Interstate Consistency

Interstate consistency is a special circumstance that occurs when

  • A federal action occurring exclusively in one state (State B) will have effects on the uses or resources of another state’s coastal zone (State A) and
  • State A has the ability to review the action under the Coastal Zone Management Act and NOAA’s interstate consistency regulations.

Only states with approved interstate consistency lists have the ability to apply interstate consistency status under NOAA Federal Consistency Regulations (see 15 C.F.R. part 930, subpart I).
