Advocates for a Cleaner Tacoma v. Puget Sound Clean Air Agency

The Puyallup Tribe of Indians filed a petition for review of Washington Pollution Control Hearings Board decisions affirming approvals for a liquefied natural gas facility. The Tribe’s petition raises climate change-related issues, including whether the supplemental environmental impact statement (SEIS) erroneously deemed status quo greenhouse gas emissions to be “insignificant” and whether the SEIS’s reliance on a comparison to a “speculative ‘no action’ scenario” to determine the project’s “net” emissions was arbitrary. The court consolidated the Tribe's appeal with a petition filed by Advocates for a Cleaner Tacoma and certified the appeals for direct review by the Court of Appeals.
