Utility Byproducts Used For Acid-Mine-Drainage Abatement At Mettiki Coal

Electric utility response to certain amendments of the Clean Air Act has resulted in a production of several types of alkaline coal combustion byproducts (CCB). Alkaline combustion byproducts are gaining increasing usage for acid mine drainage (AMD) mitigation as research leads to a better understanding of their beneficial applications. Since January 1997, Mettiki Coal has been injecting alkaline flue gas desulfurization material from Virginia Power's Mt. Storm Unit No. 3 wet limestone scrubber into abandoned portions of the active Mettiki Mine.
