TNR050000 SECTOR 0 EXCEEDANCE OF THE MONITORING CUT-OFF CONCENTRATION.

2 Please find enclosed'the thirty day notification and the lab analysis for the exceedance of the monitoring cut-off concentration for total recoverable iron for Storm Water Outfall Nos. 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 January 10,2009 and February 2, 2009. The storm water analytical monitoring results were received on January 22, 2009 and February 10, 2009. The cut-off concentration for total recoverable iron is 5.0 mg/L, as stated in Table 0-1, Monitoring Requirements for Steam Electric Power Generating Facilities. The analytical monitoring results

• for Storm Water Outfalls Nos. 2, 15 and 17 were 11mg/L, 6.9mg/L, and 5.7mg/L respectively.

See table below:

cQ O/

Likely Causes of the Exceedance The likely causes of the exceedances of the cut-off concentration for total recoverable iron are

• elevated background iron concentration in the soil around the storm water outfalls (based on historical sampling) and the need for additional best management practices (BMPs).

Sequoyah will enhance our BMPs such as adding more rip rap and gravel in the area to ensure that soil is adequately covered.
