CARLSBAD, NM (KWES) - The WIPP Emergency Operations Center has been deactivated.
A calculation error caused a false positive at a surface air monitoring station.
Through radiological surveys, Radiological Control Technicians have determined that no contamination occurred.
The WIPP plant has been closed since last February after a truck caught fire and a radiation leak.
The transuranic waste that was being stored came from the Los Alamos National Laboratory.
Investigators say the leak happened after a bad reaction from using organic cat litter to store it.
