' Observations and Findinas The inspectors reviewed the Offsite Dose Calculation Manual and appropriate plant procedures and found them adequate. Minor changes had been made to the Offsite

Dose Calculation Manual; however, the inspectors did not identify any items of concern. Management controls were appropriate; annual reports were written and submitted to the NRC as required. The annualland use census was performed as require The inspectors noted that the control air samr'er was appropriately located in Sector O (NW), when using the original siting wind rose data from a study conducted between January 25,1973, and January 24,1976. However, wind

'

rose data from a study conducted between 1979 and 1983 to determine prevalent

.

wind directions at San Onofre Nuclear Generation Station indicated that the control air sample station was not in the least prevalent wind direction but in the fifth least q prevalent wind direction, in which an air sample station could be positioned. The inspectors determined that the licensee's current control station satisfied regulatory requirements based on meteorological conditions that existed when the original

environmental monitoring program was approved. However, this matter will be referred to the Office of Nuclear Reactor Regulation to evaluate the generic implications and if any actions should be taken when meteorological conditions 2 chang l Conclusions Overall, a good radiological environmental monitoring program was implemented in accordance with the Offsite Dose Calculation Manual.

Additionally, the control air sample was collected and packaged by personnel employed by Southern California Edison but not assigned to the San Onofre Nuclear Generation Station staf Conclusions The inspectors determined that the present organization maintained an adequate staff and provided management support for implementing the radiological environmental monitoring progra R7 Quality Assurance in Radiological Protection and Chemistry Activities R7.1 Audits and Surveillances (84750) Insoection Scone Quality assurance audits and surveillances concerning the radiological environmental monitoring and meteorological programs were reviewed for scope, thoroughness, and timely follow-up of identified deficiencie Observations and Findinas The inspectors reviewed the audit plan, checklist, and results for the audit performed by the licensee in December,1996. Three surveillances performed between 1994 and 1996 were also reviewe The audit was comprehensive, thorough, and provided management with the appropriate oversight of the radiological environmental monitoring program. Two problem review reports and two improvement opportunities involving; the lack of rw Mure requirements for the re-training of personnel, the lack of procurement upplier assessment, the lack of a Nuclear Oversight Division review of the 1995 Annual Radiological Environmental Operating Report prior to issue, and the generic use of the training records information management system (TRIMS) encode "ENV 600" for training documentation, were identified during the audit. The recommended corrective actions were being eva'uated by the licensee during this inspectio The inspectors determined that the quality assurance auditors assigned to perform the audit and surveillances had appropriate radiological environmental knowledge and experience, which enabled them to properly assess performance and identify problem ,

.

-10-During the review of the Topical Quality Assurance Manual Revision 13, which became effective on December 20,1996, the inspectors noted that the audit frequency requirement for the environmental program stated, "The conformance of unit operation to provisions contained within the Technical Specifications, the Licensee Controlled Specifications, and applicable license conditions shall be audited at least once every 12 months." In discussions with nuclear oversight division management, the inspectors were informed that the actualintent of the environmental audit frequency was to be once every four years as stated in Revision 12 of the Topical Quality Assurance Manual. The licensee stated that they would clarify the wording in Revision 13 to comply with their original inten The licensee performed proper audits of the contract laboratory responsible for the collection of aquatic environmental samples and the contract laboratory responsible for analyzing environmental samples. The licensee's contractor laboratory participated in a intercomparison program and results were forwarded to the licensee, Conclusions A good, comprehensive audit was performed which identified items for improvement and evaluated the performance and implementation of the radiological environmental monitoring program. The audit and surveillances were performed by )

qualified auditors. The wording in the frequency section of Table 1-E-1 of '

Revision 13 of the Topical Quality Assurance Manual did not clearly state the licensee's intent. Audits were performed at the required frequenc R8 Miscellaneous Radiological Protection and Chemistry issues R8.1 Annual Environmental Ooeratina and Effluent Release Reports (84750) Insoection Scone The inspectors reviewed the Annual Radiological Environmental Operating and Annual Radioactive Effluent Release Reports concerning the radiological environmental monitoring program activities to determine compliance with the requirements of Technical Specifications and the Offsite Dose Calculation Manua These reports were reviewed for omissions, obvious mistakes, anomalous measure-ments, observed biases, trends in the data, and laboratory inter-comparison Observations and Findinas Sampling results included in the 1994, and 1995 Anrual Radiological Environmental Operating Reports indicated that sampling was performed as require .. _ _ . . . . . _ _ _ _ _ _ _ ~. - __ . . _ ___ ._ . _ . _ - _ . . . . _ _ _ _ _ _ _ _ . _ . -_
