and its implementation; • rectifying the impact by repairing, rehabilitating, or restoring the affected environment; • reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action; and • compensating for the impact by replacing or providing substitute resources or environments. The applicant should identify in the ER all relevant, reasonably foreseeable mitigation measures that could reduce or avoid adverse effects, even if they are outside the jurisdiction of the NRC. The applicant should provide the reason why the mitigation measures are considered reasonably foreseeable. A mitigation measure can be considered reasonably foreseeable if, for example, it is 1) required by the NRC as a license condition (e.g., a requirement imposed pursuant to 10 CFR 50.54 (aa)), 2) required or likely to be required by another regulatory agency (e.g., USACE), or 3) mitigation that the applicant has stated to the NRC (e.g., in the Environmental Report) that it would perform. Where mitigation measures would be required by a license condition that should be clearly stated in the ER. Where applicable, the applicant should specify what Federal, state, or local laws require the mitigation measures, or if there is (or is expected to be) a Federal, state, or local permit that requires the particular measures. The applicant should clearly explain the requirements that are being imposed by the DG-4026, Page 21 regulatory agency with authority over the resource and state how it relied on the mitigation to determine the impact level by discussing how the mitigation will be accomplished and whether it is expected to lower the impact level. For example, for a project where a wetlands mitigation plan is required by a state permit issued to the applicant and/or by state laws and regulations, the applicant should consider this information in the ER.
