PART IV - EVALUATION AND RECOMMENDATIONS
The applicant, Yadkin, Inc. (a subsidiary of ALCOA), operates
a powerhouse (dam) on the Yadkin River known as High Rock
Powerhouse, which generates hydroelectric power used in ALCOA's
aluminum manufacturing pror.PComplex electrical generation
machinery exists at this facility that requires cooling water
during operation.
There have been no changes and/or modifications to this
facility since the Permit was last issued (12/23/92). Please note
that this facility should be listed in Rowan County and not
Davidson County. It was initially decided between the MRO and
Raleigh Central Office that all of the dams operated by Yadkin,
Inc. would be maintained by one regional office even though the
dams actually bounded three (3) different regions. The goal was Qo
help simplify tracking between this agency and Yadkin, Inc. m id
minimize regional contacts.
r,
-J
It is recommended that an NPDES Permit be renewed as ko
requested.r
