An Act to amend the Code of Virginia by adding in Article 1 of Chapter 22 of Title 15.2 a section numbered 15.2-2209.4, relating to siting of data centers; site assessment; high energy use facility. Siting of data centers; site assessment; high energy use facility. Provides that prior to any approval of a rezoning application, special exception application, or special use permit for the siting of a new high energy use facility (HEUF), as defined in the bill, a locality shall require that an applicant perform and submit a site assessment to examine the sound profile of the HEUF on residential units and schools located within 500 feet of the HEUF property boundary. The bill also allows a locality to require that a site assessment examine the effect of the proposed facility on (i) ground and surface water resources, (ii) agricultural resources, (iii) parks, (iv) registered historic sites, and (v) forestland on the HEUF site or immediately contiguous land. The provisions of the bill shall not apply to a site with an existing legislative or administrative approval where an applicant is seeking an expansion or modification of an already existing or approved facility and such expansion does not exceed an additional 100 megawatts or more of electrical power. Finally, the bill provides that its provisions shall not be construed to prohibit, limit, or otherwise supersede existing local zoning authority. This bill is identical to HB 1601.
