Limerick Generating Station WQ/GeneralIW Correspondence Limerick Township Montgomery County

Dear Mr. Matty:

On August 9,1996 authorization to discharge wastewater from the dredging of the Schuylkill River Pumphouse wet wells of the Limerick Generating Station to the Schuylkill River was granted. The one week dredging of the wet wells was scheduled to begin August 12,1996. The wastewater from the dredge material

, discharges to the Schuylkill River at Outfall 012 of the NPDES Permit PA0051926.

On August 12,1996 during our telephone conversation and through your August 12,1996 letter it was told that the dredging would be done in the Schuylkill River at a locationjust in front of the intake structure of 1 the Limerick Generating Station instead of the pumphouse wet wells.

)

We have completed our review of the information contained in your August 12,1996 letter and hereby approve your request subject to the conditions 1 through 4 of our previous approval dated August 9,1996.

If you have any questions, please contact me.

Sincerely.
