Tennessee Valley Authority, Post Office Box 2000, Soddy Daisy, Tennessee 37384-2000 February 25, 2011 Chattanooga Environmental Field Office Division of Water Pollution Control State Office Building, Suite 550 540 McCallie Avenue Chattanooga, Tennessee 37402 TENNESSEE VALLEY AUTHORITY - SEQUOYAH NUCLEAR PLANT - TENNESSEE STORM WATER MULTI-SECTOR GENERAL PERMIT FOR INDUSTRIAL ACTIVITIES PERMIT NO.
TNRO50015 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 Numbers 1, 2, and 9.
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 15, 2011 and January 16, 2011. The storm water analytical monitoring results were received on February 4, 2011. The analytical monitoring results for Storm Water Outfalls Nos. 1, 2, and 9 exceeded the benchmark monitoring requirement for total recoverable iron as stated in Table 0-2, Benchmark Monitoring Requirements for Steam Electric Power Generating Facilities. The storm water event was triggered by accumulated snowfall and
.associated snow melt runoff. The analytical results can be seen tabulated below in Table 1.
Table 1. Storm Water Annual Iron Exceedance Values Benchmark Storm Water Sample Date Sample Analysis Analytical Monitoring Outfall Number Received Date Results (mg/L)
Requirement (mg/L) 1 1/15/2011 2/04/2011 16.0 5
2 1/16/2011 2/04/2011 9.0 5
9 1/15/2011 2/04/2011 5.7 5
The Tennessee Storm Water Multi-Sector General Permit for Industrial Activities requires informing the division's local Environmental Field Office (EFO) within 30 days from the time storm water monitoring results were received describing the likely cause of the exceedance.
Likely Cause of the Exceedance The likely cause of the exceedance 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 Brad Love at (423) 843-6714 or Stephanie Howard at (423) 843-6700 of Sequoyah's Environmental staff.
