North Carolina Coal Ash Disposal – Site Closure Option Analysis


In 2018, Duke Energy submitted to the North Carolina Department of Environmental Quality its analysis of options for the closure of eight of its coal ash basins spread over six sites. The Southern Environmental Law Center commissioned Synapse Energy Economics, Inc. to review Duke’s Summary Reports and the Company’s analysis on trucking impacts, community and regional impacts, environmental impacts, and the estimated closure costs and schedules. Our resulting report describes how Duke's evaluation framework was designed to skew results in favor of its “Closure-in-Place” option, and in fact, to effectively ignore environmental impacts and risks. On April 1, 2019, the North Carolina Department of Environmental Quality ruled that Duke Energy must remove all ash from existing unlined landfills and move the ash to new, lined landfills.
