PLAN IMPLEMENTATION

Regional Coordination
Dredged material disposal planning, plan update, and project review should be undertaken at the regional level. The importance of regional dredged material management stems from two significant problems: dredging and disposal in one jurisdiction may affect other jurisdictions and dredging projects and their related disposal sites are not always located within the same jurisdiction.

It is essential that large projects such as federal navigation channel maintenance be reviewed at a regional level. CREST will assist in this regional review by helping local jurisdictions review dredging permits and federal consistency determinations in the context of a regional Dredged Material Management Plan and by monitoring and periodically updating the Plan. Likewise, for the Corps channel maintenance project, public notice and review takes place periodically for coastal zone consistency and state water quality certification. Coastal zone consistency review is required if modifications to the project are proposed or if new information indicates that coastal zone impacts are different that what had originally been expected.
