A top nuclear laboratory in the United States is at risk from wildfires because some mitigation measures have been ignored in recent years, an audit found.
The Department of Energy’s (DOE) inspector general said the Los Alamos National Laboratory (LANL) in New Mexico is prone to “future large, high-intensity wildfires that could threaten to seriously interrupt mission work,” as a large fire did in 2000.
The Cerro Grande Fire that year burned over 7,500 acres of department land, damaging or destroying over 100 structures and ruining a variety of lab projects and scientific records and forcing the lab to close for 15 days.
Another wildfire in 2011, the Las Conchas Fire, burned an acre of department land and its intensity and proximity to the lab forced it to close for nine days.
In light of the fires, the inspector general undertook an audit to see whether its Los Alamos office and lab contractors were taking steps to try to avoid potential fire-related closures and losses.
The review found mitigation measures like tree thinning were not always performed, “increasing the potential for a devastating wildland fire to spread.” Other highlighted concerns included a lack of maintaining fire roads and a lack of documentation of what measures have been completed.
“Without documenting planning and preparedness activities, there was no assurance that all prevention and mitigation options were considered and that the site was fully prepared for wildland fire events,” the inspector general’s office said.
The lab is located about 35 miles northwest of Santa Fe in rugged northern New Mexico. Promoting and protecting national security through work on nuclear weapons, lab workers research renewable energy, nanotechnology, and other subjects. The lab employs some 12,000 people and includes approximately 2,000 structures, including 13 nuclear facilities, strewn across 36 square miles.
The watchdog group Nuclear Watch New Mexico said the audit showed the need for a new site-wide environmental impact statement.
“The lab and DOE have so far blocked a new site-wide environmental impact statement which, as the past has shown, is actually in their own best interests. We believe LANL and DOE have a legal requirement to prepare a new one and NukeWatch will be pursuing that,” Jay Coghlan, director of the group, said in a statement.
The lab and the department didn’t reply to requests for comment. A lab spokesperson told The Associated Press that since the audit was performed in 2018 and 2019, the lab has been aggressively completing wildfire management tasks.
“We continue to review our wildfire and forest health plans and have already implemented most of the recommendations the Department of Energy offered to improve our efforts to protect the public, the environment and the laboratory,” he said.
Managers wrote to the inspector general to say they concurred with the audit’s recommendations and that many of the recommended actions, such as conducting a site-wide wildfire risk assessment, were already planned or started.
“Because the audit focused on prior plans, most of the salient issues in the report had already been identified and captured,” William Bookless, the acting under secretary for Nuclear Security and administrator at the National Nuclear Security Administration, wrote to Inspector General Teri Donaldson last month.
“We have prioritized and implemented actions to protect employees, the public, and the site’s critical infrastructure from the risks of wildland fire,” he added.
