Environmental Assessment - Tennessee Valley Authority

The Tennessee SHPO commented by letter dated June 29, 2009, that in order to complete
a review of the project, the SHPO would require the recommendation of TVA’s Cultural
Resources staff. On March 23, 2011, TVA sent a letter to the SHPO stating that the water
intake and pipeline would not adversely affect historic structures eligible for or listed in the
NRHP. In a letter dated April 4, 2011, the SHPO concurred that the project would have no
effect.
