| Title | Failure to Obtain Prior Approval for a Change Which Decreased the Effectiveness of the Emergency Plan |
| Description | The inspectors identified an apparent Severity Level III violation of 10 CFR 50.54(q) and an associated preliminary finding of low to moderate significance (White) for failing to obtain prior approval for an emergency plan change which decreased the effectiveness of the emergency plan. Specifically, on November 4, 2005, without approval from the NRC, the licensee removed instructions in emergency plan implementing procedures for making protective action recommendations for members of the public on the ocean within the 10-mile emergency planning zone, decreasing the plans effectiveness. The plan change, as implemented, resulted in a failure to meet the planning standard requirement of 10 CFR 50.47(b)(10) to develop and have in place procedures for the issuance of protective action recommendations (PARs) for the plume exposure pathway emergency planning zone, specifically, for areas of the ocean. This change constituted a decrease in effectiveness of the plan, and, therefore, implementing the change without prior approval from the NRC is a performance deficiency. This performance deficiency is more than minor because it impacts the Emergency Response Organization performance attribute of the Emergency Preparedness Cornerstone objective to ensure that the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. Using the examples in Table 5.10-1, Significance Examples 50.47(b)(10), of Appendix B to Inspection Manual Chapter 0609, "Emergency Preparedness Significance Determination Process," the inspectors concluded that this finding represents a degradation of the licensees risk-significant planning standard function. The required planning standard function was degraded because the licensees procedures did not direct the licensee to issue appropriate protective action recommendations to cover affected areas over the ocean within 5 to 10 miles of the site. The planning standard function was degraded, rather than lost, because default procedural actions of local governments would have resulted in effective protective actions for affected areas within 5 miles of the site. The finding does not present an immediate safety concern because, even without appropriate protective action recommendations from the licensee, the local governments would have ordered adequate protective actions for members of the public in the affected areas. No cross-cutting aspect is proposed as this performance deficiency occurred in 2005 and is not indicative of current licensee performance. |
