Tennessee Valley Authority - Sequoyah Nuclear Plant - Tennessee Storm Water Multi-Sector General Permit for Industrial Activities Permit No. TNRO50000 Sector 0 Exceedance of the Monitoring Cut-Off Concentration 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 November 15, 2002. The storm water analytical monitoring results were received on December 5, 2002. As stated in Table 0-1, Monitoring Requirements for Steam Electric Power Generating Facilities, the cut-off concentration for total recoverable iron is 5.0 mg/L. The analytical monitoring results for Storm Water Outfall No. 2 showed a total recoverable iron concentration of 6.2 mg/L.
Likely Causes of the Exceedance:
Likely causes of the exceedance of the cut-off concentration for total recoverable iron are:
(1) Background iron concentrations in the soil in the area of Storm Water Outfall No. 2 and/or (2) Increased industrial activity in the area surrounding Storm Water Outfall No. 2 due to the Steam Generator Replacement Project scheduled to be completed June 2003.
