6 National Environmental National Environmental Policy Act Policy Act 3/4 NEPA requires Federal agencies to use a systematic approach to consider environmental impacts 3/4 Commission has determined that an environmental impact statement (EIS) will be prepared for a license renewal action
7 Decision Standard for Decision Standard for Environmental Review Environmental Review To determine whether or not the adverse environmental impacts of license renewal for ANO, Unit 2 are so great that preserving the option of license renewal for energy planning decisionmakers would be unreasonable.

3/4 SMALL: Effect is not detectable or too small to destabilize or noticeably alter any important attribute of the resource 3/4 MODERATE: Effect is sufficient to alter noticeably, but not destabilize important attributes of the resource 3/4 LARGE: Effect is clearly noticeable and sufficient to destabilize important attributes of the resource 3/4 Consistent with the Council on Environmental Quality guidance for NEPA analyses

3/4 Impacts resulting from Category 2 issues are of SMALL significance.
3/4 No new impacts identified.
3/4 Environmental effects of alternatives may reach MODERATE or LARGE significance.
