TVA Plans Improvements for Management of Onsite Water at Bull Run

Jul 2, 2019

KNOXVILLE, Tenn.­­ – The Tennessee Valley Authority is planning projects to improve the handling of wastewater and storm water flows at its Bull Run Fossil Plant near Clinton, Tennessee.

The projects include an interim plan to close the main ash impoundment in place and turn a section of the impoundment into a temporary process water basin. This interim solution would be in place until a permanent decision is made on the management of the underlying coal combustion residuals.

The current stilling pond would be permanently closed, with ash removed to an existing onsite landfill, and turned into the permanent process water basin.

Details are included in a final Supplemental Environmental Assessment issued on July 2, along with a Finding of No Significant Impact. Those documents are available at

TVA has not made any final decisions on permanent closure of the main ash impoundment at Bull Run. TVA is conducting an environmental investigation at the site under the direction of the Tennessee Department of Environment and Conservation, which will help evaluate how coal combustion residuals are managed at the Bull Run. Details of that study are available at
