium — a dangerous pollutant that is encroaching on San Ildefonso Pueblo.

“Some of the things that are concerns of the community (like) the chromium plume — those are things that we’re not responsible for,” Mason said, describing the relationships between different agencies and contractors.

“What we are responsible for is the waste generated as a part of our current operations,” Mason said, adding later that the lab does not cut corners on safety.

Kenney noted hexavalent chromium is not in San Ildefonso’s drinking water today. Roughly one mile long and half as wide, the plume is beneath Mortandad Canyon and at the edge of the Sandia Canyon at LANL, according to DOE, which says there is “no immediate threat to human health or the environment.”

Republicans control the Senate and House in Washington. Kenney said members from both parties are on the same page in funding cleanup alongside weapons programs, even if Republicans have not been as vocal about it.

“When you dump hexavalent chromium in the 1950s, and it is still threatening people’s drinking water in 2026, you have to ask yourself what meaningful effort the Department of Energy has achieved to mitigate that risk,” Kenney said.
