Washington, D.C. 20555-0001 Donald C. Cook Nuclear Plant Units 1 and 2 NOTIFICATION AND RETRACTION FOR POTENTIAL UNDERGROUND STORAGE TANK LEAK OF DIESEL FUEL OIL On August 21, 2014, Indiana Michigan Power Company (I&M), the licensee for Donald C. Cook Nuclear Plant (CNP) Units 1 and 2, made a telephone notification of a potential underground storage tank leak of diesel fuel oil and subsequent CERCLA (Comprehensive Environmental Response, Compensation, and Liability Act of 1980) Reportable Quantity exceedance of xylene and naphthalene at our facility to the Michigan Department of Environmental Quality, Local Emergency Planning Coordinator, and the National Response Center. In a letter dated August 26, 2014, I&M retracted this notification to all the agencies listed above. The letter of retraction is provided as an enclosure to this letter, in accordance with CNP's Nonradiological Environmental Protection Plan, Section 5.4.2.

I&M made this notification as a precautionary measure. The data originally indicated approximately 8,700 gallons of diesel fuel oil was lost from an underground storage tank on site. I&M has since determined the indication of sudden loss of underground storage tank inventory was due to an errant tank level gauge reading, which has since been repaired. No product was lost from the storage tank. It was not necessary to notify these agencies, therefore, I&M retracts the notification.

This letter contains no new commitments. Should you have any questions, please contact Jon H. Harner, Environmental Manager, at (269) 465-5901, extension 2102.

Sincerely, A sca,(-941ý.o Michael K. Scarpello Regulatory Affairs Manager

Dear Captain Adams:

On August 21, 2014, we reported a potential underground storage tank leak of diesel fuel oil and a corresponding CERCLA [Comprehensive Environmental Response, Compensation, and Liability Act of 1980] Reportable Quantity (RQ) exceedence of xylene and napthalene at our facility to the National Response Center (Ms. Rawls), the Local Emergency Planning Coordinator (Operator 752), and the Michigan Department of Natural Resources and Environment (Mr. Hopkins -

11606). We did this as a precautionary measure due to an emergency response procedure requiring an immediate notification for potential loss of diesel fuel oil to the groundwaters of the state, and the quantity of xylene and naphthalene leaked triggering CERCLA/EPCRA [Emergency Planning and Community Right-to-Know Act] notification. We have since determined that the indication of the sudden loss of underground storage tank inventory was due to a malfunctioning tank level gauge and that no product was lost from the storage tank. We are retracting the notification to all the agencies listed above.

Our data originally indicated that approximately 8,700 gallons of diesel fuel oil was lost from an underground storage tank on the site. We have determined that the tank level gauge had malfunctioned due to a blocked vent on the tank.

No product was lost, the vent has been repaired and the level of the tank has returned to its original level. It was not necessary to notify the SERC/LEPC

[State Emergency Response Commission/Local Emergency Planning Committee], or the National Response Center.

Please contact me at (269) 465-5901 extension 2102 if you have any questions regarding this information.

Sincerely, Jon H. Harner Environmental Manager
