REPORTS PREVIOUSLY SUBMITTED AS SPECIFIED IN THE WBN NATIONAL POLLUTANT DISC HARGE ELIMINATION SYSTEM (NPDES) PERIUIIT (continued)
E.
DMR Quality Assurance (QA) Laboratory Performance Evaluation Study 36 was completed by and submitted to Environmental Resource Associates, the TDEC, and the Environmental Protection Agency (EPA) prior to the August 26,2016 deadline. The cadmium, selenium, and total suspended solids value for DMR-QA Study 36 analyses performed and reported by our contract analytical laboratory - Test America were 'Not Acceptable'. After a careful investigation, the probable root cause was undetermined. Corrective action measures to ensure the current analysis process produces reliable and repeatable results were determined to be unnecessary as no reproducible issue was detected.
SPECIAL BIOLOGICAL IUIONITORING REPORTS A.
EPP Section 4.1.1, "Aquatic Monitoring"
- 1.
Routine semi-annual Whole Effluent Toxicity WET), a.k.a. chronic biotoxicity tests, were conducted on plant effluents and the appropriate reports were submitted as part of the DMR for Outfall Serial Numbers (OSNs) 101 and 113, in May and October 2016 as required by the NPDES permit. All TVA test results were valid for all sampling outfalls and dates and for both lC25 tests (P. promelas and C. dubia).
- 2.
A report on the "Biological Monitoring of the Tennessee River near the Watts Bar Nuclear Plant 2012" is not required in accordance with Part lll,Section I of the WBN NPDES Permit, but was a recommendation in the "Watts Bar Nuclear Plant Supplemental Condenser Cooling Water System Fish Monitoring Program, 2001" report to be consistent with other required annual reporting programs at Tennessee and Alabama nuclear plants. TVA determined in January 2013 that these reports, or an equivalent, would be submitted with the permit renewals versus the historical annual basis (last submitted December 29,2015 as a component of the NPDES permit renewal application).
- 3.
ln accordance with the provisions of Tennessee Code Annotated Section 69-7-301 et seq., the Water Resources lnformation Act, WBN submitted the Water Withdrawal Registration Form for Calendar Year (CY) 2016 to the TDEC prior to the February 15, 2017 deadline. Although federal agencies are not subject to laws and regulations promulgated by state governments unless Congress has clearly waived the federal government's sovereign immunity, in 2003 TVA voluntarily agreed as a matter of policy to provide the registration information in order to assist both TVA and TDEC in carrying out their water management responsibilities.

ENVIRONMENTALPROTECTIONPLANNONCOiiPLIANCES WBN received two Notice of Violations (NOVs) from February 2016 to February 2017.
A.
On November 8, 2016, the TDEC issued the WBN Compliance Evaluation lnspection (CEl) report and issued two NOVs:
- i. According to comments made by TVA personnel and the calibration report, Wafts Bar Nuclear Plant Dye Test Calibration for 0-FlT-27-98, January 26,2016, the flowmeter 0-FlT-27-98 may not maintain calibration between scheduled calibrations and should be calibrated on a more frequent basis. By failing to ensure that the flowmeter at OSN 101 maintains a tolerance of +1go1o, TVA WBN is not in compliance with Part llA.4 of its permit.
ii. By failing to repair the permanent temperature sensing system at OSN 101 in a timely manner, TVA WBN is not in compliance with Part A.4 of its permit and Note 4 in Part 1.
ln accordance with the NPDES permit, the following noncompliances were reported to the TDEC.
ln accordance with Part 1 of the NPDES permit, daily temperature monitoring at OSN 101 was conducted on January 01-22, February 12, May 13 through 31, June 1, 2, 26 through 30, July 3, 6, 9, 12,16,20,23,29, and 31, September 1 through 12 and the 29th, 2016 due to temperature monitoring equipment failure. WBN notified the TDEC on the applicable DMR cover letters.
On February 18, 2016 WBN reported to TDEC that WBN exceeded the benchmark monitoring requirement for iron at storm water monitoring outfall SW-g on January 15,2016.
Due to constraints on the OSN 101 flow meter, flows in excess of 80,000 gallons per minute (gpm) were calculated for the months of February 2016 through September 2016.
Due to meter fouling, flows were calculated at IMP 103 April 5 through 7, 11, 15, 20, 22 through 26, 28, 2016 and May 1, 3 through 16, 1 8, 22, 24 through 26, and 29 through 31,2016.
On June 18,2016, TVA notified the National Response CenterthatWBN had an oil sheen on the Cooling Tower Basin. Estimate of oil released into the cooling tower basin is less than one quart. Notifications were also made to Tennessee Emergency Management Agency (TEMA), the CDO, ODS, the National Response Center, the NRC (NRC event#520211, and the TDEC.
On July 11,2016 WBN reported to the TDEC in the June DMR cover letter that due to Turbine Building Station Sump (TBSS) pump failure on June 24,2016, the TBSS effluent was discharged on June 25 and 26, 2016 to the Yard Holding Pond via a storm water drain. This effluent was analyzed daily for OSN 101 parameters at the NPDES monitoring point and IMP 103 parameters at the discharge point. The results were included in the June DMR.

No oil sheen was visible in the Tennessee River from the bank above the diffuser pipes. Notifications were also made to TEMA the NRC (NRC event#52126), and the TDEC.
On August 09, 2016, TVA notified the National Response Center that Watts Bar Nuclear Plant had noted an oil sheen on the Cooling Tower Basin. No oil sheen was visible in the Tennessee River from the bank above the diffuser pipes. Notifications were also made to TEMA the NRC (NRC event#52163), and the TDEC.
On August 30, 2016, TVA reported a Notice of Unusual Event - Fire in a Main Bank Transformer (NRC event#52210). A fault occurred on the unit 2 "B" main bank transformer resulting in an oil fire and the loss of approximately 15,000 gallons of oil to the site drainage system and ponds. The main turbine tripped resulting in a reactor trip. The fire began at2110 EDT and was reported out at2228. Unit 1 continued operation. Notifications were also made to the DHS SWo, FEMA ops Center, DHS NICC, FEMA NationalWatch Center (E-mail) and Nuclear SSA, the NRC, and the TDEC.
WBN notified the TDEC on the September 2016 DMR cover letter of the Mussel Relocation Zone (MRZ) average calculation for September 1 through 18 and27 through 30, 2016 due to a failure in the temperature monitoring equipment failure.
The NRC event#52400 involved the release of a GE BETZ Chemical Flogard*
MS6237 (ratio of materials 2O-4Oo/o for both Zinc Chloride and Phosphoric Acid) on November 29,2016. The release of approximately 525 gallons was reported in the National Response Center report 1 165106 (total volume of the container was 2,500 gallons). From the total spilled and the percentage estimations from GE BETZ, the material exceeded the Zinc chloride Reportable Quantity (Ra) of 1,000 pounds.
TVA demonstrated that Phosphoric Acid did not exceed its RQ of 5,000 pounds. A notification was given to the National Response Center, Rhea County LEPC, Tennessee Emergency Management Agency, and the TDEC.
