Cooling is primarily air-based (similar to a radiator) and does not system capacity and any required upgrades require continuous water use 2. During peak heat, a light water mist is used to enhance cooling • Operational water use is a small fraction of historical efficiency industrial usage 3. Water use is limited and occurs only under these peak conditions 12 1*71 LAKE HAVVKEYE DATA SITE WATER SUPPLY & IPFRASTRUCTURE • Water for data center operations will be supplied by the Bolton Point system and supported by on-site storage • Existing Cayuga Lake intake structure is not required nor permitted for data center operations House Service Pump (700 GPM) • Limited, permitted use of lake water may occur for: a: - r - Construction-related activities such as dust control - System maintenance (e.g., sump pumping, hydro-jetting drains) • Long-term management of the intake structure remains under site owner with - regulatory oversight +y� • Water supply planning and coordination will continue with Bolton Point r+ T .emu o a. LAKE HAVVKEYE DATA TRAFFIC & ACCESS • Construction traffic is temporary and managed through . phased developmentµ . Primary access to the site is via Cayuga Drive r .
