Coal Ash Ponds The Romeo and Juliet Story of Coal Fired Power Plants Society sees them as toxic together, but currently, one cannot exist without the other. The only option is death.
Coal Ash Ponds: Impoundments created near the power plant to store or dispose of ash from combustion of coal. Ash solids settle, leaving water at the surface to be recycled or discharged. Pond at Mountain Island Lake Pond at Buck Steam Plant
