INTRODUCTION This 2024, Environmental Operating Report for the North Anna Power Station is submitted by Virginia Electric and Power Company, as required under Section 5.4.1 of Appendix B,
Environmental Protection Plan (EPP).
The objective of the EPP is to verify that the North Anna Power Station is operated in an environmentally acceptable manner, consistent with NRC and other
- federal, state, and local requirements as well as to keep the NRC informed of any environmental effects of facility construction or operation.
During
- 2024, there were no significant adverse environmental impacts that occurred as a result of the operation of North Anna Power Station, Units 1 and 2.
Aquatic issues are addressed in the licensee's VPDES permit (number VA 0052451) issued by the Virginia State Water Control Board.
The VPDES permitting program is administered by the Department of Environmental Quality and the NRC relies on this agency for regulation of matters involving water quality and aquatic biota.
Listed below are the summaries and analyses required by Subsection 4.2 of the EPP.
PLANT DESIGN AND OPERATION (SECTION 3.1)
A review of all changes in station design or operation, tests and experiments failed to reveal any potentially, significant, unreviewed, environmental issues.
EROSION CONTROL INSPECTION -
SITE (SECTION 4.2.2.1)
Performance of Periodic Test Procedure, 1-PT-9.3, Erosion Control Inspection-Station Site, and 0-PT-75.12: Visual Inspection of the Service Water Reservoir Dike Crest and Toe, were completed by the Civil/Design Engineering Department. One (1) area of concern that needed corrective action was identified during the performance of 1-PT-9.3. There were three (3) areas of concern identified during the performance of 0-PT-75.12.
The one (1) area identified in 1-PT-9.3 was as follows:
Erosion was found located on the slope between the Fire Pump House and the main access road. Erosion appeared to be due to water Page 2 of 4
runoff from the main road over a period of time.
The three (3) issues that were identified during the performance of 0-PT-75.12 were as follows:
Minor potholes were found along the access road that needed to be fixed.
Ground hog holes were found on the reservoir embankment and on the diversionary dike that needed to be filled in.
Minor brush and vegetation removal was needed on the service water reservoir embankment.
All issues identified were entered into the station's corrective action system and corrective action assignments have been assigned. There were no issues observed that adversely impacted site erosion control measures, storm water run-off, or station operation.
There were no construction activities in 2024 at North Anna that were required to be controlled by a VAR-10 permit.
EROSI'ON AND SEDI'MENT CONTROL PROGRAM CORR:CDOR RI'GHTS-OF-WAY SECT:CON 4.2.2.2)
During 2024, all transmission line rights-of-way were patrolled to coordinate brush and tree work needed for maintenance of the lines. This work involved the following:
North Anna-to-Gordonsville (Louisa-South Anna) corridor: A contract crew performed all brush and tree work for reliability as needed. Herbicide work began on 07/08/2024 and was completed on 07/18/2024. No significant erosion was observed.
North Anna-to-Morrisville corridor: The patrol revealed that there was no significant tree or brush work needed, and no significant erosion was observed.
North Anna to Ladysmith corridor: A contract crew performed all brush and tree work for reliability as needed. Herbicide work began on 07/11/2024 and was completed on 07/15/2024. No significant erosion was observed.
North Anna to Midlothian corridor: A contract crew performed all brush and tree work for reliability as needed. Herbicide work began on 06/17/2024 and was completed on 08/14/2024. No significant erosion was observed.

During all of the above-noted patrols and follow-up observations, no abnormal erosion conditions were observed on any of the above corridors associated with transmission line construction, modification, maintenance activities or the use of herbicides during 2024.
NON-COMPLIANCE (SECTION 5.4.1)
There were no non-compliances with the Environmental Protection Plan during 2024.
NON-ROUTINE REPORTS (SECTION 5.4.2)
