The Beneficial Use of Coal Ash has become a common practice in recent years throughout Pennsylvania. Coal ash that was primarily landfilled or dumped on waste piles has now become a viable product for mine reclamation, mine drainage pollution abatement and control, structural fill, construction related products, and various other projects. The promulgation of new residual waste regulations by the Pennsylvania Department of Environmental Protection (DEP) has been one of the main reasons for some of the new coal ash uses, but the utilization of fluidized bed combustion by power plants has also been a significant factor in the development of new beneficial uses for coal ash. Although most coal ash can be utilized for some sort of beneficial use, not all coal ash meets regulatory requirements for beneficial use. For a coal ash to be utilized beneficially it must first meet several regulatory guidelines, parameters and requirements. These regulatory guidelines, parameters and requirements address the chemical and physical properties of the coal ash, and these properties as well as the type of coal or coal refuse being burned, help determine how a specific coal ash can be utilized beneficially. The current beneficial uses of coal ash are consistently being utilized to help solve environmental and safety related problems, and future beneficial uses are being developed for even more environmental and safety related projects. All of these beneficial uses open up significant landfill space, reduce power plant and electrical related production costs; while helping reclaim and correct environmental and safety related problems.
