Subject:
McGuire Nuclear Station Docket Nos. 50-369 and 50-370 Standby Nuclear Service Water Pond Dam Audit (TAC Nos. MA3823 and MA3824)
On October 14, 1998, an audit was conducted at McGuire Nuclear Station for the Category 1 Standby Nuclear Service Water Pond Dam by the Federal Energy Regulatory Commission (FERC).
The FERC inspector was accompt.nied by a Nuclear Regulatory Commission inspector from Headquarters. The conclusion of the audit was that there were no conditions observed-that would indicate an immediate or adverse threat to the safety and permanence of the project structures.
However, there were.two items identified that required followup corrective action.
The NRC received and evaluated the final report from the FERC. The NRC requested that Duke Energy provide a written response by September 30, 1999.
Please find attached Duke Energy's response.
~Any questions concerning this matter should be directed to Kay Crane, McGuire Regulatory Compliance at (704) 875-4306.
Very truly yours, lY H. B. Barron, Vice President j

Response to Standby Nuclear Service Water Pond Dam Audit Items i
Several colonies of fire ants were found on the dam.
These l
pests can dig burrows as deep as 4 feet and lateral foraging tunnels as long as 8 feet.

Response
The Cowens Ford Maintenance crew was dispatched and the fire ants were destroyed.
The rutted areas of the dam were repaired.
