NPF-10 and NPF-15 for San Onofre Nuclear Generating Station (SONGS), Units 2 and 3, require violations of the National Pollutant Discharge Elimination System (NPDES) permit or State Certification (pursuant to Section 401 of the Clean Water Act) to be reported to the NRC by submittal of copies of the reports' required by the NPDES permit or certification.
This letter provides copies of the April 1996 NPDES discharge monitoring reports for SONGS, Units-2 and 3.
As discussed in the enclosed reports,
-on April 20, 1996, 22,440 gallons of water with a pH of 12.6 was released from the High Flow Makeup Demineralizer waste neutralization tank.
This release exceeded the California Code of Regulations, Title 22, pH limit of 12.5.
In addition, while a sample for total suspended solids was not analyzed for this release, it is estimated that the NPDES permit instantaneous limit of 100 mg/l was exceeded, due to the precipitation of magnesium and calcium hydroxyls at high pH levels.

SUBJECT:
NPDES Discharge Monitoring Report San Onofre Nuclear Generating Station, Unit 2 i
Dear Mr. Robertus:
]
The NPDES Discharge Monitoring Report (DMR) for San Onofre Unit 2 covering the month of April is submitted in accordance with the requirements of Order No. 94-49 (NPDES Permit No.
CA0108073). A summary of the generating unit's status and significant analytical results is provided below.
The unit was operational all month. All sampled water sources were found to be within permit limits with the following exception. On April 20 at 1810, a release of 22,440 gallons of water with a pH of 12.6 from the High Flow Makeup Demineralizer (HFMUD) Waste Neutralization Tank occurred. The water released from this tank exceeded the pH limit of 12.5 as specified in Title 22 of the California Code of Regulations. The amount of caustic released was however below the reportable quantity level specified by these regulations. Notifications to all of the required agencies were completed on April 22 at 1530. Although a sample for total suspended solids (TSS) was not analyzed for the release, it is believed that the 12.6 pH water resulted in a release above the instantaneous limit of 100 mg/l specified in the NPDES Permit due to magnesium and calcium hydroxyls that come out of solution at that pH level. An investigation of the incident occurred and has resulted in greater supervisory controls of the operations at the HFMUD. We believe that these actions along with additional training requirements should prevent such an occurrence from happening again in the future.
Pursuant to Order No. 94-49. Reporting Requirement 10, the following representative has prepared and is authorized to sign the reports required by this order: Robert K. Heckler, Environmental Engineer.

Mr. John Robertus Califo nia Regional Water Quality Control Board San Diego Region 9771 Clairemont Mesa Boulevard, Suite B San Diego, California 92124-1331
SUBJECT:
NPDES Discharge Monitoring Report San Onofre Nuclear Generating Station, Unit 3
Dear Mr. Robertus:
The NPDES Discharge Monitoring Report (DMR) for San Onofre Unit 3 covering the inonth of April is submitted in accordance with the requirements of Order No. 94-50 (NPDES Permit No.
CA0108181). A summary of the generating unit's status and significant analytical resuas is provided below.
The unit was operational all month. All sampled water sources were found to be within permit limits with the following exception. On April 20 at 1810, a release of 22,440 gallons of water with a pH of 12.6 from the High Flow Makeup Demineralizer (HFMUD) Waste Neutralization Tank occurred. The water released from this tank exceeded the pH limit of 12.5 as specified in Title 22 of the California Code of Regulations. The amount of caustic released was however below the reportable quantity level specified by these regulations. Notifications to all of the required ajencies were completed on April 22 at 1530. Although a sample for total suspended solids (TSS) was not analyzed for the release, it is believed that the 12.6 pH water resulted in a release above the instantaneous limit of 100 mg/l specified in the NPDES Permit due to magnesium and calcium hydroxyls that come out of solution at that pH level. An investigation of the incident occurred and has resulted in greater supervisory controls of the operations at the HFMUD. We believe that these actions along with additional training requirements should prevent such an occurrence from happening again in the future.
Pursuant to Order No. 94-50, Reporting Requirement 10, the following representative has prepared and is authorized to sign the reports required by this order: Robert K. Heckler, Environmental Engineet.
