  2. Permitting Under the Clean Air Act

Does EPA Actions apply to permits that are jointly issued by EPA and a state, tribal, or local permitting authority with partially delegated permitting authority?

EPA regional offices will decide whether a permit that EPA jointly issues with a state, tribal, or local permitting authority should be considered for prioritization for enhanced outreach as described in EPA Actions on a case‐by‐case basis. EPA will take into account its role and authority in issuing the specific permit and will engage in dialogue with the state, tribal, or local permitting agency to support its decision. For example, EPA does not anticipate applying these documents where EPA’s involvement and authority in issuing the permit is relatively minor in comparison to the state, tribal, or local permitting authority.
