Charleston, W.Va. (AP) -- The U.S. Environmental Protection Agency is requiring American Electric Power to conduct additional safety tests at a West Virginia coal ash impoundment.
EPA issued a statement Thursday saying agency contractors noted that the construction of the impoundments at AEP's Philip Sporn power plant is similar that used at a Tennessee coal ash impoundment that gave way last year, releasing about 5.4 million cubic yards of coal ash.
The federal agency wants AEP to conduct foundation and stability tests at the Mason County impoundments.
EPA says the utility must submit a testing plan by Monday.
Utility spokeswoman Jeri Matheney said the impoundments have been inspected at least three times this year, but AEP will comply with EPA's request.
