In a December public meeting, the field office’s manager indicated approval from the Environment Department likely wasn’t needed to defer the study and cleanup of Area C. According to the compliance decree, “NMED approval is not required” in several cases to change the status of an area to deferred, as long as the Department of Energy complied with other requirements.
Environment Department spokesperson Drew Goretzka wrote in an email to The New Mexican a site can be deferred in one of four cases, including if it is involved in active operations and if the amount of time needed for deferment is assessed.
The department doesn’t agree those requirements have been met, Goretzka wrote, “resulting in a breach of the Consent Order.”

The U.S. Department of Energy has put cleanup of a hazardous waste disposal site at Los Alamos National Laboratory on hold, a decision that seems to have drawn the ire of the New Mexico Environment Department.
The state last year was planning to hold a public hearing in early 2026 on how to handle legacy waste left behind at Material Disposal Area C, according to a letter from an official in the Hazardous Waste Bureau.
The Department of Energy, however, had already made up its mind: Any corrective actions at the site would have to wait due to ramped-up operations near Area C. The public hearing is now on hold until the conflict over the deferment of corrective actions is settled, according to an Environment Department spokesperson.
The 11-acre waste site, in use from 1948 to 1974, is located within Technical Area 50 along Pajarito Road. Its six disposal pits were used for various types of waste, including radioactive materials and heavy metals.
