-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 sixty day notification of the review of Sequoyah Nuclear Plant's Storm Water Pollution Prevention Plan (SWPPP) and summary of the Best Management Practices (BMPs) modifications and additions for the exceedance of the benchmark monitoring requirement for total recoverable iron at Storm Water Outfall Nos. 1, 2, and 15: 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 re-sampled for total recoverable iron on August 17, 2010 based on high iron results earlier in the year (reference thirty day notification dated April 01, 2010). The analytical monitoring results for Storm Water Outfalls Nos. 1, 2, and 15 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 17 has not been re-sampled, to date, due to the lack of a qualifying event and/or no flow conditions.

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 Nos. 1, 2, and 15. A brief summary of the proposed modifications, including a timetable for implementation, follows.Storm Water No. 1 Per the SQN SWPPP, there are no paved surfaces in this drainage area. Ground cover consists of rip-rap and grass.The following modifications will be made by 12/31/10:
Gravel will be added to the base of the hill prior to the culvert and rip rap will be added to the drainage ditch.Storm Water No. 2 Per the SQN SWPPP, there are no paved surfaces in this drainage area. Ground cover consists of crushed stone, gravel, and grass. Drainage ditches are equipped with check dams as BMPs.The following modifications will be made by 12/31/10:
More gravel will be added prior to the inlet of the pipe. Rip rap will be added in the area approaching the guard rail.Storm Water No. 15 Per the SQN SWPPP, there are no paved surfaces in this drainage area. Ground cover consists of rip-rap and grass. Rock lined drainage ditches are equipped with check dams as BMPs.The following modifications will be made by 12/31/10:
