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 June 10, 1988 Attached is the Discharge Monitoring Report for Salem Generating Station containing the information as required in Permit No.
NJ0005622 for the month of May, 1988.
A corrected page for the.
April, 1988 DMR is also included.
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 additi~nal pages.

Explanation of Ex~usions May, 1988 6/10/88 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.
484.,.
48C 487A 489 EXPLANATION TSS, COD -
As no known causative agent exists for the introduction of TSS or COD into DSN's 481-486, sampling deficiencies are suspected to be present.
Alternative sample locations are being investigated.
Net. increase in COD on this DSN exceeded permit limits.
Actual net change across all DSN's (481-486) showed a net increase of 19.70 ppm, which is below our discharge limit of 50 ppm.
Net in-crease in TSS on this DSN exceeded permit limits.
Actual net change across all DSN's (481-486) showed a net increase of 9.59 ppm, which is below our discharge limit of 30 ppm.
- TSS, COD, NH3 -
Elevated levels of indicated parameters are attributed to a failed clarifier blowdown valve which is currently undergoing repair.
BOD LOADING, REMOVAL EFFICIENCY -
Plant operational efficiency was impaired during the regular monitoring period by the failure and restoration of the collection system's ejector stations, which had the net result of causing a hydraulic overload on the day prior to sample collection.
TSS - Elevated value traced to inadequate sample technique.
Later resample result was within permit limits.
NJPDES Report e*_
6/10/88 Explanation of Deviations May, 1988 The following explanations are ~ncluded to clarify possib~e 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 performed 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 at 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.
