involve further physical loss of terrestrial habitats or wetlands but can still affect habitat quality and wildlife. Supplementary guidance on some of the more common terrestrial ecology environmental impact analyses is available in the most recent revision of RG 4.11. Terrestrial Habitats The ER should include a discussion of the following potential effects on terrestrial habitats from operating the proposed nuclear power plant: DG-4026, Page 84 • Effects on terrestrial habitats from land-disturbance activities expected (e.g., construction of additional waste storage facilities, including an independent spent fuel storage installation if the applicant has current plans to build such a facility). • Effects on terrestrial habitats from facility- and landscape-maintenance activities (e.g., pesticide use, mowing, danger tree trimming and removal, and trampling by heavy equipment). • Effects of runoff and stormwater management on wetlands and other terrestrial habitats. Ensure compatibility with hydrology sections. • Salinity from cooling-tower drift, or drift from operating other facilities (e.g., evaporation ponds), to affect terrestrial resources. If the maximum estimated ground-level salinity deposition exceeds 1 kg/ha/mo at any location at any time, also include deposition isopleths overlaid on terrestrial habitat maps and an estimate of the area of each habitat type included in each isopleth band. • Fogging and icing that could affect terrestrial species and habitats. • Operation of cooling ponds, evaporation ponds, and other operational water features that could affect adjoining wetlands and other terrestrial habitats. • Use of groundwater and surface water to affect terrestrial habitats (e.g., wetlands, shorelines, and riparian habitats). An overlay of modeled groundwater withdrawal isopleths over terrestrial habitat maps may be helpful if withdrawals could be capable of causing substantial habitat modifications. Information should be consistent
