News release: “The U.S. Environmental Protection Agency =is proposing the first-ever national rules to ensure the safe disposal and management of coal ash from coal-fired power plants. Coal combustion residuals, commonly known as coal ash, are byproducts of the combustion of coal at power plants and are disposed of in liquid form at large surface impoundments and in solid form at landfills. The residuals contain contaminants like mercury, cadmium and arsenic, which are associated with cancer and various other serious health effects. EPA’s risk assessment and damage cases demonstrate that, without proper protections, these contaminants can leach into groundwater and can migrate to drinking water sources, posing significant health public concerns. [This] action will ensure for the first time that protective controls, such as liners and groundwater monitoring, are in place at new landfills to protect groundwater and human health. Existing surface impoundments will also require liners, with strong incentives to close the impoundments and transition to safer landfills, which store coal ash in dry form. The proposed regulations will ensure stronger oversight of the structural integrity of impoundments in order to prevent accidents like the one at Kingston, Tennessee. [This] action also will promote environmentally safe and desirable forms of recycling coal ash, known as beneficial uses.”
