nd aquatic ecosystems for those hydrologic systems in which alterations in water quantities have been identified. (12) Analyze the operational activities that can alter hydrologic geometries, flow and circulation pat- terns, and mixing processes and determine the alterations. Hydrologic alterations due to the intake or discharge system are covered in ESRPs 5.3.1.1 and 5.3.2.1. ` Consider other hydrologic alterations (e.g., maintenance dredging, permanent dewatering) with the potential for impacts to water users. ` Report any operational activity that will result in hydrologic alterations to the floodplain to the EPM and to the reviewer for ESRP 5.2.2. ` Analyze and evaluate such alterations in accordance with the instructions provided the reviewer for ESRP 4.2.1. (13) Analyze the operational activities that can alter erosional, depositional, and sediment transport characteristics and determine the alterations. (Note that alterations resulting from intake or discharge system operation are addressed by the reviewers for ESRPs 5.3.1.1 and 5.3.2.1). ` Consider operational activities in relation to the natural processes that would occur in the absence of plant operation. ` For those areas in which alterations in the natural erosional, depositional, and sediment trans- port characteristics have been identified, determine the physical effects (e.g., beach erosion, increased turbidity) likely to affect other water users. (14) Ensure that those operational activities resulting in hydrologic alterations have been identified, and seek confirmation that those alterations resulting in environmental impacts have been described in sufficient detail to allow for the subsequent analysis and assessment of these impacts. (15) Evaluate the adequacy of plant water supplies with respect to plant water needs, using the follow- ing evaluation procedures: NUREG-1555 5.2.1-8 October 1999 ` Determine if the identified alterations in water quantity in the various operationally affected
