Construction of this projeat wiil rec�uire impacts to waters oi the United States in the Watauga
River Basin. The existing bridg� cross Cove Creek {C�ass: C). The project is located within a
trout watershed. T�is project does not drain to designated critical habitat for the ellc toe mussel.
This project was rreviewed %r the presance af threatened a�d endangered species in the fiald and
� have also inciuded a query af the N�NHP c�atabase. Based an the project area mapped with my
request, the c�ata�ase search indicates that there are no records of any federally iisted threatened
ar ez�dangered species, impo�rtant na#ural communities, natural areas, or conservation/managed
areas within the proposed praject ba�ndary. The NLEB is listed as a protected species in this
county but the project does not fall r�vithin 0,25 miles of any red H[JC zdentified in the SLOPES
spelled out in the Nationwide Pertnit Regional Conditions. No clearing is needed. We do not
anticipate a�ay impact to any other fed�ally listed s�ecies.
CultUral resource campliance work has been completed. No archaeological resources or historic
properties witl be affected by t1�is project {see attacized).
The project impacts are not significant in nature and should not alter the hest usage for this
