On October 2, 16, 23, and 30, the weekly total residual chlorine (TRC) sample results tested below the POL of 0.05 mg/I and were therefore reported as zero. Chlorine is analyzed by the Westinghouse onsite chemical laboratory by SM 4500-CL G-2011.

On October 9, the monthly E. coli result tested below the POL of 1 MPN/100 ml and was therefore reported as zero. E. coli is analyzed by Access Analytical according to SM 9223 B-2004.

If you have any questions regarding the enclosed reports, please contact Ms. Cynthia Logsdon, Environment Health & Safety, at (803) 647-3171.

Dear Sirs and Madams:

RE:

NPDES Permit #SC0001848 Westinghouse Electric Company LLC Nuclear Fuel Columbia Fuel Site 5801 Bluff Road Hopkins, South Carolina 29061 USA Direct tel:

803-647-1000 Direct fax:

803-695-3964 e-mail: logsdocj@westinghouse.com Our ref:

L TR-RAC-20-50 May 26, 2020 The enclosed Discharge Monitoring Report is submitted to fulfill the NPDES summary reporting requirements. The 2020 Toxicity Report is also attached.

This monthly summary covers the monitoring period from April 1, 2020, through April 30, 2020.

All received sample results were within NPDES permit limits.

On April 8, the monthly E. coli result tested below the POL of 1 MPN/100 ml and was, therefore, reported as zero. E. coli is analyzed by Access Analytical according to SM 9223 B-2004.

One excursion of the BOD requirement occurred the week of April 22. Per GEL Laboratories via email correspondence on April 28:

"Results for this analysis have been compromised due to an isolated failure of the Deionized Water System used in the analytical processes. Use of the data may not reflect the true concentrations normally experienced in the sample. GEL is purchasing DI water for this lab until we can rectify the issue. Based on the LCS results, this data should not be used for regulatory reporting. Results are biased low."

Therefore, the weekly BOD result for April 22 was not included in the daily average or daily maximum reported, and one excursion was marked on the DMR. The issue was entered into the Westinghouse Corrective Action Program #2020-5328.

On April 29, Westinghouse notified Sonya Johnson and Lucas Berresford of the following river discharge piping maintenance issue. Notification is included in this DMR as required per Part II Section L.6 of NPDES Permit #SC0001848:

At approximately 3:35 pm on 4/28/20, Environment, Health and Safety (EH&S) personnel were informed of a leak in the treated wastewater discharge line from the Westinghouse plant to the Congaree River. Maintenance activities to repair a culvert on the dirt road, about a mile from the river, inadvertently impacted the line, and the leak was discovered right away. River discharges were stopped and locked out until maintenance repairs were completed the same day. The issue was entered into the Westinghouse Corrective Action Program# 2020-5267.

L TR-RAC-20-55 June 25, 2020 The enclosed Discharge Monitoring Report is submitted to fulfill the NPDES summary reporting requirements. This monthly summary covers the monitoring period from May 1, 2020, through May 31, 2020. All received sample results were within NPDES permit limits.

On May 13, the monthly E. coli result tested below the PQL of 1 MPN/100 ml and was, therefore, reported as zero. E. coli is analyzed by Access Analytical according to SM 9223 B-2004.

On May 13, Ammonia-N was sampled by Westinghouse according to standard method 4500-NH3-D (selective electrode method) and by PACE according to EPA method 350.1 (gas diffusion).

On May 20 and 27, the weekly total residual chlorine (TRC) sample result tested below the PQL of 0.05 mg/I and was, therefore, reported as zero. Chlorine is analyzed by the Westinghouse onsite chemical laboratory by SM 4500-CL G-2011.

As communicated to you on June 12, 2020, Westinghouse impacted an 8-inch PVC Contaminated Wastewater (CWW) pipe during implementation of NPDES construction permit IW021063 as part of our efforts to close the East Lagoon. This pipe transports emergency cooling water, cooling tower blowdown, dehumidification condensate, and laboratory and floor drain wastewaters to the Contaminated Sump for treatment. During the construction activities, an excavation (about 8' x 4' and 6' deep) was completed on June 10, and a metal plate was placed over the area. When the plate was removed the morning of June 12, about 50-100 gallons of water was identified in the excavated area. Sample results of the water were 5.35E-07 uCi/ml gross alpha and 5.68E-07 uCi/ml gross beta, as analyzed by our onsite Health Physics Laboratory, and 0.03 ppm U, as analyzed by our onsite Chemical Laboratory. These results are below our internal process control limits for discharge to the Congaree River. Inputs into the line were stopped, the water was pumped out of the excavated area and repairs were completed the same day. The issue was entered into our Corrective Action Program #2020-7135. Implementation of the construction permit was successfully completed and inspected by DHEC personnel on June 19.

DMR Comments: Revision 11/18/2020: Ammonia data updated to include September 30 samples. TSS average data updated to include September 30 samples. These results were not included during original submission due to lab report error, discovered during preparation of October 2020 DMR.

The plant discharged 29 of 30 days during September 2020. On September 2, the weekly total residual chlorine (TRC) sample result tested below the PQL of 0.05 mg/l and was therefore reported as zero. Chlorine is analyzed by the Westinghouse onsite chemical laboratory by SM 4500-CL G-2011. On September 10, the monthly e. coli sample result tested below the PQL of 1 MPN/100 ml and was therefore reported as zero. E. coli is analyzed by Access Analytical according to SM 9223 B-2004.

At approximately 02:00 on 9/27/20, a pump seal in our wastewater treatment area failed, spraying a fine mist onto the rocks just outside the containment pad. The estimated quantity was less than a pint of Conversion area wastewater consisting of ammonium fluoride and uranium. The uranium concentration in the tank was 90.62 ppm U. An approximate 2 foot by 2 foot area outside the containment dike was cleaned up. No solution impacted the ground or storm drains. The issue was entered into our Corrective Action Program # 2020-10832 and reported to the Midlands EQC on 9/28/20.

A routine process sample had been pulled at 04:00. The estimated quantity spilled outside of the building was 350 gallons of water and lime, containing 27 ppm ammonia, <10 ppm fluoride, and 0.09 ppm uranium, with a pH of 11.98. This spill did not contain a reportable quantity (RQ) of any chemical. No material from the spill was discharged from the site. Lime settled in the storm water ditch system at A Valve, about 800 feet from the sites single discharge point for storm water, C Valve. The impacted area was less than 10 x 4 and the settled material was removed by portable pump with collection in 250-gallon plastic totes for additional sampling and proper disposal. Sample results were provided to the Midlands EQC.

Aquatic life in the ditch continues to be active. The issue was entered into our Corrective Action Program as # 2020-11160.
