Page 448, after line 45, insert:

"M.1. The Department of Environmental Quality (Department) shall amend 9VAC25-780, Local and Regional Water Supply Planning, no later than July 1, 2027, to establish criteria for the Department to determine "Cooling Water Scarcity Areas" where the evaporation of water for cooling purposes could have detrimental reductions in the quality or quantity of water available for other beneficial uses, with a particular focus on the Eastern Virginia Groundwater Management Area, as that term is defined in 9VAC25-600-20(A).  The initial promulgation of such regulations is hereby exempted from the Administrative Process Act (§ 2.2-4000 et seq. of the Code of Virginia) and the Department shall complete such regulatory action without further action by the State Water Control Board.

2. In a Cooling Water Scarcity Area, prior to July 1, 2032, a data center, as that term is defined in subdivision A 43 of § 58.1-3506, Code of Virginia, must certify to the Department that for cooling purposes it will use air cooling, closed loop cooling systems, or more efficient cooling systems that become available, to the maximum extent practicable, as determined by the Department, to minimize the use of any type of water for cooling purposes. In the Eastern Virginia Groundwater Management Area, all new data centers who submit a complete application for a Department of Environmental Quality air permit after January 1, 2027, shall either use air cooling systems, 100 percent recycled water and/or stormwater for cooling, or use a closed loop system. The Department, by October 15, 2026, shall conduct a study and provide a plan on the retrofitting of existing data centers in the Eastern Virginia Groundwater Management Area to use air cooling systems, 100 percent recycled water and/or stormwater for cooling, or use a closed loop system."
