Dear Mr. Ellam:
Three Mile Island Nuclear Station (TN2)
Detailed below is the infor=ation necessary to qualify all TMI " ponds" for a waiver from the permit requirements of Section 6(c) of the Dam Safety Encroachmeno Act of October 23, 1979.
ACRE POND FEET HAZARD POTENTIAL 1.

Unit I Cooling Tower desilting basin 3.1 3
5.
Unit 2 Cooling Tower desilting basin 3.1 3
6.
Site (Stormwater) Runoff desilting basin 3.3 3
In all instances, construction began prior to July 1, 1979.
All of the above " ponds" ;re located on Three Mile Island.
Three Mile Island is tocated in the Middletown Quadrangle of the U.S.G.S.
Map System.
A po*'. on of the Middletown quadrangle is enclosed and the approximate 1;;4tions of the ponds are annotated thereon.
In addition, a diagram which was submitted to PaDER as a part of our NPDES permit application is also enclosed.
This diagram further details locations of these ponds (as well as other items).
The following is a brief description of the ponds:
1.
Ponds 1 and 2 (Pre-coerational settling basins)
These basins were used at the time of plant construction.
Currently, they are j ust being drained, as necessary, in order to remove accumulated Metrocontan Ecson Comcany is e Memter of the Genera: Suche utsties System
J. E11gc TLL 698
-1 rainwater. All such discharges are cade in accordance with the provisions of our NPDES permit which is administered by the PaDER.
2.
Pend 3 (Dred:ine settline basin)
As periodic dredging is perforned, accumulated solids are retained within this basin.
Dredging operatiocs are conducted in accordance with the provisions of our AC0E and PaDER permits.
3.
Ponds 4 and 3 (Unit 1 and 2 Coolin: Tower des 11 ting basins)
These basins are used infrequently during cleaning operations. Cleaning is conducted in accordance with PaDER requirements.
4.
Fond 6 (site (Stor= water) Runoff desiltine basin)
This area allows rainfall runoff fro = the TM1 plant site to " settle" (in order to minimize the solids concentration of the runoff) prior to entering the Susquehanna River. This discharge is in accordance with our NPDES Per=it.
All the ponds referenced in this submittal are located on Three Mile Island and comply with the exemption detailed in section 105.12(a)4 of the regulations regarding the National Wild and Scenic Rivers Act and the Pennsylvania Scenic Rivers Act.
In addition to the six " ponds" detailed herein, the plant site is surrounded by a dike and the shoreline surrounding the plant site is rip-rapped with stone.
Both of these measures were pe* formed in order to meet Nuclear Regulatory Commission requirements (for Good protection).
In accordance with section 105.12(b)4 of the regulations, these items are exempt from these regulations.
TMI has a number of small containment structures which were installed to comply with SPCC regulations (spill prevention). These structures are essentially limited to curbing and walls surrounding our oil tanks. These SPCC structures are also exempt from these regulations.
Per section 105.12(b)6 of the regulations, the TMI intake structures and discharge outfalls (which are all detailed in our NPDES permit application on file with PaDER) are exempt from these regulations.
Should you require any additional information, please contact Mr. Eric Nielsen of our Licensing staff at (717) 948-8562.
Sincerely, qf I
