Huntsville Sewer Line

Limestone County, Alabama

On April 20, 2012, TVA issued a finding of no significant impact for its Section 26a approval of an 86-foot-long sewer line proposed to be built by the City of Huntsville on piers across Limestone Creek, in Limestone County, Alabama.  TVA cooperated with the U.S. Army Corps of Engineers in the development of an environmental assessment (EA) of the sewer line crossing.  The EA, which was finalized on February 8, 2012, focused on potential impacts to water quality and two endangered snail species which occur in the stream.  The Biological Opinion issued by the U.S. Fish and Wildlife Service concluded that the project was not likely to jeopardize the existence of the endangered snails, provided conservation measures and other conditions were implemented.  TVA Section 26a approval will require the City to implement construction best management practices, comply with standard and general conditions of the Section 26a Permit, and adhere to special conditions and requirements.
