| About two-thirds of the coal-ash dams across West Virginia might need repairs, a quarter of them are ranked as being in poor or unsatisfactory condition, according to the state Department of Environmental Protection.
The DEP reported that eight of the 20 coal-ash dams it examined were in satisfactory condition.
Inspectors found stability problems, seepage and erosion at some of the dams as part of a "comprehensive review" launched after the disastrous failure of a coal-ash impoundment in East Tennessee.
The DEP also found problems that resulted in at least five enforcement actions at landfills where dry waste products from coal-fired power plants have been dumped.
The Charleston Gazette says the 44-page DEP report says that the companies are taking the proper corrective action.
The DEP inspectors admitted that American Electric Power built two coal-ash dams at one Mason County site without the state knowing about it.
State dam-safety experts seldom inspect coal-ash dams in West Virginia, because state law does not require periodic reviews.
After the collapse of the Tennessee dam, the Charleston Gazette revealed that most of the coal-ash dams in West Virginia had not been visited by a state dam inspector in at least five years.
DEP Secretary Randy Huffman said his agency is exploring options for more frequent inspections.
