s followed, and estimates of uncertainty in model forecasts. The applicant should provide sufficient data to permit staff evaluation of modeling results, including input files used to obtain the model results and a description of any post-modeling analyses used by the applicant. 4.2.2 Water-Use Impacts The applicant should identify those water uses and water users (Chapter 2 of this RG) that are potentially affected by the changes in the quantity and/or availability of water resulting from hydrologic alterations during building. The applicant should evaluate the water-use impacts by quantifying the anticipated reduction in water availability for each water use and provide a description of the analyses performed to determine the impacts. 4.2.3 Water-Quality Impacts The applicant should identify those water uses and water users (Chapter 2 of this RG) that are potentially affected by the changes in water quality resulting from hydrologic alterations during building. The applicant should evaluate the water-quality impacts by quantifying the anticipated reduction in use resulting from the changes in water quality and provide a description of the analyses performed to determine the impacts. DG-4026, Page 64 4.2.4 Water Monitoring The overall plan for protection of waterbodies that may be affected by building activities should be discussed. A description of the proposed measures to ensure compliance with applicable water-quality and water-use standards and regulations should also be provided. When compliance involves monitoring, the monitoring program should be described in sufficient detail to justify the ability of the monitoring to provide timely and accurate information so that appropriate actions can be taken to limit building impacts. 4.3 Ecological Resources This section 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
