TENNESSEE VALLEY AUTHORITY (TVA) — HIWASSEE HYDRO PLANT (HIH) — NPDES PERMIT
NO. NCO027359 — PERMIT RENEWAL APPLICATION AND WAIVER REQUEST
Enclosed is one signed and two copies of a complete NPDES permit renewal application for HIH,
including EPA Form 1, site map, Form 2C, wastewater flow schematic, and Form 2E. There have
been no changes since the issuance of the last permit.
Ouffalls 003 and 004 discharge wastewater from generator air and bearing cooling water. The
characteristics of the discharge are expected to be similar. Therefore, estimated values, where
noted, have been provided on Form 2E for Outfall 003 based on sample data collected at Outfall
004.
Waiver Request — Form 2C — Outfall 002
Per Title 40 CFR § 122.21(g)(7)(iv), the Director may waive the reporting requirements for individual
point sources for one or more of the pollutants listed if the applicant can demonstrate that such a
waiver is appropriate because information adequate to support issuance of a permit can be obtained
with less stringent requirements. TVA requests that sampling be waived for Draft Tube Unwatering
Operations (Outfall 002) due to infrequency of discharges and water composition. Draft Tube
Unwatering Operations typically occur only during outages, approximately every two years, and
consists of river water that is unlikely to contain any contaminants from plant operations.
Historically, Outfall 002's infrequent discharges have been successfully managed through the
implementation of Best Management Practices per HIH's NPDES permit.
TVA requests a 30-day period between the issuance date and the effective date of the renewal
permit to facilitate internal distribution of the permit. If you have questions or would like additional
information, please contact Crystal Bishop by email at [e-mail].

8.1
Describe the nature of your business.
Hiwassee Hydro Plant is a two unit hydroelectric generating plant on the Hiwassee River with a generating capacity
of 24 megawatts. TVA's conventional hydro plants typically include a dam to control the flow of a river, a
•�
powerhouse containing turbines and generators to make electricity, a switchyard to step up the electricity's voltage
for distribution to customers and a reservoir of water behind the dam. Water from the reservoir flows through a
M
penstock impacting the blades of a turbine, which rotates the turbine. A large diameter shaft connects the rotating
u
turbine to a generator in the powerhouse. The generator consists of a large rotating electromagnet located in the
m
middle of a set of stationary wire coils. When running at the proper speed, electricity is produced in the coils at
Z
approx. 13,000 to 23,000 volts. Generator leads take electricity to the switchyard where voltage is increased and
transmitted to distributors across the Tennessee Valley. Water used to turn the turbine then flows out of the
powerhouse in a draft tube where it is released into the water supply. Hiwassee Hydro Plant has two units, one

003-A Temperature and pH monitoring locations — The receiving water temperature is measured in the tailrace near the plant
Qtail deck. The raw cooling water source is lake water flowing into the penstock. Therefore, the ambient upstream
temperature is based on a sample collected from the raw cooling water system prior to passing through the coolers.
The generator air and bearing cooling water combine within the dam structure at a point that is inaccessible for
sampling. Therefore, they are monitored separately. Alphanumeric designation above or in close proximity to the
triangle denotes the unique identifier assigned to the sampling location.
