The state of New Mexico has fined federal energy regulators and private contractors for actions that led to a serious radiation leak in the nation’s only repository for nuclear waste, which is now closed for the foreseeable future.
In February, a drum of radioactive waste ruptured half a mile underground at the Waste Isolation Pilot Plant (WIPP) near Carlsbad. The leak caused temperatures to soar to 1600 degrees Fahrenheit, threatening to set off a chain reaction of ruptures in other drums.
The problem was allegedly caused when the contractor hired by the U.S. Department of Energy (DOE) mixed organic kitty litter with acid neutralizers as part of the storage of nuclear waste. It has been speculated that the use of the kitty litter resulted from a typographical error that occurred in 2012 during the process of revising a government manual on the proper handling of nuclear waste. Waste handlers had previously been instructed to stop using the litter.
The combination, according to New Mexico officials, “could lead to or cause the generation of extreme heat, pressure, fire, explosions or violent reactions; or a threat to human health or the environment.”
Citing 37 violations of hazardous waste permits, the state Environment Department has thus far levied $54 million in penalties against the DOE and its contractor—$36.6 million to the Los Alamos National Laboratory (the original source of the waste) and $17.7 million to WIPP. It is the largest amount of penalties ever charged to a federal agency by the state. The figure may grow as the investigation continues.
“New Mexico is proud of our national labs and cutting-edge scientific facilities, and we have important rules in place to protect those facilities, the people who work there, and all New Mexicans,” Governor Susana Martinez said in a statement. “The health and safety of New Mexicans will always be our priority and we have to hold federal agencies accountable for safe operations in the state of New Mexico.”
The leak exposed at least 20 workers to radiation.
