Inside This Month's Issue
Coal Combustion Residuals Regulation by Jim Roewer Over 130 million tons of coal combustion residuals (CCRs)—inorganic material in coal that is not consumed or emitted as
gaseous emissions when coal is combusted and is captured by pollution control equipment as fly ash, bottom ash, boiler
slag, and flue gas desulfurization material—are produced annually in the United States. In 2011, 43.5 percent of captured CCRs were used in a variety of applications, including cement and concrete, structural fills, road base, wallboard manufacture, and mine land reclamation. CCRs that aren’t beneficially used are typically disposed of in landfills and surface impoundments. The question of how to best regulate CCRs under the federal Resource Conservation and Recovery Act has long been a vexing issue for the U.S. Environmental Protection Agency and Congress.
