Sierra Club alleges Meta data center pollution permit undercounts emissions in Richland Parish, Louisiana

The Sierra Club is challenging an air pollution permit approved by the Louisiana Department of Environmental Quality for Meta's Hyperion data center in Richland Parish. The environmental group alleges that Meta's permit application incorrectly calculates and undercounts the facility's potential emissions by excluding certain sources. The Sierra Club is calling for a more stringent major source permit, air monitoring, and a public hearing.
