Tennessee Valley Authority, 1101 Market Street, BR4A, Chattanooga, Tennessee 37402 December 29, 2015 Mr. Vojin Janji6 Manager, Water-Based Systems Division of Water Resources Tennessee Department of Environment and Conservation William R. Snodgrass Tennessee Tower, 11lth Floor 312 Rosa L. Parks Avenue Nashville, Tennessee 37243

Dear Mr. Janji6:

TENNESSEE VALLEY AUTHORITY (TVA) - WATTS BAR NUCLEAR PLANT (WBN) - NPDES PERMIT NO. TN0020168 - APPLICATION REQUEST FOR PERMIT RENEWAL TVA requests that a renewal NPDES permit be issued for WBN operations, which will expire on June 30, 2016. Enclosed is an NPDES application package, which includes completed EPA Form 1, site map, Form 2C, flow schematic, and a permit address form. Sampling for the analytical data provided in this application occurred in August 2015 and historical data were compiled from the period of October 2012 through October 2015.

TVA would appreciate consideration of the following in the~renewed permit.

OSN 101 and OSN 102

1. As demonstrated by the historical data shown in Form 2C, WBN has consistently maintained compliance with permit limitations for Total Residual Chlorine (TRC). TVA requests that TRC monitoring be reduced to l/week in the renewal permit and believes this frequency is~

reasonable to show continued compliance during the next permit cycle.

2. WBN has also consistently maintained compliance with Zinc and pH limits and requests that monitoring requirements for these parameters be reduced to llmonth in the renewal permit.

TVA believes this frequency is reasonable to show continued compliance during the next permit cycle.

Mr. Vojin Janji6 Page 2 December 29, 2015 IMP 103 and IMP 107

1. TVA requests the following footnote be added to IMP 103 table for flow:

In the event that the continuous flow monitor is out of service, flow measurement shall be collected at a minimum frequency of 1/month via instantaneousflow meter reading or calculation based on pump logs.

2.. There were no metal cleaning activities during the previous permit cycle, and no metal cleaning activities are currently anticipated in the next permit cycle. However WBN commonly utilizes the Lined/Unlined Ponds to receive low volume wastewaters when operationally appropriate in addition or lieu of routing to the Low Volume Waste Treatment Pond (LVWVTP). The Lined/Unlined Ponds are in series that discharge intermittently through IMP 107, and the LVWTP discharges almost continuously through IMP 103. Refer to the enclosed flow schematic. Both IMP 103 and IMP 107 flow to the Yard Holding Pond (YHP),

which ultimately discharges to the Tennessee River via OSN 101. During instances when no metal cleaning activity has occurred, TVA requests the ability to release from IMP 107 to either the LWVTP or YHP without required monitoring for Copper, Iron, and Phosphorous.

TVA requests the following footnote to be added to IMP 107 table:

Sampling for copper, iron, and phosphorous are required only when metal cleaning activities have occurred within the Lined/Unlined Ponds since the last batch dischargefrom this outfall. Non-metal cleaning wastewaters from the Lined/Unlined ponds may be routed to the L VWTP without compliance monitoring.

OSN 113

1. WBN has consistently discharged Dissolved Oxygen (DO) above the instream water quality standard. TVA requests that DO monitoring at OSN 113 be removed in the renewal permit.

2..As demonstrated by the historical data shown in Form 20, WBN has consistently maintained compliance with permit limitations for Total Residual Chlorine (TRC) at OSN 113. A large volume of data is available since the Supplemental Condenser Cooling Water (SCCW) remains in service throughout the year, except during outage situations. TVA requests that footnote (5) be changed to only require TRC monitoring 1lweek in the renewal permit when the SCCW system is in operation. TVA believes this frequency is reasonable to show continued compliance during the next permit cycle.

Mr. Vojin Janji*

Page 3 December 29, 2015 Additional Requests

1. TVA requests that the following language be retained in Part l.A. to avoid the need for preparing a separate water quality certification for the Nuclea'r Regulatory Commission.

This TN-NPDES permit also constitutes the State's certification under Section 401 of the Clean Water Act for the purpose of obtaining any federal license for activities resulting in the dischargescovered under the TN-NPDES permit.

2. Enclosed is a summary of the Reasonable Potential (RP) evaluation and whole effluent toxicity test results since 1994. As further described in the RP evaluation, TVA requests no changes from the current biomonitoring conditions at OSN 101, 102, and 113 and that the permit language maintain consistent with the current Biocide Corrosion Treatment Plan (BCTP).

3. TVA requests the existing language found in Part III.F. for maintaining a Biocide/Corrosion Treatment Plan (B/CTP) be replaced with the following in the renewal permit. This language is consistent with that found in other TN-N PDES permits.

The use of toxic chemicals and biocides at the site for process and non-process flows shall be managed under a Biocide/CorrosionTreatment Plan (B/CTP). The B/CTP shall describe chemical applicationsand macroinvertebratecontrols, include all materialfeed rates, and proposedmonitoring schedule(s). The permittee shall conduct treatments of intake or process waters under this permit using biocides, dispersants, surfactants, corrosion inhibiting chemicals, or detoxification chemicals in accordance with conditions approved and specified in the B/CTP.

The permittee shall maintain the B/CTP at the facility and make the plan available to the permit issuing authority upon request. The permittee shall amend the B/CTP whenever there is a change in the application of the chemical additives or change in the operation of the facility that materiallyincreases the potential for these activities to result in a discharge of significantamounts of pollutants. The Division shall also be notified in writing within 30 days of any material changes that will change the active ingredients or quantities used of any such chemical additives.

4. The receiving stream for discharges from WBN (Tennessee River - Chickamauga Reservoir in Rhea County) is currently classified as an Exceptional Tennessee Water. For previously authorized discharges to such waters, TDEC Rule 0400-40-03-.06 requires a review of updated alternatives analysis information in cases where the discharge results in degradation above a de minimis level.

Mr. Vojin Janji6 Page 4 December 29, 2015 The withdrawal rate for the intake pumping station located in Chickamauga Reservoir will be approximately 75 MGD and the SCCW intake withdrawal rate will remain approximately 174 MOD. Of the total withdrawal of approximately 249 MOD, approximately 42 MGD is consumptive (primarily cooling tower evaporation) with the remainder returning to the stream via permitted outfalls. The consumption amounts to only 1.3% of the 7Q1 0 Stream flow (3173.3 MGD). Therefore, water withdrawals will continue to be de minimis as described in TDEC Rule 0400-40-03-.06.

No thermal degradation is proposed or anticipated. TVA has performed an extensive hydrothermal analysis of the WBN heat dissipation system. This analysis indicates that near-field (and thus far-field) thermal impacts are insignificant and can be managed within the limitations of the current NPDES permit.

TVA appreciates your consideration of the information provided herein in the development of the reissued permit. If you have any questions or need additional information, please contact Travis Markum by email at trmarkum~tva.gov or by phone at (423) 751-2795 in Chattanooga.

Chronic TOXICITY Step 1 20 WET Studies (10 years), Maximum Observed Toxicity is 3.7 TUc.

[Average toxicity = 3.50 TUc; compliance limit = 14.9 TUc (IC25 > 6.7%

effluent).]

Step 2-3 Coefficient of variation (CV) = 0.1. For 20 samples and a CV of 0.1, the multiplying factor (99% confidence level and 99% probability) is 1.2.

Step 4 Low stream flow plus WBN Outfall OSNt13 discharge = 2210.895 MGD and WBN Outfall OSNl13 discharge = 148.895 MGD = 6.73% Instream Waste Concentration (IWC) after mixing.

At a 0.0673 IWC: 3.7 TUc x 1.2 x 0.0673 = 0.30 TUc Step 5 0.30 TUc is less than the ambient CCC criterion of 1.0 TUc. This outcome demonstrates that no Reasonable Potential for excursions above the CCC exists, based on effluent data obtained from testing conducted under operating conditions for the past 10 years.

Chronic TOXICITY Step 1 20 WET Studies (10 years), Maximum Observed Toxicity is <8.9 TUc.

[Average toxicity = <7.1 TUc; current compliance limit = 35.71 TUc (IC25 >

2.8% effluent).]

Step 2-3 Coefficient of variation (CV) = 0.3. For 20 samples and a CV of 0.3, the multiplying factor (99% confidence level and 99% probability) is 1.6.

Step 4 Low river flow = 2062 MGD and WBN Outfall OSN101 discharge = 57.76 MGD = 2.80% Instream Waste Concentration (IWC) after mixing.

At a 0.028 IWC: 8.9 TUc x 1.6 x 0.028 = 0.40 TUc Step 5 0.40 TUc is less than the ambient CCC criterion of 1.0 TUc. This outcome demonstrates that no Reasonable Potential for excursions above the CCC exists, based on effluent data obtained from testing conducted under operating conditions for the past 10 years.

and OSN1 13 that are specified in the current Biocide Corrosion Treatment Plan (BCTP), with one test per outfall during oxidizing biocide treatment and one test per outfall during non-oxidizing biocide treatment. TVA is requesting permit language consistent with the BCTP.

The following RP determination utilizes 10 years (20 studies) of WET biomonitoring data collected for Outfalls 101 and 113. Table 1 summarizes Outfall 101 biomonitoring results while Table 2 summarizes Outfall 113 biomonitoring results.

TENNESSEE VALLEY AUTHORITY (TVA) - WATTS BAR NUCLEAR PLANT (WBN)

NPDES PERMIT NO. TN0020168 - APPLICATION FOR PERMIT RENEWAL Current Whole Effluent (WET) Toxicity Limits (permit effective 8/112011):

Outfall 101 - 7-day or 3-brood 1025 > 2.8% effluent (35.7 TUc)

Monitoring Frequency = 2/year Outfall 113 - 7-day or 3-brood 1025 ;* 6.7% effluent (14.9 TUc)

Monitoring Frequency = 2/year Proposed Whole Effluent (WET) Toxicity Requirements:

Outfall 101 - 7-day or 3-brood IC25 Ž 2.8% effluent (35.7 TUc)

Monitoring Frequency = 2/year, one during oxidizing biocide treatment and one during non-oxidizing biocide treatment Outfall 113 - 7-day or 3-brood IC25 > 6.7% effluent (14.9 TUc)

Monitoring Frequency = 2/year, one during oxidizing biocide treatment and one during non-oxidizing biocide treatment Outfalls 101 and 113:

In accordance with EPA's recommendation (Technical Support Document for Water Quality-based Toxics Control, EPA/505/2-90-001), and incorporating current flow rates associated with the operation of Unit 1 and Unit 2, WBN Outfall OSN101 and Outfall OSN113 would not be required to have chronic WET limits based on a demonstration of no Reasonable Potential (RP) for excursions above the ambient water quality chronic (CCC) criterion using effluent data for current operating conditions.

Following guidance in the Technical Support Document (TSD), when no RP exists, biomonitoring would be conducted at a frequency of only once every 5 years as part of the permit renewal process to document acceptable effluent toxicity and toxicity at the instream wastewater concentration (IWC), and would serve only as a hard trigger for accelerated toxicity biomonitoring.

However, raw water used at the facility is treated with corrosion inhibitors and biocide products. These products, which can become concentrated in the cooling tower system, are discharged through Outfalls 101 and 113. The chemical makeup of the products used can change during the permit period and the combined toxicity effect of the chemicals is not known. Thus it is not feasible to control toxicity only by the application of chemical specific effluent limits to the discharge. Toxicity testing is a reasonable method to evaluate the toxicity impacts of the products in the effluent. Therefore, TVA believes it is appropriate to incorporate the proposed WET requirements stated above for WBN Outfalls OSN101

WATTS BAR NUCLEAR PLANT TRITIUM PERMITTING INFORMATION ATTACHMENT As a nuclear powered generating station licensed to operate by the Nuclear Regulatory Commission (NRC), any and all of the liquid and gaseous effluents from Watts Bar that may contain radioactive material are subject to and regulated by the NRC. Therefore, radioactive releases from the operation of nuclear plants are outside the scope of the National Pollutant Discharge Elimination System (NPDES) program implemented under the Clean Water Act.

Specifically, the controls and limits for the release of radioactive material are established and regulated under the terms of 10 CFR Part 20, "Standards for Protection Against Radiation" and 10 CFR Part 50, "Domestic Licensing of Production and Utilization Facilities," and any such releases to the environment are controlled and monitored under the terms of the Watts Bar Operating License. Watts Bar-related liquid and gaseous effluents that may contain radioactive material are not addressed as part of the NPDES permitting process.

TVA has coordinated its NRC license-related activities with TDEC's Division of Radiological Health (DRH) and this includes the Tritium Project-related activities at Watts Bar. This coordination is not connected with the NPDES permitting process. A copy of TVA's License Amendment Request, dated August 20, 2001, was sent to DRH, describing TVA's plan to insert Tritium Producing Burnable Absorber Rods (TPBARs) into the Watts Bar Unit 1 reactor core to support the U.S. Department of Energy's program for maintaining the nation's tritium inventory. 1 Prior to each fuel cycle, TVA calculates the expected tritium release from TPBARs in establishing the number of TPBARs to be irradiated. This action assures that the annual limits and operating objective, as established in Watts Bar's Operating License, are not exceeded.

TVA's letter of March 22, 2005, to the NRC discussed higher than expected tritium permeation from the TPBARs into the reactor coolant system during the first operational irradiation cycle, and committed to monitor such levels to assure that cumulative tritium levels resulting from the TPBARs as well as non-TPBAR sources due to plant operations remained below established limits. To do so, TVA has limited the number of TPBARs so that the total tritium released remains below already approved regulatory limits.

TVA's March 22, 2005, letter was provided to the NRC for information only and did not require any licensing action on the part of the NRC. Since it did not change any of the effluent release commitments previously provided to DRH and there was no requirement to do so, therefore TDEC was not on distribution.

In sum, it is important to know that TVA's releases of tritium to the environment from Watts Bar operations have been and continue to be well within the NRC's regulatory limits and the terms of Watts Bar's Operating License. This has been the case before and subsequent to the implementation of the Tritium Project.

1 Indeed, TVA provides TDEC's Division of Radiological Health with a copy of each proposed WBN Operating License change, or License Amendment request, which it submits to the NRC. The NRC also provides that same department with a copy of each approved Operating License change at the time of approval. During the time in which it conducts an evaluation of a requested License Amendment, the NRC also notifies the Division of Radiological Health of the proposed issuance of the amendment and requests comments.

TestAmerica THE LEADER IN ENVtRONMENTAL TESTING Tennessee Valley Authority August 26, 2015 Mr. Chevalas Williams 1101 Market Street, Mail Stop PSC-i F-C Chattanooga, TN. 37402 Re: Tennessee Required Method Detection Limits (RDL)

Dear Mr. Williams,

Regarding your recently submitted jobs, the laboratory cannot meet the specified RDLs for Cyanide Acrolein, Acrylonitrile or 2,4,6-Trichlorophenol. The laboratory uses the method in 40 CFR136 is used to calculate MDLs. The laboratory utilizes instrumentation that meets or exceeds the analytical methods requirements. Any state specified RDL that is below our MDL is not generally achievable without modifying the root method or sacrificing the statistical significance of the result. I hope this addresses your concern. Please contact me if you have any questions or if you need additional information.

1. All flows in MGO.

2. Both units are operating in normal power generation mode.

3. Raw water additives will be used in the Intake Pumping Station and the Cooling Tower Basins.

4. For dual unit operation, two essential raw cooling water (EROW) pumps and six raw cooling water (RCW) pumps are operating with a total maximum flow rate of 75.042 MGD.

5. The flows through Ice Condenser chiller packages and various air coolers are doubled from Unit 1 Only Operation. The ERCW, and RCW discharge rates were rationed up by 21% to balance the flow diagram.
