- THE STATE OF SOUTH CAROLINA BEFORE THE DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL IN RE: DOMlNION ENERGY SC, INC VC SUMMER NUCLEAR STATION OFF-SITE WATER SYSTEM FAIRFIELD COUNTY CONSENT ORDER 22-024*1 The South Carolina Department of Health and Environmental Control (Department) and Dominion Energy SC, Inc. (Dominion) have agreed to the issuance of this Consent Order to include the following Findings of Fact and Conclusions of Law.
FINDINGS OF FACT I.
Dominion owns and is responsible for the proper operation and maintenance of the VC Summer Nuclear Station Off-site Water System (VC Summer WWTF) located at 400 Brabham Boulevard, in Fairfield County, South Carolina. VC Summer WWTF serves Dominion's VC Summer Nuclear Station.
- 2.
The Department issued the National Pollutant Discharge Elimination System (NPDES)
Permit SCG646072, authorizing V C Summer WWTF to discharge filter backwash to the Monticello Reservoir in accordance with effluent limitations, monitoring requirements and other permit conditions contained therein. The NPDES Permit became effective November 2, 2017 and has an expiration date of December 30, 2020. The NPDES Permit is administratively continued due to an application for renewal of the permit being submitted at least one hundred eighty (180) days before the expiration of the permit.
1
- 3.
On November 9, 2021, Dominion emailed Department staff regarding operations at VC Summer WWTF. Dominion explained the laboratory servicing VC Summer WWTF has not been certified to perform total residual chlorine (TRC) since June 2018. Dominion explained the laboratory is in the process of being recertified for TRC, and until recertified, Dominion will use a certified vendor laboratory for TRC analysis.
- 4.
On November 18, 2021, Department staff issued a Notice of Violation (NOV) to Dominion for failure to use a South Carolina state certified laboratory for sampling and analysis of TRC for the June 2018 through September 2019, December 2019 through March 2020, October 2020, December 2020, February 2021, June 2021, and July 2021 monthly monitoring periods. The certified copy was delivered on November 22, 2021. No response was required because Dominion submitted an explanation of the violation November 9, 2021.
- 5.
On January 6, 2022, Department staff issued a Notice of Alleged Violation. and Enforcement Conference (NOA V /EC) to Dominion via first class and certified mail. The NOA V /EC was delivered January 10, 2022.
- 6.
On January 24, 2022, Department staff held an enforcement conference with Dominion.
Dominion explained the state certification for TRC was purposefully terminated, but the termination of the certification was not communicated with laboratory personnel for Dominion. Dominion further explained laboratory staff were regularly performing quality control testing while in violation and. since identification of the violations, Dominion has been using a South Carolina state certified contract laboratory for TRC measurements. The issuance of a Consent Order containing a civil penalty was discussed.

us A grab compliance pH sample of 8.8 su was obtained from Outfall 014 and a backup aliquot had the same results from the December 3, 2021 NPDES sampling event.
Because the sample results were not i ndicative of the discha r ged str eam, Chemistry personnel suspected the initial and backup samples were contaminated. Upon investigation, it was determined that the telescoping sample cup was used to check the water quality at Outfall 006B during cleanup efforts for the November 16, 20 21 transformer oil spill.
VCS beli eves the initial pH sample result is due to cross contamination introduced b y using the same telescoping sample cup to obtain the monthly sample for Out fall 014.
A new telescoping sample cup was used an hour later to obt ain another sample and another aliquot using what was analyzed using another pH meter.
The first sample with the new apparatus was 8.36 su and the second aliquot result was 8. 39 su.
This occurrence has been documented in the station ' s corrective action program (CR 03611).

INSTANTA Monthly NEOUS IN INSTANTA NEOUS Monthly IN TSS - Analysis of a grab sample of 06B on 3/7 yielded a TSS value of 32. 6 ppm. Delays in receiving and reviewing the vendor data resulted in a missed opportunity for additional samples during the month, yielding an exceedance of the monthly average limit of 30mg/l. This higher than normal TSS value is belie ved to be an anomaly as results from the previous 4 years do not exceed 15 ppm. In addition, the RPD between the sample/duplicate or matrix spike/spike duplicate was not within control limits due to matrix interference.

DISCHARGE MONITORING REPORT (DMR)

1/31 /2022 DMR Instructions: OUTFALL OBA 1-TOTAL RESIDUAL CHLORIINE (TRC) LIMITS FOR ALL WATER CLASSIFICAT I ONS (FW,
or SFH).
DMR Comments : DESC VCS is skeptical of the TRC 0. 05 mg/L result for the following reasons :
Prior to the discha r ge sample, VCS personnel obtained multiple samples from both retent i on basins and obtained results that were less than 0. 05 mg/L (nondetectable).
VCS ' s reverse osmosis system backwash process only contains raw water, which isn ' t treated with chlorine.
Throughout the Offsite Water System operating history, TRC has never been detected at the outfall.
There is no significant source of chlorine to the retention basins that could result in TRC level of 0. 05 mg/L.
The occurrence of TRC results above the permitted limits has been entered into the station's corrective action program (CR1192303) and is under evaluati on to determine the source and the validity of TRC 0.05 mg/L result.
DMR Value Comments:
Total Residual Chlorine, Effluent Gross (1), Limit : 0. 011 Monthly Average, Reported Value: 0.05, Comment : DESC is investigating the source of TRC.
The results are suspect because TRC was never detected at the discharge previous ly.
See General Report Comments for full details.
