Dear Mr. Alexander:

TENNESSEE VALLEY AUTHORITY (TVA) -SEQUOYAH NUCLEAR PLANT (SQN) - NPDES PERMIT NO. TN0026450 - REQUEST FOR BIOCIDE/CORROSION TREATMENT PLAN (B/CTP)

REVISION APPROVAL Sequoyah Nuclear Plant plans to add Flogard MS6237 to our Biocide/Corrosion Treatment Plan.

This chemical will replace Flogard MS6236 for corrosion prevention. The SDS for MS6237 is attached. As shown in the SDS, the active ingredients are phosphoric acid, zinc chloride, and zinc bis(dihydrogen phosphate). MS6237 will be applied at a maximum feed rate of 2.4 ppm. The maximum effluent concentrations will be 0.2 ppm phosphate and 0.2 ppm zinc.

• The site would like to begin using the new chemical in mid-December, therefore we are requesting written approval by December 9, 2016. If you have questions, or need additional information, please contact Millicent Garland at 423-843-6714, of Sequoyah's Environmental staff.

I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate 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.
