The site of last year's deadly coal mine explosion in West Virginia may be abandoned and sealed-off, according to the Mine Safety and Health Administration (MSHA).
29 coal miners died at Massey Energy's Upper Big Branch (UBB) mine a year ago in the nation's worst mine disaster in four decades.
"Massey Energy has indicated it wants to seal the UBB mine," says MSHA spokeswoman Amy Louviere. "A meeting is set for May 5 to discuss the plan for sealing the mine."
Massey has yet to respond to NPR's request for comment.
