ction addresses the information related to terrestrial, wetland and aquatic ecological impacts from building activities at the proposed site. The applicant should provide adequate details in the ER to fully determine the impacts to terrestrial and aquatic species and habitats as a result of building activities. 4.3.1 Terrestrial and Wetland Impacts Impacts to terrestrial resources should be based on a conservatively estimated footprint of ground disturbance encompassing the plant and associated facilities. The estimated footprint should also account for temporary features such as laydown areas. Estimates of the footprint used in the ER should be conservative enough to characterize terrestrial impacts in a way not overwhelmed by future minor adjustments to the proposed site layout. Supplementary guidance on some of the more common environmental impact analyses capable of providing some of the information outlined below is available in the most recent version of RG 4.11. Terrestrial Habitats The ER should address the following potential effects on terrestrial habitats from building the proposed nuclear power plant: • Proposed methods for land clearing and grubbing vegetation; temporary and permanent erosion, runoff, and sedimentation control; and dust suppression and construction best management practices (BMPs) that might be used. • Overlays of the estimated footprint of disturbance on terrestrial habitat maps, with separate indications for permanent and temporary disturbance. • Tables quantifying each terrestrial habitat type within the estimated footprint with separate quantifications for permanent and temporary impacts for the site and for each offsite corridor or parcel. • Tables or text comparing estimated losses of each terrestrial habitat type against total extent in the vicinity and a discussion of the relative importance of habitat types lost based on functions (e.g., importance to wildlife). • Description of any plans for restoration (e.g.,
