SUBJECT:

Beaver Valley Power Station 200 State Rt. 3016, P.O. Box 4 Shippingport, PA 15077 Beaver Valley Power Station Discharge Monitoring Report (NPDES) Permit No. PA0025615 Enclosed are the November 2024 NPDES Discharge Monitoring Report (DMR), Chemical Additives Usage Forms, Daily Effluent Monitoring Forms, Cooling Water Intake Monitoring Forms, Supplemental Laboratory Accreditation Form and Non-Compliance Reporting Form in accordance with the requirements set forth in the site NPDES permit. A review of the data indicates that total mercury sampling on 11/2/2024 for Outfall 001 yielded a detection slightly above the method 245.1 RL of 0.2 ug/L. Beaver Valley Power Station has no on-site sources of mercury as confirmed by the NPDES permit required TRE study conducted in 2022 leading to the conclusion that there was likely error during lab analysis of this sample. Re-analysis of the detect sample was requested of Eurofins, the permittee's contract lab, and the second sample analysis yielded a non-detect result of< 0.2 ug/L - the method 245.1 RL and effective permit limit for the applicable outfall. However, the exceedance was not discovered until the sample was r Jtside the 28-day hold limit for the analytical method. Please see thP r--:on-Compliance 1-<eporting Form and attachments for additional information. Should you have any questions regarding the enclosed documents, please direct them to James Harvey, at 724-682-7358. Sincerely, t Roi rt J. Knstophel,Dec 19, 2024 1 3G EST Robert Kristophel General Plant Manager

A TRE study conducted in 2022 in accordance with NPDES permit requirements verified there are no contributions of mercury from any plant process to the permit outfalls and river background sampling also yielded no mercury detections. The 11/2/2024 sample collected at Outfall 001 yielded an initial analytical result of 0.26 ug/L which also yields a monthly average of< 0.23 ug/L. The permittee's contract lab, Eurofins, was supposed to have the permit limits flagged in their system to automatically trigger notification and re-analysis of a sample exceeding any permit limit, however, the limit flag was discovered to be set incorrectly resulting in no notification being generated. The exceedance was not discovered by BVPS personnel until the sample exceeded the 28-day hold time for the analytical method. Sample re-analysis was immediately requested which yielded a non-detect result< 0.2 ug/L, and, though this result is outside of the hold time, BVPS believes it verifies lab error with the initial analysis. Communication with Eurofins has ensured that the mercury limit flags are now set correctly in their system and the site's mercury samples will receive higher levels of scrutiny in the future to ensure analysis is correct. The laboratory analysis sheet indicating both results is attached.
