Box 800 Rosemead, California 91770 Docket No. 50-361 Construction Permit No. CPPR-97 NOTICE OF VIOLATION Based upon the results of an NRC inspection conducted on November 5-9, 1979, it appears that one of your activities was not conducted in full compliance with conditions of your NRC Construction Pemit No. CPPR-97 as indicated below:
