NOT!t,C Of VIOLATION Arizona Public Service Co. Docket No. 50-529 Palo Verde Unit 2 License No. NPF-51 During an NRC inspection conducted on August 25 through September 30, 1992, a violation of NRC requirements was identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Action," 10 CFR Part 2 Aspendix C, the violation is listed below:

Wit ? Technical Specification 6.8.1 states in part: " Written procedures shall be a lsbilshed, implemented, and maintained covering the activities

... recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February, 1978."

Appendix A of Regulatory Guide 1.33, Revision 2, recommends procedures for safe operation and shutdown.

Procedure 40AC-90P02, " Conduct of Shift Operations," step 3.2.2.8, which implements in part the operations procedures recommendation of Regulatory Guide 1.33, requires that "On shift personnel shall be aware of and responsible for plant status ... They shall be attentive to instrumentation and respond to abnormal indications until corrected or verified to be false by other instrumentation."

Contrary to the above, on September 3, 1992, Unit 2 control room personnel were not attentive to plant instrumsatation and failed to respond to an abnormal alarm indication caused by high level in the non-ESF sump in the Auxiliary Building which later resulted in flooding of the Auxiliary Building.

This is a Severity Level IV violation (Supplement I) applicable to Unit 2.

Pursuant to the provisions of 10 CFR 2.201, Arizona Public Service Company is hereby required to submit a written statement or explanation to the U. S.
