SUBJECT:

Beaver Valley Nuclear Power Plant 200 State Rt. 3016, P.O. Box4 Shippingport, PA 15077 Beaver Valley Nuclear Power Plant Discharge Monitoring Report (NPDES) Permit No. PA0025615 Enclosed are the September 2025 NPDES Discharge Monitoring Report (DMR),

Chemical Additives Usage Forms, Daily Effluent Monitoring Forms, Cooling Water Intake Monitoring Forms, Non-Compliance Reporting Form, Q3 2025 DMR and Q3 2025 Daily Effluent Forms.

A review of the data indicates that no Part A NP DES effluent limits were exceeded during the monitoring period. Outfall 001 requires continuous flow monitoring with a daily reported value, however, the flow meter was out of service on 9/1/2025 preventing a flow value from being obtained. A non-compliance reporting form for sample collection less frequent than required is included with this submission.

Should you have any questions regarding the enclosed documents, please direct them to Jim Harvey, at 724-682-7358.

Sincerely,

'Robert 17. KristoJJhet ONtt
