system other than a groundwater monitoring system composed of wells, the ER should describe the program used for preventing, detecting, and responding to inadvertent releases of radioactive materials into the groundwater. 4.6 Ecology General Approach for Information and Analysis Content for All Ecological Issues The ER should provide sufficient information to put any effects of plant operation in perspective in terms of stability of populations and other such properties of ecosystem structure and function and alteration in ecosystem services. Ecosystem services refers to a wide range of conditions and processes through which natural ecosystems, and the species that are part of them, help sustain and fulfill human life. For all ecological issues, the same general approach can identify the environmental consequences of license renewal and its alternatives. This approach, consisting of the steps detailed below, generally follows the EPA framework for ecological risk assessment: 1. Identify the Relevant Sources of Information While Chapter 3 should generally describe the environment, this section should identify the specific information and sources used for assessing impact and include the following: Studies and monitoring programs. Briefly summarize any studies or monitoring programs that provide site-specific data and explain environmental impacts. Include the location, dates, objectives, biological entities or attributes chosen for study, methods, and results applicable to this license renewal application, as well as any data or data summaries that might be available for NRC review. If data are older than 5 years old, explain why the studies would or would not be relevant for assessing the effects of present and projected future plant operation over the term of license renewal. For example, demonstrate that both the potentially affected resources and the effect of the plant on them have remained and can be expected to remain unchanged over the term of license
