The Mobile District is setting the record straight on recent claims about Mobile Harbor dredging and the decision not to hold a formal public hearing.
The Corps did not deny public input. The District reviewed the hearing requests, written comments, and existing record, and determined the requests did not raise new factual issues, materially different information, or unresolved matters that required a formal public hearing.
A few key facts:
The Mobile Harbor deepening and widening project is complete. We are now in the yearly operations and maintenance phase to keep the federal shipping channel safe and open.
Thin-layer placement is not currently proposed for the present maintenance dredging cycle and has not been used in Mobile Bay in more than a year. Claims tying current oyster impacts directly to ongoing thin-layer placement are not supported by current operations.
In the Mobile Harbor context, thin-layer placement has been evaluated and identified as beneficial use of dredged material. It is not the opposite of beneficial use — it is one of the tools that may be used to manage suitable sediment in a controlled way.
Dredged material management is not a simple choice between “dumping” and “proper disposal.” These decisions depend on sediment type, water conditions, permits, available placement sites, environmental requirements, cost, capacity, and the Corps’ federal responsibility to maintain safe navigation.
We remain committed to maintaining the federal shipping channel while protecting the long-term health of Mobile Bay.
