DearL Sir:

)

Attached Discharge Monitoring Report for the Hope Creek Generating l Station for the month of August 1990.

- This report is required by and prepared specifically for the' l-

-Enviromental Protection Agency (EPA) and the New Jersey

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

only the observed results of measurements and analysis.

required to be-performed by the above agencies.cThe choice of the measurement devices and analytical methods are contrclled.

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.1 Accordingly, this report iis 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 suitability of any analytical or measurement' procedure.-

HJPDES 9/21/90 Explanation of Exceedances August 1990 The following. explanations are included to clarify possible or deviation from permit conditions.

General - The columns labeled "No. Ex", on the enclosed DNR, 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)

HHope Creek Generatin(g Station (17451)

_ In (77535)

-Talbot Laboratorying,c.

Final approval of limit change from COD to TOC has been received. 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

, interim thermal limits for discharge point 461A have been changed to 443 MBTU/hr (June - September) and 731 MBTU/hr

-(October - May).

NJPDES 9/21/90 Explanation of Exceedances August 1990 The following exceedances are included in the attached report

'andisqlained below. Exclusions have not endangered nor e

significantly. impacted public health or the enviroment.

DSN No.

EXPLANATION A recent system design change which was 4 61 C -

intended to reduce the inputs of water to the Rad Wasta systems, routed Air Chiller condensate drains to the Low Volume Oily Waste system. As a result of this change the associated Copper levels in the LV0W system increased to concentrations which exceeded permitted values.

Immediately following the identification of the source of Copper, the Air Chiller condensate drains were alligned to their original configuration.-
