* 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 30th
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.

Confirmation that a visual inspection was conducted shall be recorded in the operating log for the facility and provided to the Division upon request.
2. There is no limit for effluent pH, however annual monitoring shall be required.
Best Management Practices (BMPs) must be employed to ensure that excessive pollutants are not discharged to the surface water of the state. These practices
should include as a minimum, routine maintenance of the rope skimmer type oil/water separator and cleaning accumulated sediment in the bottom of the sump
annually.
Chemical wheel pit cleaning is permitted on a monthly basis. When wheel pit cleaning occurs, the tailrace shall be inspected visually for foam and oil. Cleaning shall be
conducted only with pre -approved solvents. Should the Permittee wish to change solvents, a written'request should be made to the Division including the MSDS for the
proposed solvent.
Mechanical cleaning operations, which do not contribute any wastewater to the discharge are not limited by this permit. Non -discharging cleaning operations may be
conducted as often as necessary to ensure safety and proper facility operation.
The Permittee shall obtain authorization from the Division prior to the use of any chemical additive (i.e. biocides) 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 Biocide Worksheet Form 101 (if applicable), a copy of the MSDS

SUMMARY
This facility maintains 6 outfalls (001, 002, 003, 004, 005 and 007) With the exception of outfall 007
(sump drain) the source of water for the other outfalls is once through cooling water. The old permit
stipulates that outfalls 001 through 005 monitor (with no limits) flow, temperature and pH. For the
outfall 007 monitoring was required for oil and grease, flow and pH.
The receiving stream, Yadkin River, is classified as WS-IV and B CA waters, from a point 0.6 mile
upstream of the High Rock Lake Dam to the Badin Dam. This reach is not listed on the 303(d) list as
impaired water. According to the March 2003 Yadkin -Pee Dee River Basinwide Water Quality
management Plan this reach has been classed as supporting its designated uses.
TOXICITY TESTING:
Current Requirement: N/A
Recommended Requirement: N/A
COMPLIANCE SUMMARY:
DMR data and correspondence for the past two years have been reviewed. With the available
information it was concluded that this facility has no compliance issues.
INSTREAM MONITORING:
This facility is not required to perform any instream monitoring.

PART IV - EVALUATION AND RECOMMENDATIONS
The applicant, Alcoa Power Generating, Inc. (formallyYadkin, Inc., a subsidiary of
ALCOA), operates a powerhouse (dam) on the Yadkin River known as Falls 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 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.
issued.
There have been no changes and/or modifications to this facility since the Permit was last
It is recommended that an NPDES Permit be renewed as requested.
