The analysis'ndicated a TRC concentration of 0.76 mg/l.

The sodium hypochlorite flow to the systems was immediately reduced. At 1404 hours0.0163 days <br />0.39 hours <br />0.00232 weeks <br />5.34222e-4 months <br />, a grab sample analysis indicated the concentration of, TRC had decreased to 0.22 mg/l. At 1414 hours0.0164 days <br />0.393 hours <br />0.00234 weeks <br />5.38027e-4 months <br />, the TRC concentration had decreased to 0.03 mg/l.

The daily maximum value for TRC during the time of chlorination was 0.18 mg/l.

'\

A malfunctioning non-essential service water flow meter has been identified as a contributing factor to the event. The flow meter is scheduled for replacement prior to resumption of chlorination activities on the non-essential service water systems.

By copy of this letter, the Nuclear Regulatory Commission is notified pursuant to thc requirements of Appendix B, Part II, Nonradiological, Environmental Protection Plan, Section 3~20 Very truly yours, Donald L.
