As drought threat looms, Los Alamos National Lab works to reduce its wildfire risk

As New Mexico water and fire managers prepare for increased drought and wildfire danger this summer, Los Alamos National Laboratory officials say the lab has taken steps to mitigate those threats on its campus.
LANL provided a media tour mid-week to highlight those steps, but did not allow outside photography or recording.
'We're very proud of our preparedness efforts for wildfire,' said Deputy Laboratory Director of Operations Mark Davis from the floor of the Emergency Operations Center, as videos of the 2022 Cerro Pelado fire played across six screens on the wall. 'We want to show our efforts to communicate how our mitigation efforts will protect the lab, workforce, community and environment.'
The state has identified the towns of Los Alamos and White Rock as high risk areas for wildfire threats, including LANL, which spans 36 square miles of mesas and canyons. The lab and surrounding town have been evacuated twice in the past 30 years due to fires. That included evacuations for two weeks during the Cerro Grande Fire in 2000, which burned 43,000 acres total, including 45 lab buildings and 7,500 acres of LANL property. Los Alamos evacuated for another 10 days during the 2011 Las Conchas fire, which burned more than 156,000 acres, though only one acre on the lab's property.
In 2022, during the same time the Hermit's Peak-Calf Canyon fires raged, the Cerro Pelado fire, also caused by a controlled burn, sparked up and ultimately burned 45,000 acres, requiring the lab to move to remote work in preparation for an evacuation.
In 2022, at the request of the Biden Administration, LANL released its Climate Change Vulnerability Assessment and Resilience Plan, which showed that increased wildfire presented the highest risks to equipment, electricity systems, onsite radioactive waste processing, buildings, water systems and communications systems.
Critics say climate threats to the laboratory are compounding. LANL's proposed thinning is 'a slow job, but certainly necessary,' said Greg Mello, the executive director of nuclear nonproliferation nonprofit Los Alamos Study Group. But he said the hazards with climate change are stacking up.
'We just wish that the laboratory wasn't straining against every single environmental constraint that there is on that plateau,' Mello said. 'The laboratory is too big and trying to do too much in a place that was never appropriate for a laboratory of the present scale, let alone the additional laboratory facilities and staff that they envision.'
The approximately 18,000 people employed at LANL work mostly in science and engineering, from modeling infectious diseases to increasing the U.S. nuclear weapons stockpile.
'Our missions are vital and critical to national security and they cannot fail,' Davis said.
The Jemez wilderness bears scars from the Cerro Grande and Las Conchas fires. Large bald patches with skinny charred remains of the ponderosa pines stand among scrub oak brush replacing the once-forested area.
Recent scattered rainstorms offered a small reprieve, but the area remains in Stage 1 fire restrictions — an elevated threat level that restricts all campfires or outdoor burning.
Laboratory facilities are interspersed on the top of mesas to higher elevation ponderosa pine forests, separated by canyons and arroyos filled with brush. The lab is bordered by federally managed forests; San Ildefonso and Jemez Pueblos; and Santa Fe and Los Alamos County land.
The patchwork of agencies has complicated firefighting and mitigation efforts in the past, said Jeff Dare, who leads the Emergency Operations Center, but Cerro Pelado offered a framework for more cooperation with members of county government and liaisons for surrounding federal agencies and tribal governments.
The lab is part of the Master Cooperative Wildland Fire Response Agreement, which allocates additional resources such as helicopters and personnel to fight any wildfire that does appear, Dare said, adding: 'It protects the laboratory before it can get here.'
The more recent focus has been trimming back the areas around lab buildings, roads and utility lines, said Richard Nieto, LANL's wildland fire program manager. Trimming has occurred on an estimated 12% to 15% of lab property.
'Hope is not a strategy,' Nieto said, adding that the area needs to better adapt to fires when they happen. 'This area was meant to burn; it's what we have to deal with, ecologically.'
But overgrowth is a challenge. Much of the higher-elevation ponderosa forests sport 400 to 1,300 trees per acre, rather than the healthier 50 to 150 trees per acre, he said. Habitats for two endangered species and archeological sites also require consideration.
Beyond trimming, the lab is working on developing plans for prescribed burns, but will take another three to five years to realize, he said.
On the other side of lab property, fences looped with concertina wire and sporting signs warning of radiological hazards contain Area G.
Vaguely merengue- shaped white tents — coated in fireproof material — stand amid the juniper and piñon scrub. Inside, under crisscrossed steel frames, stacked white containers on metal pallets contain legacy waste from the lab's work in the nuclear program.
The facilities are geared to reducing fire concerns, said Gail Helm, the facility operations director for N3B, which is contracted to manage the 10-year $2 billion dollar cleanup of Cold War Era legacy waste. The tents include fire detection and suppression. Concrete barricades surround them to prevent vehicle accidents and potential fires. Under the Stage 1 fire restrictions, a water truck remains onsite at all times.
To the west of Area G lies Technical Area 53, where the lab logs and stores new transuranic nuclear waste — such as gloves contaminated with plutonium — produced at the new plutonium pit production site. The waste is eventually disposed off-site at the Waste Isolation Pilot Project outside of Carlsbad.
Thomas Vigil, the deputy group leader at the Chemical and Waste Facilities said LANL is doing 'its due diligence' to follow every protocol to keep the public and workers safe.
'This is my state, this is where we live,' he said. 'I live just down the road, and it's important to me.'
