The nation’s only underground nuclear waste dump is back in operation again. The Waste Isolation Pilot Plant near Carlsbad stored low level nuclear waste deep in the earth Wednesday for the first time since the facility was closed following a fire and a radiation leak in early 2014.

The New Mexico Environment Department enforces hazardous waste regulations at WIPP. Secretary Butch Tongate says they’ve reviewed procedures, equipment, safety protocols and permit compliance at the facility.
