may be affected by plant operation. Reference any license renewal activities and modifications to plant operation that may adversely affect EFH. Reference letters and communications with NMFS, and any resulting NMFS memoranda, and include any letters in the appendix to the ER. • Describe the EFH, if any, which might be affected by plant operation. Include the EFH and the species for which it is designated among the biological entities to be analyzed for each aquatic issue. EFH regulations define “‘waters’ to include aquatic areas and their associated physical, chemical, and biological properties that are used by fish and may include aquatic areas historically used by fish where appropriate; ‘substrate’ to include sediment, hard bottom, structures underlying the waters, and associated biological communities; ‘necessary’ to mean the habitat required to support a sustainable fishery and the managed species’ contribution to a healthy ecosystem; and ‘spawning, breeding, feeding, or growth to maturity’ to cover a species’ full life cycle.” Other Acts If license renewal might affect any species protected under Federal law, including the Marine Mammal Protection Act, the Migratory Bird Treaty Act, and the Bald and Golden Eagle Protection Act, the applicant should provide sufficient information to aid the NRC staff in the development of an assessment of the impacts on those species. DG-4015, Page 40 Information and Analysis Content for Other Acts In addition to the general information and analysis content for all ecology issues, the ER should include the following: • Reference any protected species that may be found on or in the vicinity of the site or associated transmission line ROWs that may be affected by plant operation. • Describe the protected species, if any, which might be affected by plant operation. Include those species among the biological entities to be analyzed for each terrestrial or aquatic issue, as appropriate. 4.7 Historic
