The Tennessee Valley Authority is seeking public input on a study for closing coal ash storage sites.
The agency wants input on the scope of its Environmental Impact Statement to address the disposal of ash and other coal combustion residuals at its coal plants.
CCRs are byproducts from the burning of coal or its emissions, such as fly ash.
The purpose of the EIS is to help TVA comply with the CCR Rule issued by the U.S. Environmental Protection Agency in April.
It will consider the impacts of two primary closure methods, as well as examine the impact of closing 11 of TVA's impoundments within three years.
Comments may be submitted online at http://www.tva.gov/environment/reports/ccr/ , or emailed to CCR@tva.gov.
TVA supplies power to about 9 million people in Tennessee, Alabama, Mississippi, Kentucky, Georgia, North Carolina and Virginia.
