There are four permit tiers, the purpose of each is defined in subsection 91(m)(2), Title 14, CCR. Use the permit tier decision tree (PDF) to determine which of the four permit tiers apply to your EFP project. Each permit tier matches the purpose of the EFP project with whether it will be facilitated by CDFW. If you are unsure how these permit tiers apply to your project, please contact the EFP Coordinator.
