Subject:
Approval of Modification of Biocide/Corrosion Treatment Plan (B/CTP)
NPDES Permit No. TN0020168 TVA - Watts Bar Nuclear Plant Spring City, Rhea County, Tennessee
Dear Ms. Phillips:
First, on behalf of the Division of Water Pollution Control (the "Division") we extend our thanks to you, Mr. Hutchinson, and Mr. Bledsoe for meeting with us on, April 24, 2007, in the TVA Chattanooga Missionary Ridge Building to discuss changes to the Biocide/Corrosion Treatment Plan (B/CTP), and the renewal application for Watts Bar Nuclear Plant, NPDES permit number TN0020168.
On December 21, 2006, and on February 21, 2007, TVA requested by letter to amend the current B/CTP to change processes and chemicals as follows: (1) process change for continuous use of oxidizing biocides, (2) the use of sodium hypochlorite as an alternative to Nalco H-901 G, an oxidizing biocide, and (3) the replacement of dispersant PCL-401 with 73200; also an anionic copolymer used to facilitate iron corrosion inhibition. The Division requested additional information and thus the meeting was planned to discuss these changes.
TVA presented additional information by way of verbal and written description of activities and findings within the plant components and physical data, as requested by the Division, to verify that the continuous application of oxidizing biocides does not violate current permit limitations set at 0.10 mg/L,Total Residual Chlorine (TRC). The Division and TVA did agree to increase the (DMR) reporting frequency to "Daily", which will be reflected in the new NPDES permit when public noticed. As such, this letter serves to approve all changes to process [applications]
and chemicals in the Watts Bar Nuclear Plant, B/CTP as requested in TVA's letters where referenced above. Further discussion of the application for new NPDES permit will be addressed in a separate letter.
It Ms. lerri L. Phillips TVA - Watts Bar Nuclear Plant Page 2 of 2 If you have questions, please contact the Division at the Chattanooga Environmental Field Office at 1-888-891-TDEC; or, at this office, please contact Ms. Pamala Myers at (615) 532-0654 or by E-mail at Pamala.Myersstate.
