ther each alternative (1) is feasible and practical given conditions at the proposed site, and (2) could meet the requirements of Section 316 of the Federal Water Pollution Control Act, and associated Federal and State implementing regulations. For alternatives which satisfy those two criteria, information should be included in the ER that compares the environmental impacts of the proposed system with the alternative system(s). If an alternative system is found to be environmentally preferable to the proposed system, comparative information on the estimated capital and operating cost of the proposed system vs. the estimated capital and operating cost of the environmentally preferable system should be included in the DG-4026, Page 144 ER. The applicant should state the basis for choosing the proposed system over the environmentally preferable system. 9.4.3 Other System Alternatives In unusual circumstances, an applicant may find that consideration of alternatives for other portions of system designs (e.g., the cooling system specific to the service water system) may be warranted. In such cases, the applicant should develop and compare appropriate alternatives and describe its basis for selecting the proposed system. DG-4026, Page 145 Chapter 10 10.0 Conclusions 10.1 Impacts of the Proposed Actions The applicant should summarize and reference the impacts of the proposed action from Chapters 4, 5, and 7. 10.2 Unavoidable Adverse Environmental Effects As required by 10 CFR 51.45(b)(2)), an environmental report (ER) shall discuss “Any adverse environmental effects which cannot be avoided should the proposal is implemented.” Unavoidable adverse environmental impacts are those impacts of the U.S. Nuclear Regulatory Commission (NRC) action and the U.S. Army Corps of Engineers (USACE) action (if it is a cooperating agency), that cannot be avoided in the use of the site and associated offsite facilities. The applicant should provide two tables listing the resource area,
