NOTES:
* Sample Location: E — Effluent or at the point closest to discharge where a representative sample of the discharge can feasibly be obtained.
1 The temperature of the effluent will be regulated so that the temperature of the receiving stream does not increase by more than 2.8 °C above the natural water
temperature. In no case should the receiving stream temperature exceed 32 °C due to the facility's operation. Temperature of the effluent may be obtained anywhere
downstream of the heat exchanger effluent that is representative of the discharge.
2 The pH of the effluent shall not be less than 6.0 standard units nor greater than 9.0 standard units, unless ambient river conditions prevent compliance with this range.
The Permittee shall obtain authorization from the Division prior to the use of any chemical additive in the discharge. the permittee shall notify the Director in
writing at least ninety (90) days prior to instituting the use of any additional additive in.the discharge which may be toxic to aquatic life (other than additives
previously approved by the division). Such notification shall include the completion of a Biocide Worksheet Form 101 (if applicable), a copy of the MSDS for the
additive, and a map indicating the discharge point and receiving stream.
Monitoring results obtained during the calendar year shall be recorded and reported on a Discharge Monitoring Report (DMR) form and postmarked no later than January 3011'
following the completed reporting period. The first DMR is due January 30' 2001. Samples obtained for monitoring purposes may be collected anytime during the calendar
year.
There shall be no discharge of floating solids or visible foam (other than trace amounts) in the effluent, unless ambient river conditions prevent compliance.

PART IV - EVALUATION AND RECOMMENDATIONS
The applicant, Alcoa Power Generating, Inc. (formally Yadkin, Inc., a subsidiary of
ALCOA), operates a powerhouse (dam) on the Yadkin River known as the High Rock Powerhouse,
which until about six months ago generated hydroelectric power that was used in ALCOA's
aluminum manufacturing process. Due to poor economic conditions and the depressed global
aluminum market, ALCOA has since curtailed all manufacturing operations, and the dams are now
only used to produce hydroelectric power that is sold to the local electric utility companies.
There have been no changes and/or modifications to this facility or the permit since the
permit was last renewed.
It is recommended that the NPDES Permit be renewed as requested.

SUMMARY
This facility maintains 3 outfalls (001, 002 and 003). The source of wastewater for the outfalls is once through
cooling water. The old permit stipulates that outfalls 001 through 003 be monitored (with no limits) for flow,
temperature and pH. Discharge monitoring reports have to be submitted yearly.
The receiving stream (Yadkin River) is classified as WS-IV and B CA waters from a point 0.6 mile upstream of
High Rock Lake dam to Badin Dam. This reach is not listed on the 303(d) list as impaired water. However,
according to the March 2003 Yadkin -Pee Dee River Basinwide Water Quality management Plan this reach is
impaired due to low DO concentration.
