III. SPECIAL BIOLOGICAL MONITORING REPORTS A. EPP Section4.l.l, "Aquatic Monitoring"

1. Routine semi-annualWhole 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 June and October 2017 as required by the NPDES permit. All TVA test results were valid for a!! 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 WaterWithdrawal Registration Form for Calendar Year (CY) 2017 to the TDEC prior to the February 15,2018 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 bolh TVA and TDEC in carrying out their water management responsibilities.

4. On July 27,2017, TVA submitted 316(b) Compliance Study Reports as required under 40 CFR S 122.21 paragraphs (rX2), (rX4), through (r)(8) to the TDEC.

Watts Bar.

IV. ENVIRONMENTALPROTECTIONPLANNONCOMPLIANCES WBN received zero Notice of Violations (NOVs) from February 2017 to February 2018.

ln accordance with the NPDES permit, the following noncompliances were reported to the TDEC.

A. WBN did not record valid temperature readings at outfall 101 from November 23, 2017 through November 25, 2017. The NPDES permit requires the station to monitor for temperature daily at outfall 101. Temperature element 0-TE-27-99 is used to monitor temperature continuously at outfall 101. There is also a battery powered backup monitor that can monitor temperature if needed in order to comply with the NPDES permit. From November 23, 2017 through November 25,2017,0-TE-27-99 was not recording valid temperature readings. At the same time, the battery power backup monitor lost power. Therefore, no temperature data was recorded for that period. Conective Actions: (1) Enhance site procedures; (2) Verify operation of battery powered backup monitor daily whenever 0-TE-27-99 is not recoding valid temperature readings.

V. CHANGES iiADE TO APPLICABLE STATE AND FEDERAL PERMITS AND CERTIF!CATIONS A. NPDES Permit Number TN 0020168

'1. ln accordance with 40 CFR 122.22, TVA updated the NPDES signatory authority authorizing the positions of WBN Plant Manager and the Chemistry and Environmental Senior Manager as the duly authorized persons for signing reports required under the permit as wel! as other WBN compliance reports.

2. TVA submitted a request for a waiver of the Section ($ 122.21 (r)(9) through (13) of the $ 316(b) rule on September 5, 2017 . This request was based largely on the flow reductions associated with the facility's closed-cycle recirculating cooling water system, as augmented by a supplemental cooling water system, and upon the unique use of two distinct waterbodies as cooling water sources.

B. Air Permits Number 463822

1. ln accordance with 1200-03-09-.02(11)(b)21(i) of the Tennessee Air Pollution Control Regulations, TVA updated the Air signatory authority authorizing the position of WBN Plant Manager as the duly authorized persons for signing reports required under the permit as well as otherWBN compliance reports.

2. TVA applied for the Air permit to include the DG-8 Construction Permit for a TSOB Building Replacement Emergency Generator Diesel Engine in March, 2016. The TDEC finalized the approval in March 2017.
