. This definition is used in conjunction with 10 CFR 50.54(q)(3), which allows a licensee to make changes to its emergency plan if it can demonstrate through analysis that the change does not DG-1324, Page 18 reduce the effectiveness of the plan. The 10 CFR 50.54(q) change process starts when a licensee decides to make a change to its’ emergency plan; an intentional act on the part of the licensee. c. Typical emergency plans identify and rely on resources, capabilities, and methods that are not under the cognizance of the licensee’s emergency planning group but instead are maintained by other entities that may modify those resources, capabilities, and methods. (The effect of proposed plant modifications on the effectiveness of the licensee’s emergency plan should be considered by the plant change control processes.) If the licensee changes its emergency plan under 10 CFR 50.54(q)(2) to reflect these modifications, the change process in 10 CFR 50.54(q)(3) would apply, and the change analysis would need to address whether the change constitutes a reduction in effectiveness. For example, an offsite fire department identified and relied upon in the licensee’s emergency plan is no longer able to respond to the plant site because of conflicting responsibilities assigned in the local ORO plans. When the licensee revises its emergency plan to identify a replacement response capability, the evaluation would need to address the differences in response time, equipment resources, and other elements on the effectiveness of the plan. d. Temporarily taking a resource, capability, or method out-of-service for maintenance or testing, or an unplanned outage thereof, does not constitute a change to the emergency plan if the language of the plan is not changed. To comply with 10 CFR 50.54(q)(2), the licensee should minimize the duration of the outage, or carry out viable compensatory measures. The 10 CFR 50.54(q)(3) process does not apply in these cases unless the emergency
