al for impacts. The magnitude of impacts would depend on the nature of the activity, the status of the resources that could be affected, and the effectiveness of mitigation. Specifically, 10 CFR 51.53 (c)(3)(ii)(E) requires, in part, “All license renewal applicants shall assess the impact of refurbishment and other license-renewal-related construction activities on important plant and animal habitats.” The applicant should describe any activities associated with license renewal and continued operations, maintenance, and refurbishment that will disturb terrestrial habitat. If no area will be disturbed, the ER should note that fact and no further discussion of the issue is needed. Chapter 4 of the ER should describe areas that will be disturbed with respect to (1) the amount of land to be disturbed, (2) ecological characteristics of the habitat, (3) species of plants and animals found in the area, and (4) the extent to which the habitat is unusual. Note that the information and analysis for this issue overlaps the information and analysis for assessing impacts on threatened and endangered species. Information and Analysis Content The ER should follow the general approach for information and analysis content for all ecology issues as described at the beginning of this section. In addition, if a license renewal activity will disturb any plant or wildlife habitat, the ER should describe any land that will be disturbed during transport and delivery of equipment, structures, or components; material laydown areas; or construction associated with refurbishment. If any temporary or permanent structures will be built, the ER should provide a map of the site that includes the proposed location of these structures. If any road or bridge modifications will occur as a result of transport, the ER should describe the potential effects on the terrestrial environment.
