Box 236 Hancocks Bridge, New Jersey 08038 Nuclear Department CERTIFIED MAIL RETURN RECEIPT REQUESTED ARTICLE NUMBER: P 063 762 096 JUN QS 1992 NLR-E92164 Bureau of Discharge Prevention NJ Department of Environmental Protection and Energy 401 East State Street CN-027 Trenton, New Jersey 08625-0027 Attention: Discharge Confirmation Report

Dear Sirs:

PUBLIC SERVICE ELECTRIC AND GAS COMPANY SALEM GENERATING STATION (CASE #92-05-0T-1647-38)

As per the requirements of NJAC 7:1E-5.8, PSE&G has prepared the

  • attached report confirming the discharge to the ground of approximately 500 gallons of water containing a hydrazine concentration of 0.03 mg/l. The discharge was due to an overflow of the No. 2 Auxiliary Feedwater Storage Tank (AFST) at the Salem Generating Station. The discharge, which occurred at the facility on May 6, 1992, occurred entirely within PSE&G property and no injuries resulted.

The discharge of hydrazine is regulated under 40 CFR 302.4 with a reportable quantity of one (1) pound. As the discharge did not exceed the reportable quantity, no notification of the release was reported to any agency other than the New Jersey Department of Environmental Protection and Energy (NJDEPE) and the Nuclear Regulatory Commission (NRC) *, as required under 10 CFR 50. 72, Significant Events.

PSE&G believes it acted in accordance with the intent of NJAC 7:1E, Subchapter 5, which requires all major facilities to notify the NJDEPE of discharges of petroleum and other potentially hazardous substances in any concentration. As a result of this discharge, PSE&G has cleaned the affected area and taken measures to prevent recurrence of this incident.

DISCHARGE CONFIRMATION REPORT - SUPPLEMENTAL INFORMATION RELATED TO REPORTED DISCHARGE HYDRAZINE SALEM GENERATING STATION

- CASE #92-05-07-1647-38 MEASURES TAKEN TO CONTAIN, CLEANUP AND REMOVE THE DISCHARGE:

Upon discovery of the overflowing tank, Operations personnel immediately closed the fill valve and called Chemistry personnel so that the overflow could be analyzed.

The following day a dilute solution of hydrogen peroxide was mixed with the residual liquid which neutralized the remaining hydrazine. Chemical analysis confirmed that the hydrazine concentration was less than the method detection limit (<10 ppb) and the remaining puddles were allowed to evaporate.

The estimated cost for analysis and cleanup of this discharge is estimated .to be $500.

CORRECTIVE MEASURES:

An extension has been added to the overflow line on the tank in an effort to divert any future overflows to a contained area.

The importance of clear communication and timely reporting has been reemphasized to applicable plant personnel.

INDIVIDUAL(S) INVOLVED IN CONTAINMENT/CLEANUP:

The individual responsible for the cleanup and disposal of the contaminated material is:

Susan Miller Chemistry supervisor Public Service Electric & Gas Chemistry Department PO Box 236, MC S-07 Hancocks Bridge, NJ 08038 (609)339-2649 David Hurka Lead Engineer Public Service Electric & Gas Environmental Licensing PO Box 236, MC N-21 Hancocks Bridge, NJ 08038 (609)339-1275
