Dear Mr. Traina:
SEQUOYAll NUCLEAR PLANT - NPDES PERMIT NO. TN0026450 - NOTIFICATION OF CilANGE IN OUTFALL LOCATION
-M7
-Mg In accordance with Part II, Section D.1, of the NPDES permit, this is to notify you of a change in the discharge location for outfall serial No. (DSN) 112, sewage treatment plant effluent. Construction of the septic tank-sand filter system was completed.in late summer 1983. The original outfall location was identified as the plant intake basin; however, a design change will route the system's effluent to the yard drainage pond, DSN 102. Enclosed is a revised flow diagram illustrating this change.
The yard drainage pond presently receives the effluent from our operational septic tank-sand filter, DSN 111, and has an average flow (September 1979 to May 1982) of 4.32 MGD.
Because this pond presently receives sewage treatment plant effluent and the flow from DSN 112 (0.025 MGD) represents only 0.6-percent increase in the pond's total effluent flow, we do not believe an increase in effluent monitoring requirements for DSNs 112 and 102 is warranted.
The State of Tennessee certification for NPDES permit No. TN0026450 requires effluent monitoring for settleable solids from DSN 112 but not for DSN 111. Both wastewater treatment facilities are septic tank-sand filter systems, which typically do not have significant settleable solids in their discharges. We believe the monitoring requirements should be the same for both effluents because they are similar in character and have the same outfall location.
By copy of this letter, we request the State to modify its certification by deleting the limitation and monitoring requirements for settleable solids on DSN 112.
