SUMMARY
This facility maintains 4 outfalls (001, 002, 003, and 004) With the exception of outfall 004 (sump drain) the source
of water for the other outfalls is once through cooling water. The old permit stipulates that outfalls 001 through 003
monitor (with no limits) flow, temperature and pH. For the outfall 004 monitoring was required for oil and grease,
flow and pH; monthly average and daily maximum oil and grease limits were 15 mg/L and 20 mg/L respectively.
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 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:
Discharge monitoring reports were conducted for the years 2001 and 2002. Information for 2003 was not available
since facility is required to submit reports annually. 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. (formally Yadkin, Inc., a subsidiary of
ALCOA), operates a powerhouse (dam) on the Yadkin River known as the Tuckertown
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 local electric utility companies.
There have been no changes and/or modifications to this facility or the subject permit since
the permit was last issued. Although the applicant indicates that this facility is located in
Montgomery County (the dam actually connects Montgomery to Stanly County), it was mutually
agreed to several years ago by Alcoa personnel and DWQ staff that this facility should be listed in
the permit as being located in Stanly County. This allows for not only this dam, but all of Alcoa's
four (4) dams to be administered by one regional office, which also helps to simplify the
communications between the company and the division.
It is recommended that the permit be renewed as requested.
