VA HB607

Directs the Department of Environmental Quality to conduct a three-year study on aggregate air pollution from data center generators in areas with high concentrations of data centers

Requires modeling of four generator usage scenarios: planned outages, increased outages due to grid strain, demand response use, and use as primary power supply until grid connection

Mandates assessment of cumulative emissions impacts, including geographic analysis of pollution reach on nearby communities and environmental justice considerations for low-income and majority-minority populations

Requires temporal analysis examining public health impacts of continuous versus short-term generator exposure, including effects during high ozone days

Study findings and recommendations on minor air permits and air quality monitoring must be reported to legislative committees and the Secretary of Natural and Historic Resources by October 1, 2029
