Tennessee Valley Authority, Post Office Box 2000, Soddy Daisy. Tennessee 37384-2000 March 20, 2013 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.
TNR050015 SECTOR 0 EXCEEDANCE OF THE BENCHMARK MONITORING REQUIREMENT.
Please find enclosed the thirty day notification, the lab analysis for the exceedance of the benchmark monitoring requirement for total recoverable iron for Storm Water Outfall Number 3, the sixty day notification of the review of Sequoyah Nuclear Plant's Storm Water Pollution Prevention Plan (SWPPP), and a summary of Best Management Practices (BMPs) modifications and additions to mitigate future exceedance of total recoverable iron.
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 11, 2013. The storm water analytical monitoring results were received on February 25, 2013. The analytical monitoring results for Storm Water Outfall Number 3 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 qualifying event resulted from a four hour rainfall on the morning of January 11, 2013. The analytical results can be seen tabulated below.
Table 1. Storm Water Annual Iron Exceedance Values Storm Water Sample Backup Analytical Averaged Benchmark Outfall Sample Analysis Sample Results Results Monitoring Number Date Received Analysis (mg/L) (mgRL) Requirement Date Received (mg/L) 3 1/11/2013 2/25/2013 03/05/2013 8.4; 6.7 8 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 iron concentration in the native soil around the storm water outfall and the presence of exposed steel which had been temporarily staged in the area.
SWPPP Review and Modification Timeline Sequoyah Nuclear Plant's SWPPP has been reviewed to determine the modifications and additions to the plan which would assist in reducing the iron effluent concentration at Storm Water Outfall Number 3. A brief summary of the proposed modifications, including a timetable for implementation follows.
Storm Water Number 3 Per the SQN SWPPP, ground cover consists of crushed stone, gravel, and grass. Drainage ditches are equipped with rip rap and filter socks as best management practices.
The exposed steel and temporary material storage near storm water oufall number 3 will be removed by 3/30/2013.
If you have any questions or need additional information please contact Brad Love of Sequoyah's Environmental staff by phone at (423) 843-6714 or by e-mail bmlove@tva.gov.
