Sierra Club Urges Rejection of Meta’s Attempt to Use Minor Source Loophole
AI-summarised brief · reviewed before publication
The Sierra Club filed comments with the Louisiana Department of Environmental Quality (LDEQ) urging rejection of Meta’s request to amend its Hyperion data‑center air permit. Meta seeks to add 44 fossil‑fuel water boilers to its facility, which already operates 31 diesel emergency generators and related equipment under a “minor source” permit approved in July 2025. The club argues that counting emissions from the generators only during emergencies would keep the project below major‑source thresholds, contrary to Clean Air Act requirements. Sierra Club contends LDEQ’s accounting excludes routine emissions, calls for a public hearing, demands stricter reporting and modeling, and recommends battery storage as a cleaner alternative. The dispute centers on whether the expanded emissions exceed the limits of a minor‑source permit for the world’s largest data center.
💡 Why It Matters
- · The outcome will determine if Louisiana enforces stricter major‑source standards for a high‑emission tech project, setting a precedent for how data centers nationwide must account for cumulative pollution.
