ect 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 hydrologic systems are compatible with existing and known future water rights and allocations. ` Describe the physical effects of identified alterations in the quantity of water available to other consumptive water users. ` Describe the physical effects of altered hydrologic geometry, flow, and circulation patterns in relation to non-consumptive water users. When proposed operational activities involving hydrologic alterations to the floodplain are identified, complete the evaluation of these alterations in accordance with the evaluation instructions of Section 4.2.1. ` Describe the physical effects of altered erosional, depositional, and sediment characteristics in relation to other water users, to property and (for those effects not addressed by the reviewers of ESRPs 5.3.1.1 and 5.3.2.1) to aquatic biota. ` Determine if the sources of water proposed to supply plant-water needs will be adequate for these needs, taking into account seasonable variations in water supply and the variations in water needs as a function of operating conditions. If the sources are determined to be inadequate under some conditions, describe the conditions, including seasonal/plant operating- mode factors, the estimated time duration of the inadequacy, and the predicted effect on plant operation. IV. EVALUATION FINDINGS The following information should be included in the EIS: ` a description of plant operational activities that will result in hydrologic alterations, and a description of these alterations and their effects for each affected water body ` the quantities and rates of water diverted, consumed, and discharged during plant operation. Sources of water and points of return should be identified. Variations (seasonal, plant operational modes) should be discussed. ` conclusions with
