Nuclear Regulatory Commission Attn: E. W. Merschoff, Regional Administrator Region IV Parkway Central Plaza Building 611 Ryan Plaza Building, Suite 400 Arlington, Texas 76011-4085 Docket No. 50-312 Rancho Seco Nuclear Station License No. DPR-54 NATIONAL POLLUTANT DISCIIARGE ELIMINATION SYSTEM (NPDES) PERMIT NO. CA0004758

Dear Mr. Merschoff:

In accordance with a condition specified in the NRC Safety Evaluation Report for License Amendment No. 45 to Facility Operating License No. DPR-54, the District is required to notify the NRC concerning Rancho Seco NPDES wastewater discharge permit violations. Enclosed is a copy of the Rancho Seco Monthly Discharger Self Monitoring Report for February 1998, which makes note of one wastewater discharge permit violation.

Because of heavy rains during the reporting period, the Rancho Seco Park wastewater treatment pond freeboard level was reduced to less than its required two feet minimum during February. On February 24,1998, Rancho Seco personnel recorded the lowest amount of Rancho Seco Park wastewater treatment pond freeboard at 1.9 feet. The pond freeboard remained at or above the minimum required two feet beginning on March 10,1998.
