Fight in court to uphold state waivers and defend EPA’s authority.
Fund and coordinate legal work that defends Clean Air Act waiver authority against Congressional rollbacks and conflicting federal directives. Focus on strong plaintiffs, durable briefing, and a clear factual record that connects waiver authority to real public-health benefits. Litigation is slow, but it’s the primary path while lawsuits over the rescission and cease-and-desist efforts are underway.
Why this works
- A successful legal outcome (as California argues) would nullify Congress’s attempted repeal, reaffirming the Clean Air Act’s state empowerment.
- It sets a precedent blocking similar attacks and provides long-term certainty.
