9. Other aquatic environmental impact analyses that may be needed to support NRC licensing decisions include the following: • entrapment, impingement, and entrainment • noise- and pressure-related impacts on aquatic biota DG-4023, Page 25 • surface water availability and hydrology • interruptions in species movement and migration patterns • introduction and expansion of coverage by thermophilic organisms and invasive species • the potential for displaced species to exceed the carrying capacity in nearby habitats 10. Aquatic environmental monitoring required by environmental permits or regulations should be carefully planned with responsible regulatory agencies. 11. Aquatic environmental baseline studies and impact analyses may be necessary for decommissioning activities that disturb habitats outside of the former operational area. D. IMPLEMENTATION The purpose of this section is to provide information to applicants for nuclear power reactor construction permits, operating licenses, early site permits, limited work authorizations, and combined licenses on how applicants may use this regulatory guide and how the NRC staff intends to use this regulatory guide. The methods described in this regulatory guide will be used in evaluating applications for construction permits, operating licenses, early site permits, combined licenses, and limited work authorizations, which includes information under 10 CFR 51.49(b) or (f), with respect to compliance with applicable regulations governing the siting of new nuclear power plants, unless the applicant proposes an acceptable alternative method for complying with those regulations. Methods that differ from those described in this regulatory guide may be deemed acceptable if they provide sufficient basis and information for the NRC staff to verify that the proposed alternative demonstrates compliance with the applicable NRC regulations. The NRC’s consideration of the information provided by (i) the applicant for, or
