Section 401 certification: not yet compiled
PermitBird has not transcribed the District of Columbia Clean Water Act section 401 certification for the current nationwide permit reissuance. That is a coverage gap, not a finding that District of Columbia has granted unconditional certification. The certification posture on file here reads "unknown", which in PermitBird's data model means unknown until compiled, not confirmed as clean.
What to check
- Whether District of Columbia has certified, conditioned, waived or denied section 401 certification for the specific nationwide permit a project intends to rely on.
- Any state-specific conditions attached to that certification, which become binding conditions on the nationwide permit inside District of Columbia.
- Whether District of Columbia requires a separate state permit, coastal consistency review, or notification alongside the federal nationwide permit.
