Thank‐you Brad.  Until the issue is resolved (eDMR/permit modification), any monitoring that cannot be reported on the 
eDMR may be reported in the comments section as you referenced in our conversation yesterday.  I will place a copy of 
your response in the file and this Notice of Deficiency will be closed. 

Please let me know if you have any questions.

Per our conversation there is no required action on behalf of TVA Fontana Hydro Plant and the subject NOD can be 
closed.  The NOD references missing data from the September 2018 Discharge Monitoring Report (DMR) for Outfalls 
#004 and #005.  However, monitoring for parameters specified in the permit limits table for these outfalls is only 
required once per semi‐annual monitoring period (Jan‐June and July‐Dec) and would be reported in corresponding 
DMRs due in January and July for the monitoring period.   

Based on the e‐mail chain below, this has been a recurring issue since transferring over to electronic reporting.  Since we 
will be working with Derek Denard on a permit modification, I will take the opportunity to see if the reporting system 
can be updated so flags will not appear for these outfalls for quarterly DMRs submitted in April and October.        

If you could, please respond with your concurrence based on my understanding of our conversation and status of the 
NOD.

Hi Lisa, 

The circumstances with your permits have always been a bit problematic in terms of how a computer will catalog the 
requirements, and then perform an evaluation for compliance. The terms of the actual permits do not provide specificity 
as to the months when any monitoring is to be conducted. You can conduct monitoring within a three month window to 
satisfy the quarterly monitoring requirement, and anytime within a six month window for the semi‐annual requirement. 
Because you could report during any month, the computer is set up to allow for that, and will “look” for those reports 
each month. All currently seems to have worked well during the months you do quarterly reporting, because you’ve also 
reported a flow value for outfalls 003, 004 and 005 during those months (even if it’s not required). During months when 
no reporting is done, our computer system flags the facility for a missing report. When this happens, staff will go into the 
system and associate a “no action” code with the system‐generated “violation,” and add a comment that only quarterly 
monitoring is required. This is in our actual compliance system; eDMR is not a compliance tracking system, but it does 
acquire information from the compliance system (called BIMS) and allows for an evaluation of the reported data in the 
validation process. That’s what leads to the validation errors the eDMR system produces. As Michele stated in her reply, 
those messages can be ignored and you can move forward in submitting your DMR. 

I believe someone in your company has been in touch with Charles Weaver in our office about the situation. There may 
be particular ways to report that will not be burdensome to you, that may satisfy the computer’s desire for data. There 
may also be other ways the permit conditions could be written that would be more conducive to the way the computer 
evaluates data. Perhaps that can be done during the upcoming permit renewal process. 

I’m sorry to be the one bearing this news. We continue to look for a solution to implement that will satisfy all the 
demands arising from the terms of the permits and those of eDMR, BIMS, and ICIS (EPA database). Until then, I believe 
you can submit eDMRs that show validation errors with confidence, although you may wish to add a further comment to 
the data regarding the reporting requirement. We’ll keep an eye on things here to help ensure you see no negative 
consequences due to this situation. 

Thank you for your patience. I hope this helps. 

Bob

Lisa, 
I don’t think the system recognizes the frequency for these outfalls and that’s why you are seeing these warnings. 
Validation warnings don’t prevent you from Certifying & Submitting the data. As long as you have entered data based on 
your permit you should be okay. If you want to double ‐check on this situation you can call Janet Cantwell at 828‐296‐

Thank you, I appreciate it. I have another question: I received the following error message when I validated the report. 
Outfalls 003, 004, & 005 have semiannual reporting requirements (July and December). Is the system going to interrupt 
“no data” as an error on my part? Am I going to need to enter data for these even though they are semiannual?

Dear Ms. Thedford:
TENNESSEE VALLEY AUTHORITY (TVA) - FONTANA HYDRO (FNH) - NPDES PERMIT NO.
NC0027341 - PERMIT RENEWAL APPLICATION
Enclosed are one signed original and two copies of a complete NPDES permit renewal
application for FNH. 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 FNH:
Submittal of monthly Discharge Monitoring Reports (DMRs) shall not be required except
upon demand by the Division. This section supersedes the requirement for submitting
monthly Discharge Monitoring Reports (DMRs) specified in Part II., 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 Brad Love by email
at [e-mail] or by phone at [phone].

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. Fontana Hydro Plant has three conventional hydroelectric generating units.

annual monitoring requirement for Outfalls 003, 004, and 005, TVA discovered the
generator air cooling water and generator bearing cooling water combine within the
dam structure at an inaccessible location for sampling. TVA has installed sampling
taps on each of these cooling water systems per unit and proposes the permit be
modified to split these outfalls into an A and B component where A represents the unit
generator air-cooling water and B represents the unit generator bearing cooling water.
TVA also requests references to quarterly monitoring and reporting in Footnote 1.b. on
page 5 of 9 for Outfalls 003, 004, and 005 be replaced with a description for semi-
annual monitoring and reporting to be consistent with the measurement frequency for
these outfalls in the effluent limitations table. TVA believes the current language in the
permit is an administrative oversight.
If you have questions or need additional information, please contact Brad Love by
email at [e-mail] or by phone at [phone].

7. Describe the treatment system List all installed waste treatment components with capacities,
describe the processes that generate wastewaters. If the space provided is not sufficient attach a
separate sheet of paper with the system description.
Water discharged from the draft tube unwatering operations, powerhouse floor drains,
penstock envelope leakage and wheel pit leakage make-up the flows into the sumps for
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
State. It is assumed that the oil absorbent pads treat 100% of the oil and grease volume
before discharge.
8. Is facility covered under federal effluent limitation guidelines? No ® Yes ❑
If yes, specify the category?
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. Fontana Hydro Plant has three conventional hydroelectric generating units.
