s This section should summarize “any adverse environmental effects which cannot be avoided should the proposal be implemented,” as required by 10 CFR 51.45(b)(2). Chapters 4 and 5 of the ER should identify unavoidable adverse effects, providing a level of detail commensurate with the significance of the effects. 6.4 Irreversible or Irretrievable Resource Commitments This section should summarize “any irreversible or irretrievable commitments of resources which would be involved in the proposed action should it be implemented,” as required by 10 CFR 51.45(b)(5). Irreversible or irretrievable commitments of resources include energy, materials, and resources committed and consumed during the license renewal term and additional waste materials generated by continued plant operations. The ER should briefly describe the magnitude and significance of the resource commitments. Discussions should be proportionate to the significance of the resource commitments. 6.5 Short-Term Use Versus Long-Term Productivity of the Environment This section should summarize “the relationship between local short-term uses of man’s environment and the maintenance and enhancement of long-term productivity,” as required by 10 CFR 51.45(b)(4). For operational impacts, “short-term” indicates the operating life of the plant, and “long-term” suggests the period after the licensed operating life ends and continuing for as long as the plant could have discernible impacts. The term “productivity” should be interpreted broadly to include DG-4015, Page 51 both the productivity of resources useful for human activity and the productivity and stability of ecological systems, even those that are not used directly by humankind.
