The Tennessee Valley Authority has recently completed closure in place construction for their coal combustion residuals (CCR) disposal units at the retired Widows Creek Fossil Plant. The facilities included a gypsum stack, dredge cell, and ash pond. Find out more about lessons learned associated with dewatering, instrumentation monitoring, stormwater management, CCR handling, and CCR preparation during the closure process.
