The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC 1251, et seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
B=ass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which

consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a'manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling
point Flow measurement between sampleintervals shall be determined by use of a flow recorder and
totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the
expected total daily flow at the treatment system, or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. ' This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.

In accordance with (4) above, influent grab samples shall not be collected more than once per hour.
Effluent grab samples shall not be collected more than once per hour except at wastewater treatment systems
having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at
intervals evenly spaced over the 24-hour period that are equal in number: of hours to the detention time of the
system in number of days. However, the interval between effluent grab samples may not exceed six hours nor
the number of samples less than four during a 24-hour sampling period
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean
concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all
grab samples collected during that period. (40 CFR 122.2)
Daily Maximum
The highest "daily discharge' for conventional and other non -toxicant parameters. NOTE: Permittees may not

Daily SaMlin
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit The Division expects that sampling shall be conducted on weekdays except where holidays or other
disruptions of normal operations prevent weekday sampling. If sampling is required for all seven days of the week
for any permit parameter(s), that requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWO or "the Division"
The Division of Water Quality, Department of Environment and Natural Resources.
EMC

Backaround:
The Chatuga Hydro Plant produces electricity via hydraulic turbine generation. The facility produces an
average of 75.8 megawatt -hours per day of power, with peak power generation at 289 megawatt -hours
per day. The Asheville Regional Office notes that most of the Hiwassee River's flow is run through the
facility for power production.
The plant has three permitted outfalls as follows:
001: waters from the station sump
002: waters from the unwatering sump
003: once through cooling water
None of the outfalls contain a limit for flow and all employ Best Management Practices (BMPs) rather
than monitoring for pH, oil and grease, and temperature. BMPs are accepted to confirm compliance as a
result of the physical construction of the hydroelectric dam. Each DMR report contains a statement
affirming that BMPs are being used on site. The staff report and permit fact sheet from the 1998 permit
indicate that a general permit is not entirely appropriate for this facility.
Instream Monitoring and Verification of Existing Conditions and DMR Data Review:
This facility discharges to the Hiwassee River (classified C) in sub -basin 04-05-01 (Hiwassee River
Basin). The facility does not currently perform instream monitoring. Discharge Monitoring Reports
(DMRs) for flow (the only monitored parameter) were reviewed from 2010 to June 2012. Average flows
from the three outfalls are displayed below:

Outfalls 001 and 002. Oil absorbent pads are used in sumps and points of equipment oil
leaks. These pads are changed at least once a quarter in addition to the removal of
sediment to ensure that excessive pollutants are not discharged to surface waters of the

9. Principal product(s) produced: Electric Power
Principal raw material(s) consumed: N/A
Briefly describe the manufacturing process(es):
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 large reservoir of water behind the dam.
Water from the upper reservoir flows through a penstock (a large pipe connecting the reservoir
to the powerhouse) impacting the blades of a turbine. Water impacting the blades makes the
turbine rotate. A large diameter shaft connects the rotating turbine to a generator in the
powerhouse. The generator consists of a large rotating electromagnet (driven by the turbine)
located in the middle of an even larger set of stationary wire coils. When running at the proper
speed (typically around 100 revolutions per minute for TVA hydro generators), electricity is
produced in the coils at anywhere from about 13,000 to 23,000 volts. Generator leads take the
electricity to the switchyard where the voltage is increased and put into the TVA transmission
system for delivery to distributors across the Tennessee Valley. The water used to turn the
turbine then flows out of the powerhouse in a draft tube where it is released into the water
supply. Chatuge Hydro Plant has one conventional hydroelectric generating unit.

The ARO has the following comments regarding NPDES Permits NCO027359 and NCO027332:
Both of these facilities could/should be covered under general permits, but several years ago TVA
insisted on individual permits. It is our recommendation that these facilities be covered under the
NCG500 permit; however, if we can't do that, then the monitoring requirements should be changed to
reflect the monitoring requirements of the general permit. I have talked with Susan W. about this and
she agrees.

BACKGROUND
The Chatuga Hydro Plant produces electricity via hydraulic turbine generation. The facility
produces an average of 60 megawatt -hours per day of power, with peak power generation at 216
megawatt -hours per day. The Asheville Regional Office notes that most of the Hiwassee River's flow is
run through the facility for power production.
The plant has five permitted outfalls as follows:
001: waters from the station sump
002: waters from the unwatering sump
003: once through cooling water
None of the outfalls contain a limit for flow and all employ Best Management Practices (BMPs)
rather than monitoring for pH, oil and grease, and temperature. Each DMR report contains a statement
affirming that BMPs are being used on site. The staff report and permit fact sheet from the previous
permit indicate that a general permit is not entirely appropriate for this facility.
Instream Monitoring and Verification of Existing Conditions and DMR Data Review
This facility discharges to the Hiwassee River (classified C) in sub -basin 04-05-01 (Hiwassee
River Basin). The facility does not currently perform instream monitoring. Discharge Monitoring
Reports (DMRs) for flow (the only monitored parameter) were reviewed from 1998 to present. Average
flows from the five outfalls are displayed below:
Flow (MGD) 0.36 0.0 0.648
Correspondence
The Asheville Regional Office (ARO) did not conduct any site visits to this facility over the term
of the permit. Other than the required certification from the facility that BMPs are in place, there was no
correspondence noted from 1998 to present.
Fact SlheCL
i'a-c I

' The 1998 staff repo , ,am ARO indicates that the facility quay,_,,fora general permit. The
Permittee has historically requested an individual permit since such a permit would allow for
implementation ofBMPs.
PERMITTING STRATEGY
Waste Load Allocation (WLA)
The Division prepared the last WLA in 1985. The previous and current effluent limits were
based on guidelines and water quality standards. The Division has judged previous parameters and limits
to be appropriate for renewal. The draft 2002 Hiwassee River Basinwide Water Quality Plan reports
that the receiving stream is currently supporting all designated uses and provides no recommendations
for this discharger.
Reasonable Potential Analysis (RPA)
Since toxicants are not monitored in this discharge, no reasonable potential analysis was
performed.
SUMMARY OF PROPOSED CHANGES
The Permittee has not requested any changes. A special condition will be added requesting that the Permittee
take four samples at 001 and 002 for oil and grease and pH to determine whether or not the discharge is having
any impact on the receiving stream. These samples should be spaced out over the life of the permit.
PROPOSED SCHEDULE FOR PERMIT ISSUANCE
Draft Permit to Public Notice: May 1, 2002
Permit Scheduled to Issue: June 21, 2002

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and 0) and 15A NCAC 02H .0903(b)(11)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization maybe the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [I 5A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.

transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants;
and
2. Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
3. For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent
introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or
quality of effluent to be discharged from the POTW.
Section C. Municipal Control of Pollutants from Industrial Users.
1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from Industrial Users
discharging to the POTW may be present in the Permittee's discharge. At such time as sufficient information
becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent
limitations for any or all of such other pollutants in accordance with best practicable technology or water quality
standards.
2. Prohibited Discharges
a. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibition against the
introduction of pollutants or discharges into the waste treatment system or waste collection system which
cause or contribute to Pass Through or Interference as defined in 15A NCAC 02H .0900 and 40 CFR 403. [40
CFR 403.5(a)(1)]

(2) Pollutants which cause corrosive structural damage to the POTW, but in no case discharges with pH lower
than 5.0, unless the works is specifically designed to accommodate such discharges;
(3) Solid or viscous pollutants in amounts which cause obstruction to the flow in the POTW resulting in
Interference;
(4) Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a Discharge at a flow rate
and/or pollutant concentration which will cause Interference with the POTW;
(5) Heat in amounts which will inhibit biological activity in the POTW resulting in Interference, but in no
case heat in such quantities that the temperature at the POTW Treatment Plant exceeds 40°C (104°F)
unless the Division, upon request of the POTW, approves alternate temperature limits;
(6) Petroleum oil, non -biodegradable cutting oil, or products of mineral oil origin in amounts that will cause
Interference or Pass Through;
(7) Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that
may cause acute worker health and safety problems; or
(8) Any trucked or hauled pollutants, except at discharge points designated by the POTW.

The permit does not require them to monitor at all except for flow which is an estimate. They can state that they follow
BMPs, but they don't seem to state that anywhere on eDMR either. They requested to only have to maintain DMRs at
the facility like the general permit. They don't realize that eDMR is required by EPA. Otherwise, they would have to have
a waiver not to report. The general permits will have to report by eDMR in the future. What I gathered is that 2 out of 3
of these facilities are operated remotely. Should they be required to monitor the parameters in the permit? Would the
general permit be more appropriate for the TVA? Should they be given the general permit tables? It's hard to reconcile
blank boxes in an effluent table in the age of eDMR.

TENNESSEE VALLEY AUTHORITY (TVA) - CHATUGE HYDRO (CTH)- NPDES PERMIT NO.
NCO027332 - PERMIT RENEWAL APPLICATION
Enclosed are one signed original and two copies of a complete NPDES permit renewal
application for CTH. There have been no changes since the issuance of the last permit.
Solids may be removed from the station sump manually or using a vacuum truck or similar
device. The waste is analyzed for hazardous constituents and characterized for appropriate
disposal. Any oil absorbent materials removed from the station sump are handled in a similar
manner.
TVA requests that the following, which is consistent with language currently in General Permit
No. NCG500000 for discharges associated with hydroelectric ,operations, be included in the
renewed NPDES permit for CTH:
Submittal of monthly Discharge Monitoring Reports (DMRs) shalt not be required except
upon demand by the Division. This section supersedes the requirement for submitting
monthly Discharge Monitoring Reports (DMRs) specified in Part ll., Section D.2. of this
permit. Even though the submittal of the monthly monitoring reports to the Division is
suspended, all monitoring requirements remain. The data will be maintained on site for a
period of not less than three years.
TVA requests a 30-day period between the issuance date and the effective date of the reissued
permit. If you have questions or need additional information, please contact Mike Stiefel by

9. Principal product(s) produced: Electric Power
Principal raw material(s) consumed: NIA
Briefly describe the manufacturing process(es):
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 large reservoir of water behind the dam.
Water from the upper reservoir flows through a penstock (a large pipe connecting the reservoir
to the powerhouse) impacting the blades of a turbine. Water impacting the blades makes the
turbine rotate. A large diameter shaft connects the rotating turbine to a generator in the
powerhouse. The generator consists of a large rotating electromagnet (driven by the turbine)
located in the middle of an even larger set of stationary wire coils. When running at the proper
speed (typically around 100 revolutions per minute for TVA hydro generators), electricity is
produced in the coils at anywhere from about 13,000 to 23,000 volts. Generator leads take the
electricity to the switchyard where the voltage is increased and put into the TVA transmission
system for delivery to distributors across the Tennessee Valley. The water used to turn the
turbine then flows out of the powerhouse in a drank tube where it is released into the water
supply. Chatuge Hydro Plant has one conventional hydroelectric generating unit.

Dear Ms. Cothron:
On October 21, 2016 I conducted a Compliance Evaluation Inspection of the NPDES Discharge Permit that

The assistance of Steve Williams in conducting the inspections was greatly appreciated. Please refer to the
enclosed inspection report for additional observations and comments. If there are questions or additional
information is needed, please feel free to contact me at 828-296-4500.

Dear Ms. Kiesau:
INTERGOVERNMENTAL REVIEW - TENNESSEE VALLEY AUTHORITY (TVA) -
PROPOSED MODERNIZATION AND OPTIMIZATION OF HYDRO GENERATION AT
CHATUGE HYDROPLANT
Enclosed is a short description of options TVA is considering for the rehabilitation, modernization
and optimization of the Chatuge hydroplant in Clay County, North Carolina. TVA is planning to
prepare an environmental assessment (EA) around these alternatives. Previously the agency had
included the Chatuge project as a portion of the EA titled, "Optimizing the scheduling and use of
hydropower generation during periods of high cost replacement energy (peak generating periods),"
which was conducted in order to assess potential effects for a proposal to optimize operations of
existing generating units (including the one at Chatuge). We did not, however, include Chatuge in
the Finding of No Significant Impact (FONSI) for that EA in order to address questions posed by
the U. S. Fish and Wildlife Service. Subsequent to the preparation of that EA, TVA's River
Operations has proposed the modernization of the Chatuge turbine which would include the
replacement of the existing unit with a new one. Because both actions are foreseeable and
potentially affect the same resources, TVA has decided to combine consideration of optimization
of operations and modernization of the turbine at Chatuge hydroplant within a single EA.
TVA plans to complete a draft EA for comment in the autumn of year 2000 and, if no significant
impacts are identified, a final EA by the end of the calendar year. We would appreciate your
comments regarding issues and alternatives. yor further information, to provide comments, or to
request a copy of the subiect draft EA, contact Bruce Yea era 632-8051, direct mai to

OPTIMIZATION OF OPERATIONS AND MODERNIZATION
OF THE GENERATING UNIT AT CHATUGE HYDROPLANT
ENVIRONMENTAL ASSESSMENT (EA)
Purpose and Need For TVA Action
In 1995, the Tennessee Valley Authority (TVA) predicted that meeting consumer demand for
power would require an additional 16,500 megawatts (MW) in capacity by the year 2020
Hydropower, the most economical source of producing electricity available in the Tennessee
Valley, was identified as a major component of TVA's ability to meet future peak power needs. At
various hydropower projects, TVA is investigating ways in which to 1) optimize operations of
hydro generating units by scheduling their use to minimize the cost of replacement power that
would have to be generated by other more expensive or less environmentally desirable means, and
2) modernize,' rehabilitate and upgrade its aging hydropower generation facilities. Eventually, as
many as 88 hydro turbine units at 24 plant sites may be rehabilitated and modernized. These units,
such as those at Chatuge hydroplant, have an average age of over 50 years.
Brought into commercial operation in 1954, the turbine and generator unit at Chatuge hydroplant
needs to be upgraded to maintain safe and reliable generating capacity, improve operational
efficiency, and provide additional generating capacity. As a source of peaking power, the
efficiency improvements and capacity gains will help meet the projected peak energy demands in
the Tennessee Valley. Rehabilitation and modernization activities are intended to add 30 years to
the operational life of the Chatuge unit and provide additional megawatts hours (MWH) of
generating capacity. As agreed to in discussions with U. S. Environmental Protection Agency
(USEPA) and the State of North Carolina, TVA proposes to conduct the turbine rehabilitation or
modernization in conjunction with an outage to replace a leaking grease bearing in the year 2003.
Preliminary Alternatives Under Consideration
TVA earlier prepared an EA on the optimization of operations at 22 hydroplants and issued a
Finding of No Significant Impact (FONSI) for the proposed changes at 19 of those hydroplants
throughout the Tennessee and Cumberland River systems. Although Chatuge was one of the 22
hydroplants assessed in the EA, it was not included in that FONSI in order to address questions
raised by the U. S. Fish and Wildlife Service (USFWS) which required additional study at that
hydroplant. Because both actions are foreseeable and potentially affect the same resources, TVA
has decided to combine consideration of optimization of operations and modernization of the
turbine at Chatuge hydroplant within a single EA.
Within the scope of optimizing operations, as well as refurbishing and modernizing of the existing
generating unit at Chatuge hydroplant to provide additional peaking power, TVA is considering
four preliminary alternatives. None of the alternatives affect reservoir pool levels. The range of
alternatives includes:
Alternative A. No Action
TVA would conduct those maintenance activities necessary to ensure the continued safe and
reliable operation of the existing generating unit to provide peaking power. The present generating
capacity of the unit (I I MW rating) would be maintained and no additional hours of operation at
Maximum Sustainable Load (MSL) would be included.

INFORMATION SHEET INFORMATION SHEET
Alternative B. Optimization
The present generating capacity of the unit would be maintained and the maintenance activities of
Alternative A would be conducted. Operations of the existing generating unit would be optimized
to include up to an additional annual 600 hours of operation at presently occurring MSL.
Alternative C. Modernization
TVA would modernize the unit to increase generating capacity. The range of higher capacity
ratings under consideration are to uprate the unit to 13 MW, 14.5 MW, 16 MW or 17 MW. No
additional hours of operation at MSL would be included. The proposed outage for modernization
would begin in April 2003 and be completed in August 2003. During the outage a minimum flow
would be maintained with 1) use of the emergency minimum flow pump system (30 cfs capability)
TVA purchased specifically for outages at the single turbine hydroplants in the Hiwassee River
drainage, or 2) spill from Chatuge Dam. Passage of higher flows for any purpose would require
spill from Chatuge Dam during the outage.
Alternative D. The Proposed Action - Combined Optimization and Modernization at 14.5 MW
TVA would modernize the unit to increase generating capacity to 14.5 MW and include up to an
additional 600 hours of operation at MSL. The proposed outage schedule and methods of river
flow management would be as described for Alternative C.
Issues to be addressed in the Environmental Assessment
The following potential resource issues were identified in scoping by internal TVA staff and in
discussions with USFWS, state agencies and interested parties with regard to the optimization of
peaking operations at Chatuge.
• Flow alterations and their effects on erosion potential and aquatic habitat
• Water quality including thermal alterations
• Outage effects on resources
• Aquatic ecology including fish, benthic and mussel communities
• Potential presence of listed threatened or endangered species
• Recreation
• Cultural resources
• Visual resources
• Navigation
• Flood Control
• Terrestrial resources (riparian)
• Solid Waste Disposal
Comments and Requests For Information
TVA plans to complete a draft EA for comment in the autumn of year 2000 and, if no significant
