nd 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 ESRP 4.2.1 to ensure that the reviewer is aware of the scope and extent of these related reviews and to avoid any duplication of effort. (7) In consultation with the reviewer for ESRP 2.3.1, establish the physical availability of the proposed water sources, including consideration of the drought of record for the region and the 7-day once- in-10-years low flow. (8) In consultation with the reviewer for ESRP 2.3.2, identify the other water uses, rights, and restric- tions of the surface waters and groundwaters, including existing station water uses (e.g., an operat- ing steam electric plant). (9) In consultation with the reviewer for ESRP 3.3.1, determine plant needs for the following plant operating conditions: maximum water consumption, minimum water availability, average opera- tion by month, and plant shutdown. (10) Establish by comparison the adequacy of the water supply to accommodate anticipated plant operating modes. October 1999 5.2.1-7 NUREG-1555 (11) Analyze all operational activities that can alter the quantities of water physically available in nearby hydrologic systems and determine the alterations. ` Consider all water to be used during operation, under various plant operating ( ESRP 3.3.1) and hydrologic (ESRP 2.3.1) conditions. ` Consider all water diversions that change the quantities of water in various parts of water sys- tems (e.g., permanent dewatering) and water rights or allocations obtained for the plant. ` Determine the physical effects (e.g., altered well yields, water levels relative to intake pipes) likely to affect other water users and 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
