• Public Service Electric and Gas Company P.O. Box E Hancocks Bridge, New Jersey 08038 Salem Generating Station 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. NJ000562z February 23, 1988 Attached is the Discharge Monitoring Report for Salem Generating Station containing the information as required in Permit No. NJ0005622 for the month of January, 1988. Thermal and flow data for DSN 481-486 is now available for October 1987 through December 1987 and has been forwarded under separate cover. 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. PDB:pad Attachments Very truly yours, /P-::if::tion/

• NJPUES Report .. Explanation of January, 1988

• 2/23/88 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. 481, 482 484-486 48C 87A EXPLANATION TRC -Chlorination rate reduced immediately to decrease TRC values. Situation aggravated by unit outages and loss of normal cooling water and seasonally lower demand. Differential Temperature

-Temperature limits were exceeded due to the loss of 3 of 6 circulating water system pumps. COD -Reported value exceeded permit limitation.

No cause has been identified as of report BOD, 5-day Percent Removal -Treatment plant has experienced a 55% reduction in flow since the last report and is in the process of stabilizing .

• NJPDES Report e Explanation of Deviations January, 1988 2/23/88 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. 48C 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). -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. 482,485 -Total residual chlorine values are at times unobtainable due to ongoing entrainment studies and the resultant equipment configuration.

Since all chemical treatments of or discharges to the circulating water system are common with at least one other discharge, those values are assumed to be identical for all parameters.

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.
