"An environmental group argues Louisiana officials did not account for all of the harmful emissions Meta’s data center in Richland Parish will produce when it approved the facility’s Clean Air Act permit revisions in June.
In comments submitted Thursday to the Louisiana Department of Environmental Quality, the Sierra Club argues that changes to Meta’s Hyperion facility air pollution permit should require it to have a more stringent permit rather than one it obtained.
The state agency issued a minor source permit for the data center when the Sierra Club maintains it should have applied for a more restrictive major source permit.
“This massive project clearly crosses the threshold of what a ‘minor source’ permit would allow,” Margie Vicknair-Pray, Sierra Club Delta chapter projects coordinator, said in a news release. “We deserve the pollution limitations that come with the lawful, more protective permit, and we deserve the chance to have our voices heard at a public hearing.”"
