Dear Ms. Myers:

SEQUOYAH NUCLEAR PLANT (SQN) - NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) PERMIT NO. TN0026450 - ADDITION OF MSW-101 TO THE BIOCIDE/CORROSION TREATMENT PLAN Sequoyah Nuclear Plant (SQN) plans to add MSW-101 to our Biocide/Corrosion Treatment Plan. This addition is considered a minor change by SQN due to the fact that MSW-101 is similar to the already approved PCL-222. All relevant information (frequency of discharge, active ingredients, discharge concentration, maximum daily usage, MSDS, product bulletin, etc.) on MSW-101 is attached. SQN considers this a courtesy notification which does not require pre-approval and will submit this information again in the 2007 annual report.

If you need additional information or have comments or questions, please contact Ann Hurt (423-843-6714) or myself (423-843-6700).

I certify under penalty of law that this document and all of its attachments were prepared under my direction or my supervisor in accordance with a system designed to assure qualified personnel properly gathered and evaluated the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.

Sincerely, 0ftLL W

Maximum Daily Usage provides an indication of loading in the receiving stream. It is the maximum amount of active ingredients for the worst case scenario of flow and feed concentration being proposed plus a 10% margin of error. SQN will request a change to this plan should an increase in maximum daily usage becomes necessary for the continued safe operation of the plant.

3.

MSW-101 is a blend of orthophosphate and hexametaphospliate. MSW-101 is injected into the RCW system continuously, except during periods of other chemical injection due to common injection lines. MSW-101 is injected into the ERCW Train A & B system only during warmi weather months. During cool weather months PCL-401 is injected.
