pected water use by the proposed plant. • ESRP 3.4. Obtain input regarding the cooling system for the proposed plant. • ESRP 3.7. Obtain input regarding power transmission systems for the proposed plant (including transmission-corridor clearing and transmission-line construction activities). • ESRP 4.1.1. Provide a description of any construction activities located on a floodplain or wetland. • ESRP 4.2.2. Provide a list of construction activities resulting in hydrologic alterations and their effects on other water users, and additional information to other ESRP Chapter 4.0 reviewers when the reviewer for ESRP 4.2.2 requests that such inputs be made. • ESRPs 4.3.1 and 4.3.2. Provide a list of hydrologic alterations that will affect terrestrial or aquatic ecosystems. • ESRP 4.6. Provide a list of applicant commitments and staff recommendations of practices to minimize hydrologic alterations. • ESRPs 6.1 and 6.3. Provide a list of possible thermal and hydrologic alterations during construction that may require a monitoring program to obtain a National Pollutant Discharge Elimination System (NPDES) permit. • Section 9.4.1. Provide assistance in identifying and evaluating alternative plant design and construction practices that would minimize or avoid hydrologic alterations that result in adverse environmental impacts. Data and Information Needs The type of data and information needed will be affected by site- and station-specific factors, and the degree of detail should be modified according to the anticipated magnitude of the potential impacts. The following data and information should be obtained: October 1999 4.2.1-3 NUREG-1555 ` descriptions of the physical characteristics of the surface-water bodies and groundwater aquifers (from ESRP 2.3.1) ` identification and description of project related construction activities expected to result in hydrologic alterations at the site, transmission corridors, and offsite areas. Activities include construction
