' Pursuant to Section 3.2 of Appendix B to Facility Operating License No. NPF-1 for the Trojan Nuclear Plant, the attached report is forwarded describing a violation of the NPDES Permit during July 1989. The violation involved exceeding the limit for Biochemical Oxygen Demand (BOD) in the sewage treatment plant effluent.

Sincerely.

PDrnend Ge:1eral Electric Coh1pany August 8. 1989 l ES-322-89L Trojan GOV REL 9C v ' I Oregon Department of Environmental Quality Northwest Region 0 Executive Building 811 SW Sixth Ave Portland OR 97204 Gentlemen:

Enclosed is the NPDES report for the Trojan Nuclear Plant for July 1989. Also enclosed are data required to be submitted in addition to that on standard NPDES forms.

The plant remained shutdown f or the entire month f or continuation of the annual refueling / maintenance outage.

The Sewage Treatment Plant Effluent BOD exceeded the 30 ppm maximum concentration limit on July 5, with a reported value of 31.7 ppm. There was no apparent reason for this high BOD as the plant was operating well within-effluent suspended solids at 6.2 ppm and turbidity at 2.6 NTU. This was probably a bad sample and not a true indication of plant effluent quality. The BOD for the following composite period was 3.8. ppm and remained within 3.8-5.2 ppm for the remainder of the conth. The Sewage Treatment Plant flow for the month was 406.000 gallons, with an additional 215,200 gallons being trucked to the St. Helens Sewage Treatment Facility.

The main plant outfall pH and chlorine monitors remained out of service duri'ng the entire month due to sample pump failures.

During periods of outage all required backup monitoring was performed.
