any potential impacts. The reviewer should coordinate the analysis of hydrologic alterations with the analysis prepared by the reviewer for ESRP 4.2.1 because the analyses for many of the hydro- logic alterations resulting from plant construction will be sufficient to cover subsequent (period of plant operation) alterations due to the physical presence of the plant. Where these alterations will not be fur- ther changed by plant operation, the analysis prepared by the reviewer for Section 4.2.1 should suffice for NUREG-1555 5.2.1-6 October 1999 plant operation. This environmental review should be limited to consideration of hydrologic parameters directly associated with plant operation. The reviewer’s identification of plant operational activities that could result in hydrologic alterations will require knowledge of the site and vicinity physiography, hydrology, and water uses. In addition, the reviewer should be familiar with Federal, State, regional, local, and Native American tribal regulations with respect to hydrology and water use. When evaluating hydrologic alterations resulting from plant operation and the adequacy of the water sources proposed to supply plant water needs, the reviewer should take the following steps: (1) Consider appropriate plant operating conditions (including periods of maximum plant water use, minimum water availability, average plant operation by month and during shutdown) and hydro- logic variations affecting water use. (2) Determine if all known future water uses (including aquatic ecosystems) have been considered. (3) Estimate the effects of operational hydrologic alterations and restrictions on water availability on these users. (4) Identify and analyze any measures proposed by the applicant to minimize or limit these alterations and restrictions. (5) When analyzing water availability, coordinate this review with the reviewer for ESRP 3.3.1. (6) When analyzing hydrologic alterations, coordinate this review with the reviewer for
