-SEQUOYAH NUCLEAR PLANT -TENNESSEE STORM WATER MULTI-SECTOR GENERAL PERMIT FOR INDUSTRIAL ACTIVITIES PERMIT NO.TNR050015 SECTOR 0 EXCEEDANCE OF THE BENCHMARK MONITORING REQUIREMENT.

Please find enclosed the thirty day notification and the lab analysis for the exceedance of the benchmark monitoring requirement for total recoverable iron for Storm Water Outfall Nos. 1, 2, 15, and 17.Description of Event Tennessee Storm Water Multi-Sector General Permit for Industrial Activities Sector 0 requires annual monitoring of total recoverable iron. Sequoyah Nuclear Plant sampled for total recoverable iron on March 2, 2010 and March 11,2010. The storm water analytical monitoring results were received on March 8, 2010 and March 19, 2010. The analytical monitoring results for Storm Water Outfalls Nos. 1, 2, 15 and 17 exceeded the benchmark monitoring requirement for total recoverable iron as stated in Table 0-2, Benchmark Monitoring Requirements for Steam Electric Power Generating Facilities.

Storm Water Outfall No. 2 was sampled for total recoverable iron on March 2, 2010 and results were received on March 8, 2010. The analytical monitoring result for Storm Water Outfall No. 2 was6.3mg/L.

The backup sample for Storm Water Outfall No. 2 was sent for analysis on March 8, 2010 and results were received on March 10, 2010. The backup analytical monitoring result for Storm Water Outfall No. 2 was 4.3mg/L. Since the backup sample result was below the benchmark of 5.Omg/L, SQN had the original and the backup samples reanalyzed.

The original sample was reanalyzed and the iron results were 5.5mg/L and 5.2mg/L. The backup sample was reanalyzed and the iron results were 5.2mg/L and 5.2mg/L. The average of the six analytical monitoring results for Storm Water Outfall No. 2 was 5.3mg/L. (See Table 1)Storm Water Outfall Nos. 1, 15, and 17 were sampled for total recoverable iron on March 11, 2010 and results were received on March 19, 2010. The analytical monitoring results for Storm Water Outfall Nos. 1, 15, and 17 were 12.Omg/L, 7.4mg/L, and 6.2mg/L respectively.

Backup samples for Storm Water Outfall Nos. 1, 15, and 17 were sent for analysis on March 22, 2010 and results were received on March 26, 2010. The backup analytical monitoring results for Storm Water Outfall Nos. 1, 15, and 17 were 11 .Omg/L, 7.6mg/L, and 6.9mg/L respectively.

The average analytical monitoring results for Storm Water Outfall Nos. 1, 15, and 17 were 11.5rmg/L, 7.5mg/L, and 6.6mg/L respectively. (See Table 1)

Likely Cause of the Exceedance(s)

The likely cause of the. exceedances(s) of the benchmark monitoring requirement for total recoverable iron is elevated background iron concentration in the soil around the storm water outfalls (based on historical sampling) and the need for more effective best management practices (BMPs). Sequoyah is examining the use of more effective filtration methods at these outfalls.If you have any questions or need additional information, please contact Ann Hurt at (423) 843-6714 or Stephanie Howard at (423) 843-6700 of Sequoyah's Environmental staff.Sincerely, Christopher R.
