Department of Enviromental Protection'(NJDEP). It presents  ;

L only the observed results of measurements and analysis-  ;

i required to be performed by the above agencies. The choice of i the measurement devices and-analytical methods are controlleds ,

by the' EPA and the 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 that.any ,

reading analytical result represents the true value with-  :

absolute accuracy, nor is it an endorsement of the- i suitability of any anlytical or' measurement procedurs.  ;

O NJPDgg 8/22/90 Explanation of Exceedansis May 1590 The following explanations are included to clarify possible deviation 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 enviroment, the design capabilities and reliability of the monitoring instruments and operating equipment.

Analytical values performed by the following NJDEP certified laboratories:

NET Atlantic, Inc. 08153)

Hope Creek Generatin(g Station (17451)

In (77535)

Talbet Laboraton1ng,c.

South Jersey Test Inc. (06431) c O Deviations from required sampling, analysis monitoring and reporting methods and periodicities are noted on the respective DNR.

Final approval of limit change from CCD to TOC has been raceived. Analytical results for TOC are included.

As per the Administrative consent order the TSS limit for .#

discharge points 462A, 463A and 464 have been lifted and the .F interia thermal limits for discharge point 461A have been changed to 443 NBTU/hr (June - Septener) and 731 MBTU/hr (October - May).

NJPDES 8/21/90 Explanation of Exceedances May 1990 The following exceedances are included in the attached report and explained below. Exclusions have not endangered nor significantly impacted public health or the enviroment.

DSN No. EXPLANATION.

461 C - On the original May DMR submitted to the NJDEP, PSE&G used a consecutive 30 day period for reporting TS5 values for the Low Volume Oily Waste system. This was in accordance with NJAC 7:14A-1.9, and covered the 30 day consecutive period from May 3rd to June 2nd.

As per E. J. Keatings conversation with Steve Matsis of the SBRE, it was his interpretation that this was not an acceptable method for determining a monthly average. As a result of this conversation it was decided that a corrected DMR be sent to the NJDEP showing the average TSS value as 31.125 mg/l instead of the 26.8 g/l that was previously reported. During your future reviews,1f the 30 consecutive day method for averaging is O deemed to be an acceptable alternative, the average value can be determined from the results of the following analysis:
