Public SeNice Electric and Gas Company P.O. Box 236 Hancocks Bridge, New Jersey 08038 Nuclear Department George Caporale - Chief Bureau of Permits Admin.
Division of Water Resources CN-029 Trenton, NJ 08625 Dear Mr. Caporale NEW JERSEY POLLUTANT DISCHARGE ELIMINATION SYSTEM DISCHARGE MONITORING REPORTS SALEM GENERATING STATION PERMIT NO. NJ0005622 September 19, 1988 Attached is the Discharge Monitoring Report for Salem Generating Station containing the information as required in Permit No.
NJ0005622 for the.month of August, 1988.
This report is required by and prepared specifically for the Environmental Protection Agency (EPA) and the New Jersey Department of Environmental Protection (NJDEP).
It presents only the observed results of measurements and analyses required to be performed by the above agencies.
The choice of the measurement devices and analytical methods is controlled by EPA and NJDEP, not by-the company, and there are limitations on the accuracy of such measurement devices and analytical techniques even when used and maintained as required.
Accordingly, this report is not intended as an assertion that any instrument has measured, or any reading or analytical result represents, the true value with absolute accuracy, nor is it an endorsement of the suitability of any analytical or measurement procedure.
Exclusion explanations are included on additional pages.

NJPDES Report Explanation of lusions
- 9/19/88 August.. 1988 The following exclusions are included in the attached report and explained below.
Exclusions have not endangered nor significantly impacted public health or the environment.
DMR NO.
481, 484, 486 484 48C 487 EXPLANATION COD -
As no known causative agent exists for the introduction of COD into DSN's 481-486, sampling deficiencies are suspected to be present.
While the net increase in COD on these three DSN's exceeded permit*
limits, actual net change across all DSN's (481-486) showed a net increase of only 27.98 ppm, which is below our discharge limit of 50 ppm.
TSS -
As no known causative agent exists for the introduction of TSS into DSN's 481-486, sampling def icienies are suspected to be present.
While the net increase in TSS on this DSN exceeded permit limits, actual net average TSS on all DSN's (481-486) was net negative (decr~ased) and.-is reported as 0.00.
Ammonia -
The source of the ammonia has been identified as to its in-plant source.
Work is proceeding on eliminating ammonia from this discharge.
Temperature -
The tempera~ure.of this outfall is monitored prior to mixing in the re~eiving stream at an average flow rate of 7 gpm.
Due to the extreme weather conditions experienced during August, less heat dissipation occurred than anticipated by original design.
- Though in exceedance of absolute permit.
limitations, this discharge *
. 0 temperature was equal to (31 C) the receiving body of water temperature, which on the dag in question varied between 29.6 C 0
and 31. 2 C.

NJPDES Report
- Explanation of viations Augus~, 1988
- 9/19/88 The following explanations are included to clarify possible deviations from permit conditions.
General -
The columns labeled, "No. Ex.", on the enclosed DMR, tabulate the number of daily discharge values outside the indicated limits.
Data reporting and accuracy reflect the working environment, the design capabilities and reliability of the monitoring instruments and operating equipment.
All reported concentrations are based on daily discharge values.
Total residual chlorine is pertormed once per eight hours of chlorination unless otherwise indicated.
Analytical values which are less than detectable are reported as zero unless otherwise indicated.
Analytical results for all parameters other than pH, temperature, TSS and TRC are provided by Century Laboratories (NJDEP certification 08153).
48C
- Clarifier - Effluent pH is reported for informational purposes only.
487,489 - Measurements are obtained from single grab samples unless sampling protocols are met. _ Direct flow measurement is impossible ~t this location.
Reported values are based upon National Weather Service Data in accordance with the agreement reached with NJDEP on 2/10/88.
481-486 - Chlorination of the circulation water system normally does not occur except as otherwise noted.
Service water system chlorination is normally continuous and is monitored on the circulating water system outfall due to the inability to sample service water effluent directly.
Chlorination of both systems will be indicated by results reported for both and represents their combined affect upon the circulating water outfall.
