r PHILAD ELPHI A ELECTRIC COM PANY 23ol M ARKET STREET P O. BOX 8699 PHILADELPHI A. PA.19101 12151841 4000 June 20, 1988 Mr. Jim Newbold Chief, Permits Section Department of Environmental Resources i
1875 New Hope Street Norristown, PA 19401 RE:
Limerick Generating Station Supplemental NPDES Permit Application Discharge Information
Dear Mr. Newbold:
In response to Mr. Joe Ghaben's request attached is i
information that indicates the expected discharges of our i
NPDES permitted chemical additives based upon completion of unit two.
The cooling water additives will be used for both cooling towers at similar treatment and discharge rates.
Other chemical additives which could be released are Nox-fish, Ultrion 8157, and sodium nitrite.
Nox-fish is a rotenone based product applied annually upon i
approval to our emergency spray pond.
The level of the spray pond is lowered and the spray pond. drainage lines are closed before treatment to prevent discharges during treatment with the chemical.
Ultrion 8157 is a flocculating agent used in the raw water clarifier.
Approximately twenty gallons of Ultrion will be used daily.
Since the chemical binds with dirt particles, it is highly unlikely that free chemical would be present in the final effluent.
Sodium nitrite is used in plant closed cooling systems.
When these systems are drained, their waste water is discharged through the holding pond.
This occurs a few times a year at most and the nitrite concentration at the final discharge point should not exceed ten parts per million.
